Q: | Why am I receiving this proxy statement/prospectus and proxy card? |
Q: | How does the Livent Board recommend that I vote at the Livent Special Meeting? |
A: | The Livent Board unanimously recommends that Livent stockholders vote “FOR” the Livent Transaction Agreement Proposal, “FOR” the Livent Advisory Compensation Proposal, “FOR” the NewCo Advisory Governance Documents Proposals and “FOR” the Livent Adjournment Proposal. See the section entitled “The Transaction—Recommendation of the Livent Board; Livent’s Reasons for the Transaction” beginning on page 98 of this proxy statement/prospectus. |
Q: | What is the vote required to approve each proposal at the Livent Special Meeting? |
A: | Approval of the Livent Transaction Agreement Proposal requires the affirmative vote of the holders of a majority of the outstanding Livent Shares entitled to vote on the proposal. Because the affirmative vote required to approve the Livent Transaction Agreement Proposal is based upon the total number of outstanding Livent Shares, if you fail to submit a proxy or vote virtually at the Livent Special Meeting, you abstain or you do not provide your bank, broker or other nominee with instructions, as applicable, this will have the same effect as a vote “AGAINST” the Livent Transaction Agreement Proposal. |
Q: | Does my vote matter? |
A: | Yes. The transaction cannot be completed unless the Livent Transaction Agreement Proposal is approved by the Livent stockholders. For Livent stockholders, if you fail to submit a proxy or vote virtually at the Livent Special Meeting, or vote to abstain, or you do not provide your bank, broker or other nominee with instructions, as applicable, this will have the same effect as a vote “AGAINST” the Livent Transaction Agreement Proposal. |
Q: | What will I receive if the transaction is completed? |
A: | If the transaction is completed, each outstanding Livent Share (other than Livent Shares held as treasury stock by Livent or Livent Shares held by any of its subsidiaries) will be converted into the right to receive 2.406 NewCo Shares. The issuance of the NewCo Shares to holders of Livent Shares will be registered with the SEC and the NewCo Shares are expected to be listed and traded on the NYSE under the symbol “ALTM.” See the section entitled “The Transaction Agreement—Merger Consideration” beginning on page 146 of this proxy statement/prospectus. |
Q: | What equity stakes will former Livent stockholders and former Allkem shareholders hold in NewCo? |
A: | Under the Transaction Agreement and based on the Merger Exchange Ratio of Livent Shares for NewCo Shares, the Scheme Exchange Ratio of Allkem Shares for NewCo Shares or CDIs, and Allkem’s and Livent’s respective fully diluted shares as of the date of the Transaction Agreement, it is expected that Livent stockholders will own approximately 44%, and Allkem shareholders will own approximately 56%, respectively, of NewCo immediately following the effective time. |
Q: | What is the value of a NewCo Share? |
A: | Prior to the effective time, there has not been and will not be an established public trading market for NewCo Shares, and the market price of NewCo Shares will be unknown until the commencement of trading following the effective time. The NewCo Shares will reflect the combination of Livent and Allkem based upon the respective exchange ratios for Allkem Shares and Livent Shares, which, in the case of Allkem is one NewCo Share or one CDI for each Allkem Share, and in the case of Livent is 2.406 NewCo Shares for each Livent Share. The exchange ratios are fixed and will not fluctuate up or down based on the market price of Livent Shares, the market price of Allkem Shares or changes in currency exchange rates prior to the completion of the transaction. |
Q: | After the transaction, where can I trade my NewCo Shares? |
A: | At and as of the closing of the transaction, it is expected that the NewCo Shares will be listed and traded on the NYSE under the symbol “ALTM.” |
Q: | What will holders of Livent equity awards receive in the transaction? |
A: | Upon completion of the merger, outstanding Livent equity awards will be treated as follows: |
• | Livent RSUs. At the effective time, each Livent RSU will be assumed by NewCo and will be subject to substantially the same terms and conditions as applied to the related Livent RSU immediately prior to the effective time, except that the Livent Shares subject to such Livent RSUs will be converted into the right to receive, upon vesting, a number of NewCo Shares equal to the product of (A) the number of Livent Shares underlying such Livent RSUs immediately prior to the effective time, multiplied by (B) 2.406. Following such assumption, each assumed Livent RSU that is unvested and outstanding as of the date of signing of the Transaction Agreement will vest on a pro rata basis and, to the extent of such vesting, will be exchanged into the right to receive the merger consideration at the effective time or as soon as practicable thereafter. |
• | Livent PSUs. At the effective time, each Livent PSU will fully vest, with the number of Livent Shares subject to such Livent PSUs determined based on the achievement of the higher of target and actual performance. At the effective time or as soon as practicable thereafter, each Livent PSU will be canceled in exchange for the right to receive the merger consideration. |
• | Livent Options. At the effective time, each Livent Option will be assumed by NewCo and will be subject to substantially the same terms and conditions as applied to the related Livent Option immediately prior to the effective time, except that (x) each such assumed Livent Option will be converted into a stock option to acquire a number of NewCo Shares equal to the product of (A) the number of Livent Shares underlying such assumed Livent Options immediately prior to the effective time, multiplied by (B) 2.406; and (y) the exercise price per NewCo Share will be equal to the product of (A) the original exercise price per Livent Share when such assumed Livent Option was granted, divided by (B) 2.406. |
• | Livent Director RSUs. Immediately prior to the effective time, any Livent Director RSUs will vest in full and be cancelled and converted into the right to receive an amount in cash equal to (A) the number of Livent Shares subject to such Livent Director RSUs immediately prior to the effective time, multiplied by (B) the higher of (i) the first available closing price of the merger consideration and (ii) the closing price per Livent Share as reported in the New York Stock Exchange, on the last trading day preceding the closing date. |
Q: | Do any of the Livent directors or executive officers have interests in the transaction that may differ from or be in addition to my interests as a Livent stockholder? |
A: | Livent’s directors and executive officers have certain interests in the transaction that may be different from, or in addition to, the interests of Livent stockholders generally. These interests include, among other things: |
• | for Livent’s non-employee directors, the treatment of outstanding Livent Director RSUs, which will vest in full and be cancelled and converted into the right to receive an amount in cash. The estimated amount that would be realized by each of Livent’s eight non-employee directors in respect of his or her unvested outstanding Livent Director RSUs if the transaction were to be completed on November 30, 2023 is $127,535. Livent’s non-employee directors only hold Livent Director RSUs and do not hold any other types of equity incentive awards; |
• | for Livent’s executive officers, the treatment of outstanding equity awards described in the section entitled “The Transaction—Interests of Livent’s Directors and Executive Officers in the Transaction—Treatment of Livent Equity Awards” beginning on page 149 of this proxy statement/prospectus; based on the assumptions described thereunder, the estimated aggregate value of accelerated equity awards that would be realized by each of Messrs. Paul W. Graves and Gilberto Antoniazzi and Ms. Sara Ponessa is $6,165,407, $1,607,455 and $1,171,701, respectively; for a detailed breakdown of each executive officer’s holding of the equity awards, please see the tabular disclosure under such section; |
• | for each of Livent’s executive officers, the entitlement to receive certain severance benefits under their individual executive severance agreements with Livent upon a termination of employment by Livent without “cause” or by such individual for “good reason,” in each case within the 24-month period following a “change in control” of Livent; the estimated aggregate value of severance benefits that would be provided to each of Messrs. Graves and Antoniazzi and Ms. Ponessa in connection with such a termination is $12,938,249, $5,200,467 and $3,133,436, respectively; |
• | for each of Mr. Antoniazzi and Ms. Ponessa, the entitlement to receive a cash retention bonus payment in the amount of $250,000 under a retention program established in connection with the transaction, as described in the section entitled “The Transaction—Interests of Livent’s Directors and Executive Officers in the Transaction—Livent Retention Program” beginning on page 118 of this proxy statement/prospectus; |
• | for each of Livent’s executive officers, the entitlement to receive a transaction bonus upon the closing of the merger (subject to continued service through such event) of $500,000 for Mr. Graves and $200,000 for each of Mr. Antoniazzi and Ms. Ponessa, as described in the section entitled “The Transaction—Interests of Livent’s Directors and Executive Officers in the Transaction—Livent Transaction Bonus Program” beginning on page 118 of this proxy statement/prospectus; and |
• | continued indemnification and directors’ and officers’ liability insurance. |
Q: | Will my NewCo Shares acquired in the transaction receive a dividend? |
A: | Once you exchange your Livent Shares after the closing of the transaction, as a holder of NewCo Shares, you will receive the same dividends on NewCo Shares that all other holders of NewCo Shares or CDIs will receive with any dividend record date that occurs after the transaction is completed. Any dividend payments will be made at the discretion of the board of directors of NewCo and will depend upon many factors, including the |
Q: | Will dividends paid by NewCo be subject to tax withholding? |

Q: | What is the difference between holding shares as a shareholder of record and as a beneficial owner? |
A: | If your Livent Shares are registered directly in your name with the transfer agent of Livent, EQ Shareowner Services, you are considered the shareholder of record with respect to those Livent Shares. As the shareholder of record, you have the right to vote, or to grant a proxy for your vote directly to Livent or to a third party to vote, at the Livent Special Meeting. |
Q: | If my Livent Shares are held in “street name” by my bank, broker or other nominee, will my bank, broker or other nominee automatically vote those shares for me? |

You must provide your broker, bank or other nominee with instructions on how to vote your Livent Shares in order to vote. Please follow the voting instructions provided by your broker, bank or other nominee.

Should an ATO Class Ruling not be available for all qualifying Australian resident Allkem shareholders, an ATO Class Ruling that includes (or would include, when issued) a confirmation that qualifying Australian resident shareholders who hold their shares on capital account are eligible to claim rollover relief will be deemed acceptable to Allkem. |

• | by Allkem: |
• | if Livent or a NewCo Party has breached or failed to perform any of its representations, warranties, covenants or other agreements contained in the Transaction Agreement, such that the conditions to Allkem’s obligation to consummate the transaction would not be satisfied (subject to Livent’s right to cure, and provided that Allkem is not then in breach) (the “Allkem Material Breach Termination Right”); |

• | prior to the receipt of the Allkem Shareholder Approval, if there has occurred an Allkem Change of Recommendation in response to an Intervening Event; provided that prior to or concurrently with such termination Allkem pays or causes to be paid to Livent the Allkem Termination Fee (the “Allkem Intervening Event Termination Right”); |
• | prior to the receipt of the Allkem Shareholder Approval, if there has occurred an Allkem Change of Recommendation due to an Independent Expert Event; provided that, in the case such Independent Expert Event is caused by the existence of a Competing Proposal, prior to or concurrently with such termination Allkem pays or causes to be paid to Livent the Allkem Termination Fee (the “Allkem Independent Expert Event Termination Right”); or |

• | if Allkem has breached or failed to perform any of its representations, warranties, covenants or other agreements contained in the Transaction Agreement, such that the conditions to Livent’s obligation to consummate the transaction would not be satisfied (subject to Allkem’s right to cure, and provided that Livent or a NewCo Party is not then in breach) (the “Livent Material Breach Termination Right”); |

• | by mutual written consent of Livent and Allkem; |
• | by either Livent or Allkem: |
• | if the scheme effectiveness has not occurred by 5:00 p.m. (AWST) on February 10, 2024 (subject to extension by either party until May 10, 2024 in order to obtain antitrust or investment screening law or other regulatory approvals), and such outcome was not principally caused by a material breach of certain covenants set forth in the Transaction Agreement by the party seeking to terminate the Transaction Agreement (the “End Date Termination Right”); or |
• | by either Livent or Allkem if (i) any governmental entity of competent jurisdiction has issued a final and non-appealable order that is in effect and permanently restrains, enjoins or otherwise prohibits the consummation of the merger or the scheme or (ii) any governmental entity having jurisdiction over a party has adopted a law that is in effect that permanently makes illegal or otherwise permanently prohibits the consummation of the merger or the scheme (and such outcome was not principally caused by a material breach of any representation, warranty, covenant or agreement set forth in the Transaction Agreement by the party seeking to terminate the Transaction Agreement). In the case of clause (ii) above, if such law arises out of or relates to antitrust laws or investment screening laws, such law will only result in a right to terminate the Transaction Agreement to the extent the violation or contravention of such law as in effect would reasonably be expected to result in criminal liability to any person, personal liability to any director or officer of Allkem, Merger Sub, NewCo or Livent or any of their respective subsidiaries, or a material adverse effect on NewCo and its subsidiaries following the effective time. |

• | (i) by either Livent or Allkem pursuant to the End Date Termination Right or the Allkem Shareholder Approval Failure Termination Right, or by Livent pursuant to the Livent Material Breach Termination Right following an intentional and material breach of a covenant by Allkem, (ii) prior to such termination but after the date of the Transaction Agreement, a bona fide Competing Proposal has been publicly made to Allkem or any of its subsidiaries, has been made directly to the Allkem shareholders generally or otherwise has become public or any person has publicly announced an intention (whether or not conditional) to make a bona fide Competing Proposal to Allkem or, in the case of termination by Livent pursuant to the Livent Material Breach Termination Right, a Competing Proposal has been made publicly or privately to the Allkem Board, and (iii) within 12 months after the date of a termination in either of the cases referred to in the preceding clauses (i) and (ii), Allkem consummates a Competing Proposal or enters into a definitive agreement providing for a Competing Proposal (provided that solely for purposes of this bullet, all references to “20% or more” in the definition of “Competing Proposal” will be deemed to be references to “more than 50%”). |
• | The completion of the transaction contemplated by the Transaction Agreement is subject to a number of conditions and the Transaction Agreement may be terminated in accordance with its terms. Therefore, the timing of closing of the transaction is uncertain and there is a risk that it may not be completed. |
• | The completion of the transaction is subject to receipt of consents, orders and approvals from regulatory and governmental entities, which may delay or prevent entirely the closing of the transaction¸ and conditions may be imposed on the transaction which may reduce the anticipated benefits of the transaction. |
• | Livent may not have discovered certain liabilities or other matters related to Allkem, and Allkem may not have discovered certain liabilities or other matters related to Livent. |
• | The Transaction Agreement contains restrictions on the conduct and business activities of Livent and Allkem, which could adversely affect both companies’ businesses, financial results, financial condition or share prices, as well as restrictions on the ability of Livent to pursue alternatives to the transaction, which may limit the value that Livent stockholders could receive from a transaction. |
• | Directors and executive officers of Livent and Allkem may have interests in the transaction that differ from, are in addition to or conflict with the interests of Livent stockholders and Allkem shareholders generally. |
• | Holders of Livent Shares, collectively, will have a lower ownership and voting interest in NewCo after the transaction than they currently do in Livent, collectively. |
• | Holders of Livent Shares will not have appraisal rights or dissenters’ rights in the merger. |
• | NewCo, Livent and Allkem may be targets of shareholder class actions or derivative actions, which could result in substantial costs and may delay or prevent the transaction from being completed. |
• | The opinion of Livent’s financial advisor does not reflect changes in circumstances that may occur between the signing of the Transaction Agreement and the completion of the transaction. |
• | The NewCo Shares to be received by Livent stockholders in the transaction will have rights that differ from Livent Shares and, in some cases, such rights may afford less protection than the rights currently afforded to holders of Livent Shares. |
• | The merger may fail to qualify as a reorganization under Section 368(a) of the Code, and the merger and the scheme, taken together, may fail to qualify as an exchange described under Section 351(a) of the Code, or the transaction may be subject to Section 367(a)(1) of the Code, potentially causing U.S. holders of Livent Shares to recognize gain for U.S. federal income tax purposes. |
• | The failure to realize the cost savings, synergies and other benefits that the parties expect to achieve from the transaction may materially and adversely affect NewCo’s future results and market value of NewCo Shares following the transaction. |
• | The integration of the businesses of Livent and Allkem may be more difficult, costly or time-consuming than expected, which may materially and adversely affect NewCo’s future results and negatively affect the value of the NewCo Shares following the transaction. |
• | Livent and Allkem will incur significant costs in connection with the transaction, regardless of whether the transaction is completed, and these transaction fees and costs may be greater than anticipated. |
• | The unaudited pro forma condensed combined financial information included in this proxy statement/prospectus may not reflect the actual financial condition and results of operations of NewCo after completion of the transaction. |
• | The financial analyses and unaudited projections considered by Livent and its financial advisors may not be realized. |
• | The prices of commodities, including lithium, are volatile and such volatility may negatively affect NewCo’s revenue and cash flows. |
• | The growth of NewCo’s business, as well as NewCo’s financial condition and financial performance, are dependent on the continued growth in demand for EVs, the growth in demand for lithium chemicals and the growth of the lithium markets generally. |
• | NewCo’s inability to replace the mineral resources used in production (through exploration projects, acquisitions or otherwise) may have an adverse effect on NewCo’s financial performance, and it may be difficult to replace the mineral resources NewCo uses in production because this is often done through exploration activities, which are highly speculative. |
• | NewCo’s operations, financial performance and financial position are dependent on the availability and profitability of mineral resources and ore reserves, and determining such availability and profitability is done by estimates, which are subject to inherent uncertainties. |
• | NewCo’s operations are particularly susceptible to certain physical and other risks, including natural disasters, environmental hazards, pandemics and other catastrophic events, which could disrupt production and have a material adverse effect on NewCo’s financial and operational performance. |
• | The development of NewCo’s facilities is subject to the risk of unexpected difficulties or delays, and any delays or failures in development could materially and adversely affect NewCo’s business, reputation, financial condition, results of operations, cash flows and ability to pay dividends. |
• | NewCo derives a substantial portion of its revenue from a limited number of customers, and the loss of, or a significant reduction in orders from, a large customer could have a material adverse effect on its business, financial condition and results of operations. |
• | NewCo may not satisfy customer qualification processes or customers’ quality standards, and could be subject to damages based on claims brought against NewCo or lose customers as a result of the failure of NewCo’s products to meet certain quality standards. |
• | NewCo’s operations and expansion plans may require additional funding or capital, and if NewCo is unable to secure adequate funds on terms acceptable to NewCo, its liquidity, business and results of operations may be materially and adversely affected. |
• | NewCo’s financial performance, operations and profitability may be adversely affected due to circumstances in the countries where NewCo operates, particularly in Argentina. |
• | NewCo’s operations, financial performance and financial position, including its production and cash flows are limited by its reliance on obtaining and complying with licenses, permits and other approvals required |
• | managing a significantly larger company; |
• | coordinating geographically dispersed organizations; |
• | the potential diversion of management focus and resources from other strategic opportunities and from operational matters; |
• | aligning and executing the strategy of the combined company; |
• | retaining existing customers and attracting new customers; |
• | maintaining employee morale and retaining key management and other employees; |
• | integrating two business cultures, which may prove to be incompatible; |
• | coordinating the work of an integrated workforce and certain third party vendors; |
• | the possibility of faulty assumptions underlying expectations regarding the integration of certain operations; |
• | consolidating certain corporate and administrative infrastructures and eliminating duplicative operations; |
• | consolidating sourcing and procurement logistics with respect to key raw materials; |
• | challenges inherent in ensuring compliance with applicable laws and regulations across a greater number of jurisdictions; |
• | unforeseen expenses or delays associated with the transaction; and |
• | any actions that may be required in connection with obtaining regulatory approvals (or complying with conditions attaching to any regulatory approvals). |
• | as a result of the risk factors listed in this proxy statement/prospectus; |

(1) | The projections provided by Allkem in March 2023 included projections for 2067, but the projections provided by Allkem in May 2022 did not include projections for 2067, so for comparison purposes 2067 is not included. |
• | the Livent Board’s belief that, after a thorough review, the transaction is more favorable to Livent’s stockholders than the potential value that might result from any other alternatives available, including remaining an independent company, or pursuing a significant acquisition or other business combination; |
• | the Livent Board’s expectations relating to the aggregate value of the NewCo Shares to be retained by Livent stockholders after giving effect to the combination of Livent’s and Allkem’s businesses, relative to the value of the Livent Shares on a standalone basis if Livent were not to engage in the transaction, including the fact that, following the transaction, Livent stockholders will have the opportunity to participate in the potential value created by combining Livent and Allkem and benefit from any increases in the value of NewCo Shares; |
• | the Livent Board’s belief that the combined company would create a leading global lithium chemicals producer with enhanced business-critical scale, including a presence in three major lithium geographies (i.e., the South American “lithium triangle,” Western Australia and Canada) and a combined lithium deposit that is among the largest in the world; |
• | the Livent Board’s belief that the combined company would be better able to serve the large and growing global customer base across EV and energy storage value chains, with strong customer relationships from both companies; |
• | the Livent Board’s expectation that the transaction will immediately increase global capabilities, scale and know how after the closing, which is business critical for the industry in which Livent operates; |
• | the Livent Board’s belief that, after a comprehensive analysis, the geographically complementary and relatively low-cost asset portfolios of Allkem will provide value to Livent’s stockholders; |
• | the Livent Board’s belief that the combined company would have a stronger financial profile with a strong combined balance sheet and cash flow generation that allows the delivery of accelerated growth plans; |
• | the Livent Board’s belief that the combined company would have a path to achieving anticipated production capacity of approximately 250 kMT of LCE by the end of calendar year 2027; |
• | the anticipated generation of estimated pre-tax cost synergies of approximately $125 million per year by 2027 (the majority of which is expected to be realized within three years of the transaction) (excluding the impact of approximately $40 million in estimated and non-recurring costs to achieve these synergies), with full run rate cost synergies of approximately $135 million per year by the end of 2032, and one-time capital expenditure savings of approximately $200 million by the end of 2025, mainly driven by asset proximity and co-development in Argentina and Canada, as well as savings at NewCo from operating model integration in the view of Livent’s management; |
• | the financial and other terms and conditions of the Transaction Agreement as reviewed by the Livent Board; |
• | the thoroughness of Livent’s due diligence examinations of Allkem and discussions with Livent’s management and financial and legal advisors; |
• | the fact that for United States federal income tax purposes, the merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the merger and scheme, taken together, are intended to qualify as an exchange described in Section 351(a) of the Code and an exception to Section 367(a) of the Code is expected to apply (assuming applicable holders enter into certain agreements with the IRS); |
• | that the fixed exchange ratio will not adjust downwards or upwards to compensate for changes in the price of Livent Shares or Allkem Shares prior to the consummation of the transaction and therefore provides certainty to Livent’s stockholders as to their pro forma percentage ownership of approximately 44% of the combined company, which is in line with the relative fundamental valuations and the premium paid in similar merger of equal transactions; |
• | the expected greater liquidity and continuity for investors, through a primary listing of NewCo Shares on the NYSE, on which the Livent Shares are currently listed, and a listing on the ASX to enable the trading of CDIs, and the potential inclusion in key S&P indices in the U.S. and the S&P / ASX 200 index in Australia (through pro rata CDI inclusion) based on the implied combined market capitalization of Livent and Allkem as well as other factors; |
• | information and discussions regarding the benefits of size and scale and the expected credit profile of the combined company and the expected pro forma effect of the proposed transaction on these factors; |
• | the opinion of Gordon Dyal & Co. rendered to the Livent Board, to the effect that as of May 10, 2023 and based upon and subject to the factors and assumptions set forth in its opinion, the Merger Exchange Ratio is fair from a financial point of view to the holders of Livent Shares (other than certain excluded shares), as more fully described in the section below entitled “The Transaction—Opinion of Livent’s Financial Advisor” beginning on page 101 of this proxy statement/prospectus; |
• | the likelihood that the transaction will be consummated, based on, among other things: |
○ | the closing conditions to the transaction, which the Livent Board considered to be appropriately limited; and |
○ | the commitment made by Allkem and Livent in the Transaction Agreement to cooperate with each other and use their respective reasonable best efforts to obtain required regulatory approvals, including under the HSR Act, CFIUS laws and applicable foreign antitrust and investment screening laws (including, under certain circumstances and subject to specified limits, Allkem’s commitment to divest certain assets or commit to limitations on the business of Allkem to the extent provided in the Transaction Agreement), as discussed further under “The Transaction Agreement—Efforts to Obtain Required Approvals”; |
• | the terms and conditions of the Transaction Agreement and the course of negotiations of such agreement, including, among other things: |
○ | the ability of Livent, under certain circumstances, to provide information to and to engage in discussions or negotiations with a third party that makes an unsolicited alternative transaction proposal, as further described under “The Transaction Agreement—No Solicitation of Competing Proposals”; |
○ | the ability of the Livent Board, under certain circumstances, to change its recommendation to Livent’s stockholders concerning the transaction, as further described under “The Transaction Agreement—Board Change of Recommendation”; and |
○ | the ability of the Livent Board to terminate the Transaction Agreement under certain circumstances, subject to certain conditions (including payment of a termination fee to Allkem and certain rights of Allkem giving it the opportunity to match a superior proposal), as further described under “The Transaction Agreement—Termination of the Transaction Agreement”; |
• | the termination fee of $64.6 million payable to Allkem upon termination of the Transaction Agreement under specified circumstances is reasonable in light of, among other things, the benefits of the transaction to Livent stockholders and the likelihood that such a fee would not preclude or unreasonably restrict the emergence of a superior proposal, as well as the fact that generally no termination fee is payable by Livent to Allkem if Livent stockholders do not approve the Livent Transaction Agreement Proposal and the Livent Board has not changed its recommendation to Livent stockholders to vote for such proposal and Livent has not breached certain provisions of the Transaction Agreement; |
• | Livent would receive a termination fee of $64.6 million from Allkem in specified circumstances; |
• | the terms of the Transaction Agreement that restrict Allkem’s ability to solicit alternative transaction proposals and, subject to certain exceptions, to provide confidential due diligence information to, or engage in discussions with, a third party interested in pursuing an alternative transaction with Allkem, as further discussed under “The Transaction Agreement—No Solicitation of Competing Proposals”; |
• | the belief of the Livent Board that the end date (of February 10, 2024 (subject to extension by either party until May 10, 2024 in order to obtain required antitrust, investment screening or other regulatory approvals)) provisions of the Transaction Agreement allow for sufficient time to complete the transaction; |
• | the executive leadership arrangements contained in the Transaction Agreement, which provide that, after completion of the transaction, the existing Chief Executive Officer and Chief Financial Officer of Livent will hold the same positions in NewCo; and |
• | the governance arrangements contained in the Transaction Agreement, which provide that, after completion of the transaction, the NewCo board of directors will consist of 14 directors, seven of whom will be from the Livent Board (including Livent’s Chief Executive Officer) and will be nominated by Livent (the Transaction Agreement has since been amended to provide for 12 directors on the NewCo board of directors, but this remains evenly split between members of the Livent Board (including Livent’s Chief Executive Officer) and the Allkem Board). |
• | that the fixed exchange ratio implies a premium to Allkem shareholders based on the share prices of the two companies at the time of announcement and will not adjust upwards to compensate for changes in the price of Livent Shares or Allkem Shares prior to the consummation of the transaction; |
• | the restrictions on the conduct of Livent’s business during the pendency of the transaction, which may delay or prevent Livent from undertaking business opportunities that may arise or may negatively affect Livent’s ability to attract and retain key personnel; |
• | the terms of the Transaction Agreement that restrict Livent’s ability to solicit alternative transaction proposals and to provide confidential due diligence information to, or engage in discussions with, a third party interested in pursuing an alternative transaction, as further discussed under “The Transaction Agreement—No Solicitation of Competing Proposals”; |
• | the potential for diversion of management and employee attrition and the possible effects of the announcement and pendency of the transaction on customers and business relationships; |
• | the amount of time it could take to complete the transaction, including the fact that completion of the transaction depends on factors outside of Livent’s control, including regulatory approvals, approval of Allkem’s shareholders, and approval of the scheme by the Court, and that there can be no assurance that the conditions to the transaction will be satisfied even if the transaction is approved by Livent’s stockholders; |
• | the fact that Allkem would generally not be required to pay a termination fee if the Transaction Agreement is terminated due to regulatory impediments, the failure of Allkem shareholders to approve the transaction, or the failure of the Court to approve the scheme absent a material breach of the Transaction Agreement by Allkem; |
• | the possibility of non-consummation of the transaction and the potential consequences of non-consummation, including the potential negative impacts on Livent, its business and the trading price of the Livent Shares; |
• | the risk that the combined company could be treated as a U.S. corporation (and, therefore, a U.S. tax resident) for U.S. federal income tax purposes following closing pursuant to Section 7874 of the Code, including as a result of a change in applicable law with respect to Section 7874 of the Code or any other U.S. tax law, or official interpretations thereof, or a change in certain facts (including relative values); |
• | the risk that the IRS may assert that the combined company should be treated as a U.S. corporation (and, therefore, a U.S. tax resident) for U.S. federal income tax purposes pursuant to Section 7874 of the Code; |
• | the challenges inherent in the combination of two business enterprises of the size and scope of Livent and Allkem and the cross-border nature of the combined company; |
• | the fact that Livent and Allkem have incurred and will continue to incur significant transaction costs and expenses in connection with the transaction, regardless of whether the transaction is consummated, and that these costs may be greater than anticipated; and |
• | the risks of the type and nature described under the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.” |

• | Annual pre-tax cost synergies estimated at approximately $122 million expected to be achieved by the end of 2027 (the majority of which is expected to be realized within three years of the transaction) (excluding the impact of approximately $40 million in estimated non-recurring costs to achieve these synergies); |
• | Full run rate annual pre-tax cost synergies of approximately $135 million expected to be achieved by 2032; |
• | One time capital expenditure savings of approximately $200 million expected to be achieved by the end of 2025; |
• | Adjustments from Livent’s management to reflect Livent’s Adjusted Allkem Forecasts (which were reflected without input of Allkem), including adjustments to the assumptions underlying Allkem’s management’s projections for production volume, project launch and ramp timing, pricing and cost structure, among other things; and |
• | Operating model integration benefits, based on Livent’s management’s assumption of integrating Livent’s centralized operating model (which were estimated and reflected without input of Allkem). In the view of Livent’s management, deploying Livent’s centralized operating model as assets and products come onstream allows for greater value capture and results in a portion of Allkem’s operations being conducted in jurisdictions where Livent operations are located, including the United States and Singapore, which have lower tax rates than the jurisdictions where Allkem currently operates. |

At the effective time, each Livent RSU will be assumed by NewCo and will be subject to substantially the same terms and conditions as applied to the related Livent RSU immediately prior to the effective time, except that the Livent Shares subject to such Livent RSUs will be converted into the right to receive, upon vesting, a number of NewCo Shares equal to the product of (A) the number of Livent Shares underlying such Livent RSUs immediately prior to the effective time, multiplied by (B) 2.406. Following such assumption, each assumed Livent RSU that is unvested and outstanding as of the date of signing of the Transaction Agreement will vest on a pro rata basis and, to the extent of such vesting, will be exchanged into the right to receive the merger consideration at the effective time or as soon as practicable thereafter. |

(1) | Cash. As described in the section above entitled “—Existing Livent Executive Severance Agreements,” the amount shown is equal to (A) three times (and two times for Ms. Ponessa) the sum of base salary plus target annual incentive, calculated by using the highest annualized base salary and target annual incentive available to the NEO during his/her career with Livent; plus (B) the pro rata amount of any annual incentive award payable as of the effective time. |
(2) | Equity. As described in the section above entitled “—Treatment of Livent Equity Awards,” the amount shown represents the value of the Livent RSUs, Livent PSUs and Livent Options, calculated as follows: |
Named Executive Officers | | | Livent RSUs(a) | | | Livent PSUs(b) | | | Livent Options(c) | | | Value of All Equity Awards |
Paul W. Graves | | | $3,687,453 | | | $1,085,354 | | | $1,392,600 | | | $6,165,407 |
Gilberto Antoniazzi | | | $960,381 | | | $278,969 | | | $368,105 | | | $1,607,455 |
Sara Ponessa | | | $701,861 | | | $215,112 | | | $254,728 | | | $1,171,701 |
(a) | All unvested Livent RSUs will be assumed by NewCo and then vest on a pro rata basis upon the change in control, even if the NEO was not terminated. The amounts shown reflect the market value of the Livent RSUs calculated based on the stock price of $25.37 per share (the average closing market price over the first five business days following the first public announcement of the transaction on May 10, 2023), consisting of (i) for Mr. Graves: $2,264,515 that would accelerate on a “single-trigger” basis upon the change in control and an additional $1,422,938 that would accelerate on a “double-trigger” basis if the NEO is terminated within two years following the change in control due to either a termination by Livent or its applicable affiliate without “cause” or a resignation by the NEO with “good reason,” (ii) for Mr. Antoniazzi: $596,631 that would accelerate on a “single-trigger” basis and an additional $363,750 that would accelerate on a “double-trigger” basis and (iii) for Ms. Ponessa: $419,394 that would accelerate on a “single-trigger” basis and an additional $282,467 that would accelerate on a “double-trigger” basis. |
(b) | All unvested PSUs will accelerate in full at the better of target or actual performance upon the change in control. The amounts shown reflect the market value of the accelerated Livent PSUs assuming target performance, based on the stock price of $25.37 per share. |
(c) | All Livent Options will be assumed by NewCo upon the change in control. As disclosed above, each Livent Assumed Option will be subject to substantially the same terms and conditions as applied to the related Livent Option immediately prior to the effective time. No converted Livent Options vest at the effective time based solely on the closing of the merger. The amounts shown reflect the market value of the Livent Options that would accelerate on a “double-trigger” basis in the event that an NEO is terminated within two years following the change in control due to either a termination by Livent or its applicable affiliate without “cause” or a resignation by the NEO with “good reason,” calculated at a per share value of $25.37. The ultimate value of accelerated vesting for the foregoing options will depend on the stock price on the date of exercise. |
(3) | Pension/NQDC. The amount shown is equal to three times (and two times for Ms. Ponessa) the sum of the annual company contributions made on the NEO’s behalf to the Livent Savings and Investment Plan and the Livent Nonqualified Savings Plan. |
(4) | Perquisites / Benefits. Represents welfare benefits of health care and dental, life insurance and disability insurance continuation for three years (and two years for Ms. Ponessa). The amounts shown are the estimated cost to Livent for such benefits during the period. |
(5) | The amounts reported in this column reflect (A) the maximum amount that could be paid by Livent to the NEOs with respect to outplacement services, (B) the cash retention bonuses that will be payable to Mr. Antoniazzi and Ms. Ponessa (consisting of $250,000 for each of Mr. Antoniazzi and Ms. Ponessa) and (C) the cash transaction bonuses that will be payable to Mr. Graves, Mr. Antoniazzi and Ms. Ponessa (consisting of $500,000, $200,000 and $200,000, respectively). The NEOs are entitled to outplacement services, which are capped at 15% of the NEO’s base salary. The actual amounts paid in respect of such services will be determined based upon the outplacement services obtained, if any, by an NEO upon termination. The cash retention bonuses for Mr. Antoniazzi and Ms. Ponessa will be payable on the one-year anniversary of the closing of the merger, contingent upon their continued employment with the combined company or any applicable affiliate through the one-year anniversary of the closing of the merger or the prior termination of their employment by the combined company or any applicable affiliate without “cause.” The cash transaction bonuses will be payable upon the closing of the merger, contingent upon continued employment through such event. For additional information on the retention bonus program and the transaction bonuses, see the sections above entitled “—Livent Retention Program” and “—Livent Transaction Bonus Program.” |
• | If Role Not Made Redundant. No later than the date of scheme effectiveness, each outstanding and unvested Allkem Performance Right held by an employee of Allkem whose role is not being made redundant in connection with the transaction will vest in the proportion to be determined by the Allkem Board, with any performance conditions deemed to have been met. However, pursuant to the terms of the Transaction Agreement, no less than 60% and no more than 70% of the aggregate number of outstanding and unvested Allkem Performance Rights that are held by employees of Allkem whose roles are not being made redundant in connection with the transaction may vest by no later than the date of scheme effectiveness. The vested Allkem Performance Rights will be exchanged for Allkem Shares prior to the Scheme Record Date and be eligible to receive the scheme consideration in connection with the scheme. The remaining outstanding and unvested Allkem Performance Rights will lapse and be of no further force or effect by no later than the date of scheme effectiveness and, as soon as practicable following the date of scheme implementation, NewCo will grant replacement awards to the prior holders who are employees of NewCo, which replacement awards will (i) be substantially comparable in value to the corresponding lapsed Allkem Performance Rights as of immediately prior to the date of scheme effectiveness, (ii) be in respect of NewCo Shares and (iii) if the employment of the holder of a replacement award is terminated as a result of redundancy in the 12 months following the date of scheme implementation, vest in full upon such termination. |
• | If Role Made Redundant. No later than the date of scheme effectiveness, each outstanding and unvested Allkem Performance Right held by an employee of Allkem whose role is being made redundant in connection with the transaction will vest in the proportion to be determined by the Allkem Board, with any performance conditions deemed to have been met. Pursuant to the terms of the Transaction Agreement, up to 100% of the aggregate number of outstanding and unvested Allkem Performance Rights that are held by employees of Allkem whose roles are being made redundant in connection with the transaction may vest by no later than the date of scheme effectiveness. The vested Allkem Performance Rights will be exchanged for Allkem Shares prior to the Scheme Record Date and be eligible to receive the scheme consideration in connection with the scheme. The remaining outstanding and unvested Allkem Performance Rights will lapse and be of no further force or effect by no later than the date of scheme effectiveness. |

• | the view that the transaction would create a leading global lithium chemicals producer with enhanced business-critical scale, including a presence in three major lithium geographies (i.e., the South American “lithium triangle,” Western Australia and Canada) and a combined lithium deposit base that is among the largest in the world; |
• | the view that the combined company would have a highly complementary and vertically integrated business model, including exposure to a broad range of lithium chemical products, low-cost assets and a more resilient supply chain and enhanced operating flexibility and efficiency to better serve customers; |
• | the view that the combined company would have a path to de-risk and accelerate growth, including achieving anticipated production capacity of approximately 250 kMT of LCE by calendar year 2027, due to its pipeline of growth projects and complementary expertise in hard rock mining, conventional and direct lithium extraction-based processes and lithium carbonate production and hydroxide processing; and |
• | the view that the combined company would have a deeper pool of technical, capital and projects expertise in a human resource constrained industry, which would draw on best practice learnings from both companies. |
• | the fixed exchange ratio for the consideration payable to Allkem’s shareholders in the transaction was based on each company’s estimated relative fundamental valuation contribution to the combined company’s risk-adjusted net asset value, on a pre-synergy basis; |
• | the fact that the transaction is expected to result in Allkem’s shareholders owning approximately 56% of the combined company, compared to 53% that was implied by the volume-weighted average market prices of Allkem Shares and Livent Shares over the one-month period preceding the signing of the Transaction Agreement, which implies a premium of approximately 14% to Allkem’s shareholders (measured as the difference between the agreed Merger Exchange Ratio and the implied merger exchange ratio based on the prices of Allkem Shares and Livent Shares using volume weighted average share prices over this period, and calculated assuming Allkem shareholders exchange their Allkem Shares for NewCo Shares at an implied price of A$13.54 per share, which in turn was calculated using the one-month volume weighted average price of Livent Shares over the same period ($21.81), the Merger Exchange Ratio, and the average of the daily USD to AUD foreign exchange rates over the same period); |
• | the view that the transaction would be accretive to Allkem’s and Livent’s shareholders on a net asset value per share basis following anticipated synergies; |
• | the view that the transaction would provide approximately $125 million per year of estimated annual pre-tax cost synergies by 2027 (with the majority expected to be realized within three years of the transaction) (excluding the impact of approximately $40 million in estimated non-recurring costs to achieve these synergies), and approximately $200 million of estimated one-time capital expenditure savings expected by the end of 2025 largely from consolidated infrastructure, streamlined construction and procurement operations and leveraged complementary engineering work; |
• | the view that the combined company would have a stronger financial profile and be positioned to accelerate and deliver upon a growth strategy with a strong balance sheet (including combined liquidity of approximately $1.4 billion based on the companies’ respective publicly reported information as of March 31, 2023 and limited indebtedness) and positive cash flow generation; and |
• | the view that the transaction is generally expected to be cash-free and tax-free for both Allkem’s shareholders and Livent’s stockholders. |
• | the view that greater value is expected to be created for Allkem’s shareholders as the expected owners of approximately 56% of the combined company than as the owners of all of Allkem on a standalone basis, largely due to the factors described above; |
• | the view that the transaction would be more value accretive for Allkem’s shareholders when compared to other available strategic alternatives considered by the Allkem Board; |
• | the view that the transaction would provide Allkem’s shareholders with greater liquidity with respect to their investments, including through the primary listing of the NewCo Shares on the NYSE and a foreign exempt quotation of the CDIs on the ASX and seeking inclusion in key S&P indexes in the U.S. and the S&P / ASX 200 index in Australia (through pro rata CDI inclusion) based on the implied combined market capitalization of Livent and Allkem as well as other factors; |

○ | Mr. Peter Coleman, the current Chairman of the Allkem Board, serving as the Chair of the NewCo board of directors; and |
○ | directors nominated by Allkem serving as the Chairs of the Audit Committee and the Compensation Committee of the NewCo board of directors; |

• | the other terms and conditions of the Transaction Agreement and related documentation, including: |
○ | the nature and scope of the representations, warranties and covenants of Livent and Allkem in the Transaction Agreement; |
○ | the restrictions on Livent soliciting alternative transaction proposals from third parties and/or providing confidential due diligence information to, or engaging in discussions with, third parties interested in pursuing alternative transactions, except under certain circumstances; |
○ | the fact that Livent must pay Allkem a termination fee of $64.6 million if the Transaction Agreement is terminated under certain circumstances; |
○ | the fact that Allkem would not be required to pay Livent a termination fee if the Transaction Agreement is terminated due to regulatory impediments or, in the absence of a Competing Proposal, due to the failure of Allkem’s shareholders to approve the scheme, the failure of the Independent Expert to conclude that the scheme is in the best interests of Allkem’s shareholders or the failure of the Court to approve the scheme; |
○ | the provisions permitting Allkem, subject to certain terms and conditions, to change its board of directors’ recommendation or to propose or enter into an alternative transaction, and terminate the Transaction Agreement, in response to a Superior Proposal or an Intervening Event; |
○ | the right, subject to certain terms and conditions, to terminate the Transaction Agreement if the scheme is not effective on or before February 10, 2024 (subject to extension by either party until May 10, 2024 in order to obtain required antitrust, investment screening or other regulatory approvals); |
○ | the nature and scope of the restrictions on the conduct of Livent’s business until the consummation of the transaction or the termination of the Transaction Agreement; |
○ | the expectation that the restrictions on Allkem under the Transaction Agreement provide Allkem with sufficient operating flexibility to conduct its business in the ordinary course between the execution of the Transaction Agreement and the consummation of the transaction; |
○ | the fact that Allkem’s aggregate monetary liability for any breaches of the terms of the Transaction Agreement is limited to $64.6 million, except in the case of intentional and material breach or fraud; |
○ | the nature and scope of the obligations of Livent to use its reasonable best efforts to obtain the required governmental approvals under the antitrust and investment screening laws of specified jurisdictions, including to potentially agree to certain obligations and restrictions (including divestitures) that would not reasonably be expected to have a material and adverse impact on Livent or the benefits or synergies that Livent expects to realize from the transaction; |
○ | the fact that Allkem’s obligation to consummate the transaction is conditioned on its receipt of confirmation from the ATO that either the ATO is prepared to issue a class ruling or there are no material impediments which may prevent the ATO from issuing a class ruling confirming that qualifying Australian resident shareholders of Allkem will be eligible to choose rollover relief to the extent they receive NewCo Shares or CDIs in connection with the scheme; and |

○ | the likelihood that the ATO would confirm that either it is prepared to issue a class ruling or there are no material impediments which may prevent it from issuing a class ruling confirming that qualifying Australian resident shareholders of Allkem will be eligible to choose rollover relief to the extent they receive NewCo Shares or CDIs in connection with the scheme on a timely basis; and |
○ | the likelihood that the required governmental approvals under the antitrust and investment screening laws of specified jurisdictions would be received without the imposition of certain obligations and restrictions (including divestitures) that would reasonably be expected to have a material and adverse impact on a party or the benefits or synergies that a party expects to realize from the transaction on a timely basis. |
• | the challenges inherent in completing the transaction on the anticipated timetable, including the fact that consummation of the transaction depends on factors outside of Allkem’s control such as regulatory approvals, conclusion by the Independent Expert that the scheme is in the best interests of Allkem’s shareholders, approval of the scheme by the Court, approval of the scheme by Allkem’s shareholders and approval of the transaction by Livent’s stockholders, and that there can be no assurance that the conditions that must be satisfied or waived for the transaction to occur will be satisfied or waived; |
• | the risk that required regulatory approvals, the receipt of which is beyond Allkem’s and Livent’s control, may be delayed, conditioned or denied; |
• | the risk that Livent’s stockholders or Allkem’s shareholders vote against the proposals at the Livent Special Meeting or Allkem’s scheme meeting, respectively; |
• | the challenges inherent in integrating the businesses, operations and workforces of Livent with those of Allkem, and developing and executing a successful strategy and business plan for the combined company; |
• | the potential for management diversion and employee attrition during the period prior to the consummation of the transaction, and the potential negative effects on Allkem’s and, ultimately, the combined company’s, business operations and relationships; |
• | the risk that, despite the efforts of Allkem and Livent prior to the consummation of the transaction, the combined company may lose its relationships with one or more significant customers, suppliers or other strategic partners or be unable to retain key officers or other employees; |
• | the risk of not capturing the anticipated cost savings and synergies and performance improvements, and the risk that other anticipated benefits described above might not be realized, take longer to achieve or involve additional costs to achieve; |
• | the challenges inherent in the combination of two business enterprises of the size and scope of Allkem and Livent and the cross-border nature of the combined company; |
• | the fact that Allkem and Livent have incurred and will continue to incur significant transaction costs and expenses in connection with the transaction, regardless of whether the transaction is consummated, and that those costs may be greater than anticipated; |
• | the risk that the accounting treatment of the transaction differs from what the parties had anticipated at the time of execution of the Transaction Agreement, and that additional expenses and inefficiencies may result from that treatment; |
• | the risk that NewCo could be treated as a domestic corporation for U.S. federal income tax purposes, and the tax expenses and inefficiencies that may result from that treatment; |
• | the risks associated with becoming a U.S. domestic registrant subject to U.S. securities laws, including associated costs, compliance and reporting requirements; |
• | the risks associated with establishing NewCo’s primary stock exchange listing in the U.S. on the NYSE and the risk that NewCo may not be included in indices in the U.S. and Australia (including an S&P index in the U.S. and the S&P / ASX 200 index in Australia); |
• | certain terms of the Transaction Agreement, including, among other things: |
○ | the restrictions on Allkem soliciting alternative transaction proposals from third parties and/or providing confidential due diligence information to, or engaging in discussions with, third parties interested in pursuing alternative transactions, except under certain circumstances; |
○ | the fact that Allkem must pay Livent a termination fee of $64.6 million if the Transaction Agreement is terminated under certain circumstances; |
○ | the provisions permitting Livent, subject to certain terms and conditions, to change its board of directors’ recommendation or propose or enter into an alternative transaction, and to terminate the Transaction Agreement, in response to a Superior Proposal or an Intervening Event; |
○ | the nature and scope of the obligations of Allkem to use its reasonable best efforts to obtain the required governmental approvals under the antitrust and investment screening laws of specified jurisdictions, including, under certain circumstances and subject to specified limits, potentially being required to divest certain assets or commit to limitations on the business of Allkem to the extent provided in the Transaction Agreement; |
○ | the nature and scope of the restrictions on the conduct of Allkem’s business until the consummation of the transaction or termination of the Transaction Agreement, which may delay or prevent Allkem from undertaking certain opportunities that may arise; |
○ | the fact that Livent’s aggregate monetary liability for any breaches of the terms of the Transaction Agreement is limited to $64.6 million, except in the case of intentional and material breach or fraud; and |
○ | the fact that the definition of “Material Adverse Effect” has a number of customary exceptions, as described in detail in the section entitled “The Transaction Agreement—Conditions That Must Be Satisfied or Waived for the Transaction to Occur” beginning on page 167 of this proxy statement/prospectus, and is generally a very high standard as applied by courts; and |
• |
• | NewCo is a shell company and was formed in contemplation and for the purpose of completing the transaction; |
• | Livent initiated the negotiation of the transaction; |
• | The Chief Executive Officer and the Chief Financial Officer of Livent will continue as the Chief Executive Officer and Chief Financial Officer, respectively, of NewCo and Livent’s other executive officer, Ms. Sara Ponessa, General Counsel, will continue to perform the same role for NewCo; |
• | Under the NewCo articles of association, the Chief Executive Officer has the authority to select NewCo’s officers other than those required to be elected by the NewCo board of directors; |
• | The NewCo board of directors will be split evenly with six nominees from each of Livent and Allkem with equal voting rights, and matters on which the NewCo board of directors is deadlocked will not be approved (in this regard, the appointment of Mr. Peter Coleman, who is Allkem’s current Chairman, as the Chair of the NewCo board of directors did not impact the analysis because NewCo’s Chair will not have any tie-breaking or other special voting powers or any ability to affect the voting powers of the other NewCo directors under NewCo’s articles of association); |
• | There was an implied approximately 14% premium (measured as the difference between the agreed Merger Exchange Ratio and the implied merger exchange ratio based on the prices of Allkem Shares and Livent Shares, using volume weighted average share prices over one month from April 10, 2023 through May 9, 2023, the day immediately prior to the date of the Transaction Agreement) to Allkem shareholders; |
• | Notwithstanding that former shareholders of Allkem will own approximately 56% of the NewCo Shares (either directly or through CDIs) compared to Livent stockholders owning approximately 44%, on a fully diluted basis, the shareholders of NewCo will be diffuse with no holder or group of holders having a significant voting or minority ownership and there is no large minority interest and, as discussed above, the NewCo board of directors representing the shareholders will be split evenly with six nominees from each of Livent and Allkem, and each director (including the Chair) will have equal voting rights; and |
• | Livent had a similar total market capitalization to Allkem prior to the announcement of the transaction, notwithstanding Allkem’s larger size in terms of assets, earnings and revenues as of the date of this proxy statement/prospectus. |
• | certain financial institutions; |
• | an insurance company; |
• | a regulated investment company, real estate investment trust, or mutual fund; |
• | a dealer or electing trader in securities that uses a mark-to-market method of tax accounting; |
• | a person who holds Livent Shares, or will hold NewCo Shares, as the case may be, as part of a “straddle,” integrated transaction or similar transaction; |
• | a person who holds Livent Shares, or will hold NewCo Shares, as the case may be, in an individual retirement or other tax-deferred account; |
• | a person whose functional currency is not the U.S. dollar; |
• | a person who received Livent Shares, or who acquires NewCo Shares, as the case may be, pursuant to the exercise of employee stock options or otherwise as compensation or in connection with the performance of services; |
• | a person required for U.S. federal income tax purposes to conform the timing of income accruals to their financial statements under Section 451 of the Code; |
• | a person who holds Livent Shares, or will hold NewCo Shares, as the case may be, in connection with a trade or business conducted outside of the U.S.; |
• | an entity or arrangement treated as a partnership or other flow-through entity (including an S corporation or a limited liability company treated as a partnership or disregarded entity for U.S. federal income tax purposes); or |
• | a tax-exempt entity. |
• | an individual citizen or resident of the U.S.; |
• | a corporation or other entity taxable as a corporation created in or organized under the laws of the U.S., any state therein or the District of Columbia; or |
• | an estate or trust the income of which is subject to U.S. federal income tax without regard to its source. |
• | The exchange of Livent Shares by U.S. holders for NewCo Shares in the merger will not result in the recognition of any gain or loss with respect to a U.S. holder’s Livent Shares (except with respect to cash received in lieu of fractional shares, as discussed below). |
• | The aggregate tax basis of any NewCo Shares a U.S. holder receives in exchange for all of its Livent Shares in the merger, including fractional NewCo Shares deemed received and redeemed or sold, as discussed below, will be the same as the aggregate tax basis of its Livent Shares. |
• | The holding period of any NewCo Shares (including fractional NewCo Shares deemed received and redeemed as discussed below) a U.S. holder receives in the merger will include the holding period of the Livent Shares it exchanged for such NewCo Shares. |
• | If a U.S. holder has differing bases or holding periods in respect of its Livent Shares, the U.S. holder must determine the bases and holding periods in the NewCo Shares received in the merger separately for each identifiable block (that is, stock of the same class acquired at the same time for the same price) of Livent Shares the U.S. holder exchanges. |
• | Because NewCo will not issue any fractional NewCo Shares in the merger, if a U.S. holder exchanges Livent Shares in the merger, and would otherwise have received a fraction of a NewCo Share, the U.S. holder will receive cash. In such a case, the U.S. holder will be treated as having received a fractional share and having received such cash in redemption of the fractional share. The amount of any capital gain or loss the U.S. holder recognizes will equal the amount of cash received with respect to the fractional share less the ratable portion of the tax basis of the Livent Shares surrendered that is allocated to the fractional share. Capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in the Livent Shares is more than one year on the date of closing of the merger. The deductibility of capital losses is subject to limitations. |

• | a company resident for tax purposes in a Relevant Territory, provided such company is not under the control, whether directly or indirectly, of a person or persons who is or are resident in Ireland; |
• | a company, wherever resident, that is controlled, directly or indirectly, by persons resident in a Relevant Territory and who is or are (as the case may be) not controlled by, directly or indirectly, persons who are not resident in a Relevant Territory; |
• | a company, wherever resident, whose principal class of shares (or those of its 75% direct or indirect parent) is substantially and regularly traded on a stock exchange in Ireland, on a recognized stock exchange in a Relevant Territory or on such other stock exchange approved by the Irish Minister for Finance; or |
• | a company, wherever resident, that is wholly owned, directly or indirectly, by two or more companies where the principal class of shares of each of such companies is substantially and regularly traded on a stock exchange in Ireland, on a recognized stock exchange in a Relevant Territory or on such other stock exchange approved by the Irish Minister for Finance; |
• | The NewCo board of directors will consist of 12 directors, six of whom will be from the existing Allkem Board, including the Chairman of the Allkem Board as of immediately prior to the scheme implementation, and will be nominated by Allkem, and six of whom will be from the existing Livent Board, including the Chief Executive Officer of Livent as of immediately prior to the effective time, and will be nominated by Livent. Pursuant to the Transaction Agreement, Livent and Allkem have since nominated the following individuals for the NewCo board of directors: (i) Michael F. Barry, (ii) Peter Coleman, (iii) Alan Fitzpatrick, (iv) Paul W. Graves, (v) Florencia Heredia, (vi) Leanne Heywood, (vii) Christina Lampe-Önnerud, (viii) Pablo Marcet, (ix) Steven T. Merkt, (x) Robert C. Pallash, (xi) Fernando Oris de Roa and (xii) John Turner; |
• | the initial Chair of the NewCo board of directors will be the Chairman of the Allkem Board as of immediately prior to the scheme implementation; |
• | the initial Chief Executive Officer and Chief Financial Officer of NewCo will be the Chief Executive Officer and Chief Financial Officer, respectively, of Livent as of immediately prior to the effective time; |
• | NewCo’s applicable corporate governance policies will require that there be a mandatory retirement age of 75 for the members of the NewCo board of directors; |
• | NewCo’s applicable corporate governance policies will require that the NewCo board of directors have the following committees: an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, a Sustainability Committee and such other committees as determined by the NewCo board of directors from time to time; |
• | each of the Chair of the Audit Committee and the Compensation Committee will be an Allkem Nominee; |
• | each of the Chair of the Nominating and Corporate Governance Committee and the Sustainability Committee will be a Livent Nominee; and |
• | the executive leadership structure of NewCo (other than the Chief Executive Officer and Chief Financial Officer), and the persons to fill such positions, in each case as of the effective time, were contemplated to be mutually determined in good faith by Livent and Allkem prior to the scheme effectiveness with the objective of filling such positions with the most qualified persons. Pursuant to the Transaction Agreement, the parties have since made this determination, including that Livent’s current General Counsel, Ms. Sara Ponessa, will assume the role of General Counsel of NewCo, as well as determining the rest of the broader senior management team of NewCo as of the effective time, consisting of an approximately equal split of employees from each of Allkem and Livent. |

• | Livent RSUs. At the effective time, each outstanding time-vested restricted stock unit with respect to Livent Shares (“Livent RSU”) will be assumed by NewCo and will be subject to substantially the same terms and conditions as applied to the related Livent RSU immediately prior to the effective time, except that the Livent Shares subject to such Livent RSUs will be converted into the right to receive, upon vesting, a number of NewCo Shares equal to the product of (i) the number of Livent Shares underlying such Livent RSUs immediately prior to the effective time, multiplied by (ii) 2.406. Following such assumption, each assumed Livent RSU that is unvested and outstanding as of the date of signing of the Transaction Agreement will vest on a pro rata basis and, to the extent of such vesting, will be exchanged into the right to receive the merger consideration, plus the fractional share consideration (if any), at the effective time or as soon as practicable thereafter. |
• | Livent PSUs. At the effective time, each outstanding performance-based restricted stock unit with respect to Livent Shares (“Livent PSU”) will fully vest, with the number of Livent Shares subject to such Livent PSUs determined based on the achievement of the higher of target and actual performance. At the effective time or as soon as practicable thereafter, each Livent PSU will be canceled in exchange for the right to receive the merger consideration, plus the fractional share consideration (if any). |
• | Livent Options. At the effective time, each outstanding time-vested stock option (whether vested or unvested) with respect to Livent Shares (the “Livent Option”) will be assumed by NewCo (each, a “Livent Assumed Option”). Each Livent Assumed Option will be subject to substantially the same terms and conditions as applied to the related Livent Option immediately prior to the effective time, except that (x) each such Livent Assumed Option will be converted into a stock option to acquire a number of NewCo |
• | Livent Director RSUs. Notwithstanding anything to the contrary, immediately prior to the effective time, any outstanding time-vested restricted stock unit held by any Livent non-employee directors with respect to Livent Shares (“Livent Director RSUs”) will vest in full and be cancelled and converted into the right to receive an amount in cash equal to (i) the number of Livent Shares subject to such Livent Director RSUs immediately prior to the effective time, multiplied by (ii) the higher of (A) the first available closing price of the merger consideration and (B) the closing price per share of Livent Shares as reported in the NYSE, on the last trading day preceding the closing date. |

• | if, prior to the receipt of the Livent Stockholder Approval, (i) the Livent Board effects a Livent Change of Recommendation, or (ii) an intentional and material breach by Livent of the covenant relating to calling the Livent Special Meeting for the purpose of obtaining the Livent Stockholder Approval has occurred (the “Allkem Adverse Change Termination Right”); |
• | by Livent: |
• | if Allkem has breached or failed to perform any of its representations, warranties, covenants or other agreements contained in the Transaction Agreement, which breach or failure to perform (i) would cause the conditions to Livent’s obligation to consummate the transaction relating to the accuracy of Allkem’s representations and warranties and compliance with its covenants and agreements contained in the Transaction Agreement to not be satisfied, and (ii) is either incapable of being cured or is not cured by the earlier of (A) the end date and (B) 30 days following written notice by Livent thereof (provided that any of Livent or a NewCo Party is not then in breach of any representation, warranty, covenant or other agreement contained in the Transaction Agreement which breach would cause the conditions to Allkem’s obligation to consummate the transaction relating to the accuracy of Livent’s representations and warranties and compliance with its covenants and agreements contained in the Transaction Agreement to not be satisfied) (the “Livent Material Breach Termination Right”); |

• | if, prior to the receipt of the Allkem Shareholder Approval, (i) the Allkem Board effects an Allkem Change of Recommendation, or (ii) an intentional and material breach by Allkem of the covenant relating to applying for an order of the Court pursuant to the Australian Corporations Act to convene the scheme meeting and otherwise taking required steps to cause the scheme meeting to be called for the purpose of obtaining the Allkem Shareholder Approval has occurred (the “Livent Adverse Change Termination Right”). |
• | by mutual written consent of Livent and Allkem; or |
• | by either Livent or Allkem: |
• | if the scheme effectiveness has not occurred by 5:00 p.m. (AWST) on February 10, 2024 (subject to extension by either party until May 10, 2024 in order to obtain antitrust or investment screening law or other regulatory approvals), and such outcome was not principally caused by a material breach of certain covenants set forth in the Transaction Agreement by the party seeking to terminate the Transaction Agreement; or |
• | if (i) any governmental entity of competent jurisdiction has issued a final and non-appealable order that is in effect and permanently restrains, enjoins or otherwise prohibits the consummation of the merger or the scheme or (ii) any governmental entity having jurisdiction over a party has adopted a law that is in effect that permanently makes illegal or otherwise permanently prohibits the consummation of the merger or the scheme (and such outcome was not principally caused by a material breach of any representation, warranty, covenant or agreement set forth in the Transaction Agreement by the party seeking to terminate the Transaction Agreement). In the case of clause (ii) above, if such law arises out of or relates to antitrust laws or investment screening laws, such law will only result in a right to terminate the Transaction Agreement to the extent the violation or contravention of such law as in effect would reasonably be expected to result in criminal liability to any person, personal liability to any director or officer of Allkem, Merger Sub, NewCo, Livent or any of their respective subsidiaries, or a material adverse effect on NewCo and its subsidiaries following the effective time. |
• | by Allkem pursuant to the Allkem Adverse Change Termination Right; |
• | by Livent pursuant to the Livent Change of Recommendation Termination Right or the Livent Intervening Event Termination Right; or |
• | (i) by either Livent or Allkem pursuant to the End Date Termination Right or the Livent Stockholder Approval Failure Termination Right, or by Allkem pursuant to the Allkem Material Breach Termination Right following an intentional and material breach of a covenant by Livent, (ii) prior to such termination but after the date of the Transaction Agreement, a bona fide Competing Proposal has been publicly made to Livent or any of its subsidiaries, has been made directly to the Livent stockholders generally or otherwise has become public or any person has publicly announced an intention (whether or not conditional) to make a bona fide Competing Proposal to Livent or, in the case of termination by Allkem pursuant to the Allkem Material Breach Termination Right, a Competing Proposal has been made publicly or privately to the Livent Board, and (iii) within 12 months after the date of a termination in either of the cases referred to in the preceding clauses (i) and (ii), Livent consummates a Competing Proposal or enters into a definitive agreement providing for a Competing Proposal (provided that solely for purposes of this bullet, all references to “20% or more” in the definition of “Competing Proposal” will be deemed to be references to “more than 50%”). |
• | by Livent pursuant to the Livent Adverse Change Termination Right (other than in the event such Allkem Change of Recommendation is due to an Independent Expert Event); |
• | by Allkem pursuant to the Allkem Change of Recommendation Termination Right, the Allkem Intervening Event Termination Right or, if applicable, the Allkem Independent Expert Event Termination Right; or |
• | (i) by either Livent or Allkem pursuant to the End Date Termination Right or the Allkem Shareholder Approval Failure Termination Right, or by Livent pursuant to the Livent Material Breach Termination Right following an intentional and material breach of a covenant by Allkem, (ii) prior to such termination but after the date of the Transaction Agreement, a bona fide Competing Proposal has been publicly made to Allkem or any of its subsidiaries, has been made directly to the Allkem shareholders generally or otherwise has become public or any person has publicly announced an intention (whether or not conditional) to make a bona fide Competing Proposal to Allkem or, in the case of termination by Livent pursuant to the Livent Material Breach Termination Right, a Competing Proposal has been made publicly or privately to the Allkem Board, and (iii) within 12 months after the date of a termination in either of the cases referred to in the preceding clauses (i) and (ii), Allkem consummates a Competing Proposal or enters into a definitive agreement providing for a Competing Proposal (provided that solely for purposes of this bullet, all references to “20% or more” in the definition of “Competing Proposal” will be deemed to be references to “more than 50%”). |
• | The accompanying notes to the unaudited pro forma condensed combined financial information; |
• | The separate audited financial statements of Livent as of and for the fiscal year ended December 31, 2022, and the related notes, included in Livent’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, incorporated by reference into this proxy statement/prospectus; |
• | The separate interim unaudited condensed consolidated financial statements of Livent as of and for the nine months ended September 30, 2023, and the related notes, included in Livent’s Quarterly Report on Form 10-Q for the period ended September 30, 2023, incorporated by reference into this proxy statement/prospectus; and |
• | The separate audited consolidated financial statements of Allkem as of and for the fiscal year ended June 30, 2023, and the related notes, included in this proxy statement/prospectus. |
• | Each holder of outstanding and unvested Allkem Performance Rights, whose role is not being made redundant through the execution of the transaction, will have their Allkem Performance Rights vest in the proportion determined by the Allkem Board provided that, in aggregate, no less than 60% and no more than 70% of the total number held by such Allkem employees will vest by no later than the date of scheme effectiveness. Each vested Allkem Performance Right will be exchanged for an Allkem Share prior to the Scheme Record Date and be eligible to receive the scheme consideration. The remaining unvested Allkem Performance Rights will lapse and, as soon as practicable following the transaction, NewCo will issue replacement awards to the prior holders which will (i) be substantially comparable in value to the corresponding lapsed Allkem Performance Rights as at the date of scheme effectiveness, (ii) be in respect of NewCo Shares and (iii) if the employment of a holder of a replacement right is terminated as a result of redundancy in the 12 months following the transaction, vest in full upon such termination. Each holder of outstanding Allkem Performance Rights whose role will be made redundant through the execution of the transaction will have up to 100% of their awards vested, as determined by the Allkem Board, by no later than the date of scheme effectiveness. Each vested Allkem Performance Right will be exchanged for an Allkem Share prior to the Scheme Record Date and be eligible to receive the scheme consideration. The remaining unvested Allkem Performance Rights will lapse. For purposes of the unaudited pro forma condensed combined financial information, all holders of outstanding Allkem Performance Rights are assumed to hold roles that are not being made redundant. |
• | Unvested Livent RSUs will be assumed by NewCo then vest on a pro rata basis based on the number of days elapsed from the commencement date of the vesting period to the date of the merger compared to the original vesting period, rounded down to the nearest whole share. Unvested Livent RSUs assumed by NewCo shall be subject to substantially the same terms and conditions as the previous Livent Shares except for the right to receive NewCo shares upon vesting. Vested Livent RSUs at the time of the merger, including those so vested on a pro rata basis, will be canceled in exchange for the right to receive the merger consideration of 2.406 NewCo Shares per Livent RSU, plus any cash consideration related to fractional shares. |
• | Livent PSUs will vest in full based on the achievement of the higher of target or actual performance. Vested Livent PSUs at the time of the merger will be canceled in exchange for the right to receive the merger consideration of 2.406 NewCo Shares per Livent RSU, plus any cash consideration related to fractional shares. |
• | All Livent Options will be assumed by NewCo at substantially the same terms and conditions as prior to the merger, provided that the number of shares exercisable by each option and the exercise price of each option will be adjusted by the Merger Exchange Ratio. |
• | Livent Director RSUs will vest in full immediately prior to the merger. At the time of the merger, the awards will be cancelled and converted into a right to receive cash per award equal to the higher of (i) the first available closing price of the NewCo Share and (ii) closing price per Livent Share, as reported in the NYSE, on the last trading day preceding the merger date. |
• | NewCo is a shell company and was formed in contemplation and for the purpose of completing the transaction; |
• | Livent initiated the negotiation of the transaction; |
• | The Chief Executive Officer and the Chief Financial Officer of Livent will continue as the Chief Executive Officer and Chief Financial Officer, respectively, of NewCo and Livent’s other executive officer, Ms. Sara Ponessa, General Counsel, will continue to perform the same role for NewCo; |
• | Under the NewCo articles of association, the Chief Executive Officer has the authority to select NewCo’s officers other than those required to be elected by the NewCo board of directors; |
• | The NewCo board of directors will be split evenly with six nominees from each of Livent and Allkem with equal voting rights, and matters on which the NewCo board of directors is deadlocked will not be approved (in this regard, the appointment of Mr. Peter Coleman, who is Allkem’s current Chairman, as the Chair of the NewCo board of directors did not impact the analysis because NewCo’s Chair will not have any tie-breaking or other special voting powers or any ability to affect the voting powers of the other NewCo directors under NewCo’s articles of association); |
• | There was an implied approximately 14% premium (measured as the difference between the agreed Merger Exchange Ratio and the implied merger exchange ratio based on the prices of Allkem Shares and Livent Shares, using volume weighted average share prices over one month from April 10, 2023 through May 9, 2023, the day immediately prior to the date of the Transaction Agreement) to Allkem shareholders; |
• | Notwithstanding that former shareholders of Allkem will own approximately 56% of the NewCo Shares (either directly or through CDIs) compared to Livent stockholders owning approximately 44%, on a fully diluted basis, the shareholders of NewCo will be diffuse with no holder or group of holders having a significant voting or minority ownership, and, as discussed above, the NewCo board of directors representing the shareholders will be split evenly with six nominees from each of Livent and Allkem, and each director (including the Chair) will have equal voting rights; and |
• | Livent had a similar total market capitalization to Allkem prior to the announcement of the transaction, notwithstanding Allkem’s larger size in terms of assets, earnings and revenues as of the date of this proxy statement/prospectus. |

• | The unaudited pro forma condensed combined statement of operations for the Pro Forma Interim Period has been prepared as if the transaction had occurred on January 1, 2022 and combines Livent’s unaudited condensed consolidated statement of operations for the nine months ended September 30, 2023 with Allkem’s unaudited interim consolidated income statement for the nine months ended June 30, 2023. Allkem’s unaudited interim consolidated income statement for the nine months ended June 30, 2023 is calculated as the audited consolidated statement of profit or loss for the year ended June 30, 2023, less the unaudited interim consolidated income statement for the three months ended September 30, 2022. Allkem’s unaudited interim consolidated income statement for the nine months ended June 30, 2023 was prepared by Allkem’s management for purposes of the unaudited pro forma condensed combined statement of operations and is not separately included in this proxy statement/prospectus since Allkem is not required to and does not publish quarterly financial statements. |
• | The unaudited pro forma condensed combined statement of operations for the Pro Forma Annual Period has been prepared as if the transaction had occurred on January 1, 2022 and combines Livent’s audited consolidated statement of operations for the fiscal year ended December 31, 2022 with Allkem’s unaudited consolidated statement of profit or loss for the twelve months ended December 31, 2022. Allkem’s unaudited consolidated statement of profit or loss for the twelve months ended December 31, 2022 is calculated as the audited consolidated statement of profit or loss for the year ended June 30, 2022, less the unaudited interim consolidated income statement for the six months ended December 31, 2021, plus the unaudited interim consolidated income statement for the six months ended December 31, 2022. |

(r) | Finance costs of $3.0 million related to a loss on current and non-current VAT recoveries and $0.1 million of accretion expenditure related to Allkem’s rehabilitation provision have been reclassified to cost of sales. |
a. | Allkem has designated certain financial assets to be measured at fair value through other comprehensive income (“FVOCI”). Under GAAP, those financial assets will be recognized at fair value through profit or loss (“FVTPL”). |
i. | Balance sheet impact: Cumulative losses of $6.4 million were reclassified from accumulated other comprehensive loss to retained earnings as of the Pro Forma Balance Sheet date. There were no changes to the carrying amount of the financial assets on the unaudited pro forma condensed combined balance sheet. |
ii. | Income statement impact: The amount reclassified from other comprehensive income to other loss / (gain) was a loss of $0.1 million and a loss of $2.2 million for the Pro Forma Interim Period and the Pro Forma Annual Period, respectively. |
b. | Allkem’s asset retirement obligations (“AROs” or rehabilitation provisions as disclosed in Allkem’s Financial Report for the Year Ended June 30, 2023 (the “Allkem 2023 Annual Report”)) were discounted using risk-free rates under IFRS. These obligations have been remeasured using a credit adjusted discount rate under GAAP, with the credit adjustment being specific to the entity with the AROs. The cash flows used for the measurement of Allkem’s ARO are probability weighted, representing cash outflows which are probable for each of Allkem’s applicable sites. After initial recognition and measurement of the AROs, any incremental liabilities incurred (or expected to be incurred) in subsequent periods are considered to be an additional “layer” of the original ARO. Each “layer” is initially measured at fair value. |
i. | Balance sheet impact: AROs included within other long-term liabilities decreased by $34.9 million and the related AROs included within property, plant and equipment decreased $34.6 million as of the Pro Forma Balance Sheet date. A corresponding adjustment to deferred taxes was made to decrease deferred income tax liabilities of $11.3 million. In addition, cumulative adjustments of an increase to retained earnings of $9.7 million and a decrease of $1.1 million of accumulated other comprehensive loss as of the Pro Forma Balance Sheet date were recorded. An increase in non-controlling interests of $3.0 million associated with these balance sheet adjustments was also recorded. |
ii. | Income statement impact: The change resulted in a decrease to depreciation of $0.1 million and nil recorded in cost of sales for the Pro Forma Interim Period and the Pro Forma Annual Period, respectively. |
c. | Allkem, in its capacity as a lessee, adopted a single model for lease accounting under IFRS and has remeasured its leases in accordance with GAAP. Under GAAP, Allkem has reclassified all of its leases as operating leases based on their contractual terms and conditions. The following adjustments have been made for Allkem’s operating leases under GAAP: |
i. | Balance sheet impact: |
A. | Right of use assets were increased by $3.1 million as of the Pro Forma Balance Sheet date and previously capitalized depreciation of $0.5 million was deducted from property, plant and equipment, due to different methods of depreciation for operating lease right of use assets under GAAP and the single lessee model under IFRS; |
B. | Cumulative adjustments relating to the balances of right of use assets and liabilities of $1.1 million were recognized directly as an increase in retained earnings as of the Pro Forma Balance Sheet date; and |
C. | An increase in deferred income tax liabilities of $0.9 million and an increase in non-controlling interests of $0.6 million associated with these balance sheet adjustments were recorded. |
ii. | Income statement impact: |
A. | Previously recognized finance costs of $3.8 million for the Pro Forma Interim Period and $5.2 million for the Pro Forma Annual Period were reclassified to cost of sales and $0.1 million of finance costs for both the Pro Forma Interim Period and the Pro Forma Annual Period were reclassified to selling, general and administrative expenses. These reclassifications were made based on the nature and use of the underlying leased assets; |
B. | In addition, a further reclassification of depreciation expense from cost of sales to selling, general and administrative expenses of $0.7 million for the Pro Forma Interim Period and $0.6 million for the Pro Forma Annual Period, was made based on the nature and use of the underlying leased assets; and |
C. | An additional impact of the adoption of GAAP from IFRS was a nil and $0.1 million reduction to cost of sales in the Pro Forma Interim Period and Pro Forma Annual Period and represents the difference in the method of depreciation for operating lease right of use assets under GAAP and the single lessee model under IFRS. |
d. | Allkem capitalizes exploration and evaluation (“E&E”) expenditure on an area of interest basis under the IFRS framework. Under GAAP, E&E expenditure is capitalized under a successful efforts basis, that is, when proven and probable reserves are established for the sites where E&E activities are being performed. E&E assets recognized as part of business combinations continue to be capitalized, which represents the majority of Allkem’s E&E assets from the Galaxy/Orocobre Merger in August 2021. |
i. | Balance sheet impact: An adjustment of $28.0 million recognized as a decrease in property, plant and equipment, net of accumulated depreciation and a decrease to retained earnings of $26.4 million has been recorded related to prior period amounts that were previously capitalized on the Pro Forma Balance Sheet. A corresponding adjustment of $8.4 million was recognized in current income taxes related to the decrease in deferred income tax liabilities of $9.8 million. A decrease in non-controlling interests of $0.2 million associated with these balance sheet adjustments was recorded. |
ii. | Income statement impact: E&E assets of $5.3 million and $3.6 million which were previously capitalized have been recognized as an expense within cost of sales for the Pro Forma Interim Period and the Pro Forma Annual Period, respectively. Incremental tax benefit of $1.4 million for the Pro Forma Interim Period and $1.3 million for the Pro Forma Annual Period related to the impact of the unaudited pro forma condensed combined statement of operations adjustment. |
e. | Allkem has not recognized any deferred tax assets in relation to its investment in the Toyotsu Lithium Corporation (“TLC”) based on the probability of realizing benefits associated with the deferred tax assets. |
i. | Balance sheet impact: Under GAAP, gross deferred tax assets of $0.8 million, with an offsetting valuation allowance of $0.8 million, were recognized as of the Pro Forma Balance Sheet date, resulting in a net nil impact on deferred income taxes. |
f. | Allkem has not recognized any deferred tax assets in relation to tax losses for its Canadian operations based on the likelihood of future profitability in that jurisdiction. |
i. | Balance sheet impact: Under GAAP, gross deferred tax assets of $16.2 million, with an offsetting valuation allowance of $16.2 million, were recognized as of the Pro Forma Balance Sheet date, resulting in a net nil impact on deferred income taxes. |
g. | Allkem acquired a mining tenement through an asset swap, with a net cash outflow of $0.4 million. The deferred tax implications of this asset swap were exempt for IFRS purposes. Under GAAP, the deferred tax implication of the asset acquisition has been recognized using the simultaneous equation method. |
i. | Balance sheet impact: Under GAAP, additional deferred tax liabilities of $10.5 million, with a corresponding increase to property, plant and equipment, were recognized as of the Pro Forma Balance Sheet date. |
h. | While not a difference between the GAAP and IFRS frameworks, Livent uses the first in first out (“FIFO”) method for inventory costing, while Allkem uses the weighted average cost (“WAC”) method resulting in a policy difference. |
i. | Balance sheet impact: |
A. | An increase of $8.5 million was recorded in accrued and other current liabilities as of the Pro Forma Balance Sheet date and a corresponding $8.5 million increase to Allkem’s investment in TLC as of the Pro Forma Balance Sheet date as a result of the use of FIFO which increased the cost of TLC inventory described in more detail in the income statement impact below. |
B. | An increase of $5.0 million was recorded in inventory as of the Pro Forma Balance Sheet date and a corresponding increase of $1.7 million in current income taxes was recorded as of the Pro Forma Balance Sheet date as a result of using FIFO which impacts the cost of inventory for Sales |
ii. | Income statement impact: |
A. | Under FIFO, the cost of TLC inventory increased by $8.5 million as of the Pro Forma Balance Sheet date and results in a corresponding reduction in TLC’s cost of sales of $8.5 million and $4.8 million for the Pro Forma Interim Period and Pro Forma Annual Period, respectively. The net flow on impact for Allkem is a reduction in its equity accounted share of the loss from the associate of $8.5 million for the Pro Forma Interim Period and $4.8 million for the Pro Forma Annual Period. The increase in cost of TLC’s inventory at the Pro Forma Balance Sheet date effects realized profits from the sale of inventory between TLC and Allkem. The reduction in Allkem’s equity accounted share of the loss from the associate of $8.5 million and $4.8 million resulted in an increase of $8.5 million and $4.8 million in Allkem’s elimination adjustment for unrealized profits from the sale of inventory between TLC and Allkem recorded in cost of sales for the Pro Forma Interim Period and the Pro Forma Annual Period, respectively. |
B. | Under FIFO, the cost of inventory for Sales De Jujuy and Mt Cattlin combined, decreased by $5.2 million and increased by $0.2 million for the Pro Forma Interim Period and Pro Forma Annual Period, respectively. Incremental tax expense of $1.8 million for the Pro Forma Interim Period and incremental tax benefit of $0.1 million for the Pro Forma Annual Period and an increase in income attributable to noncontrolling interests of $1.1 million for the Pro Forma Interim Period and $0.3 million for the Pro Forma Annual Period related to the net impact of this unaudited pro forma condensed combined statement of operations adjustment. |

(i) | As the calculation is deemed to reflect the capital increase of the accounting acquirer, the share price of Livent Shares is adjusted by dividing the share price of Livent Shares by the Merger Exchange Ratio (i.e., 2.406 NewCo Shares per Livent Share), or $12.96 divided by 2.406, resulting in $5.39, in order to reflect the value of Livent Shares that Allkem shareholders would receive if Livent were to issue its own shares. |
(ii) | As discussed in “—Description of the Transaction” above, certain Allkem Performance Rights will be replaced by NewCo’s equity awards with similar terms. Amount represents the estimated consideration attributable to pre-combination service for settlement or replacement of Allkem’s outstanding Allkem Performance Rights, specifically (A) the fair value related to Allkem Performance Rights vested but unexercised exchanged into an Allkem Share immediately prior to the transaction, (B) the fair value attributable to pre-combination services for unvested Allkem Performance Rights accelerated pursuant to the Transaction Agreement, and (C) the fair value attributable to pre-combination services for unvested Allkem Performance Rights replaced by NewCo’s equity awards with similar terms. The portion of the fair value of NewCo equity awards not included in consideration transferred represents compensation expense of the combined entity based on the vesting terms of the converted awards. |

(i) | Includes preliminary fair value of inventories totaling $335.1 million, of which $242.9 million is classified as current and $92.2 million is classified as non-current. Brine inventory is classified as non-current if the brine will not be processed and sold within 12 months after the balance sheet date. A 25% change in the valuation of inventories would cause a corresponding increase or decrease in the adjustment to cost of sales of approximately $0.4 million for the Pro Forma Interim Period and $27.9 million for the Pro Forma Annual Period. The fair value of the inventory is preliminary and is subject to change. The fair value of inventory was estimated using the comparative sales method, which relies on certain key inputs and judgments including expected sales price of the inventory, percentage complete of the work-in-process inventory, estimated costs of completion and disposal of the inventory, and forecasted profit margins earned on the sale of the inventory. Changes in these inputs could have a significant impact on the inventory valuation. The impact on cost of sales following the transaction may differ significantly between periods based upon the final value assigned for inventory. |
(ii) | Includes preliminary fair value of mineral rights totaling $2,876.0 million and non-mineral rights property, plant and equipment totaling $1,365.6 million. Mineral rights were identified for each of Allkem’s five primary mining locations and the assessed value for each right is inclusive of the fair value associated with the mine property as well as the fair value associated with any capitalized exploration and evaluation assets (as disclosed in the Allkem 2023 Annual Report). Fair value for the mineral rights by location were: Mt Cattlin - $25.0 million, James Bay - $1,051.0 million, Sal de Vida - $653.0 million, Cauchari - $295.0 million, and Olaroz - $852.0 million. Mineral rights, including evaluation and exploration assets, are classified within property, plant and equipment as mining properties on the unaudited condensed combined balance sheet. |

It is assumed that these costs will not affect the condensed combined statements of operations beyond twelve months after the closing date of the transaction. The balance excludes $45.2 million of estimated transaction costs to be incurred by Allkem as a result of the transaction, which were not reflected in the Allkem 2023 Annual Report. These costs will be recognized as an expense in Allkem’s pre-combination income statement and therefore they are reflected as a liability assumed by Livent, and do not impact the statement of operations of the combined entity. |

Costs for the nine months ended September 30, 2023 reflect the portion of the step-up in inventory classified as non-current and included in other assets on the unaudited condensed combined balance sheet expected to be sold in the nine months ended September 30, 2023. |
(ii) | Reflects the revised depreciation of property, plant and equipment assets arising on the acquisition of Allkem and is based on management’s preliminary estimate of useful lives and future production. Livent has historically depreciated all asset classes of property, plant and equipment on a straight-line basis. Allkem has historically depreciated their mining extraction equipment and mine properties using units of production (“UOP”) and uses a straight-line basis for all other asset classes. The mining extraction equipment and mine properties would be classified as separate asset classes for the combined entity and will continue to be depreciated using UOP on a go-forward basis. All other asset classes will use the straight-line depreciation method. |

(c) | Represents $83.3 million of transaction-related costs for the year ended December 31, 2022 that are not currently reflected in the historical consolidated financial statements of Livent or Allkem. Livent recognized transaction related costs of $2.9 million and $25.0 million in the Pro Forma Annual Period and Pro Forma Interim Period, respectively. Allkem recognized transaction related costs of $9.9 million in the Pro Forma Interim Period. It is assumed that these costs will not affect the condensed combined statements of operations beyond twelve months after the closing date of the transaction. |
(d) | To record the income tax impact of the pro forma adjustments based on the statutory tax rates of the jurisdictions in which the related pro forma adjustment is recorded. The effective tax rate of the combined company could be significantly different (either higher or lower) depending on post-transaction activities, including cash needs, the geographical mix of income and changes in tax law. Because the tax rates used for the pro forma financial information are estimated, the blended rate will likely vary from the actual effective rate in periods subsequent to completion of the transaction. This determination is preliminary and subject to change based upon the final determination of the fair value of the acquired assets and assumed liabilities. |
(e) | Represents the pro forma economic interest the noncontrolling shareholders hold in Allkem’s subsidiaries. The amount is determined by multiplying the applicable pro forma adjustments relevant to those subsidiaries by the noncontrolling interest. |

In connection with the transaction, certain Allkem Performance Rights held by Allkem employees will be converted into NewCo equity awards. At this time, management has completed a preliminary analysis related to eligible employees and vesting schedules to determine the impact to the diluted weighted average shares from the converted Allkem Performance Rights. The pro forma basic and diluted weighted average shares outstanding are as follows: |
(i) | Weighted average number of Livent Shares issued and outstanding, excluding treasury shares, as of September 30, 2023, which will be exchanged for NewCo Shares. |
(ii) | Weighted average number of Livent Shares issued and outstanding, excluding treasury shares, as of September 30, 2023, including Livent RSUs and Livent PSUs for which vesting will be accelerated pursuant to the transaction and will be exchanged for NewCo Shares. |

• | Water and Brine. Brine is extracted from wells in the salt lake (salar) and pumped to large scale evaporation ponds. The processing of brines consumes industrial water, which is extracted and treated to be used in processing and is then returned to the evaporation ponds after processing to recover residual lithium. |
• | Energy. Energy is generated by natural gas generators to power processes in the production plant and provide electricity. Diesel is used on site for machinery and the transport fleet. Allkem’s greatest source of energy is supplied by solar radiation which is used for concentrating brine in the evaporation ponds. |
• | Reagents. Lime, soda ash, and other reagents and CO2 are incorporated in the process to remove impurities and crystallize and purify lithium carbonate product. In terms of volume, lime and soda ash are the highest consumables. Lime is procured locally from various suppliers with a mixture of medium-term contracts with prices tied to key consumables and long-standing relationships. Soda ash is imported from different international suppliers with a mix of medium- or long-term contractual relationships. |
• | Water. Groundwater is sourced from a bore field, a decant return line from in pit tailings storage facility and rainwater tanks. Raw water is sourced from water bores and piped to either the raw water dam to be used in the processing plant or for use in dust suppression in mining operations. Rainwater is also captured and primarily used for drill rigs. |
• | Energy. Diesel is used for electricity generation and for the transport fleet, plant and machinery. Energy is used to treat water in a reverse osmosis plant for human consumption. |

In addition to Allkem’s stake in the Olaroz joint venture, Allkem also owns 100% of six properties immediately in the north of Olaroz, which properties’ mineral resources are reported on a 100% basis. |
• | The estimate is reported in-situ and exclusive of mineral reserves, where the lithium mass is representative of what remains in the reservoir after the LOM. To calculate mineral resources exclusive of mineral reserves, a direct correlation was assumed between proven reserves and measured resources, as well as probable reserves and indicated resources. Proven mineral reserves (from the point of reference of brine pumped to the evaporation ponds) were subtracted from measured mineral resources, and probable mineral reserves (from the point of reference of brine pumped to the evaporation ponds) were subtracted from indicated mineral resources. The average grade for measured and indicated resources exclusive of mineral reserves was calculated based on the remaining brine volume and lithium mass. |
• | An elevated lithium cut-off grade of 300 mg/l was utilized based on a projected price of $20,000 per metric ton LCE over the entirety of the LOM of 32 years. The average lithium grade of the measured and indicated mineral resources corresponds to 641 mg/l and represents the flux-weighted composite brine collected as brine is routed to the evaporation ponds. Extracted grades at individual production wells and the average mineral resources concentration are well above the 300 mg/l cut-off grade, demonstrating that there are reasonable prospects for economic extraction. |
• | The estimated economic cut-off grade utilized for resource reporting purposes is 300 mg/l lithium, based on the following assumptions: |
○ | A technical grade LCE price of $20,000/metric ton. |
○ | A calculated recovery factor for the salar operation over the span of LOM is 62%, equivalent to the assumed process recovery factor of 62%. |
○ | An average annual brine pumping rate of 600 L/s is assumed. |
○ | Cost estimates are based on a combination of fixed brine extraction, G&A and plant costs and variable costs associated with raw brine pumping rate or lithium production rate and capital costs. Average LOM operating cost is calculated at approximately $4,149/metric ton LCE. |

• | holders of CDIs are not able to vote personally as shareholders at a meeting of NewCo. Instead, holders of CDIs are provided with a voting instruction form which will enable them to instruct the Depositary Nominee in relation to the exercise of voting rights. In addition, a holder of CDIs is able to request the Depositary Nominee to appoint the CDI holder or a third party nominated by the CDI holder as its proxy so that the proxy so appointed may exercise the votes attaching to the NewCo Shares; and |

Subject to the provisions of the Jersey Companies Law and the NewCo articles of association, NewCo may purchase its own shares (including any redeemable shares) or CDIs and either cancel them or hold them as treasury shares. Under Jersey law, NewCo’s purchase of its own shares or CDIs must be sanctioned by a special resolution of NewCo’s shareholders. If the purchase is to be made on a stock exchange, the special resolution must specify the maximum number of shares or CDIs to be purchased, the maximum and minimum prices which may be paid, and the date on which the authority to purchase is to expire (which may not be more than five years after the date of the resolution). If the purchase is to be made other than on a stock exchange, the purchase must be made pursuant to a written purchase contract approved in advance by a resolution of shareholders. The shares being purchased do not carry the right to vote on the resolution sanctioning the purchase or approving that contract. However, the NewCo articles of association permit its board of directors to convert any of its shares into redeemable shares with the consent of the holder of such shares, and thus allow the board of directors to authorize share redemptions in this manner without a special resolution of NewCo’s shareholders. | |

Rights to Dividends | |||
| | ||
Section 170 of the DGCL provides that the directors of a corporation may declare and pay dividends upon the shares of its capital stock subject to certain limitations. | | | The NewCo board of directors may declare and pay any dividends from time to time as the NewCo board of directors may determine. The NewCo board of directors may rescind a decision to pay a dividend before the payment date in its sole discretion. The payment of a dividend does not require shareholder confirmation or approval at a general meeting of the shareholders. Holders of NewCo Shares are entitled to receive equally, on a per share basis, any dividends that may be declared on a per share basis as adjusted with reference to any portion of the share, which is not fully paid. The NewCo board of directors may direct that a dividend will be satisfied from any available source permitted by law, including wholly or partly by the distribution of assets, |
Livent | | | NewCo |
| | including paid-up shares or securities of another company. If, in the future, NewCo declares cash dividends, such dividends will be declared in U.S. dollars. The NewCo articles of association permits the NewCo board of directors to require that all dividend payments will be paid only through electronic transfer into an account selected by the shareholder rather than by a bank cheque. | |
| | ||
Appraisal Rights | |||
| | ||
In general under the DGCL, in connection with a merger or consolidation (subject to certain exceptions, such as that described below) stockholders will have appraisal rights in connection with such merger or consolidation. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation, as applicable, will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery. However, Livent stockholders are not entitled to appraisal rights under Section 262 of the DGCL in connection with the merger because Livent Shares are listed on the NYSE and holders of eligible shares of Livent are not required to receive consideration other than shares of NewCo, which are expected to be listed on the NYSE. | | | No appraisal rights are available to shareholders of a company organized under the laws of the Bailiwick of Jersey. |
| | ||
Disclosure of Interests | |||
| | ||
Holders of beneficial interests in Livent Shares must comply with the beneficial ownership disclosure obligations contained in section 13(d) of the Exchange Act and the rules promulgated thereunder. | | | Holders of beneficial interests in NewCo Shares must comply with the beneficial ownership disclosure obligations contained in section 13(d) of the Exchange Act and the rules promulgated thereunder. Under the NewCo articles of association, NewCo may, by written notice, require any person whom NewCo knows or has reasonable cause to believe to hold an interest in NewCo Shares or to have held an interest at any time during the three years prior, to confirm whether that is the case and give further information as to their interest as requested. Where a person fails to comply with such notice within the reasonable time period specified in the notice or has made a statement which is false or inadequate, then, unless the NewCo board of directors determines otherwise, the following restrictions will apply to the applicable shares and to any new shares issued in right of those shares for so long as such person remains in default under the notice: • no voting rights will be exercisable in respect of those shares; |

The Livent bylaws also provide that the board of directors or a committee of the board of directors may not nominate for election or reelection as director any candidate who has not agreed to tender, promptly following the meeting at which he or she is elected as director, an irrevocable resignation that will be effective upon (a) the failure to receive the required number of votes for reelection at the next annual meeting of stockholders at which he or she faces reelection, and (b) acceptance of such resignation by the board of directors. If an incumbent director nominee fails to receive the required number of votes for reelection, within 90 days after certificate of the election results, the nominating and corporate governance committee of the board of directors will recommend to the board of directors whether to accept or reject the resignation or whether other action should be taken and the board of directors will act on such committee’s recommendation. | | | irrevocable resignation that will be effective upon (i) the failure to receive the required number of votes for re-election at the next annual meeting of shareholders at which he or she faces re-election, and (ii) acceptance of such resignation by the NewCo board of directors. The NewCo articles of association provide that if an incumbent director does not receive the required number of votes for re-election, within 90 days after certification of the election results, a governance committee of the NewCo board of directors will recommend to the board whether to accept or reject the resignation or whether other action should be taken and the NewCo board of directors will act on such recommendation. Under the NewCo articles of association, all directors are subject to annual re-election by shareholders. Directors will hold office until the conclusion of the next annual general meeting following his or her appointment, unless such director is re-elected at the general meeting. Where the number of persons validly proposed for election or re-election as a director is greater than the number of directors to be elected, the persons receiving the most votes (up to the number of directors to be elected) will be elected as directors and an absolute majority of votes cast will not be a pre-requisite to the election of such directors. |
| | ||
Removal | |||
| | ||
Under the Livent bylaws and certificate of incorporation, and subject to certain stockholder rights stated therein, a director may only be removed for cause. | | | Under the NewCo articles of association, a director may only be removed from office by ordinary resolution of NewCo shareholders in a general meeting for cause, including, but not limited to: • the director’s conviction (with a plea of nolo contendere deemed to be a conviction) of a serious felony involving moral turpitude or a violation of U.S. federal or state securities law, but excluding a conviction based entirely on vicarious liability; or • the director’s commission of any material act of dishonesty (such as embezzlement) resulting or intended to result in material personal gain or enrichment of the director at the expense of NewCo or any subsidiary and which act, if made subject to criminal charges, would be reasonably likely to be charged as a felony. |

of the corporation and upon such information, opinions, reports and statements presented to the corporation by corporate officers, employees, committees of the board of directors or other persons as to matters such member reasonably believes are within such other person’s professional or expert competence, provided that such other person has been selected with reasonable care by or on behalf of the corporation. | | | • exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. Customary law is also an important source of law in the area of directors’ duties in Jersey as it expands upon and provides a more detailed understanding of the general duties and obligations of directors. The Bailiwick of Jersey courts view English common law as highly persuasive in this area. In summary, the following duties will apply as manifestations of the general fiduciary duty under the Jersey Companies Law: Duty to act in good faith A director has a duty to act in what he or she bona fide considers to be the best interests of the company. He or she must not act for any collateral purpose. In keeping with such a position of trust, the courts will give the individual director discretion to determine this, and are likely only to infer that he or she was not acting in good faith if no reasonable director could have believed that the course of action was in the best interests of the company. Generally, as with other fiduciary duties, the duty of good faith is owed by every director individually and not collectively as a board and is owed only to the company and not to any other person, be it another company or an individual. Duty to act with diligence A director will be responsible for the conduct of the company’s business and have a duty to exercise reasonable care, skill and diligence in doing so. Therefore the directors should keep fully informed as to the financial position of the company, and seek to attend board meetings and participate in the management of the company whenever possible. |
| | Duty to exercise powers for a proper purpose Even if directors are acting in good faith and in the interests of the company and its shareholders as a whole, they must nevertheless use their powers for the purposes for which they were conferred and not for any collateral purpose. Duty to account for profits Jersey law generally precludes a director from taking a personal profit from any opportunities arising from his |

1. | Subject to paragraph 4 of this Exhibit A, the Parties’ obligations with respect to the Scheme Implementation do not become binding unless and until satisfaction or, to the extent permitted by applicable Law, waiver by each of Anaconda and Lion on or before the Sanction Date of the following conditions: |
(a) | as at 8:00 a.m. AWST on the Sanction Date, each of the conditions set out in this Exhibit A (other than the conditions in paragraph 1(b) and paragraph 1(c) of this Exhibit A) has been satisfied or waived (where permitted); |
(b) | the approval by the Court (or any court of competent jurisdiction on appeal therefrom) (without material modification) of the Scheme pursuant to Section 411(4)(b) of the Australian Act; |
(c) | the lodging by Anaconda of an office copy of the Court approving the Scheme under Section 411(4)(b) of the Australian Act; |
(d) | the Merger Closing shall be capable of occurring, and would reasonably be expected to occur, as promptly as practicable following the Scheme Implementation in accordance with the Steps Plan; |
(e) | the Anaconda Shareholder Approval being duly obtained at the Scheme Meeting (or at any adjournment or postponement thereof, in each case at which a vote on such approval was taken); |
(f) | the Lion Stockholder Approval being duly obtained at the Lion Special Meeting (or at any adjournment or postponement thereof, in each case at which a vote on such approval was taken); |
(g) | (i) the NYSE having approved the listing of the New Topco Shares to be issued to the holders of Lion Shares and the New Topco Shares, including New Topco Shares underlying the CDIs, to be issued to holders of Anaconda Shares pursuant to the Scheme and the Merger, subject to official notice of issuance, and (ii) ASX having provided approval for the admission of New Topco as a foreign exempt listing to the official list of ASX and the approval for official quotation of the CDIs, whether or not such approval is subject to conditions; |
(h) | all applicable Governmental Consents under the respective Antitrust Laws and the Investment Screening Laws of the jurisdictions set forth in Exhibit B on any terms described therein (as the same may be amended with the written consent of Anaconda and Lion) with respect to the Scheme and the Merger shall have been obtained or made (as applicable) and remain in full force and effect and all applicable waiting periods (including any extensions by agreement or operation of law) applicable to the Scheme and the Merger with respect thereto shall have expired, lapsed or been terminated (as applicable); |
(i) | the Form S-4 shall have become effective under the Securities Act and shall not be the subject of any stop order (which has not been withdrawn) or Proceedings initiated by the SEC seeking any stop order; |
(j) | (i) no Governmental Entity of a competent jurisdiction shall have issued any Order (whether temporary, preliminary or permanent) that is in effect and restrains, enjoins or otherwise prohibits the consummation of the Merger or the Scheme and (ii) no Governmental Entity having jurisdiction over any Party shall have adopted any Law that is in effect and makes consummation of the Merger or the Scheme illegal or otherwise prohibited (it being understood that if any such Law arises out of or relates to Antitrust Laws or Investment Screening Laws, the presence of such Law will only be a failure to meet a condition under this paragraph 1(j) of this Exhibit A to the extent it would constitute a Material Restraint); |
(k) | as at 8:00 a.m. AWST on the Sanction Date, neither the Agreement nor the Deed Poll having been terminated in accordance with its terms. |
2. | Subject to paragraph 5 of this Exhibit A, Anaconda’s obligations with respect to the Scheme Implementation will also be conditional upon the satisfaction or, to the extent permitted by applicable Law, waiver by Anaconda on or before the Sanction Date of the following conditions: |
(a) | (i) the representations and warranties of Lion set forth in Section 3.2(a), Section 3.2(b), Section 3.2(c), Section 3.2(f), Section 3.2(g) and Section 3.2(h) (in the case of Section 3.2(f), Section 3.2(g) and Section 3.2(h), only as applied to Lion and not Lion Subsidiaries) shall be true and correct, subject only to de minimis inaccuracies, (A) on the date of this Agreement and (B) at the Sanction Date as though made |
(b) | Each of Lion and the New Topco Parties shall have in all material respects performed the obligations and complied with the covenants required by the Agreement to be performed or complied with by it prior to the Sanction Date; |
(c) | Lion shall have delivered to Anaconda a certificate, dated as of the Sanction Date and signed by the Chief Executive Officer of Lion, certifying on behalf of Lion to the effect that the conditions set forth in paragraphs 2(a) and 2(b) of this Exhibit A have been satisfied; |
(d) | there shall not have been any Lion Material Adverse Effect; |
(e) | the Independent Expert shall have issued the IER, which concludes that the Scheme is in the best interest of Anaconda Shareholders and the Independent Expert does not change, withdraw or qualify its conclusion in any written update to its IER or withdraw the IER; and |
(f) | Anaconda shall have received confirmation (verbal or otherwise) from the ATO that either (1) there are no material impediments to or material issues to be resolved which may prevent the ATO from issuing the ATO Class Ruling or (2) the ATO is prepared to issue the ATO Class Ruling, in a form and substance satisfactory to Anaconda (acting reasonably), confirming that qualifying Australian resident Anaconda Shareholders will be eligible to choose rollover relief to the extent to which they receive New Topco Shares or CDIs in exchange for their Anaconda Shares in connection with the Scheme. For the avoidance of doubt, should an ATO Class Ruling not be available for all qualifying Australian resident Anaconda Shareholders, an ATO Class Ruling that includes (or would include, when issued) a confirmation that qualifying Australian resident shareholders who hold their shares on capital account are eligible to claim rollover relief will be acceptable to Anaconda. |
3. | Subject to paragraph 6 of this Exhibit A, Lion’s and New Topco’s obligations with respect to the Scheme Implementation will also be conditional upon the satisfaction or, to the extent permitted by applicable Law, waiver by Lion on or before the Sanction Date of the following conditions: |
(a) | (i) the representations and warranties of Anaconda set forth in Section 4.2(a), Section 4.2(c), Section 4.2(d) and Section 4.2(e) (in the case of Section 4.2(c), Section 4.2(d) and Section 4.2(e), only as applied to Anaconda and not Anaconda Subsidiaries) shall be true and correct, subject only to de minimis inaccuracies, (A) on the date of this Agreement and (B) at the Sanction Date as though made on the Sanction Date (in each case except to the extent that any such representation and warranty speaks as of a particular date, in which case such representation and warranty shall be so true and correct as of such date); (ii) the representations and warranties of Anaconda set forth in (x) Section 4.10(a) shall be true and correct in all respects and (y) the first sentence of Section 4.1, Section 4.2(b), Section 4.2(c), Section 4.2(d), Section 4.2(e), Section 4.2(f), Section 4.3(a), Section 4.16 and Section 4.19 (in the case of Section 4.2(c), |
(b) | Anaconda shall have in all material respects performed the obligations and complied with the covenants required by the Agreement to be performed or complied with by it prior to the Sanction Date; |
(c) | Anaconda shall have delivered to Lion a certificate, dated as of the Sanction Date and signed by the Chief Executive Officer of Anaconda, certifying on behalf of Anaconda to the effect that the conditions set forth in paragraphs 3(a) and 3(b) of this Exhibit A have been satisfied; |
(d) | there shall not have been any Anaconda Material Adverse Effect; and |
(e) | Lion shall have sought and received an opinion of Davis Polk & Wardwell LLP, or, if Davis Polk & Wardwell LLP is unable or unwilling to provide such opinion, Sidley Austin LLP (whichever such firm delivers such opinion, “Company Tax Counsel”), dated as of the Sanction Date, in form and substance reasonably satisfactory to Lion, to the effect that, on the basis of facts, representations and assumptions set forth or referred to in such opinion and as of the date thereof, (i) either (A) the Merger should qualify as a “reorganization” under Section 368(a) of the Code or (B) the Merger and the Scheme, taken together, should qualify as an exchange described in Section 351(a) of the Code, and (ii) the transfer of Lion Eligible Shares by Lion Stockholders pursuant to the Merger (other than by any Lion Stockholder who is a U.S. person and would be a “five-percent transferee shareholder” (within the meaning of Treasury Regulations Section 1.367(a)-3(c)(5)(ii)) of New Topco following the Merger that does not enter into a five-year gain recognition agreement in the form provided in Treasury Regulations Section 1.367(a)-8(c)) should qualify for an exception to Section 367(a)(1) of the Code. In rendering such opinion, Company Tax Counsel may rely on the tax representation letters provided for in Section 6.13(c), and such other information provided to it by Lion, New Topco and/or Anaconda for purposes of rendering such opinion. |
4. | Anaconda and Lion reserve the right (but shall be under no obligation) to waive (to the extent permitted by applicable Law), in whole or in part, all or any of the conditions in paragraph 1 of this Exhibit A (provided that each Party agrees to any such waiver). |
5. | Anaconda reserves the right (but shall be under no obligation) to waive, in whole or in part, to the extent permitted by applicable Law, all or any of the conditions in paragraph 2. |
6. | Lion reserves the right (but shall be under no obligation) to waive, in whole or in part, to the extent permitted by applicable Law, all or any of the conditions in paragraph 3. |

(a) | Subject to article 2.15(e), upon being entered in the register of members as the holder of a share, a member is entitled: |
(1) | without payment, to one certificate for all the shares of each class held by that member (and, upon transferring a part of the member’s holding of shares of any class, to a certificate for the balance of that holding); and |
(2) | upon payment of such reasonable sum as the directors may determine for every certificate after the first, to several certificates each for one or more of that member’s shares. |
(b) | Every certificate shall specify the number, class and distinguishing numbers (if any) of the shares to which it relates and whether they are fully paid or partly paid up. A certificate may be executed under seal or executed in such other manner as the directors determine and the Companies Law permits. |
(c) | The Company shall not be bound to issue more than one certificate for shares held jointly by several persons and delivery of a certificate for a share to one joint holder shall be a sufficient delivery to all of them. |

(f) | Following a written request at any time from a member to the Company requesting a share certificate in respect of shares held by that member, the Company shall, within two (2) months of receipt by the Company of that written request, complete and have ready for delivery the certificate of such shares in respect of which the request was made, unless the conditions of allotment of the shares otherwise provide. |
Calls, forfeiture, indemnities, lien and surrender |
Calls |
(a) | Subject to the terms on which any shares are issued, the Board may: |
(1) | make calls on the members for any amount unpaid on their shares which is not by the terms of issue of those shares made payable at fixed times; and |
(2) | on the issue of shares, differentiate between members as to the amount of calls to be paid and the time for payment. |
(b) | The Board may require a call to be paid by instalments. |

(g) | A call is valid even if a member for any reason does not receive notice of the call. |
(h) | If an amount called on a share is not paid in full by the time specified for payment, the person who owes the amount must pay: |
(1) | interest on the unpaid part of the amount from the date payment is due to the date payment is made, at a rate determined under article 3.7; and |
(2) | any costs, expenses or damages the Company incurs due to the failure to pay or late payment. |
(i) | Any amount unpaid on a share that, by the terms of issue of the share, becomes payable on issue or at a fixed date: |
(1) | is treated for the purposes of these articles as if that amount were payable under a call duly made and notified; and |
(2) | must be paid on the date on which it is payable under the terms of issue of the share. |
(j) | The Board may, to the extent the law permits, waive or compromise all or part of any payment due to the Company under the terms of issue of a share or under this article 3.1. |
Proceedings to recover calls |
(a) | In a proceeding to recover a call, or an amount payable due to the failure to pay or late payment of a call, proof that: |
(1) | the name of the defendant is entered in the register as the holder or one of the holders of the share on which the call is claimed; |
(2) | the resolution making the call is recorded in the minute book; and |
(3) | notice of the call was given to the defendant complying with these articles, |
(b) | In article 3.2(a), defendant includes a person against whom the Company alleges a set-off or counterclaim, and a proceeding to recover a call or an amount is to be interpreted accordingly. |
Payments in advance of calls |
(a) | The Board may accept from a member the whole or a part of the amount unpaid on a share even though no part of that amount has been called. |
(b) | The Board may authorise payment by the Company of interest on an amount accepted under article 3.3(a), until the amount becomes payable, at a rate agreed between the Board and the member paying the amount. |
(c) | The Board may repay to a member any amount accepted under article 3.3(a). |
Forfeiting partly paid shares |
(a) | If a member fails to pay the whole of a call or an instalment of a call by the time specified for payment, the Board may serve a notice on that member: |
(1) | requiring payment of the unpaid part of the call or instalment, together with any interest that has accrued and all costs, expenses or damages that the Company has incurred due to the failure to pay; |
(2) | specifying a further time (at least fourteen (14) days after the date of the notice) by which, and the manner in which, the amount payable under article 3.4(a)(1) must be paid; and |
(3) | stating that if the whole of the amount payable under article 3.4(a)(1) is not paid by the time and in the manner specified, the shares on which the call was made will be liable to be forfeited. |

(2) | an entry of the forfeiture, with the date, must be made in the register of members. |
(e) | Failure to give the notice or to make the entry required under article 3.4(d) does not invalidate the forfeiture. |
(f) | A forfeited share becomes the property of the Company and the Board may sell, reissue or otherwise dispose of the share as it thinks fit and, in the case of reissue or other disposal, with or without crediting as paid up any amount paid on the share by any former holder. |
(g) | A person whose shares have been forfeited ceases to be a member as to the forfeited shares, but must, unless the Board decides otherwise, pay to the Company: |
(1) | all calls, instalments, interest, costs, expenses and damages owing on the shares at the time of the forfeiture; and |
(2) | interest on the unpaid part of the amount payable under article 3.4(g)(1), from the date of the forfeiture to the date of payment, at a rate determined under article 3.7. |
(h) | The forfeiture of a share extinguishes all interest in, and all claims and demands against the Company relating to, the forfeited share and, subject to article 3.6(h), all other rights attached to the share. |
(i) | The Board may: |
(1) | exempt a share from all or part of this article 3.4; |
(2) | waive or compromise all or part of any payment due to the Company under this article 3.4; and |
(3) | before a forfeited share has been sold, reissued or otherwise disposed of, cancel the forfeiture on the conditions it decides. |
Lien on shares |
(a) | The Company has a first lien on: |
(1) | each partly paid share for all unpaid calls and instalments due on that share; and |
(2) | each share for any amounts the Company is required by law to pay and has paid in respect of that share. |
(b) | The Company’s lien on a share extends to all dividends, interest and other amounts payable on the share and to the proceeds of sale of the share. |
(c) | The Board may sell a share on which the Company has a lien as it thinks fit where: |
(1) | an amount for which a lien exists under this article 3.5 is presently payable; and |
(2) | the Company has given the registered holder a written notice, at least fourteen (14) days before the date of the sale, stating and demanding payment of that amount. |
(d) | The Board may do anything necessary or desirable to protect any lien, charge or other right to which the Company is entitled under these articles or a law. |
(e) | When the Company registers a transfer of shares on which the Company has a lien without giving the transferee notice of its claim, the Company’s lien is released so far as it relates to amounts owing by the transferor or any predecessor in title. |
(f) | The Board may: |
(1) | exempt a share from all or part of this article 3.5; and |
(2) | waive or compromise all or part of any payment due to the Company under this article 3.5. |
Sale, reissue or other disposal of shares by the Company |
(a) | A reference in this article 3.6 to a sale of a share by the Company is a reference to any sale, reissue or other disposal of a share under article 3.4(f) or article 3.5(c). |
(b) | When the Company sells a share, the Company may: |
(1) | receive the purchase money or consideration given for the share; |
(2) | effect a transfer of the share or execute or appoint a person to execute, on behalf of the former holder, a transfer of the share; and |
(3) | register as the holder of the share the person to whom the share is sold. |
(c) | A person to whom the Company sells shares need not take any steps to investigate the regularity or validity of the sale, or to see how the purchase money or consideration on the sale is applied. That person’s title to the shares is not affected by any irregularity by the Company in relation to the sale. A sale of the share by the Company is valid even if a Transmission Event occurs to the member before the sale. |
(d) | The only remedy of a person who suffers a loss because of a sale of a share by the Company is a claim for damages against the Company, but the Company shall not be liable for a loss caused by the price at which the shares are sold in good faith. |
(e) | The proceeds of a sale of shares by the Company must be applied in paying: |
(1) | first, the expenses of the sale; |
(2) | secondly, all amounts payable (whether presently or not) by the former holder to the Company, |
(f) | Until the proceeds of a sale of a share sold by the Company are claimed or otherwise disposed of according to law, the Board may invest or use the proceeds in any other way for the benefit of the Company. |
(g) | The Company is not required to pay interest on money payable to a former holder under this article 3.6. |
(h) | On completion of a sale, reissue or other disposal of a share under article 3.4(f), the rights which attach to the share which were extinguished under article 3.4(h) revive. |
(i) | A written statement by a director or secretary of the Company that a share in the Company has been: |
(1) | duly forfeited under article 3.4(b); |
(2) | duly sold, reissued or otherwise disposed of under article 3.4(f); or |
(3) | duly sold under article 3.5(c), |
Interest payable by member |
(a) | For the purposes of articles 3.1(h)(1) and 3.4(g)(2), the rate of interest payable to the Company is: |
(1) | if the Board has fixed a rate, that rate; or |
(2) | in any other case, a rate per annum 2% higher than the rate prescribed in respect of unpaid judgments in the Royal Court of Jersey. |
(b) | Interest accrues daily and may be capitalised monthly or at such other intervals the Board decides. |
Distributions |
Dividends |
(a) | Subject to each Statement of Rights and the provisions of the Companies Law, the Board may pay any dividends from time to time as the Board may determine, including any interim dividends. |
(b) | The Board may rescind a decision to pay a dividend, before the payment date in its sole discretion. |
(c) | The Board may pay any dividend required to be paid under the terms of issue of a share. |
(d) | The Board may pay half-yearly, quarterly or at other suitable intervals to be settled by them any dividend which may be payable at a fixed rate. |
(e) | Paying a dividend does not require confirmation or approval at a general meeting. |
(f) | Subject to any rights or restrictions attached to any shares or class of shares: |
(1) | all dividends must be paid equally on all shares, except that a partly paid share confers an entitlement only to the proportion of the dividend which the amount paid (not credited) on the share is of the total amounts paid and payable (excluding amounts credited); |
(2) | for the purposes of article 4.1(f)(1), unless the Board decides otherwise, an amount paid on a share in advance of a call is to be taken as not having been paid until it becomes payable; and |
(3) | interest is not payable by the Company on any dividend or any amounts payable therewith. |
(g) | The Board may fix a record date for a dividend. |
(h) | A dividend in respect of a share must be paid, subject to the rules of any Designated Stock Exchange (including any rules relating to the settlement of transfers of securities), to the person who is registered, or entitled under articles 5.1, 5.2 and 5.3 to be registered, as the holder of the share: |
(1) | where the Board has fixed a record date in respect of the dividend, on that date; or |
(2) | where the Board has not fixed a record date in respect of that dividend, on the date fixed for payment of the dividend, |
(i) | When resolving to pay a dividend, the Board may direct payment of the dividend from any available source permitted by law, including: |
(1) | wholly or partly by the distribution of specific assets, including paid-up shares or other securities of the Company or of another body corporate, either generally or to specific members; and |
(2) | to particular members wholly or partly out of any particular fund or reserve or out of profits derived from any particular source, and to the other members wholly or partly out of any other particular fund or reserve or out of profits derived from any other particular source. |
(j) | Where a person is entitled to a share because of a Transmission Event, the Board may, but need not, retain any dividends payable on that share until that person becomes registered as the holder of that share or transfers it. |
(k) | The Board may retain from any dividend payable to a member any amount presently payable by the member to the Company and apply the amount retained to the amount owing. |
(l) | The Board may decide the method of payment of any dividend or other amount in respect of a share. Different methods of payment may apply to different members or groups of members (such as overseas members). Without limiting any other method of payment which the Company may adopt, payment in respect of a share may be made: |
(1) | by such electronic or other means approved by the Board directly to an account (of a type approved by the Board) nominated in writing by the member or the joint holders; or |
(2) | by cheque sent to the address of the member shown in the register of members or, in the case of joint holders, to the address shown in the register of members of any of the joint holders, or to such other address as the member or any of the joint holders in writing direct. |
(m) | A cheque sent under article 4.1(l): |
(1) | may be made payable to bearer or to the order of the member to whom it is sent or any other person the member directs; and |
(2) | is sent at the member’s risk. |
(n) | If the Board decides that payments will be made by electronic transfer into an account (of a type approved by the Board) nominated by a member, but no such account is nominated by the member or an electronic transfer into a nominated account is rejected or refunded, the Company may credit the amount payable to an account of the Company to be held until the member nominates a valid account. |
(o) | Where a member does not have a registered address or the Company believes that a member is not known at the member’s registered address or cheques have been returned undelivered or other payment methods have failed on more than one occasion, the Company may credit an amount payable in respect of the member’s shares to an account of the Company to be held until the member claims the amount payable or nominates a valid account. |
(p) | An amount credited to an account under articles 4.1(n) or 4.1(o) is to be treated as having been paid to the member at the time it is credited to that account. The Company will not be a trustee of the money and no interest will accrue on the money. The money may be used for the benefit of the Company until claimed or otherwise disposed of according to applicable law. |
(q) | If a cheque for an amount payable under article 4.1(l) is not presented for payment for at least eleven (11) calendar months after issue or an amount is held in an account under articles 4.1(n) or 4.1(o) for at least eleven (11) calendar months, the Board may stop payment on the cheque and invest or otherwise make use of the amount for the benefit of the Company until claimed or otherwise disposed of according to applicable law. |
(r) | A dividend that remains unclaimed for a period of ten (10) years after it became due for payment shall be forfeited to, and shall cease to remain owing by, the Company. |
(s) | Provided the directors act reasonably and in accordance with the Companies Law, they shall not incur any personal liability to the holders of shares conferring a preference for any damage that they may suffer by reason of the payment of an interim dividend on any shares having deferred or non-preferred rights. |
Capitalising profits |
(a) | Subject to: |
(1) | any rights or restrictions attached to any shares or class of shares; and |
(2) | any special resolution of the Company; |
(3) | forming part of the undivided profits of the Company; |
(4) | representing profits arising from an ascertained accretion to capital or a revaluation of the assets of the Company; |
(5) | arising from the realisation of any assets of the Company; or |
(6) | otherwise available for distribution as a dividend. |
(b) | The Board may resolve that all or any part of the capitalised amount is to be applied: |
(1) | in paying up in full, at an issue price decided by the Board, any unissued shares in or other securities of the Company; |
(2) | in paying up any amounts unpaid on shares or other securities held by the members; |
(3) | partly as specified in article 4.2(b)(1) and partly as specified in article 4.2(b)(2); or |
(4) | any other method permitted by law. |
(c) | Articles 4.1(f), 4.1(g), 4.1(h), and 4.1(s) apply, so far as they can and with any necessary changes, to capitalising an amount under this article 4.2 as if references in those articles to: |
(1) | a dividend were references to capitalising an amount; and |
(2) | a record date were references to the date the Board resolves to capitalise the amount under this article 4.2. |
(d) | Where the terms of options (existing at the date the resolution referred to in article 4.2(b) is passed) entitle the holder to an issue of bonus shares under this article 4.2, the Board may in determining the number of unissued shares to be so issued, allow in an appropriate manner for the future issue of bonus shares to options holders. |
Ancillary powers |
(a) | To give effect to any resolution to reduce the capital of the Company, to satisfy a dividend as set out in article 4.1(i)(1) or to capitalise any amount under article 4.2, the Board may settle as it thinks expedient any difficulty that arises in making the distribution or capitalisation and, in particular: |
(1) | make cash payments in cases where members are entitled to fractions of shares or other securities; |
(2) | decide that amounts or fractions of less than a particular value decided by the Board may be disregarded to adjust the rights of all parties; |
(3) | fix the value for distribution of any specific assets; |
(4) | pay cash or issue shares or other securities to any member to adjust the rights of all parties; |
(5) | vest any of those specific assets, cash, shares or other securities in a trustee on trust for the persons entitled to the distribution or capitalised amount; and |
(6) | authorise any person to make, on behalf of all the members entitled to any specific assets, cash, shares or other securities as a result of the distribution or capitalisation, an agreement with the Company or another person which provides, as appropriate, for the distribution or issue to them of shares or other securities credited as fully paid up or for payment by the Company on their behalf of the amounts or any part of the amounts remaining unpaid on their existing shares or other securities by applying their respective proportions of the amount resolved to be distributed or capitalised. |
(b) | Any agreement made under an authority referred to in article 4.3(a)(6) is effective and binds all members concerned. |
(c) | If a distribution, transfer or issue of specific assets, shares or securities to a particular member or members is, in the Board’s discretion, considered impracticable or would give rise to parcels of securities that do not constitute a marketable parcel, the Board may make a cash payment to those members or allocate the assets, shares or securities to a trustee to be sold on behalf of, and for the benefit of, those members, instead of making the distribution, transfer or issue to those members. Any proceeds receivable by members under this article 4.3(c) will be net of expenses incurred by the Company and trustee in selling the relevant assets, shares or securities. |
(d) | If the Company distributes to members (either generally or to specific members) securities in the Company or in another body corporate or trust (whether as a dividend or otherwise and whether or not for value), each of those members appoints the Company as such member’s agent to do anything needed to give effect to that distribution, including agreeing to become a member of that other body corporate. |
Reserves |
(a) | The Board may set aside out of the Company’s profits any reserves or provisions it decides. |
(b) | The Board may appropriate to the Company’s profits any amount previously set aside as a reserve or provision. |
(c) | Setting aside an amount as a reserve or provision does not require the Board to keep the amount separate from the Company’s other assets or prevent the amount being used in the Company’s business or being invested as the Board decides. |
Carrying forward profits |
Transfer of shares |
Form of transfer |
(a) | Subject to the following articles about the transfer of shares, a member may transfer any certificated shares or, Uncertificated shares in accordance with the CREST Order, to another person by completing an instrument of transfer, in a common form or in a form approved by the directors, executed: |

(b) | The Board may, in its absolute discretion, refuse to register any instrument of transfer of a certificated share: |
(1) | which is not fully paid up but, in the case of a class of shares which has been admitted to trading on the Designated Stock Exchange, not so as to prevent dealings in those shares from taking place on an open and proper basis; |
(2) | on which the Company has a lien; or |
(3) | as otherwise required by applicable law. |
(c) | The Board may also refuse to register any instrument of transfer of a certificated share unless it is: |
(1) | left at the registered office of the Company, or at such other place as the Board may decide, for registration; |
(2) | accompanied by the certificate for the shares to be transferred and such other evidence (if any) as the Board may reasonably require to prove the title of the intending transferor or his right to transfer the shares; and |
(3) | in respect of only one class of shares. |

(a) | Subject to article 5.7(c), where a member dies, the only persons the Company will recognise as having any title to the member’s shares or any benefits accruing on those shares are: |
(1) | where the deceased was a sole holder, the legal personal representative of the deceased; and |
(2) | where the deceased was a joint holder, the survivor or survivors. |
(b) | Article 5.7(a) does not release the estate of a deceased member from any liability on a share, whether that share was held by the deceased solely or jointly with other persons. |
(c) | The Board may register a transfer of shares signed by a member before a Transmission Event even though the Company has notice of the Transmission Event. |
(d) | A person who becomes entitled to a share because of a Transmission Event may, on producing such evidence as the Board requires to prove that person’s entitlement to the share, choose: |
(1) | to be registered as the holder of the share by signing and giving the Company a written notice stating that choice; or |
(2) | to nominate some other person to be registered as the transferee of the share by executing or effecting in some other way a transfer of the share to that other person. |
(e) | The provisions of these articles concerning the right to transfer shares and the registration of transfers of shares apply, so far as they can and with any necessary changes, to a notice or transfer under article 5.7(d) as if the relevant Transmission Event had not occurred and the notice or transfer were executed or effected by the registered holder of the share. |
(f) | Where two (2) or more persons are jointly entitled to a share because of a Transmission Event they will, on being registered as the holders of the share, be taken to hold the share as joint tenants and article 2.13 will apply to them. |
Disclosure of interests |
Tracing notices |
(a) | The Company may give notice to any person whom the Company knows or has reasonable cause to believe: |
(1) | to hold an interest (as defined in article 6.2(i)(4)) in the Company’s shares (of a class of shares admitted to trading); or |

(c) | The notice may require the person to whom it is addressed to give particulars of the person’s own present or past interest in the Company’s shares held by such person at any time during the three (3) year period mentioned above. |
(d) | The notice may require the person to whom it is addressed, where: |
(1) | such person’s interest is a present interest and another interest in the shares subsists, or |
(2) | another interest in the shares subsisted during the three (3) year period mentioned above at a time when such person’s interest subsisted, to give, to the best of such person’s knowledge, such particulars with respect to that other interest as are required by the notice. |
(e) | The particulars referred to in articles 6.1(c) and 6.1(d) include: |
(1) | the identity of any person who holds an interest in the shares in question; and |

(f) | The notice may require the person to whom it is addressed, where the person’s interest is a past interest, to give (to the best of such person’s knowledge) particulars of the identity of the person who held that interest immediately upon the person ceasing to hold it. |

Failure to Respond |
(a) | If a member, or any other person appearing to have an interest in shares held by that member, has been given a notice under article 6.1 and has failed in relation to any shares (the Default Shares) to give the Company the information thereby required within three (3) Business Days from the time reasonably specified in the notice, the following sanctions shall apply, unless the Board otherwise determines in relation to the Default Shares: |
(1) | the member shall not be entitled in respect of the Default Shares to be present or to vote (either in person or by representative or proxy) at any general meeting or at any separate meeting of the holders of any class of shares or on any poll, or to exercise any other right conferred by membership in respect of the Default Shares in relation to any such meeting or poll; |
(2) | any dividend (or other distribution) payable in respect of the Default Shares shall be withheld by the Company (without interest) and the member shall not be entitled to elect to receive shares instead of any such dividend (or other distribution); and |
(3) | no transfer, other than an excepted transfer, of any shares held by the member may be registered unless: |
(i) | the member is not in default as regards supplying the information required; and |
(ii) | the member proves to the satisfaction of the Board that no person in default as regards supplying such information has an interest in any of the shares the subject of the transfer. |
(b) | In support of article 6.2(a), the Board may, at any time while sanctions under article 6.2(a) apply in relation to any shares, effect a transfer of the shares (or any interest in them) in favour of such nominee as specified by the Board. |
(c) | Where any person appearing to have an interest in the Default Shares has been duly served with a notice or copy thereof and the Default Shares which are the subject of such notice are held by a person holding shares or rights or interests in shares in the Company on a nominee basis who has been determined by the Company to be an approved nominee (an Approved Nominee): |
(1) | the provisions of this article 6 shall be treated as applying only to such Default Shares held by the Approved Nominee and not (insofar as such person’s apparent interest is concerned) to any other shares held by the Approved Nominee; and |
(2) | where the member upon whom a default notice is served is an Approved Nominee acting in its capacity as such, the obligations of the Approved Nominee as a member of the Company are limited to disclosing to the Company such information as is known to it relating to any person appearing to have an interest in the shares held by it. |
(d) | Where the sanctions under article 6.2(a) apply in relation to any shares, they shall cease to have effect at the end of the period of seven (7) days (or such shorter period as the Board may determine) following the earlier of: |
(1) | receipt by the Company of the information required by the notice mentioned in that article; and |
(2) | receipt by the Company of notice that the shares have been transferred by means of an excepted transfer. |
(e) | The Board may in its absolute discretion suspend or cancel any of the sanctions at any time in relation to any Default Shares. |
(f) | Upon sanctions ceasing to have effect in relation to any shares, any dividend withheld in respect of the shares must be paid to the relevant member and, if the Board has effected a transfer under article 6.2(b), the shares must be transferred back to the previous holder. |
(g) | Any new shares in the Company issued in right of Default Shares shall be subject to the same sanctions as apply to the Default Shares, and the Board may make any right to an allotment of the new shares subject to sanctions corresponding to those which will apply to those shares on issue, provided that: |
(1) | any sanctions applying to, or to a right to, new shares by virtue of this article 6.2 shall cease to have effect when the sanctions applying to the related Default Shares cease to have effect (and shall be suspended or cancelled if and to the extent that the sanctions applying to the related Default Shares are suspended or cancelled); and |
(2) | article 6.2(a) shall apply to the exclusion of this article 6.2(g) if the Company gives a separate notice under article 6.1 in relation to the new shares. |
(h) | Where, on the basis of information obtained from a member in respect of any shares held by such member, the Company gives a notice under article 6.1 to any other person, it shall at the same time send a copy of the notice to the member. The accidental omission to do so, or the non-receipt by the member of the copy, shall, however, not invalidate or otherwise affect the application of article 6.2. |
(i) | For the purposes of articles 6.1 and 6.2: |
(1) | an excepted transfer means, in relation to any shares held by a member: |
(A) | a transfer pursuant to acceptance of a takeover offer (within the meaning of article 116 of the Companies Law) in respect of shares in the Company; |
(B) | a transfer in consequence of a sale made through any stock exchange on which the shares are normally traded; or |
(C) | a transfer which is shown to the satisfaction of the Board to be made in consequence of a sale of the whole of the beneficial interest in the shares to a person who is unconnected with the member and with any other person appearing to be interested in the shares; |
(3) | a person, other than the member holding a share, will be treated as appearing to have an interest in such share if the member has informed the Company that the person has, or might have, an interest in such share, or if the Company (after taking account of any information obtained from the member or, pursuant to a notice under article 6.1, from anyone else) knows or has reasonable cause to believe that the person has, or may have, an interest in such share; |
(4) | a person shall be treated as having an interest in the Company’s shares if, for the purposes of sections 13(d) and 13(g) of the Exchange Act, the person would be deemed to constitute a beneficial owner of the share (which shall include holding a CDI); and |
(5) | reference to a person having failed to give the Company the information required by a notice, includes reference to: |
(A) | the person having failed or refused to give all or any part of it; |
(B) | the person having given any information which the person knows to be false in a material particular or having recklessly given information which is false in a material particular; and |
(C) | the Company knowing or having reasonable cause to believe that any of the information provided is false or materially incorrect. |
(e) | Nothing in article 6.2 limits the powers of the Company under article 6.1 or any other powers of the Company whatsoever. |

(1) | a failure to give notice, or the giving of a defective notice, of the meeting unless the person at the beginning of the meeting objects to the holding of the meeting; and |
(2) | the consideration of a particular matter at the meeting which is not within the business referred to in the notice of the meeting, unless the person objects to considering the matter when it is presented. |

(e) | Unless otherwise provided in the appointment of a proxy, attorney or Representative, an appointment will be taken to confer authority: |
(1) | even though the appointment may refer to specific resolutions and may direct the proxy, attorney or Representative how to vote on those resolutions, to do any of the acts specified in article 7.11(f); and |
(2) | even though the appointment may refer to a specific meeting to be held at a specified time or venue, where the meeting is rescheduled, adjourned or postponed to another time or changed to another venue, to attend and vote at the rescheduled, adjourned or postponed meeting or at the new venue. |

(i) | Where the Company receives an instrument appointing a proxy or attorney in accordance with this article 7.11 and within the time period specified in article 7.11(h)(1), the Company is entitled to: |
(1) | clarify with the appointing member any instruction in relation to that instrument by written or verbal communication and make any amendments to the instrument required to reflect any clarification; and |
(2) | where the Company considers that the instrument has not been duly executed, return the instrument to the appointing member and request that the member duly execute the instrument and return it to the Company within the period determined by the Company under article 7.11(h)(2) and notified to the member. |
(j) | The member is taken to have appointed the Company as its attorney for the purpose of any amendments made to an instrument appointing a proxy in accordance with article 7.11(i)(1).

(h) | A director who has an interest in a matter that is being considered at a meeting of the Board may, despite that interest, be present and be counted in a quorum at the meeting, unless that is prohibited by the Companies Law, but may not vote on the matter if such interest is one which to a material extent conflicts or may conflict with the interests of the Company and of which the director is aware, and in respect of any such matter the decision of the chairperson of the meeting shall be final. No act, transaction, agreement, instrument, resolution or other thing is invalid or voidable only because a director fails to comply with this prohibition. |

(B) | references to “Ineligible Consideration CDIs” also included any of that Eligible Shareholder’s Scheme Consideration that has been issued to the Sale Nominee. |

(ii) | prevents Allkem or New TopCo from providing consideration to any particular Scheme Shareholder in accordance with this clause 4, or the payment or issuance of such consideration is otherwise prohibited by applicable law, Allkem or New TopCo (as applicable) will be entitled to: |

(B) | not issue (or, in the case of Allkem, direct New TopCo not to issue), or issue (or, in the case of Allkem, direct New TopCo to issue) to a permitted trustee or nominee, such Scheme Consideration as that Scheme Shareholder would otherwise be entitled to under clause 4.3, |
(b) | New TopCo and Allkem (as applicable) may deduct and withhold from any consideration that would otherwise be provided to a Scheme Shareholder in accordance with this clause 4, any amount that New TopCo or Allkem (as applicable) determines is required to be deducted and withheld from that consideration under any applicable law, including any order, direction or notice made or given by a court of competent jurisdiction or by another Government Entity. |

4.8 | Consideration Shares to rank equally |

(B) | references to “Ineligible Consideration CDIs” also included any of that Eligible Shareholder’s Scheme Consideration that has been issued to the Sale Nominee. |
(b) | Where the issue of Scheme Consideration to the Sale Nominee under this Scheme would result in a breach of law, Allkem must use its reasonable best efforts to appoint another person as the Sale Nominee in accordance with clause 4.4. |

(B) | not issue (or, in the case of Allkem, direct Arcadium Lithium not to issue), or issue (or, in the case of Allkem, direct Arcadium Lithium to issue) to a permitted trustee or nominee, such Scheme Consideration as that Scheme Shareholder would otherwise be entitled to under clause 4.3, |
(b) | Arcadium Lithium and Allkem (as applicable) may deduct and withhold from any consideration that would otherwise be provided to a Scheme Shareholder in accordance with this clause 4, any amount that Arcadium Lithium or Allkem (as applicable) determines is required to be deducted and withheld from that consideration under any applicable law, including any order, direction or notice made or given by a court of competent jurisdiction or by another Government Entity. |

A sale of the share by the Company is valid even if a Transmission Event occurs to the member before the sale. |

(2) | for the purposes of article 4.1(f)(1), unless the Board decides otherwise, an amount paid on a share in advance of a call is to be taken as not having been paid until it becomes payable; and |
(3) | interest is not payable by the Company on any dividend or any amounts payable therewith. |
(g) | The Board may fix a record date for a dividend. |
(h) | A dividend in respect of a share must be paid, subject to the rules of any Designated Stock Exchange (including any rules relating to the settlement of transfers of securities), to the person who is registered, or entitled under articles 5.1, 5.2 and 5.3 to be registered, as the holder of the share: |
(1) | where the Board has fixed a record date in respect of the dividend, on that date; or |
(2) | where the Board has not fixed a record date in respect of that dividend, on the date fixed for payment of the dividend, |
(i) | When resolving to pay a dividend, the Board may direct payment of the dividend from any available source permitted by law, including: |
(1) | wholly or partly by the distribution of specific assets, including paid-up shares or other securities of the Company or of another body corporate, either generally or to specific members; and |
(2) | to particular members wholly or partly out of any particular fund or reserve or out of profits derived from any particular source, and to the other members wholly or partly out of any other particular fund or reserve or out of profits derived from any other particular source. |
(j) | Where a person is entitled to a share because of a Transmission Event, the Board may, but need not, retain any dividends payable on that share until that person becomes registered as the holder of that share or transfers it. |
(k) | The Board may retain from any dividend payable to a member any amount presently payable by the member to the Company and apply the amount retained to the amount owing. |
(l) | The Board may decide the method of payment of any dividend or other amount in respect of a share.

(1) | by such electronic or other means approved by the Board directly to an account (of a type approved by the Board) nominated in writing by the member or the joint holders; or |
(2) | by cheque sent to the address of the member shown in the register of members or, in the case of joint holders, to the address shown in the register of members of any of the joint holders, or to such other address as the member or any of the joint holders in writing direct. |

(1) | may be made payable to bearer or to the order of the member to whom it is sent or any other person the member directs; and |
(2) | is sent at the member’s risk. |
(n) | If the Board decides that payments will be made by electronic transfer into an account (of a type approved by the Board) nominated by a member, but no such account is nominated by the member or an electronic transfer into a nominated account is rejected or refunded, the Company may credit the amount payable to an account of the Company to be held until the member nominates a valid account. |
(o) | Where a member does not have a registered address or the Company believes that a member is not known at the member’s registered address or cheques have been returned undelivered or other payment methods have failed on more than one occasion, the Company may credit an amount payable in respect of the member’s shares to an account of the Company to be held until the member claims the amount payable or nominates a valid account. |
(p) | An amount credited to an account under articles 4.1(n) or 4.1(o) is to be treated as having been paid to the member at the time it is credited to that account. The Company will not be a trustee of the money and no interest will accrue on the money. The money may be used for the benefit of the Company until claimed or otherwise disposed of according to applicable law. |
(q) | If a cheque for an amount payable under article 4.1(l) is not presented for payment for at least eleven (11) calendar months after issue or an amount is held in an account under articles 4.1(n) or 4.1(o) for at least eleven (11) calendar months, the Board may stop payment on the cheque and invest or otherwise make use of the amount for the benefit of the Company until claimed or otherwise disposed of according to applicable law. |
(r) | A dividend that remains unclaimed for a period of ten (10) years after it became due for payment shall be forfeited to, and shall cease to remain owing by, the Company. |
(s) | Provided the directors act reasonably and in accordance with the Companies Law, they shall not incur any personal liability to the holders of shares conferring a preference for any damage that they may suffer by reason of the payment of an interim dividend on any shares having deferred or non-preferred rights. |
(a) | Subject to: |
(1) | any rights or restrictions attached to any shares or class of shares; and |
(2) | any special resolution of the Company; |
(3) | forming part of the undivided profits of the Company; |
(4) | representing profits arising from an ascertained accretion to capital or a revaluation of the assets of the Company; |
(5) | arising from the realisation of any assets of the Company; or |
(6) | otherwise available for distribution as a dividend. |
(b) | The Board may resolve that all or any part of the capitalised amount is to be applied: |
(1) | in paying up in full, at an issue price decided by the Board, any unissued shares in or other securities of the Company; |
(2) | in paying up any amounts unpaid on shares or other securities held by the members; |
(3) | partly as specified in article 4.2(b)(1) and partly as specified in article 4.2(b)(2); or |
(4) | any other method permitted by law. |
(c) | Articles 4.1(f), 4.1(g), 4.1(h), and 4.1(s) apply, so far as they can and with any necessary changes, to capitalising an amount under this article 4.2 as if references in those articles to: |
(1) | a dividend were references to capitalising an amount; and |
(2) | a record date were references to the date the Board resolves to capitalise the amount under this article 4.2. |
(d) | Where the terms of options (existing at the date the resolution referred to in article 4.2(b) is passed) entitle the holder to an issue of bonus shares under this article 4.2, the Board may in determining the number of unissued shares to be so issued, allow in an appropriate manner for the future issue of bonus shares to options holders. |
(a) | To give effect to any resolution to reduce the capital of the Company, to satisfy a dividend as set out in article 4.1(i)(1) or to capitalise any amount under article 4.2, the Board may settle as it thinks expedient any difficulty that arises in making the distribution or capitalisation and, in particular: |
(1) | make cash payments in cases where members are entitled to fractions of shares or other securities; |
(2) | decide that amounts or fractions of less than a particular value decided by the Board may be disregarded to adjust the rights of all parties; |
(3) | fix the value for distribution of any specific assets; |
(4) | pay cash or issue shares or other securities to any member to adjust the rights of all parties; |
(5) | vest any of those specific assets, cash, shares or other securities in a trustee on trust for the persons entitled to the distribution or capitalised amount; and |
(6) | authorise any person to make, on behalf of all the members entitled to any specific assets, cash, shares or other securities as a result of the distribution or capitalisation, an agreement with the Company or another person which provides, as appropriate, for the distribution or issue to them of shares or other securities credited as fully paid up or for payment by the Company on their behalf of the amounts or any part of the amounts remaining unpaid on their existing shares or other securities by applying their respective proportions of the amount resolved to be distributed or capitalised. |
(b) | Any agreement made under an authority referred to in article 4.3(a)(6) is effective and binds all members concerned. |
(c) | If a distribution, transfer or issue of specific assets, shares or securities to a particular member or members is, in the Board’s discretion, considered impracticable or would give rise to parcels of securities that do not constitute a marketable parcel, the Board may make a cash payment to those members or allocate the assets, shares or securities to a trustee to be sold on behalf of, and for the benefit of, those members, instead of making the distribution, transfer or issue to those members. Any proceeds receivable by members under this article 4.3(c) will be net of expenses incurred by the Company and trustee in selling the relevant assets, shares or securities. |
(d) | If the Company distributes to members (either generally or to specific members) securities in the Company or in another body corporate or trust (whether as a dividend or otherwise and whether or not for value), each of those members appoints the Company as such member’s agent to do anything needed to give effect to that distribution, including agreeing to become a member of that other body corporate. |
(a) | The Board may set aside out of the Company’s profits any reserves or provisions it decides. |
(b) | The Board may appropriate to the Company’s profits any amount previously set aside as a reserve or provision. |
(c) | Setting aside an amount as a reserve or provision does not require the Board to keep the amount separate from the Company’s other assets or prevent the amount being used in the Company’s business or being invested as the Board decides. |
(a) | Subject to the following articles about the transfer of shares, a member may transfer any certificated shares or, Uncertificated shares in accordance with the CREST Order, to another person by completing an instrument of transfer, in a common form or in a form approved by the directors, executed: |
(1) | where the shares are fully paid, by or on behalf of that member; and |
(2) | where the shares are partly paid, by or on behalf of that member and the transferee. |
(b) | Subject to the provisions of the CREST Order the transferor of a share is deemed to remain the holder until the name of the transferee is entered in the register in respect of it. |
(a) | The Company shall register the transfer of any shares held in Uncertificated form by means of a relevant system in accordance with the Companies Law and the CREST Order and the rules of the relevant system. |
(b) | The Board may, in its absolute discretion, refuse to register any transfer of an Uncertificated share where permitted by these articles, the Companies Law and the CREST Order. |
(a) | An instrument of transfer of a certificated share may be in any usual form or in any other form which the Board may approve and shall be signed by or on behalf of the transferor and (except in the case of a fully paid share) by or on behalf of the transferee. |
(b) | The Board may, in its absolute discretion, refuse to register any instrument of transfer of a certificated share: |
(1) | which is not fully paid up but, in the case of a class of shares which has been admitted to trading on the Designated Stock Exchange, not so as to prevent dealings in those shares from taking place on an open and proper basis; |
(2) | on which the Company has a lien; or |
(3) | as otherwise required by applicable law. |
(c) | The Board may also refuse to register any instrument of transfer of a certificated share unless it is: |
(1) | left at the registered office of the Company, or at such other place as the Board may decide, for registration; |
(2) | accompanied by the certificate for the shares to be transferred and such other evidence (if any) as the Board may reasonably require to prove the title of the intending transferor or his right to transfer the shares; and |
(3) | in respect of only one class of shares. |
(a) | The Board may suspend registration of the transfer of shares at such times and for such periods (not exceeding 30 days in any calendar year) as it determines. |
(b) | The registration of transfers of shares or of transfers of any class of shares may be suspended at such times and for such periods (not exceeding 30 days in any year) as the Board may determine in its discretion. Unless otherwise permitted by the CREST Order, the Company may not close any register relating to a participating security without the consent of the approved operator of the relevant system. |
(a) | If the Board so decides, the Company may charge a reasonable fee for the registration of any instrument of transfer or other document relating to the title to a share. |
(a) | The Company shall be entitled to retain any instrument of transfer which is registered; but an instrument of transfer which the Board refuses to register shall be returned to the person lodging it when notice of the refusal is given. |
(a) | Subject to article 5.7(c), where a member dies, the only persons the Company will recognise as having any title to the member’s shares or any benefits accruing on those shares are: |
(1) | where the deceased was a sole holder, the legal personal representative of the deceased; and |
(2) | where the deceased was a joint holder, the survivor or survivors. |
(b) | Article 5.7(a) does not release the estate of a deceased member from any liability on a share, whether that share was held by the deceased solely or jointly with other persons. |
(c) | The Board may register a transfer of shares signed by a member before a Transmission Event even though the Company has notice of the Transmission Event. |
(d) | A person who becomes entitled to a share because of a Transmission Event may, on producing such evidence as the Board requires to prove that person’s entitlement to the share, choose: |
(1) | to be registered as the holder of the share by signing and giving the Company a written notice stating that choice; or |
(2) | to nominate some other person to be registered as the transferee of the share by executing or effecting in some other way a transfer of the share to that other person. |
(e) | The provisions of these articles concerning the right to transfer shares and the registration of transfers of shares apply, so far as they can and with any necessary changes, to a notice or transfer under article 5.7(d) as if the relevant Transmission Event had not occurred and the notice or transfer were executed or effected by the registered holder of the share. |
(f) | Where two (2) or more persons are jointly entitled to a share because of a Transmission Event they will, on being registered as the holders of the share, be taken to hold the share as joint tenants and article 2.13 will apply to them. |
(a) | The Company may give notice to any person whom the Company knows or has reasonable cause to believe: |
(1) | to hold an interest (as defined in article 6.2(i)(4)) in the Company’s shares (of a class of shares admitted to trading); or |
(2) | to have held an interest in the Company’s shares (of a class of shares admitted to trading) at any time during the three (3) years immediately preceding the date on which on which the notice is issued. |
(b) | The notice may require the person: |
(1) | to confirm that such person holds such an interest in the Company’s shares or (as the case may be) to state whether or not it is the case, and |
(2) | if such person holds, or has during that time held, any such interest, to give such further information as may be required in accordance with the following provisions of this article 6.1. |
(c) | The notice may require the person to whom it is addressed to give particulars of the person’s own present or past interest in the Company’s shares held by such person at any time during the three (3) year period mentioned above. |
(d) | The notice may require the person to whom it is addressed, where: |
(1) | such person’s interest is a present interest and another interest in the shares subsists, or |
(2) | another interest in the shares subsisted during the three (3) year period mentioned above at a time when such person’s interest subsisted, to give, to the best of such person’s knowledge, such particulars with respect to that other interest as are required by the notice. |
(e) | The particulars referred to in articles 6.1(c) and 6.1(d) include: |
(1) | the identity of any person who holds an interest in the shares in question; and |
(2) | the terms of any agreement or arrangement to which any person who holds an interest in such shares is or was party: |
(A) | relating to the exercise of any right conferred by the shares or the acquisition of any interest in the shares; or |
(B) | which constitutes a Derivative Security. |
(f) | The notice may require the person to whom it is addressed, where the person’s interest is a past interest, to give (to the best of such person’s knowledge) particulars of the identity of the person who held that interest immediately upon the person ceasing to hold it. |
(g) | The information required by the notice must be given within such reasonable time as may be specified in the notice. |
(a) | If a member, or any other person appearing to have an interest in shares held by that member, has been given a notice under article 6.1 and has failed in relation to any shares (the Default Shares) to give the Company the information thereby required within three (3) Business Days from the time reasonably specified in the notice, the following sanctions shall apply, unless the Board otherwise determines in relation to the Default Shares: |
(1) | the member shall not be entitled in respect of the Default Shares to be present or to vote (either in person or by representative or proxy) at any general meeting or at any separate meeting of the holders of any class of shares or on any poll, or to exercise any other right conferred by membership in respect of the Default Shares in relation to any such meeting or poll; |
(2) | any dividend (or other distribution) payable in respect of the Default Shares shall be withheld by the Company (without interest) and the member shall not be entitled to elect to receive shares instead of any such dividend (or other distribution); and |
(3) | no transfer, other than an excepted transfer, of any shares held by the member may be registered unless: |
(i) | the member is not in default as regards supplying the information required; and |
(ii) | the member proves to the satisfaction of the Board that no person in default as regards supplying such information has an interest in any of the shares the subject of the transfer. |
(b) | In support of article 6.2(a), the Board may, at any time while sanctions under article 6.2(a) apply in relation to any shares, effect a transfer of the shares (or any interest in them) in favour of such nominee as specified by the Board. |
(c) | Where any person appearing to have an interest in the Default Shares has been duly served with a notice or copy thereof and the Default Shares which are the subject of such notice are held by a person holding shares or rights or interests in shares in the Company on a nominee basis who has been determined by the Company to be an approved nominee (an Approved Nominee): |
(1) | the provisions of this article 6 shall be treated as applying only to such Default Shares held by the Approved Nominee and not (insofar as such person’s apparent interest is concerned) to any other shares held by the Approved Nominee; and |
(2) | where the member upon whom a default notice is served is an Approved Nominee acting in its capacity as such, the obligations of the Approved Nominee as a member of the Company are limited to disclosing to the Company such information as is known to it relating to any person appearing to have an interest in the shares held by it. |
(d) | Where the sanctions under article 6.2(a) apply in relation to any shares, they shall cease to have effect at the end of the period of seven (7) days (or such shorter period as the Board may determine) following the earlier of: |
(1) | receipt by the Company of the information required by the notice mentioned in that article; and |
(2) | receipt by the Company of notice that the shares have been transferred by means of an excepted transfer. |
(e) | The Board may in its absolute discretion suspend or cancel any of the sanctions at any time in relation to any Default Shares. |
(f) | Upon sanctions ceasing to have effect in relation to any shares, any dividend withheld in respect of the shares must be paid to the relevant member and, if the Board has effected a transfer under article 6.2(b), the shares must be transferred back to the previous holder. |
(g) | Any new shares in the Company issued in right of Default Shares shall be subject to the same sanctions as apply to the Default Shares, and the Board may make any right to an allotment of the new shares subject to sanctions corresponding to those which will apply to those shares on issue, provided that: |
(1) | any sanctions applying to, or to a right to, new shares by virtue of this article 6.2 shall cease to have effect when the sanctions applying to the related Default Shares cease to have effect (and shall be suspended or cancelled if and to the extent that the sanctions applying to the related Default Shares are suspended or cancelled); and |
(2) | article 6.2(a) shall apply to the exclusion of this article 6.2(g) if the Company gives a separate notice under article 6.1 in relation to the new shares. |
(h) | Where, on the basis of information obtained from a member in respect of any shares held by such member, the Company gives a notice under article 6.1 to any other person, it shall at the same time send a copy of the notice to the member. The accidental omission to do so, or the non-receipt by the member of the copy, shall, however, not invalidate or otherwise affect the application of article 6.2. |
(i) | For the purposes of articles 6.1 and 6.2: |
(1) | an excepted transfer means, in relation to any shares held by a member: |
(A) | a transfer pursuant to acceptance of a takeover offer (within the meaning of article 116 of the Companies Law) in respect of shares in the Company; |
(B) | a transfer in consequence of a sale made through any stock exchange on which the shares are normally traded; or |
(C) | a transfer which is shown to the satisfaction of the Board to be made in consequence of a sale of the whole of the beneficial interest in the shares to a person who is unconnected with the member and with any other person appearing to be interested in the shares; |
(3) | a person, other than the member holding a share, will be treated as appearing to have an interest in such share if the member has informed the Company that the person has, or might have, an interest in such share, or if the Company (after taking account of any information obtained from the member or, pursuant to a notice under article 6.1, from anyone else) knows or has reasonable cause to believe that the person has, or may have, an interest in such share; |
(4) | a person shall be treated as having an interest in the Company’s shares if, for the purposes of sections 13(d) and 13(g) of the Exchange Act, the person would be deemed to constitute a beneficial owner of the share (which shall include holding a CDI); and |
(5) | reference to a person having failed to give the Company the information required by a notice, includes reference to: |
(A) | the person having failed or refused to give all or any part of it; |
(B) | the person having given any information which the person knows to be false in a material particular or having recklessly given information which is false in a material particular; and |
(C) | the Company knowing or having reasonable cause to believe that any of the information provided is false or materially incorrect. |
(e) | Nothing in article 6.2 limits the powers of the Company under article 6.1 or any other powers of the Company whatsoever. |
(a) | A general meeting may only be called: |
(1) | by a Board resolution; or |
(2) | as otherwise required by the Companies Law. |
(b) | The Board may, by public announcement, change the venue for, postpone or cancel a general meeting, but: |
(1) | a meeting that is called in accordance with a members’ requisition under the Companies Law; or |
(2) | any other meeting that is not called by a Board resolution, |
(c) | At an annual general meeting, only such nominations of persons for election to the Board shall be considered and such other business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual general meeting, nominations and other business must be a proper matter for member action and must be: |
(1) | specified in the notice of general meeting given by or at the direction of the Board in accordance with article 7.2; |
(2) | brought before the meeting by or at the direction of the Board or a duly authorised committee thereof; or |
(3) | otherwise properly brought before the meeting by a member who: |
(A) | is a member of record of the Company (and, with respect to any beneficial owner, if different, on whose behalf such business is proposed or such nomination(s) are made, only if such beneficial owner is the beneficial owner of shares of the Company) both at the time the notice provided for in article 7.3 is delivered to the general counsel of the Company and on the record date for the determination of members entitled to vote at the general meeting, |
(B) | is entitled to vote at the meeting, and |
(C) | complies with the procedures and requirements set forth in article 7.3. |
(d) | Except as otherwise provided by the Companies Law, at an extraordinary general meeting, only such business may be conducted as is a proper matter for member action and as shall have been brought before the meeting pursuant to the notice of general meeting given by or at the direction of the Board in accordance with article 7.2. Nothing contained herein shall prohibit the Board from submitting matters to the members at any extraordinary general meeting requested by members. |
(e) | Further, if the Board has determined that directors shall be elected at such extraordinary general meeting, then nominations of persons for election to the Board may be made: |
(1) | by or at the direction of the Board or by the general counsel; or |
(2) | by any member of the Company who satisfies each of the requirements set forth in subclauses (A), (B) and (C) of article 7.1(c)(3) above. |
(a) | Subject to the rules of any Designated Stock Exchange (including any rules relating to the settlement of transfers of securities), notice of a general meeting must be given to each person who at the time of giving the notice: |
(1) | is a member or auditor of the Company; or |
(2) | is entitled to a share because of a Transmission Event and has provided evidence of such entitlement that is satisfactory to the Board. |
(b) | The annual general meeting shall be designated as such and all other general meetings shall be designated extraordinary general meetings. |
(c) | The content of a notice of a general meeting called by the Board is to be decided by the Board, but it must state the general nature of the business to be transacted at the meeting and any other matters required by the Companies Law. |
(d) | Except with the approval of the Board or the chairperson, no person may move any amendment to a proposed resolution or to a document that relates to such a resolution. |
(e) | A person may waive notice of any general meeting by written notice to the Company. |
(f) | Failure to give a member or any other person notice of a general meeting or a proxy form does not invalidate anything done or any resolution passed at the general meeting if: |
(1) | the failure occurred by accident or inadvertent error; |
(2) | before or after the meeting, the person notifies the Company of the person’s agreement to that thing or resolution; or |
(3) | such failure is waived in accordance with article 7.2(g). |
(g) | A person’s attendance at a general meeting waives any objection that person may have to: |
(1) | a failure to give notice, or the giving of a defective notice, of the meeting unless the person at the beginning of the meeting objects to the holding of the meeting; and |
(2) | the consideration of a particular matter at the meeting which is not within the business referred to in the notice of the meeting, unless the person objects to considering the matter when it is presented. |
(a) | For nominations or other business to be properly brought before an annual general meeting by a member in accordance with article 7.1(c)(3), the member must have given timely notice thereof in writing and in proper form to the general counsel of the Company even if such matter is already the subject of any notice to the members or public announcement from the Board. |
(b) | To be timely in the case of an annual general meeting, a member’s notice must be delivered to or mailed and received at the principal executive offices of the Company or such other place designated by the Company for such purposes, not later than the close of business on the ninetieth (90th) day nor earlier than the close of business on the one hundred twentieth (120th) day prior to the first anniversary of the preceding year’s annual general meeting (provided, however, that in the event that there was no annual general meeting in the prior year or the date of the annual general meeting is more than thirty (30) days before or more than ninety (90) days after such anniversary date, notice by the member must be so delivered not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual general meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual general meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Company). |
(c) | In the event the Company calls an extraordinary general meeting for the purpose of electing one or more directors to the Board, any member who is (i) a member of record of the Company (and, with respect to any beneficial owner, if different, on whose behalf such nomination(s) are made, only if such beneficial owner is the beneficial owner of shares of the Company) both at the time the notice provided for in article 7.3 is delivered to the general counsel of the Company and on the record date for the determination of members entitled to vote at the extraordinary general meeting and (ii) entitled to vote in such election of directors may nominate a person or persons (as the case may be) for election to such position(s) as specified in the Company’s notice of general meeting, if the member complies with the procedures and requirements set forth in this article 7.3. To be timely, such notice shall be delivered to the Company’s |
(d) | In no event shall any adjournment, deferral or postponement of a general meeting or the public announcement thereof commence a new time period (or extend any time period) for the giving of a member’s notice as described in these articles. |
(e) | The number of nominees a member may nominate for election at a general meeting shall not exceed the number of directors to be elected at such general meeting, and for the avoidance of doubt, no member shall be entitled to make additional or substitute nominations following the expiration of the applicable time periods. |
(f) | A member’s notice providing for the nomination of persons for election to the Board or other business proposed to be brought before a general meeting shall set out, as to the member giving the notice the following information, in each case as of the date of such member’s notice: |
(1) | the name and address of such member, as they appear on the Company’s books, and of each of its Member Associated Persons; |

(4) | any agreement, arrangement, understanding, or relationship, including any repurchase or similar so-called “stock borrowing” agreement or arrangement, engaged in, directly or indirectly, by such member or any of its Member Associated Persons, the purpose or effect of which is to mitigate loss to, reduce the economic risk (of ownership or otherwise) of any class or series of shares or other securities of the Company by, manage the risk of share price changes for, or increase or decrease the voting power of, such member or Member Associated Person with respect to any class or series of shares or other securities of the Company, or that provides, directly or indirectly, the opportunity to profit from any decrease in the price or value of any class or series or shares or other securities of the Company; |

(a) | Subject to these articles and the Companies Law and to any rights or restrictions attached to any shares or class of shares, at a general meeting, every member present has one vote for each share held as at the Record Time by the member entitling the member to vote, except for partly paid shares, each of which confers only the fraction of one vote which the amount paid (not credited) on the share bears to the total amounts paid and payable (excluding amounts credited) on the share. An amount paid in advance of a call is disregarded for this purpose. |

(2) | by proxy; or |
(3) | by attorney. |
(b) | A proxy, attorney or Representative may, but need not, be a member of the Company. |
(c) | An instrument appointing a proxy is valid if it is in accordance with the Companies Law or in any form approved by the Board. |
(d) | A vote given in accordance with an instrument appointing a proxy or attorney is valid despite the transfer of the share in respect of which the instrument was given if the transfer is not registered by the time at which the instrument appointing the proxy or attorney is required to be received under article 7.11(h). |
(e) | Unless otherwise provided in the appointment of a proxy, attorney or Representative, an appointment will be taken to confer authority: |
(1) | even though the appointment may refer to specific resolutions and may direct the proxy, attorney or Representative how to vote on those resolutions, to do any of the acts specified in article 7.11(f); and |
(2) | even though the appointment may refer to a specific meeting to be held at a specified time or venue, where the meeting is rescheduled, adjourned or postponed to another time or changed to another venue, to attend and vote at the rescheduled, adjourned or postponed meeting or at the new venue. |

(1) | at least forty-eight (48) hours, or such lesser time as specified by the Board in the notice of meeting, (or in the case of an adjournment or postponement of a meeting, any lesser time that the Board or the chairperson of the meeting decides) before the time for holding the meeting or adjourned or postponed meeting or taking the poll, as applicable; or |
(2) | where article 7.11(i)(2) applies, such shorter period before the time for holding the meeting or adjourned or postponed meeting or taking the poll, as applicable, as the Company determines in its discretion. |

(1) | clarify with the appointing member any instruction in relation to that instrument by written or verbal communication and make any amendments to the instrument required to reflect any clarification; and |

(j) | The member is taken to have appointed the Company as its attorney for the purpose of any amendments made to an instrument appointing a proxy in accordance with article 7.11(i)(1). An instrument appointing a proxy or attorney which is received by the Company in accordance with article 7.11(i)(2) is taken to have been validly received by the Company. |
(k) | The appointment of a proxy or attorney is not revoked by the appointor attending and taking part in the general meeting, but if the appointor votes on a resolution, the proxy or attorney is not entitled to vote, and must not vote, as the appointor’s proxy or attorney on the resolution. |

(2) | permit the person to exercise the powers of a proxy, attorney or Representative on the condition that, if required by the Company, such person produce evidence of the appointment within the time set by the chairperson. |
(n) | The chairperson may delegate his or her powers under article 7.11(m) to any person. |
(a) | Subject to the Companies Law, for the purpose of facilitating the giving of voting instructions for any general meeting by any person who holds, or holds interests in, beneficial interests in shares that are held and traded in the DTC System: |
(1) | each DTC Proxy may appoint (whether by way of instrument of proxy, power of attorney, mandate or otherwise) more than one person as its proxy in respect of the same general meeting or resolution provided that the instrument of appointment shall specify the number of shares in respect of which the proxy is appointed and only one proxy may attend the general meeting and vote in respect of any one share; |
(2) | each DTC Proxy may appoint (by power of attorney, mandate or otherwise) an agent (including, without limitation, a proxy solicitation agent or similar person) for the purposes of obtaining voting instructions and submitting them to the Company on behalf of that DTC Proxy, whether in hard copy form or electronic form; |
(3) | each instrument of appointment made by a DTC Proxy or its agent shall, unless the Company is notified to the contrary in writing at least three hours before the start of the meeting (or adjourned meeting), be deemed to confer on the relevant proxy or agent the power and authority to appoint one or more sub proxies or sub agents or otherwise sub delegate any or all of its powers to any person; |
(4) | the Board may accept any instrument of appointment made by a DTC Proxy or its agent as sufficient evidence of the authority of that DTC Proxy or agent or require evidence of the authority under which any such appointment has been made; and |

(A) | make such arrangements, either generally or in any particular case, as it thinks fit (including, without limitation, making or facilitating arrangements for the submission to the Company of voting instructions on behalf of DTC Proxies, whether in hard copy form or electronic form); |
(B) | make such regulations, either generally or in any particular case, as it thinks fit, whether in addition to, or in substitution for, any other provision of these articles; and |
(C) | do such other acts and things as it considers necessary or desirable (including, without limitation, approving the form of any instrument of appointment of proxy or agent, whether in hard copy form or electronic form). |
(b) | If any question arises at or in relation to a general meeting as to whether any person has been validly appointed as a proxy or agent by a DTC Proxy or its agent to vote (or exercise any other right) in respect of any shares: |
(1) | if the question arises at a general meeting, the question will be determined by the chairperson of the meeting in his or her sole discretion; or |
(2) | if the question arises otherwise than at a general meeting, the question will be determined by the Board in its sole discretion. |
(a) | The maximum number of directors is to be determined by the Board, but may not be more than fifteen (15). The Board may not determine a maximum which is less than the number of directors in office at the time the determination takes effect. |
(b) | The Board may appoint any eligible person to be a director, either as an addition to the existing directors or to fill a casual vacancy, but so that the total number of directors does not exceed the maximum number fixed under these articles. |
(c) | The Board or a committee of the Board shall not nominate for election or re-election as director any candidate who has not agreed to tender, promptly following the meeting at which he or she is elected as director, an irrevocable resignation that will be effective upon (i) the failure to receive the required number of votes for re-election at the next annual meeting of members at which he or she faces re-election, and (ii) acceptance of such resignation by the Board. |

For purposes of this article 8.1(d), a majority of the votes cast means that the number of shares voted “for” a director must exceed the number of votes “withheld” with respect to that director. |

(h) | Where the number of persons validly proposed for election or re-election as a director is greater than the number of directors to be elected, the persons receiving the most votes (up to the number of directors to be elected) shall be elected as directors and an absolute majority of votes cast shall not be a pre-requisite to the election of such directors. |

(a) | The Board may make regulations requiring the disclosure of interests that a director, and any person deemed by the Board to be related to or associated with the director, may have in any matter concerning the Company or a related body corporate. Any regulations made under these articles bind all directors. |
(b) | No act, transaction, agreement, instrument, resolution or other thing is invalid or voidable only because a person fails to comply with any regulation made under article 8.6(a). |

(h) | A director who has an interest in a matter that is being considered at a meeting of the Board may, despite that interest, be present and be counted in a quorum at the meeting, unless that is prohibited by the Companies Law, but may not vote on the matter if such interest is one which to a material extent conflicts or may conflict with the interests of the Company and of which the director is aware, and in respect of any such matter the decision of the chairperson of the meeting shall be final. No act, transaction, agreement, instrument, resolution or other thing is invalid or voidable only because a director fails to comply with this prohibition. |
(i) | The Board may exercise the voting rights given by shares in any corporation held or owned by the Company in any way the Board decides. This includes voting for any resolution appointing a director as a director or other officer of that corporation or voting for the payment of remuneration to the directors or other officers of that corporation. |

(e) | A person who attends a meeting of the Board waives any objection that person may have to a failure to give notice of the meeting. |

Item 22. | Undertakings |
(a) | The undersigned registrant hereby undertakes: |
(1) | To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: |
(i) | to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; |
(ii) | to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and |
(iii) | to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. |
(2) | That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. |
(3) | To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. |
(4) | That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use. |
(5) | That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: |
(i) | any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; |
(ii) | any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; |
(iii) | the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and |
(iv) | any other communication that is an offer in the offering made by the undersigned registrant to the purchaser. |
(b) | The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. |
(c) | The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form. |
(d) | The registrant undertakes that every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. |
(e) | Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. |
(f) | The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. |
(g) | The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. |

Olaroz Lithium Facility
SEC Technical Report Summary
1. EXECUTIVE SUMMARY
This report discloses the lithium brine mineral resource for Allkem Limited’s (Allkem’s) Olaroz Lithium Facility (Olaroz). Olaroz is a brine mining and processing facility that began operation in 2015 with the completion of Olaroz Stage 1 (Olaroz 1) producing 17,500 tons per annum (tpa) of lithium carbonate.
Olaroz has embarked on a 25,000 tpa second-stage production expansion initiative (Olaroz 2 or Stage 2) in 2018 which is scheduled to commence production in the second half of 2023 increasing the cumulative site lithium carbonate production capacity to 42,500 tpa.
This individual Technical Report is the initial report to be issued under the S-K §229.1300 regulations (the “SK regulations”) in support of Allkem’s listing on the New York Stock Exchange (NYSE). This report updates Olaroz resources, cost estimates, and economics as of the Effective Date.
The ongoing and proven lithium carbonate production at Olaroz 1, the advanced stage of Olaroz 2 construction and commissioning, and recent market information provide Allkem with sufficiently accurate estimation rigor to develop this report to a suitable level where both capital and operating cost accuracy is ±15% and contingency is less than or equal to 10% as defined by the SK Regulations, with remaining uncertainty associated with an expected 40-year life-of-mine. Olaroz 2 expansion elements such as mine (brine extraction), evaporation ponds, and site service infrastructure are complete, with the processing facility nearing mechanical completion and commissioning activities ongoing. Social, environmental, and government aspects are sufficiently progressed to sustain ongoing operations and progress the production ramp-up of Olaroz 2.
The reported mineral resource is based on data collected up to the Effective Date, including operational data collected from Olaroz 1 and Olaroz 2. The cost and economic estimates are current as of the Effective Date.
Conclusion, recommendations, and forward-looking statements made by QPs are based on reasonable assumptions and results interpretations. Forward-looking statements cannot be relied upon to guarantee Olaroz performance or outcomes and naturally include inherent risk.
1.1 Property Description and Ownership
Olaroz (latitude 23° 27’ 46.54” South, longitude 66° 42’ 8.94” West) is located in the high-altitude Puna region of northwest Argentina, where extensive lithium brine resources are present beneath salars. Olaroz was only the second lithium brine project to be developed in Argentina and the first in 20 years.
The Olaroz Lithium Facility is located in the province of Jujuy at 3,900 m altitude, adjacent to the paved international highway (RN52) that links the Jujuy Provincial capital with ports in the Antofagasta region of Chile that are used to export the lithium carbonate product and to import key chemicals used in the production of lithium carbonate. Olaroz is supplied with natural gas from a nearby existing supply pipeline. The climate in the Olaroz area is severe and can be described as typical of a continental, cold, high-altitude desert, with resultant scarce vegetation. The climate allows year around operation.
Olaroz Lithium Facility
SEC Technical Report Summary
Allkem Limited (Allkem) is the operator and majority owner of the Olaroz Lithium Facility. Allkem Limited holds 66.5% of Olaroz through its local subsidiary Sales de Jujuy S.A. (SDJ), with the remaining project ownership held by Toyota Tsusho (TTC) (25%) and the Jujuy Energía y Minería Sociedad del Estado (JEMSE) (8.5%), hereafter referred to as the “Joint Venture”.
The Joint Venture holds mineral properties that cover the majority of the Salar de Olaroz, including tenements covering 47,615 hectares and two exploration properties (“cateos”) consisting of 33 mining concessions.
Olaroz is fully permitted by the provincial mining authorities and has provincial and federal permits, to allow operations for an initial forty (40) year mine life with renewable options to extend beyond 2053.
This report was amended to include additional clarifying information in October 2023 and November 2023. The basis of the report is unchanged. The changes and their location in the document are summarized in Chapter 2.1
1.2 Geology and Mineralization
The Olaroz salar is located in the elevated Altiplano-Puna plateau of the Central Andes. The Puna plateau of north-western Argentina comprises a series of dominantly NNW to NNE trending reverse fault-bounded ranges up to 5,000-6,000 m high, with intervening internally drained basins at an average elevation of 3,700 m. High evaporation rates together with reduced precipitation have led to the deposition of evaporites in many of the Puna basins since 15 Ma, with borate deposition occurring for the past 8 Myr. Precipitation of salts and evaporites has occurred in the center of basins where evaporation is the only means of water escaping from the hydrological system.
Mineralization in the Olaroz salar consists of lithium dissolved in a hyper-saline brine, which is about eight times more concentrated than seawater. The lithium concentration is the product of the solar evaporation of brackish water which flows into the salar as groundwater and occasional surface water flows. The concentrated brine with lithium is distributed throughout the salar in pore spaces between grains of sediment. The brine also extends a considerable distance away from the salar, beneath alluvial gravel fans around the edges of the salar. These areas are largely unexplored by the company to date. In addition to lithium, there are other elements, such as sodium, magnesium, and boron, which constitute impurities that are removed in the ponds and in the processing plant.
Given the greater depth of exploration from 2019 onward and improved geological understanding the geological interpretation was previously simplified to five major hydrogeological units (UH1 to UH5). The uppermost unit consists of the upper halite and northern sequence of the salar (UH1), underlying sand silt and clay units (UH3), a halite-dominated sequence (UH4), a lower sequence with more sandy units (UH5) and a unit of alluvial sediments that surround the salar (UH2) and extends to considerable depth in the west of the salar.

SEC Technical Report Summary
1.2.1 Porosity Sampling
Porosity samples from 2020 diamond holes were previously sent to the Geosystems Analysis laboratory in Tucson, Arizona, USA for porosity testing using the Rapid Brine Release (RBR) test method to measure specific yield (drainable porosity). Check porosity samples were analyzed in the DB Stephens and Associates laboratory in Albuquerque, New Mexico USA.
One of the diamond holes and the majority of the Stage 2 production wells were profiled with geophysical logging tools, including a Borehole Magnetic Resonance (BMR) tool, that provided in-situ measurements of porosity and permeability. The geophysical logging confirms the correlation of individual sub-units across the salar. An analysis of the BMR data, together with laboratory porosity data from recent and historical cores at Olaroz and core samples collected by Allkem in the Cauchari Project to the south, in the southern extension of the Olaroz basin, provided the basis for assignment of porosity values for the resource estimate. No new laboratory porosity data has been collected since June 2023.
Laboratory-specific yield ([Sy] = drainable porosity) values vary between 9%+/-8% for sandy material, 6%+/-5% for silt mixes, 4%+/-2% for halite, and 2%+/-2% for clay-dominated material, as determined by laboratory samples. The overall specific yield porosity of sediments to 650 m is lower than in the 2011 resource. The resource reduction is due to the presence of the halite-dominated unit (UH4) and lesser sand units below the upper 200 m, except the deeper sand unit.
1.2.2 Brine Sampling
Drilling has confirmed the previously defined lateral zoning in brine concentrations broadly continues at depth, and it is likely that brine will continue to the base of the basin. As drilling has progressed towards the south it has confirmed the previous observations of flow rates in this area, with new wells in the south of the properties. These new wells are producing at:
● | 70 l/s and 629 mg/l (E26), |
● | 54.7 l/s and 539 mg/l (E24 average), |
● | 30.3 l/s and 660 mg/l (E22 average), |
● | 542 mg/l (E09) to 786 mg/l Li (E08), |
● | flow rates from over 10 l/s to over 60 l/s (E09 and E26). |
These wells provide samples representative of the aquifers intersected by these wells. Brine samples are collected weekly for analysis from the original Stage 1 (PP series) and Stage 2 expansion (E series) production wells and from check samples in external laboratories.
Brine samples from historical exploration drilling were analyzed in a number of commercial laboratories, principally the Alex Stuart laboratory in Mendoza, Argentina. Since construction of the Olaroz S1 brine samples have been analyzed in the Olaroz site laboratory, with check samples sent to the Alex Stuart laboratory in Jujuy, Argentina, with analysis of duplicates, standards, and blank samples. Results are considered to be sufficiently robust for resource estimation.

The resource was estimated using the historical sonic and diamond drilling, recent diamond drilling and results from production wells, to maximize use of the available information. SDJ has operated 29 production wells installed to depths of between 300 and 450 m for up to 5 years and 9 productions well installed to 650 m depth for 3 years. These wells provide important production history and continuity of brine concentration over this period to support the updated resource estimation to a 650 m depth.
1.3 Exploration Status
1.3.1 Current exploration
The initial exploration conducted at Olaroz indicated the property contained a very significant brine volume that would support multiple stages of development. The Stage 1 development of 17,500 tpa lithium carbonate was based on drilling conducted to a depth of 200 m, supported by interpretation of the Olaroz basin from gravity and electrical geophysics. The geophysical data indicated the salar occupies a deep basin, which has now been confirmed by drilling to have a depth greater than 1,400 meters locally.
Drilling to support Stage 2 of Olaroz has been to depths between 400 and 650 m, depending on the location within the basin. This deeper drilling has provided further information around sedimentation during basin filling and confirmed that deposition of coarser grained higher porosity and permeability sediments on the western side of the basin. Drilling has been undertaken in a number of stages:
● | Exploration drilling from 2009 through 2011. This included FD, C and CD-series exploration diamond drill holes. |
Olaroz Lithium Facility
SEC Technical Report Summary
● | Production wells for Stage 1, installed to 200 m depth, with some wells subsequently deepened, from approximately 2012 through 2014. These are the PP-series production wells. Later wells included wells below 200 m, such as P301 and P302. |
● | Drilling of deep exploration well E01, during 2019. |
● | Production wells for Stage 2, installed to 650 m depth in the east of Olaroz and 450 m in the west. These are the E-series holes. Three DDH-series diamond holes were drilled along the eastern property boundary in this campaign. |
Geophysics on Olaroz was conducted over multiple campaigns:
● | Audio-magnetotelluric (AMT) and gravity geophysics 2009. |
● | SEV electrical geophysics 2016. |
● | Extensive grid gravity and groundmagnetic survey, 2017, used to define the depth of the basin, which is the lower limit on the resource. |
Drilling has not yet intersected the basement rocks beneath the Salar, despite drilling a 1,400 m deep exploration hole in one of the deeper locations in the basin. The existing model contacts have not been changed at this time. Additional drilling to depth is required to define the lowest extents of basin. This is an underestimation of basement thickness, with recent holes such as E24 and E26 completed to below this surface, while in unconsolidated sediments. This surface will be updated when drilling intersects the basement surface and allows for better control of the contact.
Drilling undertaken to support the Stage 2 resource upgrade has consisted of production well installation and limited HQ diamond exploration holes. Limited accommodation at Olaroz site due to restrictions related to Covid-19 resulted in drilling of only three of the planned 650 m deep HQ diamond holes as monitoring wells. Fifteen new production wells were installed for Stage 2. Production wells have been installed on a 1 km grid, as for the original wellfields.
1.3.2 Exploration Potential
The resource is open both laterally and to depth. Laterally, the resource is currently limited to within the salar outline, except in the south around E26. Very limited drilling has been undertaken outside the salar. This limited drilling, and extensive geophysical surveys, indicate the brine body extends south of Olaroz beneath gravels to Cauchari, where drilling by the now 100% owned South American Salars defined a resource in 2019. Brine is also interpreted to extend north under the Rio Rosario delta. These areas are to be further evaluated to support a third stage of expansion at Olaroz. A combination of diamond and rotary drilling is planned in these areas.
The resource is currently defined to >650 m depth (or more shallowly where the gravity survey indicated the basin may be shallower and drilling is shallower than 650 m) and controlled by the basement contact interpreted from the basin wide geophysical survey.
Olaroz Lithium Facility
SEC Technical Report Summary
One deep exploration hole drilled to 1,408 m, slightly north of the northern production wellfield, has not intersected the basement rock (bedrock). The gravity survey supports a large area of similar depth in this part of the basin. To date no drilling in the Olaroz basin has intersected basement (bedrock).
The Exploration Target ranges between 14 and 33.6 million tonnes (Mt) lithium carbonate equivalent (LCE), depending on the values used for porosity and lithium concentration, having the potential to substantially increase the current resource. It must be stressed that an exploration target is not a Mineral Resource. The potential quantity and grade of the exploration target is conceptual in nature, and there has been insufficient exploration to define a Mineral Resource in the volume where the Exploration Target is outlined. It is uncertain if further exploration drilling will result in the determination of a Mineral Resource in this volume.
1.4 Development and Operations
Olaroz is an established lithium brine production, evaporation, and processing operation. Olaroz has extensive infrastructure and facilities supporting saleable lithium carbonate production.
The Olaroz 1 well field and ponds have been operating successfully since 2013. The Olaroz plant has been processing lithium on site for sale of lithium carbonate product since 2015 as part of the Stage 1 operation.
1.4.1 Mineral Processing and Recovery Methods
The process design was loosely based on that at Silver Peak in the USA. The chemical behavior of the brines under evaporation was studied extensively in pilot scale ponds, along with the key plant process steps such as lime addition, impurity removal and carbonation. The purification process via conversion to lithium bicarbonate was pilot tested at the University of Jujuy. Testing was conducted between 2009 and 2011.
The process design is a conventional pond evaporation and concentration operation. Lithium brine grading approximately 650 mg/L is extracted from the wellfields, pumped to evaporation ponds, and mixed with lime which precipitates magnesium as the hydroxide and gypsum. After concentration brine is processed in the plant to produce lithium carbonate product. These precipitates settle out in the first evaporation pond and primarily halite and Glauber salt are precipitated in the sequence of evaporation ponds as they reach solubility limits. Additional lime is added toward the end of the evaporation sequence to control the Mg levels feeding the plant.
The lithium concentration in the ponds increases progressively to approximately 6,500 to 7,500 mg/l Li, depending on seasonal impacts, prior to processing in the plant. Most of the remaining Mg, Ca and B are precipitated in the plant prior to final conversion of lithium-to-lithium carbonate with soda ash at 85°C. Some of the primary lithium carbonate is redissolved as soluble bicarbonate using carbon dioxide at low temperature, filtered, and purified by ion exchange, then reprecipitated as lithium carbonate that exceeds battery grade purity.
Olaroz Lithium Facility
SEC Technical Report Summary
These products are then filtered, washed, and dried for packaging in bulk bags and trucked to the Antofagasta port in Chile for export.
The second stage of Olaroz (Olaroz 2) is near the final stages of construction, using the original design with modifications and improvements based on operation of the Stage 1 project.
1.4.2 Olaroz Stage 2 expansion
Installation of Olaroz 2 expanded production wellfield was completed in 2022. A total of 15 production wells were installed and designed to produce brine from 450- and 650-meters depth, depending on the location in the salar. The expansion wells fill in the space between existing northern and southern wellfields in the center of the salar.
Stage 2 development is designed with a substantial increase in the evaporation pond area with the addition of 9 km2 of new ponds.
A second 25,000 tpa processing plant is completing construction to increase the cumulative annual production to 42,500 tpa LCE. The Olaroz 2 process plant design is based upon the original Stage 1 plant but with improved equipment selection and processing design optimizations based on gained operating experience.
Operation of the Stage 1 plant since 2015 has allowed optimization of many activities and systems in plant operation, with improved operational procedures and performance. Operation since 2015 has proven that the process is reliable and meets product market quality requirements.
1.5 Mineral Resource Estimates
The current June 30, 2023, Mineral Resource estimation is the most recent estimate, and supersedes previous estimates which include:
● | A March 27, 2023, estimate released in a JORC announcement. |
● | An April 2022 NI 43-101 resource estimate technical report. |
● | The 2011 NI 43-101 feasibility study technical report. |
The April 2022 Resource update was the first resource estimate since the resource estimate contained in the 2011 feasibility study technical report containing engineering details of Olaroz. The April 2022 estimate resulted in a substantial expansion in the resource base at Olaroz from 6.4 Mt LCE in the 2011 resource to a total of 16.1 Mt LCE. The updated resource included 5.1 Mt of Measured Resources and 4.6 Mt of Indicated Resources, with the remaining 6.4 Mt classified as Inferred resource. The Inferred resource is below 650 m depth and outside the area of 1 km spaced production (rotary) drilling areas, additional work is needed to upgrade these areas in the future.
Olaroz Lithium Facility
SEC Technical Report Summary
The lithium grade of the measured resource (0-200 m depth) in the center of the Olaroz Salar is 774 mg/l, with the underlying Indicated resource (200-650 m depth) 747 mg/l. This is the area of current and planned Stage 2 brine production. The Inferred resource underlies and surrounds the M&I Resources, with a grade of 596 mg/l.
Resource estimated since 2011 were defined to the base of the basin, as defined by the gravity geophysics. No holes drilled to date have intersected the basement rocks.
The 2011 resource defined as part of the original project feasibility study defined a lithium carbonate (LCE) resource to a depth of 200 m depth. Production wells were subsequently installed to 200 m depth for stage 1 production.
1.5.1 Resource Update effective 30 June 2023
The March 2023 Resource update resulted in an incremental increase in the resource base at Olaroz, with the addition of the Maria Victoria property. The resource was reclassified in June 2023 (documented in this report), based on the results of pumping from Stage 2 wells, with the conversion of a significant part of the indicated resources to measured status. Currently measured resources consist of 11.5 Mt lithium carbonate equivalent (LCE) [previously 7.3 Mt in March 2023], 3.8 Mt [previously 7.1 Mt] of indicated resources, and 7.2 Mt of inferred resources of LCE [previously 6.0 Mt].
Measured resources are defined to cover the entire salar area to a minimum 200 m depth, as exploration drilling was originally conducted across the salar area to 54 m and 200 m depth. The deeper extension of the measured resource is based on the drill hole depth, with the resource 650 m depth in the east of the salar and 450 m deep in the west, where drill holes are shallower. Measured resources are defined to 350 m depth around holes drilled in the Maria Victoria property, in the north of Olaroz.
Lithium brine beneath the measured resource, to 650 m depth, is classified as Indicated, around the western edge of the salar. From 200 to 350 m below surface in the north of the salar (with lesser drilling density), outside the 2.5 km radius of influence of drilling in the Maria Victoria property, and south of the salar around hole E26 are also classified as Indicated Resources.
Inferred mineral resources are defined between 350 m and 650 m in the north of the salar, where there is less drilling. Inferred resources are also defined between 650 m and the base of the basin. The base of the basin is defined by the gravity geophysical survey, with areas significantly deeper than 650 m defined.
Olaroz Lithium Facility
SEC Technical Report Summary
The lithium grade of the measured resource (0-650 m and less in the west of the salar) in the salar is 659 mg/l Li, with the underlying Indicated resource (200-650 m and 200 to 350 m) averaging 592 mg/l Li. This is the area of current Stage 2 brine production. The inferred resource underlies and surrounds the M&I resources, having a grade of 581 mg/l Li for the resource from 350 to 650 m and 655 mg/l for the resource below 650 m. Extension of the resource to the south has increased the resource size but also added sediments with excellent porosity and permeability characteristics, although this has reduced the lithium grade of the resource slightly.
This report contains an update of the Olaroz resource estimated to the base of the basin, as defined by a gravity geophysical survey. The basement surface is an underestimate of the actual depth of the basement, as it has been exceeded by drill holes in multiple locations, including drill hole E01 deep hole to 1,408 m depth. No holes drilled to date have intersected the basement rocks. The deeper part of the basin and extensions of the brine beneath adjacent areas of gravel allow for potential further expansion of production capacity in a third stage of the Olaroz lithium facility beyond 42,500 tonnes per annum. However, it is anticipated this third stage would utilize brine that has not yet been quantified in the north of the Olaroz salar (salar).
This resource update is the first to include resources that are defined outside the surface of the salar (around E26), and it is expected that additional resources will be defined to the north and south of the salar in the future with additional exploration. Exploration carried out by Allkem and Advantage Lithium demonstrated brine at potential economic concentrations continues over extensive areas south of Olaroz, underneath the Archibarca alluvial fan (area of gravels), towards Allkem’s Cauchari Resource, and north beneath the Rosaria delta and surrounding alluvium.
Sediments beneath the salar comprise aquifers with different porosities and permeabilities. The surface outline of the salar is used to delimit the majority of the area of the resource estimate, which is larger than the 2011 Resource. The current resource includes a southern extension where hole E26 has been drilled off the salar and covers some small properties east of and outside the main body of the properties, for a combined total of 148 km2. The brine-saturated sediments are known to extend beneath alluvial sediments surrounding the salar but to date, insufficient drilling has been carried out in these areas to support resource estimation there. The resource estimate is limited laterally by the property boundaries with minority property owners (Lithium Americas Corp and other owners) in the salar to the east and north of the properties owned by Allkem and SDJ.
1.5.2 Inputs and Estimation Methodology
The distribution of lithium and other elements was estimated for this estimate and previous superseded models from April 2022 and March 27, 2023, from point sampling data from the upper 200 m of the model where samples are typically spaced every 6 m in the 200 m holes and 3m or less in the 54 m holes. Below the upper 200 m, the resource was estimated based on the pumped samples from the production wells, with a single average value per hole representing the average pumped value, assigned to the screen intervals from which the hole was pumped.

SEC Technical Report Summary
1.5.3 | Resource Classification |
The block model was constructed with 500 m wide by 500 m length by 20m depth blocks, with blocks only reported inside of the resource area for the portion of the block within the salar outline. The resource estimate was undertaken using Datamine software with variograms developed for the point samples from the upper 200 m. Estimation was undertaken using ordinary kriging. Ordinary kriging is the most commonly used kriging method.
The resource (Table 1-2 and Table 1-3) was estimated using 4 passes with expanding search parameters for the search strategy. The results of the first two passes are nominally equated to blocks classified as measured and indicated, with the latter two passes equating to blocks classified as Inferred.
● | The measured Resources are defined to 200 m across the salar, based on historical exploration drilling. Below 200 m depth they are within 2.5 km of E-series and PE-series (in Maria Victoria) production wells and earlier drilling, extending to 650 m depth in the east of the resource area, shallowing to 450 m in the west. In the north of the salar the Measured Resource is restricted to 350 m depth, around the PE-series holes. |
● | Indicated resources are within 2.5 km of the E26 production well south off the salar and 5 km of the deeper E-series wells and 2.5 km of the PE-series wells overlapping diameters of influence in the north of the salar. Here Indicated Resources are defined to a depth of 350 m (corresponding to the depth of PE-series wells in the Maria Victoria property). These resources are all defined within a tight polygon outline around the salar limit. |
● | Inferred resources are defined below Indicated resources (below 350 m) in the north of the salar, with minor peripheral blocks of Inferred resources in the south of the resource, external to hole E26. Future drilling is expected to significantly increase the classification of Measured and Indicated resources. |
The Resource is presented below inclusive and exclusive of Reserves. Because no Reserve has yet been defined for the Olaroz project, the inclusive and exclusive Resource table are alike.

1.7 | Economic Analysis |
Certain information and statements contained in this section and in the report are forward-looking in nature. Actual events and results may differ significantly from these forward-looking statements due to various risks, uncertainties, and contingencies, including factors related to business, economics, politics, competition, and society. All forward-looking statements in this Report are necessarily based on opinions and estimates made as of the date such statements are made and are subject to important risk factors and uncertainties, many of which cannot be controlled or predicted.
1.7.1 | Market Studies |
The QPs have relied on external market consultants Wood Mackenzie for lithium market related demand and price predictions. The lithium supply chain is expected to remain restricted in the short term (2-3 years) with gradual growth in supply in response to growing demand. This is expected to provide a positive price environment for the Olaroz Stage 2 Project.
Olaroz Lithium Facility
SEC Technical Report Summary
There is a 3 percent mine mouth (boca de mina) royalty on the value of production to the provincial Jujuy government, considered the value of the brine after the deduction of the costs of extraction, processing and transportation. There is an export fee of 4.5% on the FOB price, as regulated by Decree Nr. 1060/20.
In addition to the royalty JEMSE, the Jujuy provincial mining body holds an 8.5% interest in the Olaroz lithium facility, which is to be paid back from their share of Olaroz profit. There are no other royalties, back-in rights, remaining payments, or encumbrances on the Allkem JV or 100% owned Olaroz Lithium properties.
The Olaroz lithium facility permitting process addressed community and socio-economic issues. The Olaroz expansion will provide new employment opportunities and investment in the region, which is expected to be positive.
1.7.2 | Economic estimate |
Olaroz Stage I production will reach nominal capacity of 17,500 metric tons per year (t/yr) of lithium carbonate once all enhancement projects are completed. Olaroz Stage 2 expansion is expected to support a production rate of 25,000 metric tons per year (t/yr) of lithium carbonate for an estimated operational life of approximately 32 years. This would result in the production of approximately 543,030 dry metric tons (dmt) of saleable lithium carbonate. When considering both Stage 1 and 2, the total saleable product is estimated to be 1,310,670 dmt of lithium carbonate for the Life of Mine (LOM).
● | Product Quality: The saleable product for Stage 2 is expected to be of technical grade. However, it’s important to note that the Stage 1 includes both Technical and battery-grade lithium carbonate. |
● | Pre-Tax Net Present Value (NPV): The pre-tax NPV@10% is estimated to be US$ 7,145 million. |
● | Post-Tax Net Present Value (NPV): After considering applicable taxes, the post-tax NPV@10% is estimated to be US$ 4,644 million. |
● | Life of Mine (LOM) Operating Cost: The estimated operating cost over the life of the mine (LOM) is projected to be US$ 4,149 per metric ton of lithium carbonate produced. |
In conclusion, the financial analysis of Olaroz Stage 1 and 2 demonstrates promising results, with substantial net present values and robust projected revenue and operating cash flow figures.
The key metrics are summarized in Table 1-7. Summary of LOM annual financial projection.

The sensitivity analysis examined the impact of variations in commodity prices, production levels, capital costs, and operating costs on Olaroz’s NPV at a discount rate of 10%.
The commodity price has the most significant impact on Olaroz’s NPV, followed by production levels, OPEX, and CAPEX. Price emerges as the most influential factor with a high correlation. Even under adverse market conditions, such as unfavorable price levels, increased costs, and investment challenges, Olaroz Stage 1 and 2 remains economically viable.
Figure 1-1 Sensitivity Chart
Olaroz Lithium Facility
SEC Technical Report Summary
Based on the assumptions detailed in this report, the economic analysis of Olaroz Stage 1 and 2 demonstrates positive financial outcomes. The sensitivity analysis further strengthens Olaroz’s viability, as it indicates resilience to market fluctuations and cost changes.
1.8 | Conclusions and QP Recommendations |
Olaroz hosts a large lithium resource to support Stages 1 and 2. Additional exploration is likely to define additional resources north and south of the existing resources. Olaroz has an operating history from 2013 and a proven lithium production process. There is potential for the expansion of Olaroz and improvement of efficiencies and synergies with expansion and this is currently under evaluation to meet rising market demand.
The study concludes that the operating Olaroz 1 and Olaroz 2 expansion represents economic feasibility. The Olaroz 1 plant has proven effective process design and saleable product quality to support the economic evaluation.
The collected data and models are deemed reliable and adequate to support the Mineral Resource estimate, cost estimates, and the indicated level of study.
The authors recommend monitoring wells be installed for ongoing evaluation of long-term changes in brine levels and brine concentrations to further support and refine long-term economic feasibility. Further exploration drilling is recommended before any further production expansions.

2.6 | Specific Characteristics of Lithium Brine Projects |
Although extensive exploration and development of new lithium brine projects has been underway for the last decade it is important to note there are essential differences between brine extraction and hard rock (spodumene) lithium, base metal, industrial mineral, or precious metal mining. Brine is fluid hosted in an aquifer and thus can flow and mix with adjacent fluids once pumping of the brine commences. An initial in-situ resource estimate is based on knowledge of the geometry of the aquifer, and the variations in porosity and brine grade within the aquifer.
Olaroz Lithium Facility
SEC Technical Report Summary
Brine deposits are exploited by pumping the brine to the surface and extracting the lithium in a specialist production plant, generally following brine concentration through solar evaporation in large evaporation ponds. To assess the recoverable reserve, further information on the permeability and flow regime in the aquifer and the surrounding area is necessary to be able to predict how the lithium contained in brine will change over the Olaroz life. These considerations are examined more fully in Houston et. al., (2011) and in the Canadian Institute of Mining (CIM) and Joint Ore Reserve Committee (JORC) (Australia) brine reporting guidelines. The reader is referred to these key publications for further explanation of the details of brine deposits.

3. | Property Description |
3.1 | Property Location, Country, Regional and Government Setting |
Olaroz (latitude 23° 27’ 46.54” South, longitude 66° 42’ 8.94” West, Gauss Kruger, POSGAR 2007, Zone 3) is located 230 kilometers northwest of the capital city San Salvador de Jujuy in the province of Jujuy at 3,900 m altitude, adjacent to the paved international highway (RN52) that links the San Salvador de Jujuy with ports in the Antofagasta region of Chile. Refer to Figure 3-1.
The joint venture holds mineral properties that cover the majority of the Salar de Olaroz, covering 47,615 ha, consisting of 33 mining tenements and 2 exploration properties (“cateos”). Allkem commenced exploration at Olaroz in 2008 and has been extracting lithium since 2013 and producing lithium carbonate since 2015 from the Stage 1 operations of Olaroz. Further, in July of 2023, Allkem achieved first production from the Stage 2 operations of Olaroz.
In addition to its stake in SDJ, Allkem also owns 100% of six properties immediately in the north of Olaroz, which contribute an additional 9,575 ha. The properties in the far north of the salar and over gravel sediments of the Rosario River delta and surrounding alluvial material are interpreted to overlie a deeper extension of the salar. In addition to those six properties, Allkem has also acquired the Maria Victoria property in the north of Olaroz, which contribute an additional 1,800 ha.
None of these six wholly owned Allkem properties are in production. Further exploration drilling and test work is planned to confirm the scale of lithium potential of these properties.
The Olaroz lithium facility site is adjacent to the paved highway RN52 which passes through the international border with Chile, 50 km to the northwest (Jama Pass), continuing to the major mining center of Calama, and the port of Mejillones, near Antofagasta in northern Chile.
Approximately 35 km to the north of Olaroz there is a dehumidifying and compression station on a regional gas pipeline, reached by the N-S road along the west side of Olaroz Salar. A dedicated spur pipeline supplies gas to Olaroz.
Approximately 60 km to the south of Olaroz site a railway crosses from northern Argentina to Chile, providing potential access to several ports in northern Chile. There are several local villages within 50 km of Olaroz site and the regional administrative center of Susques (population 2,000) is within half an hour’s drive.

3.1.2 | Argentinian Licensing System |
Two tenement types exist in the Argentine mining regulations, Cateos and Minas. Cateos (Exploration Permits) are licenses that allow the holder to explore the tenement for a period of time that is proportional to its size. An Exploration Permit of 1 unit (500 ha) is granted for a period of 150 days. For each additional unit (500 ha) the period is extended by 50 days. The maximum allowed permit size is 20 units (10,000 ha) and which is granted for a period of 1,100 days. The period begins 30 days after granting the permit. A relinquishment must be made after the first 300 days, and a second one after 700 days. The applicant should pay a canon fee of $1,600 Argentine pesos per unit (500 ha) and submit an exploration work plan and environmental impact assessment.
Minas (Mining/exploitation Permits) are licenses which allow the holder to exploit the property (tenement) subject to regulatory environmental approval. Minas are of unlimited duration, providing the property holder meets its obligations under the Mining Code. The Olaroz properties are predominantly minas. Requirements to maintain license in good standing include:
● | Paying the annual rent (canon) payments. |

3.3.1 | Agreements and Royalties |
Argentina is a federal country, with significant power invested in the provinces, which control mining within the province. There is a 3% mine mouth (boca de mina) royalty on the value of production to the provincial Jujuy government, considered the value of the brine after the deduction of the costs of extraction, processing and transportation.
Olaroz Lithium Facility
SEC Technical Report Summary
In addition to the royalty JEMSE, the Jujuy provincial mining body holds an 8.5% interest in the Olaroz lithium facility, which is to be paid back from their share of Olaroz profit. There are no other royalties, back in rights or remaining payments or encumbrances on the Allkem SDJ JV or 100% owned Olaroz Lithium properties. There is an export fee of 4.5% on the FOB price, as regulated by Decree Nr. 1060/20.
3.4 | Environmental Liabilities and Other Permitting Requirements |
The properties where extraction of lithium is ongoing are subject to ongoing environmental approval, with ongoing monitoring of water levels and quality conducted throughout the properties and the surrounding area. Annual or more frequent reports on the environmental condition of the properties are prepared and regularly filed with the relevant authorities.
Ongoing EIA renewals are required on all properties as outlined in Table 3-2.
The properties outside of the production area been subject to limited or no exploration drilling. Environmental permits are held for these properties, although no significant exploration has yet been conducted.

SEC Technical Report Summary
4. ACCESSIBILITY, CLIMATE, PHYSIOGRAPHY, LOCAL RESOURCES, AND INFRASTRUCTURE |
This section summarizes the accessibility, climate, physiography, local resources, and infrastructure for Olaroz.
4.1 | Accessibility |
The most accessible route to Olaroz area is from the city of San Salvador de Jujuy. The route RN 9 follows northwest approximately 60 km to Purmamarca. From here the RN 52 road ascends steeply to the Puna Plateau and continues from 150 km to the regional town of Susques. From Susques the international road to Chile continues to climb, before descending on the eastern side of the Olaroz Salar. This paved road continues around the southern end of Olaroz, crossing the divide with the Cauchari Salar to the South. The entrance road to the Olaroz processing plant is reached by a gravel road (Route 70) that turns off the international road and continues north along the western side of the salar for 6 km. The entrance to Olaroz is on the right, on the alluvial gravels that slope down to the salar.
An alternative way to reach Olaroz is from Salta, which has an international airport and a range of hotels and services. To drive from Salta, one follows mostly paved Route 51, approximately 170 km northwest from Salta to the town of San Antonio de los Cobres, continuing on the gravel provincial highway Route 51 to the town of Olacapato, before continuing north along the west (Route 70) or east side (new alternative route) of the Cauchari Salar, reaching the international road that leads to Chile. The gravel road (Route 70) to the Olaroz plant entry is a continuation of Route 70 on the western side of the Cauchari Salar. From the road along the east of the Cauchari Salar the turn off to Olaroz along Route 70 is 6.5 km to the west along the paved international road, in the direction of the Chilean border (Figure 4-1).
Both Jujuy and Salta have international airports with regular flights to Buenos Aires. Olaroz has full infrastructure available including water (dedicated wells), gas (pipeline), and electricity (from gas generation). The Puna gas pipeline crosses to the north of Olaroz Salar and Allkem has constructed a connection to this pipeline for Olaroz. A railway line connecting northern Argentina to Chile passes along the southern end of Cauchari Salar, approximately 60 km to the south of Olaroz site.

4.2 | Topography, Elevation, Vegetation and Climate |
4.2.1 | Physiography |
The Altiplano-Puna is an elevated plateau within the central Andes (see Figure 4-1 and Figure 3-1 above). The Puna covers part of the Argentinean provinces of Jujuy, Salta, Catamarca, La Rioja, and Tucuman with an average elevation of 3,700 masl (Morlans, 1995; Kay et. al., 2008).
The Altiplano-Puna Volcanic Complex (APVC) is associated with numerous stratovolcanoes and calderas. Investigations have shown that the APVC is underlain by an extensive magma chamber at 4-8 km depth (de Silva et al., 2006).
The physiography of the region is characterized by generally north-south trending basins and ranges, with canyons cutting through the Western and Eastern Cordilleras. There are numerous volcanic centers in the Puna, particularly in the Western Cordillera, where volcanic cones are present along the border of Chile and Argentina.
Dry salars (Salar) in the Puna occur within many of the closed basins (see Figure 4-2 below), which have internal (endorheic) drainage. Inflow to these salars is from summer rainfall, surface water runoff and groundwater inflows. Discharge is though evaporation.
Physiographic observations regarding Olaroz Salar include:
● | The drainage divides between the Olaroz Salar to the north and the Cauchari Salar to the south is coincident with the international Hwy RN 52 crossing between these Salar and continuing west to link Argentina to Chile at the Jama pass. | |
● | The large Archibarca alluvial fan is present on the southwestern side of Olaroz Salar and in part separates the Olaroz Salar and Cauchari Salar. There are a number of smaller alluvial fans along the western side of the Olaroz Salar, with larger alluvial fans on the margins of the Salar in the north. Alluvial fans are also developed further south in Cauchari Salar. | |
● | The Rio Rosario enters the Olaroz Salar from the north and flows south towards the center of the Salar, only causing flooding in the Salar in wetter years. This is the major freshwater flow into the Olaroz Salar. | |
● | The Rio Ola enters the Cauchari-Olaroz drainage basin from the west and flows through the Archibarca alluvial fan, infiltrating into the gravels of the alluvial fan. | |
● | The Olaroz – Cauchari drainage basin covers some 6,000 km2 with the nucleus of Olaroz Salar covering approximately 160 km2. | |
● | The surface of the Olaroz Salar is essentially flat and comprised of several different types of salt crust, which reflect the different history of the salt crust. |

SEC Technical Report Summary
4.2.2 | Climate |
The climate in the Olaroz area is severe and can be described as typical of a continental, cold, high-altitude desert, with resultant scarce vegetation. Daily temperature variations may exceed 25°C. Solar radiation is intense, especially during the summer months of October through March, leading to high evaporation rates. The rainy season is between the months of December to March. Occasional flooding can occur in the salar during the wet season. Year-round travel and operation are possible with appropriate clothing.
There are three weather stations operating for Olaroz since 2012, with one station located in Cauchari Salar and two stations located further north in Olaroz Salar. The stations maintain a continuous record of temperature, atmospheric pressure, and liquid precipitation, among other meteorological variables of interest. There is no continuous record of direct evaporation measurements, and therefore evaporation is calculated indirectly from other parameters.
In addition to these stations, the National Institute of Agricultural Technology INTA has historical monthly rainfall data in northwestern Argentina, for the period 1934-1990 (Bianchi, 1992), of which three stations (Susques, Sey and Olacapato) are located near the Cauchari-Olaroz hydrological basin. The locations of the relevant weather stations for Olaroz are shown in Figure 4-3 and Table 4-1 provides summary information for each of the stations.
4.2.2.1 | Precipitation |
The rainy season is between the months December and March when most of the annual rainfall occurs often in brief convective storms that originate from Amazonia to the northeast. The period between April and November is typically dry. Annual rainfall tends to increase towards the northeast, especially at lower elevations. Significant control on annual rainfall is exerted by ENSO (El Niño-Southern Oscillation) (Houston, 2006a) with significant yearly differences in rainfall linked to ENSO events. Figure 4-4 shows the average monthly rainfall data at the ponds monitoring site on Olaroz and Figure 4-5 shows annual rainfall for relevant weather stations shown in Figure 4-3. The average annual precipitation is approximately 49.5 mm for Olaroz site from 2015-2020. Figure 4-6 shows the long-term rainfall for weather stations in Figure 4-3 with actual or factored data.

4.2.2.2 | Temperature |
Temperature records are available from the Liming and Piletas stations since 2012. Average monthly temperature data are available from the Olacapato, Susques and Sey stations for the period between 1950 and 1990. Table 4-2 shows the average monthly temperature for the five stations in Olaroz area, with temperatures varying from 1.2 to 11.1 degrees at the Piletas site. Figure 4-7 shows the average monthly temperature distribution throughout the year.

4.2.2.3 | Evaporation |
Various approaches have been carried out to determine the evaporation for Olaroz Salar. Measurements for Olaroz Salar include sampling and monitoring of fresh water and brine Class A evaporation pans since 2008 (Figure 4-8 and Table 4-3).
The pan evaporation data are plotted in Figure 4-8 and show that the maximum evaporation rates occur during October, November, and December. During the summer months of January through March, a decrease in wind speed and increase in cloud cover tend to decrease the effective evaporation. The minimum evaporation takes place during the winter months, when lower temperatures have a direct impact on evaporation. The data also shows that the evaporation of brine is lower than freshwater with differences of 21% in winter months and up to 47% in the summer months.
Figure 4-7 was prepared with PAN A Bis data from the Piletas (ponds) station, which has a composition of 70% freshwater and 30% brine (to prevent freezing in winter), which is the fluid composition most similar to freshwater used in the evaporation pan measurements.
The Piletas and Vaisala stations present absolute values of maximum evaporation in the area, given they are in the center of the basin, where climatic conditions are more favorable for evaporation in the nucleus of the salar. The Olacapato station is at the south of the salar in an alluvial zone. For the water balance the potential evaporation from each sector of the basin has been calculated. The sectors are defined as lower alluvial and marginal domains (with similar sedimentological characteristics), salar nucleus and upper-level alluvial sediments (coarser gravels). This information has been used to develop the water balance for the basin.

4.2.2.4 | Wind |
Strong winds are frequent in the Puna, reaching speeds of up to 80 km/h during warm periods in the dry season. During summer, the wind is generally pronounced after midday, usually calming during the night. During this season, the winds are warm to cool. During winter wind velocities are generally higher and wind is more frequent, with westerlies the predominant wind direction.
4.2.3 | Vegetation |
Due to the extreme weather conditions in the region, the predominant vegetation is of the high-altitude xerophytic type adapted to high levels of solar radiation, winds and severe cold. The vegetation is dominated by woody herbs of low height from 0.40 -1.5 m, grasses, and cushion plants. With high salinity on its surface, the nucleus of the salar is devoid of vegetation.
Olaroz Lithium Facility
SEC Technical Report Summary
In compliance with local regulations, SDJ undertakes ongoing environmental monitoring. The different vegetation areas are summarized below:
● | Bushy steppes | |
● | Mixed steppes | |
● | Salar |
Fauna is adapted to the extreme living conditions of high aridity, intense sunlight, and very low nightly temperatures. Many animals are nocturnal or have acquired certain physiological features and behaviors that allow them to survive in the harsh environment. The most significant mammals in the region are the vicuña (Vicugna Vicugna) and llama (Lama Glama – which are domesticated) cameloid species, foxes (Dusicyon, Lycalopex) are present and prey on small rodents such as the mole (Oculto or Tuco-Tuco – Ctenomys Opimus) and the Puna mouse (Auliscomys Sublimis). Olaroz is located within the Reserva Provincial de Fauna y Flora Olaroz – Cauchari (a regional flora and fauna reserve) and vicuñas are often seen in the vicinity of Olaroz or within Olaroz area.
4.3 | Surface Water Inflows |
The Olaroz Salar is a closed (endorheic) basin, meaning that there are no surface or groundwater outlets. Consequently, all water that enters the salar from the surrounding basins must be lost by evaporation under natural conditions. Numerous surface water catchments drain to the salar (Figure 4-9, showing drainages), the most important being the Rio Rosario through the northern fan-delta and the Rio Ola which enters the basin from the west via the Archibarca alluvial fan (Figure 4-10, showing topography). The Rio Ola flows infiltrates into the gravels of the Archibarca alluvial fan before reaching the Olaroz Salar.
The Rio Rosario and Rio Ola have been monitored over the last decade since exploration commenced on the Olaroz Salar. Measurements of flow are taken regularly and compared with rainfall.
4.3.1 | Rio Rosario |
At the point where the Rio Rosario (Figure 4-9) enters the salar nucleus the catchment area is approximately 2,000 km2. The significant catchment relief which varies from >5,000 m where it rises on the flanks of Volcan Coyaguaima, to 4,000 m at the salar, result in significant precipitation and significant runoff. Flow monitoring has been undertaken since 2008 where the river disgorges from bedrock at 3,995 m and starts to infiltrate the basin sediments.

4.3.2 | Rio Ola |
The Rio Ola (Figure 4-11) enters the Salars de Olaroz and Cauchari through the Archibarca alluvial fan from the west. Its catchment area is approximately 1,200 km2, but relief is much lower than the Rosario catchment, with a maximum elevation of 4,400 m. Flow monitoring where the river leaves the catchment and infiltrates the fan at 4,000 m indicates a variable rate of flow between 4-14 l/s. Peak flows occur during the winter months (Figure 4-12) when evaporation is at a minimum. The results of monitoring shallow piezometers around the margins of the salar, and at the north of the Archibarca alluvial fan are shown below (Figure 4-13).
Note: The channel crosses a bedrock pass and enters the Archibarca alluvial fan, where it infiltrates before entering the salar (after Flosolutions 2019, Advantage Lithium PFS).

4.4 | Local Infrastructure and Resources |
There are several local villages within approximately 50 km of the Olaroz Project site. These include: Olaroz Chico (18 km north), Huancar (35 km east), Pastos Chicos (40 km southeast), El Toro (50 km north), Catua (40 km southwest), Puesto Sey (53 km southwest) and Olacapato 62 km south. The regional administration is located in the town of Susques (population ~2,000) some 45 km northeast of the Olaroz Project site. Susques has a regional hospital, petroleum and gas services, and a number of hotels. A year-round camp exists at Olaroz site and provides all services and accommodations for Olaroz operations. Operating personnel are sourced from the surrounding area and the closest cities of Jujuy and Salta, where many supplies are also sourced.

5. HISTORY
This section summarizes the history of Olaroz.
5.1 | Historical Exploration and Drill Programs |
5.1.1 | Orocobre (now Allkem) pitting and drilling program 2008 |
Allkem (previously Orocobre until 2021) undertook pit sampling of the Olaroz Salar on a variable grid between March and May 2008, to evaluate lithium concentrations and the superficial salar geology. The initial sampling included a total of 62 brine samples from 60 pits. The results of the sampling were positive and justified the development of exploration drill holes to define a resource on Olaroz.
Allkem undertook a drilling program between 4 September and 2 December 2008 using Falcon Drilling. Twenty-two HQ3 diamond core holes were drilled, totaling 1,496.3 m. Drillhole locations were based on handheld GPS readings and their location is shown in Figure 5-1, together with other later drill holes. The initial 16 HQ3 diamond drill holes (core diameter 61 mm) in the program were drilled on a variable grid, to an average depth of 60 m. Two holes in this program were drilled to greater depths of 125.4 and 199 m. Six further HQ3 holes were drilled as monitoring wells for the hydrogeological test work.
Diamond drilling was carried out using triple tubes. However, core recoveries were low, with an average recovery of only 44%. The poor core recovery was attributed to the unconsolidated nature of the salar deposits and loss of the sand and other unconsolidated layers during drilling. Lithological units encountered include sand, silt, clay, halite and ulexite (borate).
Geophysical logs, self-potential, short, and long resistivity, and natural gamma were run in the 7 holes which had been cased to significant depths. The logging was limited to the upper sections of these holes because of fine sediment filling the basal sections through the slotted casing. Geophysical logs, together with geological logs of the recovered material provided the basis of the geological interpretation. Since the geophysical logs did not extend to the full depth of most holes, the interpretation of the deeper lithologies relied solely upon the core logging.
The drill logs were interpreted to show a near-surface halite layer, termed Zone 1. Beneath the halite unit zone 2 consisted of mixed clays, sands, and silts down to around 45-60 m below the salar surface. For holes deeper than 60 m, the underlying units were assigned to Zone 3, which showed a significant change being more consolidated, with higher clay content.
The core drill holes were reamed out with a tricone bit to a diameter of 165 mm (6 ½”) and a well screen of 100 mm (4”) diameter PVC was installed from 0.5 m below surface to the total depth of the hole, with 2-3 cm long slots. Subsequent to completion of the wells, they were developed by airlifting to establish data on potential yields, to ensure that all drilling fluid and cuttings were removed, and the brine bearing zones were in good hydraulic connection with the test well.
Olaroz Lithium Facility
SEC Technical Report Summary
During airlift development and subsequent testing, airlift flow rates were monitored with a V notch weir, or more normally by filling a known volume. The airlift flow data established wells with high yields and several with low yields. This information was used to plan the subsequent pumping tests. Brine sampling was undertaken by Company staff in December 2008, with re-sampling of some wells during February 2009.
At three of the test wells, two additional holes drilled were constructed as observation wells for pumping tests carried out by Company staff. Pump testing consisted of three constant rate drawdown tests of between 5.5- and 24-hours duration, and five pumped well recovery tests. Airlift yields of up to 4.9 l/s were achieved. (Australian Groundwater Consultants & Environmental, 2009) analyzed the results, which indicated permeability ranging from 0.5-5 m/d, and specific yield from 0.02-0.26.
5.2 | Historical Resource and Reserve Estimates |
5.2.1 | Allkem (formerly Orocobre) resource 2009 |
The SDJ properties were acquired by Allkem from 2008 onward. An initial resource estimate was undertaken (Geos Mining, 2009). The estimate was based on only two interpreted horizontal Zones: Zone 1 with an average thickness of 11 m and Zone 2 with an average thickness of 54 m. Values of specific yield were assigned to these zones based on observed field characteristics and literature values. Average values of 0.22 were used for sand lithologies, 0.05 for halite and 0.01 for clays. A lithology-thickness weighted specific yield was calculated for each hole for the estimate. Assays used were based on sampling conducted in 2008 and 2009.
The product of equivalent brine thickness and the average concentration in each hole provided an estimate of tonnage for each drillhole site. These values were then contoured using the minimum curvature method and the total volume calculated. These were then combined with the average lithium concentration of 787 mg/l to define the contained maiden lithium resource.

SEC Technical Report Summary
5.2.2 | Initial Assessment 2009 |
An initial scoping study, equivalent to a Preliminary Economic Assessment study under NI 43-101, was carried out by Allkem in May 2009, following completion of the drilling, testing and the initial resource estimate. This was undertaken when Allkem was only listed on the Australian Securities Exchange and subject to different reporting regulations and terminology.
The study was an internal Allkem exercise, summarizing the work undertaken, the potential process route, the financial assumptions, and costs for capital items. Inputs into the study were provided by staff and consultants with experience on similar salar projects. The objective of the study was to ascertain if Olaroz had economic potential and set the scope for further investigations. The positive outcome of the scoping study led to planning of additional drilling and test work for Olaroz as part of a definitive feasibility study undertaken in 2010/11.
The Preliminary Economic Assessment was preliminary in nature, included Inferred Mineral Resources that by definition are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there was no certainty the preliminary assessment would be realized.
5.2.3 | Feasibility Study 2011 |
Allkem undertook an extensive program of geophysics and drilling from 2009 to 2011 to deliver the Olaroz Project feasibility study. This involved extensive fieldwork, laboratory process testing and updated resource estimation and engineering design. The details of activities are provided in the sections below.
5.2.3.1 | Satellite Image Interpretation |
Satellite images were interpreted to assist with the surface geological mapping in the vicinity of the salar. Satellite imagery was also used to define different geomorphic zones on the salar which have different evaporation rate characteristics (evaporation zonation). Satellite imagery also provided information regarding the surface hydrology and freshwater inflows into the salar. The satellite imagery interpretation was combined with information from the rainfall, evaporation quantified for this region and inflows measured in the Rio Ola and Rio Rosario to develop a water balance for the Olaroz Salar basin, to evaluate the effects of brine extraction over time.
Olaroz Lithium Facility
SEC Technical Report Summary
5.2.3.2 | Surface Geophysics |
Surface geophysics was conducted by Contractor Wellfield Services to evaluate the geometry of the basin and brine body. They undertook measurement of three gravity lines and four AMT lines across the salar and in the area surrounding the salar. The gravity data was modelled to assess the depth of the basin. The gravity model was not used in the 2011 resource estimate, as the depth of the resource was controlled by the depth of drilling, with a maximum of 200 m. The gravity model was subsequently expanded and verified by more detailed gravity measurements made in 2017.
The Olaroz Salar is underlain by a deep basin (gravity data suggests up to 1.2 km deep) bounded by a pair of N-S reverse faults that thrust Cretaceous and Ordovician basement rocks over the basin margins. The basin is infilled with Cenozoic sediments. Pliocene to Recent sediments form a multilayered aquifer that acts as a host to the brine. The brine contains elevated levels of dissolved elements in solution that are of economic interest: lithium, potassium, and boron. Whilst the ultimate origin of lithium and other species is not fully known, they are likely to be associated with the Altiplano-Puna magma body that underlies the whole region.
5.2.3.3 | Drilling |
The 2011 program consisted of extensive drilling across the salar to evaluate the extent of brine mineralization. This program was carried out with the highest quality equipment available and included importing sonic drilling equipment to undertake the shallower part of the drilling program. It was not possible to conduct sonic drilling to 200 m depth, due to limitations with the drilling rig. Therefore, drilling to 200 m was conducted with diamond drilling.
● | Sonic drilling consisted of twenty wells to 54 m depth to investigate the geology and obtain core and brine samples. |
● | Triple tube diamond drilling consisted of six wells to 197 m depth to investigate the geology and obtain core and brine samples. |
● | Core logging was undertaken for geology description and selection of samples for testing for porosity parameters. |
● | Core samples were collected for detailed laboratory porosity analysis of total porosity and specific yield. |
● | Geophysical ole logging was undertaken to support lithological characterization, correlation, and porosity evaluation. |
● | Brine sampling and analysis was undertaken using a bailer methodology, to collect representative brine samples and determine brine chemistry and lithium concentrations. |
● | Pumping tests of up to five months duration were undertaken to investigate flow conditions, determine aquifer properties, and to confirm the ability of wells to produce stable grades. |
● | Off-salar well drilling, water sampling and monitoring was undertaken to assist with development of the water balance and production forecasting for brine extraction. |
Olaroz Lithium Facility
SEC Technical Report Summary
5.2.3.4 | Resource Estimate 2011 |
The 2011 Feasibility Study was the basis for engineering design and ultimately construction of Olaroz Stage 1. Based on the drilling conducted to explore the salar the resource was updated in this report to a total resource of 6.4 Mt of LCE, comprising 1.21 Mt of lithium metal (0.27 Mt as Measured and 0.94 Mt as Indicated), defined to a depth of 200 m.
5.2.3.5 | Project Engineering Design |
Based on the evaporation and engineering test work that was conducted from the start of the Olaroz Stage 1 project to 2011 a chemical process was defined for Olaroz Stage 1, with conventional evaporation ponds and a processing plant. Subsequent to the 2011 Feasibility Study detailed engineering was completed, to build the project. Olaroz Stage 1 was constructed from 2013 through to 2015, with the initial installation of production wells, evaporation ponds and production plant.
5.3 | Agreement with Toyota Tyusho |
Olaroz was built in partnership with Japanese trading Toyota Tsusho Corporation (TTC) and the mining investment company owned by the provincial Government of Jujuy, Jujuy Energia y Mineria Sociedad del Estado (JEMSE).
The partnership with TTC began in January 2010, through the execution of a definitive joint venture agreement to develop Olaroz. This agreement provided a comprehensive financing plan structured to secure TTC’s direct participation in, and support for, funding the planned development at Olaroz. In turn, TTC’s participation in Olaroz was through a 25% equity stake at Olaroz Project level. In a business where product quality is paramount, TTC’s investment provided a strong endorsement of the quality of the Olaroz resource, and the high purity battery grade product produced at the Olaroz Lithium Facility.
5.4 | Agreement with JEMSE |
Jujuy Energía y Minería Sociedad del Estado (JEMSE) became an Olaroz partner in June 2012. JEMSE’s participation in Olaroz is held through an 8.5% equity stake at SDJ level which provides the Provincial Government with a direct interest in the development of the Olaroz Lithium Facility.
The Olaroz Lithium Facility is managed through the operating company, Sales de Jujuy S.A. The shareholders are Sales de Jujuy Pte. Ltd. and JEMSE. The corporate structure is shown in Figure 5-2.

5.5 | Resource Update – April 2022 |
Following the installation of the production wellfields for the Stage 1 project a number of deeper holes were drilled below 200 m depth, with an exploration target reported in October 2014, based on this drilling. Limited additional drilling was conducted until 2019, when the installation of production wells for the Stage 2 production began.
These wells were installed to depths of between 300 and 750 m, with the wells not completed until late 2022. The April 2022 resource update used these holes to provide information on the deeper sediments hosting brine, resulting in a substantial increase in the brine resource, compared to the 2011 resource. This resource was subsequently updated June 30, 2023.
5.6 | Historical Production |
5.6.1 | Production well drilling |
Production holes have been drilled with rotary drilling equipment, as this method is well suited to the installation of the larger diameter pipes and screens that are required for production wells, compared to the narrow diameters of diamond drill holes used for exploration and obtaining porosity and brine samples. There have been two major drilling programs installing production wells. The first of these was from 2012-2014, with the installation of production wells to 200 m depth, and several holes to greater than 300 m. This drilling was followed by the extension of several 200 m holes to 350 m depth and drilling of another hole to 450 m depth, all with rotary drilling equipment. This was followed by the ongoing expansion drilling program, commencing in 2019 and continuing, with the installation of production wells up to 650m deep (Figure 5-3).
Olaroz Lithium Facility
SEC Technical Report Summary
The Olaroz expansion program was designed to include both installation of production wells and drilling of diamond drill holes, which would then be installed as monitoring wells. Due to the complication of logistics related to Covid-19 distancing and limited site accommodation, the planned number of diamond exploration and monitoring wells has not been completed and the installation of production wells was also subject to some delays.
The outcome of this situation is that the geological interpretation and sampling has relied on the installation of the new production wells for deeper information.
Traditionally sampling of brine in salars has relied on collecting samples over discrete intervals (typically with a separation from 3 to 12 m) by packer sampling or using a bailer device to purge fluid from the hole prior to sampling, allowing collection of a representative sample of brine due to inflow of formation brine into the well and sampling device. The complication with this methodology is that significant drilling fluid enters the sediments around the hole and during purging it may not be possible to remove all this fluid prior to collecting a representative brine sample. Fluorescein tracer dye can be used with drilling fluid, so that drilling fluid can be detected by the presence of dye when samples are taken. For the limited diamond drilling completed in the recent diamond drilling Fluorescein has not been used.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 5-3 – Location of Olaroz expansion drill holes and the northern and southern wellfields
Olaroz Lithium Facility
SEC Technical Report Summary
The installation of production wells involves widening the initial pilot hole and flushing the hole before the installation of well casing and screens. A gravel pack is added around the well, to minimize the amount of fine material entering the well. The well is then developed by using a jet of high-pressure air against the filters, allowing the gravel pack to settle in place and removing fine material from the well. A swab device is also used to clean the hole and gravel pack. Following use of these devices a pump is installed in the well and pumped to clean fine material from the hole. Once the pumped brine is confirmed to be free of suspended sediments the well is allowed to equilibrate before undergoing pumping tests to confirm the hydraulic characteristics of the well. For individual wells and drilling contractors’ procedures varied for well development.
Screens are typically installed over long vertical intervals in wells, as outside the high permeability sandy units the sediments constitute a “leaky” package of sediments that liberates brine from the thick sequence of sediments. The brine extracted during pumping comes from different depths in a well is an averaged composition, which is influenced by the permeability of the host sediments, with higher permeability sediments contributing relatively higher flows. Brine extracted from wells has shown minimal variation since the start of pumping on Olaroz in 2012, with the variability on the scale of laboratory uncertainties.
Because of delays with diamond drilling and sampling and the difficulties of collecting brine samples in diamond drill holes to 650 m, assays from the pumped wells to 650 m deep, have been used as part of the resource estimate. Historical diamond drilling to 200 m depth showed the coefficient of variation between lithium in brine samples is low, and consequently use of brine results from production wells is considered reasonable, particularly given the history of pumping and production at the site.
5.6.2 | Historical Production 2013 to 2023 |
Stage 1 of Olaroz was initiated in 2013 and has now been supplemented with the addition of the Stage 2, extracting brine from deeper levels in the salar, where higher capacity sandy aquifer units are noted. Historical brine extraction (as tonnes of lithium carbonate) is summarized in Table 5-1.

6. Geological Setting, Mineralization and Deposit
This section summarizes the deposit and geological setting of Olaroz.
6.1 | Regional Geology |
The Olaroz Salar is located in the elevated Altiplano-Puna plateau of the Central Andes (Allmendinger, Jordan, Kay, & Isacks, 1997). The Puna plateau of north-western Argentina comprises a series of dominantly NNW to NNE trending reverse fault-bounded ranges up to 5,000-6,000 m high, with intervening internally drained basins with an average elevation of 3,700 m. The plateau is approximately 300 km wide at the latitude of Olaroz area and is bounded to the west by the Central Volcanic Zone magmatic arc of the Western Cordillera, and to the east by the reverse faulted Eastern Cordillera (Jordan, et al., 1983). This elevated plateau is a continental hinterland basin that has developed behind the main magmatic arc since the late Oligocene approximately 28 Ma (Carrapa, et al., 2005) (DeCelles & Horton, 2003) (Horton B. , 2012) (Jordan, et al., 1983). The distribution of Precambrian to recent salar sediments is shown in Figure 6-1.
Uplift and exhumation of the hinterland commenced in the late Oligocene when deformation was transferred from the west to the east towards the South American craton, compartmentalizing the former foreland region of the arc into reverse fault-bounded ranges and intervening internally drained basins, and transferring foreland sedimentation further east to what is today the Eastern Cordillera (Bosio, del Papa, Hongn, & Powell, 2010) (Carrapa, et al., 2005) (Coutand, et al., 2001) (Coutand, et al., 2006) (Gorustovich, Monaldi, & Salfity, 2011).
Timing of deformation and exhumation of each basement range in the hinterland appears to have been controlled by local structural or volcanic conditions (Alonso, 1992) (Segerstrom & Turner, 1972) (Vandervoort, 1993). Four main phases of deformation have been recognized: D1 28-25 Ma, D2 20-17 Ma, D3 13-9 Ma, and D4 5-2 Ma (Carrapa, et al., 2005). Rapid uplift and exhumation of the hinterland since the mid Miocene may be related to mantle delamination (Allmendinger, Jordan, Kay, & Isacks, 1997) (DeCelles, et al., 2015) (Kay & Kay, 1993) (Kay, Coira, & Viramonte, 1994) (Wang, Currie, & DeCelles, 2015), with the plateau reaching up to 2500 m by 10 Ma, and 3500 m by 6 Ma (Garzione, et al., 2008).
During the late Oligocene to middle Miocene continental red bed sediments approximately 1-6 km thick were deposited in the isolated, internal drained depocenters separated by mountain ranges within the hinterland, bounded in turn by the major watersheds of the Cordilleras to the west and east (Alonso, 1992) (Boll & Hernández, 1986) (Carrapa, et al., 2005) (Coutand, et al., 2001) (DeCelles, et al., 2015) (Gorustovich, Monaldi, & Salfity, 2011) (Jordan & Alonso, 1987). Sedimentation in the basins consisted of alluvial fans formed from the uplifted ranges with progressively finer fluvial sedimentation and lacustrine sediments deposited towards the low energy centers of the basins.

SEC Technical Report Summary
Deformation in the mid to late Miocene, D3 13-9 Ma (Carrapa, et al., 2005), established significant topography in the Eastern Cordillera (Deeken, et al., 2006), which created the establishment of humid conditions along the eastern Puna margin and a sustained arid to hyper-arid climate within the plateau itself (Alonso, et al., 2006).
During the late Miocene to Pliocene most tectonic deformation was transferred further east to the sub-Andean Santa Barbara thrust and fold belt (Echavarria, Hernández, Allmendinger, & Reynolds, 2003) (Jordan, et al., 1983). However, uplift and exhumation related to mantle delamination continued during this time and another 1-5 km of red bed sediments have accumulated in the hinterland basins in the last 8 Myr (Alonso, 1992) (Boll & Hernández, 1986) (Coutand, et al., 2001) (DeCelles, et al., 2015).
High evaporation together with reduced precipitation has led to the deposition of evaporites in many of the Puna basins since 15 Ma, with borate deposition occurring for the past 8 Myr (Alonso, Jordan, Tabbutt, & Vandervoort, 1991). Precipitation of salts and evaporites has occurred in the center of basins (Figure 6-2) where evaporation is the only means of water escaping from the hydrological system. Evaporite minerals including halite (NaCl), gypsum (CaSO4.2H2O) and ulexite (B5O9CaNa.8H2O) occur disseminated within clastic sequences in the Salar basins and as discrete evaporite beds. In some mature Salars, such as the Hombre Muerto Salar, very thick halite sequences up to 900 m have also formed (Vinante & Alonso, 2006).
Several Miocene-Pliocene volcanic centers, known as the Altiplano-Puna Volcanic Complex (De Silva, 1989), cross the plateau along NW-SE crustal mega fractures (Allmendinger, Ramos, Jordan, Palma, & Isacks, 1983) (Allmendinger, Jordan, Kay, & Isacks, 1997) (Chernicoff, Richards, & Zappettini, 2002) (Riller, Petrinovic, Ramelow, Strecker, & Oncken, 2001). It has been suggested that the Miocene-Pliocene volcanism, particularly tuffs and ignimbrites, are the source of lithium, potassium, and boron, which is released into the Salar basins (Figure 6-1) from hot springs leaching these elements from the volcanic sequences (Godfrey, et al., 2013) (Risacher & Fritz, 2009).
Large changes in moisture availability also occurred on ~100 ka (eccentricity) cycles, synchronous with global glacial cycles. This is most clearly observed in drill cores from Lake Titicaca that record advances of glaciers in the Eastern Cordillera of the Andes and positive water balance in the lake coincident with global glacial stages, whereas glacial retreat and major lake-level decline was coincident with global interglacial periods (Fritz et al., 2007). In contrast, the tropical Andes north of the equator were cold and dry, with low lake levels, during glacial stages and wet and warm in the interglacial stages (Torres et al., 2013). The global glacial stages apparently were also the wettest periods in the western Amazon (Cheng et al., 2013).

In their speleothem record, Cheng et al. (2013) found that the highest d18O values of the last 250 ka occurred during the mid-Holocene, implying that this was the interval of lowest precipitation over that period. In the Lake Titicaca drill core records, based on the abundance of saline diatom taxa and calcium carbonate, earlier interglacial periods were more saline than the Holocene and based on unconformities observed in seismic data (D'Agostino et al., 2002), lake levels were far lower during Marine Isotope Stage 5 than during the mid-Holocene. These low lake levels and highly elevated salinities are a result of negative water balance for a sustained period, requiring a combination of low precipitation and high evaporation, conditions that dropped lake-level below its outlet and caused the gradual build-up of dissolved solids (Cross et al., 2000; Fritz et al, 2007). The greater extremes of salinity and lake levels relative to the mid Holocene could reflect more extreme aridity, but more likely reflects longer-lasting aridity in the former period relative to the latter.
6.2 | Local Geology |
The deposits of the Olaroz – Cauchari basin consist of Cenozoic age sediments with a thickness greater than 1,000 m in some sectors, surrounded by two main fault systems-oriented N-S, that affect the Ordovician and Cretaceous basement.
During much of the Miocene, the basin was slowly filled by coarse-grained alluvial fans and sediments from the erosion of mountain ranges. Alluvial fill interdigitates with sediments that entered the basin from the deltaic fluvial system of the Rosario River to the north or from alluvial fan systems located on the east and west flanks of the Olaroz – Cauchari basin. The Rosario River system is more extensive compared to the alluvial fan systems, covering approximately a 2,000 km2 catchment area to the north. The best developed active alluvial fan system is the Archibarca fan, which originates in the extreme west of the basin and has a catchment area of approximately 1,200 km2.
As the deposition space in the basin narrowed, the sedimentary sequences were reworked, and the sediments became progressively finer higher up in the sequence. During the Pliocene, different sedimentary architectures such as river flats or alluvial fans can be seen, which give rise to predominantly sandy units. With a progressively more arid climate during this period, evaporitic deposits appeared, with abundant halite. This unit is probably of Pleistocene age, and a continuation towards the south, into the Cauchari salar, is observed, which suggests both sub-basins (Olaroz and Cauchari) operate hydrologically as a single entity.
The halite units suggest a continuous subsidence in the center of the basin, linked to variable climatic conditions. Units are developed where mainly clayey sediments dominate, although it is common to observe intercalations of sandy layers and silty sheets and halite layers that would indicate a change in lake facies to fluvial facies, probably linked to the succession of different energy episodes in the Basin. The main source of sedimentation appears to have been the Río Rosario watershed to the north. However, in the middle sector of the basin it is observed that during the formation of the clayey and saline unit sediment began to be supplied into the southwestern part of the salar from the Archibarca sub-basin.
Olaroz Lithium Facility
SEC Technical Report Summary
The upper layer of the sedimentary sequence is predominantly clayey and silty, with intercalations of sand and carbonate layers. In addition, it is common to find levels of halite and ulexite intercalated.
Three major depositional cycles occurred during what is presumed to be largely the Pleistocene-Holocene. The first (deepest) cycle represents clastic sediments deposited in shallow freshwater conditions in much of the salar, influenced by the alluvial and deltaic fans located around the margins of the salar. This cycle is overlaid by a layer that is considered to represent a short but significant transition to more humid conditions. This second (shallower) cycle consists of evaporites (predominantly halite) and suggests salar conditions, with some sediment supply of volcanic or hydrothermal origin.
The third and final cycle of sediments consists of the most superficial deposits in the basin, and suggests a return to relatively arid conditions, coinciding with clastic sediments and a surficial halite layer largely confined to the center of the basin.
The surficial salt crust can be subdivided into three types, depending on its age and development. The oldest crust appears with a rough pinnacle morphology (<0.5 m), as described in other salt flats. A recent crust is represented by halite with well-developed or shrinkage polygons. A further type of crust is reworked by the precipitation of halite and smooth with high reflectance and represents areas that recently suffered flooding due to precipitation or from surface water inflows onto the salar. This texture is most strongly developed along the western side of the salar.
6.3 | Local and Property Geology |
6.3.1 | Structural Setting |
The Olaroz basin is a major north-south trending basin, which together with the Cauchari basin as the southern continuation, has a north south extent of approximately 170 km. The basin is approximately 35 km wide in the Olaroz section. The basin is bounded by Ordovician metasediments and younger sediments, including extensive Tertiary terrestrial sediments, that are present in bands along the eastern and western margins of the basin (Figure 6-2). These units are superimposed by a series of thrusts, trending north south, that have generated the mountain ranges bounding the salars, with the salars subsiding relative to the uplifted mountain ranges. The younger lithologies are generally closest towards the salar. The Olaroz Salar has been confirmed by gravity geophysics and drilling to extend to greater than 1 km deep, with the deepest hole to date drilled to 1,400 m, to confirm the basin stratigraphy. The salar basin has subsided in response to uplift of the surrounding ranges, with normal faulting likely to control the basin subsidence in a consistent orientation through the basin. The structural control of basin development has resulted in consistent patterns of sedimentation in the basin related to uplift and erosion.

SEC Technical Report Summary
6.3.2 | Geomorphology |
The Olaroz properties are located over the large Olaroz Salar, which has dimensions of 20 km north-south and 9 km east west, for an area of approximately 160 km2. The salar is at an altitude of approximate 3,940 m above sea level. The salar is a large salt pan that is surrounded by alluvial fans on the east and west and by a large delta built around the Rosario River in the north. The southern end of the Olaroz Salar is delimited by the international road, which crosses the connection with the Cauchari Salar to the south, which continues down the valley occupied by both salars to the township of Olacapato.
The southern extent of the Olaroz Salar is also delimited by the Archibarca alluvial fan, a large alluvial fan which progrades into the Olaroz Salar and has been an important source of coarser sediments in the salar. The Archibarca fan is built from sediments that are transported by the Rio Ola, which breaches the mountain range which forms the western limit of the Olaroz basin, sourced from a sub-basin further to the west. This sub-basin is the source for freshwater recharge to the Archibarca alluvial fan.
The Olaroz properties are located in the Olaroz basin, although some properties extend over the range to the west. In the north of the Olaroz basin is the Coyaguaima volcano, which is snow covered in winter. Snowmelt and runoff from the northern part of the basin is the major source of inflow to the Olaroz basin.
The Olaroz Salar consists of four different geomorphic zones that were previously identified as having different characteristics related to halite development, seasonal flooding, and evaporation characteristics. These zones are shown in Figure 6-3.
6.3.3 | Geological Units |
The stratigraphy of the Olaroz and Cauchari basins has been controlled by syntectonic sedimentation, due to the N-S orientated faults in the basin and the movements of minor fault systems that tilt the basin in a north direction. This results in a variation in the thickness of the sedimentary units, which can vary from 50 – 200 m south of the Archibarca alluvial fan to 300 – 400 m thick to the north in Olaroz.
Lithological information from the drilling (with holes drilled to 650 m depth for the expansion wellfield) has defined the following sedimentary units, which represent the different facies encountered. Lithological units were previously defined by Houston and Gunn (2011) to 200 m depth, with letters A to G. These have now been summarized into hydro stratigraphic units (numbered UH 1 to 5) based on the more recent drilling to 650 m depth.

SEC Technical Report Summary
A hydro stratigraphic unit does not generally have the same lithology everywhere, as lithology changes laterally across a salar basin. The hydro stratigraphic units are defined on the basis of geological correlation, continuity, porosity, and permeability – with down hole geophysical logging contributing important information to define the units. The location of cross sections showing hydro stratigraphic units is shown in Figure 6-4, which shows the location of the different lithological enviro. The lateral distribution of the different UH units is shown in Figure 6-5. The cross sections in Figure 6-6 to Figure 6-9 show the different unit in different locations across the salar.
Houston’s original (2011) hydrogeological units consisted of the following units, defined to 200 m. superseded by the division into the units shown in Table 6-1:
● | Units A, B, C and D: These units are sequentially surficial halite, clay, a thin sand unit and clayey sediments and represent the deposits localized in the Olaroz Salar, with deeper deposits common between Olaroz and Cauchari. |
● | Unit of sand and gravels in alluvial and deltaic fans: Fd1 through Fd3, F1 and F2 -unconsolidated clastic deposits. |
● | Unit E: Mixed unit of clay and sand. |
● | Unit F: Mixed unit of clay, halite, and sand. |
● | Unit G: Unit with clay containing deep sand intervals. |

6.3.3.1 | Hydro Stratigraphic Unit 1 (UH1) |
This includes Unit A defined by Houston and Gunn (Houston & Gunn, 2011). The modern facies of the Olaroz Salar (late Holocene). On the surface, it is made up of a layer of salt that reaches a thickness of up to approximately 18 m (in historical hole C14). It forms a shallow basin with the main depocenter in the central southern part of the salar. It is dominated by halite with over 80% halite in the northwest and 50% in the southwest, and an increasing sand fraction to the southeast (to 15%), and clay fraction to the northeast (to 98%). Rare, thin beds (<20 cm) of ulexite and gypsum occur towards the northeast associated with the clays (Figure 6-10).

SEC Technical Report Summary
Figure 6-10 – Clay material in Unit UH1, showing bioturbated clayey sediments (Houston & Gunn, 2011)
6.3.3.2 | Hydro Stratigraphic Unit 2 (UH2) |
This unit includes unconsolidated deposits of alluvial, fluvial, and deltaic origin, originating from the alluvial fans located both east and west of the salar and the Rosario Delta developed to the north of the salar. These units correspond to the F1, F2, Fd0, Fd1, Fd2 and Fd3 units defined by Houston and Gunn (Houston & Gunn, 2011). It consists of gravels, breccias, sands and silts, with sandy, clayey and halite groundmass, whose ages are estimated as Pleistocene to the Holocene. This unit includes the active deposits of the Rosario River delta, consisting of carbonates, sands, silts, and clays. It has a variable thickness, with recognized thickness exceeding 150 m in the Archibarca sector and no significant drilling below 50 m depth in the Rosario Delta. These deposits are found interdigitating with shallow evaporite deposits of Unit 1. Distinction between this unit and UH5 is difficult, as it appears UH5 was sourced from the western side of the basin.
6.3.3.3 | Hydro Stratigraphic Unit 3 (UH3) |
Unit UH3 comprises most of the units defined previously by Houston, combined into this much thicker package. Unit B reaches maximum thicknesses of 36.2 m (in sonic drill hole C05). It is a unit of interbedded sediments dominated by clay (>75%) over the whole salar, with a sand fraction reaching 30% in the northeast, and halite reaching 18% in the central east. The clays are plastic, red-brown, green, or black and organic rich. They are frequently laminated, silty, with thin sand lenses. The sand in the northeast is generally fine grained and silty. Halite is fine grained and mixed with silt and clay.
Olaroz Lithium Facility
SEC Technical Report Summary
Unit C is a well-defined sand bed, occurring in all wells throughout the salar and interdigitating with the Rosario fan delta in the north and Archibarca delta in the southwest. Unit C ranges in thickness from 6.6 m (historical well C17) to 0.1 m (in historical well C07), tending to be thicker in the north and south and thinner in the center of the salar. The sand fraction averages 80% and reaches 100%.
Unit D occurs in all wells except those in the northeast. It is likely that Unit D will be replaced by Fd2 in the northeast and F2 in the southwest, associated with the Rosario fan delta and Archibarca fan respectively. The thickness of Unit D increases from 20 m in the central east to over 32 m in the west and northwest. Unit D comprises interbedded sediments dominated by clay and silty clay (>60%), with lesser fractions of sand and thin beds of carbonate (calcrete or travertine). There are rare lenses of halite and ulexite (less than 0.5 m thick) towards the south.
In the extreme north of the salar, Unit D represents the influence of the overflows generated by the deltaic fan of the Rosario River in times of flooding of this river and its superposition towards the nucleus of the Olaroz Salar.
Unit UH3 corresponds to facies associated with a stage of variable climatic conditions, consisting of predominantly clayey sediments with intercalations of very fine sand layers and bands of halite, with a thickness much greater than one hundred meters. These lithofacies suggest they formed during fluvial marsh to lake conditions. Unit UH3 corresponds to the Units B, C D, E and F defined by Houston and Gunn (Houston & Gunn, 2011) and is the predominant unit in which the original Olaroz Northern Wellfield is established in.
The clays are red, brown, or green, sometimes black with entrained organic matter. They are frequently interbedded with silts, sands and even gravel. Carbonates as discrete beds up to 10 m thick (historical hole CD02) are composed of crystalline calcite with an overgrowth of calcite cement. Druses cavities are occasionally present with microcrystalline calcite interiors. They contain some clastic material such as lithics and thin silts beds.
The lithofacies of Unit E suggest mixed fluvio-palustrine and lacustrine conditions, the former prevailing to the north and west, the latter towards the south and east.
6.3.3.4 | Hydro Stratigraphic Unit 4 (UH4) |
Deeper drilling to 650 m has defined the thickness and extent of the halite dominated unit more effectively, with drilling showing Unit G of Houston and Gunn (Houston & Gunn, 2011) is thickest in the east of the salar, with the thickness increasing south towards Cauchari. The unit consists of halite intercalated with clays, which are distinguished in the geophysical logging based on resistivity and other characteristics.
Olaroz Lithium Facility
SEC Technical Report Summary
This unit corresponds to facies associated with a stage of hyperarid climate. The structure and disposition of this unit during its formation, suggests an active subsidence of the basin, with the unit continuing into the Cauchari Salar. This unit is dominated by layers of banded halites and massive halite. The halite crystals that make up the lenses may be corroded or dissolved, resulting in highly porous horizons.
6.3.3.5 | Hydro Stratigraphic Unit 5 (UH5) |
This corresponds to a unit composed of layers of clay and silt, alternating with massive and laminated fine-grained sand. The grain size of the sand appears to be coarser at greater depth. The mineralogy of the sands indicates a source of volcanic origin. The thickness of this unit is variable, with lesser thickness in the east of the basin and the greatest thickness in the southwest of the basin, where an early version of the Archibarca alluvial fan appears to have been active, shedding coarser grained sediment into the basin and developing important high porosity and permeability units. The base of this unit has not yet been recognized. The 1400 m deep stratigraphic hole drilled in the east of Olaroz encountered coarse gravels at depth, which prevented continuation of the hole. In the south of Olaroz it is difficult to distinguish units UH2 and UH5 in drill cuttings.
This unit is likely to be the lateral equivalent to the deep sand unit encountered in drilling at Cauchari, where sandy material has been sourced from the western side of the basin, as appears to be the case at Olaroz.
6.3.3.6 | Basement |
The basement rocks have not been intersected in drilling at Olaroz. There may be more extensive units of sand and gravel at the base of the basin than have been intersected in drilling to date. The basement rocks in the central part of the salar are likely to be Cretaceous to Ordovician in age, with younger tertiary sediments around the edges of the salar, although further drilling would be required to confirm the nature of the basement rocks beneath the salar.
6.4 | Mineralization |
As previously discussed, brine projects differ from hard rock base, precious and industrial mineral projects due to the fluid nature of the mineralization. Therefore, the term ‘mineralization’ should be considered to include the physical and chemical properties dissolved within the fluid (brine), as well as the flow regime controlling fluid flow.
Olaroz Lithium Facility
SEC Technical Report Summary
The brines from Olaroz are solutions nearly saturated in sodium chloride with an average concentration of total dissolved solids (TDS) of 290 g/L and average fluid density of 1.20 g/cm3. In addition to extremely high concentrations of sodium and chloride typical in these salar settings the Olaroz brine also contains significant concentrations of Li, K, Mg, Ca, Cl, SO4 and B.
The Olaroz Salar is large, and the brine is rather homogeneous, although there are some trends in the concentrations of lithium and other elements through the salar sediments. Brine concentrations are lower close to the margins of the salar and in areas where there is significant recharge by freshwater runoff. The Mg/Li ratio averages 2.3, with the SO4/Li ratio averaging 23.
Table 6-2 shows a breakdown of the principal chemical constituents in the Olaroz brine including maximum, average, and minimum values, based on brine samples used in the brine resource estimate that were collected from the production wells.

Figures in Section 11 show the kriged distribution of lithium concentrations in the salar. Concentrations of lithium and potassium show a high degree of correlation. As amp-up of KCl fertilizer is not planned as a by-product, only lithium has been included in the estimation. The kriged three-dimensional distribution of lithium concentrations was used in the updated resource model as further described in Section 11.
Brine quality is evaluated through the relationship of the elements of commercial interest lithium and potassium and the consideration of other elements that must be removed to provide a high-quality lithium product. Other components of the brine constitute impurities, including Mg, Ca, B and SO4. The calculated ratios for the averaged brine chemical composition are presented in Table 6-3.

The precipitation of salts during evaporation of the brine can be represented on a phase diagram known as the Janecke projection, which considers an aqueous quinary system (Na+, K+, Mg++, SO4=, Cl–) at 25°C and saturated in sodium chloride. This can be used when adjusted for the presence of lithium in the brines, with the Janecke projection MgLi2-SO4-K2 in mol % is used to make this adjustment. The Olaroz brine composition is represented in the Janecke Projection diagram in Figure 6-11 along with the brine compositions from other salars. The Olaroz brine composition is compared with those of Silver Peak, Atacama Salar, Hombre Muerto Salar, Rincon Salar and Uyuni Salar in Table 6-4 below.

6.5 | Deposit Types |
Lithium is found in a number of different geological deposit types. The most common are pegmatite bodies, associated with granitic intrusive rocks, and continental brines in salars.
Pegmatite bodies are found in a diverse range of countries, including Australia, Canada, Congo, Russia, USA, and Zimbabwe, with the largest deposits often located in Archean or Proterozoic rocks. Pegmatites are mined by conventional hard rock mining and the spodumene ore is subsequently processed, generally producing lithium hydroxide. In addition to pegmatites lithium is also found in other settings.
Continental lithium brines in salars settings are found principally in Argentina, Chile, Bolivia, and China, with lithium carbonate or lithium chloride produced from these projects. Lithium is rarely found in continental oilfields, where the accompanying produced water is enriched in lithium, probably deriving lithium from evaporite sequences in the stratigraphy.
Olaroz Lithium Facility
SEC Technical Report Summary
Lithium is also found in geothermal systems, rarely at concentrations that may be economic, one example being the Salton Sea geothermal field. A related type of mineralization is lithium present in tuffs or clays in volcanic sequences, where the lithium has likely resulted from geothermal or hydrothermal activity, with examples in the Western USA and Mexico.
Lithium production from salar brines has a number of advantages over hard rock mining of pegmatites and sediments. The principal advantage is the lower operating costs for lithium salar operations, based on the economics of the operating lithium salar producers in Chile and Argentina ( (Lagos, 2009); (Yaksic & Tilton, 2009), Wood Mackenzie. (May 2022 report on lithium market dynamics).
6.5.1 | Salar Types |
Lithium brine projects can also be subdivided into two broad ‘deposit types’ with different characteristics (shown in Figure 6-12), which consist of:
● | Mature Salars (those containing extensive thicknesses – up to hundreds of meters – of halite (salt), such as the Atacama Salar (Chile), and the Livent Hombre Muerto operation (northern Catamarca, Argentina). |
● | Immature Salars, which are dominated by clastic sediments, with limited thicknesses of halite, such as the Olaroz Salar in Jujuy Argentina and the Silver Peak deposit in Nevada, USA, where brine is extracted from porous volcanic ash units. |
Historical development of salar lithium brine projects in Chile and Argentina focused on the development of large mature salars, as these required only shallow drilling and provided excellent brine flow rates from shallow wells. Projects developed at this time (Lithium production from the Atacama Salar, in northern Chile, and from the Hombre Muerto Salar in Argentina dates from 1984 and 1997 respectively) had the most favorable brine chemistry of the mature salars. More recent developments of Salar projects are predominantly immature salars, which are more common, and which can host extractable brine resources to depths of hundreds of meters.
The characteristics of these two different Salar types influence the distribution of the contained brine and brine extraction. It should be noted there may be immature and mature areas within the same Salar basin (such as in the Hombre Muerto Salar in Argentina, where Livent, Posco and Galaxy (now part of the Allkem group) have projects.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 6-12 – Model showing the difference between mature and immature salars (Houston, Butcher, Ehren, Evans, & Godfrey, 2011).
6.5.2 | Mature Salars |
Brine in mature salars is hosted in pore spaces, caverns, and fractures within salt (halite) which has been deposited by the evaporation of brines to produce salt through natural evaporation. Mature salt dominated salars (i.e. Atacama Salar) are characterized by having porosities in the 8 to 12% range within the salt units (Houston, Butcher, Ehren, Evans, & Godfrey, 2011), with the porosity and permeability decreasing with depth, such that by a depth of approximately 50 m the specific yield in matures salars has decreased to several percent (Houston, Butcher, Ehren, Evans, & Godfrey, 2011).
Olaroz Lithium Facility
SEC Technical Report Summary
In these salars the brine resources are principally contained between surface and 50 m below surface, as below this depth there is reduced permeability in the salt, due to salt recrystallization and cementation of fractures.
6.5.3 | Immature Salars |
Immature salars conversely have brine hosted in pore spaces controlled by the porosity and permeability associated with individual layers within the salar sequence. A degree of compaction occurs with increasing depth below surface, but unlike in mature samples significant porosity and permeability characteristics may continue to depths of hundreds of meters in these salars (such as the producing Olaroz Salar and the adjacent Cauchari Salar in Northern Argentina and at the Silver Peak lithium brine mine in Nevada).
The porosity and permeability characteristics may be variable between units, and units with low productivity for brine extraction can alternate with more productive units, due to differences between sediments such as sand and gravel and finer grained silts and clays. The presence of different stratigraphic units in clastic salars typically results in differences in the distribution of the contained brine and influences the recovery of brine as reserves from the defined brine resource, with lower resource to reserve conversion ratios than are typical in hard rock mining situations. It is very important to consider the characteristics of the host aquifers in each salar, together with the aquifer geometry and physical properties, particularly specific yield, and specific storage hydrogeological characteristics.
The characteristics of lithium production from the Silver Peak deposit in Nevada are of importance to Salar bine developers, as many salar deposits currently under evaluation are immature salars which face the same challenges as Silver Peak, which has been operating since 1966 (Lagos, 2009).
The typical architecture of Puna Salar basins (Houston, Butcher, Ehren, Evans, & Godfrey, 2011) consists of:
● | Coarser grained sediments on the margins of a salar basin, with successive inner shells of finer grained clastic units. |
● | Where evaporation is highest an inner nucleus of halite occurs in the approximate center of the salar (depending on the salar topography) and is surrounded by deposits of mixed sulphate and carbonate deposits, together with fine grained clastic sediments. |
Olaroz Lithium Facility
SEC Technical Report Summary
6.5.4 | Buried Salars |
Salars contain sequences of sedimentary deposits with clastic sediments (clay, silt, sand, gravel) and evaporites (principally salt). These sediments progressively accumulate and the surface of the salar consists of salt or fine sediments such as clays. In some cases, due to changes in climate or tectonic events salars are buried by alluvial fan sediments prograding from the margins of basins. In extreme cases salars may be entirely covered by alluvial fan sediments, such that there is no Salar surface in the middle of a closed drainage basin. However, brine can remain in place in the sequence of Salar or clastic sediments beneath the alluvial fans which will often contain fresh to brackish water.
Olaroz contains buried targets beneath the Archibarca alluvial fan in the southwest of the basin and in the north of the basin, where AMT electrical geophysics suggests the presence of brine beneath the Rosario Delta. These areas off the surface of the salar have not yet been explored at Olaroz but are likely to contain significant volumes of brine in addition to that defined directly below the surface of the salar.

7. Exploration
This section summarizes exploration conducted in support of Olaroz.
From 2008 to 2011 Orocobre undertook exploration at Olaroz that culminated in the definition of a resource to a depth of 200 m across the Salar and the completion of a feasibility study for the construction of a new lithium carbonate project, the first in approximately 20 years, following the early salar developments in South America.
An extensive array of work was undertaken to support Olaroz development and that is outlined below. Subsequent exploration was undertaken in 2014 and from 2019 onward to explore and develop the deeper levels of the Olaroz basin.

SEC Technical Report Summary
7.1 | Historical Exploration |
Historical exploration activities are summarized in Section 5.1, and the following sub-sections detail specific surveying, geophysical, drilling, and sampling activities that have been conducted to support Olaroz.
7.2 | Pit Sampling |
Shallow pit sampling was carried out across the Olaroz Salar between March and May 2008 and confirmed the elevated concentration of lithium in brine. This consisted of 62 brine samples collected from 60 pits. These initial sampling results were the basis for Allkem acquiring the properties that form Olaroz.
7.3 | Logging Historical RC Cuttings |
7.3.1 | Exploration drilling |
Three exploration drilling campaigns were previously carried out at Olaroz.
● | Initial drilling consisted of shallow (60 m) diamond drilling in 2008. |
● | This was followed by the drilling conducted at Olaroz in 2010/11 of 19 holes with a sonic rig drilling holes to 54 m and six diamond holes drilled to 200 m, as this is generally beyond the capacity of sonic drilling. |
● | A third drilling program in 2014 involved the drilling of two rotary holes that were installed as test production wells to a maximum depth of 323 m. |
Sonic drilling conducted in 2011 has the advantage that it is “dry” and does not require drilling lubrication. Other methods of drilling require the use of fluid (in salars brine) for lubrication and to carry drill cuttings to the surface. However, the use of drilling fluid causes difficulties sampling brine and can result in contamination of formation brine during sampling. During the 2011 sonic and diamond drilling brine and specific yield samples were collected every 2 to 3 m and a maximum of every 6 m. For the diamond drill holes to 200 m depth brine and porosity samples were collected approximately every 3 to 6 m, depending on hole conditions. This information was used to develop the 2011 resource estimate to 200 m depth.
Olaroz Lithium Facility
SEC Technical Report Summary
7.3.2 | Diamond Drilling and Sampling |
A limited amount of diamond drilling was completed for this resource update, due to logistical challenges associated with Covid-19 (principally a limitation of on-site accommodation). Three diamond holes were completed along the eastern boundary of the Olaroz properties to a depth of 650 m. The holes were drilled as HQ diameter diamond holes, with HWT size casing accompanying the drilling of the diamond holes, to maintain hole stability and facilitate brine sampling.
Cores were recovered in 1.5 m long lexan polycarbonate tubes, which were pumped from the core barrel with water, to recover the core tube. The lexan tube was capped immediately following recovery of the core and stored in core boxes. Samples of core for the laboratory were cut from the base of core runs using a battery powered angle grinder. The laboratory sub-sample was 30 cm long, retained in the polycarbonate tube, and sealed with plastic caps, which were sealed in place with tape, to minimize seepage of brine from the cores. Cores were labelled with the hole name and depth range and sent by courier to the porosity laboratory.
The location of the recent diamond holes drilled in this program is presented in blue on Figure 7-1, along with the location of production wells. Historical diamond holes are shown on Figure 7-2, with production wells.
Brine samples were collected using a packer system during the drilling of the three diamond holes. The packer device was lowered into place in the sediments and inflated using nitrogen gas to expand the packers against the walls of the hole. The space between the packers and the sampling line to the surface was then purged of brine, with three volumes of the packer and sampling line purged, with increased purging required as sampling progressed to greater depths. Sample parameters were monitored during the purging, to establish when parameters such as total dissolved solids and density stabilized. Samples were taken after different purge times and compared to evaluate how values stabilized.
Once this stage was reached, triplicate samples were collected for laboratory analysis and storage. However, despite these procedures it was not possible to reliably purge the packer space sufficiently to allow inflow of uncontaminated brine from the hole walls. Because diamond drilling uses significant volumes of drilling fluid this fluid infiltrates the walls of the hole and when samples are taken returns to the hole. The fluid used for drilling was surficial brine taken from a trench in the north of the salar, noted to consistently have significantly lower lithium concentrations than historical sampling in the vicinity of the three diamond holes. Consequently, brine samples from these three diamond holes were not used in the resource estimate.

SEC Technical Report Summary
Core recovery for the three recent diamond drill holes DDH-02, DDH-04 and DDH-17 was between 86.1 % and 88.6 %. This is higher than historical diamond drilling, which covered a larger spatial area and is summarized in the historical exploration section. Lithium concentration is independent of the core recovery, as it is hosted in brine in sediment pores. Porosity from cores is checked against downhole BMR specific yield measurements.
7.3.3 | Shallow Drilling, Resource Estimate, and Initial Assessment 2008 |
Allkem undertook a drilling program between September 4 and December 2, 2008. Twenty-two HQ3 diamond core holes were drilled, totaling 1,496 m. Drillhole locations were based on handheld GPS readings. The initial 16 HQ3 diamond drill holes (core diameter 61 mm) in the program were drilled on a variable grid, to an average depth of 60 m. Two holes in this program were drilled to greater depths of 125 and 199 m. Six further HQ3 holes were drilled as monitoring wells for the hydrogeological test work. Geophysical logs, self-potential, short, and long resistivity, and natural gamma were run in the 7 holes which had been cased to significant depths.
These, together with geological logs of the recovered material provide the basis of the geological interpretation and subsequent maiden resource estimate in 2009. The drill logs were interpreted to show a near-surface halite layer. Beneath the halite unit a zone of mixed clays, sands and silts was defined down to around 45-60 m below the salar surface. For those holes greater than 60 m deep, the underlying units showed a significant change being more consolidated, with higher clay content. Pumping tests were carried out on three of the test holes, with two additional monitoring wells. The pumping was carried out by airlifting.
The maiden inferred resource for Olaroz was estimated in 2009 using the results of diamond drilling and porosity values assigned to sediments based on field observations and literature values (values of specific yield as 0.22 for sand, 0.05 for halite and 0.01 for clay). The Inferred Resource was estimated as 1.5 Mt of lithium carbonate equivalent. Based on the results of this work a Preliminary Economic Assessment (PEA) was prepared for Olaroz.
7.4 | Surface Geophysical Exploration |
7.4.1 | Audio Magneto Telluric Survey AMT Survey 2009 |
AMT measures temporary variations in the electromagnetic field caused by electrical storms (high frequencies >1 Hz), and the interaction between the solar wind and the terrestrial magnetic field (low frequencies <1 Hz), which allows variations in the electrical subsurface to depths of 2 km or more. The electrical properties of the subsurface depend on Archie’s Law. Hence, it is possible to infer the subsurface variations in fluid resistivity and porosity, although it is important to note that once again the problem of a non-unique solution always exists.
Olaroz Lithium Facility
SEC Technical Report Summary
Data at a total of 136 AMT stations, spaced at 250 m intervals was acquired using Phoenix Geophysics equipment within a range of 10,000-1 Hz, using up to 7 GPS synchronized receptors. The equipment includes a V8 receptor with 3 electrical channels and 3 magnetic channels that also serves as a radio controller of auxiliary RXU-3E acquisition units. Three magnetic coils of different size and hence frequency is used at each station, and non-polarizable electrodes that improve signal to noise ratios. The natural geomagnetic signal during the acquisition period remained low (the Planetary “A” Index was <= 6 for 90% of the acquisition time) requiring 15-18 hours of recording at each station.
● | All stations were surveyed using differential GPS to allow for subsequent topographic corrections. AMT requires a Remote Station, far from the surveyed area, in a low-level noise location to act as a baseline for the acquired data. In Olaroz the remote station had two different locations depending on the sub sector where work was being undertaken. In Olaroz the remote station had two different locations during the Olaroz construction depending on the sub sector where work was being undertaken. |
● | Processing of the AMT data requires the following stages: |
○ | Filtering and impedance inversion of each station. |
○ | 1D inversion for each station. |
○ | Development of a resistivity pseudo section. |
○ | 2D profile inversion (including topographic 3D net) |
An example of the 2D model results is presented below in Figure 7-3. Assuming that the major controlling factor is the fluid resistivity (or conductivity) it is possible to establish a provisional calibration in terms of the brine to freshwater interface. The calibration is based on a series of surface samples of the electrical conductivity (the reciprocal of resistivity) of the fluid in the northern part of the salar across the Rio Rosario delta. As can be seen, the calibration for the 2D inversion is particularly significant, suggesting the main control on bulk AMT resistivity is fluid resistivity.

7.4.2 | Gravity Survey |
Gravity techniques measure the local value of the acceleration, which after correction, can be used to detect variations of the gravitational field on the earth’s surface that may then be attributed to the density distribution in the subsurface. Since different rock types have different densities, it is possible to infer the likely subsurface structure and lithology, although various combinations of thickness and density can result in the same measured density; a problem known as non-uniqueness. Geophysical surveys conducted by Allkem are shown in Figure 7-4.
Olaroz Lithium Facility
SEC Technical Report Summary
Data was acquired at a total of 130 gravity stations spaced at 200 m, coupled with high precision GPS survey data. A Scintrex CG-5 gravimeter (the most up-to-date equipment available) was used, and measurements taken over an average 15-minute period in order to minimize seismic noise. A base station was established with readings taken at the beginning and end of each day’s activities in order to establish and subsequently eliminate from the data the effects of instrument drift and barometric pressure changes. The daily base stations were referred to the absolute gravity point PF-90N, close to Salta where a relative gravity of 2,149.136 mGal was obtained.
Since this point is distant from the Olaroz Salar, intermediate stations were used to transfer the absolute gravity to Pastos Chicos (on the east of the Olaroz Salar) where a relative gravity base station was established with a value of 1,425.313 mGal.

Figure 7-4 – Location of the gravity, AMT and SEV geophysical profiles measured at Olaroz and in Cauchari (after Napa, 2021).
To measure the position and elevation of the stations, a GPS in differential mode was used with post-processing (Trimble 5700). This methodology allows centimeter accuracies, with observation times comparable to or less than the gravity observation. Using a mobile GPS (Rover) the gravity station position data is recorded. Simultaneously, another GPS (Fixed) records variation at a base station located within a radius of 10 to 20 km, to correct the Rover GPS. Both data sets are post-processed to obtain a vertical accuracy of 1 cm.

SEC Technical Report Summary
The raw data was subjected to a tidal correction and corrections for drift, instrument height, ellipsoid, free air, latitude, bouguer and topography.
The Bouguer anomaly can be modelled to represent subsurface geology (Figure 7-5). However, any model is non-unique, and it is essential to consider the known geology and rock density. A four-layer model was developed for the salar based on these original profiles.
Figure 7-5 – Original Olaroz gravity model. Drilling has shown the unconsolidated salar sediments continue to 1.4 km deep, so the green unit is a continuation of these.
7.4.3 | Detailed Gravity and Magnetic Survey 2017 |
A systematic grid gravity and ground magnetic survey was carried out by personnel from the University of San Juan in 2016-17, to better map the contact of the salar sediments with the underlying bedrock and to better establish the depth to bedrock. This evaluation confirmed that bedrock underlying the Salar is over 1 km deep, and deeper on the eastern side of the salar. The survey provided important additional information on the basin geometry. However, no drill holes have intersected the basement rocks underlying the salar and consequently it was not possible to optimize the model with this information.
Olaroz Lithium Facility
SEC Technical Report Summary
Measurement campaigns were carried out in the period from November 14, 2016, to December 21, 2016, acquiring 6205 gravimetric stations georeferenced with post-process DGPS methodology. In addition, 850 km of linear magnetism were processed in the Olaroz Salar (Figure 7-6 & Figure 7-7).
In the acquisition of the regional gravimetric data three geodetic gravimeters were used. These were subjected to drift controls and calibrated before starting the measurements and during the campaign. Detailed measurements were made with two automatic gravimeters with a precision of 0.010 mGal.
For the magnetic determinations, 4 Overhauser magnetometers with 0.02 nT resolution were used, three of them in rover mode and a base magnetometer to record the diurnal variation of the external magnetic field. The magnetic survey provided useful information on probable faults in the bedrock underlying the salar.
Topographic support was performed by differential GPS positioning (post-process), using 4 GPS receivers (2 Trimble 5700 with Recon controller and 2 Topcon Hiper SR receivers with FC500 controller), one of which operated as GPS base station in the Sales de Jujuy plant.
Equipment for the gravity survey consisted of:
● | 1 Automatic Gravimeter, Autograv Scintrex, model CG 5, precision 0.005 mGal. |
● | 1 Automatic Gravimeter, Autograv Scintrex, model CG 3, precision 0.010 mGal. |
● | Thermostated Gravimeter, LaCoste & Romberg, model G, precision 0.030mGal. |
Equipment for the magnetic survey consisted of:
● | GEM GSM system, model 19GW V7, Overhauser total field magnetometer. Equipped with console and sensors (Gradiometer), which measure in walking mode (in motion continuous recording) with GPS positioning. Sensitivity 0.02 nT. |
● | GEM GSM system, model 19 V7, Overhauser total field magnetometer. Equipped with console. One of them registered continuously in base mode. The sensitivity of this equipment is 0.02 nT. |

7.4.4 | Vertical Electrical Soundings 2016 |
A campaign of vertical electrical sounding (VES) geophysics was undertaken in 2016 across the Archibarca alluvial fan and around the salar by a geophysical contractor (Figure 7-8), to define the interface between surficial fresh water and underlying brine. This survey defined the interface successfully and allowed confirmation of the estimated volume of freshwater resources in the Archibarca fan area. Definition of the fresh water-brine interface provided important additional information for the groundwater model development, for a better understanding of the salar margins and long-term monitoring.

Figure 7-8 – VES geophysical equipment in use in the Archibarca area.
The geoelectric method (Figure 7-9) was used with equipment consisting of simultaneous reading of intensity and potential difference. Two stainless steel current electrodes were used with lengths of 1.20 m, due to the characteristics of the area. In addition, two copper potential electrodes in a saturated solution of copper sulfate were used to improve the ground connection.
Copper current cables of 1,000 m in length were used with two sources of 270 volts each used as the power source, for a total of 540 volts. The geoelectric prospecting was carried out with the VES (Vertical Electrical Sounding) method, which used a Schlumberger tetrapolar electrode arrangement. The lengths between the centers of the soundings and current electrodes were variable, up to maximum distances of 1,000 m. The separations between the potential electrodes varied between 1 and 200 m.
The field curve of each VES was plotted on log-log paper where the abscissa corresponds to the OA values and the ordinate to the apparent resistivity values.
The field curves were interpreted by means of specific computer programs RESIST 92 and IPIWIN 2000. The program carried out as many iterations as were necessary in order to fit the computational curve to the field curve. The final result of the geoelectric prospecting was the interpretation of the VESs that, as a whole, determined the geological – hydrogeological environment in depth of each area under investigation. An example curve through the Archibarca area is shown in Figure 7-10.

7.5 | Hydrogeology |
Salars form in arid environments, with the deposition of chemical sediments, with deposition controlled by the concentration of elements in brine and saturation of brine with respect to different minerals which precipitate progressively. Salars typically have an inner nucleus of halite, that is surrounded by marginal zones on the sides of the salar where sulphates and carbonates are deposited.
Fine grained clastic sediments such as clays and muds are typically deposited in salars, some of which may contain organic material from decomposed vegetation. Coarser grained sediments generally occur on the margins of basins and may prograde into the basins from the sides during wetter periods when coarse sediments were transported further.
Drilling at Olaroz has defined the five major hydrogeological units that are discussed in section seven. The general geological environments at Olaroz that relate to the hydrogeological units are as follows:
Olaroz Lithium Facility
SEC Technical Report Summary
7.5.1 | Alluvial fans |
These are best developed on the western margin of the Olaroz Salar, with the largest being the Archibarca alluvial fan, a composite fan developed from the southeast of the Olaroz basin. This consists of coarse gravel, generally with a sandy matrix, with interbeds of more clayey material between thicker and more massive gravel units. The Archibarca fan progrades into the Olaroz and Cauchari Salars and forms the boundary between the two salars. The alluvial fan receives significant recharge from seasonal rain and snowmelt and hosts a resource of fresh water that is used for Olaroz lithium facility water supply. The freshwater overlies brackish water and brine below the gravels.
Drilling shows that historically the Archibarca alluvial fan deposited sediment into the basin from west to east. Coarser sediment from this source was deposited in unit UH5, which can be correlated across the salar, and which supports the highest pumping rates to date in wells such as P302 and E17. In many salars a lower unit with more sand and gravel clastic material is observed, which is likely to reflect different climatic conditions in the Puna region at that time and coarser sedimentation deposited in the earlier stage of basin development.
7.5.2 | Clay and silt |
Clay and silt units form much of units UH3 and UH4, with interbedded sand units. These units cover the central part of the salar and are interbedded with coarser sediments from alluvial fans along the western margin of the salar. These units act as thick leaky aquifers, which release brine continuously, but at lower rates than units with thicker sequences of sand and gravel.
7.5.3 | Halite |
Halite is typically deposited in Salar basins and in Olaroz is developed most consistently in unit UH4, where it forms a thick sequence that is interbedded with clay and silt. The halite (salt) unit is distinct in geophysical logs, as the unit is generally compact and less permeable. However, interbedded coarser grained clastic layers can have higher permeabilities and better production, such as in the southern wellfield.
7.5.4 | Drainable Porosity (Specific Yield) |
Porosity is highly dependent on the host lithology, with different types of porosity related to the size of pores and how brine (fluid) can be extracted from the pores.
Olaroz Lithium Facility
SEC Technical Report Summary
It is important to understand the terminology relating to porosity (Figure 7-11). Total porosity (Pt) relates to the volume of pores contained within a unit volume of aquifer material. Except in well-sorted sands some of the pores are isolated from each other and only the pores that are in mutual contact may be drained. This interconnected porosity is known as the effective porosity (Pe). Assuming the Pe is totally saturated, only part may be drained under gravity during the pumping process. This part of the porosity is known as the specific yield (Sy or the drainable porosity). A portion of the fluid in the pores is retained as a result of adsorption and capillary forces and is known as specific retention (Sr).
Total porosity (Pt) is much higher in finer grained sediments, whereas the reverse is true for Sy, due to the high Sr in these sediments. Lithology is highly variable, with sand-silt-clay mixes spanning the full spectrum of possible porosities. It is only possible to discriminate between the dominant lithology, for example, sand dominant or clay dominant. Consequently, the porosity of sand dominant, or clay dominant lithologies have a wide range with considerable overlap (Table 7-1).
Specific yield analysis was carried out on undisturbed core samples from the partially completed diamond drilling program at Olaroz. Primary samples were analyzed by the Geosystems Analysis laboratory in Tucson, USA. Check samples were analyzed at the DB Stephens laboratory, in Albuquerque, USA. Extensive historical porosity data is also available from porosity sample testing at Olaroz in 2010-11 and from test work conducted at the Cauchari project between 2011 and 2018 in equivalent sediments.

7.5.5 | Porosity Sampling 2020 |
Porosity samples from 2020 diamond holes were previously sent to the Geosystems Analysis laboratory in Tucson, Arizona, USA for porosity testing using the Rapid Brine Release (RBR) test method to measure specific yield (drainable porosity). Check porosity samples were analyzed in the DB Stephens and Associates laboratory in Albuquerque, New Mexico USA.
One of the diamond holes and the majority of the Stage 2 production wells were profiled with geophysical logging tools, including a Borehole Magnetic Resonance (BMR) tool, that provided in-situ measurements of porosity and permeability. The geophysical logging confirms the correlation of individual sub-units across the salar. An analysis of the BMR data, together with laboratory porosity data from recent and historical cores at Olaroz and core samples collected by Allkem in the Cauchari Project to the south, in the southern extension of the Olaroz basin, provided the basis for assignment of porosity values for the resource estimate. No new laboratory porosity data was collected since the April resource.
Laboratory specific yield ([Sy] = drainable porosity) values vary between 9%+/-8% for sandy material, 6%+/-5% for silt mixes, 4%+/-2% for halite and 2%+/-2% for clay dominated material, as determined by laboratory samples. The overall specific yield porosity of sediments to 650 m is lower than in the 2011 resource, due to the presence of the halite dominated unit (UH4) and lesser sand units below the upper 200 m, with the exception of the deeper sand unit.
7.5.6 | Permeability Testing |
Permeability (hydraulic conductivity) is also highly dependent on lithology. Generally finer grained sediments such as clays have lower permeability than coarser grained sediments such as sands and gravels. Near surface halite is often highly permeable, due to a network of fractures, although halite becomes progressively more compact and less permeable with depth. However, cavities and fracture networks are observed in some deeper halite units. The sequence of sediments in the Olaroz Salar exceeds 650 m thickness. Extraction from below 50 m is from semi-confined to confined aquifers.
Permeability for extraction purposes is best measured by conducting pumping tests and evaluating changes in the water level in the pumped well and observation wells. Pumping tests were carried out on wells installed for the expansion program, with variable rates and constant rate pumping tests conducted over periods of up to 48 hours. The results of the pumping tests are summarized below in Figure 7-12 and Table 7-2.
From the available information the heterogeneity of the mixed clay and sand unit in Olaroz is clear. The highest hydraulic conductivity (K) values are generally related to unconsolidated deposits, in particular the Archibarca alluvial fan. Pumping test results show values of between 3.4 and 67 m/d in this material.
The unconsolidated deposits have a range of storage coefficient in the order of 4x10-4 to 2x10-1 related to unconfined to semiconfined parts of the aquifers. The deeper semi-confined to confined units composed of clays, silts and sands have values in the order of 1x10-3 to 3x10-6. Permeability values defined for the hydro stratigraphic units are shown in Table 7-2.

SEC Technical Report Summary
The pumping undertaken at Olaroz for brine production constitutes a long-term pumping test that has been monitored throughout the salar and provides extensive information for understanding the response of the aquifers in response to pumping.

7.6 | Sonic Drilling 2010-2011 |
Boart Longyear was contracted by Allkem to perform the Sonic Drilling program (Figure 7-13) at the Olaroz Salar for the purpose of obtaining continuous geological and brine sampling. The program (C series) involved the drilling and sampling of 20 holes to a depth of 54 m each using a 4” (100 mm) core by 6” (150 mm) casing Sonic sampling system, for a total of 1,080 m drilled. The objective of the sampling was multipurpose: to obtain a near undisturbed sonic core and to obtain uncontaminated brine samples.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 7-13 – Sonic drilling rig operating at Olaroz in 2010.
Sonic technology utilizes high-frequency vibration generated by a highly specialized sonic oscillator, which creates vibration known as “resonance”. The resonance is transferred to the drill pipe, which reduces friction and allows the drill bit at the pipe end to penetrate the formation with minimal disturbance. The rig used was a track mounted 300C ATV Sonic Rig with associated support equipment. Drilling involved:
● | Setting up sonic rig at each location. |
● | Sampling the formation sonically using a 4” (100 mm) core barrel with a polycarbonate (lexan) core barrel liner of 1.5-meter length. The retrieved core barrels were capped and sealed with PVC tape at each end on retrieval at the surface (Figure 7-14). |
● | At the end of each 1.5 m run 6” (150mm) casing was advanced over the core barrel. No drilling fluids were used for the drilling operation. |
● | A 2” diameter x 12” long (in an 18” long split spoon - SS) was then pushed ahead of the casing. The SS had a plastic liner in the barrel and was capped and sealed at the surface (Figure 7-14). |
● | A “push ahead” brine sampling tool was be advanced on the drill string to allow for sampling of the brine, from the space left by the withdrawal of the SS sample. |
● | Once in place, brine was bailed out from within the drill rods using a “bailer” or low flow pump until a representative brine sample was obtained. The sample was identified as in-situ, uncontaminated formation fluid as soon as the fluid being extracted came free of Fluorescein biodegradable dye. |

7.7 | Diamond Drilling 2010-2011 |
Major Drilling was contracted to drill the deep CD series wells. The objectives were the same as for the C series wells; to obtain undisturbed samples of formation and fluid. The drill was with a Major-50 diamond drill rig with triple tube coring capacity. Drilling was usually accomplished using only the fluid encountered in the well during drilling. However, some drill fluid additive was used. This drill fluid was based on brine taken from a pit dug immediately adjacent to the well at the surface. Since this may introduce sampling issues for the in-situ formation fluid, extra care was taken with the addition of fluorescein biodegradable dye to all drill fluid used. In addition, core samples taken were spun in a centrifuge at the BGS research laboratories in order to extract the pore fluid, which was subsequently analyzed and checked against the in-situ samples.
A total of six wells were drilled using this method to an average 200 m depth, for a total of 1,204 m drilled. Core recovery was generally poor, due to the poorly consolidated nature of the sediments (as seen in Table 7-3).

In all sonic and diamond drilled wells, Wellfield Services Ltd. were contracted to run wire-line logs from surface to full depth. The logs were run inside temporary steel casing, but this does not present a problem for gamma and other logs that are able to penetrate the casing with their sensors.
The following logs were run caliper, natural gamma, density, and neutron logs. Electronic data is captured on a continuous centimetric basis down the well. Since the logs had to be run inside steel casing because the holes were unstable if not supported, no electrical logs could be run.
The logs are particularly useful to extrapolate lithology and porosity data into the few zones where there was no core recovery. Caliper logs are run to ensure that the drill hole width is constant within the casing so that the other logs may be corrected for drill hole diameter. The caliper log was sufficiently accurate that it was able to identify casing joints throughout the wells.
Natural gamma logs indicate the received gamma ray intensity at the downhole tool. Since gamma rays are emitted by uranium, thorium and potassium minerals in rocks, the log typically responds to clay minerals and volcanic horizons. Evaporitic minerals such as halite and gypsum have a very low radioactive mineral content and can usually be identified by their low count rate. Thus, gamma is a useful tool for identifying certain types of lithology and for correlating beds across multiple wells.
Density logs emit and receive gamma rays and are thus sometimes known as gamma-gamma tools. This technique measures the bulk density of the rock matrix and pores. Since minerals have characteristic densities, the tool is used for lithological identification when coupled with natural gamma logs. Since it also measures the porosity of the formation it can be used quantitatively to determine total porosity. Since the bulk density depends both on the mineralogy and porosity, any porosity determinations must account for the rock mineralogy. In rapidly changing sequences such as the Olaroz Salar, it becomes extremely difficult to correct the log for these changes. Thus, its principal use is in the assessment of lithology.
Neutron logs measure the hydrogen ion content of the formation and pores adjacent to the sondes. Two downhole tools are used with different spacings so that penetration is both “near” and “far”, with respect to the well diameter. Since the hydrogen ion content is largely determined by the fluid (water) content of the pores, the log can be calibrated to determine the in-situ total porosity.

7.8 | Test Pumping 2011 |
Three test production wells were drilled using a conventional rotary rig to depths of 50 m (P and O series). In some cases, it was possible to drill using only formation fluid, but in several cases, drill fluid had to be used to advance the well. The test production wells were not used for sampling for the resource estimation. The wells were drilled at 12” diameter and completed with an 8” slotted PVC screen with gravel pack to full depth. Immediately after completion the wells were developed by airlift surging for periods up to 10 days to ensure that all drill fluid and fines were removed from the well.
At test production well site P1, three observation wells were drilled at nominal radial distances of 7 m and 18 m from the pumped wells toward the north and east. These observation wells were drilled at 8” diameter to full depth and completed with 4” slotted PVC casing and gravel pack. At test production well sites P2 and P3, the same configuration was used, except the observation wells were doubled at each locality and drilled to depths of 28 m and 40 m with screens 0-27 m and 29-39 m (P2), and drilled depths of 13 m and 38 m with screens 0-12 m and 15-38 m.
Two deep test production wells, PD1, adjacent to CD01, and PD2, adjacent to CD06 were also completed at a diameter of 8” and depth of 200 m. Wells CD01 and CD06 were completed with slotted plastic piezometers to enable their use as observation wells during subsequent pumping tests.
Initially, step discharge tests were undertaken with increasing flow rates to determine the well efficiency, which in all cases was above 87%, indicating the development had been effective.
Constant rate tests started on the August 25, 2010, and ran through until January 26, 2011, when they were stopped as a result of surface water flooding throughout the Salar. This represented a period of 154 days, or just over 5 months and provided a high degree of confidence that pumping rates and brine quality can be maintained in the long-term, which has been confirmed by production to date.
7.9 | Production Wellfield Installation 2012-2013 |
Two production wellfields were installed between 2012 and 2013 for the initial project development. The northern wellfield comprised 16 wells and the southern field four wells, all drilled to 200 m with rotary drilling and installed as production wells. Five additional monitoring wells were installed within and around the production wellfields, in addition to monitoring wells installed around the edge of the salar.
7.10 | Deeper Test Production Wells 2014 |
In 2014 it was decided to drill a test production well in the southwest of the salar to evaluate the sediments below 200 m. The initial test production well (P301) was highly productive, and a deeper, larger diameter well (P302) was subsequently drilled at another site to 323 m, resulting in a flow rate of 30 l/s.
Olaroz Lithium Facility
SEC Technical Report Summary
These wells were subsequently put into production and the positive results have developed an improved understanding of the salar geology and supported further deeper drilling to supply the expansion. These wells have been in production since 2014 and were drilled with the rotary method. Wells were subject to step tests and constant rate tests prior to entering production.
7.11 | Drilling |
Drilling is important to provide representative high-quality samples of the sediments hosting brine, to provide representative samples of the brine itself and to provide samples with sufficient spacing to support different levels of resource estimation. Obtaining representative porosity and brine samples presents several challenges. To supplement information from drilling SDJ has a policy of geophysically logging all drill holes, to maximize the amount of information collected. Drilling has been conducted in the Olaroz-Cauchari basin since 2008, with drill holes by SDJ and adjacent property owners (formerly Advantage Lithium) and Lithium Americas Corp/Ganfeng (LAC). In the Olaroz-Cauchari area there have been approximately 165 wells or piezometers installed (Figure 7-15).
7.11.1 | Exploration Drilling |
Three exploration drilling campaigns were previously carried out at Olaroz. Initial drilling consisted of shallow (60 m) diamond drilling in 2008. This was followed by the drilling conducted at Olaroz in 2010/11 of 19 holes with a sonic rig drilling holes to 54 m and six diamond holes drilled to 200 m, as this is generally beyond the capacity of sonic drilling. A third drilling program in 2014 involved the drilling of two rotary holes that were installed as test production wells to a maximum depth of 323 m.
Sonic drilling conducted in 2011 has the advantage that it is “dry” and does not require drilling lubrication. Other methods of drilling require the use of fluid (in salars brine) for lubrication and to carry drill cuttings to the surface. However, the use of drilling fluid causes difficulties sampling brine and can result in contamination of formation brine during sampling. During the 2011 sonic and diamond drilling brine and specific yield samples were collected every 2 to 3 m and a maximum of every 6 m. For the diamond drill holes to 200 m depth brine and porosity samples were collected approximately every 3 to 6 m, depending on hole conditions. This information was used to develop the 2011 resource estimate to 200 m depth.

7.11.2 | Production Well Drilling |
Production holes have been drilled with rotary drilling equipment, as this method is well suited to the installation of the larger diameter pipes and screens that are required for production wells, compared to the narrow diameters of diamond drill holes used for exploration and obtaining porosity and brine samples. There have been two major drilling programs installing production wells. The first of these was from 2012-2014, with the installation of production wells to 200 m depth, and several holes to greater than 300 m. This drilling was followed by the extension of several 200 m holes to 350 m depth and drilling of another hole to 450 m depth, all with rotary drilling equipment. This was followed by the ongoing expansion drilling program, commencing in 2019 and continuing, with the installation of production wells up to 650 m deep (Figure 7-16).
The Olaroz expansion program was designed to include both installation of production wells and drilling of diamond drill holes, which would then be installed as monitoring wells. Due to the complication of logistics related to Covid-19 distancing and limited site accommodation the planned number of diamond exploration and monitoring wells has not been completed and the installation of production wells was also subject to some delays.
The outcome of this situation is that the geological interpretation and sampling has relied on the installation of the new production wells for deeper information.
Traditionally sampling of brine in salars has relied on collecting samples over discrete intervals (typically with a separation from 3 to 12 m) by packer sampling or using a bailer device to purge fluid from the hole prior to sampling, allowing collection of a representative sample of brine due to inflow of formation brine into the well and sampling device. The complication with this methodology is that significant drilling fluid enters the sediments around the hole and during purging it may not be possible to remove all this fluid prior to collecting a representative brine sample. Fluorescein tracer dye can be used with drilling fluid, so that drilling fluid can be detected by the presence of dye when samples are taken. For the limited diamond drilling completed in the recent diamond drilling Fluorescein has not been used.
The installation of production wells involves widening the initial pilot hole and flushing the hole before the installation of well casing and screens. A gravel pack is added around the well, to minimize the amount of fine material entering the well. The well is then developed by using a jet of high-pressure air against the filters, allowing the gravel pack to settle in place and removing fine material from the well. A swab device is also used to clean the hole and gravel pack. Following use of these devices a pump is installed in the well and pumped to clean fine material from the hole. Once the pumped brine is confirmed to be free of suspended sediments the well is allowed to equilibrate before undergoing pumping tests to confirm the hydraulic characteristics of the well. For individual wells and drilling contractors’ procedures varied for well development.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 7-16 – Installation of filters in a production well at Olaroz.
Screens are typically installed over long vertical intervals in wells, as outside the high permeability sandy units the sediments constitute a “leaky” package of sediments that liberates brine from the thick sequence of sediments. The brine extracted during pumping comes from different depths in a well is an averaged composition, which is influenced by the permeability of the host sediments, with higher permeability sediments contributing relatively higher flows. Brine extracted from wells has shown minimal variation since the start of pumping on Olaroz in 2012, with the variability on the scale of laboratory uncertainties.
Olaroz Lithium Facility
SEC Technical Report Summary
Because of delays with diamond drilling and sampling and the difficulties of collecting brine samples in diamond drill holes to 650 m, assays from the pumped wells to 650 m deep, have been used as part of the resource estimate. Historical diamond drilling to 200 m depth showed the coefficient of variation between lithium in brine samples is low, and consequently use of brine results from production wells is considered reasonable, particularly given the history of pumping and production at the site.
7.11.3 | Shallow Monitoring Well Installation |
Shallow monitoring wells were installed around the borders of the salar to provide information on the depth of and variability in the depth to the water table. These monitoring wells were installed to evaluate seasonal variability (Figure 7-17) in the water table relative to possible long-term changes related to pumping.

7.11.4 | Installation of Expansion Wells (2019-2022) |
Installation of deeper production wells for Stage 2 commenced in 2019 and was completed in late 2022. These wells were installed to 650 m deep in the east of the salar and 450 m in the center and west of the salar. Wells were installed using rotary drilling. Monitoring wells are being installed in diamond drill holes around these new wells. Details are provided below.
Olaroz Lithium Facility
SEC Technical Report Summary
7.11.5 | Drilling Density |
The original production wellfields have been constructed with a one-kilometer space between drill holes to 200 m depth. The expansion drill holes are filling the area between the two wellfields and extending further to the west and south. These wells are installed on a nominal one kilometer spacing, as a continuation of the historical drilling. These holes are drilled at a closer spacing than that recommended by Houston et. al., 2011, with regards to Indicated and Measured hole spacings of five and three kilometers respectively in immature salars.
7.11.6 | Diamond Drilling and Sampling |
A limited amount of diamond drilling was completed for this resource update, due to logistical challenges associated with Covid-19 (principally a limitation of on-site accommodation). Three diamond holes were completed along the eastern boundary of the Olaroz properties to a depth of 650 m. The holes were drilled as HQ diameter diamond holes, with HWT size casing accompanying the drilling of the diamond holes, to maintain hole stability and facilitate brine sampling.
Cores were recovered in 1.5 m long lexan polycarbonate tubes, which were pumped from the core barrel with water, to recover the core tube. The lexan tube was capped immediately following recovery of the core and stored in core boxes. Samples of core for the laboratory were cut from the base of core runs using a battery powered angle grinder. The laboratory sub-sample was 30 cm long, retained in the polycarbonate tube, and sealed with plastic caps, which were sealed in place with tape, to minimize seepage of brine from the cores. Cores were labelled with the hole name and depth range and sent by courier to the porosity laboratory.
The location of the recent diamond holes drilled in this program is presented in Figure 7-1, along with the location of production wells. Historical diamond holes are shown on Figure 7-2, with production wells.
Brine samples were collected using a packer system during the drilling of the three diamond holes. The packer device was lowered into place in the sediments and inflated using nitrogen gas to expand the packers against the walls of the hole. The space between the packers and the sampling line to the surface was then purged of brine, with three volumes of the packer and sampling line purged, with increased purging required as sampling progressed to greater depths. Sample parameters were monitored during the purging, to establish when parameters such as total dissolved solids and density stabilized. Samples were taken after different purge times and compared to evaluate how values stabilized.
Once this stage was reached, triplicate samples were collected for laboratory analysis and storage. However, despite these procedures it was not possible to reliably purge the packer space sufficiently to allow inflow of uncontaminated brine from the hole walls. Because diamond drilling uses significant volumes of drilling fluid this fluid infiltrates the walls of the hole and when samples are taken returns to the hole. The fluid used for drilling was surficial brine taken from a trench in the north of the salar, noted to consistently have significantly lower lithium concentrations than historical sampling in the vicinity of the three diamond holes. Consequently, brine samples from these three diamond holes were not used in the resource estimate.
Olaroz Lithium Facility
SEC Technical Report Summary
Core recovery for the three recent diamond drill holes DDH-02, DDH-04 and DDH-17 was between 86.1 % and 88.6 %. This is higher than historical diamond drilling, which covered a larger spatial area and is summarized in the historical exploration section. Lithium concentration is independent of the core recovery, as it is hosted in brine in sediment pores. Porosity from cores is checked against downhole BMR specific yield measurements.
7.11.7 | Rotary Drilling – Expansion Holes |
Rotary drilling was conducted with conventional tricone rotary drilling equipment, with pilot holes typically drilled and subsequently reamed out in one or more passes to allow the installation of casing with screens of 10- or 12-inch internal diameter. Holes were typically installed with multiple screen intervals in the upper section of the hole and blank sections to act as chambers for the submersible pump. Drilling was carried out using brine as drilling fluid, to lift cuttings from the holes. Drilling details are outlined below:
● | Pre-collar – typically drilled to 12 m and installed with a diameter of 20 inches. |
● | Pilot hole – typically 8.5 or 9 7/8 inches. |
● | Reaming of the hole to progressively larger diameter – typically with 12-, 14.5- and 17-inch tricone bits. |
● | Installation of casing and screen with a diameter of 10 inches for 650 m deep holes and 12 inches for 450 m deep holes. |
● | Once holes were reamed to the final diameter they were flushed and cleaned, prior to lowering in the casing and screen installation (Figure 7-18). The location of the screens was selected based on the geological observations from the well cuttings and the geophysical logging of holes, identifying areas of higher porosity and permeability. Wells were installed with Johnson wound wire screens, to maximize the screen area and inflows to the well. |
● | For the 450 m deep wells gravel pack was installed from surface. For the deeper 650 m deep wells pre-pack filters were part of the well installation, to simplify the process of well completion. Wells 650 m deep are installed with an upper 12-inch diameter section to a depth of 150 to 200 m, with a reduced diameter below these depths. |

● | Once installed with gravel pack the wells were developed by the use of a swab and jet, to settle the gravel pack and remove fine material from around the gravel pack and in the well over a period of days to weeks. Once cleaning of the well was complete, test pumping and surging of the well was undertaken, to complete the process of cleaning the well. Once the well was cleaned it was allowed to equilibrate before step and constant rate tests were undertaken on the well to determine the hydraulic characteristics and to select the appropriate pump for long term production. |
● | The original northern and southern production wellfields were installed with a single diameter of 10 inches, to a depth of 200 m. |

7.11.8 | Comments on the Nature and Quality of the Sampling Methods |
Each of the sampling methods has advantages and disadvantages. One of the strengths of Olaroz is that different sampling techniques have been used at different periods of time.
● | Sonic drilling has the advantage of not requiring drilling fluid, which ensures samples are not contaminated with drilling fluid. Brine samples were collected with a bailer device from brine inflowing into the bottom of the rods, at the bottom of the hole. Core samples were removed by recovering the core barrel with the porosity samples. |
○ | Brine sampling from the 2011 drilling is considered high quality for this reason. |
○ | Porosity samples from the 2011 drilling are also considered to be high quality. However, sonic drilling was only conducted to 54 m, due to the limited capacity of this drilling methodology. Samples were analyzed in the highly reputable British Geological Survey Laboratory. |
● | Diamond drilling has the advantage of having much greater depth potential than sonic drilling. However, because diamond drilling requires drilling fluid there is the potential for contamination of brine samples by drilling fluid. |
○ | Diamond drilling brine samples were taken with a bailer in the original 2011 program. Subsequent to this they have been collected with double packer equipment, that is designed to isolate the sample interval and exclude fluid from surrounding areas. These samples are considered moderate to high quality. Samples were reviewed carefully for potential contamination and suspect samples for reasons of changes in brine chemistry and density. |
○ | Porosity samples were used for specific yield measurements at the Geosystems Analysis laboratory in Arizona. This laboratory has extensive experience analyzing samples for brine explorers. |
○ | The diamond holes (and all rotary holes) from 2018 onward were geophysically logged. This provides an extensive high quality data set to be used for comparison with the laboratory data set. With reasonable correlation with laboratory data over the geological units. Individual results for samples are more variable. The BMR logging provides information every 2 cm, so provided extensive data for resource estimation. |
● | Rotary drilling was used to install production wells. These were installed in the Northern and Southern Wellfields prior to the start of brine production in 2013, where holes were drilled to only 200 m. Subsequent rotary drilling for the Stage 2 production was conducted with holes between 400 and 750 m deep, but typically 450 m in the western part of the infill drilling conducted between the Northern and Southern Wellfields. Rotary drilling provides poor quality geological samples. This was compensated for by running BMR geophysical logs, as well as conductivity, resistivity, spectral gamma, caliper, and televiewer logs of these holes, to maximize the information collected. |
Olaroz Lithium Facility
SEC Technical Report Summary
○ | This extensive geophysical information allowed confident correlation between drill holes and for the installation of filters for definition of the production zones. |
○ | Brine samples were not collected from these holes over intervals, because the drilling method requires drilling of large diameter holes, which are unsuitable for the use of packer equipment. |
○ | Brine samples were collected as composite samples from brine inflow through the different screen intervals in the holes. Because changes in lithium concentration are generally gradual laterally and vertically within salares the composite brine provides an average for the interval where screens are installed. This concentration is considered sufficiently reflective of the formation in which the wells are installed to allow resource classification based on this information. |
○ | Information from pumping tests conducted on the Stage 2 wells prior to entering production has been reflected in the ongoing production from these wells, some of them since 2019. |
In summary, sampling techniques for brine and specific yield are considered to be of generally high quality and suitable for resource estimation.
7.11.9 | Geophysical Logging of Holes |
Diamond drilling was undertaken with standard diamond drilling equipment. Once drill holes reached their final depth the holes were geophysically logged in the open hole with a number of geophysical tools to maximize the collection of data in each well. Geophysical tools used include natural gamma, and resistivity, useful for distinction of halite and clastic layers, spontaneous potential, conductivity and temperature, ultrasonic caliper (for evaluating washouts in the hole) and borehole magnetic resonance (BMR).
The geophysical tools collect information on a 1 cm to 5 cm spacing, providing extensive information for geological interpretation. The logs provide important information on sections of the hole where core may not be recovered – often the intervals with highest specific yield and permeability.
Gamma rays are emitted by uranium, thorium and potassium minerals in sediments, the log typically responds to clay minerals and volcanic horizons. Evaporitic minerals such as halite and gypsum have a very low radioactive mineral content and can usually be identified by their low count rate. The gamma log is a useful tool for identifying certain types of lithology and for correlating beds across multiple wells. Spectral gamma logs provide greater differentiation, for correlation of units with different mineral content.
The BMR tool was developed by the oil industry for in-situ measurements of porosity and permeability. This technology has been miniaturized for use in diamond drill holes and water wells. The BMR60 tool is a 60 mm diameter tool that was run open hole in the HQ diamond drill holes, along with the other tools. For the larger diameter production wells, the 90 mm diameter BMR90 tool was run in the pilot hole, together with the other tools. From these profiles of the holes the BMR tool provides information on the total porosity, drainable porosity (specific yield) and permeability.

SEC Technical Report Summary
Borehole magnetic resonance is a unique measurement that responds to both the volumes of fluids present in a rock, and the geometry of the pores in which this fluid resides. As such, it is a powerful addition to any drillhole geophysical characterization aimed at evaluating the storage and flow capacity of subsurface formations. A modern BMR tool consists of two major components, a set of permanent magnets that create the static magnetic field, and an antenna that creates the transient electromagnetic field.
The echo decay train measured is a function of the volumes of fluids undergoing relaxation at different rates (T2’s) within the volume of rock being investigated. The purpose of BMR data processing is to extract this underlying distribution of the volumes of fluid decaying at the various relaxation rates, known as the T2 distribution. The measured echo decay train is treated as resulting from multiple volumes of fluid, each undergoing relaxation at a particular rate, with the measured decay being the sum of these individual decays. Through the tool calibration, these amplitudes are translated directly into pore volumes. The simplest application of the tool is to use a T2 cut-off to separate bound water (in small pore spaces and held by capillary forces and as clay bound water) and free water, which can be drained by pumping.
The BMR tool allows definition of the total porosity of sediments (Pt), the specific yield porosity (Sy) and a derivation of permeability derived from the porosity data. There are various models for the derivation of permeability, with the Timur-Coates model the most common.
The Borehole Magnetic Resonance tool was designed and built in Australia to operate in highly saline environments like salars. The tools are factory calibrated in Australia and maintained regularly by the service provider.
7.11.9.1 | Borehole Magnetic Resonance Data |
The BMR tool used for the drilling campaign is purpose built for logging of exploration diameter drill holes. The tools are factory calibrated in Australia and maintained regularly by the service provider. The data acquisition and processing methodology gives information on the total porosity, specific yield (drainable porosity), specific retention and provides a computation of permeability and hydraulic conductivity with a vertical resolution varying from 5-15 cm providing much more information than individual core samples analyzed for porosity every 3 m.
Porosity values from the GSA laboratory sampling were compared to the BMR porosity logs. While some differences are noted the general ranges of porosity values for the different hydro-stratigraphic values are considered comparable.
Salar sediments often display short range vertical variability (within a meter or over meters to 10’s of meters) due to changes in the depositional environment over time. This results in vertical and lateral changes in specific yield. BMR drainable porosity (Specific yield) measurements may be lower than corresponding laboratory measurements as cores may be disturbed during sampling and transportation to the laboratory and not reflect the natural in-situ state.
Olaroz Lithium Facility
SEC Technical Report Summary
Salar sediments are subject to compaction as they are buried with compaction generally resulting in a decrease in total porosity and specific yield with depth although not all sediments are affected equally by compaction.
Holes drilled for the original feasibility study were logged with a neutron tool as borehole magnetic resonance technology was not available to the lithium industry in 2011. The neutron tool measures the hydrogen index of the formation (solids and brine). Neutron porosity is the result of applying a simple equation using the neutron measurement and two parameters. For the 2011 Resource neutron log data was compared with laboratory data to develop an algorithm for porosity across the resource area. BMR technology is considered more accurate for porosity definition in the salar environment and has now superseded use of neutron logs.
There are some differences observed between porosity measurements made with the neutron and BMR logs through comparable sediments. The specific yield of this updated resource is lower than the 2011 Resource, partly due to differences in depth and geological intervals intersected and partly due to a reduction in comparable porosity values.
It is noted that the original drilling to 200 m intersected only the upper part of the halite layer. The ongoing drilling for Stage 2 has defined the full thickness of the evaporite/halite unit UH4. This unit has a generally lower porosity than overlying and underlying clastic sedimentary units due to the compaction of halite with depth. Similarly clastic units also undergo some compaction with depth and consequently the overall porosity of the newly estimated resource is lower compared to the original resource in the upper 200 m of the salar.
7.11.10 | Brine Sampling |
Drilling has confirmed the previously defined lateral zoning in brine concentrations broadly continues at depth, and it is likely that brine will continue to the base of the basin. As drilling has progressed towards the south it has confirmed the previous observations of flow rates in this area, with new wells in the south of the properties producing at 70 l/s and 629 mg/l (E26 December 2022 average), 54.7 l/s and 539 mg/l (E24 December 2022 average) and 30.3 l/s and 660 mg/l (E22 December 2022 average). The new production wells are producing at concentrations from 542 mg/l (E09) to 786 mg/l Li (E08) and flow rates from over 10 l/s to over 60 l/s (E09 and E26), providing samples representative of the aquifers intersected by these wells. Brine samples are available from the weekly analysis of samples from the original (PP series) and expansion (E series) production wells and from check samples in external laboratories.
Brine samples from historical exploration drilling were analyzed in a number of commercial laboratories, principally the Alex Stuart laboratory in Mendoza, Argentina. Since construction of Olaroz brine samples have been analyzed in the Olaroz site laboratory, with check samples sent to the Alex Stuart laboratory in Jujuy, Argentina, with analysis of duplicates, standards, and blank samples. Results are considered to be sufficiently robust for resource estimation.
Olaroz Lithium Facility
SEC Technical Report Summary
The resource was estimated using historical sonic and diamond drilling, recent diamond drilling and results from production wells, to maximize use of the available information. SDJ has operated production wells installed to depths of between 300 and 450 m for up to 5 years and from 650 m for 3 years. These provide important production history and continuity of brine concentration over this period to support the updated resource estimation to 650 m.
7.11.11 | Pumping Tests |
7.11.11.1 | Variable Rate Tests |
Once wells were installed and cleaned pumping tests were undertaken. These consisted of an initial short term variable rate (step) test, to assess the capacity of the well over a period of up to nine hours (Figure 7-19). Once this test was completed the rate for the constant rate test was determined. Wells do not directly have observation wells, as they are part of production wellfields. The monitoring well network will be updated to monitor pumping from the new production wells.

7.11.11.2 | Constant Rate Tests |
When the well static water level had recovered the constant rate test was completed for a minimum period of up to 48 hours, pumping. The brine was pumped directly to the initial receiving tanks, with each well connected to the site electrical network.
Pumping test results were analyzed with standard pumping test methodologies (Figure 7-20) and the hydraulic conductivity and transmissivity at the well was calculated using Theis, Neumann, and Jacob methodologies. Hydraulic conductivity, transmissivity and storability are summarized in Table 7-4.

7.11.11.3 | Ground Water Levels |
Groundwater levels were measured in initial exploration of the salar, with the water table within 1 meter of surface across the salar surface. Off the salar, the groundwater level in the alluvial fan sediments is deeper, as the topography rises around the salar and where fresh to brackish water is present.
SDJ has established a monitoring well network around and within the salar, from which regular information is collected on changes in water level (Figure 7-21 above). Hydrographs from the monitoring network around the edges of the salar generally show there is seasonal decline in the groundwater level due to discharge to the salar and evaporation, with recharge from seasonal summer rainfall (and possibly snow melt) resulting in a rise in the groundwater level. These dynamic changes will depend on yearly and long-term rainfall and snow patterns and could potentially be influenced by pumping activities.
Within the salar pumping has generated a drawdown cone that is centered around the northern and southern wellfields, which appears to have developed a stabilized drawdown level.

7.11.11.4 | Water Balance |
In most enclosed basins, in absence of any major groundwater abstraction, it is assumed the long-term water balance is in equilibrium, with groundwater recharge from precipitation equal to the groundwater discharge and evaporation. Groundwater recharge in high desert basins is generally difficult to quantify, due to scarcity of precipitation measurements (liquid and solid) and the uncertainties in the soil infiltration and potential sublimation rates, and runoff coefficients.
Olaroz Lithium Facility
SEC Technical Report Summary
Groundwater recharge was estimated from groundwater inflow into the salar from surrounding sub-basins for which infiltration was calculated through a surface water model developed by consultants NAPA.
Groundwater discharge in enclosed basins takes place through evaporation, which is a function of soil type (grainsize/permeability), depth to the phreatic level, water (brine) density and climatic factors (both seasonal and longer term). Soil evaporation rates were determined as a function of these parameters using evaporation domes and data collection from shallow auger holes in December 2018 in Cauchari.
With this information three evaporation curves were established with respect to depth, for the nucleus, marginal and alluvial zones. This data was applied to equivalent areas of the Olaroz salar by consultants NAPA, in order to estimate the long-term evaporation, there. The evaporation data was then used to estimate the natural water losses from the basin and how they compare with water inputs. The NAPA model has a difference of less than 2% and is considered to adequately represent the basin water balance.
7.11.11.5 | Commentary on the Determination of Groundwater Parameters |
Surface water information was obtained by gauging the few surface water inflows into the basin in the Rio Rosario in the north of the basin and Rio Ola in the Archibarca alluvial fan in the west of the basin. This was done throughout the year, to establish the variability of flow through periods of different climatic conditions. Surface water physical parameters (pH, EC, TDS, temperature) were measured in the field as well as flow. Samples were sent for analysis in the company laboratory, for the determination of the concentration of different elements.
Groundwater characteristics were evaluated during and after the drilling process. This consisted of measuring the physical parameters (pH, EC, TDS, temperature) from samples taken during sonic and diamond drilling. These samples were sent for analysis in external independent laboratories and for the diamond drilling in 2019 with analysis of samples in the company laboratory (these samples were not used in the resource estimation). Samples from pumping tests and production from the wells were analyzed in the company laboratory, with QA/QC check samples analyzed in an independent certified laboratory (Alex Stuart Laboratories) in Argentina.
The company laboratory uses the Atomic Absorption method to measure lithium concentrations, ICP-OES for the measurement of other elements and different techniques discussed in section 8 for the analysis of anions. The Alex Stuart laboratory used for analyses of brine samples in 2021 and 2022 used the methods outlined in Table 7-5, also using ICP-OES for the analysis of cations, including lithium. Both field duplicates and laboratory prepared standards were used as part of sampling programs. These methods are considered appropriate for the analysis of these elements and interlaboratory correlations are considered to be reasonable and acceptable. Future more extensive use of duplicates and standards and inter-laboratory testing is recommended.

The Olaroz salar sediments are not a classic aquifer sequence. The sediments consist of an upper sequence of interbedded fine-grained sediments (clay, silt) with some sand units and an extensive of halite (common salt) and some evaporite minerals. The sand units within this sequence are highly productive, while the remainder of the sediments act more like a leaky aquitard system than a classical aquifer. The halite units are often massive, compact and produce little flow, unless they are interbedded with sands.
Significantly higher flows are obtained from the UH5 unit, which consists of fine sand units and some gravels, which are classical aquifer materials and highly productive. Low productivity is considered for the halite units.
Groundwater flow was measured by step pumping tests conducted on production wells and by constant rate pumping tests conducted in these wells. Pumping conducted over hours and days is an accepted way of deriving the hydraulic conductivity (the measure of permeability) of the aquifers. With pumping tests conducted with some of the original Northern and Southern well-field production wells and all of the Stage 2 production wells. Pumping tests are considered a more appropriate way of obtaining information on the permeability of the host sediments than samples on core samples, which are representative of local intervals. The pumping tests provide information regarding the productivity of the intervals where screens are installed, which are based on the specific yield and evaluation of the in-situ permeability derived from the BMR geophysical tool.
Olaroz Lithium Facility
SEC Technical Report Summary
Flow rates from the step tests and evaluation of the constant rate tests were used to define the flow rates and productive capacity of each well for long term pumping. The recharge rate was evaluated from consideration of long-term rainfall patterns and evaporation in the salar basin. The groundwater model developed for the salar was based on the results of actual pumping data from 2013 to 2021, consequently the model has a vastly larger series of input data than most salar projects and this is considered to add confidence to the modelling and the outcomes.
7.11.12 | Exploration Target |
It must be stressed that an exploration target is not a mineral resource. However, the resource is open both laterally to the north and south, with lesser potential west of the salar. Further, the gravity survey, used to define the base of the salar, underestimates the thickness of the salar sediments. One deep hole (E1) has been drilled to 1,408 m slightly north of the current Northern wellfield, but to date no Allkem drilling in the Olaroz basin has yet intersected the basement/bedrock.
Laterally, the resource area is defined by the salar surface and property boundaries. Previous limited drilling and geophysical surveys indicate the brine body extends south beneath gravels of the Archibarca alluvial fan to Cauchari (where drilling by Allkem subsidiary South American Salars defined 4.6 Mt of M&I Resources and 1.5 Mt of Inferred Resources in 2019). The gravity survey also supports a large area of >650 m depth in this Northern part of the basin under the Rio Rosario delta and surrounding alluvial fans. Consequently, there is significant potential for future definition of Resources, within the exploration target defined here.
The potential quantity and grade of the exploration target is conceptual in nature, and there has been insufficient exploration to define a Mineral Resource in the volume where the Exploration Target is outlined. It is uncertain if further exploration drilling will result in the determination of a Mineral Resource in this volume.
However, there is a considerable amount of geological knowledge available from drilling, AMT, and gravity geophysics, which gives the company a fair amount of confidence with respect to the exploration target.
The Exploration Target ranges between 14 and 33.6 Mt LCE, depending on the values used for porosity and lithium concentration. Information from third party Lithium Energy Limited, drilling to the northeast of the salar, suggests the stratigraphy defined on the salar continues north beneath the Rosario Delta area, with considerable potential for future brine discovery in the Allkem properties.
The exploration target volume is included within the geological model where the resource is defined, with the same units defined across the model. The model consists of five hydrogeological units overlying the interpreted basement rocks. The Exploration Target is defined around the edges of the model, where there is no or very limited drilling, and consequently much greater uncertainty as to the specific yield conditions of the sediments and the lithium concentration in the sediments. Drilling by Allkem and a third party to the north of the salar has validated the geological model.
Olaroz Lithium Facility
SEC Technical Report Summary
The likely range of specific yield porosity and lithium content has been defined based on knowledge of changes in concentration in this and other brine deposits, with concentrations changing gradually horizontally and vertically. The volume of the exploration target has been based on the distribution of the hydrogeological units within the Olaroz basin and the limits of the property boundaries. The lowest values for specific yield and lithium concentration were multiplied with the volume to generate the lowest likely case of contained lithium. Conversely the highest values of specific yield and lithium concentration were multiplied together to define the highest case.
The exploration target is based on the lateral projection of actual exploration results. The exploration completed to date has been semi-systematic and considerable information is available within the more central portion of the salar, where diamond and rotary drill holes have been completed. Proposed exploration activities consist of future drilling of diamond and rotary drill holes, with down hole logging of holes drilled. It is expected that exploration will be completed over a period of several years.
The ranges of tonnage and grade (or quality) of the exploration target could change as the proposed exploration activities are completed and there are no guarantees that any given area or volume of the exploration target can be converted to Resources.
7.12 | Conclusions |
Exploration on Olaroz has been carried out over an extended period, with drilling on Olaroz commencing in 2009 and the most recent drilling involving the installation of Stage 2 production wells completed in 2022. Over this period drilling depths have evolved from less than 100 m to 650 m depth, with the drilling of one-hole 1,408 m deep.
Exploration has been carried out to a high standard, with a focus on obtaining reliable brine and porosity samples and with the collection of samples with different methods for corroboration of results, where possible. To provide a high-quality data set of specific yield porosity data, down hole geophysics has been used to make measurements of in-situ specific yield, initially with neutron and density logs and more recently with borehole magnetic resonance (BMR) equipment.
Brine samples have been collected by bailer sampling in the upper 200 m, and from pumping tests and production pumping below 200 m. The data collected is considered suitable for estimation of Resources.

SEC Technical Report Summary
8. SAMPLE PREPARATION, ANALYSES AND SECURITY
The following sub-sections detail historical and recent sampling methods that have been conducted to support Olaroz.
8.1 | Reverse Circulation Procedures, Sample Preparation, Analyses and Philosophy |
Ensuring that samples taken are truly representative of the subsurface conditions in the salar is a key consideration for sampling. Collecting truly representative samples is challenging and consequently multiple sampling methods have been used over the life of Olaroz in order to compare results and check they are consistent.
8.1.1 | Sampling and Preparation Procedures |
Diamond drilling consisted of HQ or NQ size cores, with lexan polycarbonate tubes used as liners inside the core barrel to facilitate core recovery and to preserve samples with minimum disturbance for laboratory porosity analysis. Cores were recovered at surface by pumping the lexan tube from the core barrel using water, with a plug separating tube and water. Upon release from the core barrel tight fitting caps were applied to both ends of the lexan tube. The tube was then cleaned, dried, and labelled.
The lower 30 cm of the lexan core was cut from the 1.5 m long core tube using a portable angle grinder. This core sub sample was then capped, and tape used to secure the caps in place and minimize any fluid loss during transportation.
8.1.2 | GeoSystems Analysis Core Testing |
GSA was selected as the primary laboratory for the specific yield (Sy) and other physical parameter analyses conducted on the recent diamond drill cores collected at Olaroz. GSA utilized the Rapid Brine Release method (Yao et al., 2018) to measure specific yield and measured the total porosity with a standard gravimetric technique, drying the saturated sample in the oven.
The Rapid Brine Release (RBR) method is based on the moisture retention characteristics (MRC) method for direct measurement of total porosity (Pt, MOSA Part 4 Ch. 2, 2.3.2.1), specific retention (Sr, MOSA Part 4 Ch3, 3.3.3.5), and specific yield (Sy, Cassel and Nielson, 1986). A simplified Tempe cell design (Modified ASTM D6836-16) was used to test the core samples. Brine release was measured at 120 mbar and 330 mbar of pressure for reference (Nwankwor et al., 1984, Cassel and Nielsen, 1986), which is considered to reflect drainage from coarse- and fine-grained samples respectively.

In addition to specific yield, bulk density and specific gravity were determined on core samples. Table 8-1 provides an overview of the test work carried out by GSA and other laboratories where previous samples and check samples were analyzed.

8.1.3 | Core Sampling Frequency |
Sixty-four core samples were tested from DDH02, DDH04 and DDH17 diamond cores during the most recent drilling program, drilling to 650m deep. Twenty-five of these samples had duplicate core samples analyzed in the DB Stephens laboratory in the USA. A comparison of results between both laboratories is provided in Figure 8-1 and Figure 8-2.
Historically 543 Olaroz samples from 2009 to 2011 were analyzed for total porosity (Pt), with 205 specific yield (Sy) analyses at the BGS research laboratories. Sample frequency with depth for those analyses used in the historical resource estimation averaged 2.8m per sample in the upper 54 m, and 7.1 m per sample in the 54m to 197m interval.

8.1.4 | Laboratories Procedures |
Check samples were sent to the DB Stephens laboratory in the USA to determine the specific yield (Sy) for core plugs taken adjacent to those analyzed by GSA. The Stephens laboratory uses the RBRC test methodology (Stormont et. al., 2011), which was developed by the laboratory. This involves application of a vacuum pressure of -0.25 bars to samples over a period of 24 hours, before the samples are oven dried to determine fluid loss. Quality control using the same method was also carried out on the samples previously analyzed on the Cauchari project. In the Cauchari project the Centrifuge Moisture Equivalent of Soils (Centrifuge, ASTM D 6836-16) method was also used by Core Laboratories (Houston, TX) as a check on the primary sample results by GSA.
A total of 25 core plugs were analyzed and compared with the adjacent samples analyzed by GSA, with results shown in Figure 8-1 and Figure 8-2. It should be noted that salar sediments can show rapid vertical changes in total and specific yield, something that is also observed in borehole magnetic profiles of porosity data. The duplicate core plugs, while sampled from as close as possible to the primary sample, also show some natural variation in grain size and hence porosity and are not identical samples to the primary samples.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 8-1 – Comparison between the GSA and Stephens sample results.
Some systematic differences are noted between the GSA and Stephens data, with the GSA Sy data measured at 330 mbar showing higher values than the Stephens data on adjacent plugs. Most of the samples tested for Sy fall below the 1:1 line, indicating that GSA measured Sy values are often higher than those for the Stephens lab. The GSA 120 mbar data is more closely correlated with the Stephens data.
The longer time the testing is undertaken at the GSA lab (1 week versus 24 hours at the Stephens lab), together with the slight differences in the pressures used in the tests and the natural variability between adjacent samples is believed to explain the differences in results. The GSA technique is considered to measure brine drainage from easily drained more porous materials (like sands) as well as delayed drainage (as observed in leaky aquifer systems) from finer grained sediments. A statistical comparison of results from the GSA 120 mbar testing and the Stephens RBRC testing is presented in Table 8-3. Note the small number of silt samples is likely to influence the comparison between the sample sets.

8.1.5.1 | Diamond Drilling |
In the Olaroz 2010/11 sampling program, when holes were predominantly to 54 m depth, samples for fluid chemistry analysis were taken every 3 m depth interval in all sonic holes and in the 200 m deep diamond drilled holes, where possible. With the original sonic drilling a push-ahead well point with double packers was attached to the base of the rods and inserted into the formation ahead of the well casing advance. The packers sit inside the casing and so affect a seal between the well point and the hole above inside the casing. Bailer tube devices were used for sampling the 200 m deep diamond holes.
Olaroz Lithium Facility
SEC Technical Report Summary
Sampling of brine from the recently drilled diamond holes consisted of extracting brine using a packer device that sealed over an interval of 1.5 to 6 m. This sampling was conducted approximately every 12 meters. However, it was not always possible to take samples, due to limitations with the permeability of the sediments.
8.1.5.2 | Production Well Sampling |
Olaroz has two operating wellfields that were established for Stage 1. Olaroz lithium facility has two operating wellfields that were established for Olaroz Stage 1. Additional wells have been installed for Stage 2, drilled to between 450 and 650 m depth. Samples were collected from the operating wellfield holes and the newly installed Stage 2 wells by collecting bottles of brine from the diversion valve located on each wellhead to allow the regular weekly sampling to be carried out on site. Samples were taken in duplicate and analyzed at the on-site laboratory at Olaroz. Duplicate samples were collected and sent to the Alex Stuart laboratory in Jujuy Argentina for analysis.
Samples were also taken during the constant rate pumping tests conducted on Stage 2 wells when the hydraulic parameters were selected before putting the wells into production. These samples analyzed at the on-site laboratory showed consistent lithium concentrations. Long term pumping of wells from Stage 1 (over a period of up to 7 years) has confirmed the consistent concentration of brine extracted from individual wells over this period.
8.1.5.3 | Sampling Protocol |
At the wellhead, prior to filling, the two one-liter bottles and their caps were rinsed out with a small amount of sample. The sample was then collected in two bottles. In each case all air was expelled from the bottle, the caps screwed tight and sealed with tape. Each bottle was labelled using a permanent marker with the drillhole number and the depth of the sample.
Samples were transferred from the drill site to the field camp where they were stored out of direct sunlight. Before being sent to the laboratory the bottles of brine were labelled with a unique sample number. The hole number and date of collection were recorded in a spreadsheet control.

8.2 | QA / QC Brine Analysis Procedures and results |
8.2.1 | Analytical methods |
The primary laboratory used for analyses following the feasibility study completed in 2011 has been the laboratory that is established at Olaroz. This laboratory is owned and operated by Sales de Jujuy and is used to analyze brine samples from the production wells, evaporation ponds and from the product produced at the plant. The laboratory sends samples to other independent laboratories for periodic verification using round robin methods, to evaluate the performance of Sales de Jujuy analytical techniques and the results. The Olaroz laboratory has been used to analyze all the brine samples from production wells that have been used in the resource estimate. The laboratory also analyzed samples from diamond drill holes. Duplicate samples were analyzed at the Alex Stuart laboratory in Jujuy.
The Alex Stewart laboratory in Jujuy, Argentina was selected as the secondary laboratory to conduct check assaying of brine samples from wells and diamond drill holes collected for the resource estimate. This laboratory is ISO 9001 accredited and operates according to Alex Stewart Group standards consistent with ISO 17025 methods at other laboratories.
The SGS laboratory in Salta, Argentina (SGS) was used along with the Alex Stuart laboratory as part of the independent comparison process by the Olaroz laboratory.
Table 8-4 lists the suite of analyses provided by the Olaroz lab and Alex Stuart, the methods used and detection limits. It is noted that there are some differences in the methods between labs and in particular the Olaroz laboratory uses Atomic Absorption for analysis of lithium and potassium.

8.2.2 | Quality Assurance and Quality Control |
8.2.2.1 | Analytical Controls 2010/11 Diamond Drilling Program |
A full QA/QC program for monitoring accuracy, precision and potential contamination of the entire brine sampling and analytical process was implemented in this previous diamond drilling program. Accuracy, the closeness of measurements to the “true” or accepted value, was monitored by the insertion of standards, or reference samples, and by check analysis at an independent secondary laboratory (Alex Stuart in Mendoza, Argentina). The details of the quality control program are provided in the NI43-101 report prepared by Houston and Gunn (2011).
Precision of the sampling and analytical program, which is the ability to consistently reproduce a measurement in similar conditions, was monitored by submitting blind field duplicates to the primary laboratory. Contamination, the transference of material from one sample to another, was measured by inserting blank samples into the sample stream at site.
Blanks were barren samples on which the presence of the main elements undergoing analysis has been confirmed to be below the detection limit.
The results of the analyses of the standards are summarized in the NI43-101 report prepared by Houston and Gunn (2011). Results were within one standard deviation of the standard sample, except for Cl and K, which were marginally outside. Lithium values were 1.5% and 0.4% of the standard values for the two standards used.
8.2.2.2 | Analytical Controls 2021 Diamond Drilling Program |
A total of 55 primary brine samples were analyzed from the three diamond core holes (DDH02, DDH04, DDH17) drilled as monitoring wells, to a depth of 650 m, as part of the Stage 2 expansion. These holes are in a spatially localized area, drilled along the eastern property boundary. Considering the limited spread of these holes along the eastern property boundary and difficulties obtaining representative brine samples, these drill holes were not used in the resource estimation. Instead, brine samples from the production pumping wells (E-Series) were analyzed and utilized in the resource estimate. The PP series production wells and the expansion E series production wells were sampled upon completion. Analytical controls included:

8.2.3.1 | Standards |
Two standards, 2G and 3G, are prepared and used by the SDJ Olaroz laboratory on a regular basis. These were used for external laboratory analyses, where standards are sent to different laboratories to compare results. These standards were sent to the Alex Stuart laboratory in Jujuy, Argentina and the SGS laboratory in Salta, Argentina to check the results of standards. The results of standards from the round robin evaluation between laboratories are presented in Table 8-5 and in Figure 8-3.
Figure 8-3 – Standard results from the round robin analysis of standards at different laboratories.
Performance of standards is presented in Figure 8-4 and Figure 8-5. The standards were prepared in the Olaroz laboratory and were not independently prepared. It is difficult to obtain independent standards from sources other than the independent laboratories which were used to check results from the Olaroz laboratory, due to tight controls on chemicals in Argentina. Analyses by SGS were generally more variable than those of Alex Stuart.

8.2.3.3 | Interlaboratory Duplicates |
Interlaboratory duplicates from the three diamond drill holes were analyzed in the Alex Stuart laboratory in Jujuy in addition to the primary samples analyzed in the Olaroz laboratory. The results are presented in the following Figure 8-6. These show there is a slight bias between the two laboratories, with higher values for lithium, potassium, magnesium, and boron from the Olaroz lab. The Olaroz laboratory used Atomic Absorption spectroscopy for analyses of lithium and potassium, to minimize interference between different elements, whereas the Alex Stuart laboratory uses ICP-OES. Overall, the comparison is considered acceptable, although the differences between the laboratories are noted and a high portion of QA/QC samples are recommended for future analysis, in addition to more regular analysis in independent external laboratories.
Interlaboratory duplicates consisted of a batch of 24 primary samples, with 5 internal duplicates analyzed at the Sales de Jujuy laboratory. The 24 samples were analyzed in the Sales de Jujuy laboratory and in the Alex Stuart laboratory in Jujuy. The results are presented in the following Figure 8-7. These show there is a slight bias between the two laboratories, with higher values for lithium, potassium, magnesium, and boron from the Olaroz lab.

8.2.3.4 | Ionic Balance |
The ionic balance is a measure of the relative imbalance between anions and cations. The ion balance should ideally be as close to zero as possible, although results of less than 5% are generally considered acceptable. Figure 8-8 shows the Olaroz lab ionic balance over the extended period from 2017 to 2021 has almost all samples below 6%.
Blanks are not routinely used. The difference in concentration between blank and brine with the optimized calibration of the spectrometer makes results from blanks less reliable.

An additional 24 primary brine samples were analyzed from new wells put into production since 2021, earlier E series holes installed for the expansion and some existing PP production holes. These analyses provided a check on the average lithium concentrations for pumping of these holes, that were used for the resource estimate. Samples were selected to include all the E series holes (15 in total) and a selection of PP series holes from the original northern and southern wellfields.
As part of the QA/QC undertaken five field duplicates were included in addition to the 24 primary samples. Four standard samples (2 each of the 2G and 3G standard) were also included. All samples were analyzed in the on-site SDJ laboratory and the independent Alex Stuart commercial laboratory in Jujuy. Results are provided in the figures and tables below.
8.3 | Sample Shipment and Security |
Brine samples at the exploration stage in 2009 to 2011 were collected by company personnel and transported to the Alex Stuart laboratory in Mendoza by commercial courier companies. The samples were placed in cooler boxes for transportation and were sealed with plastic tape to secure them during transportation and so they were not opened by unauthorized parties. The samples were accompanied by a chain of custody forms, which were also sent by email to the laboratory. The laboratory confirmed reception of the samples to the company. Porosity samples were treated in a similar way but were packed inside PVC tubes to minimize disturbance and packed in boxes with packing materials to minimize disturbance and possible damage to the samples. Samples were accompanied by a sample list. Receipt of the samples was confirmed by the British Geological Survey laboratory who analyzed the samples.
Since the initial exploration program and resource there has been an onsite laboratory operating at Olaroz. The bulk of analyses since 2011 have been transported by company personnel directly to this laboratory, using sequential sample numbers applied to samples in identical plastic bottles. Samples were submitted to the lab as blind samples, without reference to the well number, for evaluation of the brine chemistry.
Results were provided to the Hydrogeology personnel by email. Check sampling rounds have been conducted since this time, with samples sent to the Alex Stuart laboratory in Jujuy, Argentina, delivered by company personnel to the laboratory. Receipt of samples was confirmed, and results were provided by the laboratory in electronic format.
Olaroz Lithium Facility
SEC Technical Report Summary
Porosity samples were packed as described above and sent to the GSA laboratory in the USA, where receipt of samples was confirmed, and the sample quality checked to assess whether they were adequate for analysis.
8.4 | Core Handling Procedures |
The core samples were prepared for specific yield testing by the Geosystems Analysis laboratory (GSA) in Tucson, USA, using a 5 cm subsample cut from the base of the core liner that was sent to the lab. All samples were labelled with the hole number and depth interval. Porosity samples were transferred to the site camp and stored, prior to cutting sub samples for laboratory analysis. Prior to sending each sample was wrapped in bubble plastic to prevent disturbance during transportation. A register of samples was compiled at the Olaroz site to control transportation of samples to the laboratory. Samples were sent by courier to the GSA laboratory.
8.5 | Specific Gravity Measurements |
GeoSystems Analysis core testing (GSA) was selected as the primary laboratory for the specific yield (Sy) and other physical parameter analyses conducted on the recent diamond drill cores collected at Olaroz. GSA utilized the Rapid Brine Release method (Yao et al., 2018) to measure specific yield and measured the total porosity with a standard gravimetric technique, drying the saturated sample in the oven.
The Rapid Brine Release (RBR) method is based on the moisture retention characteristics (MRC) method for direct measurement of total porosity specific retention (Yao, T., Milczarek, M., Reidel, F., Weber, P.G., Peacock, E., and Brooker, 2018. Proceedings of Mine Water Solutions 2018. June 12-16, 2018, Vancouver, Canada) and specific yield (Sy, Yao et. Al., 2018; Cassel and Nielson, 1986). A simplified Tempe cell design (Modified ASTM D6836-16) was used to test the core samples. Brine release was measured at 120 mbar and 330 mbar of pressure for reference (Nwankwor et al., 1984, Cassel and Nielsen, 1986), which is considered to reflect drainage from coarse- and fine-grained samples respectively.
In addition to specific yield, bulk density and specific gravity were determined on core samples. Table 8-1 provides an overview of the test work carried out by GSA and other laboratories where previous samples and check samples were analyzed.
Table 8-2 shows the porosity results by lithology type from recent and historical porosity measurements at Olaroz and the Cauchari properties owned by Allkem.
Olaroz Lithium Facility
SEC Technical Report Summary
8.6 | Historic Drill Holes |
Specific yield samples were historically (2010/11) tested at the British Geological Survey (BGS) in the UK, with testing of samples at an on-site laboratory in Olaroz for total porosity and testing of duplicates by the BGS. Historically samples from Allkem’s Cauchari project were also tested by the BGS in 2011 and more recently in 2017/18 samples were analyzed at the GSA laboratory from the extensive drilling program conducted.
The BGS determined specific yield using a centrifugation technique where samples are saturated with simulated formation brine and weighed. They are then placed in a low speed refrigerated centrifuge with swing out rotor cups and centrifuged at 1,200 rpm for two hours and afterwards weighted a second time. The centrifuge speed is selected to produce suction on the samples equivalent to 3.430 mm H2O, which was previously defined by Lovelock (1972) and Lawrence (1977) as characteristic of gravitational drainage.
8.7 | Comments on Sample preparation analysis and security |
Hydrominex Geosience (the QP) considers that samples have been collected in an acceptable manner overall, although QA/QC sampling has been with a low frequency post the exploration program that defined the initial resources. In the 2009-2011 exploration program there was extensive use of QA/QC sampling for brine samples. However, since Olaroz began operations there has been less emphasis on QA/QC sampling and periodic analysis of samples in external independent laboratories.
More emphasis on ongoing QA/QC sampling and analysis, and external independent analysis of brine samples is recommended going forward at the Olaroz operation.
Olaroz Lithium Facility
SEC Technical Report Summary
9. Data Verification
The company has an ongoing QA/QC program where brine samples are collected from the operating production wells weekly and analyzed for the major brine components in the Olaroz site laboratory. These samples are accompanied by QA/QC samples that comprise field duplicate samples, laboratory prepared standards and distilled water blank samples submitted with each batch.
9.1 | Quality Control Program |
The results of the QA/QC samples are evaluated by batch and stored in the Olaroz database. If there are any unacceptable results (i.e., greater than 2 standard deviations), from comparison of samples the samples are reanalyzed and if necessary resampled.
Periodic batches of samples are sent externally to the Alex Stuart Laboratory in Jujuy province and the duplicate, triplicate, standard and blank samples are compared with results from the Olaroz laboratory. Results are considered to be acceptable, with recognition of biases between the laboratories, in part related to laboratory methods.
9.2 | Verification of QC Program |
Mr. Brooker was involved during the original 2010/2011 drilling program at Olaroz, working with the then QP Mr. John Houston. During this period Mr. Brooker reviewed the brine and porosity sample results received and used for the 2011 resource estimate. Mr. Brooker has subsequently verified this assay data for the inclusion in the 2022 updated resource.
QP Mr. Brooker has reviewed the protocols for drilling, sampling, and testing procedures for the Olaroz expansion drilling program. These procedures are essentially the same as for the original 2010/2011 drilling and testing program. Mr. Brooker was previously involved in designing the expansion drilling program and has previously spent a significant amount of time at the Olaroz camp working with the Olaroz team during the implementation and execution of drilling, testing, and sampling protocols.
Due to Covid limitations Mr. Brooker did not visit Olaroz during 2020 and 2021, and was last at Olaroz on November 21, 2022, reviewing drill cuttings from the expansion holes and reviewing QA/QC samples collected for analysis.
Mr. Brooker has reviewed information from the QA/QC programs related to brine sampling and laboratory brine chemistry analysis as well as the laboratory porosity analysis. QA/QC protocols were implemented for the specific yield and brine chemistry analysis programs. Mr. Brooker requested a series of interlaboratory duplicates to be submitted and evaluated as part of data verification procedures.
Olaroz Lithium Facility
SEC Technical Report Summary
No significant issues were found with the results of the brine and porosity laboratory analysis. However, in 2022 some samples were recollected and sent to the on-site and external laboratories, as Hydrominex Geosience (the QP) considered the original samples were not adequately labelled, to avoid doubt about their respective sources.
The diamond drilling and production well programs were not implemented in the planned time frame, due to constraints imposed by managing Covid-19.
It is the opinion of Mr. Brooker that the sampling procedures, security, preparation and analytical procedures and the information received and used for the brine resource estimate is adequate for that purpose.
The employee of Gunn Metallurgy, set forth herein, the QP responsible for mineral processing, metallurgical testing and process and recovery methods was involved with and has reviewed historical test work. He has subsequently been involved conducting periodic reviews of Olaroz’ performance, since Stage 1 entered production. The employee of Gunn Metallurgy set forth herein has sufficiently validated the data for that purpose.
9.3 | Comments on Data Verification |
The employee of Hydrominex Geoscience set forth herein (the QP) is of the opinion that the analytical results delivered by the participating laboratories and the digital exploration data are sufficiently reliable for the purpose of the Brine Resource estimate. Recommendations have been made for a modified QA/QC regime going forward.

10. Mineral Processing And Metallurgical Testing
10.1 | Initial Characterization and Scoping Studies |
The following section is a review of the early testing completed for the purposes of the original Olaroz Project feasibility study. In large part operating results have reflected the findings of this early test work. Very little basic testing has been done since for the obvious reason that full scale operations can be more readily measured and analyzed. However, significant information relating to production performance and consequent efficiency improvements have been gained since 2015 by testing and analysis of:
● | Magnesium precipitation control with lime. |
● | The mode of Li losses in the pond system. |
● | Testing of a range of direct extraction techniques for recovery of Li from raw brine, plant feed, and Li recovery from mother liquor. |
● | Control of sulphate and borate concentrations using calcium chloride. |
● | Impurity removal in the polishing area. |
● | Carbon dioxide recovery from crystallization reactors in the purification circuit. |
● | Testing of various brine heating and cooling systems. |
10.1.1 | Overview |
The brine resource defined at Olaroz on the Olaroz Salar contains soluble lithium, potash, and boron compounds. The economic value of lithium as battery grade carbonate is by far the largest and was the focus of early process development work. As market growth for lithium for the Li-ion battery segment has evolved, the objective has been to produce battery grade products.
Initial assessment of the brine chemistry in 2008 indicated that it had a low magnesium to lithium ratio, moderate levels of sulphate and was suitable for application of the ‘Silver Peak’ method used at the world’s first lithium brine treatment operation in Nevada, USA since the mid 1960’s. However, the ‘Silver Peak’ process, although generally applicable to the Olaroz brine chemistry, required modification to suit the differences in brine chemistry and the different climatic conditions at Olaroz. The process route also required some enhancement to produce a lithium product to meet the more demanding prevailing specifications.
The process development program sequentially defined the performance of each stage in the process, resulting in a flow sheet capable of producing battery grade lithium carbonate. Test work has been undertaken at SDJ’s facilities at Olaroz site and at commercial and university laboratories.
The process development program resulted in a process route incorporating a number of proprietary innovations. Early work focused on evaporation rate testing to understand the phase chemistry of the brine during a twelve-month weather cycle, this followed by lime addition test work to remove magnesium. Subsequently, the focus of Olaroz test work moved to the removal of boron by multi-stage solvent extraction processing, and then on to the final stage of lithium carbonate purification.
Olaroz Lithium Facility
SEC Technical Report Summary
Lithium is present at concentrations that are economic but are low in comparison to the other salts in the brine. Before final purification the other salts must be selectively rejected, and this is done primarily by evaporation, causing the salt concentrations to increase beyond their solubility limits, and by simple and well-established methods of chemical treatment. Based on test work and phase chemistry, over 70% of the lithium was modelled to be recovered in this process to a high specification product, with the majority of the lithium losses incurred by inclusion of brine in the pores of the solid salts formed during the evaporation process.
By September 2010, Allkem was producing its first pilot scale lithium carbonate and on April 8, 2011, Allkem announced that it had successfully produced battery grade specification lithium carbonate at its process development facilities from Olaroz brines. This was considered to be a prerequisite for completion of a Feasibility Study for the production of 100% battery grade material. Analysis showed the material to be of greater than 99.5% purity and to exceed specifications of battery grade material sold by existing producers.
Although the primary focus was development of the high specification lithium carbonate production flow sheet, there was a secondary focus on production of potash and boric acid. Test work showed that potash of commercial grade can be produced by froth flotation of mixed halite and potash (sylvite) salts. The deeper 2010 drilling and more detailed testing program revealed significantly higher levels of sulphate in the expanded resource than had been expected based on the shallower 2008 drilling program results. This higher sulphate level had an impact on expected potash recoveries, due to the formation of glaserite (Na2SO4.3K2SO4). The process was then expected to produce approximately 0.6 tonnes of potash per tonne of lithium carbonate or 10,000 tonnes per annum in the Feasibility Study production case.
Allkem undertook additional process development work with the aim of reducing the impact of the increased levels of sulphate and increasing potash production to the level of previous estimates, and even potentially higher levels. This work was completed well in advance of the deadline for finalizing the design and construction of the final potash circuit.
Some test work was successfully undertaken on the potential to recover boron as boric acid. Further test work and process analysis was planned on the alternative strategy of retaining the boron values in the brine through the evaporation process and recovering the boron to a commercial product.
10.2 | Metallurgical Test-Work Program |
10.2.1 | Brine Composition Analysis |
The Olaroz has a very large resource base which has the potential to support a very long life of mine. The brine composition throughout the deposit is relatively uniform, which is advantageous for process performance, as only minor brine composition changes are expected due to a small decline in grades over time.
Olaroz Lithium Facility
SEC Technical Report Summary
For all the experimental work, well FD-16B was used which was drilled during the 2008 drilling program. Analysis of the brine chemistry of the 2010 drilling data and 2011 resource estimate show FD-16B brine to be representative of the current resource.
The average brine composition is plotted in the Janecke projection (Figure 10-1), which indicates the types of salt that can be expected to crystallize during the solar evaporation process. This diagram indicates the relative concentrations of the major ionic species.
Almost all the salars are saturated in sodium chloride, since they are embedded completely in, or contacted partly with, rock salts (halite). The Olaroz Salar brine is located at the border of the Janecke glaserite (Na2SO4.3K2SO4) field and the ternadite (Na2SO4) fields. Low ambient temperatures at the salar will cause the crystallization of sulphate as glauber-salt (Na2SO4.10H20) in the evaporation ponds.
The low Mg/Li ratio of the brine makes magnesium removal with slaked lime a feasible process step. The Olaroz brine has a high sulphate content (high SO4/Mg); hence sodium and potassium sulphate salts are likely to crystallize. As it has a SO4/Mg ratio higher than 4, there is also enough sulphate available in the brine to precipitate the calcium liberated during the formation of magnesium hydroxide as gypsum. The only disadvantage of the high sulphate level is that it tends to lock up potassium as glaserite, constraining potential potash yields and at higher concentrations of lithium, causing lithium losses as lithium schoenite.
These brine chemistry characteristics shaped the path of all process testing and development.

10.2.2 | Solar Evaporation Testing |
The evaporation of water from the solar evaporation ponds is a critical factor in the processing of the brines. The feasibility study contains extensive climate data and pan evaporation testing data conducted at the Olaroz site, including comparison of data from tests conducted on water and partly saturated brine in standard Pan A equipment, and the data from concentrated brine evaporation in the pilot plant ponds. The solar radiation levels, ambient temperature, local humidity, and prevailing wind conditions all impact on evaporation rates. These factors were examined in detail in the Feasibility Study, and a summary is presented below.
The evaporation information was coherent in that the pilot scale pond testing on saturated brine provided an annual rate of 1,733 mm which is the value used in the original SKM design criteria (Table 10-1). This is conservative in the context of the Pan A test result of 3,900 mm per year on water and 2,600 mm per year on unsaturated brine.
Olaroz Lithium Facility
SEC Technical Report Summary
The actual ponds area was designed based on 1,300 mm of annual evaporation [3.6 mm/day]. This is a reasonable base line in the context of brine activity factors that range from 75 – 80% depending on saturation levels, and industrial scaling factors of 75% applied to small pond data to predict large pond evaporation rates. This also allows a generous margin to compensate for any unusually high rainfall event.
Table 10-1 – SKM Consultants Design criteria – brine evaporation rate.
SKM Design Criteria Brine Evaporation Rate | |
Pilot Pond Data | L /m² /day (mm/day) |
Annual average | 4.75 |
Summer average | 5.85 |
Winter average | 3.65 |
The most relevant and reliable information was provided by the data gathered from the large number of open evaporation test ponds operating in sequence on the salar. The weather variables needed to be defined to assist with assessing the potential for variance in the pilot plant data.
Evaporation is driven by solar radiation, ambient temperatures, wind impact and humidity, and must consider variable rainfall. The average annual temperature at Olaroz site is approximately 7° C, with extremes of 30° C and -15° C. The coldest months with temperatures below zero correspond to May through August. The solar radiation at the Olaroz Salar is almost as strong as at the Atacama Salar. Solar radiation is the most important factor in evaporation.
Rainfall at the salar is very low and during 2009-2010 no significant rain was registered at the stations. During the summer months (January – March) wind comes frequently from the east with humid air and the rain falls very locally. Summer of 2011 was very wet, and more rain and lower evaporation was registered. At the Atacama Salar and Hombre Muerto Salar normally no more than 100 mm/year is registered. Strong winds are frequent in the Puna, reaching speeds of up to 80 km/hr during warm periods of the dry season.
Figure 10-2 below summarizes the site evaporation data, comparing other sites and showing the pan test data.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 10-2 – Site Net Evaporation Rate Test Data and other sites.
The significance of the Pan A Bis data is that this was an unsaturated brine test and is compared to Pan A on just water. Pan data is the net evaporation rate, as both precipitation and evaporation are accounted for in the test pan. The rainfall in the operating years 2015 – 2021 was often significantly higher than the early design basis reflects. This contributed to reduced Li concentration in plant feed and so impacted Olaroz production .
Figure 10-3 shows how the brine evaporation rate varies compared to a standard water test as brine concentration increases [represented by Li concentration]. Brine activity is the vapor pressure ratio of brine divided by the vapor pressure of water, and it is a function of brine chemistry independent of ambient conditions. Modelling of pond performance depends on reliable brine activity data and the predictability of climatic conditions.

10.3 | Metallurgical Results |
10.3.1 | Evaporation Pond Brine Temperatures |
Temperatures in the ponds (Figure 10-4) were manually registered at 09:00 and 16:00 every day. Some ponds had continuous temperature registration using data loggers placed in the ponds.
For brine phase chemistry analysis, the lowest daily brine temperature is an important parameter as it will indicate which salt will precipitate.

10.3.2 | Phase Chemistry |
The pilot ponds operated under conditions representative of the industrial operation for over one year generating the required phase chemistry data, which defined the amount and types of salts that form as solids in the ponds through the changing ambient temperature, wind, and humidity conditions over time. Enough information was collected for the modelling of the behavior of the evaporation system for the Feasibility Study to enable definition of the brine chemistry in the feed to the lithium carbonate plant, and for detailed engineering of the pond system.
10.3.3 | Crystallized Salts |
In all the ponds it is mainly sodium chloride (NaCl > 94%) that is crystallized. Other salts that crystallize are glauber salt (Na2SO4.10H20: 2-6%) and calcium sulphate (CaSO4.2H20: 1%). In the most concentrated ponds halite and silvite (KCl) crystallize, with minor concentrations of glaserite (Na2SO4.3K2SO4) and borate salts. Under these alkaline conditions the boron is precipitated as sodium and calcium borate [Na2B4O7 and CaB4O7], and to assist in the final lithium purification process this precipitation may be encouraged by addition of calcium chloride.
The optimal lithium concentration for the recovery plant was defined by the loss of lithium at concentrations greater than ~0.7% by precipitation of lithium as schoenite [Li2SO4.K2SO4].
Olaroz Lithium Facility
SEC Technical Report Summary
10.3.4 | Liming Test Work |
Initially Allkem was using hydrated lime (Ca(OH)2) from a provider located near Jujuy for its experiments. This was replaced by active or burnt lime (CaO) from the same provider, with the advantage of reducing product and transportation costs. The active lime is of a medium grade and contains 83% active CaO. At pilot scale the lime reacted very well and completely fulfilled the process requirements. Higher quality lime from San Juan has also been tested in recent years, however the transport cost is very high, offsetting the advantages of its superior performance.
Magnesium reacts instantaneously with the slaked lime. Subsequently the liberated calcium starts to react with the available sulphate and some boron reacts early with calcium from the liberated lime. Brine at higher levels of concentration could be treated with lime, but the material handling for the concentrated brine becomes more difficult, and lithium losses increase. Data from the pilot scale trial is shown. Table 10-2 details the test work results.

10.3.5 | Boric Acid Process |
To recover the boron, its behavior in the solar ponds was studied. Several different process options were tested at lab scale to recover the boron. Some tests have been conducted which showed potential for high recovery rates, but this process is still in the preliminary development phase.
Additional testing of solvent extraction has been conducted in recent years, and preliminary tests using calcium chloride to precipitate boron have been conducted.
Olaroz Lithium Facility
SEC Technical Report Summary
10.3.6 | Potassium Chloride |
Preliminary sylvite froth flotation tests were conducted at the University of Jujuy with salts obtained from the pilot ponds. During the test the most important parameters (collector type and addition, liberation, etc) were defined to obtain an acceptable concentration of silvite salts (KCl). Future test work was planned with some additional bench flotation test followed by pilot scale testing.
10.3.7 | Lithium Carbonate Process |
The pilot plant was operated successfully from the 3rd Quarter of 2010, producing technical grade lithium carbonate.
At the beginning of 2011 the pilot plant testing process included an alternate purification step to achieve battery grade lithium carbonate. Clients were supplied with samples of this >99.5 % lithium grade product (not including moisture and LOI) for analysis.
Extensive testing was undertaken by Ekato in Europe to optimize reactor mixer design and residence time. Solids thickening and final dewatering by filtration was tested by Outotec to define equipment requirements.
10.3.8 | Analytical Quality Control |
Standardized quality control procedures were adopted and verified for analysis of the various plant streams emerging from the test work program.
These analyses are complicated since the solutions have a high concentration of ions generating interference in the measurements with the analytical equipment. Only a limited number of laboratories have the experience to analyze brines and those laboratories have been selected to do Allkem´s quality control.
The samples from Olaroz Salar were analyzed by Alex Stewart Assayers [ASA] of Mendoza, Argentina, who have extensive experience analyzing lithium bearing brines.
The Alex Stewart laboratory is accredited to ISO 9001 and operates according to Alex Stewart Group (AS) standards consistent with ISO 17025 methods at other laboratories.
Duplicate process samples were sent to:
● | University of Antofagasta (UA), Chile. |
● | ALS-Environment (ALS) laboratory located in Antofagasta, Chile, which is ISO 17025 and ISO 9001:2000 accredited. |
Olaroz Lithium Facility
SEC Technical Report Summary
Both the University and the ALS laboratory have a long history in brine analysis; however, the university is not certified.
Physical parameters, such as pH, conductivity, density, and total dissolved solids are determined directly upon brine subsamples. Determination of lithium, potassium, calcium, sodium, and magnesium is achieved by fixed dilution of filtered samples and direct aspiration into atomic absorption or inductively coupled plasma analysis systems. In summary,
● | ASA analyses show acceptable accuracy and precision with an acceptable anion-cation balance. |
● | Check samples analyzed at University of Salta display acceptable accuracy and precision, with a high degree of correlation with ASA analyses for K and Li. Mg is biased lower than corresponding analyses at ASA. |
● | Check samples analyzed at ALS Environment displayed acceptable accuracy and precision, with a high degree of correlation with ASA analyses, but the inorganic analytes (Li, K and Mg) are biased higher than corresponding analyses at ASA. |
● | Check samples analyzed at University of Antofagasta displayed acceptable accuracy and precision, with a high degree of correlation with ASA analyses, but the inorganic analytes (Li, K and Mg) are also biased higher than corresponding analyses at ASA. |
● | The lower bias observed in the ALS and UA data is most likely due to calibration differences between the ICP and AA instruments used to analyze the samples. |
The quality control systems are well designed and under continuous improvement. Data analysis of the QA results produced by the laboratories is considered to have sufficient accuracy for the purposes of process design. The improved performance of the principal laboratory, ASA, as shown by the improvement in ionic balance over time and the reproducibility of the analytical results is noteworthy and shows the benefit of a close working constructive relationship between SDJ and laboratory.
Future refined quality control with newly designed standards has the objective to improve the accuracy of certain elements for the samples related to lithium carbonate production at pilot scale.
10.4 | Recovery |
Based on past Olaroz performance, the average Li recovery for the life of mine is estimated to be 62%. Recent recoveries have been trending above this value, so it is possible that the actual recovery will be higher in the future.
10.5 | Metallurgical Performance Predictions – QP Commentary |
The test work is considered to have been undertaken on representative samples of brine and the process has subsequently been proven at the commercial production stage for approximately 8 years. It is the opinion of the applicable employee of Gunn Metallurgy (a QP) that the mineral processing and metallurgical testing data is adequate for the purposes used in the technical report summary.
Analytical testing of samples was initially conducted at the University of Salta in the very early days of the Stage 1 project, before all samples were analyzed through the Alex Stuart analytical laboratories in Argentina. Samples were principally analyzed in the Mendoza laboratory during the testing program. The Alex Stuart laboratories are ISO 9001 certified and are independent of Allkem.
Results of the test work with evaporation ponds and laboratory testing formed the basis for the process design and optimization, prior to construction of the commercial plant from around 2014.
Olaroz Lithium Facility
SEC Technical Report Summary
There are a number of deleterious elements in the brine which were discussed in the sections above. The concentration of these elements has a negative impact on brine processing. However, the concentration of these elements and an efficient way to remove them has been built into the current process.
Heavy rainfall can occur periodically on the ponds, typically in summer. The company has identified a strategy to avoid brine movement following these events, promoting the evaporation of fresh water off the top of the brine.
The applicable employee of Gunn Metallurgy set forth herein (the QP) considers that the data is adequate for the basis of the preparation of the technical report.

SEC Technical Report Summary
11. Mineral Resource Estimates
As discussed in Section 10 there have been previous reported resource estimates. These estimates are superseded by this June 30, 2023, resource estimate, which is the primary focus of this chapter.
Estimation of a brine resource require definition of:
● | The aquifer distribution (limits of the brine body). |
● | The distribution of specific yield (drainable porosity) values. |
● | The distribution of elements in the brine from drilling and sampling. |
● | The external limits (geological or property boundaries) of the resource area. |
The resource estimate uses a combination of the aquifer volume, the specific yield (portion of the aquifer volume that is filled by brine that can potentially be drained) and the concentration of elements of interest in the brine. Aquifer geometry and the extent of aquifers has been established by drilling, surface, and down hole geophysics. Drilling provides samples of sediments for porosity measurements and samples of brine for quantification of the contained content of lithium and other elements. Down hole geophysics provides continuous measurements of drainable porosity.
11.1 | Data Used for Ore Grade Estimation |
There are a number of different types of sample data available, which include:
● | Spaced down-hole assays, with the assay spacing dependent on depth of the hole. Sonic holes to 54 m deep have assays at 3 m intervals and 200 m deep diamond holes at 6 m intervals. Minimal data below 200 m. |
● | Well average assays, with a single homogenized value per hole. |
● | Laboratory porosity measurements on specific 10 cm intervals of core, at 3 m for sonic and 6 m for diamond drilling above 200 m. |
● | Continuous down-hole geophysics, with extensive information per hole, with data at cm intervals. |
This mixture of continuous and point data presents some issues when combining the two different data types. For the purposes of estimation, the well average assays were applied to the entire length of the screened intervals in production holes, while the porosity interval measurements were assigned a maximum length of six meters in the absence of adjacent samples, with BMR porosity data much more frequent.
Olaroz Lithium Facility
SEC Technical Report Summary
11.2 | Resource Estimate Methodology, Assumptions and Parameters |
11.2.1 | Resource Model Domain |
The aquifer is comprised of salar sediments with different lateral and vertical characteristics. Drilling and geophysics have provided information to develop a geological model for the salar, based on this information. This information now extends to beyond 650 m depth (with the addition of one hole to 1,400 m depth) and has greatly added to understanding of the basin since the Feasibility Study in 2011.
● | The top of the model corresponds to the phreatic surface, which is generally within one meter of surface. |
● | The outline of Olaroz properties is used to delimit the area of the resource estimate, with adjacent property owner Lithium Americas Corp in the salar to the east and north of the properties owned by Allkem and SDJ. The resource terminates at the salar boundary on the north, west and east of the salar, but extends off the salar to the south following the drilling of E26. There is limited drilling in the alluvial fans and delta environments that surround the salar. |
○ | The marginal area around the salar, including the delta area in the north, cover ~189 km2, in addition to the salar, while the Archibarca fan south of the salar covers a further ~50 km2. Part of the Archibarca area is included in the current estimate, with hole E26 the first deep hole to be drilled south of the salar in the Olaroz properties. Additional resources in the Archibarca area form part of Allkem’s Cauchari project and Exar project. |
○ | The area covered by this resource estimate (147.9 km2 in the SDJ and combined Allkem 100% properties) is larger than the 2011 Resource area (93 km2). This June 30, 2023, Upgraded Resource covers some small properties east of and outside the main body of the properties, that were not included in the 2011 resource. The Olaroz lithium properties (Allkem 100%), extend into the marginal zone (area of mixed evaporation surface crust) in the north of the salar, where resource has not been estimated, given the current lack of drilling. However, brine is likely to extend into these additional areas. The Maria Victoria property covers an additional 18 km2 on the salar, for a total of 147.9 km2 included in the resource. |
○ | The brine saturated sediments are known to extend beneath alluvial sediments surrounding the salar. However, to date insufficient drilling has been carried out around the salar and to the north of the salar (noted above) to support resource estimation there, with only part of the southern Archibarca area included in the Olaroz resources for the first time. |
○ | Within the salar the three-dimensional distributions of the different hydro stratigraphic units (UH1 to 5) were defined using Leapfrog software, with these units based on geological and geophysical logging observations. As the resource is predominantly within the salar boundary, the only location with defined resources where brackish or fresh water overlies brine within the resource area is the area south of the salar, where hole E26 is located. This relationship is also expected to be the case off the salar to the north. |
Olaroz Lithium Facility
SEC Technical Report Summary
● | The resource estimate extends to the base of the basin as Inferred Resources below 650 m depth, as defined by gravity geophysics. These Inferred Resources are defined below the 650 m depth of production wells, as the deep hole drilled in the north of the properties confirmed salar sediments continue to at least 1,400 m depth in this deepest part of the basin and drill holes in the southwest of the salar show the basin depth is underestimated. |
○ | As Olaroz is pumping from production wells to 650 m depth, in similar sediments to those extending below / interpreted to extend below 650 m, Hydrominex Geoscience (the QP) considers there is sufficient confidence in pumping extraction from this geological environment to classify the deep area of the basin (>650 m) as Inferred Resources, rather than an exploration target. |
○ | Extraction below 650 m is not planned as part of Stage 2. However, it is likely the resource classification of this deeper brine could be improved with additional drilling. |
The resource is defined within the salar boundary, except for the area around hole E26 south of the salar. This is the only area in the updated resource where fresh to brackish water is overlying brine in the resource.
It is noted in hole E14 in the center south of the resource area extends through the interpreted base of the salar, based on the gravity geophysics survey. That the modelled base of the salar is conservative, and extends blow the current interpretation, is confirmed by holes E22, E24 and E26 (Figure 11-1) which all extend through the interpreted basement contact.
Shuttle Radar Topography Mission (SRTM) topography data was used to produce a wireframe of surface topography. Wireframe models developed based on drilling and representing the lithological units were used for the resource estimation. The lithological wireframes define the base of the salar and internal units. For estimation purposes, the salar sediments were divided into two broad domains: Domain 1 is the flat upper part of the salar, while Domain 2 is the lower dipping part of the sequence, where units become progressively deeper to the east. Figure 11-2 shows a cross-section of the various lithological unit wireframes; Domain 1 includes units 1, 2 and 3, while Domain 2 comprises units 4 and 5.

The resource estimate was undertaken by H&S Consulting of Sydney, Australia, under supervision of the employee of Hydrominex Geoscience set forth herein (the QP). Micromine software with variograms was developed for the point samples from the upper 200 m. Estimation was undertaken using ordinary kriging. The ordinary kriging method is the most commonly used kriging method.

SEC Technical Report Summary
The block model was constructed with 500 by 500 by 20 m blocks, with the proportion of blocks only reported inside of the resource area (salar outline) and any portion of the block outside the salar outline excluded:
● | Histograms, probability plots and box plots were undertaken as part of the data analysis. |
● | Variograms were developed for the three orthogonal directions. |
● | Kriging criteria were defined. |
● | The resource was estimated using information from the brine and porosity models. |
Details of the model are summarized in the Table 11-1.

11.3.2 | Specific Yield |
Specific yield (drainable porosity) is the key porosity variable that reflects the brine held in pores in the aquifer which can potentially be extracted. This measurement can be made in a number of ways, consisting of both laboratory and in-situ determinations. In Olaroz (and the neighboring Exar Project owned by Allkem) a total of 765 laboratory measurements of specific yield have been made. This information is primarily available from laboratory sample results in the upper 200 m at Olaroz, where diamond and sonic drilling was conducted. At Cauchari laboratory data is available to depths approaching 600 m, although that was not used in the estimation specific yield values for different lithologies were compared with BMR results used in the estimate.
At Olaroz below 200 m there are limited laboratory measurements, restricted to the eastern property boundary. However, production wells for the expansion were geophysically logged with a borehole magnetic resonance tool (as discussed in the drilling section above). This provides continuous measurements of drainable porosity, showing how this varies on a scale of meters and less. The BMR information has been used for the estimation to supplement the limited laboratory porosity data available below 200 m. The porosity data from the BMR geophysics was used to generate a block model across the salar area applying ordinary kriging to smoothed BMR drainable porosity data. The BMR tool was developed in the oil industry for measurement of drainable porosity and is a well-established tool, considered to be much better suited for use in salars than the equipment previously used.
Olaroz Lithium Facility
SEC Technical Report Summary
Geophysical logging in the deeper holes has confirmed generally consistent drainable porosity and permeability characteristics throughout the clastic sediments, with higher porosities and permeabilities associated where thicker more sand dominated intervals of unit UH5.
11.3.3 | Brine Concentration |
The distribution of lithium and other elements was estimated from point sampling data from the upper 200 m of the model, where samples are typically spaced every 6 m in the 200 m holes and 3 m or less in the 54 m holes. Below the upper 200 m the resource was estimated based on the pumped samples from the production wells, with a single value per hole representing the average pumped value for each hole, applied over the intervals where filters are installed. There is a systematic variation across the salar, and this broadly reflects the pattern presented in the 200 m deep resource drilling results from 2011.
The employee of Hydrominex Geoscience set forth herein (the QP) considers use of the pumped brine samples an acceptable approach, given the level of information available in the Olaroz Salar, continuity between drill holes, comparison between historical interval samples and pumped brine concentrations from the same areas of the salar, and the 8 plus year history of pumping data available.
11.3.4 | Search Parameters & Block Model Interpolation |
Data analysis of lithium (Li) concentrations involved statistical analysis using histograms, probability plots, contact plots and box plots, and a spatial description using trend analysis. Analysis showed that some variables show significant differences between hydro-stratigraphic units, whereas others show little difference. Data analysis was more limited for the deeper units where brine samples are from the pumped wells and porosity data is derived from the BMR geophysics. Gamma ray data were used as a check on the definition of the hydro-stratigraphic units which are considered reasonable, based on the available geological and geophysical data. Gamma ray data provides information that allows relative assessment of the halite, clay, and sand content.
Ordinary kriging is the most commonly used kriging estimation method. Ordinary kriging re-estimates, at each estimation location, the mean value by only using the data within the search neighborhood.
● | A four-pass search strategy was implemented, as outlined in Table 11-2. The first two passes have narrow vertical (Z) radii to reflect the bedded nature of the salar sediments. The second two passes have much larger vertical radii because of the limited amount of data at depth and the need to maintain the lateral trends observed near surface. This was modified in this latest 2023 estimate, which considered public porosity and brine concentration data from the third party Solaroz project, adjacent to Allkem properties north off the salar. |
● | The BMR geophysical data for specific yield was not used for the estimates of the upper 200 m of the deposit, where the historical and spatial more distributed laboratory porosity data is available. |
Olaroz Lithium Facility
SEC Technical Report Summary
● | There is a soft boundary between Domains 1 and 2 for brine grades, and a hard boundary between Domains 1 and 2 for specific yield. |
● | The salar boundaries were defined with a block fraction at 50 x 50 m resolution. |
● | The model was validated in several ways – visual and statistical comparison of block and drill hole grades and examination of grade-tonnage data. |
● | Visual comparison of block and drill hole grades showed reasonable agreement in all areas examined and no obvious evidence of excessive smearing of higher-grade brine assays. However, some changes were made between March and June 2023 estimates. |
● | A comparison of average sample and block grades is presented in Table 11-3 shows that block grades inside the salar boundary are broadly comparable to the samples and differences can be explained in terms of the clustering of drill hole samples in the center of the salar. |

11.3.5 | Block Model Statistical Validation |
All sample data was composited to nominal 2.0 m intervals for analysis and estimation, and determination of summary statistics. Data includes four elements (Li, K, B, Mg) in concentrations of milligrams per liter (mg/l), as well as total porosity specific yield (SpecYld) as percentages and gamma in API units. All attributes have low coefficients of variation (CV=SD/mean), which indicates that ordinary kriging is an appropriate estimation method for these items.
Variograms were generated for these attributes, with some examples presented in Figure 11-3 and variogram parameters provided in Table 11-6. The assays were assumed to be horizontal across the entire salar, while porosity and gamma were divided into the upper and lower domains for both Variography and estimation. The lower domain has a shallow dip to the east. Contact plots of different lithologies are shown in Figure 11-4 and Figure 11-5.
The grade tonnage curve shows essentially no difference in resource tonnage with a cut-off between zero and almost 400 mg/l, due to the large and fairly homogeneous character of the resource. The Resource is stated at a 300 mg/l lithium cut-off, as a result of Allkem’s global review of Resources. The Resource is mostly restricted to the salar boundary, except for a small extension south off the salar. Exploration indicates the brine body extends significant distances away from the salar, for example in drilling by Allkem subsidiary South American Salars south of the Olaroz plant and ponds.
Olaroz Lithium Facility
SEC Technical Report Summary
The resource around hole E26, south off the salar, lies beneath alluvial gravels and brine does not begin near surface, but is overlain by brackish water, beneath dry sediments from surface. The resource here is trimmed to the brine surface and does not include brackish water overlying the lithium-bearing brine. This is similar to the areas drilled in the west of Cauchari by South American Salars (formerly Advantage Lithium – Allkem 100%).

11.4 | Mineral Resource Classification |
The resource was estimated using 4 passes with the search strategy (Table 11-2). The results of the first two passes are nominally equated to blocks classified as Measured and Indicated, with the latter two passes equating to blocks classified as Inferred.
Figure 11-6 – Olaroz grade tonnage curve – all of the salar.
11.4.1 | Measured Mineral Resources |
A ‘Measured Mineral Resource’ is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.
Geological evidence is derived from detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes, and is sufficient to confirm geological and grade (or quality) continuity between points of observation where data and samples are gathered.
Olaroz Lithium Facility
SEC Technical Report Summary
A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Reserve category or under certain circumstances to a Probable Reserve category.
The Measured classification is based on reliable geological correlation between drill holes, which show gradual changes in lithology laterally and with depth. Measured Resources were defined to cover the entire salar area to 200 m depth, as exploration drilling was previously conducted across the salar area to 54 m and 200 m depth. The deeper extension of the Measured Resource is defined based on the drill hole depth, with the resource to 650 m depth in the east of the salar and 450 m deep in the west, where drill holes are shallower. Measured Resources are defined to 350 m depth around holes drilled in the Maria Victoria property, in the north of Olaroz, extending below the 200 m depth defined elsewhere in the north of the salar.
Classification is supported by ongoing extraction by pumping of brine from production wells installed to 200 m for a period in excess of eight years the central area of the resource, with 1 km spaced production wells and a drilling density of approximately 1 hole per 2 km2. Since 2013 production wells to 200 m depth have been installed and operated from depths of 200 m, with wells deeper than 300 m producing from 2014 onward. The original exploration included exploration holes and a pumping well (PD01) in the far north of the area on the salar and another (PD02) in the south of the salar.
An additional area of Measured Resources has been defined around the three diamond drill holes on the easter margin of Olaroz, south of the deep hole E1. An extension of 2.5 km from the property boundary has been applied for definition of this measured resource, consistent with the suggestion of Houston et. al., 2011. This is considered a reasonable basis for extension of the resource to 650 m depth in this area, surrounded by Indicated Resources.
The Measured Resources are almost all within 2.5 km from drill holes across the salar, as suggested by Houston et. al., 2011 as an appropriate drilling spacing for Measured Resources in clastic salars. The drilling spacing of wells and exploration holes is greater than 1 km outside the existing Stage 1 and new Stage 2 wellfields, however geological continuity supports classification as a Measured resource within this 2.5 km radius of drill holes.
11.4.2 | Indicated Mineral Resources |
An ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes, and is sufficient to assume geological and grade (or quality) continuity between points of observation where data and samples are gathered.
Olaroz Lithium Facility
SEC Technical Report Summary
An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Reserve category.
Geological continuity established by deeper drilling below 200 m, geophysical logging of holes, and gradual changes in lithium concentration provide the basis for classifying the brine beneath the Measured Resource to 650 m depth as Indicated. From 200 to 350 m below surface in the north of the salar (with lesser drilling density), outside the 2.5 km influence of drilling in the Maria Victoria property, and south off the salar around hole E26 are also classified as Indicated.
Laboratory porosity samples are relatively limited below 200 m, however similar sediment intervals are present above 200 m at Olaroz, where porosity characteristics have been established from hundreds of laboratory analyses. Extensive porosity samples from similar sediments are also available from the Allkem Cauchari properties. Ongoing extraction by pumping of brine from wells up to 450 m deep since 2014 and from 650 m depth for approximately 3 years, provides confidence as to the extractability of brine from the resource to this depth.
Additionally, BMR geophysical porosity data has been collected below 200 m depth in holes to 650 m deep. Future drilling below 200 m provides the opportunity to upgrade Indicated Resources to Measured status.
11.4.3 | Inferred Mineral Resources |
An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes.
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and may not be converted to a Reserve category. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
The Inferred Mineral Resource is defined between 350 m and 650 in the north of the salar where there is less drilling. Within the salar Inferred Resources are defined below 650 m and the base of the basin. The base of the basin is defined by the gravity geophysical survey, with areas significantly deeper than 650 m defined. There are currently 18 production wells installed below 350 m, with production wells for the Olaroz Stage 2 installed between 400 and 650 m deep (E15 to 751 m) between the existing northern and southern wellfields. The deep hole drilled in the north of the salar confirms locally the salar sediments extend to below 1,400 m depth. Drilling has not intersected the base of the salar sediments, where the geophysical estimated basement depth has been reached, suggesting the basin may be deeper than estimated from the gravity survey.
Olaroz Lithium Facility
SEC Technical Report Summary
Taking account of the distribution of brine grade and porosity to date (as determined by BMR geophysics) there is a sufficient level of confidence to classify the Resources extending to the bottom of the basin as Inferred Resources. It is likely that additional drilling could convert these to a higher confidence resource classification. It is noted that different geological units may be discovered in the deeper part of the basin, where there is very limited drilling to date.
11.5 | Olaroz Mineral Resource Estimates |
The resource estimate is outlined in the following tables presenting the lithium and lithium carbonate tonnages. The resource is broken out by property ownership with the bulk of the resource within the Allkem Sales de Jujuy joint venture. Allkem holds additional 100% owned properties, through Olaroz Lithium and La Frontera Minerals, in the north of Olaroz. In the SDJ and Olaroz Lithium properties to the North and south of the Olaroz salar, outside the salar boundary, there are likely to be significant additional volumes of brine that have not yet been explored and quantified.
The Resources are reported at a 300 mg/l lithium cut-off as the entire Olaroz Salar contains brine with an elevated lithium concentration, which based on drilling to date is above the likely minimum concentration for processing of brine. Block model grade and porosity data is shown in Figure 11-7, Figure 11-8, and Figure 11-9. Figure 11-10 to Figure 11-13 show the block model with different characteristics.
The Resource estimate is outlined below, showing the lithium and lithium carbonate tonnages. The resource is presented by resource classification, with 22.6 Mt of Resources within the Olaroz properties, almost all on the salar. Allkem holds additional 100% owned properties, through Olaroz Lithium and La Frontera Minerals, in the north of Olaroz. The SDJ properties contain 13.1 Mt LCE of Measured and Indicated Resources and 4.1 Mt of Inferred Resources. The Olaroz Lithium and La Frontera properties (100% Allkem) contains 2.3 Mt of Measured and Indicated Resources and 3.2 Mt of Inferred Resources.

In the SDJ and Olaroz Lithium properties to the North and south of the Olaroz Salar, outside the salar boundary, there are likely to be significant additional volumes of brine that have not yet been explored and quantified.
This June 30, 2023, Resource update is the first reporting of Olaroz resources in the S-K 1300 format and is an update, superseding the JORC Compliant resource announced on March 27, 2023, and earlier resource estimates in 2022 and 2011.
This June 30, 2023, Resource does not discount production to date from within the resource. Approximately 291,292 tonnes of lithium carbonate equivalent have been extracted by pumping between 2013 and June 30, 2023. This is equivalent to approximately 54,724 tonnes of lithium metal.
Table 11-7 presents the Mineral Resources exclusive of historical production. When calculating Mineral Resources exclusive of historical production, a direct correlation was assumed between Measured Resources and Proven Reserves as well as Indicated Resources and Probable Reserves. Reserves at a point of reference of the wellhead, before applying the process recovery factor, were subtracted from the Resources inclusive of Reserves. And it was assumed historical production between wells located in the volume of Measured Resources are excluded in this resource and wells located in the volume of Indicated Resources are excluded in the Indicated Resource.

There are a number of differences between the June 30, 2023, and March 27, 2023, resource estimates. These include:
● | Use of a 300 mg/l external cut-off, versus a zero cut-off in the March 27 version. |
● | Incorporation of public specific yield porosity and lithium concentration data from the adjoining Solaroz third party properties, which confirms the northern extension of the Olaroz geological model. This information indicates higher specific yield and lithium concentrations are likely in the north of the salar and north of the salar, compared with those previously modelled by Allkem. |
● | Modifications to the search radius and orientation, making lithium concentrations more laterally continuous than in previous models. This has resulted in greater horizontal continuity within the model. |
● | Revision to the area around E26, where the upper 100 m (hosting brackish water) was previously removed from the model. |
● | Increased specific yield in the north of the model has resulted in an overall increase in tonnage, mostly in the Inferred category. |
● | The resources have been depleted for the historical production from 2013 to 2023. |
Olaroz Lithium Facility
SEC Technical Report Summary
11.6 | Potential Risks in Developing the Mineral Resource |
Some general risk factors are associated with Olaroz. These risks include, but are not limited to:
● | Properties: The risk that properties might not be fully granted or maintained, due to administrative errors or failure to make the annual property payments. |
● | Assays: The risk that assay results are not representative of the fluid present in sediments within the properties, due to the relatively small number of samples taken during deeper drilling, despite consistent results between drill holes. |
● | Geophysics: Interpretation of the base of the salar is heavily reliant on gravity geophysics, for which multiple interpretations of the data are possible. Definition of the limits of the Olaroz brine body depends on the AMT and VES geophysics. Consequently, there is a risk that the actual geology and thickness of the sediments is different to that interpreted from the geophysical data. |
● | Fluid sampling: Brine sampling during diamond drilling entails risks of contamination from drilling fluid. Although results from pumping tests on rotary drill holes installed as production wells suggest this is not the case, depth specific brine samples from diamond holes can potentially be contaminated by drilling fluid. |
More generally there are risks that:
● | Necessary license and permits will not be received from the necessary authorities in a timely manner on acceptable terms or at all. |
● | Changes in federal or provincial laws and their implementation, impacting activities on the properties. |
● | Unseasonal rainfall could occur, which could temporarily delay planned exploration. |
● | Future changes in lithium price, which could affect the economics of lithium production in the event that sufficient lithium was defined in Olaroz area that could potentially be produced economically. |
● | Economic and political conditions in Argentina could change, such that the country risk profile is different to that which is currently assessed by relevant experts. |
● | Covid or other pandemics result in delays and changes to activities, due to government requirements, impacts from government requirements, unavailability of people and equipment or sickness. |
11.6.1 | Discussion of Cut-Off Grade |
A lithium cut-off grade of 300 mg/l was conservatively utilized based on a cut-off grade for a projected lithium carbonate equivalent price of US$20,000 per tonne over the entirety of the LOM. Considering the economic value of the brine against production costs, the employee of Hydrominex Geoscience set forth herein (the QP) considers the economic assumptions appropriate for the 300 mg/l cut-off grade assignment to account for potential uncertainties in the projected price and processing considerations (see Chapter 10).
Olaroz Lithium Facility
SEC Technical Report Summary
Furthermore, the assigned 300 mg/L cut-off grade is consistent with other lithium brine projects of the same study level, which use a similar processing method.
The cut-off grade is based on the various inputs and formula below:
The cut-off grade was elevated to 300 mg/l to increase margin and de-risk the uncertainties around price fluctuations. The cut-off grade is used to determine whether the brine pumped will generate a profit after paying for costs across the value chain.
The resource is relatively homogeneous in grade (as shown in the grade-tonnage curve of Figure 11-6), and the average concentration is well above the cost of production, with brine concentrated in low-cost solar evaporation ponds. It is uncertain whether direct extraction technology will be used to extract brine in the Olaroz Stage 3 development. When this is defined, the cut-off grade will be re-evaluated.
Almost all the mineralization hosted in the mineral resource is within the salar. It does not underline areas of brackish water that could eventually affect extraction, except the area around the southern hole E26 near the evaporation ponds.
The price estimate for Lithium Carbonate is based on information provided by industry consultants Wood Mackenzie, based on their extensive studies of the lithium market. Actual prices are negotiated by Allkem with customers, generally as contracts related to market prices.
The employee of Hydrominex Geoscience set forth herein (the QP) understands the lithium market will likely have a shortfall of supply in the coming few years, which will support higher than inflation-adjusted historical prices. Based on 2022 and 2023 pricing to date, the Wood Mackenzie analysis is considered a reasonable basis for pricing through to 2025. By this time, a new technical report will likely be completed, outlining operations and details for the Stage 3 project.
11.6.2 | Uncertainty analysis |
All resource estimates are subject to uncertainty. In the case of lithium brine deposits, the deposits are similar to bulk mineral deposits, with premium pricing for the lithium product. There is uncertainty related to sampling, drilling methods, chemical analyses, data processing and handling, geologic modelling, and estimation. Data processing and handling, geological modelling and estimation have been the same for all data. Geochemical analyses are considered to have been sufficiently similar throughout the exploration activities at Olaroz.
As the lithium concentration changes gradually within the salar the major source of uncertainty in resource estimation on the salar is related to the specific yield (porosity which can be extracted). The specific yield changes on a cm level in clastic sediments (sediments that range from clay to gravel) and is generally less variable in halite and evaporite sediments below 50 m. Therefore, controlling variability in specific yield is the key means of reducing uncertainty.
In order to reduce uncertainty in specific yield down hole geophysical logging was undertaken with a borehole magnetic resonance (BMR) tool. This information provided data on specific yield every 2 cm down hole, supplemented by laboratory testing of cores for comparison. The specific yield data from the BMR logging data was estimated across the salar area for the resource estimate.
Olaroz Lithium Facility
SEC Technical Report Summary
The resource estimate was checked against the original assay data in holes with interval sampling and pumped brine wells. Visual and statistical comparison of block and drill hole grades and examination of grade-tonnage data were evaluated to assess the estimation and the level of uncertainty.
The degree of uncertainty is reflected in the drilling density, length of production from the area and the resource classification. The Measured Resources are defined to a depth of up to 650 m across the salar and have been subject to brine extraction since 2013 from the upper 200 m of the salar. This area was subject to sonic (54 m) and diamond drilling (200 m) prior to commencing production. Additional diamond drilling was conducted to 650 m along the Eastern property boundary, to provide extra information about lithology and continuity. These areas included discrete interval sampling of brine and porosity sampling. Indicated Resources are defined below the base of Measured Resources beneath 200 to 650 m along the western side of the salar, where they occur more than 2.5 km from or beneath expansion E-series production holes. Indicated Resources are also defined within 2.5 km of the hole E26, south of the salar. Inferred Resources were defined in the northern and (to a lesser extent) southern ends of the salar, where there is little drilling and consequently greater uncertainty. This will be addressed with future drilling, to improve confidence in these areas. Inferred Resources are also defined below 650 m, where information is provided by the deep drill hole E01.
Overall, the uncertainty in the estimate has been addressed with the resource classification and checking of the estimate versus the original data.
11.6.3 | Risks and Reasonable Prospects for Eventual Economic Extraction |
There is considered to be minimal risk to developing the Mineral Resources, as Olaroz is already in production, having extracted brine since 2013 and sold lithium product from 2015. Lithium has been extracted from depths covering most of the Mineral Resources (down to 650 m) and deeper development would be possible.
There are ‘reasonable prospects for eventual economic extraction’ as extraction activities over a period of approximately 10 years from the central and southern areas of the salar have resulted in a successful brine extraction operation, with continued lithium processing, production, and sales of lithium carbonate product.
Given that brine has been extracted from the deeper UH5 unit of the basin since the initial holes drilled in 2014, the employee of Hydrominex Geoscience set forth herein (the QP) considers there are reasonable prospects for economic extraction of brine from the depths where production holes are currently installed to 650 m.

Olaroz Lithium Facility
SEC Technical Report Summary
13. Mining Methods
This section describes the wellfields used for brine extraction and the mobile equipment used to support site operations. The numerical modeling used to support mine designs, simulate production rates, and predict mining dilution is discussed in Chapter 12. Chapter 14 outlines the process operations including the booster ponds, evaporation ponds, and the process plant.
13.1 | Brine Extraction |
Lithium bearing brine hosted in pore spaces within sediments in the salar will be extracted by pumping using a series of production wells to pump brine to evaporation ponds for concentration of the brine. Extraction of brine does not require open pit or underground mining and is the only feasible method to extract brine. Extraction is comparable with groundwater extraction for other uses (I.e., agriculture, although the brine is not suitable for agricultural use). Olaroz currently produces brine from two wellfields with wells installed to 200 m depth, with several other production wells installed to 350 and 450 m deep.
Installation of wells for the Stage 2 expansion of Olaroz has now been completed, with a total of 15 production wells installed between depths of 450 and 650 meters, depending on the location in the salar. The expansion wells fill in the space between the existing northern and southern wellfields in the center of the salar. Wells consist of stainless-steel screen sections and carbon steel casing sections, designed based on geological and geophysical logging to maximize inflow into the wells. Pumps are individually selected for each well, depending on the performance of the well during the variable rate (step) and constant rate tests.
Pipelines for individual wells transport the brine to transfer ponds, from where brine is pumped by high flow pumps through larger pipelines to the evaporation ponds. Overhead electrical power is supplied to each well site to power the submersible pump and controller. The wells are located on elevated platforms, that are connected by elevated roads to the edge of the salar, offices, workshops, and other infrastructure. This ensures that wells operate even when periodic seasonal flooding of the salar takes place in some wet seasons. The evaporation ponds for the Olaroz Stage 2 expansion are located directly south of the plant and stage 1 ponds on the lower slopes of the Archibarca alluvial fan. The distribution of the E series and PP series operational wells and other drill holes is shown in Figure 13-1.
Olaroz Lithium Facility
SEC Technical Report Summary
Figure 13-1 – Actual expansion production wells in brown, Stage I production wells in yellow.
Olaroz Lithium Facility
SEC Technical Report Summary
Wells are operated 24 hours a day, throughout the year, using submersible pumps with scheduled maintenance periods for wells, allowing wells to be taken out of service periodically for cleaning. The pumping regime for wells is seasonal, with greater pumping during the warmer months of the year, which have higher evaporation and lower pumping rates during the low evaporation winter months. Wells are producing at an average flow rate of greater 28 liters/second, with pumping tests conducted at up to 60 l/s in some wells to date.
Additional details regarding project infrastructure are provided in Chapter 15 Infrastructure.
13.1.1 | Production Rates, Expected Mine Life, Dilution and Recovery |
The production rates vary between wells, as each well has a different hydrogeology at a detailed scale. The combined production rate for Stages 1 and 2 is in the order of 650 l/s. The brine extraction plan has been developed for Olaroz with a mine life of 40 years (30 years excluding the 10 years of actual production since 2013). As extraction is by pumping there are no mining unit dimensions, unlike hard rock mining. However, holes are generally separated by 1 km and in general the influence of brine extraction will extend beyond that distance from wells over the mine life, within the 147.9 km2 area of the resource estimate. The reserve estimate includes a simulation of brine dilution over time, which is considered to manifest as a gradual decline in lithium concentration over time, which is less than 10% of the starting concentration. Brine mining does not involve mining units such as in open pit or stoping operations. Each well can be considered a mining unit, with a spacing of 1 km between wells. The recovery factor is influenced by the pre-processing concentration and the recovery in the different stages in the plant. The lithium recovery factor has varied over time but averages approximately 60%.
The annual numerical values and totals for the Life of Mine (LOM) production, including the quantities pumped from the wellfields with associated solution grades, the overall recovery, and final salable product are detailed in the Table 13-1.
Table 13-1 – Annual numerical values and totals of Life of Mine (LOM) production
Note: The overall recovery is calculated considering the total lithium units produced relative to the total lithium units pumped out of the wells. It may be affected by the pond inventory and production ramp-up, causing temporary fluctuations. At stable production levels, the overall recovery is approximately 62%.
13.2 | Hydrological Considerations |
Salars form in arid environments, with the deposition of chemical sediments, with deposition controlled by the concentration of elements in brine and saturation of brine with respect to different minerals which precipitate progressively. Salars typically have an inner nucleus of halite, that is surrounded by marginal zones on the sides of the salar where sulphates and carbonates are deposited.
Fine grained clastic sediments such as clays and muds are typically deposited in Salars, some of which may contain organic material from decomposed vegetation. Coarser grained sediments generally occur on the margins of basins and may prograde into the basins from the sides during wetter periods when coarse sediments were transported further.
Olaroz Lithium Facility
SEC Technical Report Summary
Drilling at Olaroz has defined the five major hydrogeological units that are discussed in section seven. The general geological environments at Olaroz that relate to the hydrogeological units are as follows:
13.2.1 | Alluvial Fans |
These are best developed on the western margin of the Olaroz salar, with the largest being the Archibarca alluvial fan, a composite fan developed from the southeast of the Olaroz basin. This consists of coarse gravel, generally with a sandy matrix, with interbeds of more clayey material between thicker and more massive gravel units. The Archibarca fan prograde into the Olaroz and Cauchari salars and forms the boundary between the two Salars. The alluvial fan receives significant recharge from seasonal rain and snowmelt and hosts a resource of fresh water that is used for Olaroz water supply. The freshwater overlies brackish water and brine below the gravels.
Drilling shows that historically the Archibarca alluvial fan deposited sediment into the basin from west to east. Coarser sediment from this source was deposited in unit UH5, which can be correlated across the salar, and which supports the highest pumping rates to date in wells such as P302 and E17. In many salars a lower unit with more sand and gravel clastic material is observed, which is likely to reflect different climatic conditions in the Puna region at that time and coarser sedimentation deposited in the earlier stage of basin development.
13.2.2 | Clay and Silt |
Clay and silt units form much of units UH3 and UH4, with interbedded sand units. These units cover the central part of the salar and are interbedded with coarser sediments from alluvial fans along the western margin of the salar. These units act as thick leaky aquifers, which release brine continuously, but at lower rates than units with thicker sequences of sand and gravel.
13.2.3 | Halite |
Halite is typically deposited in salar basins and in Olaroz is developed most consistently in unit UH4, where it forms a thick sequence that is interbedded with clay and silt. The halite (salt) unit is distinct in geophysical logs, as the unit is generally compact and less permeable. However, interbedded coarser grained clastic layers can have higher permeabilities and better production, such as in the southern wellfield.
13.2.4 | Drainable Porosity (Specific Yield) |
Porosity is highly dependent on the host lithology, with different types of porosity related to the size of pores and how brine (fluid) can be extracted from the pores.
Olaroz Lithium Facility
SEC Technical Report Summary
It is important to understand the terminology relating to porosity (Figure 13-2). Total porosity (Pt) relates to the volume of pores contained within a unit volume of aquifer material. Except in well-sorted sands some of the pores are isolated from each other and only the pores that are in mutual contact may be drained. This interconnected porosity is known as the effective porosity (Pe). Assuming the Pe is totally saturated, only part may be drained under gravity during the pumping process. This part of the porosity is known as the specific yield (Sy or the drainable porosity). A portion of the fluid in the pores is retained as a result of adsorption and capillary forces and is known as specific retention (Sr).
Figure 13-2 – Relationship between total porosity, specific yield, and specific retention for different grain sizes.
Total porosity (Pt) is much higher in finer grained sediments, whereas the reverse is true for Sy, due to the high Sr in these sediments. Lithology is highly variable, with sand-silt-clay mixes spanning the full spectrum of possible porosities. It is only possible to discriminate between the dominant lithology, for example, sand dominant or clay dominant. Consequently, the porosity of sand dominant, or clay dominant lithologies have a wide range with considerable overlap (Table 13-2).
Specific yield analysis was carried out on undisturbed core samples from the partially completed diamond drilling program at Olaroz. Primary samples were analyzed by the Geosystems Analysis laboratory in Tucson, USA. Check samples were analyzed at the DB Stephens laboratory, in Albuquerque, USA.
Olaroz Lithium Facility
SEC Technical Report Summary
Extensive historical porosity data is also available from porosity sample testing at Olaroz in 2010-11 and from test work conducted at the Cauchari project between 2011 and 2018 in equivalent sediments.
Results of the specific yield (drainable porosity) analysis are summarized in Table 13-2, with results from recent and historical sample analyses.

Clay Dominant | 0.03 ±0.02 | |
Halite Dominant | 0.04 ±0.03 |
13.2.5 | Permeability Testing |
Permeability (hydraulic conductivity) is also highly dependent on lithology. Generally finer grained sediments such as clays have lower permeability than coarser grained sediments such as sands and gravels. Near surface halite is often highly permeable, due to a network of fractures, although halite becomes progressively more compact and less permeable with depth. However, cavities and fracture networks are observed in some deeper halite units. The sequence of sediments in the Olaroz Salar exceeds 650 m thickness. Extraction from below 50 m is from semi-confined to confined aquifers.
Permeability for extraction purposes is best measured by conducting pumping tests and evaluating changes in the water level in the pumped well and observation wells. Pumping tests were carried out on wells installed for the expansion program, with variable rates and constant rate pumping tests conducted over periods of up to 48 hours. The results of the pumping tests are summarized in Table 13-3 and Figure 13-3 below.
From the available information the heterogeneity of the mixed clay and sand unit in Olaroz is clear. The highest hydraulic conductivity (K) values are generally related to unconsolidated deposits, in particular the Archibarca alluvial fan. Pumping test results show values of between 3.4 and 67 m/d in this material.
Olaroz Lithium Facility
SEC Technical Report Summary
The unconsolidated deposits have a range of storage coefficient in the order of 4x10-4 to 2x10-1 related to unconfined to semiconfined parts of the aquifers. The deeper semi-confined to confined units composed of clays, silts and sands have values in the order of 1x10-3 to 3x10-6. Permeability values defined for the hydro stratigraphic units are shown in Table 13-3.
The pumping undertaken at Olaroz for brine production constitutes a long-term pumping test that has been monitored throughout the salar and provides extensive information for understanding the response of the aquifers in response to pumping.

Unit | Hydraulic Conductivity Range m/d | Storage Coefficient Range |
UH1 | 0.15 - 2.5 | 10 - 15% |

14. Processing And Recovery Methods
This section discusses the processing of lithium containing through the carbonation process to produce salable products. It further discusses required process input and services.
14.1 | Process Design Criteria |
The process design is based on the test work discussed in Chapter 10, and the numerical modelling in Chapter 12. The selected process for Olaroz II is shown in Figure 14-1. The process is based on the Olaroz I process plant that has been in operation since 2015
The process plant will operate year-round, with a planned plant availability of 8,000 hours per year. The surge capacity of the buffer ponds will allow the plant throughput to remain constant, while the evaporation rate and pond throughput will seasonally vary.

Olaroz Lithium Facility
SEC Technical Report Summary
14.2 | Process Flow Description – Stage 2 Expansion |
The Olaroz process relies upon:
1. | Removal of the bulk of the magnesium content by slaked lime addition to the brine. |
2. | Increasing the Li concentration by evaporation, removing many different salts along the evaporation path by crystallization. |
3. | Polishing of the upgraded brine by removal of calcium and magnesium at an intermediate temperature and carbonate concentration. |
4. | Precipitation of the lithium carbonate product using high temperature and high carbonate additions. |
14.2.1 | Wellfields |
Each of the northern and southern wellfields distributed over the properties on the salar delivers brine from 200 m or >200m depth into intermediate tanks, which are constructed as deep, compact plastic lined ponds. The brine is pumped from the north and south tanks [with several wells close to the pond area pumping directly] to the liming plant reactors. The total flow for Stage 1 is ~240 l/s at a grade ranging from 650 – 700 mg/l Li.
The brine wells drilled for the expansion are deeper and better equipped than Stage 1, using a more advanced geophysical profiling strategy and screening technology to optimize flow. They are generally located between the existing northern and southern wellfields. It is anticipated that with the planned 15 new wells a total flow for Stages 1 and 2 of up to 654 L/sec can be sustained at a minimum Li concentration of 650 mg/L. This has been supported by testing of some of the new wells as they became available since early 2020.
14.2.2 | Lime Addition |
The objective of liming is to remove magnesium from the brine. Brine will be treated with milk-of-lime, a hydrated (slaked) lime slurry as Ca(OH)2, to precipitate magnesium as Mg(OH)2. Other solids produced will include borate solids and gypsum (CaSO4•2H2O).
Burnt lime [CaO] is delivered to the Olaroz site by tanker truck which pneumatically discharges burnt lime into silos. The burnt lime is slaked with raw water in a small grinding circuit and the slaked lime stored in an ageing tank. From the ageing tank the slurry is added to the brine in twin reactors in series where magnesium hydroxide and calcium sulphate are rapidly precipitated. Control of calcium [Ca] and magnesium [Mg] concentrations in the brine is critical to the recovery of a quality lithium product as they will co-precipitate.
The precipitates are contained within the first evaporation pond for later reclamation and disposal.

14.2.3 | Evaporation Ponds – Stage 2Expansion |
The Stage 2 expansion has been designed primarily based on the experience gained from 5 years of operating, development, and data analysis from the Stage 1 ponds. Some equipment specific testing was also conducted, mostly the new solid liquid separation steps in the polishing area.

Refer to Figure 14-2. The pond design for stage 2 [pond numbers 15 and up shown below] uses flat bottoms to enable salt harvesting and improved control. These ponds are dimensioned to have overall a greater area ratio to brine feed flow than the stage 1 design.

Olaroz Lithium Facility
SEC Technical Report Summary
The Olaroz II plant is similar in its general process flowsheet and chemistry to the Stage 1 plant, however it
has been designed to provide higher quality product and improved recovery. This is achieved by:
● | Washing of solid precipitates in the polishing circuit to minimize Li loss. |
● | Inclusion of improved ultra-fine filtration technology in the polishing circuit will contribute to product quality. |
● | Removal of trace Ca and Mg by ion exchange [IX] processing of carbonation reactor feed will contribute to product quality and an anticipated improvement from technical to battery grade. |
● | Improved control of washing and filtration of final product using air blown plate and frame filters, also contributing to improved quality by minimizing entrained impurities in the cake moisture. |
● | Improved process control by enhanced instrumentation and increased process buffer storage. |
A gas fired rotary drying kiln has been used in the Olaroz II drying plant, along with additional micronizing capacity. A new soda ash bag storage area and mixing plant with the capability to convert to bulk delivery has been designed. Additional raw water wells in the Archibarca alluvial field and downstream reverse osmosis plant capacity are provided to meet the increased clean water requirements. Extended water supply rights have been obtained in the northern Rosario River alluvial sediments. The required increase in power generating capacity is provided by expansion of the stage 1 gas fired generators and additional boiler capacity for solution heating.
14.2.4.1 | Soda Ash Plant |
Soda ash is used in the carbonation and filtering process, as well as in the clarification and polishing process. A new soda ash building is being installed where the raw material will be stored in silos and the soda ash solution used in the process of obtaining lithium carbonate will be prepared.
The auxiliary services required for the operation of this plant are:
● | Weak filtrate (sourced from existing and new lithium carbonate plants). |
● | RO water (used to prepare the solution when weak filtrate is not available). |
● | Hot Water (as a thermic requirement to heat the solution to be prepared). |
● | Process Water (for emergency showers/eye wash and service stations). |
Olaroz Lithium Facility
SEC Technical Report Summary
Operational drains from the equipment are sent to an effluent collection chamber through troughs. The collected effluent is then sent to evaporation basin 1A through a vertical pump.
14.2.4.2 | Carbonation Plant |
The Lithium Carbonate plant is separated into areas:
Area 16250 – Clarification and Polishing: Magnesium and calcium are precipitated to achieve final product specification. Slaked lime (Ca(OH)2) is added to the recycled clarifier underflow, also called the seed recycle (i.e., MaxR® technology). The seed recycle stream is then introduced with fresh brine feed into the first reactor for the precipitation of magnesium. Soda ash solution is added for the precipitation of calcium. pH is monitored and controlled in both reactors by the addition of caustic soda solution.
The resulting slurry is clarified and filtered to produce a purified brine solution for Li2CO3 precipitation. Clarifier overflow is sent for polishing with FLSmidth’s Granular Media Filter (OTG). Process solution is used to backwash the OTG and returned to the clarifier feed. OTG filtrate, polished brine, is sent to Ion Exchange (IX). A bleed of the clarifier underflow is filtered in a pressure filter. The pressure filter’s filtrate is returned to the clarifier feed and the filter cake is repulped and sent to Halite Pond 21A.
The sequence of reactions is indicated in Table 14-1.
Table 14-1 – Sequence of reactions in the clarification and polishing stage.
1st Reaction: | Ca(OH)2 + MgCl2 = CaCl2 + Mg(OH)2 (s) | (Mg Precipitation) |
2nd Reaction: | Ca(OH)2 + Na2SO4 = 2NaOH + CaSO4 | (Max 600ppm Ca in solution) |
3rd Reaction: | Ca(OH)2 + Na2SO4 +2H2O = 2NaOH + CaSO4.2H2O (s) | (Gypsum formation) |
4th Reaction: | Na2CO3 + CaCl2 = CaCO3(s) + 2NaCl | (Ca precipitation) |
5th Reaction: | Na2CO3(aq) = 2Na+(aq) + CO3-(aq) | (Excess Na2CO3) |
Area 16230 – Carbonation and Filtration: Lithium is precipitated as Li2CO3 from the purified and polished brine solution using soda ash solution. The precipitated slurry is then filtered via FLSmidth’s Pneumapress. The filter cake is washed with RO water.
Reaction: | Na2CO3 + 2LiCl = Li2CO3 (s) + 2NaCl |
Area 16240 – Lithium Carbonate Drying: Wet filter cake, after washing, is dried to remove entrained moisture. Natural gas is burnt to provide the heat required to evaporate entrained water in the filter cake.

The expansion of lithium carbonate production entails an increase in electricity to operate both the process units and services. New generators were installed at the plant to meet the new demand for electricity. The current power plant has 10 generators plus 3 new natural gas-fired generators. A new power plant is installed with 9 new generators and space to install 1 more. Electricity generation is provided by the company Secco, under a contract that includes equipment, materials, instructions and labor for electric power generation and cogeneration at Olaroz II. The generation plant is composed of natural gas generation units. Olaroz has a contract for an electric power generation system for the different operations throughout the mining operation:
● | Olaroz I: 13 generator units, 10,45 MW. |
● | Olaroz II: 9 generator units, 17,18 MW. |

14.4.2 | Natural gas |
Natural gas will be required in the following operations:
● | Electrical generation, as described above, where each generator consumes 5,820 Sm3/d (230 Nm3/h) of natural gas. |
● | Hot water circuit: The Lithium Carbonate and soda ash solution preparation plant (SAS Plant) contain plate type heat exchangers, which must be fed with hot water to deliver thermal energy to the fluid to keep the purified brine hot and prevent crystallization of soda ash solution within the process piping, as well as, to heat demineralized water for the process in the Brine Carbonation and Filtration stage. |
● | This is achieved through a closed hot water circuit that takes advantage of the heat of the fumes produced in the electric generators to heat the water that will be supplied to these plants. |
● | An auxiliary boiler will be used, which operates in case of system failure, supplying the essential thermal consumption. This boiler operates with natural gas. The equipment consumption is estimated at 8,279 Sm3/d (327 Nm3/h). |
● | Lithium carbonate production: In the lithium carbonate production process, the product is fed to a rotary dryer to remove moisture content from the final product. This equipment operates on natural gas, with an expected consumption of 1,597 Sm3/d. |
The consumption rates of natural gas can be found on Table 14-4.

Water supply is from a 5-hole wellfield in the north of the Archibarca alluvial sediments. This is pumped to the plant for process use and purification by three reverse osmosis plants into clean water for product washing and ablutions requirements. Potable water is transported from Jujuy by truck. A new water supply wellfield is being established in the Rosario Delta area north of the salar, to provide greater long term water supply and security.

SEC Technical Report Summary
14.6 | Conclusion |
The described recovery and conversion process design is reasonable and implementable. The process is proven to produce saleable lithium carbonate products from Olaroz 1 plant since 2015 with a similar process considered for Olaroz Stage 2, incorporating operational and process enhancements. The process design is based on conducted test work and reflects the related test work parameters. The ponds and process related equipment are suitably sized and organized to produce the mentioned products at the specified throughput. The reagent and commodity consumption rates are deemed appropriate for the size of plant.
14.7 | Recommendations |
As of the effective date, Olaroz Stage 2 is currently in the pre-commissioning and commissioning stage. This stage consists of verifications prior to start-up that ensures equipment and construction conformance to safe design. Pre-commissioning and commissioning activities will ensure in order of importance.
● | The safety of people, the environment and company assets. |
● | The integrity and operation of the equipment. |
● | Efficient execution to reach commissioning without setbacks or delays. |
During operations, it will be necessary to monitor and control critical elements in the brine solutions to minimize impurity impact and maximize quality lithium recoveries. For optimization of lithium recovery operations, there are several technologies that should be evaluated as alternatives to ensure the company’s long-term future production. In particular, the carbonation plan effluent, called “mother liquor”, is recirculated in the process, discharging it again to the evaporation pond circuit. This mother liquor stream still contains some lithium concentration, which is not lost when being recirculated, but at the same time any impurities that this stream may have, are also incorporated to the evaporation pond circuit. In order to improve this recovery process, it is recommended to evaluate alternatives that allow to recover as lithium as possible from this mother liquor stream but leaving the other elements or impurities behind to avoid their recirculation.

15.1 | Property Access |
Olaroz can be accessed directly via road from nearby population centers where established local airports exist.
15.1.1 | Road Access |
Olaroz is located in the Puna area of northwest Argentina, within the province of Jujuy. The main road access to Olaroz is from the city of San Salvador de Jujuy, along the Ruta Nacional (RN) 9, which heads northwest for approximately 60 km, and then meets RN 52 below the town of Purmamarca.
Following Route 52 for 50 km leads to the eastern side of the Salinas Grandes salar. The road crosses this salar before ascending further and after the town of Susques continues south along the eastern margin of the Olaroz salar. It then crosses west where the Olaroz and Cauchari Salars meet. The total distance between the city of Jujuy and Olaroz is approximately 180 km, approximately 4 hours driving. This good quality paved road continues on to the Chilean border at the Jama Pass and connects to the major mining center of Calama and the ports of Antofagasta and Mejillones in northern Chile. Driving distance to these ports is approximately 500 km and 570 km, respectively. This road is fully paved, from Jujuy to these Chilean ports. The Olaroz process plant and facilities are located north of Route 52, with the access to Olaroz via a gravel road north along the western side of the Olaroz salar.
Olaroz may also be accessed from the provincial capital of Salta by driving 27 km WSW from Salta to Campo Quijano, then continuing north for approximately 120 km along Route 51, through Quebrada del Toro, to the town of San Antonio de los Cobres, at an altitude of 3,750 masl. This route is paved, with the exception of the lower section through Quebrada del Toro and the upper section leading to San Antonio. From San Antonio de los Cobres, Route 51 leads west to the south of the Cauchari salar, with route RP 70 providing access along the western side of the Cauchari Salar to reach the international road (RN 52). The distance from San Antonio to Olaroz is approximately 140 km entirely on moderate to well-maintained gravel roads.
15.1.2 | Flights |
Both Jujuy and Salta have regular flights to and from Buenos Aires, Argentina and Sau Paulo, Brazil.
Olaroz Lithium Facility
SEC Technical Report Summary
15.1.3 | Nearest population centers |
There are a number of local villages within 50 kilometers of Olaroz site. These include the villages of Olaroz Chico, El Toro, Catua, and Sey. The regional administrative center of Susques (population around 2000 people) is one hour’s drive northeast of Olaroz site.
15.2 | Site Roads |
A large network of gravel access roads and platforms has been developed throughout the wellfields. Gravel roads are also present around the process and service infrastructure.
15.3 | Electrical Power Supply and Distribution, and Fuel |
The electrical power for the site is generated on a contract basis in a Secco gas fired generator plant. The gas is also used for drying products, and, via boilers, steam heating process solutions as required. Refer to Chapter 14 for more details.
15.4 | Water Supply |
The process plant requires industrial and pure water. Industrial water is used directly from the alluvial production wells, and pure water is obtained from the reverse osmosis water treatment plant located near the lithium carbonate plan, raw water.
Industrial or raw water is obtained from production wells installed in the Archibarca alluvial fan area to the south-southeast of the plant. Two new high yield wells have been installed in the Rosario Delta area in addition to the original 5 water wells in the Archibarca area to enable the construction of the expansion ponds and provide the additional process plant demand. This water is used for:
● | Moistening of earthwork material for structural fills during construction of ponds and plant platforms (during the construction phase). |
● | Irrigation and dust control on work fronts during the construction phase. |
● | Water dilution for transfer pumps is used to transfer brine from one pond to another. |
● | Feeding the RO plants, and the lithium carbonate and liming plants. |
Olaroz Lithium Facility
SEC Technical Report Summary
15.4.1 | Fire Water |
A fire protection system for Olaroz includes industrial water storage tanks feeding the plant´s water network. This system also includes a pump system (electrical and diesel), able to maintain a constant pressure in the network, guaranteeing water supply. The plant will be surrounded by a perimeter closure, which will be constructed with material obtained from the excavation of the area.
15.4.2 | Sewage |
For the management of sewage or sewage effluents, there is a modular sewage effluent treatment plant with physical, chemical, and bacteriological treatment appropriate to the quality and quantity of the effluent generated by the operation. This plant treats all sewage and wastewater generated in restrooms, bathrooms, and camp kitchens. Industrial waste yards and warehouses are provided for waste separation, destruction, and storage, according to its specifications (hazardous and non-hazardous), and a proportion is transported to an authorized disposal center.
15.5 | Construction Materials |
Olaroz construction materials can be roughly separated into two different areas. The wellfield and ponds, and the industrial area. The materials of construction are typical industrial materials well known and associated with lithium brine extraction and processing. The materials have been well tested as part of Olaroz I plant.
The brine wells comprise mainly the well casing, its pump, manifold, and its electrical equipment. Brine pipelines are composed of plastic materials (e.g., HDPE). The ponds are constructed through an earthwork platform and associated embankments. Ponds and lined with LLDPE, HDPE materials typically associated with lined ponds.
Bulk materials in the process area typically include concrete foundations and pavements, steel structures and supports, steel and plastic piping, steel cables trays and insulated copper wiring.
Processing equipment such as thickeners, conveyors, cyclones, boilers, compressors, pumps, filters, steel and plastic tanks, agitators, centrifuges, bagging equipment, heat exchangers, are composed of suitable materials specified by the equipment fabricators. Process piping and equipment material and linings are suitable for the associated chemical composition of the contained liquid e.g., acid, hydroxide, and brine. Salt crystallization and deposition in pipelines remain a risk that is partially dealt with through introduction of smooth internal surfaces and minimizing areas where crystal formation can commence e.g., pipe welds. Plastic piping material is preferred, but well-known exotic steels are used where applicable. Most of these materials require certain engineering progress to be specified, and at the same time they are not produced in Argentina, requiring importation.
Olaroz Lithium Facility
SEC Technical Report Summary
Backfill materials for roads must comply with a percentage of fines under mesh Nº200 ASTM of no more than 12%. The use of materials containing remains of vegetation, garbage and debris from construction work will not be allowed. Berms constructed between ponds also serve as roads for truck circulation during pond harvesting, and transit for monitoring and maintenance activities. Some berms will be wider and constitute the main service roads for salt harvesting activities.
Within the backfill properties for the backfills, it has been considered to use clean gravelly sand from the excavation of the zone called Type 1, as it is the most economical suitable material available (considering a maximum aggregate size of 4” and a percentage of fines passing the n°200 mesh no greater than 15%). The Type 1 Zone represents a predominant subsoil of gravelly sands with subrounded, subangular, and grooved cobble clasts of alluvial origin in an overall matrix of coarse sand, with medium to high compactness in relation to the depth, of homogeneous structure. If this option is not chosen, backfill materials for roads must comply with having a percentage of fines under mesh nº200 astm of no more than 12%. The use of materials containing remains of vegetation, garbage and debris from construction work will not be allowed.
The superficial thickness of low compactness silty sand will be removed together with bushes and eventual vegetation layer, making an escarpment of approximately 15 cm thick. Next, clean sand will be backfilled in 25 cm thick loose layers, compacted with 6 passes of a 1-ton static vibratory roller, in case it is necessary to reach a certain level. A layer of sandy gravel (gp or gw) of maximum size 1” will be placed on top of this backfill, which will be compacted with 6 passes of vibrating plate for each point, to a thickness of not less than 10 cm.
For compacted fills in the process plant site area, a minimum compaction of 95% of the modified proctor (in case the material passing the n°200 mesh is greater than 12%) or 80% of relative density (in case the material passing the n°200 mesh is less than 12%), as appropriate, will be required. The compaction control of each layer shall be one in situ density per 400 m2 of compacted fill in large areas or with a minimum of one in situ density per layer in more confined areas. The material should be spread in horizontal layers of uniform thickness and should be homogeneously wetted.
The maximum size of the backfill material shall be such that it does not exceed ¼ of the loose thickness of the layers to be compacted. The moisture content, loose layer thickness and number of passes of the compacting equipment shall be such that the minimum degrees of compaction determined in the tests for the material present in zone type 1 are achieved.
15.6 | Communication |
Communications are via satellite with good bandwidth, internet and mobile phone coverage. Mobile UHF radios are carried by almost all personnel. A landline telephone network is also available.

SEC Technical Report Summary
15.7 | Security |
The site has a porter’s lodge, whose function is to control the entry and exit of people and vehicles to and from Olaroz. They also perform breathalyzer tests on all vehicle drivers and passengers, in addition to checking for the absence of alcoholic beverages and perishable foodstuffs.
A patrol, a group of people who go around the camp to observe, control and/or report to maintain order and security in the sector, is implemented. These patrols are carried out at random times, both day and night, throughout the Sales de Jujuy area (operations and expansion), on foot or by vehicle, with emphasis on specific points. There are also surveillance cameras on the premises.
15.8 | Waste Storage/Disposal |
Refer to Chapter 17 for discussion on waste management.
15.9 | Conclusion |
The Olaroz 1 processing facility and related service infrastructure has been operational since 2015 and has proven effective. The Olaroz 2 expansion includes both processing and service infrastructure of which construction is nearing completion.
A project water supply currently exists in the Archibarca alluvial gravels to the southwest of the plant and ponds. This has been supplemented by additional water supply from north of the salar. Evaluation of water resources indicates there is sufficient water to support the Stages 1 and 2 operations.
Olaroz infrastructure is reflective of the required processing and support infrastructure and deemed adequate to sustain the safe production of lithium carbonate.

16. Market Studies And Contracts
The information on the lithium market is provided by Wood McKenzie, a prominent global market research group for the chemical and mining industries. Wood Mackenzie, also known as WoodMac, is a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries.
Supplementary comments are provided by the Allkem internal marketing team based on experience with Olaroz product marketing.
16.1 | Overview of the Lithium Industry |
Lithium is the lightest and least dense solid element in the periodic table with a standard atomic weight of 6.94. In its metallic form, lithium is a soft silvery-grey metal, with good heat and electric conductivity. Although being the least reactive of the alkali metals, lithium reacts readily with air, burning with a white flame at temperatures above 200°C and at room temperature forming a red-purple coating of lithium nitride. In water, metallic lithium reacts to form lithium hydroxide and hydrogen. As a result of its reactive properties, lithium does not occur naturally in its pure elemental metallic form, instead occurring within minerals and salts.
The crustal abundance of lithium is calculated to be 0.002% (20 ppm), making it the 32nd most abundant crustal element. Typical values of lithium in the main rock types are 1 – 35 ppm in igneous rocks, 8 ppm in carbonate rocks and 70 ppm in shales and clays. The concentration of lithium in seawater is significantly less than the crustal abundance, ranging between 0.14 ppm and 0.25 ppm.
16.1.1 | Sources of Lithium |
There are five naturally occurring sources of lithium, of which the most developed are lithium pegmatites and continental lithium brines. Other sources of lithium include oilfield brines, geothermal brines, and clays.
16.1.2 | Lithium Minerals |
● | Spodumene [LiAlSi2O6] is the most commonly mined mineral for lithium, with historical and active deposits exploited in China, Australia, Brazil, the USA, and Russia. The high lithium content of spodumene (8% Li2O) and well-defined extraction process, along with the fact that spodumene typically occurs in larger pegmatite deposits, makes it an important mineral in the lithium industry. |
Olaroz Lithium Facility
SEC Technical Report Summary
● | Lepidolite [K(Li,Al)3(Si,Al)4O10(OH,F)2)]is a monoclinic mica group mineral typically associated with granite pegmatites, containing approximately 7% Li2O. Historically, lepidolite was the most widely extracted mineral for lithium; however, its significant fluorine content made the mineral unattractive in comparison to other lithium bearing silicates. Lepidolite mineral concentrates are produced largely in China and Portugal, either for direct use in the ceramics industry or conversion to lithium compounds. |
● | Petalite [LiAl(Si4O10)] contains comparatively less lithium than both lepidolite and spodumene, with approximately 4.5% Li2O. Like the two aforementioned lithium minerals, petalite occurs associated with granite pegmatites and is extracted for processing into downstream lithium products or for direct use in the glass and ceramics industry. |
16.1.2.1 | Lithium Clays |
Lithium clays are formed by the breakdown of lithium-enriched igneous rock which may also be enriched further by hydrothermal/metasomatic alteration. The most significant lithium clays are members of the smectite group, in particular the lithium-magnesium-sodium end member hectorite [Na0.3(Mg,Li)3Si4O10(OH)2]. Hectorite ores typically contain lithium concentrations of 0.24%-0.53% Li and form numerous deposits in the USA and northern Mexico. As well as having the potential to be processed into downstream lithium compounds, hectorite is also used directly in aggregate coatings, vitreous enamels, aerosols, adhesives, emulsion paints and grouts.
Lithium-enriched brines occur in three main environments: evaporative saline lakes and salars, geothermal brines and oilfield brines. Evaporative saline lakes and salars are formed as lithium-bearing lithologies which are weathered by meteoric waters forming a dilute lithium solution. Dilute lithium solutions percolate or flow into lakes and basin environments which can be enclosed or have an outflow. If lakes and basins form in locations where the evaporation rate is greater than the input of water, lithium and other solutes are concentrated in the solution, as water is removed via evaporation. Concentrated solutions (saline brines) can be retained subterraneous within porous sediments and evaporites or in surface lakes, accumulating over time to form large deposits of saline brines.
The chemistry of saline brines is unique to each deposit, with brines even changing dramatically in composition within the same salar. The overall brine composition is crucial in determining a processing method to extract lithium, as other soluble ions such as Mg, Na, and K must be removed during processing. Brines with a high lithium concentration and low Li:Mg and Li:K ratios are considered the most economical to process. Brines with lower lithium contents can be exploited economically if evaporation costs or impurities are low. Lithium concentrations at the Atacama Salar in Chile and Hombre Muerto Salar in Argentina are higher than the majority of other locations, although the Zabuye Salar in China has a more favourable Li:Mg ratio.

16.1.3 | Lithium Industry Supply Chain |
Figure 16-1 below shows a schematic overview of the flow of material through the lithium industry supply chain in 2021. Raw material sources in blue and brown represent the source of refined production and TG mineral products consumed directly in industrial applications. Refined lithium products are distributed into various compounds displayed in green. Refined products may be processed further into specialty lithium products, such as butyllithium or lithium metal displayed in grey. Demand from major end-use applications is shown in orange with the relevant end-use sectors shown in Figure 16-2.
Figure 16-1 – Global Demand for Lithium by End Use, 2023 – 2050 (kt LCE).
Figure 16-2 – Global Demand for Lithium by Product, 2023 – 2050 (kt LCE) (Source: Wood Mackenzie, Q1 2023 Outlook).
Lithium demand has historically been driven by macro-economic growth, but the increasing use of rechargeable batteries in electrified vehicles over the last several years has been the key driver of global demand. Global demand between 2015 and 2021 has more than doubled, reaching 498.2kt LCE with a CAGR of 16.8% over the period. Adding to this growth, in 2022 global lithium demand is expected to increase by 21.3% to 604.4 kt LCE as demand for rechargeable batteries grows further. Over the next decade, global demand for lithium is expected to grow at a rate of 17.7% CAGR to 2,199 kt in 2032.
Olaroz Lithium Facility
SEC Technical Report Summary
16.1.4 | Global demand for Lithium |
Lithium demand has traditionally been used for applications such as in ceramic glazes and porcelain enamels, glass-ceramics for use in high-temperature applications, lubricating greases and as a catalyst for polymer production. Between 2020 and 2022, demand in these sectors rose steadily by approximately 4% CAGR. Growth in these applications tends to be highly correlated to industrial activity and macro-economic growth. Wood Mackenzie forecasts the combined growth of lithium demand from industrial markets is likely to be maintained at approximately 2% per annum from 2023 to 2050.
Rechargeable batteries represent the dominant application of lithium today, representing more than 80% of global lithium demand in 2022. Within the rechargeable battery segment, 58% was attributed to automotive applications which has grown at 69% annually since 2020. This segment is expected to drive lithium demand growth in future. To illustrate, Wood Mackenzie forecast total lithium demand will grow at 11% CAGR between 2023 and 2033: of this lithium demand attributable to the auto-sector is forecast to increase at 13% CAGR; whilst all other applications are forecast to grow at 7% CAGR. Growth is forecast to slow in the following two decades as the market matures.
Lithium is produced in a variety of chemical compositions which in turn serve as precursors in the manufacturing of its end use products such as rechargeable batteries, polymers, ceramics, and others. For rechargeable batteries, the cathode, an essential component of each battery cell, is the largest consumer of lithium across the battery supply chain. Demand profiles for lithium carbonate and hydroxide is determined by the evolution in cathode chemistries. The automotive industry mainly uses NCM and NCA cathodes, often grouped together as “high nickel”; and LFP cathodes. High nickel cathodes consume lithium in hydroxide form and generally has a higher lithium intensity; whilst LFP cathodes mainly consume lithium in carbonate form and lithium content is lower. LFP cathodes are predominantly manufactured in China.
Lithium in the form of lithium hydroxide and lithium carbonate collectively accounted for 90% of refined lithium demand in 2022. These two forms are expected to remain important sources of lithium in the foreseeable future reflecting the share of the rechargeable battery market in the overall lithium market. The remaining forms of lithium include technical grade mineral concentrate (mainly spodumene, petalite and lepidolite) used in industrial applications accounting for 7% of 2022 demand; and other specialty lithium metal used in industrial and niche applications.
Lithium products are classified as ‘battery-grade’ (“BG”) for use in rechargeable battery applications and ‘technical-grade’ (“TG”) which is primarily used in industrial applications. TG lithium carbonate can also be processed and upgraded to higher purity carbonate or hydroxide products.
Lithium hydroxide is expected to experience exponential growth on the back of high-nickel Li-ion batteries. Demand for BG lithium hydroxide is expected to grow at 10% CAGR 2023-2033 to reach 1,133kt LCE in 2033, up from 450 kt LCE in 2023. Wood Mackenzie predict lithium hydroxide to be the largest product by demand volume in the near term. However, growth of LFP demand beyond China may see BG lithium carbonate reclaim its dominance.
Olaroz Lithium Facility
SEC Technical Report Summary
Wood Mackenzie forecast LFP cathodes will increase its share of the cathode market from 28% in 2022 to 43% by 2033. This drives growth in lithium carbonates demand. Wood Mackenzie predicts lithium carbonate demand will grow at 14% CAGR between 2023 and 2033; slowing as the market matures.
16.1.5 | Market Balance |
The lithium market balance has shown high volatility in recent years. A large supply deficit resulted from historical underinvestment relative to strong demand growth in EVs. The rise in prices over the last few years has incentivized investment in additional supply. However, the ability for supply to meet demand remains uncertain given the persistence of delays and cost increases across both brownfield and greenfield developments.
For BG lithium chemicals, Wood Mackenzie predicts the market will remain in deficit in 2024. In 2025, battery grade chemicals are expected to move into a fragile surplus before falling into a sustained deficit in 2033 and beyond. Notably, technical grade lithium chemicals may be reprocessed into battery grade to reduce the deficit. However, the capacity and ability to do so is yet unclear.
16.2 | Lithium Prices |
Lithium spot prices have experienced considerable volatility in 2022 and 2023. Prices peaked in 2022, with battery grade products breaching US$80,000 / t. However, spot prices fell significantly during the Q1 2023 before stabilizing in Q2 2023. A combination of factors can explain the price movements including the plateauing EV sales, slowdown of cathode production in China; and destocking through the supply chain, partially attributed to seasonal maintenance activities and national holidays.
Contract prices have traditionally been agreed on a negotiated basis between customer and supplier. However, in recent years there has been an increasing trend towards linking contract prices to those published by an increasing number of price reporting agencies (“PRA”). As such, contracted prices have tended to follow spot pricing trends, albeit with a lag.
16.2.1 | Lithium Carbonate |
Continued demand growth for LFP cathode batteries will ensure strong demand growth for BG lithium carbonate. This demand is expected to be met predominantly by supply from brine projects. Given the strong pricing environment, a large number of projects have been incentivized to come online steadily over the coming years. Wood Mackenzie forecast prices to decline as additional supply comes online. However, Wood Mackenzie forecasts a sustained deficit in battery-grade lithium chemicals to commence from 2031. Over the longer term, Wood Mackenzie expect prices to settle between US$26,000/t and US$31,000 / t (real US$ 2023 terms).
Olaroz Lithium Facility
SEC Technical Report Summary
Notably, the market for BG carbonates is currently deeper and the spot market more liquid than hydroxide due to the size and experience of its main market of China. In addition, BG carbonates are used in a wider variety of batteries beyond the EV end use. TG lithium carbonate demand for industrial applications is forecast to grow in line with economic growth. However, TG lithium carbonate lends itself well to being reprocessed into BG lithium chemicals (either BG carbonate or BG hydroxide). The ability to re-process the product into BG lithium chemicals will ensure that prices will be linked to prices of BG lithium chemicals.
Figure 16-3 – Lithium Carbonate Price Outlook, 2023 – 2050 (Source: Wood Mackenzie, 1Q 2023 Outlook).
16.2.2 | Lithium Hydroxide |
The market for BG lithium hydroxide is currently small and relatively illiquid compared to the carbonate market. Growth in high nickel cathode chemistries supports a strong demand outlook. Most BG hydroxide is sold under long term contract currently, which is expected to continue. However, contract prices are expected to be linked to spot prices and therefore are likely to follow spot price trends albeit with a lag. Over the longer term, Wood Mackenzie expects hydroxide prices to settle at between US$25,000 and US$35,000 / t (real US$ 2023 terms).

Figure 16-4 – Lithium Hydroxide Price Outlook, 2023 – 2050 (Source: Wood Mackenzie, 1Q 2023 Outlook).
16.2.3 | Chemical grade spodumene concentrate. |
In 2022, demand from converters showed strong growth resulting in improved prices. After years of underinvestment, new capacity has been incentivized and both brownfield and greenfield projects are underway. Notably, these incremental volumes are observed to be at a higher cost and greater difficulty, raising the pricing hurdles required to maintain supply and extending timelines for delivery.
Wood Mackenzie forecasts a short period of supply volatility in the years to 2030, moving from surplus to deficit, to surplus before entering a sustained deficit beyond 2031. Reflecting this dynamic, prices are expected to be in line with market imbalances. Wood Mackenzie forecasts a long-term price between US$2,000/t and US$3,000/t (real US$2023 terms).

SEC Technical Report Summary
16.4 | Market Risk and Opportunities |
16.4.1 | Price Volatility |
Recent pricing history demonstrates the potential for prices to rise and fall significantly in a short space of time. Prices may be influenced by various factors, including global demand and supply dynamics; strategic plans of both competitors and customers; and regulatory developments.
Volatility of prices reduces the ability to accurately predict revenues and therefore cashflows. At present, Allkem’s agreements include index-based or floating pricing terms. In a rising market, this results in positive cashflows and revenues. In a falling market the financial position of the company may be adversely impacted. Uncertainty associated with an unpredictable cashflow may increase funding costs both in debt and equity markets and may therefore impact the company’s ability to invest in future production. Conversely, a persistently stronger pricing environment may also permit self-funding strategies to be put into place.
16.4.2 | Macroeconomic conditions. |
Allkem produces lithium products which are supplied to a range of applications including lithium-ion batteries, the majority being used within the automotive sector and energy storage systems; industrial applications such as lubricating greases, glass, and ceramics; and pharmaceutical applications. Demand for these end uses may be impacted by global macroeconomic conditions, as well as climate change and related regulations, which in turn will impact demand for lithium and lithium prices. Macroeconomic conditions are influenced by numerous factors and tend to be cyclical. Such conditions have been experienced in the past and may be experienced again in future.
16.4.3 | Technological developments within battery chemistries. |
The primary growth driver for lithium chemicals is the automotive battery application, which accounts for more than 60% of demand today. Technology within automotive cathodes and cathode chemistries are continuously evolving to optimize the balance between range, safety, and cost. New “Next Generation” chemistries are announced with regularity, which carries the risk that a significant technology could move the automotive sector away from lithium-ion batteries. On a similar note, new technologies could also increase the intensity of lithium consumption. For example, solid state and lithium metal batteries could require more lithium compared to current lithium-ion battery technology. Despite the potential for technological innovations, the impact to the lithium market over the short-medium term is expected to be limited given the extended commercialization timelines and long automotive investment cycles which are a natural inhibitor to rapid technological change.

16.4.4 | Customer concentration |
Allkem is currently exposed to a relatively limited number of customers and limited jurisdictions. As such, a sudden significant reduction in orders from a significant customer could have a material adverse effect on our business and operating results in the short term. In the near term, this risk is likely to persist. As the battery supply chain diversifies on the back of supportive government policies seeking to establish localized supply, in particular in North America and Europe, there will be scope to broaden the customer base, however the size of automakers, the concentration in the automobile industry and the expected market growth will entail high-volume and high-revenue supply agreements. This risk is closely monitored and mitigative actions are in place where practicable.
16.4.5 | Competitive environment |
Allkem competes in both the mining and refining segments of the lithium industry presently. We face global competition from both integrated and non-integrated producers. Competition is based on several factors such as product capacity and scale, reliability, service, proximity to market, product performance and quality, and price. Allkem faces competition from producers with greater scale; downstream exposures (and therefore guaranteed demand for their upstream products); access to technology; market share; and financial resources to fund organic and/or inorganic growth options. Failure to compete effectively could result in a materially adverse impact on Allkem’s financial position, operations, and ability to invest in future growth. In addition, Allkem faces an increasing number of competitors: a large number of new suppliers has been incentivized to come online in recent years in response to favorable policy environment as well as higher lithium prices. The strength of recent lithium price increases has also incentivized greater investment by customers into substitution or thrifting activities, which so far have not resulted in any material threat. Recycling will progressively compete with primary supply, particularly supported by regulatory requirements, as well as the number of end-of-life battery stock that will become available over the next decade as electric vehicles or energy storage systems are retired.

17. Environmental Studies, Permitting, Social Or Community Impacts
The following section describes the updated environmental, permitting, and social contexts of the Olaroz.
It is the responsible QP’s opinion that the current plans for environmental compliance, permitting, and social and community factors relating to Allkem subsidiary Sales de Jujuy are adequate and in compliance with all Federal and local regulations for the Olaroz project, and that Sales de Jujuy has taken a proactive approach when dealing with the local communities in social engagement that is adequate.
Environmental Studies have been prepared and submitted prior to and during the life of the project and related to the different stages (I&II). An Environmental monitoring plan is in place and continues to be updated.
The project is approved by local communities and local government authorities. It provides positive social and socio-economic benefits for local communities. Sales de Jujuy provides a range of support services to the local communities, ranging from provision of communications facilities in communities to construction of community buildings. The company has developed a closure and reclamation plan for the project, which has been approved by the relevant mining authorities and which will evolve during the life of the project. The estimated closing and reclamation cost is US$39.3M. The Olaroz project is not a metalliferous mining project. There are no sulfide minerals which could weather and produce acid rock drainage outcomes. The waste products of the project are naturally occurring salts, which are already present at the surface of the salar.

17.4 | Environmental Considerations |
Olaroz is located in the Olaroz Cauchari Fauna and Flora Reserve, that was created in 1981 under provincial law 3820. The reserve is a multi-use area that allows for agricultural and mining activities and scientific investigation programs. The operation of Olaroz is consistent with the multi-use reserve status.
17.5 | Social and Community Considerations |
SDJ has been actively involved in community relations since the properties were acquired in 2008. Although there is minimal habitation in the area of the salar, SDJ has consulted extensively with the local aboriginal communities and employs a significant number of members of these communities in the current operations. The Olaroz permitting process addressed community and socio-economic issues. The Olaroz Stage 2 expansion provided new employment opportunities and investment in the region, which is expected to be positive.
Olaroz identifies areas of direct and indirect influence in its Environmental Impact Assessment, however, as a matter of Allkem policy and since its inception in 2008, it has worked with the 10 indigenous communities in the department of Susques: Olaroz Chico, Portico de los Andes Susques, El Toro Rosario, Huáncar, Manantial de Pastos Chicos, Termas de Tuzgle de Puesto Sey, San Juan de Quillaques, Coranzulí, Catua and Paso de Jama.
Olaroz Lithium Facility
SEC Technical Report Summary
17.6 | Mine Closure and Reclamation Plant |
SDJ has submitted two mine closure plans within the Environmental Impact Assessment evaluation processes, the first one on 20/03/2013 and the second one on 07/11/2017.
Both plans approved by the Mining Provincial Directorate include the design and implementation of different measures such as decommissioning, physical, and chemical stabilization, land reclamation or rehabilitation, revegetation and post-closure monitoring measures and actions. From a social perspective, it includes social programs aimed at mine workers and the population of the communities interrelated to the mine. They must be updated in the next renewal of the Environmental Impact Assessment, all in accordance with the provisions of Decree No. 7751/23.
Sales de Jujuy has made provision as described in Section 18 for those expenses that may be incurred to execute the Mine Closure Plans submitted to the authority. This calculation, which was made by an external consultant “WSP - Golder Associates Argentina S.A.” and in accordance with NIC37 standards and the Manual for the Application of IFRS standards in the mining sector, must be made available to the provincial enforcement authority in the next renewal of the Environmental Impact Assessment, as indicated above.
In addition to these specific plans for the closure of Olaroz, SDJ has an Environmental Contingency Plan that establishes the policies, objectives, plans, actions, procedures, and indicators necessary for the development of its operations in an environmentally compatible manner and in compliance with applicable national, provincial, and municipal environmental legal requirements. In addition to these specific plans for the closure of Olaroz , Allkem has an Environmental Contingency Plan that establishes the policies, objectives, plans, actions, procedures, and indicators necessary for the development of its operations in an environmentally compatible manner and in compliance with applicable national, provincial, and municipal environmental legal requirements. This Plan is the minimum standard to be met by all personnel associated with the activities carried out at the mine (own personnel, contractors, service providers, auditors, inspectors and/or visitors) and at all sites of the mining operation and is submitted together with the Environmental Impact Assessment and updated with each renewal.
Finally, Allkem carries out participatory and quarterly environmental monitoring campaigns, sampling almost 50 representative points of fauna, flora, soil, climate, water, effluents, limnology, air quality, noise, limnology, landscape characteristics and ecosystem characterization, etc. Then, the reports of the results of these points are submitted to the Provincial Directorate of Mining, which evaluates them according to emission and legal conservation parameters and issues the corresponding approval.
Of the staff employed from Jujuy province, approximately 52% are from nearby communities: Coranzulí, El Toro, Huancar, Jama, Olaroz Chico, Puesto Sey, San Juan de Quillaques, Susques and Catua. For the 2022/2023 period, 186 people were incorporated.
Olaroz Lithium Facility
SEC Technical Report Summary
17.7 | Conclusion |
Olaroz has commenced operations since 2013. Olaroz received approvals for the construction of Stage 1 and Stage 2 from the relevant provincial and federal agencies and operates with a series of permits and approvals that cover operations, registration with authorities, use of chemicals and fuels, waste generation and disposal construction and operation of the water pipelines, disposal of effluents, and extraction of gravels as examples of the permits.
Olaroz has fulfilled the required environmental and social assessments. Olaroz is fully permitted by the provincial mining authorities and has provincial and federal permits, to allow operations for an initial forty (40) year mine life, with renewable options in 2035.
The operation reflects positive social and socio-economic benefits for local communities.
The Olaroz lithium facility has established relationships with the surrounding communities, from where an important portion of the operations workforce is drawn. The operation has a policy of preferentially sourcing goods and services from the local community and from within the province. The operation also operates a number of schemes providing grants to the local community in order to start new businesses in the area and to improve the lives of the local community residents. Such schemes include construction of sports and other facilities in the nearby local villages in what is overall a very sparsely populated area.
17.8 | Recommendations |
Ongoing social development will enhance the importance of the lithium industry in the area. The lithium production industry is seeing increased extraction development with competing mines establishing in close proximity. Enhanced engagement between such mines can ensure alignment of social development plans that will best benefit the incumbent communities.
Continual engagement with local authorities is recommended to ensure changes in legislation, administrative errors or omissions and changes in political office holders are proactively managed and issues addressed. Continual environmental monitoring, reporting and compliance is best managed proactively toward bi-annual license renewals to minimize any potential delays.

18. Capital And Operating Costs
This chapter outlines the capital and operational costs for the Olaroz lithium facility. Every cost forecast is delineated on a yearly basis for the Olaroz life of mine. Olaroz stands as an operating mine, and the capital cost does not consider expenditures that have already been absorbed by Allkem in the prior development phases, also called sunk costs.
All estimates outlined herein are expressed in FY2024 prices. All projections are estimated in real terms, they do not incorporate allocations for inflation, financial expenses, and all financial assessments are expressed in US dollars.
The ongoing and proven lithium carbonate production at Olaroz 1, the advanced stage of Olaroz 2 construction and commissioning, and recent market information provide Allkem with sufficiently accurate estimation rigor to develop this report to a suitable level where both capital and operating cost accuracy is ±15% and contingency is less than or equal to 10% as defined by the SK Regulations, with remaining uncertainty associated with an expected 40-year life-of-mine.
18.1 | Estimate Basis |
The Olaroz Stage 2 expansion project overall construction progress reached 99.5% completion in June 2023. As of July 2023, the project achieved Mechanical Completion and is progressing towards commissioning of the Carbonation Plant, with block wet commissioning underway and production ramp up anticipated in the following months. Olaroz’ commissioning schedule included commissioning of different areas including wells, ponds, liming plants, and most of the Balance of Plant (BOP). The Capital expenditures for Olaroz Stage 2 were estimated for a plant capacity of 25,000 tonnes of lithium carbonate per year.
The capital cost estimate shown here was prepared by Worley Argentina S.A. (Collectively, Worley) in collaboration with Allkem. The estimate includes capital cost estimation data developed and provided by Worley, Allkem and other third-party contractors in accordance with individual scope allocations.
The capital cost was broken into direct and indirect costs.
18.2 | Direct costs |
This encompasses costs that can be directly attributed to a specific direct facility, including the costs for labor, equipment, and materials. This includes items such as plant equipment, bulk materials, specialty contractor’s all-in costs for labor, contractor direct costs, construction, materials, and labor costs for facility construction or installation.
18.3 | Indirect costs |
Costs that support the purchase and installation of the direct costs, including temporary buildings and infrastructure; temporary roads, manual labor training and testing; soil and other testing; survey, engineering, procurement, construction, and project management costs (EPCM); costs associated with insurance, travel, accommodation, and overheads, third party consultants, Owner’s costs, and contingency.

● | Basic design (engineered conceptual designs). |
● | Estimates from plot plans, general arrangements or previous experience, and order of magnitude allowances. |
● | Experience based on Olaroz construction and operation. |
Estimate pricing was derived from a combination of:
● | Budget pricing that included an extensive budget quotation process for general and bulk commodities. |
● | Fixed quotations for major equipment, and budget quotations for all other mechanical equipment. |
● | Historical pricing from the Olaroz operation. |
● | Estimated or built-up rates and allowances. |
● | Labor hourly costs based on the current Olaroz operation site. Please refer to the quarterly activities report. |
The estimate considers execution under an EPC approach.
The construction working hours are based on a 2:1 rotation arrangement, i.e.: 14 (or 20) consecutive working days and 7 (or 10) days off. The regular working hours at 9.5 hours per day but could be extended up to 12 hours of overtime. Whilst an agreement will need to be reached with the relevant trade unions, this roster cycle is allowed under Argentinian law and has been used for similar projects. Labor at the wellfields, ponds, process plant, and pipelines areas will be housed in construction camps, with camp operation, maintenance, and catering included in the indirect cost estimate. A productivity factor of 1.35 was estimated, considering the Project/site-specific conditions.
Sustaining capital is based on the current sustaining capex and considers some operational improvements such as continuous pond harvesting. Engineering, management, and Owner’s costs were developed from first principles. The Owner’s cost estimate includes:
● | Home office costs and site staffing. |
Olaroz Lithium Facility
SEC Technical Report Summary
● | Engineering and other sub-consultants. |
● | Office consumables, equipment. |
● | Insurance. |
● | Exploration. |
● | Pilot plant activities and associated project travel. |
The estimate for engineering, management and Owner’s costs was based on a preliminary manning schedule for anticipated Project deliverables and Project schedule. Engineering design of the estimate for the home office is based on calculation of required deliverables and manning levels to complete the Project.
18.5 | Summary of Capital Cost Estimate |

19. Economic Inputs and Assumptions
This section analyzes Olaroz economic feasibility. Certain information and statements contained in this section and in the report are forward-looking in nature. Actual events and results may differ significantly from these forward-looking statements due to various risks, uncertainties, and contingencies, including factors related to business, economics, politics, competition, and society.
Forward-looking statements cover a wide range of aspects, such as project economic and study parameters, estimates of Brine Resource and Brine Reserves (including geological interpretation, grades, extraction and mining recovery rates, hydrological and hydrogeological assumptions), project development cost and timing, dilution and extraction recoveries, processing methods and production rates, metallurgical recovery rate estimates, infrastructure requirements, capital, operating and sustaining cost estimates, estimated mine life, and other project attributes. Additionally, it includes the assessment of net present value (NPV) and internal rate of return (IRR), payback period of capital, commodity prices, environmental assessment process timing, potential changes in project configuration due to stakeholder or government input, government regulations, permitting timelines, estimates of reclamation obligations, requirements for additional capital, and environmental risks.
All forward-looking statements in this Report are necessarily based on opinions and estimates made as of the date such statements are made and are subject to important risk factors and uncertainties, many of which cannot be controlled or predicted. Material assumptions regarding forward-looking statements are discussed in this Report, where applicable. In addition to, and subject to, such specific assumptions discussed in more detail elsewhere in this Report, the forward-looking statements in this report are subject to the following general assumptions:
● | No significant disruptions affecting the project’s development and operation timelines. |
● | The availability of consumables and services at prices consistent with existing operations. |
● | Labor and materials costs consistent with those for existing operations. |
● | Permitting and stakeholder arrangements consistent with current expectations. |
● | Obtaining all required environmental approvals, permits, licenses, and authorizations within expected timelines. |
● | No significant changes in applicable royalties, foreign exchange rates, or tax rates related to the project. |
To conduct the economic evaluation of the project, Allkem’s team employed a cash flow model that allows for both before and after-tax analysis. The main inputs for this model include the capital and operating cost estimates presented in the previous chapters, along with an assumed brine production plan, plant performance capability and the pricing forecast outlined in Chapter 16.
Using the cash flow model, the key project indicators have been calculated, including a sensitivity analysis on the most critical revenue and cost variables to assess their impact on the project’s financial metrics.

SEC Technical Report Summary
19.1 | Evaluation Criteria |
For the economic analysis, the Discounted Cash Flow (DCF) method was adopted to estimate the project’s return based on expected future revenues, costs, and investments. DCF involves discounting all future cash flows to their present value using a discount rate determined by the company. This approach facilitates critical business decisions, such Merger & Acquisition (M&A) activities, growth project investments, optimizing investment portfolios, and ensuring efficient capital allocation for the company.
Key points about the Discounted Cash Flow method:
● | The discount rate is based on the weighted average cost of capital (WACC), incorporating the rate of return expected by shareholders. |
● | All capital expenditure incurred to date for Olaroz was considered as sunk costs and excluded from the present value calculations. |
The DCF approach involves estimating net annual free cash flows by forecasting yearly revenues and deducting yearly cash outflows, including operating costs (production and G&A costs), initial and sustaining capital costs, taxes, and royalties. These net cash flows are then discounted back to the valuation date using a real, after-tax discount rate of 10%, reflecting Allkem’s estimated cost of capital.
The DCF model is constructed on a real basis without escalation or inflation of any inputs or variables. The primary outputs of the analysis, on a 100% basis, include:
● | NPV at a discount rate of 10%. |
● | Internal rate of return (IRR), when applicable. |
● | Payback period, when applicable. |
● | Annual earnings before interest, taxes, depreciation, and amortization (EBITDA). |
● | Annual free cash flow (FCF). |
19.2 | Financial Model Parameters |
19.2.1 | Overview |
The financial model is based on several key assumptions, including:
● | Production schedule, including key parameters such as annual brine production, pond evaporation rates, process plant production, and the ramp-up schedule. |
● | Plant recoveries and lithium grades. |
● | Operating, capital, and closure costs for the remaining 32 years of operating life according to current state of permits. |
Olaroz Lithium Facility
SEC Technical Report Summary
● | Operating costs related to wellfields, evaporation ponds, process plant, waste removal, site-wide maintenance and sustaining costs, environmental costs, onsite infrastructure and service costs, and labor costs (including contractors). |
● | Product sales assumed to be Free on Board (FOB) South America. |
19.2.2 | Production Rate |
The Olaroz nominal capacity of annual lithium carbonate is estimated to be 42,500 t/year as described in Chapter 14. This is divided into 17,500 t/year of lithium carbonate from the Stage 1 system which has been operating since 2014, and the anticipated 25,000 t/year of lithium carbonate from the Stage 2 expansion which is approaching hot commissioning and ramp up.
The Table 19-1 summarizes the production quantities, grades, overall recovery, average sale prices, revenues, investments, operating costs, royalties, taxes, depreciation/amortization, and free cash flows on an annual basis with LOM totals, among other things.

19.4 | Indicative Economics and Sensitivity Analysis |
To assess the robustness of the project’s financial results, a sensitivity analysis was conducted in a range of +/- 25% on the key variables that impact the Olaroz’s after-tax net present value (NPV). The sensitivity analysis explores the potential effects of changes in relevant variables, such as:
● | Revenue variables: |
o | Lithium carbonate prices. |
o | Production levels. |
● | Cost variables: |
o | Capital expenditure (CAPEX). |
o | Operating expenses (OPEX). |
The results are graphically summarized in the Table 19-2 and Figure 19-1.
19.5 | Olaroz Sensitivity Analysis |
The sensitivity analysis examined the impact of variations in commodity prices, production levels, capital costs, and operating costs on the project’s NPV at a discount rate of 10%. The aim is to illustrate how changes in these crucial variables affect the project’s financial viability.
The following Table 19-3 and Figure 19-1 provide the insights into the NPV@10% associated with the fluctuations in the key variables.
From the analysis, the commodity price has the most significant impact on the Olaroz’s NPV, followed by production levels, OPEX, and CAPEX. Even under adverse market conditions, such as unfavorable price levels, increased costs, and investment challenges, Olaroz remains economically viable.
The sensitivity analysis focused on individual variable changes, and the combined effects of
multiple variable variations were not explicitly modeled in this analysis.

19.6 | Comments on Economic Analysis |
Based on the assumptions detailed in this report, the economic analysis of Olaroz demonstrates positive financial outcomes. The sensitivity analysis further strengthens its viability, as it indicates resilience to market fluctuations and cost changes. The sensitivity analysis indicates that the greatest project risk is the lithium carbonate price despite the favorable price history of the last two years. Further, unlike production targets, this price risk is not within the control of Allkem.
By conducting this sensitivity analysis, it provides a comprehensive understanding of the project’s financial risks and opportunities. This approach allows for informed decision-making and a clear assessment of Olaroz ‘s potential performance under various economic.

20. Adjacent Properties
20.1 | General Comments |
Olaroz is located directly adjacent to two other lithium Projects, the Cauchari Lithium Project (100% owned by Allkem) is located to the south. The Minera Exar Cauchari Olaroz development Project, owned by Lithium Americas Corp, in joint venture with major Chinese lithium producer Ganfeng, is located to the east and south of SDJ properties.
The employee of Hydrominex Geoscience set forth herein (the QP) has been unable to verify the information from the adjacent Lithium Americas Corp properties and the information is not necessarily indicative of the mineralization on the property that is the subject of the technical report and summary. The employee of Hydrominex Geoscience set forth herein (the principal author) was involved with the evaluation of the South American Salars properties in 2018 and 2019.
20.2 | South American Salars |
The Cauchari Project was explored by Advantage Lithium (Advantage), a Canadian listed company. Advantage undertook an extensive drilling program on the Cauchari properties in joint venture with then Orocobre, on properties owned by Orocobre subsidiary company South American Salars. Information is available from the October 2019 PFS study by that company. Exploration included drilling 29 mostly HQ diamond holes, with the installation of 5 test production wells and additional monitoring wells, to further evaluate sub-surface conditions and undertake pumping tests to determine the hydraulic parameters of the aquifers in the Project. Electrical geophysics was undertaken around the margins of the Cauchari Salar to define the interface between brine and fresh to brackish water in alluvial fans. Pumping tests were undertaken in the five test production wells, establishing the likely extraction rates in different areas of the salar.
A Mineral Resource estimate was undertaken for the Cauchari Project, which assessed that the Cauchari Project contains 4.8 Mt of lithium carbonate as Measured and Indicated Resources and 1.5 Mt of lithium carbonate as Inferred resources. These resources are included in the western and eastern properties directly south of Olaroz.
A reserve was subsequently defined for the Cauchari Project, following the development of a groundwater model for the Project. This was calibrated in steady state mode and in transient mode, using data from the pumping tests conducted in different areas of the salar. The reserve is 1 Mt of lithium carbonate, to be extracted over a 31-year mine life from the Western and Eastern properties in Cauchari. The reserve does not account for losses in evaporation ponds and in the production plant. More detail can be found within the Technical Resource Summary for the Cauchari Project.

SEC Technical Report Summary
20.3 | Lithium Americas (LAC) – Ganfeng |
Lithium Americas Corp (TSX: LAC) owns mineral properties immediately adjacent to the Cauchari mineral properties held by Allkem. In 2018 LAC announced a strategic investment and increased ownership by Ganfeng to advance its Cauchari-Olaroz Project (Exar Project). Ganfeng and LAC currently have ownership in the Exar Project of 44.8% LAC, and 46.7% Ganfeng Lithium, with 8.5% held by JEMSE. An October 2020 NI 43-101 report was released with details of the planned project.
Construction is continuing on the Exar Project with initial planned production and ramp up to production of 40,000 tpa of LCE expected to commence in late 2023. On June 12, 2023, LAC announced production of the first lithium as part of commissioning the plant. On May 7, 2019, LAC announced an expansion of Measured and Indicated Resources to 19.9 Mt (LCE), with an additional 4.7 Mt (LCE) of Inferred resource. Probable and Proven Reserves are estimated at approximately 1.95 Mt of LCE, taking account of a processing efficiency of 53.7%.

Olaroz Lithium Facility
SEC Technical Report Summary
As noted above, the SDJ Olaroz properties adjoin properties owned by LAC/Ganfeng in the east of Olaroz and in Cauchari, with additional properties in Cauchari also owned by Allkem (through South American Salars). The Mineral Resources and Reserves to be exploited are in brine, which is mobile and reacts to pumping from the host sediments. It is highly likely that wells located near the borders of properties will extract brine across these borders. This creates the potential for disagreements between the companies which share the mineral resources contained in the continuous aquifer beneath the Olaroz and Cauchari Salars.
The challenge of adjoining mineral properties with mobile resources beneath them often occurs in oil and gas production, where it is solved via “unitization agreements” among the area concessionaries. Unitization agreements are widespread in the oil and gas industry, including in Argentina. As part of the exploitation of lithium brine in the Olaroz-Cauchari Salars it may become necessary for the companies involved to establish an agreement of this type to manage extraction.
20.4 | Lithium Energy Limited |
Australian company Lithium Energy Limited (ASX:LEL) is exploring the Solaroz project to the northwest of the Olaroz Salar. The project is adjacent to Allkem properties and covers extensive areas of gravels.
Initial drilling on the project has confirmed that lithium-bearing brine extends off the salar into the Solaroz project. LEL has identified a halite unit in their drilling, which is interpreted to be the same halite unit further south in the Olaroz Salar. LEL also encountered sandy material below the halite unit, which is very significant and extremely positive for the prospectivity of the Allkem properties north of the salar and adjacent to LEL.
The results from LEL, together with the gravity geophysical survey, which indicates a thick sequence of basin sediments extending through these northern Allkem properties, makes this area highly prospective and the target of planned Allkem exploration.

22. Interpretation And Conclusions
22.1 | Conclusions |
Olaroz hosts a large lithium resource to support Stages 1 and 2 of the projects. Additional exploration is likely to define additional resources north and south of the existing resources. The project has an operating history from 2013 and a proven lithium production process. There is potential for the expansion of the project and improvement of efficiencies and synergies with expansion and this is currently under evaluation to meet rising market demand.
The study concludes that the operating Olaroz 1 and Olaroz 2 expansion represents economic feasibility. The Olaroz 1 plant has proven effective process design and saleable product quality to support the economic evaluation.
The collected data and models are deemed reliable and adequate to support the mineral resource estimate, cost estimates and the indicated level of study.
22.1.1 | Geology and Resources |
Deeper drilling to support the Stage 2 Olaroz expansion has been completed to depths between 400 and 650 m, depending on location within the basin. This deeper drilling has confirmed that deposition of coarser grained higher porosity and permeability sediments has been principally from the western side of the basin.
The deep drill hole has confirmed the Olaroz Basin extends to greater than 1,400 m in the deeper part of the basin. Drilling to date has not intersected the underlying basement rocks in the basin, confirming the extensive volume of brine saturated sediments present.
Drilling has confirmed that a simplified five-unit hydro stratigraphic model is sufficient to represent the sediments in the salar to the depths currently explored. The lower unit contains a higher sandy content and supports high flow rates, which have been confirmed by pumping since 2016 and in more recent deeper wells. There are no significant changes in brine chemistry identified in the deeper drilling, with similar lithium and other element concentrations and key chemical ratios. Completion of the Stage 2 expansion well program has confirmed high flows and similar brine chemistry to earlier holes in this unit.
An extensive area north of the current day salar surface, beneath alluvial sediments around the side of the basin and the Rosario Delta sediments, is highly prospective for the definition of additional brine resources. However, no drilling (beyond several 54 m deep sonic holes) has been drilled in this area, which will be a future focus of exploration.
Olaroz Lithium Facility
SEC Technical Report Summary
22.1.2 | Resources |
Despite the limited diamond drilling and brine interval sampling below 200 m depth, pumping wells installed to depths up to 650 m and pumping since 2016 confirm the brine quality and flow rates in the deeper parts of the salar. Drilling for the Stage 2 expansion has been between 450 and 650 m depth. These holes were geologically and geophysically logged and a robust stratigraphy has been established for the basin.
The resource was estimated based on a combination of the interval sampling in the upper 200 m and the pumping well data below this depth.
The Qualified Persons consider the salar geometry and geology, brine quality and sediment specific yield have been defined sufficiently to support the classification of the resource as Measured, Indicated, and Inferred resources.
22.1.3 | Metallurgy and Processing |
The described recovery and conversion process design is reasonable and implementable. The process has been proven to produce saleable lithium carbonate products from Olaroz 1 plant since 2015 with a similar process considered for Olaroz 2, incorporating operational and process enhancements. The process design is based on conducted test work and reflects the related test work parameters. The ponds and process related equipment are suitably sized and organized to produce the mentioned products at the specified throughput. The reagent and commodity consumption rates are deemed appropriate for the size of plant.
22.1.4 | Infrastructure and Water Management |
The Olaroz 1 processing facility and related service infrastructure has been operational since 2015 and has proven effective. The Olaroz 2 expansion includes both processing and service infrastructure of which construction is nearing completion.
A project water supply currently exists in the Archibarca alluvial gravels to the southwest of the plant and ponds. This is being supplemented by additional water supply from north of the salar. Evaluation of water resources indicates there is sufficient water to support the Stages 1 and 2 operations.
The project infrastructure is reflective of the required processing and support service infrastructure. The infrastructure is deemed adequate to sustain the safe production of lithium carbonate for both Stages 1 and 2.

SEC Technical Report Summary
22.1.5 | Market Studies |
The Project is relying on third party specialist consultants Wood Mackenzie, a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries. The long-term pricing assessment is deemed suitable for economic evaluation of the Project at the current level of study.
22.1.6 | Environmental and Social Issues |
Olaroz is an operating project since 2013. The project received approvals for the construction of Stage 1 and Stage 2 of the project from the relevant provincial and federal agencies and operates with a series of permits and approvals that cover operations, registration with authorities, use of chemicals and fuels, waste generation and disposal construction and operation of the water pipelines, disposal of effluents, and extraction of gravels as examples of the permits.
The project has fulfilled the required environmental and social assessments. The project is fully permitted by the provincial mining authorities and has provincial and federal permits, to allow operations for an initial forty (40) year mine life, with renewable options in 2035. The project reflects positive social and socio-economic benefits for local communities.
The Project has established relationships with the surrounding communities, from where an important portion of the project workforce is drawn. The Project has a policy of preferentially sourcing goods and services from the local community and from within the province. The Project also operates several schemes providing grants to the local community in order to start new businesses in the area and to improve the lives of the local community residents. Such schemes include construction of sports and other facilities in the nearby local villages in what is overall a very sparsely populated area.
22.1.7 | Project Costs and Financial Evaluation |
The high level of construction completion for the Olaroz 2 facility relays a high level of confidence in the related capital cost. The operational costs are based on real pricing as part of the operational readiness and ramp-up process currently under way at the project site.
The indicated capital and operational costs accurately reflect the incurred and future expected costs for the Olaroz 2 project and can be utilized for economic analysis.
Based on the detailed assumptions, the economic analysis of Olaroz 2 and combined Olaroz 1 and 2 demonstrates positive economic outcomes. The sensitivity analysis further indicates economic resilience to market and cost fluctuations.

In the case of Sales de Jujuy, and since 2009, the evaluation process is carried out with the participation and dialogue of the 10 indigenous communities of the department of Susques.
Olaroz Lithium Facility
SEC Technical Report Summary
22.2.1 | Mineral Resource |
● | Interpretation of the base of the salar is heavily reliant on gravity geophysics, for which multiple interpretations of the data are possible. Definition of the limits of the Olaroz brine body depends on the AMT and VES geophysics. Consequently, there is a risk that the actual geology and thickness of the sediments is different to that interpreted from the geophysical data. |
● | Brine sampling during diamond drilling entails risks of contamination from drilling fluid. Although results from pumping tests on rotary drill holes installed as production wells suggest this is not the case, depth specific brine samples from diamond holes can potentially be contaminated by drilling fluid. |
● | The risk that assays results are not representative of the fluid present in sediments within the properties, due to the relatively small number of samples taken during deeper drilling, despite consistent results between drill holes. |
22.2.2 | Metallurgy and Mineral Processing |
● | The fluid nature of the salar, coupled with evaporation performance and processing fluctuations may not produce the estimated recoveries. Current designs are based on test work and historical data averages. Weather and salar related factors remain risk components. |
● | Unseasonal rainfall could occur, which could temporarily impact production / evaporation projections. |
22.2.3 | Operating Permits and Environment |
● | The risk that properties might not be fully granted or maintained, due to administrative errors or failure to make the annual property payments. |
● | Necessary licenses and permit renewals may not be received from the designated authorities in a timely manner on acceptable terms. |
● | Changes in federal or provincial laws and their implementation, impacting activities on the properties. |
● | Changes in community relations and local political perceptions may impact the periodic or long-term operation over the life-of-mine. |
Olaroz Lithium Facility
SEC Technical Report Summary
22.2.4 | Cost and Economic Analysis |
● | Future changes in lithium price could affect the economics of lithium production or enough lithium required to justify economic extraction. |
● | Input costs related to labor and reagents, or availability of supply, could affect the project economics periodically or permanently. |
● | Economic and political conditions in Argentina could change, such that the country risk profile is different to that which is currently assessed for feasible economic extraction. |

SEC Technical Report Summary
23. Recommendations
23.1 | Geology and Resources |
The authors recommend the planned diamond and rotary drilling program is implemented and monitoring wells are installed across the salar for ongoing monitoring of brine levels and brine concentrations prior to Stage 3 expansion.
All drill holes should be geophysical logged to obtain the maximum possible information from drilling and to assist geological correlation. Physical porosity samples should continue to be taken for comparison with BMR geophysical logs. Monitoring well installation should include installation of wells at different depths, to improve the understanding of the distribution of piezometric heads across and around the salar.
Once additional exploration drilling has been completed the geological model should be updated to reflect the improved understanding from this additional drilling. The Olaroz resource should also be updated at this point, to reclassify additional resources as Measured and Indicated or Inferred, based on increased geological confidence.
Additional pumping test wells should be installed in the area of expanded exploration drilling, to provide information on aquifer conditions. Once pumping tests and the resource model are updated the Olaroz groundwater model should be re-calibrated with the additional data and used to define an updated mineral reserve and the Olaroz production schedule should be updated.
Regular analyses of brine samples should be undertaken using independent external laboratories, to complement the laboratory analyses carried out by the Olaroz laboratory.
Ongoing water level monitoring should establish the changes of the commencement and ongoing operation of pumping by the Exar Project.
23.2 | Metallurgy and Processing |
As of the Effective Date, Olaroz 2 is currently in the pre-commissioning and commissioning stage. This stage consists of verifications prior to start-up that ensures equipment and construction conformance to safe design. Pre-commissioning and commissioning activities will ensue in order of importance:
● | The safety of people, the environment and company assets. |
● | The integrity and operation of the equipment. |
● | Efficient execution to reach commissioning without setbacks or delays. |
During operations, it will be necessary to monitor and control critical elements in the brine solutions to minimize impurity impact and maximize quality Lithium recoveries.
Olaroz Lithium Facility
SEC Technical Report Summary
Operation of the ponds and plant should be monitored, and data analyzed to optimize operations and minimize use of chemical reagents, while optimizing lithium recovery. Use of freshwater in the production process must be monitored and optimized, to allow continuous improvement and reduction in consumption per tonne of lithium product.
For optimization of lithium recovery operations, there are several technologies that should be evaluated as alternatives to ensure the company’s long-term future production. In particular, the carbonation plan effluent, called “mother liquor”, is recirculated in the process, discharging it again to the evaporation pond circuit. This mother liquor stream still contains some lithium concentration, which is not lost when being recirculated, but at the same time any impurities that this stream may have, are also incorporated to the evaporation pond circuit. In order to improve this recovery process, it is recommended to evaluate alternatives that allow to recover as lithium as possible from this mother liquor stream but leaving the other elements or impurities behind to avoid their recirculation.
23.3 | Market Studies |
Market analysis will continue to evolve during the project development phase. It is recommended that Allkem continue with ongoing market analysis and related economic sensitivity analysis.
Risk factors and opportunities in technological advancements, competition and macroeconomic trends should be reviewed for relevancy prior to major capital investment decisions. Remaining abreast of lithium extraction technology advancements, and potential further test work or pilot plant work may provide opportunities to improve the Project economics.
23.4 | Environmental and Social Recommendations |
Ongoing social development will enhance the importance of the lithium industry in the area. The lithium production industry is seeing increased extraction development with competing mines establishing in close proximity. Enhanced engagement between such mines can ensure alignment of social development plans that will best benefit the incumbent communities.
Continual engagement with local authorities is recommended to ensure changes in legislation, administrative errors or omissions and changes in political office holders are proactively managed and issues addressed. Continual environmental monitoring, reporting and compliance is best managed proactively toward bi-annual license renewals to minimize any potential delays.

SEC Technical Report Summary
23.5 | Project Costs and Financial Evaluation |
The Olaroz Stage 2 is nearing completion with most capital costs committed and confirmed. Commissioning and ramp up has been modelled as part of the economics and are deemed realistic and achievable in the opinion of the QPs.
The risk of changes to government acts, regulations, tax regimes or foreign exchange regulation remains and must be reviewed upon enactment. Related risk and change management must be accurately reflected in the Project contingencies or expected economic performance.

SEC Technical Report Summary
1. Executive Summary
1.1 Background
This report discloses the lithium brine mineral resource for Allkem Limited’s (Allkem’s) Sal de Vida Project (Sal de Vida, SDV or “the Project”). The Project is a planned brine mining and processing facility that has commenced construction of processing infrastructure.
In 2022 the Project embarked on the construction and upgrade of the initial 15,000 tonne per annum (tpa) (SDV Stage 1) Lithium Carbonate Equivalent (LCE) production facility and aims to complete construction in the first half of 2025. The Project further plans a modular 30,000 tpa (15,000 tpa + 15,000 tpa) (SDV Stage 2) expansion which is still in the pre-feasibility study phase. The Project aims to produce 45,000 tpa in total from the planned staged expansions.
This report has been prepared in conformance with the requirements of the Securities and Exchange Commission (SEC) S-K Regulation (Subpart 1300) (the “SK Regulations”). This individual Technical Report is the initial report in support of Allkem’s listing on the New York Stock Exchange (NYSE). This report updates project Mineral Resources, cost estimates, and economics as of the report Effective Date (June 30, 2023).
The Stage 1 wellfield, brine distribution, evaporation ponds, waste (wells and ponds) and Stage 1 process plant cost estimates are AACE Class 2 ±10% (with an accuracy of ±10% and contingency less than 10%). Costs for the 30,000 tpa Stage 2 are AACE Class 4 +30% / - 20% (with an accuracy of ±25% and contingency of 15%) with no escalation of costs in the context of long-term product pricing estimates. This report presents separate economics for Stage 1 (15,000 tpa) currently under construction, followed by a combined Stage 1 and Stage 2 (45,000 tpa) economic assessment.
Lithium production has not commenced at the Sal de Vida site as of the Effective Date. As of the Effective Date, SDV Stage 1 construction is approximately 24% complete. Detailed engineering, quantity estimation, contractor pricing, obtained permits, and social aspects are sufficiently progressed to develop this report to feasibility study level estimate for Stage 1 as defined by the SK Regulations.
SDV Stage 2 is sufficiently developed to report on a Pre-Feasibility Study level.
Updated Mineral Resources and Reserves are being reported as production well drilling campaign progression and greater knowledge of the basin and its geologic setting.
Conclusions, recommendations, and forward-looking statements made by QPs are based on reasonable assumptions and results interpretations. Forward-looking statements cannot be relied upon to guarantee Project performance or outcomes and naturally include inherent risk.
This report was amended to include additional clarifying information in October 2023 and November 2023. The basis of the report is unchanged. The changes and their location in the document are summarized in Chapter 2.1.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
1.2 Property Description and Ownership
Sal de Vida (latitude 25° 24’ 33.71” South, longitude 66° 54’ 44.73” West) is located approximately 200 kilometers (km) south of Olaroz in the high-altitude Puna ecoregion of the Altiplano of northwest Argentina at approximately 4,000 meters (m) above sea level. Sal de Vida is within Salar del Hombre Muerto in the Province of Catamarca.
The main route to the Project site is from the city of San Fernando del Valle de Catamarca via National Route 40 to Belen, and Provincial Route 43 through Antofagasta de la Sierra to the Salar del Hombre Muerto. The road is paved all the way to Antofagasta de la Sierra and continues unpaved for the last 145 km to Salar del Hombre Muerto. The Antofagasta region of Chile is used to export lithium carbonate product and to import key chemicals used in the production of lithium carbonate. The property does not have nearby electrical or natural gas access. The Project will be powered by diesel generators with plans to decarbonize through a combination of natural gas supply and renewable solar power options. Environmental and social permits for the solar power options have been approved.
The climate in Sal de Vida area can be described as typical of a continental, cold, high-altitude desert, with resultant scarce vegetation. The climate allows year around project operation.
Allkem’s mining tenement interests in the Sal de Vida Project are held by Galaxy Lithium (Sal de Vida) S.A., a wholly owned subsidiary of Galaxy Resources Ltd. (Australia) which in turn is 100% owned by Allkem Ltd. since August 2021.
Allkem currently has mineral rights over 26,253 hectares (ha) at Salar del Hombre Muerto, which are held under 31 mining concessions. Allkem has been granted easements related to water, camps, infrastructure, and services enabling the commencement of Stage 1 construction. The Project is not subject to any known environmental liabilities other than those actions and remedies indicated in the Environmental Impact Study approval process.
1.3 Geology and Mineralization
Mineral exploration began in the Salar del Hombre Muerto with shallow pit campaigns to obtain data on near-surface geology, subsurface water levels, brine chemistry, and physical parameters. Multiple geophysical campaigns also were completed for subsurface interpretations including gravity, vertical electric soundings, and transient electromagnetic surveys.
Historical drilling was conducted in several phases that were divided into Phases 1 through 6, with Phase 1 commencing in 2009, and Phase 6 East Wellfield development during the period 2020 to 2021. A total of 40 brine well, core, and reverse circulation (RC) drill holes (5,570 m) have been completed. Downhole geophysical logging was completed for the Phase 4 to Phase 6 programs and consisted of resistivity and spontaneous-potential surveys, with three wells having in addition magnetic-resonance, spectral gamma ray, and image logs. Recovery percentages of drill core were recorded for each core hole; percent recovery was excellent for most of the samples obtained.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Porosity samples were collected during 2010, 2011, and 2012 from intact HQ and NQ size cores. In addition to the depth-specific brine samples obtained by drive points during coring, brine samples used to support the reliability of the depth-specific samples included analyses of brine centrifuged from core samples, brine obtained from low-flow sampling of the exploration core holes, brine samples obtained near the end of the pumping tests in the exploration wells, and brine samples obtained during reverse-circulation air drilling.

SEC Technical Report Summary
1.5 Development and Operations
1.5.1 Recovery Methods
Galaxy conducted a series of internal and external test work programs to determine the feasibility of producing battery-grade (BG) lithium carbonate (>99.5 wt% purity) with qualified third parties contracted to perform ongoing validation.
Pilot testing was conducted during 2020 and 2021 purpose-built pilot ponds and pilot plant to validate laboratory test work and explore operational considerations. Testing included empirical evaporation performance, process liming, softening, and crystallization test work. The pilot program demonstrated that consistent production of battery grade lithium carbonate can be produced with the Sal de Vida process. Piloting also allowed the site team to develop experience in evaporation ponds and process plant operation while testing a variety of equipment and instrumentation for the industrial-scale plant.
Project facilities are divided into four main areas including wellfield and brine distribution, evaporation ponds, the lithium carbonate plant, and waste tailings disposal stockpile.
1.5.2 Process Facility Design
The recovery process of lithium from the brine is summarized below and presented in a flowsheet in Figure 1-1.
The process will commence with brine extracted from wells extending to a depth of up to 280 m into the salar. Brine will be pumped to a series of evaporation ponds, where it will be evaporated and processed at the onsite lithium carbonate plant.
The wellfields will be located directly above the Salar del Hombre Muerto over the salt pan, with minimal infrastructure residing on the surface. The brine distribution systems will traverse the salar to where the evaporation ponds will be located. The production plant will be located adjacent to the evaporation ponds on colluvial sediments. The waste disposal areas will surround the evaporation ponds.
The process facility will be located in an area adjacent to the muriate ponds, and will consist of a lithium carbonate plant, with a liming plant and associated plant infrastructure, such as the power station, fueling, and workshops.

Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Detailed engineering is near completion, providing confidence in estimated quantities and engineering schedules.
Allkem’s current operations at the Olaroz project are of similar nature and process. Internal company policies, standard operating procedures, management systems, and structures will allow sufficiently rigid establishment of initial operations at the Project site and reduce commissioning and ramp-up risk.
International equipment fabrication, local supply chains, logistics, site access, contractor equipment and performance, and labor relations represent inherent construction schedule risk which has been modeled using quantitative stochiometric methods to best predict and manage schedule risk.
Mobile equipment will be required for plant and pond operations. Some transport services will be supplied to Allkem under contract with local companies; however, in most cases, the equipment will be owned and operated by Allkem. Allkem will provide fuel and servicing for all vehicles, except for reagent supply and product logistic requirements off-site.
1.5.4 Environmental and Social
Allkem Sal de Vida Stage 1 has all permits and authorizations in place to construct, operate, and produce lithium carbonate from the project. Environmental Impact Assessment (EIA) is renewed every two years. Other permit details can be found in Section 17.6.
The Project construction and operation provide new employment opportunities and investment in the region, which is expected to have a positive social impact.
Allkem Sal de Vida has a Community Relations Plan (CRP) in place, which has specified programs to ensure a sustainable operation within the regional and local communities. The programs set out commitments that include timeframes and schedules where appropriate and are aligned with Galaxy’s four-pillar focus for social initiatives and projects within its sustainability framework, such as education and employment, sustainable development and culture, health and well-being, and infrastructure.
Environmental baseline studies were performed in the Sal de Vida Project area during a number of field seasons starting in 1997. Study areas included water quality evaluations of the salar and surface waters, water chemistry, water baseline studies, flora, fauna, limnology, phytoplankton, archaeology, air quality, noise, soils, geology, geomorphology, hydrogeology, hydrology, climate, landscape, ecosystem characterization, and socioeconomic considerations. Required environmental approvals were obtained prior to the commencement of construction. Further production permitting will be sourced prior to the commencement of operation.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Allkem has developed a Final Closure Plan and associated capital allocation to close the mine at the end of the exploitation permit period. An option to renew the exploitation permit is possible.
The SDV Project permitting processes sufficiently addressed environmental, community, and socio-economic issues allowing the granting of the required permits for construction. Further permitting is progressed to support commencing operations upon completion of construction.
1.6 Mineral Resource Estimate
This sub-section contains forward-looking information related to Mineral Resource estimates for the Sal de Vida Project. The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions outlined in this sub-section including geological and brine grade interpretations, as well as controls and assumptions related to establishing reasonable prospects for economic extraction.
Resource estimation methods to characterize in-situ brine deposits must include two key components: characterization of mineral grade dissolved in the brines, and characterization of the host aquifer drainable porosity that contains the mineral to be estimated. To estimate the total amount of lithium in the brine, the basin was first sectioned into polygons based on the location of exploration drilling, a commonly applied method for lithium brine resource estimates. Each polygon block contained one core drill exploration hole that was analyzed for both depth-specific brine chemistry and drainable porosity. Boundaries between polygon blocks were generally equidistant from the core drill holes and the total well depth was used as the base of the polygons. The total area of polygon blocks used for resource estimates is about 160.9 square kilometers (km2). Within each polygon shown on the surface, the subsurface lithological column was separated into lithologic units. Each interval was assigned a specific thickness and was given a value for drainable porosity and average lithium content based on laboratory analyses of samples collected during exploration drilling. The estimated resource for each polygon was the sum of the products of saturated lithologic unit thickness, polygon area, drainable porosity, and lithium content. The resource estimated for each polygon was independent of adjacent polygons.
The key parameters of brine mineral grade and drainable porosity were analyzed and used to estimate the Measured, Indicated, and Inferred Brine Resources. To classify a polygon as Measured or Indicated, the following factors were considered:
● | Level of understanding and reliability of the basin stratigraphy. |
● | Level of understanding of the local hydrogeologic characteristics of the aquifer system. |
● | Density of drilling and testing in the salar and general uniformity of results within an area. |
● | Available pumping test and historical production information. |
Based on the current understanding of the hydrogeological system of the Salar de Hombre Muerto, the additional data on brine occurrence and chemistry, the relative consistency of the hydrogeological and chemical data, confidence in the drilling and sampling results achieved to date, and historical production information (east side), there were sufficient grounds to classify certain polygons as Measured Brine Resources.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Table 1-1 presents the Mineral Resources exclusive of Mineral Reserves (Chapter 12). When calculating Mineral Resources exclusive of Mineral Reserves, a direct correlation was assumed between Measured Resources and Proven Reserves as well as Indicated Resources and Probable Reserves. Mineral Resources were estimated on an in-situ basis; Reserves at a point of reference of brine pumped from the wellheads to the evaporation ponds were subtracted from the Resources inclusive of Reserves. A lithium cut-off grade of 300 mg/l was utilized based on a breakeven cut-off grade for a projected lithium carbonate equivalent price of US$20,000 per tonne over the entirety of the LOM and a grade-tonnage curve. Considering the economic value of the brine against production costs, the applied cut-off grade for the resource estimate (300 mg/l) is believed to be conservative in terms of the overall estimated resource. Intervals of the polygons with grades below the 300 mg/l cut-off grade were not considered in the resource estimate; thus, with these assumptions, a reasonable basis has been established for the prospects of eventual economic extraction.

Factors that may affect the Brine Resource estimate include: locations of aquifer boundaries; lateral continuity of key aquifer zones; presence of fresh and brackish water which have the potential to dilute the brine in the wellfield area; the uniformity of aquifer parameters within specific aquifer units; commodity price assumptions; changes to hydrogeological, metallurgical recovery, and extraction assumptions; density assignments; and input factors used to assess reasonable prospects for eventual economic extraction. Currently, the QPs do not know of any environmental, legal, title, taxation, socio-economic, marketing, political, or other factors that would materially affect the current Resource estimate.
1.7 Mineral Reserve Estimate
This sub-section contains forward-looking information related to Mineral Reserve estimates for the Sal de Vida Project. The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions set forth in this sub-section.
The Mineral Reserve was estimated based on physical pumping of the brine that flows during wellfield pumping using a calibrated numerical model that simulates groundwater flow and solute transport. The method considers modifying factors for converting Mineral Resources to Mineral Reserves in brine deposits, including allowable well field pumping and dilution of brine during pumping, among others.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
A 3D numerical model was constructed using the Groundwater Vistas Version 7 interface and Modflow USG-Transport was utilized to simulate variable-density flow and transport. The active model domain encompasses the clastic sediments and evaporite deposits that comprise the Salar del Hombre Muerto as well as the upgradient alluvial deposits and the Río de los Patos sub-basin. Vertically, the domain was divided into 12 model layers, and the base of the active model domain was set based on the current depth to basement interpretation. The numerical model boundary conditions were designed to be consistent with the conceptual baseline water balance and hydraulic properties were assigned based on the hydrogeological unit and adjusted throughout the calibration process.
Prior to the simulation of future brine production, the numerical model was calibrated to verify assigned model parameters such as hydraulic conductivity and specific storage. The numerical groundwater model was initially calibrated to average, steady-state conditions using the available average on-site field measurements of water levels in observation wells. A transient model calibration to two long-term pumping tests in the East and Southwest Wellfields was conducted to better represent the aquifer’s response to pumping. Furthermore, a model verification period was analyzed with respect to real extracted lithium grades. Total dissolved solids (TDS) in the brine and freshwater were defined as the only solute components in the numerical model to represent the concentration–water density relationship and freshwater–brine interface. The linear relationships with TDS were used to estimate concentrations in pumped brine from the wellfield simulation due to its good correlation with water density.
Projected production locations were based on the Measured Resource zones and were configured to reduce well interference during pumping. The Stage 1 pumping from the East Wellfield is expected to produce 15,000 t of LCE per year (assuming processing losses) while Stage 1 and Stage 2 will generate a total of 45,000 t of LCE per year (assuming processing losses), with active pumping from the southwest and eastern portions of the mine concessions. Due to seasonal changes in pond evaporation and maintaining the lithium carbonate target for each stage, the modeled production pumping rates are time-variable on monthly and annual timeframes.
The total lithium to be extracted from the proposed East and Stage 2 Expansion Wellfields was calculated for a total period of 40 years. The model projections used to determine the Brine Reserve, which assumed increasing pumping from both wellfields, indicate that the proposed wellfields should be able to produce a reliable quantity of brine at an average annual rate of approximately 315 l/s in the case of production wells in the eastern portion of the mining concessions and about 191 l/s in the case of the southwest.
Table 1-3 gives results of the Proven and Probable Brine Reserves at the point of reference of brine pumped to the evaporation ponds. A lithium cut-off grade of 300 mg/l was conservatively utilized based on a breakeven cut-off grade for a projected lithium carbonate equivalent price of US$20,000 per tonne over the entirety of the LOM. The average lithium grade of the Proven and Probable Reserves corresponds to 757 mg/l and represents the flux-weighted composite brine collected as brine is routed to the evaporation ponds. Extracted grades at individual production wells and the average Proven and Probable reserve concentration are well above the 300 mg/l cut-off grade, demonstrating that production is economically viable.

During the evaporation and concentration process of the brine, there will be anticipated losses of lithium. Based on the Chapter 10 breakdown of recoveries and current processing method, the amount of recoverable lithium in the evaporation ponds and plant is calculated to be 70% of the total brine pumped to the ponds. This applies to the current processing method which may be subject to improvements at a later date.
The Mineral Reserve was classified according to industry standards for brine projects, as well as the confidence of the numerical model predictions and potential factors that could affect the estimation. Projected production wells were placed in Measured Resource areas. The Qualified Persons (QPs) believe that the Proven and Probable Mineral Reserves were adequately categorized, as described below:
● | Proven Reserves were specified for the first 7 years of operation (years 1-7) in the East Wellfield (Stage 1) and years 3-9 for the Stage 2 Expansion Wellfield given that short-term results have higher confidence due to the current model calibration and also the initial portion of the projected LOM has higher confidence due to less expected short-term changes in extraction, water balance components, and hydraulic parameters. |
● | Probable Reserves were conservatively assigned after 7 years of operation (years 8-40 in the East Wellfield and years 10-40 for the Stage 2 Expansion Wellfield because the numerical model will be recalibrated and improved in the future due to potential changes in neighboring extraction, water balance components, and hydraulic parameters. |
Regarding risk factors, the Brine Reserve estimate may be affected by the following:
● | Assumptions regarding aquifer parameters and total dissolved solids used in the groundwater model for areas where empirical data does not exist. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Estimated vertical hydraulic conductivity values partially control the amount of anticipated future dilution in areas where fresh water overlies brine. |
Regardless of these sources of uncertainty, each phase of the Project was conducted in a logical manner, and results were supportable using standard analytical methodologies. In addition, calibration of the numerical model against long-term pumping tests provides solid support for the conceptual hydrogeologic model developed for the Project. Thus, there is a reasonably high-level confidence in the ability of the aquifer system to yield the quantities and grade of brine estimated as Proven and Probable Mineral Reserves. To the extent known by the QPs, there are no known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors that could affect the Mineral Reserve estimate which are not discussed in this Report.

1.10 Additional Information – Stage 2 Expansion
1.10.1 Stage 2 Description and Layout
The Technical report focusses on the current Sal de Vida Stage 1 execution followed by a planned modular Stage 2 expansion.
The Sal de Vida lithium carbonate plants were designed to produce 15,000 tpa of lithium carbonate in Stage 1, with Stage 2 enabling the production of an additional 30,000 tpa through two 15,000 tpa modules. The modular plant design was based on average brine supplies of 26 m3/h for Stage 1 and an additional 52 m3/hr for stage 2 respectively. The design includes an average lithium concentration of 21 g/l in the softening feed. Plants will operate continuously with a design availability of 91%.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Stage 2 will consist of further expansion of operations as established in Stage 1. All Stage 2 facilities will be located within the Stage 1 Project tenements in the southern sector of the Salar del Hombre Muerto. The wellfield will be located directly above the western sub-basin of the Salar del Hombre Muerto over the salt pan. The brine distribution will traverse the salar southeast towards the evaporation ponds on the alluvial field. The production plant for Stage 2 will be sited adjacent to the production plant for Stage 1. The waste disposal areas will surround the evaporation ponds.
A layout of the Stage 2 expansion as depicted in Figure 1-4.
1.10.2 Stage 2 Infrastructure
Utilities and support infrastructure will be expanded in a modularized fashion as necessary to support Stage 2.
Given that Stage 2 is a planned expansion of SDV Stage 1, certain infrastructures such as roads and camp will either remain the same or experience incremental changes (i.e., an extra tank, genset, or another module). This section includes a description of the main infrastructure located at site, including the facilities outlined in Table 1-8.

1.10.3 Stage 2 Permitting
The physical, biological, and social baseline data for the Project has been collected over the wider area of the Salar de Hombre Muerto since 2011 (ERM, 2011). Specific baseline field campaigns and environmental impact studies will need to be performed as part of the environmental permitting for Stage 2 of the Project. The Stage 2 baseline field campaigns have not commenced as yet.
The Environmental Impact Declaration (DIA) approved in December 2021 was for Stage 1 only. The Stage 2 will require an amendment to the Stage 1 DIA with separate investigations related to the Stage 2 affected areas. The Stage 2 DIA application has not commenced as yet. Further study and basic engineering are required to further define the Stage 2 affected areas and related impacts.
The Sal de Vida Project will require 100-120 m3/hr of raw water for the operation of Stage 1 and 2. The water permits that will be required to take account of the increased water demand to construct and operate Stage 2 have not been applied for yet.
It is estimated that required engineering definition, studies, and permitting application processing will require approximately 18 months based on timelines experienced with Stage 1.

1.10.4 Stage 2 Capex and Opex
The capital cost estimate for Stage 2 of the Sal de Vida Project was prepared by Allkem based on previously completed studies by Worley Chile S.A. and Worley Argentina S.A. (Collectively, Worley) in collaboration with Allkem. Allkem supplemented previous study estimates with actual construction cost data obtained from the ongoing Sal de Vida Stage 1 construction. The estimate is a Class 4 AACCE with an expected accuracy of +30% / - 20%. The costs are based on Q2 2023 pricing and reflective of the Effective Date.
Capital Cost Estimation for Stage 2 was based on the Sal de Vida Stage 1 AACE class 2 estimate currently in execution. The modularized nature of the project expansion allows for direct cost comparisons from Stage 1 to Stage 2, supplemented by escalation estimation and appropriate contingency.

1.10.6 Stage 2 Risk Management
A Risk Assessment process was conducted in 2021 (Spark, 2021) which identified a broad spectrum of hazards that provides a reasonable representation of the current risk profile for the Stage 2 expansion project. The overall risk profile is currently driven by Project Delivery, and Financial/Operational Performance risks, which is to be expected of this project at the Pre-feasibility stage. While it is clear there is still considerable risk management work to be undertaken through the development of the Sal de Vida Project, there are no current identified risk issues that are considered insurmountable or that will prevent the Stage 2 expansion from proceeding into execution.
1.10.7 Stage 2 Conclusions and Recommendations
The planned Sal de Vida Stage 2 expansion has been studied at a pre-feasibility study level. The process pond infrastructure, process plant design, and support service infrastructure are deemed of suitable design and sufficiently quantified to support the level of study. The accuracy of cost information gained from ongoing Stage 1 execution is deemed sufficiently accurate for the level of study.

After completing any required value engineering, finalizing technology tradeoffs and selections, and advancing engineering design, the permitting process should commence in parallel with further engineering design. Progression of the Stage 1 execution must be monitored, and lessons learned incorporated into the Stage 2 project. Ongoing risk management and reviews are recommended to ensure currency of risk management activities. Social engagement processes and programs can be amended as needed to include for the future Stage 2 expansion.
1.11 Project Risks and Opportunities – Stages 1 and 2
1.11.1 Risks
A Project risk workshop was held in February 2020 and was subsequently updated in a risk assessment process conducted on March 21, 2021, prior to Stage 1 construction commencement. Ongoing risk reviews and mitigating action progress occur periodically. The current risk register is deemed current as of the Effective Date.
The workshops identified a broad spectrum of hazards which provides a reasonable representation of the current Project risk profile, with a focus on the initial stage of the Project. The overall risk profile is currently driven by Project delivery, and financial/ operational performance issues, which is to be expected of a brine project at the feasibility and early execution stage. This is consistent with the Project management team’s expectations for a feasibility-stage study, given the industry’s history with medium-sized project delivery, and the inherent uncertainty as to how a number of key risks in these areas can to be managed.
The Sal de Vida Project identified areas of focus in the Project risk register. The key risks to Project viability can be summarized as:
● | Allkem activities fail to meet health, safety, environmental, community (HSEC) or CSR expectations. |
● | Loss of community support for the Project. |
● | Project capital cost increases significantly (e.g., productivity, incomplete engineering, poor estimation, Project delays, poor Project controls, changing market conditions). |
● | Plant unable to achieve name plate production within expected timeframes. |
● | Plant fails to achieve the production metrics (e.g., throughput, utilization, recovery, product quality). |
● | Changes to the Argentinian financial/regulatory framework (e.g., taxation, new legislation, import/ exports, inflation). |
● | Increased complexity of the design (BG, automation, late changes to the design) impacting the rate of engineering, procurement of long leads, commissioning etc. |
● | Performance of selected contractors (schedule, cost, quality, remote operations). |
● | COVID-19 or similar global issues impacting the Project (cost, schedule, outbreak on site). |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Ability to meet all required stakeholder conditions (e.g., local employment, environmental). |
The existing risk controls and those implemented during the implementation/operations phases are broadly defined in the relevant risk register and will be enhanced as the register is revisited throughout the Project delivery phase and into the operational phase. These controls are predicted to be appropriate for further risk reduction; however, ongoing effort will be required to ensure the delivery of all required controls to achieve acceptable risk levels within the Project, and that these risks are well-understood. This risk/reward evaluation will need to be reviewed at each key Project stage.
1.11.2 Opportunities
Strategically, the two staged modular approach allows prudent de-risking of the Project’s development, by adopting experience from Stage 1 into later stages and limiting upfront capital expenditure. It is expected that Stage 2 will not commit significant funds until the previous stage production is proven. Additionally, it is expected that Stage 2 delivery costs from the continuity of people, systems, and processes, engineering efficiencies, and targeted allocation of contingency may provide an upside. The PFS level does not accommodate these synergies, but they are expected as engineering advances.
The estimated Brine Resources and Brine Reserves summarized in this Report may have upside potential for tonnage increases, based on results from the ongoing production well drilling, and aquifer testing of the recently constructed Eastern wellfield production wells.
A large portion of the resource remains as Indicated. Further drilling campaigns and sampling will enhance aquifer understanding and could result in Brine Resource confidence category upgrades.
Further deeper drilling could indicate further depth potential of the resource. These deeper drill holes have upside potential to extend the limit of the Brine Resource estimates at depth.
The Brine Resources are reported above a 300 mg/l Li cut-off. Many of the brine-based lithium companies in the industry use a 200 mg/l Li cut-off. Should Allkem elect to lower the cut-off, there is potential for additional lithium carbonate content to be estimated as part of the Brine Resources. Changing the cut-off grade will have no impact on the Brine Reserve because all the production wells associated with the Brine Reserve are being designed to avoid capturing this lower lithium-grade brackish water. If the Project continues past the current projected 40-year mine life, lower- grade brine and brackish water have potential to be economic in the future.

SEC Technical Report Summary
1.12 Conclusions and QP Recommendations – Stages 1 and 2
The Sal de Vida project hosts a yet undefined lithium resource with a defined reserve that supports both Stages 1 and 2 of the Project. Additional exploration is likely to define additional resources or upgrade the resource classification. The collected data and models are deemed reliable and adequate to support the Mineral Resource estimate, cost estimates and the indicated level of study for both Stages 1 and 2.
The described processing and service infrastructure is deemed adequately sized to meet the designed Stage lithium carbonate production rates with inherent risks remaining as described. Support service infrastructure is adequately sized to support Stage 1 with additional expansions required for Stage 2 at that time.
Social, environmental, and government aspects are deemed sufficiently addressed and resulted in the progression of the Stage 1 permitting for construction. Further and ongoing monitoring and actions will be required to maintain and progress the renewal of permitting.
Under the assumptions described in this Report, the Project shows feasible economic extraction for both described Stages at the indicated study level.
1.12.1 Recommendations
1.12.1.1 Exploration
Further exploration should be conducted to better identify and potentially demonstrate additional extractable brine in other parts of the basin. Further geophysical surveys (gravity and magnetic), core drilling deeper than 300 m, downhole sampling of any additional wells, and additional 30-day pumping tests can contribute to expanding the reserve.
1.12.1.2 Resource Estimate
It is recommended that a resource block model be created instead of the polygon method to estimate the lithium brine resource. New brine sample results from pumping and production wells should be incorporated.
Based on newly obtained field data the resource estimate should be updated. The categorization should also be reviewed based on newly obtained information.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
1.12.1.3 Reserve Estimate
The numerical model should be updated in the short to medium term to simulate lithium in addition to total dissolved solids. The simulation of total dissolved solids is necessary to properly simulate density-driven flow due to its good correlation to water density.
A review of the numerical model should be completed when further information from recommended field work is available, and the grid should be further refined in areas of the projected production wells. The deeper portions of the numerical model should be updated with improved information on the brines at depth, including the hydraulic conductivity and storage zones.
1.12.1.4 Permits
Ongoing monitoring and reporting requirements must continue to ensure compliance with permitting conditions. Frequent and periodic collection of streamflow measurements, rainfall, run-off, and shallow groundwater data can be used to improve representations in the numerical water balance and other basin models.
SDV Stage 2 requires separate environmental impact and permitting assessments. Following sufficient engineering progress, proactive application for further freshwater extraction, environmental assessments, and development permits for Stage 2 must progress to avoid delays.
1.12.1.5 Further Studies
Further environmental and engineering studies have been identified to progress the Project:
● | Investigate water reuse technology and other technologies that will allow reduction of the carbon footprint. |
● | Emphasize scaling the capacity of the Solar Plant to produce clean energy for Stage 2 maximizing production and project benefits. |
● | Proceed with FEED and Detailed engineering of Stage 2. |
● | Complete further decarbonatization energy trade-off studies considering renewable power from a photovoltaic farm and potential connection to a regional natural gas pipeline located 20 km from the Project. |
● | Continue with geotechnical investigations to confirm ground suitability Stage 2 infrastructure. |

2.5 Specific Characteristics of Lithium Brine Projects
Although extensive exploration and development of new lithium brine projects has been underway for the last decade it is important to note there are essential differences between brine extraction and hard rock lithium, base, or precious metal mining. Brine is a fluid hosted in an aquifer and thus can flow and mix with adjacent fluids once pumping of the brine commences. An initial in-situ resource estimate is based on knowledge of the geometry of the aquifer, and the variations in porosity and brine grade within the aquifer.
Brine deposits are exploited by pumping the brine to the surface and extracting the lithium in a specialist production plant, generally following brine concentration through solar evaporation in large evaporation ponds. To assess the recoverable reserve, further information on the permeability and flow regime in the aquifer and the surrounding area is necessary to be able to predict how the lithium contained in brine will change over the Olaroz Project life. These considerations are examined more fully in Houston et. al., (2011) and in the Canadian Institute of Mining (CIM) and Joint Ore Reserve Committee (JORC) (Australia) brine reporting guidelines. The reader is referred to these key publications for further explanation of the details of brine deposits.

Sal de Vida Lithium Brine Project
SEC Technical Report Summary
3.2.1 Mining Title
The basic statute that governs mining activity in Argentina is the National Mining Code, National Law 1919 (AMC). The Argentinean Constitution recognizes the provincial or federal original ownership of the minerals located within their jurisdictions and the AMC establishes a non-discretionary system under which mining rights are awarded to private entities and/or individuals, which are equivalent in rights to private ownership and constitutes a complete and different property of the land of which its underlays. Regardless the state of nature of the mineral (solid, liquid, or gaseous), the AMC considers three categories of mines, being the lithium classified as a metalliferous substance included in the first category of mines. The AMC recognizes the private entities right to explore and develop deposits and freely dispose of the minerals extracted within the area of the concession, as well as the right to transfer such rights without any previous government discretional approval. These regulations create the legal framework that governs the relationship between the government and miner (through an exploration permit or a mining concession), and between the miner and third parties.
Key parameters of the AMC include:
● | Mining properties form a different property from the surface ownership where they are located (either regarding fiscal or private land). |
● | Any individual or legal entity with capacity to legally purchase and own a real estate property may petition and own a mining right. |
● | The original ownership of a mining right is acquired through a legal concession granted for limited (in case of an exploration permit) or unlimited (in case of an exploitation concession) time and only subject to the compliance of certain maintenance conditions as set by the AMC. |
● | There is provincial jurisdiction regarding mining police, administrative authority and in environmental matters. |
The AMC governs the rights, obligations, and procedures referring to the exploration, exploitation, and use of mineral substances.
There are two main mining rights that can be awarded under the AMC:
● | Exploration permits (“cateo”): cateos grant the applicant an exclusive right to explore a specific area (maximum 10,000 ha) for a certain period (maximum 1,500 days). No exploitation can be undertaken, but any exploratory method is acceptable as long as the method is consistent with a previously approved Environmental Impact Study. |
● | Exploitation concessions (from “manifestacion de descubrimiento” to “mina”): exploitation concessions are acquired by means of a “legal concession” granted by the Mining authority (Mining Authority) under the provisions of the AMC. The exploitation concession has no time limit. There are different ways of acquiring an exploitation concession: |
o | By discovering minerals as a consequence of exploration activity within a cateo. |
o | When minerals are discovered by accident; that is, without a cateo (e.g., the area is free of previous exploration permits) or exploitation concessions. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
o | When an exploitation right has been declared and registered by the Mining Authority as “vacant” due to a non-compliance with the requirements settled by law by a third party. |
The discoverer must also indicate an area which does not exceed twice the maximum possible extension of an exploitation concession, within which the exploration works will be conducted, and mining claims (“pertenencias”) will be confined to. This area includes the discovery site and would remain unavailable until a survey is duly approved and authorized. When filing an application, it is customary to refer to the exploration permit within which the discovery is located, so that any overlap with existing rights is already anticipated. Any area of land within which boundaries the holder of a mining concession is allowed to conduct exploration and or exploitation works is called a “claim”. Each claim of a lithium or borates deposit is 100 ha. The exploitation concessions do not expire but are subject to the fulfilment of certain specific conditions or obligations known as “amparo minero”. This includes payment of a mining fee, and completion of an investment plan:
● | Mining fee (canon): the AMC requires a titleholder to pay an annual fee per claim, which is periodically fixed as required by federal law. If the payment is not made within 2 months of the claim expiration date, the concession is terminated ipso facto. In the case of lithium claims, the AMC was amended by Nacional Law 27,701 in Sections 213 and 215, the fee is updated in accordance with an annual resolution issued by the Secretary of Mining, based on the price increase index. Currently AR$8,000 as of Effective Date. |
● | Investment plan: within 1 year from the date of request of the legal survey (irrespective of the mining property being surveyed or not), the applicant/concessionaire must submit to the Mining Authority an estimate of a 5-year plan and amount of capital investment that it intends to perform in connection with: |
o | The execution of mining works. |
o | The construction of camps, buildings, roads, and other related works. |
o | The acquisition of machinery, stations, parts, and equipment, indicating its production or treatment capacity. |
In accordance with the provisions of Article 217 of the AMC, the investment for a mining property cannot be less than 300 times the annual fee that corresponds to such mining property, based on its category and the number of claims, provided that such investment is fully completed within five years from its filing. An amount not lower than 20% of the estimated aggregate amount must be invested in each of the first two years.
A sworn statement on the compliance status of the investments must be submitted to the Mining Authority within three months of the expiration of each annual period.
The Mining Authority in each Province has the ability to:
● | Enact the Mining Procedure Code (for example, Provincial Law No. 5682 in Catamarca Province), which must follow AMC guidelines. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Award mining rights and control its compliance in accordance with the AMC and applicable Procedure Code provisions. |
Although each Mining Authority awards and controls the mining rights within its territory, in practice the Mining Authority must strictly follow AMC guidelines, as every procedural step is clearly detailed in the AMC.
3.2.2 Surface Rights
The AMC sets out rules under which surface rights and easements can be granted for a mining operation, and covers aspects including land occupation, rights-of-way, access routes, transport routes, rail lines, water usage and any other infrastructure needed for operations.
For private property, compensation must be paid to the affected landowner in proportion to the amount of damage or inconvenience incurred; however, no provisions or regulations have been enacted as to the nature or amount of the compensation payment.
For instances where no agreement can be reached with the landowner, the Mining Authority and/or the competent court pursuant to the applicable procedure shall resolve the conflict.
For fiscal property (national or provincial ownership) the AMC rule that the surface rights and easements should be granted for a mining operation without compensation.
The AMC provides the mining right holder with the right to expropriate at least the required property up to a maximum of one claim.
3.2.3 Water Rights
Typically, Provincial water authorities:
● | Issue water usage permits, including usage purpose, amount of water required, how the water is to be delivered to the end-user, and any infrastructure requirements. |
● | Establish a priority system for the permits, based on the type of water consumption. |
● | Govern the duration of issued permits. |
● | Levy usage fees based on the amount of water consumed/used. |
Water use rights may be acquired by permit, by concession, and, under laws enacted in some Provinces, through authorization. Revocable permits for water use can be granted for a specific purpose. A grant (concession) is typically awarded for a time period that is based on the intended use; however, some permits concessions can be granted in perpetuity.

3.2.4 Fraser Institute Policy Perception Index
The QPs used the Investment Attractiveness Index from the 2020 Fraser Institute Annual Survey of Mining Companies report (the Fraser Institute survey) as a credible source for the assessment of the overall political risk facing an exploration or mining project in the Province of Catamarca, Argentina.
The QPs used the Fraser Institute survey because it is globally regarded as an independent report-card style assessment to governments on how attractive their policies are from the point of view of an exploration manager or mining company senior management and forms a proxy for the assessment by the mining industry of the political risk in the Province of Catamarca, Argentina. In 2020, the rankings were from the most attractive (1) to the least attractive jurisdiction (77), of the 77 jurisdictions included in the survey.
The Province of Catamarca, Argentina ranked 44 out of 77 jurisdictions in the attractiveness index survey in 2020, 45 out of 77 in the policy perception index, and 44 out of 77 in the best practices mineral potential index.
3.3 Ownership
All of Allkem’s mining tenement interests in the Sal de Vida Project are held by Galaxy Lithium (Sal de Vida) S.A., which is a wholly owned subsidiary of Galaxy Resources Ltd. (Australia) which is owned by Allkem Ltd., as shown in Figure 3-3.

3.7 Third-Party Rights
All the mining concessions for the Sal de Vida Project were secured under purchasing agreements with pre-existing owners and claimants. In some cases, sellers retained usufruct rights (a legal right accorded to a person or party that confers the temporary right to use and derive income or benefit from someone else’s mining property) and commercial rights (third-party rights) for the development of ulexite (borates) at surface (Table 3-2).
The transfer deeds establish that the lithium property holder, Allkem, has priority over these rights. Allkem has retained the option to buy out any of these rights if it considers it necessary at any point in time.

3.8 Mining Royalties
Pursuant to Law 4757 (as amended), Catamarca Mining royalty is limited to 3% of the mine head value of the extracted ore, which consist in the sales price less direct cash costs related to exploitation (excluding fixed asset depreciation, the “Mining Royalty”).
On December 20, 2021, GLSSA and the Governor of the Province of Catamarca subscribed a Royalties Commitment Deed (the “Royalty Agreement”), pursuant to which GLSSA agrees to pay to the Province of Catamarca a maximum amount of 3.5% of the “net monthly revenue” from the Project, as follows:
● | The “Mining Royalty” will be paid as indicated by the provincial Royalty Regime. |
● | An “Additional Contribution” of 3.2% less the Mining Royalty and the applicable water cannon. |
● | 0.3% shall be paid as a “CSR Contribution”. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The validity of the Royalty Agreement is subject to the approval of the Legislature of the Province of Catamarca, which is in due course to be obtained.
The payment of Mining Royalty is due once the commercial production of the Sal de Vida Project commences, and the payment of the Additional Contribution and CSR Contribution is due once the Province of Catamarca (through the relevant authority) grants GLSSA the relevant water concession pursuant to Section 7 of the Water Law No. 2577, as amended.
The Additional Contribution and CSR Contribution will be paid through a Trust, pursuant to provincial legislation to be enacted.
The 3.5% maximum amount shall be the maximum amount payable by GLSSA to the province of Catamarca, for any reason whatsoever, for the whole life of the Project (including any expansions).
The “net monthly revenue” will be calculated by reference to the amounts invoiced by GLSSA each month for the sale of lithium products produced from the Project, and for the Mining Royalty, less (i) any taxes, duties, levies included on those invoiced amounts and (ii) any sales reimbursement.
The Additional Contribution made to the Trust shall be used exclusively for conducting investment projects, infrastructure works, and productive development within the area where the Project is located and, specifically, within the direct (Department of Antofagasta) and indirect (Department of Belén and Santa María) zones of influence of the Project.
The CSR Contribution shall be used exclusively for conducting investment projects, infrastructure works and productive development within the site area where Project is located and, specifically, within the direct zone of influence (Department of Antofagasta).
3.9 Permitting Considerations
Permitting considerations are discussed in Chapter 17 – Environmental Studies, Permitting, Social or Community Impacts.
3.10 Environmental Considerations
The Project is not subject to any known environmental liabilities. There has been active ulexite mining within the boundaries of the existing land agreement, but the operations are limited to within 5 m of the surface and will reclaim naturally fairly quickly. All ulexite activities are dormant in the area as a result of the low ulexite prices and there is no indication of reactivation.
Environmental considerations are discussed in Chapter 17 – Environmental Studies, Permitting, Social or Community Impacts.

3.11 Social License Considerations
Social considerations are discussed in Chapter 17 – Environmental Studies, Permitting, Social or Community Impacts.
3.12 Conclusion
Legal opinion provided supports that Allkem currently holds an indirect 100% interest in the Sal de Vida Project through its subsidiary Galaxy Lithium (Sal de Vida) S.A.
Legal opinion provided supports that the mineral tenures held are valid and sufficient to support declaration of Brine Resources and Brine Reserves.
The AMC sets out rules under which surface rights and easements can be granted for a mining operation. In instances where no agreement can be reached with the landowner, the AMC provides the mining right holder with the right to expropriate the required property up to a limited minimum surface. Water use rights may be acquired by temporary permits, by permanent concessions, and, under laws enacted in some Provinces, through authorization.
Allkem currently has approved water permits; see Section 17.5.3.
A number of the mining concessions are subject to usufruct rights for ulexite.
Social and permitting applications have sufficiently progressed to permit the commencement of Stage 1 construction. The employees of Montgomery & Associates are not aware of any significant environmental, social, or permitting issues that would prevent future exploitation of the Sal de Vida Project, other than as discussed in this Report.

4. Accessibility, Climate, Physiography, Local Resources, and Infrastructure
This section summarizes the accessibility, climate, physiography, local resources, and infrastructure for the Project.
4.1 Physiography
The Project is located in a flat plain at an altitude of about 4,000 m above land surface. Vegetation in the Puna is sparse, reflecting the high-altitude desert environment, and consists of low woody herbs, grasses, and cushion plants. There is no vegetation on the salar.
Two major perennial streams feed the salar from the south, the Río de los Patos and the Río Trapiche. The Río de los Patos drains about 79% of the total salar catchment area, and the Rio Trapiche drains approximately 8%.
There are no protected area or natural reserves in the Sal de Vida Project area. Within the baseline environmental study area there are two reserves, Los Andes Reserve in the Province of Salta, and the Laguna Blanca Biosphere Reserve in the Province of Catamarca. The Sal de Vida Project is 75 km south of the Los Andes Reserve and 35 km north of the Laguna Blanca protected area.
4.2 Accessibility
The main route to the Project site is from the city of Catamarca via national Route 40 to Belen, and provincial Route 43 through Antofagasta de la Sierra to Salar del Hombre Muerto. The road is paved all the way to Antofagasta de la Sierra and continues unpaved for the last 145 km to Salar del Hombre Muerto. This road is well maintained and serves Livent Corporation’s Fenix lithium operations, Galan Lithium Ltd.’s Hombre Muerto Project and Allkem’s Sal de Vida Project.
The shortest route to the Project site is from Salta via San Antonio de los Cobres. The access road is paved for the first 75 km to San Antonio de los Cobres and continues unpaved for 215 km to Salar del Hombre Muerto. The total distance between the city of Salta and the Sal de Vida Project is 390 km. Provincial Route 51 is a well-maintained road and is used by a number of mining projects. The drive time is approximately 6 hours in a four-wheel drive vehicle or 10 hr by heavy vehicle or bus.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
4.3 Climate
The Project is located in the Puna ecoregion of the Altiplano, where the climate is extremely cold and dry. The warmest months are January and February, with average temperatures of 11.6°C and 10.9°C respectively. The coolest month is July, with an average temperature of 1.6°C.
Solar radiation is intense, especially during the summer months of October through March, leading to high evaporation rates. Average annual evaporation in the Salar de Hombre Muerto is estimated at 2,710 millimeters (mm).
Rainfall is generally restricted to the summer months (December to March). Based on weather data collected in 2001, the annual precipitation from 1992 to 2001 averaged 77.4 mm.
The area is extremely windy; wind speeds of up to 80 km/hour have been recorded during the dry season.
Operations are planned to be conducted year-round.
4.4 Local Resources and Infrastructure
The nearest villages are Antofagasta de la Sierra in the Province of Catamarca, 145 km south of the Project site, and San Antonio de los Cobres in the Province of Salta, 210 km north of the Project site. Antofagasta de la Sierra has an estimated population of 1,200 people and the village has basic services. San Antonio de los Cobres has an estimated population of 5,000 inhabitants with greater services including medical facilities, border patrol (Gendarmería Nacional), and schools.
The closest powerline, a 330-kVA line, is located 140 km north of the Sal de Vida Project, oriented southeast–northwest, and supplies power to Chile. Based on the distance to the Sal de Vida Project and the estimated capital requirements for accessing this network in the 2021 Feasibility Study, Allkem assumed that site-generated power is the preferred option.
The Argentine train network is well established and connects the major cities and ports. However, the system is currently not fully functional, and many lines are derelict. The Ferrocarril Belgrano line is located 100 km to the north of the Salar del Hombre Muerto. It consists of a narrow-gauge railway connecting with the Chilean railway network Ferronor to reach the Pacific Ocean. Livent reinstated the Pocitos–Antofagasta link which is used to ship product and import reagents. The Chilean section regularly services the Escondida and Zaldivar mines. A public airstrip is located in Antofagasta de La Sierra and a private airstrip is located at Livent’s Salar del Hombre Muerto operations.
International cargo for Sal de Vida could use a combination of ports in the Buenos Aires region of Argentina and the Antofagasta region of Chile. The Ports of Antofagasta and Angamos consist of deep-water port facilities serving the mining industry in northern Chile. The Port of Antofagasta is an inbound port and could be used by Allkem to import 50% of the soda ash requirements. The Port of Angamos is an outbound port and could be used by Allkem to export lithium carbonate via the Pacific Ocean. The Ports of Rosario, Campana and Buenos Aires consist of large port facilities serving multiple industries in Argentina’s main economic hubs.

SEC Technical Report Summary
Additional information on infrastructure that may be available to the Project, and which will be required for Project operations, is provided in Chapter 15 – Infrastructure.
4.5 Conclusion
Any future mining operations are expected to be operated year-round.
There is sufficient suitable land available within the mineral tenure held by Allkem for infrastructure such as waste disposal, process plant, and related mine facilities.
A review of the existing power and water sources, manpower availability, and transport options indicates that there are reasonable expectations that sufficient labor and infrastructure will be available to support exploration activities and any future mine development.

SEC Technical Report Summary
6. Geological Setting, Mineralization and Deposit
This section summarizes the deposit and geological setting of the Project.
6.1 Regional Geology
The regional geological setting is Altiplano Puna plateau, an area of uplift that began during the middle to late Miocene (10 – 15 Ma). Red-bed sediments formed during the early to middle Miocene in areas of structural depressions. During the middle to late Miocene, a combination of thrust faulting, uplift and volcanism led to the sedimentary basins becoming isolated. The Cordilleras and major watersheds bound the Puna area to the west and east. Sedimentation in these basins began with the formation of alluvial fans at the feet of the uplifted ranges and continued with the development of playa sandflats and mudflat facies.
In basin areas, the watersheds are within the basins; there are no outlets from the basins. Ongoing runoff, both surface and underground, continued solute dissolution from the basins and concentration in their centers where evaporation is the only outlet. Evaporite minerals occur both as disseminations within clastic sequence and as discrete beds.
6.2 Local & Property Geology
The lithologies in the Project area are summarized in Table 6-1 and showing in Figure 6-1.
Table 6-1 – Lithology Table.

6.3 | Deposit Description |
6.3.1 | Introduction |
Playa (salar) basins typically have closed topography and all drainage trends towards the interior of the basin. Generally, no significant groundwater discharges from these basins. Most groundwater exits from the aquifer naturally by evapotranspiration, which is a combination of direct evaporation and transpiration from vegetation. Surface waters that flow into the basin are either directly evaporated or enter the groundwater circulation system and are subsequently evaporated. The entrained evaporation cycle subsequently concentrates fresh water on solutes. Over time concentrated brines can be produced from aquifers at depth.
Within the salar, the brine concentration is typically most concentrated in the center of basin, within the evaporite core. Groundwater tends to be more diluted along the margins where fresh water enters the basin and becomes more brackish as the freshwater mixes with brines.
Salar basin geometry and depths are typically structurally controlled but may be influenced by volcanism that may alter drainage patterns. Basin-fill deposits within salar basins generally contain thin to thickly bedded evaporite deposits in the deeper, low-energy portion of the basin, together with thinly to thickly bedded, low-permeability lacustrine clays.
Coarser-grained, higher permeability deposits associated with active alluvial fans are commonly observed along the edges of the salar. Similar alluvial fan deposits, associated with ancient drainages, may occur buried within the basin-fill deposits. Other permeable basin-fill deposits that may occur within salar basins include pyroclastic deposits, ignimbrite flows, lava-flow rocks, and travertine deposits.
Several of the salar brines of Chile, Argentina, and Bolivia contain relatively high concentrations of lithium, likely due to the presence of lithium-bearing rocks and local geothermal waters associated with Andean volcanic activity. The conceptual model for the Hombre Muerto basin, and for its brine aquifer, is based on exploration of similar salar basins in Chile, Argentina, and Bolivia.
6.3.2 | Hombre Muerto Basin |
The salar system in the Hombre Muerto basin is considered a typical mature salar. Such systems commonly have a large halite core and are characterized by having brine as the main aquifer fluid at least in the center and lower parts of the aquifer system. Conceptual hydrogeological sections were prepared incorporating the results of exploration drilling. The Hombre Muerto basin has an evaporite core that is dominated by halite. Basin margins are steep and are interpreted to be fault controlled. The east basin margin is predominantly Pre-Cambrian metamorphic and crystalline rocks belonging to Pachamama formation. Volcanic tuff and reworked tuffaceous sediments, most likely from Cerro Galan complex, together with tilted Tertiary rocks, are common along the western and northern basin margins. In the Sal de Vida Project area, the dip angle of Tertiary sandstone is commonly about 45o to the southeast. Porous travertine and associated calcareous sediments are common in the subsurface throughout the basin and are flat lying; these sediments appear to form a marker unit that is encountered in most core holes at similar altitudes. Several exploration boreholes located near basin margins completely penetrated the flat-lying basin-fill deposits, and have bottoms in tilted Tertiary sandstone, volcanic tuff, and micaceous schist.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
6.3.3 | Hydrogeological Units |
Results of core drilling indicate that basin-fill deposits in Salar del Hombre Muerto can be divided into hydrogeological units that are dominated by six lithologies, all of which have been sampled and analyzed for both drainable porosity and brine chemistry, except for the micaceous schist. No brine samples were obtained from the micaceous schist. The predominant lithologies, meters drilled, and number of analyses are summarized in Table 6-2. It is worth noting that evaporite type rock is more predominant in the north part of the basin, currently lying under Posco mining concessions, purchased by Galaxy in 2018.
For brine estimation purposes, travertine, tuff, and dacitic gravel were grouped together based on similar drainable porosity and expected similar hydraulic conductivity. The grouping is not based on geological similarities.

DDH holes have been correlated to infer the lateral continuity of the different lithologies over the salar. Figure 6-2 is a plan view showing the location of the vertical cross-sections provided in Figure 6-3 to Figure 6-6. It is worth noting that cross-section D-D’ (Figure 6-6) actually lies over Posco mining concessions purchased from Galaxy in 2018. The same situation occurs with the north extension of cross-section A-A’ starting at approximately Well- SVH10_06 heading north (Figure 6-3). Most of the evaporites described in Table 6-2 occur in thee Posco-held concessions.

SEC Technical Report Summary
Figure 6-7 shows stratigraphic columns within the mine concessions of the salar. In general, the stratigraphic sequence is characterized by a predominance of clastic and volcaniclastic sediments with variable grain sizes and interbedded evaporites, tuff, and travertine. Surficial coarse-grained sediments of the eastern sector are largely sourced from the Rio de los Patos alluvial sub-basin and grade to finer-grained sediments in the northwest and western areas of the mine concessions due to the transition to a lower energy depositional environment. In addition, the northwest sector hosts a thick evaporite unit due to increased historical evapoconcentration and subsequent mineral precipitation. At depth, unconsolidated sediments are found in all highlighted areas and host lithium-rich brine. This sedimentary unit unconformably overlies basement rock which is mainly inferred from geophysical surveys; on the western side of the properties, Tertiary basement rock is deduced from neighboring outcrops, while Precambrian bedrock on the eastern side corresponds to the Pachamama Metamorphic Complex.

SEC Technical Report Summary
6.4 | Deposit Model |
The deposit model is summarized from Munk et al. (2016) and Houston et al. (2011). Lithium is found in four main types of deposits:
● | Pegmatites. |
● | Continental brines. |
● | Hydrothermally altered clays. |
● | Oil-petroleum deposits within salty and brine waters underneath hydrocarbons reservoirs. |
Continental brine deposits typically share the following characteristics:
● | Located in semi-arid, arid, or hyper-arid climates in subtropical and mid-latitudes. |
● | Situated in a closed basin with a salar or salt lake. Salars or salt crusts are common where brines exist in subsurface aquifers. |
● | Occur in basins that are undergoing tectonically driven subsidence. |
● | Basins show evidence of hydrothermal activity. |
● | Have a viable lithium source (e.g., high-silica volcanic rocks, pre-existing evaporites and brines, hydrothermally derived clays, and hydrothermal fluids). The nearly 5,900-m-high resurgent dome of the Cerro Galán caldera may be an important recharge area for Salar del Hombre Muerto at ~4,000 m elevation. |
● | Have an element of time-stability to allow the leach, transport, and concentration of lithium in continental brines. |
The majority of important lithium-rich brines are located in the “Lithium Triangle” of the Altiplano–Puna region of the Central Andes of South America (Figure 6-8) and are classified either as “immature clastic” or “mature halite” (Figure 6-9) types.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Figure 6-8 – Lithium Triangle.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Figure 6-9 – Schematic Showing Immature Clastic and Mature Halite Salars (Houston et al., 2011).
These salar classifications are based on:
● | The relative amount of clastic versus evaporite sediment. |
● | Climatic and tectonic influences, as related to altitude and latitude. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Basin hydrology, which controls the influx of fresh water. The immature clastic classification refers to basins that generally occur at higher (wetter) elevations, contain alternating clastic and evaporite sedimentary sequences dominated by gypsum, have recycled salts, and a general low abundance of halite. |
The mature halite classification refers to salars in arid to hyper-arid climates that reach halite saturation and have a central halite core. Houston et al. (2011) note that a key input is the relative significance of aquifer permeability which is controlled by the geological and geochemical composition of the aquifers. Munk et al. (2016) observe that immature salars may contain easily extractable lithium-rich brines simply because they are comprised of a mixture of clastic and evaporite aquifer materials that have higher porosity and permeability.
In the Salar del Hombre Muerto, a mature sub-basin exists to the west as a result of moderately evolved brines decanting from an immature eastern sub-basin over a subsurface bedrock barrier (Houston et al., 2011). A conceptual model for brine development is provided in Figure 6-10. Economically extractable lithium brines typically contain a minimum of 100 mg/l lithium concentration to more commonly 250 mg/l or more lithium. Common inflow waters may contain lithium concentrations in the range of 1 – 10 mg/l or less range. The combined effects of evaporation and precipitation of evaporite minerals concentrate the inflow waters by many orders of magnitude over time and the time-integrated flux of water through the basin must be sufficient to create a lithium brine deposit that contains sufficient total lithium to be economic, irrespective of lithium concentration.

6.5 Comments on Geological Setting, Mineralization, and Deposit Types
The knowledge of the geological setting of the salar and the associated hydrogeological systems is sufficient to support the Brine Resource and Reserve estimates. The recent drilling program of Phase 6 wells confirms the conceptualized geological setting and location of brine-bearing salar sediments. New lithologic data from cuttings and geophysical surveys confirm lithium-rich brine mineralization.
The Sal de Vida deposit shares the six common characteristics of a brine system, as outlined by Munk et al., (2016). In the opinion of the employees of Montgomery & Associates, the brine system deposit model would be a reasonable basis for the design of additional exploration programs.

Operator/Contractor | Survey Type | Date | Note |
Quantec Ltd. | Gravity | 2009, 2010 | 96 linear km across the eastern sub-basin to provide information on bedrock by density. Results suggested that the deepest part of the basin was in the center of the western sub-basin, where salar deposits may be as much as 380 m thick. |
Geophysical Exploration and Consulting S.A. | Vertical electrical sounding | 2010 | Conducted to investigate brackish or raw water–brine interface conditions beneath the margins of the Hombre Muerto basin, along alluvial fans, and adjacent to the Río de los Patos. Data interpretations suggest that highly conductive material, possibly brine, is present beneath alluvial fans along the basin margins. The following resistivity ranges were used for brackish water/salt water- bearing formations and brines: 1 ohmmeter (ohm-m) < apparent resistivity < 15 ohm-m: brackish water-bearing formations; apparent resistivity < 1 ohm-m: sea water, geothermal fluids, and brine-bearing formations. |
Quantec Geoscience Argentina S.A. | Transient electro- magnetic | 2018 | 127 measurements in five profiles. The acquired data are of high quality, and the inversion results provide a good representation of the subsurface resistivity distribution to depths ranging from approximately 100 – >400 m, varying in association with the conductivity. The surveys detected resistivity ranging from <1 ohm- m to approximately 1,000 ohm-m. Several conductive zones of resistivity of <1 ohm-m were detected. |
Mira Geoscience | 3D Gravimetry | 2021 | Objective of Project was to generate a revised depth to basement
interpretation of gravity data for the Sal de Vida area in Argentina, using geologically constrained 3D gravity forward modelling and inversion techniques. Interpretation was constrained by supporting data, including outcrop, drilling,
transient electromagnetics (TEM), and DC resistivity soundings (Vertical Electric Soundings, VES). All supplied data was imported and registered in GOCAD Mining. Data compiled comprised is: - Topographic data - Geological maps showing basement outcrop - Interpreted cross-sections - Drill data, including petrophysical data on drillhole samples (density and porosity) - Surface sample petrophysical data (Sharpe, 2010). - Geophysical data - TEM - Gravity - VES |

SEC Technical Report Summary
Prior to the drilling of the eight production wells in the east wellfield in year 2021, most of the drillholes at Sal de Vida have not encountered basement rock. Only transient electromagnetic and vertical electric sounding surveys have occurred to approximate depth to bedrock. Due to the uncertainty of depth to bedrock, Allkem contracted Mira Geoscience to interpret depth to basement using interpretation of available supporting data. Coordinate system used in this project was POSGAR, Argentina Zone 3, and interpretation and model development were carried out in GOCAD Mining Suite, which consists of a 3D forward modelling and inversion algorithm for gravity and magnetic data that operates on a geological model. The data compiled in this 3D Model project included:
● | Topographic data. |
● | Geological maps show basement outcrops. |
● | Interpreted cross-sections. |
● | Drill data, including petrophysical data on drillhole samples (density and porosity). |
● | Surface sample petrophysical data (Sharpe, 2010). |
● | Geophysical data from TEM, VES, and Gravity surveys. |

7.4 Pits and Trenches
Pits and trenches were used to establish the presence of lithium-bearing brines in the Project area, and the information collected is superseded by drill data.
The first campaign was completed by Lithium One in 2009 to verify if there were brines within the concessions. Mapping and observation of the exploration pits indicated the presence of a free-flowing aquifer transmitted through at least one poorly sorted sand and silt horizon.
A second, more detailed set of 42 trenches were excavated by Lithium One within an area of approximately 75 km2, providing an average density of one sample per 1.5 km2. Not all of these trenches are within the current Project area. The chemistry of the fluids sampled in the trenches confirmed that there was only one brine type within the salar, originating from the evaporation of influent waters.
The final pit phase was conducted in 2009-2010 by Lithium One, with 21 near-surface samples collected from excavated pits. The samples were used to obtain information on the basic physical parameters of each brine sample (e.g., pH, density, electrical conductivity, TDS, temperature, Eh).

7.5 Drilling
Drilling was conducted in several phases. These were broken out into Phase 1 to 6, with Phase 1 commencing in 2009, and Phase 6 in late 2020 as part of the East Wellfield development. The drill programs are summarized in Table 7-3, and drill collar locations are provided in Figure 7-6. Drilling Phases 1, 2, and 3 were conducted by Lithium One; Phases 4, 5, and 6 were conducted by Galaxy Lithium.
7.5.1 Phase 1
The drilling contractor for the core program was Energold Drilling Inc., (Energold) headquartered in Vancouver, Canada and based out of Mendoza, Argentina. The drill rig used for wells SVH10_05 – SVH11_15 was a DDH Energold Series 3 type. Core holes recovered HQ core sizes (63.5 mm core diameter), and, if needed to suit drilling conditions, were reduced to NQ (47.6 mm). HWT (71 mm) casing was installed in the drill holes.
Brine wells SVH09_01 and SVH09_02 were drilled by Hidroplus S.R.L. (Hidroplus) using conventional air circulation. These wells could not be cased and were abandoned. Wells SVH10_03A through SVH10_04B were drilled by Ernesto Valle, S.R.L., a firm based in the city of Salta, using conventional circulation mud-rotary drilling methods, and were cased with 4.5-inch PVC screened casing and gravel pack filter.
7.5.2 Phase 2
The core drilling contractor was Energold. Core holes recovered HQ core sizes (63.5 mm core diameter), and, if needed to suit drilling conditions, were reduced to NQ (47.6 mm). All core holes were cased with 2-inch (50.8 mm) PVC casing for use as monitor wells. The measured depth to water below the land surface was 3 m for all wells.
Drilling contractors for the brine and reverse circulation (RC) wells were Compañía Argentina de Perforaciones S.A. (CAPSA), from Mendoza, Argentina, and Andina Perforaciones S.A. (Andina), based in the city of Salta, Argentina. All brine exploration wells were cased with 8-inch (203 mm) PVC casing, except well SVWW11_07, which was cased with 6-inch (152 mm) PVC casing.
7.5.3 Phase 3
The drilling contractor was Andina. Some wells were designed to be pumping wells and some were designed to be observation wells for long-term tests. All wells were drilled by conventional mud rotary circulation. Drilled borehole diameters were 17.5 inches (444.5 mm), 12.25 inches (311.2 mm) and 8 inches (203.2 mm). Once drilling was completed, 8-inch (203.2 mm) and 2-inch (50.8 mm) blank PVC casing, and slotted PVC well screens were installed (slot size 1 mm) for monitoring wells. The pilot production wells were cased with 10-inch (254 mm) blank PVC casing and a PVC well screen (slot size 1 mm). Gravel pack (1 – 2 mm and 1 – 3 mm diameters) was installed in the annular space surrounding the well screen. A bentonite seal was installed above the gravel pack, and fill material was placed up to the level of the land surface.

SEC Technical Report Summary
7.5.4 Phase 4
A single exploration well was drilled by Andina using a rotary drill rig and completed with 10-inch PVC casing and gravel pack filter.
7.5.5 Phase 5
The exploration wells were completed by Andina (SVWW18_25) and Hidroper S.R.L (SVWW18_26) using a rotary drill rig and completed with 8-inch PVC casing and gravel pack filter.
7.5.6 Phase 6
The drilling contractor was Cono Sur Drilling, a division of Energold Drilling. The operation occurred from December 2020 to November 2021. All wells were designed to be part of the first production wellfield to provide brine to the evaporation ponds as part of the process to concentrate the brine. The wells were drilled by conventional mud rotary circulation. Drilled borehole diameters were 24 inches (609.6 mm), 16 inches (406.4 mm) and 8.75 inches (222.25 mm). Once drilling was completed, production wells were cased with 10-inch (254 mm) blank PVC casing and a PVC well screen (slot size 0.75 mm). Gravel pack (1 – 2 mm and 1 – 3 mm diameters sand) was installed in the annular space surrounding the well screen. A bentonite seal was installed above the gravel pack, then cement and fill material were placed to the level of the land surface.
A freshwater well was constructed by Cono Sur Drilling Co. during Phase 6. This well was labeled as SVFW21_21 and the drilled borehole diameters were 16 inches (406.4 mm) and 8.75 inches (222.25 mm). Once drilling was completed, the production water well was cased with a 10-inch (254 mm) blank PVC casing and a PVC well screen (slot size 0.75 mm). Gravel pack (1–2 mm) was installed in the annular space surrounding the well screen. The upper part of the well was sealed with cement.
Location coordinates and construction information for the production wells and freshwater well are given in Table 7-4.

Phase 1 | 2009 to early 2011 | Core holes | 9 | 271.0 | SVH11_15 149.0 m | Nine conventional core holes. Core was logged, recovery recorded, and the holes were analyzed for drainable porosity and brine chemistry. Results from Phase 1 indicated that basin-fill deposits in Salar del Hombre Muerto could be divided into hydrogeological units dominated by five lithologies, all of which had been sampled and analyzed for drainable porosity. |
Brine exploration wells | 6 | 1,070.2 | SVH10_04B 63.0 m | Six small diameter shallow wells were completed and one well (SVH10_04B) was used for pilot plant brine supply. Work included geological control with cutting sampling and lithological description and physical-chemical analysis of brine samples. | ||
Phase 2 | 2011 | Core holes | 6 | 894.3 | SVH11_24 195.24 m | Six core holes. The measured depth to water below the land surface was 3 m for all wells. Analytical results for drainable porosity and brine chemistry are available for all core holes. For each core hole, electrical conductivity and temperature were measured at 2–5 m intervals using an Aquatroll 200 downhole electrical conductivity probe. Using the results from the downhole electrical conductivity profiles, it was possible to identify raw-water influences in the upper part of four core holes. |
Brine exploration wells | 9 | 1,440.0 | SVWW11_13 165.0 m | Nine brine exploration wells and one reverse circulation (RC) well. Short-term pumping tests were completed on brine exploration wells SVWW11_02 and SVWW11_04 to SVWW11_13. | ||
Phase 3 | 2012 | Brine exploration wells | 5 | 651.0 | SVWW12_16 175.70 m | Five wells. Short-term (24-hour) pumping tests were conducted at each well. The pumping rate was measured using a Krohne magnetic flowmeter. Water- level measurements were taken using both electric water level sounders, and non-vented in-situ LevelTroll pressure transducers/dataloggers. Water level recovery after pumping was measured for all wells for a period of time at least equal to the pumping period. Distance from pumped wells to observation well ranged from 25–130 m. Drawdown data were analyzed for aquifer transmissivity. The results confirmed potential for production in the western and eastern areas. A recommendation was made to perform 30-day pumping tests in both areas and confirm the viability for long-term production. |
Phase 4 | 2017 | Brine exploration wells | 1 | 158.5 | SVWP17_21 158.49 m | One well completed. Activities included geological wireline logging with spontaneous-potential, long and short induction, sample splitting, lithological descriptions, and downhole brine sampling. Results from this well confirmed that the tested zone had production potential and a recommendation was made to perform a 30-day pumping test in this area and confirm the viability for long-term production. |
Phase 5 | September 2018 to March 2019 | Brine exploration wells | 2 | 535.0 | SVWP18_25 303.0 m | Two wells completed. Short-term pumping tests conducted. Brine samples were obtained at regular intervals from the discharge pipeline. Drawdown and recovery data were analyzed. The laboratory results support the interpretation that the wells may have been perforated in both the upper freshwater aquifer and the lower brine aquifer. This program provided geological and brine chemistry data that were used to characterize the southeastern area. |

7.5.8 Collar Surveys by Lithium One
A professional collar survey was conducted in 2011 of core holes SVH10_05 through SVH11_28, exploration wells SVWW11_01 through SVWW11_08, and RC drill hole SVRC11_02 was conducted using a Trimble differential global positioning system (GPS) instrument. The remaining exploration wells (SVWW11_09 through SVWW11_13) and RC drill hole SVRC11_03 were surveyed using hand-held portable GPS equipment.
7.5.9 Collar and Downhole Surveys by Galaxy Lithium
Collars since 2011 have been surveyed by Galaxy personnel using a differential GNSS instrument. Over the years 2020/2021, core holes SVH10_05 through SVH11_28, exploration wells SVWW11_01 through SVWW11_08, RC drill hole SVRC11_0240, SVWW11_09 through SVWW11_13, and RC drill hole SVRC11_03 were measured obtaining high precision position corrections, including production wells SVWP21_01 through SVWP21_08. The North and East coordinates, elevation above ground level, elevation at the wellhead and stick-up elevation were provided, through the RTK method, linked to the official reference system and reference frame.
During the exploration program, downhole electrical conductivity surveys were conducted at many of the wells after completion and boreholes to identify fresh water and brine-bearing parts of the aquifer. Following installation of 2-inch PVC in the exploration core holes, and after waiting several weeks for the brine inside the casing to equilibrate to the surrounding aquifer, a downhole electrical conductivity profile was conducted at the core holes and selected wells. Electrical conductivity is a measure of the water’s ability to conduct electricity and is an indirect measure of the water’s ionic activity and dissolved solids content. Electrical conductivity is positively correlated with brine concentration. The purpose of the profiles was to:
● | Determine the electrical conductivity profile and identify potential freshwater influence and low density. |
● | Provide additional verification for the chemistry profiles generated from depth-specific samples. |
For each core hole, electrical conductivity and temperature were measured at 2- to 5-meter intervals using an in-situ brand Aquatroll 100 downhole electrical conductivity probe. The probe was calibrated with a standard solution before each survey. Three 1-minute measurements were obtained at each depth station; the average of the three measurements was used to generate the profile. Measurements were taken only while lowering the probe through the column of brine.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
During later phases of drilling other wells were also surveyed for temperature and electrical conductivity using similar style Aquatroll probe for the purposes explained above. Downhole temperature and electrical conductivity surveys were completed on core holes SVH11_16 and SVH11_24 to SVH11_28. For each core hole, electrical conductivity and temperature were measured at 2–5 m intervals using an Aquatroll 200 downhole electrical conductivity probe. Three measurements were obtained for one minute each at each depth station; the average of the three measurements was used to generate the profile. Measurements were taken only while lowering, not raising, the probe through the column of brine, to minimize disturbance of the fluid column during measurements.
7.6 Hydrogeological and Hydrological Studies
The most notable source of fresh water to the Salar del Hombre Muerto is the Río de los Patos drainage that enters the basin from the southeast. Depth specific sampling from core holes in this area show brackish water from the water table to around 60 m depth, and brine concentrations comparable to other parts of the basin below 80 m depth. Because field data in this area are sparse, the density profile of the aquifer is uncertain in the farthest southeast part of the property where aquifer water quality may have a future effect on long-term pumping of the proposed East Wellfield.
Hydraulic conductivity in the vertical direction of groundwater flow (Kz) is typically less than hydraulic conductivity in the horizontal direction (Kh). For layered sediments, such as occur in the Salar del Hombre Muerto, the ratio Kz/Kh is commonly 0.01 or less (Freeze and Cherry, 1979). The low vertical permeability of the salar sediments, combined with the density difference between surface water inflow and deep brine, restrict the vertical circulation of fresh water entering the salar from the Río de los Patos.
Water density is typically observed to increase with depth. Fresh or brackish waters are observed within the upper 50 m of the aquifer in some locations, typically near the margins of the salar and in the south where the Río de los Patos enters the basin. Results of exploration activities suggests that most of the brackish and fresh water in the system stays in the upper part of the aquifer system, partly because it is less dense, and because fine-grained lacustrine sediments restrict downward flow. It is possible that there is some deeper freshwater input into the basin, but no fresh or brackish water zones have been observed at depth in any of the exploration holes.
Sal de Vida’s brine chemistry has a high lithium grade, low levels of magnesium, calcium and boron impurities and readily upgrades to battery grade lithium carbonate. Dense brine was observed as the interstitial fluid at all depths in the basin, typically increasing brine density with depth. In addition, although there is no borehole data currently to support this, it is anticipated that dense brine will also be located in the lower parts of the older rock units that form the margins of the basin.

7.6.1 Short-Term Pumping Tests
The following sub-sections describe the pumping tests conducted in support of the Project. Hydrological pump testing under operating conditions has demonstrated excellent brine extraction and aquifer recharge rates to support the production design basis.
7.6.1.1 Phase 2
Short-term pumping tests were completed on brine exploration wells SVWW11_02 and SVWW11_04 to SVWW11_13. All brine exploration wells were equipped with temporary submersible electric pumps, and short term (24-hours or less) pumping tests were conducted at each well to measure aquifer transmissivity, obtain a representative brine sample, and provide design data for future, higher-capacity, production wells.
Installation depths for the submersible pumps at each tested brine exploration well ranged from 32 – 91.5 m. A short step-rate pre-test was conducted at most wells to determine the pumping rate for the constant rate tests. Typically, a Krohne magnetic flowmeter was used for pumping rate measurements. Water-level measurements were taken using electric water-level sounders and non-vented LevelTroll pressure transducer/dataloggers. Pressure transducers were adjusted to compute the water-level drawdown using a brine specific gravity of 1.2 g/cm3.
The pumping period duration was 24 hours for all constant rate tests, except the test for brine exploration well SVWW11_07, which was tested for 12.25 hours due to generator failure. Core drill holes, cased with 2-inch (50.8 mm) PVC, served as observation wells during pumping tests. The distance from pumped wells to observation well core holes ranges from 14.1 – 70.4 m. Brine exploration well SVWW11_07 was in an area where there was no adjacent core hole.
Raw-water inflows were noted in the upper part of core holes SVH10_08, SVH11_15, SVH11_16 and SVH11_27. For these wells, laboratory-specific conductivity values were found to be similar to the results measured by the downhole probe. Core holes SVH10_08, SVH11_16 and SVH11_27 was located on the eastern side of the basin where mountain-front recharge of raw water, and surface water inflows, were believed to enter the groundwater system. Core holes SVH11_15 and SVH10_09 were located near the edge of a large alluvial fan in the southern part of the basin and showed profiles that suggested raw-water influence in the upper part of the well. This could be due to raw-water infiltration from the Río de los Patos into coarser fan sediments, or due to precipitation recharge from the south.
7.6.1.2 Phase 3
Most wells were equipped with temporary submersible electric pumps, and short-term (24-hour) pumping tests were conducted at each well. During testing, the pumping rate was measured using a Krohne magnetic flowmeter. Water-level measurements were taken using both electric water level sounders, and non-vented in-situ LevelTroll pressure transducers/dataloggers. Water level recovery after pumping was measured for all wells for a period of time at least equal to the pumping period. Distance from pumped wells to observation well ranged from 25 – 130 m.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Results confirmed potential for production in the western and eastern areas. A recommendation was made to perform 30-day pumping tests in both areas and confirm the viability for long-term production.
7.6.1.3 Phase 4
Exploration well SVPW17_21, was equipped with a temporary submersible electric pump, and a short-term, 48-hour pumping test was completed. SVWW11_07 served as an observation well with a distance from the pumped well of 6.13 m. The installation depth for the submersible pump was 90 m. A short step-rate pre-test was conducted to determine the pumping rate for the constant-rate tests. Pumping rates were measured with a graduated bucket and a stopwatch. Water-level measurements were taken using both electric water-level sounders, and non-vented LevelTroll pressure transducers/dataloggers. The water-level recovery after pumping was measured for a period of 38 hours.
Results from this well supported that the tested zone had production potential and a recommendation was made to perform a 30-day pumping test in this area and check long-term production viability.
7.6.1.4 Phase 5
Exploration wells SVWW18_25 and SVWW18_26 were equipped with temporary submersible electric pumps, and short-term pumping tests (48 hours for exploration well SVWW18_25 and 24 hours for exploration well SVWW18_26) were conducted at each well. Installation depths for the submersible pumps at each tested exploration well ranged from 85.5 – 89.0 m. A short step-rate pre-test was conducted at each well to determine pumping rate for the constant-rate. Pumping rates were measured with a graduated tank and a stopwatch. Water level measurements were taken using both electric water level sounders, and non-vented LevelTroll pressure transducers/dataloggers.
The water level recovery after pumping was measured for both wells for same number of minutes of pumping (2,880 and 1,440 minutes after the pump was stopped). As there were no nearby wells, no measurement of water levels at observation wells could be taken.
During the tests at exploration wells SVWW18_25 and SVWW18_26, brine samples were obtained at regular intervals from the discharge pipeline.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The laboratory results support the interpretation that exploration wells SVWW18_25 and SVWW18_26 may have been perforated in both the upper freshwater aquifer and the lower brine aquifer. This program provided geological and brine chemistry data that were used to characterise the southeastern area.
7.6.1.5 Phase 6
All production wells were equipped with temporary submersible electric pumps, and short-term pumping tests were conducted at each well. Installation depths for the submersible pumps at each tested production well ranged from 103.5 – 132.5 m. A short step-rate was conducted at each well to determine pumping rate for the constant-rate. Pumping rates were measured with a graduated tank and magnetic flowmeter. Duration of constant-rate pumping test was 36 hours for well SVWP21_02; 48 hours for wells SVWP21_01, SVWP21_05, SVWP21_06 and SVWP20_08; 52.5 hours for well SVWP21_03; and 72 hours for wells SVWP21_04 and SVWP21_07. Water level measurements were taken using both electric water level sounders, and non-vented Levelogger pressure transducers/dataloggers.
The water level recovery after pumping was measured for the same number of minutes of pumping at wells SVWP21_01, SVWP21_04, SVWP21_05, SVWP21_06 and SVWP21_07 (2,880 and 4,360 minutes after the pump was stopped). For wells SVWP21_02, SVWP21_03 and SVWP20_08 time for water level recovery measurement exceeded the time of pumping ranging from 2,580 to 6,060 minutes. During testing water level was measured at observation wells in the nearby wells at each location; however, observed water level drawdowns were too small to be used to compute hydraulic parameters because the wells were too far from the pumped well.
During the tests at the production wells, brine samples were obtained at regular intervals from the discharge pipeline. A summary of pumping tests conducted at production wells is given in Table 7-7.

7.6.2 Long-Term Pumping Tests
Two long-term pumping test campaigns were undertaken to simulate wellfield production:
● | Long-term pumping test, 2012: two 30-day tests in the western and eastern sub-basins (SVWW11_10 and SVWW11_13). |
● | Long-term pumping test, 2020: one 28-day test north of the eastern sub-basin (SVWP17_21). |
7.6.2.1 2012 Tests
Additional investigations were conducted during 2012 in two areas of the basin where aquifer conditions appeared most favorable for long-term brine production. Factors used to select these potential wellfield areas included favorable brine quality, comparatively large aquifer transmissivities and yield from existing wells in these areas, and the presumed continuity and large extent of the favorable aquifer units. To better understand the potential of these two areas, a pilot production wellfield program was designed and included new wells and 30-day aquifer tests. Long-term testing was conducted at exploration well SVWW11_13 in a simulated eastern wellfield and at well SVWW11_10 in a simulated southwestern wellfield:
● | Exploration well SVWW11_13 was pumped at a constant rate of 15.2 L/s during the period August 27 to September 26, 2012. During testing, four observation wells, SVH11_16, SVWM12_14, SVWP12_14, and SVWM12_15, were monitored for water-level changes. |
● | Exploration well SVWW11_10 was pumped at a constant rate of 9.8 L/s during the period October 19 to November 18, 2012. During testing, three observation wells, SVH11_24, SVWP12_16, and SVWP12_17, were monitored for water-level changes. |
Based on the results of the 30-day tests, the simulated wellfield locations are suitable for brine production at a rate of about 350 L/s. Because of the larger transmissivity, the efficiency of a wellfield in the eastern sub-basin may be larger and therefore result in less pumping lift; however, brine grades were more favorable, and brackish water influence was less in the western sub-basin.
Operational pumping rates were maintained throughout the pumping periods without significant encounters of subsurface hydraulic boundaries (i.e., positive, or negative boundaries caused by faulting or aquifer heterogeneities that could affect pumping water level trends). Transmissivity values were consistent with previous shorter-term testing results, being 400 m2/day for exploration well SVWW11_13 and 110 m2/day for exploration well SVWW11_10.
In the simulated eastern wellfield area, storativity values on the order of 10-4 to 10-3, derived from observation wells during pumping at exploration well SVWW11_10, were indicative of confined to semi-confined, leaky aquifer conditions.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
In the western wellfield area, due to anomalous water-level trends at observation wells during testing at exploration well SVWW11_13, storativity values were uncertain. After long-term pumping in the production wellfields, when unconfined aquifer conditions are established, the specific yield was anticipated to be on the order of 10-1.
The available data suggest that the horizontal conductivity (Kr) is one to two orders of magnitude greater than vertical conductivity (Kz), indicating that the aquifer is horizontally stratified.
Analysis of brine samples collected daily during the 30-day pumping periods indicates averages as follows:
● | Lithium concentration of 776 mg/l at exploration well SVWW11_13 and 840 mg/l at exploration well SVWW11_10; the standard deviation was 11 and 23 mg/l, respectively. |
● | Potassium concentration averaged 8,590 mg/l at exploration well SVWW11_13 and 8,351 mg/l at exploration well SVWW11_10; the standard deviation was 103 and 105 mg/l, respectively. |
● | The magnesium to lithium ratio was 2.8 at exploration well SVWW11_13 and 1.84 at exploration well SVWW11_10. |
Although hydraulic parameters indicated vertical stratification of the aquifer, the variance in critical brine chemistry parameters during the 30-day production tests was small. Similarly, no dilution of produced brine was evident during the pumping periods.
Several downhole temperature and electrical conductivity profiles were collected at pumping and observation wells, before, during, and after the 30-day long-term pumping tests in each wellfield. In general, although some variation between pre- and post-testing measurements were observable, the overall vertical electrical conductivity profiles were mostly similar or the same for all the wells. Variations in scale may be due to the accuracy of the instrument. Overall, results did not suggest that significant or demonstrable increases or decreases were observed as a result of pumping for 30 days.
For the 30-day pumping test at well SVWW11_13 in the southwestern wellfield, observation wells SVWP12_14 and SVH11_16 was measured for electrical conductivity and temperature profiles during and after testing. For each observation well, the during- and post-pumping vertical profiles for both temperature and electrical conductivity show the same shapes and shifts, particularly at observation well SVH11_16 where a dramatic shift is observed at a depth of about 57 m. However, similarly to the observation wells in the southwestern wellfield, the absolute electrical conductivity values were slightly different during and post-pumping profiles. For observation well SVH11_16, the post-pumping profile indicates a larger electrical conductivity, but for observation well SVWP12_14, the profile indicates smaller electrical conductivity values. Although it is possible that a true change in chemistry occurred, because the differences are relatively small and the profiles were measured only 24 hours apart, it is not believed that this would be sufficient time for inflow of denser or less dense water to the well that would result in these changes. Therefore, the variation may be a function of instrument calibration or accuracy.
For the 30-day pumping test at well SVWW11_10 in the southwestern wellfield, the pumped well SVWW11_10 and observation wells SVH11_24, SVWP12_16 and SVWP12_17 were measured for electrical conductivity and temperature profiles before and after testing. For pumping well SVWW11_10 and observation well SVH11_24, the pre- and post-pumping vertical profiles for both temperature and electrical conductivity are essentially the same. However, for observation wells SVWP12_16 and SVWP12_17, the post-pumping electrical conductivity profile is slightly shifted toward lower electrical conductivity values. Although it is possible that a true change in chemistry occurred, because the differences are relatively small (<10% variation), the observed change may be a function of instrument calibration or accuracy.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Based on 30 days of pumping at each wellfield, the results do not show any significant or obvious change in the aquifer water chemistry entering the wellfields during the pumping period. Minor variations may be related to instrument sensitivity and/or water mixing within the borehole.
7.6.2.2 2020 Tests
Following the results from the 2012 long-term pumping tests, a long-term test was conducted at well SVWP17_21 in the northern end of the east wellfield, which was undertaken during the period May–June 2020. The constant-rate test was planned as part of pond filling to take advantage of the opportunity to obtain long-term pumping data in the northern part of the wellfield. The test work results were used to assist with numerical groundwater flow model calibration. This basin sector is dominated by clastic sediments, with clay and sand in the upper part of the system and underlying coarse sediments (mostly gravel and sand) in the lower part where pumping occurs.
Pumping was monitored for a total of 28.8 days. Mechanical problems with the generator interrupted pumping at that time and the test was terminated. The 28.8-day duration was considered adequate for reliable evaluation of the test results. During the test, water-level drawdown was measured at the pumped well and at three observation wells, SVWP11_07, SVH11_27 and SVWP12_14, located at distances ranging from 6 – 3,300 m from the pumped well.
The flow rate was measured using a Rosemount mechanical flowmeter. The average flow rate measured during the test was 61.6 m3/hr, or about 17.1 l/s. During the 28.8-day pumping period, short-term shutdowns of the pump occurred either due to generator malfunction or maintenance. These brief shutdowns are not considered to affect the test results.
Water levels were measured using a pressure transducer and a sounder for the pumped well and observation wells. Field parameters (temperature, pH, and electrical conductivity) were measured using a calibrated multiparameter instrument. Brine density was measured using a hydrometer. Barometric pressure was also measured to correct water-level data for barometric changes. Pumped water was conveyed 1,250 m from pumped well SVWP17_21 to minimize potential interference with testing and for filling existing evaporation ponds. During pond filling, Galaxy personnel moved the discharge to different locations inside the ponds; this is not considered to have had an effect on testing.
During the test, 39 brine samples were collected. One early-time, and one late-time sample were sent to Alex Stewart Laboratories in Mendoza, Argentina (Alex Stewart) for chemical analyses. Results of the laboratory results for these two samples indicate that the chemical composition of the brine did not change during the pumping period; therefore, analysis of the remaining samples was not considered necessary.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
At the pumped well, transmissivity was calculated to be 260 m2/d using the drawdown measurements based on the Cooper and Jacob (1946) method. Recovery data are considered more reliable in general because minor changes in water level due to pumping variations were not observed. Recovery measurements at the pumped well were analyzed using the Theis (1935) recovery method; transmissivity was calculated to be 250 m2/d and is consistent with the transmissivity value calculated using drawdown data.
The distant observation wells showed little to no drawdown. About 0.4 m of drawdown was observed during pumping at observation well SVWP12_14, and about 7.7 m of drawdown was observed at observation well SVWW11_07. Similar to the pumping well, drawdown measurements at observation well SVWW11_07 show evidence of flow rate changes and generator failures at the pumped well. A transmissivity value of 320 m2/d was calculated for observation well SVWW11_07 using the Theis (1935) method). The operative transmissivity for the aquifer was calculated to be 250 m2/d.
7.6.2.3 2021 Tests
After production wells were completed in Phase 6, they were pump tested with temporary submersible electric pumps. Water level measurements were taken manually with sounders, and Levelogger pressure transducers.
Constant discharge pumping tests were conducted at all 8 production wells; water level drawdown and recovery water levels were measured with same instruments. Transmissivities and specific capacities were calculated for each production well. During testing, observation wells were used to measure water levels; drawdown was too small to compute hydraulic parameters.
Wells SVPW21_06 and SVWP21_07 have the highest specific capacities of 0.77 and 7.0 liters per second per meter of water level drawdown (l/s/m) respectively (Table 7-7).
Wells SVWP21_03 and SVWP21_07 have the highest transmissivity values of 220 and 600 m2/d respectively (Table 7-8).

7.6.3 Raw Water Wells
Two wells were completed in 2012 to identify and provide a source of raw water for mineral processing, and the camp. The wells were designed to be 8-inch diameter freshwater production wells and could also serve as observation wells during long-term testing.
Wells SVWF12_19 and SVWF12_20 was drilled in the southern section near the Río de los Patos. Each well was pumped at rates of over 20 l/s with very little drawdown, suggesting a favorably large transmissivity.
Pumping resulted in groundwater that had an average specific electrical conductivity of 2,550 μS and a TDS content of 1,500 mg/l. Although this TDS value is typically higher than accepted for drinking water purposes, these wells, or additional shallow wells in the area, are considered adequate to supply water for treatment and ultimately processing at the design rates.
Each well was pumped at rates of over 20 l/s with very little drawdown, suggesting a favorably large transmissivity. The estimated raw-water requirement for use in future brine processing is 20 – 40 l/s. The recommendation was to designate well SVWF12_19 for production and SVWF12_20 for monitoring, given the proximity to the Río de los Patos.
During Phase 6 of drilling program, a new raw water well SVFW21_21 was constructed during the period of October of 2021. Total depth was 42 m. The initial bore hole was 8 ¾ inches in diameter and it reached 36 m of depth. Downhole geophysical survey was conducted immediately after finishing exploration drilling and the borehole was reamed to a diameter of 16 inches down to a depth of 42 m. The well screen was installed 33.7 m deep with slotted PVC casing between 4 m of depth to 27.5 m. Gravel pack of 1-3 mm diameter were installed, and the well was developed. During the development, water sampling and physico-chemical measurements on this well indicated that pH ranges from 8.9 to 9.4 values.
In February 2022 a short-term pumping test was performed to infer well productivity. The water table was 3.21 m. The maximum tested pumping rate during the step-rate test was 50 l/s with a drawdown of 4.5 m. After the step-rate test a 36-hour production drawdown test followed by same time build-up was performed to estimate aquifer properties. Interpretation by Theis’ and Cooper and Jacob’s methods gave a transmissivity value of 1,574 m2/d and a storativity of 0.027, typical of unconsolidated unconfined aquifer systems.

SEC Technical Report Summary
The recommendation is to designate well SVWF12_21 for production of raw water, to be used in the process plant and for camp consumption after to be treated by the osmosis reverse plant to be installed in the area 4 (industrial facilities).
7.6.4 Stream Gauging
Stream gauging was conducted to quantify baseflow conditions, and to develop baseline measurements. Flows were measured in the Río de los Patos, and at the much smaller La Redonda stream on the northeast part of the main salar.
Measurements were conducted during relatively dry times of the year, using a Pygmy flowmeter and Aquacalc recording system, and it is considered to be reliable. Water flow readings taken in May 2011 and May 2012 indicate that there can be quite a large variation in flow rates on an annual basis. The majority of surface water inflow is believed to occur during flood events on the Río Los Patos; flow rates associated with such events have not been gauged.
7.6.5 Water Balance
A steady state water balance for the SDV project was developed over the Río de Los Patos alluvial aquifer and delta (M&A, 2020).
The following elements summarize the water balance and recharge estimates:
● | Recharge to basins similar to Salar de Hombre Muerto is typically 5–20% of its volumetric precipitation (Hogan et al., 2004). The intersection of these bounds with the evaporative discharge estimate provides an approximate range for the studied sub-basin recharge. |
● | Liquid and solid (snowmelt) precipitation in the Salar de Hombre Muerto basin is estimated to be about 106 mm/a, or as a volumetric rate, 11,050 l/s. Using 5–20% of the annual volumetric precipitation, an estimated range of precipitation recharge is likely between 550–2,210 l/s. |
● | Low, medium, and high evaporation estimates for the east sub-basin of Salar del Hombre Muerto are estimated to be 850 l/s, 1,450 l/s and 2,290 l/s, respectively. The higher evaporation estimate is slightly too large compared to the upper bound of the precipitation recharge estimate (2,210 l/s). In addition, the lower bound of the precipitation recharge estimate (550 l/s) is too low compared to the lower evaporation estimate (~850 l/s). |
● | The recharge estimate for the east sub-basin of Salar del Hombre Muerto is believed to range from 850– 2,210 l/s based on the results of intersecting the evaporation and precipitation recharge ranges. Within this range, the current best estimate for a recharge to the salar is 1,500 l/s based on the calculated medium evaporation discharge, which approximately corresponds to 13.1% of total volumetric precipitation (including snowmelt) estimated for the basin (Montgomery, Chapter 7 – Hydrology and Modelling ,2021). |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Regarding Laguna Catal, the underlying hypothesis is that surface water and groundwater movement from the Eastern Basin is conditioned by a structural dip or downthrown bedrock, which together with the difference in topography, generates a hydraulic gradient from the Eastern Basin towards Laguna Catal. The hypothesis is supported on surface geology and the difference of evaporites found at the western and eastern basins. In the Eastern Basin, the evaporites are boratiferous with low chloride content; in the western basin, thick halite accumulations are present, with little or no borates (Vinante y Alonso, 2006).
7.7 Geotechnical Considerations
Planned production includes vertical wells that allow for the extraction of lithium-rich brine through a perforated interval of the well (at depth) in clastic sedimentary deposits and evaporites. Due to the fact that the mining of this type of deposit does not involve excavations or underground workings (as with hard rock deposits), it is not necessary to carry out detailed geotechnical studies of the soil and rock strength parameters.
7.8 Conclusions
Exploration to date has identified the Sal de Vida brine, and has used exploration methodology conventional to brine exploration, such as geophysics and surface sampling, in addition to the drilling programs. In the opinion of the employees of Montgomery & Associates, the drill data and hydrogeological studies are acceptable to support the Brine Resource and Reserve estimates.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
8. Sample Preparation, Analyses and Security
The following sub-sections detail historical and recent sampling methods that have been conducted to support the Project. Sampled wells include diamond drillholes (for the analysis of drainable porosity and brine chemistry) as well as reverse circulation wells (to analyze brine chemistry).
8.1 Sampling Methods
8.1.1 Drainable Porosity Sampling Methodology
Porosity samples were collected during 2010, 2011, and 2012 from intact HQ and NQ-core. Full diameter core with no visible fractures was selected and submitted for laboratory analyses. The selected sleeved core samples were capped with plastic caps, sealed with tape, weighed, and stored for shipment. The typical sample length was 15 – 40 cm. Porosity samples were shipped to Core Laboratories Petroleum Services Division, Houston, Texas (Core Laboratories) for analysis.
8.1.2 Brine Sampling Methodology
In addition to the depth-specific brine samples obtained by drive-points during coring, brine samples used to support the reliability of the depth-specific samples included analyses of the following:
● | Brine centrifuged from core samples. |
● | Brine obtained from low flow sampling of the exploration core holes. |
● | Brine samples obtained near the end of the pumping tests in the exploration and production wells. |
8.1.2.1 Brine Sampling by Drive-Point Samplers
Brine samples were collected during 2010–2011 from the same core holes that provided porosity samples. Brine samples were collecting by removing the core barrel and installing a drive-point onto BT size (55 mm) drill rods. The drive-point was driven to a depth below the drill bit using a drop hammer on the drill rig. An impermeable diaphragm located just above the drive-point prevented the BT drill rods from being filled during driving. After driving the drive-point to the desired depth, an electric water-level sounder was lowered into the BT drill rods to ensure that the rod interiors were dry. The sounder was removed, and the diaphragm was perforated using a weighted pin lowered with the wireline. This piercing allowed brine to flow into the drive-point and begin filling the BT rods. After bailing and discarding the first fluid, the brine sample was bailed from the drill rods.

SEC Technical Report Summary
8.1.2.2 Brine Sampling by Centrifuge Phase 2
For core hole SVH11_15, a second set of centrifuge pucks was cut in 2011 from core samples at Core Laboratories, centrifuged for an extended period, and brine removed was collected and submitted to Alex Stewart for analysis. Brine was collected from a total of 15 core pucks. The volume of brine obtained by centrifuge ranged from 10–36 ml. Selected samples were split, and duplicate analyses were obtained. The results of the brine centrifuge sampling and analysis validated and confirmed the drive-point sample collection methodology.
8.1.2.3 Brine Sampling by Low-Flow Pumping Phase 2
Brine samples were collected in 2010 and 2011 by pumping selected 2-inch (50.4 mm) PVC wells to acquire composite brine samples from core holes and confirm the brine chemistry derived from other sampling methods. The average pumping rate ranged from about 1 – 4 l/min. Wells were pumped for sufficient time to remove three borehole volumes, and samples were collected for analysis. Brine samples from the low-flow sampling program, together with duplicate and standard samples were sent to Alex Stewart Assayers of Mendoza, Argentina (Alex Stewart).
For most core holes, results indicated that lithium and potassium values for low-flow pumped samples were similar to the results derived from drive-point samples.
8.1.2.4 Brine Sampling During Pumping Tests and Drilling
Brine samples were collected directly from the discharge line for analysis near the end of each pumping test for reverse circulation (RC) wells. Physical-chemical parameters including temperature, electrical conductivity, pH, and brine density were monitored during pumping. Brine samples from the pumping test program together with duplicate and standard reference material (standard) samples were sent to Alex Stewart.
For brine samples collected from pumping test at the proposed East Wellfield, lithium results obtained by Galaxy Laboratories and from Alex Stewart Laboratories were compared. A summary of results is shown for each pumping well at Table 8-1.

A graphical comparison between the results is shown in Figure 8-1. A good fit is observed between both data sets although the results from Alex Stewart lab are generally slightly lower than those of Galaxy lab. Because the data used for the Brine Resource estimation corresponds to the Alex Stewart lab, the estimated Brine Resource may be slightly conservative.

Brine samples were also collected during drilling of drill hole SVRC11_03. These samples were collected by airlift pumping from the opened borehole at 6-m intervals as the hole was drilled. These samples represent a composite sample of the drill hole at different depths. For each sample, airlift pumping rate, brine temperature, pH, electrical conductivity, and density were measured and recorded.
Brine samples from short-term pumping tests provide the best available analyses for the brine
chemistry that would be produced during production pumping. Results indicate only small variations in the lithium
(standard deviation <11 mg/l) and potassium (standard deviation <139 mg/l) content for all time-series samples.

SEC Technical Report Summary
8.2 Analytical and Test Laboratories
Porosity analyses were conducted by Core Laboratories. Core Laboratories is ISO 9000:2008 accredited. The laboratory is independent of Allkem.
Brine chemistry samples from Sal de Vida were analyzed by Alex Stewart, a laboratory that has extensive experience in analyzing lithium-bearing brines. Alex Stewart is ISO 9001 accredited and operates according to Alex Stewart Group standards which are consistent with ISO 17025 methods at other laboratories. The laboratory is independent of Allkem.
Selected duplicate samples were sent to the University of Antofagasta, Chile, as part of the quality assurance and quality control (QA/QC) procedure. The University of Antofagasta laboratory is not ISO certified but has extensive experience in the analysis of brines samples submitted from all over South America. The laboratory is independent of Allkem.
The ACME Santiago laboratory (ACME) was also used for check analysis. The laboratory is ISO 9001 certified and independent of Allkem.
Duplicate samples were also sent to ALS Chemex in Mendoza for check analyses. The ALS Chemex laboratory is ISO 17025 and ISO 9001:2000 accredited. These samples were transferred from the ALS Chemex preparation facility in Mendoza to the laboratory facility in Santiago for analysis. The laboratory is independent of Allkem.
8.3 Sample Preparation
Neither porosity (core) nor chemistry (brine) samples were subjected to any further preparation prior to shipment to participating laboratories. After the samples were sealed on site, they were stored in a cool location, and then shipped in sealed containers to the laboratories for analysis.
8.4 Analytical Methods
8.4.1 Drainable Porosity
The laboratory analytical procedure for drainable porosity by centrifuge as described by Core Laboratories consisted of:
● | Cut 38 mm (1.5 inch) diameter cylindrical plug from sample material (plunge cut or drill); typical length was about 45 mm (1.75 inch). |
● | Freeze sample material with dry ice if needed to maintain integrity. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Caliper the bulk volume of the cylindrical plug and weigh sample. |
● | Encapsulate plug (as needed) in Teflon and nickel foil, with nickel screen on ends of plugs, and weigh encapsulated sample. |
● | Calculate bulk density as: (mass of plug before encapsulation)/(caliper bulk volume). |
● | Place plug in brine and saturate under vacuum to ensure full saturation. Core Laboratories uses a standard sodium chloride brine containing 244,000 ppm NaCl. The standard brine has a density of 1.184 g/cm3, which approximates the density of brine samples collected from core holes (field measurement of 119 brine samples collected from bore holes during core drilling have a mean specific gravity of 1.18; median specific gravity for these samples is 1.19). |
● | Record weight of saturated core. |
● | Desaturate samples in high-speed centrifuge for 4 hours. Spin rates were calculated to give drainage pressure of 1 psi for poorly cemented or loose sands; and 5 psi for clay and halite. Pressure was calculated at the center of the plug placed in the centrifuge. |
● | Collect any drainage and record volume; discard drained fluid. (Fluid collected from these cores is not representative of in situ brines, due to re-saturation with NaCl). |
● | Remove plug from centrifuge and record weight. |
● | Drained fluid volume is calculated as: (saturated plug weight – drained plug weight)/1.184. |
● | Drainable porosity is calculated as: (drained fluid volume)/(caliper bulk volume). |
Screened and wrapped “pucks” of the sampled sediment were returned to the employees of Montgomery & Associates in Tucson.
Drainable porosity estimates are given as a fraction of the total rock volume and are unitless. For example, if a rock has a volume of 100 mL, and 10 mL of fluid can drain from the rock, the drainable porosity is 10/100, or 0.10. Although determined by laboratory methods, the drainable porosity is essentially the same as specific yield as defined in classical aquifer mechanics.
For boreholes SVH11_15, SVH11_22 and SVH11_25, 15 core samples were sub-sampled twice, with a centrifuge puck removed from each end of the core. The core samples were selected to be visually uniform. Results demonstrate the high variability of drainable porosity measurements but are consistent within expected porosity ranges associated with a given lithology. Analyses for drainable porosity are difficult to duplicate for the following reasons:
● | The measurement method is destructive of the samples. |
● | Duplicate samples are impossible to obtain due to natural variation of properties. |
● | Inter-laboratory standard comparisons are difficult, due to the above cited reasons. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
8.4.2 Total Porosity
After drainable porosity measurements were completed, the plug samples from the centrifuge were analyzed for total porosity. Total porosity, like drainable porosity, is given as a fraction of the total rock volume and has no units. The determinations included the following steps:
● | Oven dry sample for 5 days at 115.6º C. |
● | Weigh oven-dried sample. |
● | Assume that all weight loss is pure water lost from pore space: Therefore, volume of water lost due to oven-drying is calculated as: ((drained plug weight) – (oven-dried plug weight))/ (water density of 1 g/cm3). |
● | Total porosity is calculated as: ((drained fluid volume) + (oven drying fluid loss))/ (caliper bulk volume). |
8.4.2.1 Brine Chemistry
Table 8-2 lists the analytical methods used by the laboratories. These are based upon American Public Health Association (APHA), Standard Methods for Examination of Water and Wastewater, Environmental Protection Agency (EPA), and American Society for Testing Materials (ASTM) protocols.
Physical parameters, such as pH, conductivity, density, and TDS are directly determined from the brine samples. Analysis of lithium, potassium, calcium, sodium, and magnesium is achieved by fixed dilution of filtered samples and direct aspiration into atomic absorption (AA) or inductively coupled plasma (ICP) instruments.

8.5 Quality Assurance and Quality Control
8.5.1 Quality Assurance and Quality Control Procedure
Analytical quality was monitored through the use of randomly inserted quality control samples, including standard reference materials (SRMs), blanks and duplicates, as well as check assays at independent laboratories. Each batch of samples submitted to the laboratory contained at least one blank, one low-grade SRM, one high-grade SRM and two sample duplicates. Approximately 38% of the samples submitted for analysis were quality control samples.
8.5.1.1 Standard Reference Materials
Three SRMs were used in the 2010–2011 sampling program. These reference materials were collected from selected brine sources of known lithium concentration, Wells SVWW11_09 and SVWW11_10. The brines were collected as bulk samples, homogenized, filtered, and bottled prior to shipment for analysis. Sets of randomized replicates were sent in a laboratory round robin analysis program to five laboratories to determine the certified values used in assessing the quality of analyses.
SRM analyses at Alex Stewart indicate acceptable accuracy generally well within the mean ±2 standard deviations for all of the standards analyses. Where failures were observed, the values lie just outside of the mean ±2 standard deviation error limits. None of the failures exceeded the mean ±3 standard deviation error limits. Relative standard deviations are a measure of the reproducibility of measurements or precision of the standard. A value below 10 indicates acceptable reproducibility for a standard. The lower the value, the more precise the measurement. The relative standard deviation values for the Alex Stewart analyses ranged from 3.7 to 7.5, indicating good overall analytical reproducibility for the standard analyses conducted.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
8.5.1.2 Blanks
Blank samples consisting of distilled water have been included for laboratory analysis as part of the QA/QC program. Requested analytes for the blank samples have been the same as for the other brine samples from the wells and boreholes sent to the laboratory. Laboratory results for the blank samples have consistently reported values consistent with distilled water, with lithium being reported below detection limits.
The relative standard deviation values for the Alex Stewart analyses range from 3.0 to 7.4, indicating good overall analytical reproducibility for standard analyses conducted at Alex Stewart.
8.5.1.3 Duplicates
Sample duplicates were obtained during sample collection. Sample duplicate analyses at Alex Stewart indicated acceptable precision within 2% or less for lithium, potassium, and magnesium. All of the lithium, potassium, and magnesium laboratory duplicates were within 10% of one another and all of the samples were within the ± 10% limits. The observed bias between duplicates was within 1% and the correlation was high (r2 >0.99). All of the duplicate lithium, potassium, and magnesium analyses were within 10% and all of the samples were within the ± 10% limits.
Sample and laboratory duplicate analyses indicated acceptable precision for lithium, potassium, and magnesium analyses conducted at Alex Stewart.
8.5.1.4 Check Analyses
The round robin analytical program conducted by Lithium One at the beginning of the 2010 – 2011 drill program indicated comparable accuracy and precision to that achieved by Alex Stewart. For this reason, the University of Antofagasta was chosen as the check analysis laboratory for the 2010 drill program. Due to turnaround time delays using the University of Antofagasta, ACME was used as the check analysis laboratory for the 2011 drill program.
Fifteen percent of the original samples were sent for check analysis. In addition, blanks, low-grade and high-grade lithium SRMs were included to monitor accuracy and potential laboratory bias. The SRMs included with these samples indicated acceptable accuracy and precision for lithium and potassium. No significant bias was observed in these analyses.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
8.5.1.4.1 University of Antofagasta
Precision ranges from 5.7% for lithium to 8.4% for magnesium. Bias is acceptable and ranges from -1.7% for lithium to 7.2% for potassium. The correlation is high (r2 = 0.97 to 0.99).
Precision of these duplicate analyses is acceptable for lithium and potassium. Seventy-eight percent of the lithium analyses are within ± 10% of one another. One hundred percent of the lithium analyses are within 20% of one another. Seventy-two percent of the potassium analyses are within ± 10% of one another. One hundred percent of the potassium analyses are within 20% of one another. Only 50% of the magnesium analyses are within 10% of one another, but this percentage improves, and all of the magnesium analyses are within 20% of one another.
The magnesium analyses at the University of Antofagasta show lower precision than corresponding analyses at Alex Stewart. The reason for this greater imprecision is related to the analytical finish used by each of the laboratories. Alex Stewart uses an ICP finish while University of Antofagasta uses an AA finish. The greater imprecision at the University of Antofagasta is introduced by the incomplete digestion of microcrystals of magnesium hydroxide (suspended in the brine) by lower plasma temperatures used during AA analyses.
8.5.1.4.2 ACME
Precision ranges from 7.4% for potassium to 9.1% for lithium. Bias is acceptable and ranges from -1% for magnesium to 5.3% for potassium. Correlation is high (r2 = 0.90 to 0.96).
Sixty-eight percent of the lithium analyses are within ± 10% of one another. Ninety-four percent of the lithium analyses are within 20% of one another. Fifty percent of the potassium analyses are within ± 10% of one another. Ninety-seven percent of the potassium analyses are within 20% of one another. Sixty-eight percent of the magnesium analyses are within 10% of one another, but this percentage improves and 91% of the magnesium analyses are within 20% of one another.
The ACME results display slightly poorer reproducibility for lithium and potassium than the University of Antofagasta check analyses. This lower precision is also reflected within the set of laboratory duplicates analyzed by ACME within the check analyses program. This suggests that the imprecision observed between the original ASA analyses and the ACME check analyses is not only a function of the sample difference, but incorporates the imprecision contributed by ACME’s inability to reproducible analyses to the same precision level as Alex Stewart or University of Antofagasta. Regardless of the precision comparison, the population standard deviations and means between the sets of data for Alex Stewart and ACME are not statistically significantly different.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
8.5.1.4.3 ALS Chemex
Three non-certified SRMs were used. Brine fluids were collected from selected surface brine pools of known concentration which have undergone significant mixing and homogenization and were included as control samples with the check samples. Three ALS analyses exceeded the +10% accuracy limits, appear to be analytical outliers, and could be classified as analytical failures.
ALS Chemex laboratory lithium analyses for Standard 1 were generally half of the value of the Alex Stewart analyses. As the concentration of lithium increased to above 300 mg/l for Standards 2 and 3, (excluding an obvious analytical outlier of 952 mg/l for Standard 2), the mean difference between lithium analyses by each laboratory decreases from over 50% for Standard 1 to within 6% for Standards 2 and 3.
Although there is a significant bias at low concentrations, analyses of lithium at higher grades are within 6% of one another and are considered to be within acceptable limits of analytical reproducibility.
Standard analyses at ALS Chemex are more variable than those at Alex Stewart, but still generally within +10% of the mean and +2 standard deviations.
Duplicate analyses at ALS Chemex show more variable results than those performed at Alex Stewart, but still indicate acceptable precision of less than + 10% for the sample duplicates, with only one sample exceeding a precision of + 10%.
Check analyses were conducted at ALS Chemex using duplicate samples. The correlation between Alex Stewart and ALS Chemex analyses ranges from 0.94 for magnesium to 0.98 for lithium and potassium. Precision of these duplicate analyses is acceptable, but there is an analytical bias between the laboratories. ALS Chemex analyses are biased 4.9% for potassium, which is within analytical acceptability, to 21.1% for magnesium, which is significantly lower than corresponding Alex Stewart analyses. ALS Chemex lithium analyses are biased 11.5% lower than corresponding Alex Stewart analyses. This bias is observed throughout the range of grades analysed, and most likely reflects instrumental calibration bias between the laboratories.
Check analysis statistics for pH, density, and conductivity between Alex Stewart and ALS Chemex were evaluated. The parameters are measured with different instrumental methods than lithium, potassium, and magnesium. Correlation of check analyses between the laboratories ranges from 0.73 for pH to 0.99 for conductivity. Accuracy and precision are within acceptable limits (<10%) and there is no significant bias between physical measurements conducted at either laboratory.
8.5.2 Anion-Cation Balance
Another measure of accuracy of water analyses involves determining the anion-cation balance of the samples. The accuracy of water analyses may be readily checked because the solution must be electrically neutral. Thus, the sum of cations in meq/l should equal the sum of anions in meq/l.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The term meq/l is defined as: Meq/l = mg/l * valency / formula weight.
The charge balance is usually expressed a percentage, where:
If the balance calculated by this formula is <5%, the analysis is assumed to be acceptable. The anion-cation balances for all of the samples analyzed at Alex Stewart have a balance within a value of 5.0. Overall, the Alex Stewart analyses show acceptable accuracy and precision, and anion-cation balance such that the data can be used in Brine Resource estimation.
8.6 Databases
In the early phases of the Project, all data were transferred into a central data repository managed by Montgomery & Associates and other consultants. The database was originally located in Denver, Colorado and later synchronized with a data repository in the Project offices in Argentina, and a separate data repository at Montgomery & Associates’ offices in Tucson, Arizona. Currently, Allkem manages the main database.
Raw data from the Project were transferred into a customized Access database and used to generate reports as needed.
Field data were transferred by field personnel into customized data entry templates. Field data were verified before being uploaded into the Access database using the methodology of crosschecking data between field data sheets and Excel tables loaded in the server. Data contained in the templates were loaded using an import tool, which eliminated data reformatting. Data were reviewed after database entry.
Laboratory assay certificates were directly loaded into the Access database, using an import tool. Quality control reports were automatically generated for every imported assay certificate and reviewed to ensure compliance with acceptable quality control standards. Failures were reported to the laboratory for correction.
The drainable porosity and chemistry data to support the Brine Resource estimates were verified. These verifications confirmed that the analytical results delivered by the participating laboratories and the digital exploration data were sufficiently reliable for Brine Resource estimation purposes.

8.7 Sample Security
All samples from the Lithium One and Galaxy Lithium programs were labelled with permanent marker, sealed with tape, and stored at a secure site until transported to the laboratory for analysis. Labels were hand-written in accordance with the chain-of-custody field data sheets. Samples were packed into secured boxes with chain-of- custody forms and shipped to the relevant laboratory.
8.8 Sample Storage
All core and drill cuttings are stored in Allkem’s Catamarca office.
8.9 Conclusions
Sample collection, preparation, analysis, and security for the drill programs are in line with industry-standard methods for brine deposits.
The Alex Stewart analyses show acceptable accuracy and precision with an acceptable anion–cation balance. Check analyses at University of Antofagasta and ACME validate lithium and potassium analyses conducted at Alex Stewart. The lower bias observed in the ALS Chemex data for lithium, potassium and magnesium is most likely due to calibration differences between the ICP and AA instruments used to analyze the samples.
Drill programs included QA/QC measures. QA/QC program results do not indicate any problems with the analytical programs.
The employees of Montgomery & Associates are of the opinion that the quality of the sample preparation, security, and analytical procedures are in accordance with industry standards, and are sufficiently reliable to support the Brine Resource and Reserve estimates.
The conceptual understanding of the hydrogeological system of Salar del Hombre Muerto is good, and the observed drilling and testing results are consistent with anticipated stratigraphic and hydrogeological conditions associated with mature, closed-basin, high altitude salar systems. One of the most important features of this hydrogeological system is the general consistency of the lithium and potassium grades measured throughout the entire salar. The majority of the salar contains high-density brine with an average lithium grade over 700 mg/l. The identified aquifer units in the basin are shown to be aerially extensive with a demonstrated ability to pump brine.

9. Data Verification
The following chapter summarizes the data verification processes and methods utilized for the Project.
9.1 2010 Technical Report
The following is a summary of the data verification performed in support of the 2010 Technical Report.
Lithium One carried out an internal validation of the available assay data for the 51 sample sites. Data verification was completed on the entire set of samples for each sample collected in the second sampling campaign. This included Alex Stewart and ALS Chemex values for pH, density, conductivity, TDS, sulphate, Cl, alkalinity, B, Ca, K, Li, Mg, and Na. No data errors were found.
Verification of the location of trenches and samples collected by use of differential GPS was also conducted.
The employees of Montgomery & Associates concluded that the information was acceptable to support Brine Resource estimation.
9.2 2011 and 2012 Technical Reports
The following is a summary of the data verification performed in support of the 2011 and 2012 Technical Reports. Lithium One implemented a series of industry-standard routine verifications to ensure the collection of reliable exploration data. Documented exploration procedures existed to guide most exploration tasks to ensure the consistency and reliability of exploration data.

10. Mineral Processing and Metallurgical Testing
10.1 Initial Brine Characterization and Scoping Studies
10.1.1 Raw Brine Metallurgical Characterization
The chemical composition and physical properties of raw brine from production wells are displayed in Table 10-1. These measurements are taken from 7 different production wells and analyzed by the onsite laboratory.
Table 10-1 – Characterization of raw brine.
The lithium concentration is above 800 mg/l, which is relatively high when compared with other Argentine brines. The relative concentration of the other elements with respect to lithium must be reduced prior to production of lithium carbonate. Large amounts of sodium, potassium, strontium, and chloride can be removed by evaporation prior to liming, via precipitation of salts. Calcium, magnesium, sulphate, and boron must be reduced by other means. The SDV process for removing these contaminants and producing the final lithium carbonate product is outlined in Section 14.
10.1.2 Final Product
Lithium carbonate is a salt of lithium and is produced as a white granular solid which exists exclusively in an anhydrous form. Details on the characterization of lithium carbonate product from the SDV pilot plant can be found in Section 10.2.10.

10.2 Metallurgical Laboratory Test-Work Program
10.2.1 History
Galaxy conducted a series of internal and external testwork programs to determine the feasibility of producing battery-grade (BG) lithium carbonate from the Sal de Vida Project. Both external laboratories are fully certified and highly regarded in the resource industries.
A conventional brine flowsheet was initially investigated that used common unit operations for lithium brine processing. The initial design also included a potash plant for production of saleable potassium chloride, processed from the salts precipitated in the muriate solar ponds. The initial flowsheet and unit operations are summarized in Table 10-2.
Table 10-2 – Initial testwork flowsheet.
Operation | Element Targeted | Description |
Solar evaporation | Na, K, water | Evaporation of brine in ponds to remove water. Precipitation of sodium and potassium as halite and sylvite salts in halite and muriate ponds respectively |
Liming | Mg, B, SO4 | Reaction of brine with calcium hydroxide (Ca(OH)2) to remove magnesium, sulphate and some boron as magnesium hydroxide, calcium sulphate and borate solids |
Solvent extraction (SX) | B | Removal of boron by pH adjustment and contact with an organic extractant |
Ion exchange (IX) | B, Ca, Mg | Eluting of brine through a column with a resin with a high affinity for calcium, magnesium and/or boron |
Softening | Mg, Ca | Reaction of brine with sodium carbonate (Na2CO3) and/or caustic soda (NaOH) to precipitate calcium and magnesium as calcium carbonate and magnesium hydroxide solids |
Crystallization | Li | Precipitation of lithium carbonate (Li2CO3) crystals by reaction with sodium carbonate at elevated temperatures |
Bicarbonation | Li | Purification of lithium carbonate by reacting with carbon dioxide to produce soluble lithium bicarbonate (LiHCO3), filtration to remove solid impurities and recrystallisation of refined lithium carbonate by heating to >75 °C and expulsion of CO2 |
10.2.2 Evaporation Rate Dynamics
A standard Class A pan test was performed on site between 2011 – 2013 to understand the evaporation rate dynamics on the salar. This involved taking daily readings of the pan and replenishing the amount of water that had evaporated during the previous day. A 16 wt% NaCl solution was used. The gross evaporation (inclusive of rainfall) for each month was recorded. The relation between the NaCl solution activity and density was used to estimate the equivalent evaporation rate of pure water. The study outcomes and established correlations were used to estimate a preliminary evaporation rate for modelling purposes.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
10.2.3 Liming and Concentration Pathway Testwork
Testwork was performed on site in 2012 to generate concentration path data from limed brine. Raw brine was limed batchwise, then evaporated to different final concentrations in six 3-m and 6-m test ponds, with daily sampling and ion analysis. The results were used to plot sodium and potassium concentrations as a function of lithium concentration. Results indicated that raw brine could be evaporated to 2.2 wt% Li without lithium precipitation.
10.2.4 Galaxy-Jiangsu Lithium Carbonate Plant
Galaxy commissioned its Jiangsu lithium carbonate plant in China to investigate the applications of solvent extraction (SX), ion exchange (IX), softening, and crystallization.
Jiangsu was requested to perform boron SX testwork to provide a greater understanding of the applicability of a boron SX circuit in the process. Jiangsu conducted several softening optimization testwork to determine its effects on the circuit’s performance, conducted optimization testwork for Ca/Mg IX and boron IX, and optimization testwork for the crystallization circuit. This option was not pursued further.
10.2.5 Hazen Research Inc.
Hazen Research Inc. of Golden, Colorado (Hazen), completed bench-scale testwork and larger batch tests using a supplied 50 kg evaporated brine (2.2 wt% Li) produced on site. Hazen first performed a process review and testwork program to determine the most appropriate extractant for boron removal, which was found to be 2,2,4-trimethyl-1, 3-pentanediol in iso-octanol (Exxal 8). Bench-scale testwork for calcium and magnesium removal with sodium carbonate (Na2CO3) was also performed prior to the larger-scale runs.
The Hazen testwork demonstrated that a primary-grade (PG) lithium carbonate could be produced from a 2.2 wt% Li brine, at a larger scale than bench work. The testwork also provided some insight into optimal conditions and the flowsheet arrangement; for example, including caustic addition to target pH 10.4 prior to softening via sodium carbonate addition reduced the quantity of reagents required.
10.2.6 Galaxy Testwork
In 2018, Galaxy conducted IX scoping tests using two types of chelating resins: LSC 750 and LSC 780, with a high selectivity to divalent cations (magnesium and calcium) and boron respectively. Results indicated that IX, with an appropriate resin, could reduce the impurities in concentrated 2.2 wt% Li brine by 88% for calcium, 97.5% for magnesium and 99% for boron.

SEC Technical Report Summary
10.2.7 ANSTO
10.2.7.1 Laboratory Testwork – Stage 1
The Australian Nuclear Science and Technology Organization (now ANSTO Minerals; ANSTO) was contracted to provide ongoing validation testwork. Site brine samples were produced on site for ANSTO testwork by evaporating wellfield brine in 6-m pans. This testwork was performed using 2.2 wt% Li evaporated brine samples. The investigations performed included:
● | SX and IX testwork for boron, calcium, and magnesium removal. |
● | Softening investigating Na2CO3 and NaOH addition testwork for removal of calcium and magnesium and pH adjustment. |
● | Crystallization of primary Li2CO3. |
● | Lithium carbonate purification by bi-carbonation, IX, and re-crystallization. |
The key findings were:
● | SX and IX for boron removal are not required as almost all boron is rejected during the crystallization of primary lithium carbonate as well as recrystallisation of refined Li2CO3. |
● | Recycling of mother liquor from crystallization can be achieved without the inclusion of a specific boron- targeted removal step. |
● | The divalent cations, calcium, and magnesium can be mostly removed by addition of NaOH, Na2CO3 and/or a combination of the two. A combination of the two can easily reject all divalent ions but presents risks of lithium losses. |
● | IX treatment to removal calcium and magnesium is not required prior to precipitation of primary Li2CO3. |
● | Bicarbonation, followed by clarification, results in rejection of the majority of divalent carbonates as these carbonates are largely insoluble, while lithium bicarbonate is highly soluble. |
● | Some sodium and potassium are rejected during bicarbonation/clarification. |
● | Control of the crystallization of Li2CO3 is vitally important to minimizing sodium and potassium contamination in the final product. |
● | With the baseline flowsheet, IX for divalent cation removal after bicarbonation would always be required to produce BG product. |
The primary recommendation was to investigate the effect of liming as an impurity removal step, and to adopt the simplified process flowsheet set out in Figure 10-1.

10.2.7.1.1 Small-Scale Evaporation
Evaporation testwork was performed on site with site produced brine, evaporated under ambient conditions in ~50 cm plastic trays. Through routine sampling to track ion concentrations, modelling of the brine concentration pathway and density changes during evaporation was updated. The data can be found in Table 10-3. This work was validated by similar evaporation testwork performed in Perth, under heat lamps (Bureau Veritas (BV) and Nagrom).

The major outcomes included:
● | Raw data were obtained to further validate concentration pathway correlations. |
● | The work performed in Perth revealed that some lithium would precipitate as potassium lithium sulphate (KLiSO4) beyond a concentration of 1.2 wt.% Li in the brine. As a result, the evaporation limit for process design was lowered from 2.2 wt% to 1.2 wt%. |
10.2.7.1.2 Single Go Forward Option
A single go forward option was determined, based on the following considerations:
● | Liming will be performed after evaporation of the raw brine rather than upfront. This will reduce the throughput volume of the liming plant and hence the capital cost. There is also potential for the cost to be deferred until later in the Project timeline. |
● | The Sal de Vida plant will produce a primary grade Li2CO3 that can then be shipped elsewhere for purification or sold to customers. This will be more economically favorable as it allows for a simplified flowsheet to be used on-site, while purification can be performed offsite, without the constraints of isolation and altitude. |
The flowsheet selected for the proposed on-site process plant and subsequent process development is provided in Figure 10-2.

10.2.7.2 Laboratory Testwork – Stage 2
The ANSTO Stage 2 testwork was performed on a combination of synthetic and site-produced evaporated brines, targeting a range of lithium concentrations. Two programs were completed.
10.2.7.2.1 Program 1
Work performed included:
● | Evaporation profiles to investigate the impact of sulphate concentration. |
● | Characterization of the effect of liming on calcium, magnesium, and SO4 concentrations at 0.7 wt% Li. |
● | Multi-step validation to help determine the best sequence of liming, evaporation and softening for optimum impurity removal and lithium recovery. |
Findings included:
● | Lithium precipitates at an earlier concentration than previous testwork had indicated — after 0.7 wt.% Li rather than 1.2 wt.% Li – but this can be prevented up to at least 1.2 wt% Li by keeping sulfate concentrations below 3.2 wt%. |
● | Lime is more effective in less concentrated brines. |
● | Magnesium that is not removed in liming can be removed in the softening circuit. |
● | Softening performance is not affected by reaction temperatures between 20–40°C. |
● | Li2CO3 can be produced at a purity above 99% using the recommended flowsheet. The dominant impurities are sodium, potassium, and chlorine. |
The flowsheet was modified (Figure 10-3) to place liming between the two stages of evaporation ponds, rather than before or after. The halite ponds evaporate the brine to 0.7 wt% Li, after which the brine is limed to remove magnesium, then evaporated again in muriate ponds to a target of 1.2 wt% Li. The intermediate liming stage removes sulfate, which affects the chemistry of the brines such it can be evaporated beyond 0.7 wt% Li without precipitation of lithium.

10.2.7.2.2 Program 2
Work completed included flowsheet validation testwork, ‘locked-cycle’ testwork (replicating the inclusion of anticipated recycle streams) with site reagents, investigation into liming temperature, and solid–liquid separation assessment for liming, softening and crystallization.
Findings included:
● | High purity Li2CO3 (99.5%) can be reproducibly prepared using site reagents and site brine. |
● | Liming slurries demonstrated fast filtration rates of 400–800 kg/m²/hr, resulting in a cake moisture of 66 – 70%. |
● | Softening slurries demonstrated slow filtration rates ranging from 100 kg/m²/hr to 10 kg/m²/hr. Perlite filter aid did not improve the performance. However, repulping softening slurry with liming thickener underflow increased the filtration rate by two to three times. |
● | Li2CO3 can be readily filtered at a fast rate based on the Li2CO3 filtration tests. |
10.2.8 Class A Pan Evaporation Rate Measurement
Additional Class A pan tests using 16 wt% NaCl solution commenced in March 2020 to monitor site evaporation and collect modelling data in the area of the site camp and pilot ponds. Daily density, brine activity and pan level decrease measurements were recorded, with the level maintained through the addition of purified water. In November 2021, another Class A pan was installed in the industrial ponds area. This testwork program was in progress at the Report effective date, with the collected data to be used for validation and expansion of the 2011 – 2013 Class A pan data.
As of August 2023, the Class A pan tests have collected over 3 years’ worth of evaporation data in the vicinity of the camp and pilot ponds and almost 2 years of data in the industrial ponds area, which have compared favorably with the values used in evaporation pond design (which were based on the 2011 – 2013 Class A pan measurements and larger datasets from nearby operations). Figure 10-4 shows the average daily evaporation broken down by month, comparing it to the design evaporation rates.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Figure 10-4 – Daily Net Evaporation Measured by Class A Pan Test.
The Class A pan results indicate that the monthly evaporation rates in this area are generally higher than the design rates, meaning that the evaporation pond design is conservative.
Additional Class A pan tests are underway using site brine, limed and un-limed, at concentrations representative of the conditions in the evaporation ponds. These tests will be used to validate the effect of brine composition on evaporation rates.
10.2.9 Pilot Ponds
The pilot ponds consist of 31 ponds of various sizes arranged in 5 strings (Figure 10-5). The ponds are numbered according to string and pond number, e.g., H51 is the first pond in String 5. Each string can be used for a different activity or purpose.
The pilot ponds are subject to routine surveys in which the levels of the brine and salt beds are measured. In late 2020, the temperature profile across the time of day was recorded once or twice per month to understand how the pond temperature responds to changes in the ambient temperature. Pond samples from the ponds are laboratory analysis for ion concentrations when needed to track the concentration path.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
10.2.9.1 April 2020 – February 2021 – Batch Evaporation
The brine for Run 2 in the pilot plant (see Section 10.2.3) was evaporated batchwise in the String 4 H and K ponds along with H53 and H54, which were consolidated as needed to adjust the surface area (and hence the evaporation rate) such that the brine would reach the correct lithium concentration in the brine (0.7%) when the team was ready to begin the liming operation (Figure 10-5). When the brine concentration of lithium reached 0.7%, it was transferred to R5 to minimize evaporation as it was processed through the liming plant. Following liming, the brine was pumped to R4 for continued evaporation to a 1.2% lithium concentration, before being transferred to storage tanks to feed the softening circuit.
H11 was slated for salt harvesting testwork, so in late 2020 it was filled with raw brine with the intention of building up a salt layer thick enough for harvesting in 2022. Other ponds were used for disposal of various waste brines, including raw brine from well pump tests (H51, H52, H12) and pilot plant waste (R3).

10.2.9.2 February 2021 – February 2022 – Continuous Pond System
At the end of February 2021, a continuous pond system was implemented in String 5, wherein brine was continually pumped from the holding pond B4 into H51 and flowed through the weirs into K51. The operation was later expanded into String 4 by pumping the brine across to K41, allowing it to flow through the weirs to H41 where it was pumped to storage pond B3. This exercise allowed the site team and technical support to develop experience with operating and controlling a continuous system through changing evaporation rates and weather conditions, including snow and rain. B2 was used as additional storage when B3 became full (Figure 10-6).
The brine from Strings 2 and 3 was consolidated into H24 as it approached 0.7% Li. This pond was used to feed the liming plant during the 2021 liming exercise for pilot plant Run 4. The limed brine from this exercise was stored in R4 for further evaporation to 1.7%, at which point it was transferred to the plant storage tanks to be used for softening operations. Regular sampling of the limed brine during evaporation allowed the concentration path to be defined for limed brine from the liming plant output concentration (0.6%) to the softening feed concentration (1.7%), with the results used for pond modelling. R3 continued to be used for pilot plant waste disposal.
10.2.9.3 February 2022 – Salt Harvesting
In February 2022, H11 was drained and harvested. Earthmoving equipment constructed ramps for ingress and egress, and a layer of approximately 30 cm was removed according to a procedure developed by the site team, leaving a sacrificial salt layer of approximately 20 cm. The exercise allowed the team to gain experience in salt harvesting and was used to update the harvesting procedure for operational readiness for the commercial ponds. In addition, a report was issued detailing the amount and composition of the entrained brine recovered and the properties of the harvested salt.
The key findings of the salt harvesting test were:
● | Demonstrating the feasibility of harvesting salt precipitated from SDV brine. |
● | Demonstrating that a sacrificial salt layer of 20 cm is relatively adequate (only one leak was detected). However, harvesting in the industrial ponds will utilize a sacrificial layer of 30 cm to be conservative. |
● | An initial (pre-drain-and-squeeze) entrainment factor of 0.21 t of brine per t of dry salt was calculated. |
● | A recovery factor of 0.12 t brine per t of dry salt was calculated for the entrained brine during the harvest (i.e. more than half the 0.21 tonnes of entrained brine can be recovered from each tonne of harvested salt). |

10.2.9.4 February 2022 – June 2022 – Continuous Production
Beginning in February 2022, the continuous pond system was expanded across Strings 3 and 2 (Figure 10-7), with the evaporated brine being stored in B2 (with B3 being used to store the existing evaporated brine from the operation thus far). The mode of operation was also changed to a production focus, with the goal of producing ~50 m³ of evaporated brine at 1.0% Li per day once at steady state and maintaining this concentration in the storage pond.
This operation continued until June 2022 and allowed the site team and technical support to gain experience in operating the continuous ponds in the same manner that will be employed in the commercial process. The production target was exceeded, with an average of 64 m³ produced per day.

10.2.10.1 Liming 2020 (Run 2)
Liming was performed in Run 2 in August 2020, with 360 m³ of brine processed over 21 days. The process included lime slaking, the liming reaction and solid–liquid separation to remove the solids produced. Operational observations and outcomes included:
● | Only on-specification limed brine was produced, validating the laboratory testwork. |
● | Filter press cycle time of 40 min was achieved. |
● | Operational targets were adjusted to account for the differences in process conditions compared with laboratory testwork. |
● | The impact of commercial lime quality on slaking temperature and magnesium removal was examined, highlighting the impact of poor-quality lime on process control. |
● | Thickener data were obtained, validating the settling properties of the liming solids. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
10.2.10.2 Softening 2020 (Run 2 – 3)
The softening circuit was run during October 2020 for Run 2, processing 37 m³ of evaporated limed brine at 1.2% Li and producing approximately 27 m³ of on-spec softened brine over seven days. The circuit was run again for Run 3 in November, processing a further 40 m³ of 1.2% limed brine and producing 32 m³ of on-spec softened brine over seven days. Caustic addition was followed by sodium carbonate addition in a series of cascading tanks, and the resulting slurry was filtered to remove the solids. Key findings were:
● | Validation of laboratory testwork, with calcium and magnesium reduction exceeding expectations. |
● | Excellent filtration performance, with cake moisture levels around 50% versus the expected 70%. |
● | Some of the solids exist as fine particulates which can pass through the filter press cloths. If not immediately filtered with a cartridge filter or similar, these solids can re-dissolve and re-introduce calcium and magnesium to the liquor. This highlights the importance of effective removal of fines immediately following press filtration and informed the large-scale plant design. |
● | If necessary, off-specification softened brine can be re-treated to bring the brine back on-specification. |
● | Variation in temperature above 20°C has no effect on softening performance — therefore, 20°C was selected as the desired operating temperature. |
● | Circuit stability is important to softening performance. |
10.2.10.3 Lithium Carbonate Crystallization 2020 (Run 2 – 3)
The crystallization circuit was operated in late October 2020 as part of Run 2. Brine from Run 2 softening was heated to 70°C and sodium carbonate was added to precipitate lithium as lithium carbonate, which was recovered by filtration and subject to a repulp wash followed by secondary filtration with a displacement wash of 1 kg water per kg cake. Over 300 kg of washed lithium carbonate cake was produced at approximately 30% moisture, after processing 17 m³ of softened brine. The circuit was operated again in December 2020 as part of Run 3, processing a 25 m³ of brine from Run 3 softening to produce 600 kg of washed lithium carbonate cake. Unlike in Run 2, the cake was recovered by centrifugation and washed within the centrifuge with a displacement wash of 6 kg water per kg cake. The following were noted:
● | Due to the high temperature and low atmospheric pressure, evaporation of brine resulting in saturation of sodium was a potential issue. To combat this, the sodium carbonate solution was diluted to 20% and additional dilution water was added to the brine heating tank. |
● | Short circuiting presented a risk due to up-comers in mixing tanks becoming blocked. Regular cleaning will be required. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Product quality depends strongly on having a stable process. Short circuiting, blockages and stopping/starting can cause major process upsets and reduce product quality. |
● | Lithium dissolution loss during repulp washing presented a serious issue, especially at lower temperatures. This highlights the importance of temperature control and suggests that the use of a saturated lithium solution may be beneficial for washing. |
● | Repulp washing, followed by a secondary filtration with a displacement wash, was required to achieve TG specifications when using vacuum filtration to recover the product (Run 2). When recovering product with centrifugation (Run 3), only a displacement wash was required. This confirmed centrifugation as the preferred solids recovery method from both a purity and recovery perspective. |
● | Validation of and improvement over laboratory testwork, with TG (99.5% lithium carbonate) achieved whenever the process was stable, and BG specifications achievable for all elements except Ca and Mg. |
10.2.10.4 Vendor Testwork
The pilot plant produced a variety of samples suitable for additional testwork. This testwork was conducted at external vendors’ facilities and the results informed the design of the plant for optimum operational efficiency.
10.2.10.4.1 GBL Thickening and Pressure Filtration
GBL were supplied representative samples of the liming, softening and crystallization slurries produced on site, to conduct thickening and pressure filtration test work. The test work was performed to:
● | Calculate TDS for each process liquor – liming, softening, crystallization. |
● | Define thickening properties – liming, softening, crystallization. |
● | Test the suitability and performance of the DrM Fundabac pressure filter (proprietary candle filtration unit) – softening. |
● | Test the suitability and performance of plate and frame pressure filtration – softening, tailings. |
● | Determine the sizing parameters for each duty. |
The primary findings were:
1. | Liming slurry |
● | % solids measured at ~4.5 wt.% (excluding TDS). |
● | The diluted liming slurry settled well without the use of flocculant. |
● | Feed dilution was optimal at ~1 wt.% solids. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Solids flux rates ranged from 0.005 – 0.02 t/m2/h with associated rise rates of 0.36 – 1.46 m/h. |
● | The highest underflow solids concentration achieved was 31 wt.%. |
● | The TDS was measured at 68 % water content and 32 % salt. |
2. | Softening slurry |
● | % solids measured at ~6.7 wt. % (excluding TDS). |
● | The sample did not settle well with or without the use of flocculant. |
● | Pressure filtration (Nutsche and TSD [replicating candle filtration]) was fairly slow, with flux of 20 to 50 t/m2/h with reasonable cake thickness and specific solid throughput of 4 to 18 kg/m2/h – depending on conditions and use of filter aid. |
● | 55 wt.% and 23 wt.% moisture for the Nutsche and candle filter respectively. |
● | Specific solids throughput for tests without filter aid ranged between 3-12 kg/m2/h, with specific solids throughput ranging between 38-40 kg/m2/h where filter aid was body-fed. |
● | The TDS was measured at 72 % water content and 28 % salt. |
3. | Crystallisation slurry |
● | % solids measured at ~6.4 wt.% (excluding TDS). |
● | The undiluted Crystallisation slurry settled well without the use of flocculant. |
● | Feed dilution was optimal at ~2.5 – 6.4 wt.% solids. |

● | The TDS was measured at 76 % water content and 24 % salt. |
4. | Tailings slurry |
● | A mixing ratio of 5.8:1 (wt.% DS / wt.% DS) for liming versus softening solids was applied when mixing liming underflow with softening wet cake to create a tailings sample. |
● | The water content of the filtered cake measured 50.6 wt. %. |
● | Specific solid throughput was 7 kg/m2/h. |
Andritz were supplied representative samples of the crystallisation slurry and Li2CO3 cake produced on site, to investigate the application of a centrifuge for dewatering and displacement washing of the Li2CO3 final product. Andritz were also engaged to provide feedback on the extent of dewatering achievable and the positioning and sizing of a centrifuge within the circuit. The primary findings were:
● | Trials with pilot plant samples were in good alignment to Andritz’s previous experience with lithium carbonate. |
● | Feeding the centrifuge directly from the reactor is possible however a feed solid content of ~20 w/w% is recommended. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Feeding the centrifuge at lower solids content results in a prolonged filling phase hence cycle time and reduced throughput of the machine. A cyclone to pre-thicken the feed to 20 w/w% may be more viable than a larger centrifuge size. |
● | The lowest residual moisture achieved with repulp washing of the lithium carbonate from site was 10 w/w%. |
● | The bench-scale drying test was successful. No encrustation or lump formation during drying was observed. A residual moisture of 0.1 w/w% was achieved. |
10.2.10.5 Battery-Grade Development Program
Toward the end of pilot Run 3 in 2020, several hypotheses were tested to understand their impact on the product quality. Results obtained during these tests indicated an improvement in product quality. High-grade product from Run 3 achieved BG specification in all elements except for calcium and magnesium (Table 10-5).
Table 10-5 – Battery-Grade Targets.
Element (ppm) | Run 3 High-Grade Product | Battery-Grade Target |
Mg | 165 | <50 |
Ca | 125 | <50 |
Na | 103 | <180 |
K | 26 | <30 |
B | 36 | <50 |
SO4 | 135 | <375 |
Cl | 33 | <50 |
Li2CO3 (%) | >99.83 | >99.65 |
The process modifications proposed to achieve BG specification were as follows:
● | Increased lithium tenor in softening feed from 1.2% Li to 1.7% Li (as ongoing testwork had indicated that, after liming, 1.7% was achievable without precipitation of lithium). |
● | Additional polishing filtration steps in softening, including candle filtration, to remove fine particles of calcium and magnesium solids. |
● | Ion exchange columns between softening and crystallization, to remove any remaining Ca and Mg in solution. |
● | Particle size control in crystallization by management of recycle stream and implementation of a wet screen. |
The implementation and testing of the circuit modifications necessary to achieve BG specification in the pilot plant was tested in 2021 in pilot plant Runs 5 – 7. The modified process flowsheet is shown in Figure 10-12.

10.2.10.6 Liming 2021 (Run 4)
Liming was performed in Run 4 in March and April of 2021, with 665 m³ of limed brine produced over 33 days. After thickening was shown to be inefficient for liming solids in Run 2 and the GBL testwork, no thickening was performed in Run 4 liming and only filtration was used for solid-liquid separation. Liming was shown to be effective across a broad range of feed concentrations, from 0.4% to 0.8% Li, demonstrating that the process is operationally robust. The limed brine produced by Run 4 liming was returned to the evaporation ponds for evaporation to 1.7% Li.
10.2.10.7 Liming 2021 (Runs 5-7)
Three different softening runs were performed in 2021, all utilizing the 1.7% limed brine from Run 4. The major process changes from 2020 were the implementation of a candle filtration step after the plate-and-frame filter to remove very fine solids and ion exchange columns post-filtration to remove and residual dissolved Ca and Mg. In addition, dilution and reagent addition strategies were investigated to optimize performance and lithium recovery. The findings were:
● | Softening successfully demonstrated using a 1.7 wt.% Li brine feed, while removing Ca and Mg to levels of ~10 mg/l in filtrate. |
● | Dilution of the 1.7 wt.% Li brine to ~1.4 wt.% Li provided significant benefits to circuit operation. The circuit could tolerate operation at a higher pH, with improved robustness of operation (e.g., in the event of Na2CO3 over addition), while maintaining Li recoveries of >97% to liquor. |
● | Addition strategy of reagents is crucial to meet performance specifications: |
● | 2-stage addition of NaOH; first reactor of the circuit and then immediately prior to filtration (filter feed tank or final reactor). The second addition was in the order of 1% stoichiometric addition, applied on an ‘as needed’ to maintain the pH, optimizing Mg removal without significant Li loss. |
● | Negligible effect on Ca rejection when using 2-stage addition of Na2CO3, versus 1-stage addition. 2-stage addition did provide greater control of dosing during piloting, although this is not expected to be as sensitive at larger scale. |
● | Addition of Na2CO3 must be controlled against the Ca content after Mg removal (NaOH addition), instead of the feed brine. This philosophy reduces the risk of overdosing and therefore limiting Li losses to precipitation. |
● | Typical NaOH dosages were between 100–110% (stoichiometric vs. Mg) and Na2CO3 was 104 – 110% (stoichiometric vs. Ca, post NaOH addition). Additions are in line with design expectations. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Run 5 demonstrated effective polishing of softened brine, utilizing 1 µm and 0.2 µm filters connected in series. Cartridge filters were capable of maintaining performance during short periods of high solids content in the feed liquor (filter press filtrate). Results informed the use of ~1 µm and ~0.2 µm industrial cartridge filters in series and duty/standby configuration to manage offline time for cartridge replacement in the industrial plant. |
● | Candle filter (DrM Fundabac) performance was comparable to cartridge filtration, with respect to removal of fines. The findings supported the application of candle filtration at full-scale, while retaining cartridge filtration in a ‘guard’ capacity. The increased capacity of the candle filter also allows for it to better tolerate upset conditions, where increased solids report to the filter press filtrate. |
● | Pre-coating (filter aid) of candle filter cloths for each cycle was not required. Good performance was observed with an initial precoat applied to ‘fresh’ filter cloths. Multiple cycles were performed in the pilot without the need to refresh the filter aid application. Improvements may be observed with cloth selection, further minimizing the use of filter aid. |
● | IX demonstrated in a lead-lag configuration; two columns online in series, one offline for regeneration. Resin used was Lewatit MDS TP 208. |
● | IX columns were operated continuously, removing Ca and Mg from the softened brine (~10 mg/l) to concentrations of <1 mg/l in IX barrens (crystallization feed). Robust operation observed with brine concentrations between 10 – 30 mg/L Ca and Mg, still reduced to <1 mg/L following IX. |
● | The main operational challenge experienced in IX was the passing of fine solids (Ca and Mg containing) through the resin bed after 3 to 4 days of operation. Anticipated breakthrough of soluble Ca/Mg was ~5 days, based on testwork. The solids collected within the IX column were able to be redissolved and Ca/Mg removed from the system through routine regeneration cycles. |
● | Run 7 demonstrated that the softening circuit could be run in tandem with crystallization. |
10.2.10.8 Crystallization 2021 (Runs 5-7)
Three different crystallization runs were conducted in 2021, utilizing the softened brine from each respective softening run. The softened brine was first diluted to ~0.95 wt% Li to match 2020 operations. The diluted softened brine was heated, and sodium carbonate was added to precipitate lithium carbonate, which was recovered by centrifugation with a displacement wash with hot reverse osmosis (RO) water (similar to Run 3). In Run 7, a screen was implemented in the recycle stream for particle size control, and the suitability of a scraped heat exchanger was assessed for maintaining circuit temperature by recirculation of the reactor contents. A product summary of the crystallization runs is in Table 10-6.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The following findings were made regarding the crystallization circuit:
● | Feed to crystallization was diluted to ~0.95 wt.% Li (~10.5 g/l, matching 2020 operations), following testwork recommendations. The dilution is necessary to minimize K and Na reporting to Li2CO3, due to elevated concentrations in the 1.4/1.7 wt.% Li-softened brines. |
● | A ‘flat’ temperature profile was implemented, with the circuit operating at a range 80-86°C, compared to previous targets of 70-86°C. High quality Li2CO3 production in the pilot was consistent with similar conditions in lab testwork. |
● | Circuit residence times of ~4.5 h and ~6 h demonstrated with no change in Li2CO3 quality. |
● | Investigation of 2-stage addition (Tank 1 and 2) vs. 3-stage addition (Tanks 1 – 3) of Na2CO3 resulted in no discernible difference in Li2CO3 product quality. 2-stage addition is to be retained, in line with findings following 2020 piloting (Run 3). |
● | Investigation of recycle ratio to manage crystal size. This informed the industrial plant design to recycle between 20 – 50% solids, to allow for optimization. |
● | Importance of particle size was highlighted in Run 5 and Run 6: |
○ | The formation and settling of Li2CO3 agglomerates within reactors were identified. The settled product (lower tank discharge) was found to be of a poorer quality, with elevated Ca, K and Na – attributed to entrainment of mother liquor. |
○ | The application of internal tank recycling, using both opened and closed impeller centrifugal pumps, ensured the tank contents were homogeneous and minimized agglomeration. With prolonged use, the Li2CO3 reporting to the centrifuge became finer and in turn, difficult to wash on the centrifuge. |
○ | Control of particle size distribution is recommended through techniques such as cut size of cyclones, internal tank recycles, attritioning tanks and screening of slurry. Careful monitoring of particle size is required to balance between the formation of agglomerates (occlusion of mother liquor) and a particle size which is too fine (detrimental to washability). |
● | Upgrade from technical to BG Li2CO3 in 2021 piloting activities. Greater than 77% and 85% of product in Run 5 and 6 respectively met or exceeded BG targets with respect to elemental impurities. In Run 7, 95% of the product achieved BG. The remaining product was predominately technical grade, with the decrease in quality largely attributed to poor washing characteristics on the centrifuge. |

Further observations were made in Run 7 regarding the new additions of a screen and scraped heat exchanger:
● | Use of screen technology successfully produced a Li2CO3 slurry of a target particle size. |
● | At 100 µm, ~1% of Li2CO3 solids reported to oversize. At 63 µm the use of ‘repulp’ stages was identified as critical to manage rate of dewatering, with between 3 – 4% Li2CO3 solids reporting to oversize (unoptimized). Without the use of these features the oversize fraction increased to 10 – 20%. |
● | Screening at 100 µm, critical impurities (i.e., Ca and Mg) were rejected via the oversize stream, confirmed via solids analysis. This trend was not evident when screening at 63 µm, indicating high impurity agglomerates were primarily >100 µm in size. |
● | The scraped heat exchanger was suitable for both crystallization brine pre-heating and circuit heating duties, with effective scale management. Consideration is needed for materials of selection to avoid product contamination. Steam is the preferred heating media, compared to hot RO water. Existing steam capacity to be reviewed and considered in supply package. |
10.3 Products and Recoveries
10.3.1 Process Losses and Recovery
Recovery and losses for Sal de Vida have been based on test work results and process modelling and validated by independent third-party experts. A breakdown of the losses and overall recovery for the process is shown in Table 10-7. The final lithium recovery for the process is estimated as 70%.
Because of the process design and utilization of recycle streams, lithium is only lost through three avenues: entrainment of pond brine in precipitated salts, leakage of pond brine (including permeation, liner punctures and other brine losses) and entrained liquor in the cake of solids from the liming filter. Most of the lithium remaining in the mother liquor from the crystallization process is recycled to the ponds (see Sections 14.1 and 14.2 for more information on recycle and waste streams).

10.3.2 Products
The only product planned for sale from SDV is lithium carbonate, expected to be 80% battery grade and 20% of technical grade. Piloting indicates that a distribution of 95% battery grade and 5% technical grade will be achievable, allowing flexibility to adapt to market demands (Section 10.2.10). Results from Pilot Plan Run 7 are displayed in Table 10-8.

10.4.2 Variations in Process
A wide range of lithium concentrations from 6,400 mg/l to 8,200 mg/l Li was tested during the liming pilot run in 2020. This run utilized brine evaporated on site from Well SVWP17_21. Results from the pilot run did not indicate any performance issues relating to operating the liming plant within this range of lithium feed concentrations. Sufficient flexibility is incorporated in the lime system to cope with seasonal fluctuations in key brine components such as sulphate.
Flexibility in the liming system can be achieved by varying the lime addition to achieve the desired magnesium removal, even with a varying feed magnesium concentration as demonstrated in the pilot plant. The liming process also removes sufficient sulphate and boron such that these elements do not pose a problem downstream in the process plant anywhere in the wide range of brine concentrations tested.
The large residence time of the pond system can also serve to ’smooth out’ temporary deviations, as otherwise out-of-spec brine will mix with a large volume of normal in-spec brine, bringing it back into specification.
The softening stage also contains flexibility in case of deviations in magnesium and calcium. Dosage of caustic and sodium carbonate can be varied to achieve the desired magnesium and calcium removal without significant loss of lithium, in accordance with the variation in the feed to the process plant. The candle filter and ion exchange circuits at the end of the softening stage can remove small amounts of calcium and magnesium remaining after press filtration as solutes or fine solids, allowing the concentrations to be reduced to near zero (<1 mg/l). Two softened brine storage tanks in duty/standby configuration at the end of the softening circuit will allow for confirmation that the brine is on-spec before advancing to the crystallization circuit. If it is not, it can be transferred to a third tank for batch re-treatment and reintroduction to the softening circuit, preventing any off-spec feed brine crystallization.
For more information on the design of the process plant, see Section 14.2.

SEC Technical Report Summary
10.5 Deleterious Elements
There are two major sources other than brine feed of deleterious elements that may be introduced into the process: impurities from reagents and metallic iron from plant equipment.
Sodium carbonate is of particular concern as insoluble deleterious elements will report to the product, impacting its quality. In order to mitigate this risk, a series of steps have been taken to ensure that the sodium carbonate being utilized in the crystallization circuit is free from these impurities. Two manual cartridge filters in a duty/standby configuration are used to ensure that insoluble particles are captured and removed from the process before being fed into the crystallization circuit. An IX circuit will also be used to remove any trace divalent ions that may be present in the sodium carbonate solution.
Another source of deleterious elements introduced into the system is iron from plant equipment such as pumps or agitators. Strategically placed magnets within the process are used to capture and remove these impurities.
10.6 Conclusion
It is the opinion of the employee of Gunn Metallurgy that the mineral processing and metallurgical testing data is adequate for the purposes used in the technical report summary. The test work conducted is in concept appropriate and well-conceived and the described process design is reasonable and implementable. The process concept is largely standard and has been previously proven to produce similar products.

11. Mineral Resource Estimates
This section contains forward-looking information related to Mineral Resource estimates for the Sal de Vida Project. The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions set forth in this section including geological and brine grade interpretations, as well as controls and assumptions related to establishing reasonable prospects for economic extraction.
11.1 Introduction
The deposit type is a brine aquifer within a salar basin. Brine deposits differ from solid phase industrial mineral deposits by virtue of their fluid (dynamic) nature. Because of the mobility the brines, the flow regimes, and other factors such as the hydraulic properties of the aquifer material are just as important as the chemical constituents of the brine in establishing a Brine Resource estimate. The essential elements for Resource Estimation in brines include the determination of drainable porosity and brine concentration through drilling and sampling.
11.2 Definition of Hydrogeologic Units
Results of diamond drilling indicate that basin-fill deposits in Salar del Hombre Muerto can be divided into hydrogeologic units that are dominated by five lithologies, all of which have been sampled and analyzed for drainable porosity. The micaceous schist was assumed to have a negligible drainable porosity, therefore only 5 units were used to estimate the resource. Predominant lithology, number of analyses and statistical parameters for drainable porosity of these units are given in Table 11-1.
Table 11-1 – Summary of Drainable Porosity.
Predominant Lithology of Conceptual Hydrogeologic Unit | Number of Analyses | Mean Drainable Porosity | Median Drainable Porosity | Standard Deviation |
Unit 1: Clay | 9 | 0.034 | 0.026 | 0.024 |
Unit 2: Halite, gypsum or other evaporates | 75 | 0.041 | 0.030 | 0.042 |
Unit 3: Silt and sandy silt | 11 | 0.049 | 0.048 | 0.016 |
Unit 4: Sand and silty sand | 25 | 0.131 | 0.146 | 0.086 |
Unit 5: Travertine, tuff and dacitic gravel | 1 | 0.042 | 0.042 | --- |
Each borehole was divided into hydrogeologic units using the five predominant lithologies given above. Drainable porosity values for each hydrogeologic unit within a single polygon were computed by averaging the available drainable porosity data from within the hydrogeologic unit at the polygon borehole. For a few hydrogeologic units, within some polygon blocks, no porosity data were available. For these units, drainable porosity was estimated and assigned from laboratory analyses of similar lithologies in other Hombre Muerto boreholes, or conservative drainable porosity values were estimated from published values (Johnson, 1967), and assigned based on lithology, as follows in Table 11-2.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Table 11-2 – Assigned Drainable Porosity Values.
Predominant Lithology of Hydrogeologic Unit | Assigned Drainable Porosity |
Clay | 0.02 |
Halite, gypsum, or other evaporites | 0.04 |
Silt and sandy or clayey silt, and siltstone | 0.05 |
Sand, silty sand, and sandstone (>50% sand) | 0.10 |
Travertine, tuff, and dacitic gravel | 0.15 |
For those hydrogeologic units within an individual borehole where no chemistry data are available, the analyses from the nearest samples both above and below the unit were averaged and the average value was applied to the entire unit.
11.3 Mineral Resource Methodology
The following is an abbreviated summary of the utilized methodology and resource calculations which have been applied in industry for other lithium brine resource estimates. To estimate the total amount of lithium in the brine, the basin was first sectioned into polygons based on location of exploration drilling. Each polygon block contained one diamond drill exploration hole or exploration well. Boundaries between polygon blocks are generally equidistant from diamond drill holes, and the Houston et al., 2011 methodology was considered when determining the area of the polygons. For most polygon blocks, outer boundaries are the same as basin boundaries, as discussed above.
Within each polygon shown on the surface, the subsurface lithological column was separated into hydrogeologic units which vary with depth based on the lithologic logs and other available field information such as geophysics. Each interval of the individual polygons was given a representative value for drainable porosity and average lithium content based on laboratory analyses of samples collected during exploration drilling. The total depth of each polygon was based on the total depth of each borehole. The resource was estimated by summing the aquifer volume multiplied by drainable porosity and lithium grade for each interval of the individual polygons and resource category.

11.4 Mineral Resource Classification
Figure 11-1 is a location map for Sal de Vida Project showing Measured, Indicated, and Inferred lithium resource polygons. The total area of polygon blocks used for resource calculations is about 146 km2, not including Inferred Resource in the southeast part of the concession area, which is about 14.9 km2.
Figure 11-1 – Location Map Showing Measured, Indicated, and Inferred Lithium Resources.
To classify a polygon as Measured or Indicated, the following factors were considered:
● | Level of understanding and reliability of the basin stratigraphy. |
● | Level of understanding of the local hydrogeologic characteristics of the aquifer system. |
● | Density of drilling and testing in the salar and general uniformity of results within an area. |
● | Available pumping test and historical production information. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Areas were designated as Measured where additional information exists on the physical brine aquifer parameters that were derived from pumping tests (e.g., transmissivity, aquifer thickness, hydraulic conductivity, and storativity), or where the stratigraphic conditions allow more confident understanding of the units (e.g., bedding, induration, lateral continuity). In the Measured status area, several aquifer tests have been conducted in the basin and support an increased understanding of the hydrogeologic conditions and support the idea that the brine can be pumped from production wells at sufficiently large rates to support long-term economic production of brine rich in lithium. In the eastern-central portion of the mine properties, production has occurred since 2022 which further supports the Measured category. Based on reasonable agreement with aquifer test results and our conceptual model of these areas, there is sufficient understanding of the areas with respect to both stratigraphy and aquifer properties to be able to characterize these as Measured.
Areas were designated as Indicated where confidence is high in the interpolation of units between wells. Although there are several areas where reasonable stratigraphic interpolation can be made between boreholes, the level of confidence drops extrapolating outward from the well where there are either: 1) no other nearby wells, or 2) where the geologic and hydrogeologic nature of basin boundaries is less uncertain based on available field information. Because some of the extractable brine fluid resource will move between units to production pumping centers, a more exact interpretation of the lithologic units at this stage of the estimation process was not believed to be required and the level of accuracy at the scale of data on record is believed acceptable for the Indicated areas.
The areas that were categorized as Inferred include areas where no drilling or testing was conducted but are believed to have resource in them based on results for nearby areas. For this report, although relatively common in the industry, no Inferred Resource was estimated for areas below depths drilled, even when geophysical results suggest that a brine-rich reservoir exists beneath the well.
11.5 Cut-Off Grade
A lithium cut-off grade of 300 mg/l was conservatively utilized based on a breakeven cut-off grade for a projected lithium carbonate equivalent price of US$20,000 per tonne (US$25,000 with a revenue factor of 0.75) over the entirety of the LOM. Considering the economic value of the brine against production costs, the employees of Montgomery & Associates consider the economic assumptions appropriate for the 300 mg/l cut-off grade assignment to account for potential uncertainties in the projected price as well as processing considerations (see Chapter 10). Furthermore, the assigned 300 mg/l cut-off grade is consistent with other lithium brine projects of the same study level which use a similar processing method, and the grade-tonnage curve of Figure 11-2 indicates that the overall tonnage of Measured, Indicated, and Inferred does not vary materially under a cut-off grade of 500 mg/l.
The average lithium grade of the measured and indicated resources corresponds to 742 mg/l and represents the flux-weighted composite brine collected as brine is routed to the evaporation ponds. Extracted grades at individual production wells and the average measured and indicated resources concentration are well above the 300 mg/l cut-off grade, demonstrating that there are reasonable prospects for economic extraction.

The estimated economic cutoff grade utilized for resource reporting purposes is 300 mg/l lithium, based on the following formula and inputs:
The cut-off grade was elevated to 300 mg/l to increase margin and de-risk the uncertainties around price fluctuations. The cut-off grade is used to determine whether the brine pumped will generate a profit after paying for costs across the value chain.

Mineral Resources were estimated on an in-situ basis. Currently, the employees of Montgomery & Associates do not know of any environmental, legal, title, taxation, socio-economic, marketing, political, or other factors that would materially affect the current Resource estimate.
11.7 Uncertainty
Factors that may affect the Mineral Resource estimate include:
● | Locations of aquifer boundaries, and or shallower than anticipated bedrock near hard rock area. |
● | Lateral continuity of key aquifer zones. |
● | Presence of fresh and brackish water that have the potential to dilute the brine in the wellfield area. |
● | The assumed uniformity of average aquifer parameters within specific aquifer units. |
While these uncertainties exist, the employees of Montgomery & Associates conservatively assigned resource categories in a manner aligned with industry practices for lithium brine projects. To support an upgrade of the resource categories, the following factors are key to reduce uncertainty: the level of understanding and reliability of the basin stratigraphy; the level of understanding of the local hydrogeologic characteristics of the aquifer system; the density of drilling and testing in the salar and general uniformity of results within an area.
11.8 Conclusion
In the experience of the employees of Montgomery & Associates with groundwater and brine extraction from clastic and salar basins, a realistic assumption is that potentially 30% - 40% of the Resource (inclusive of Mineral Reserve) should be considered as a reasonable estimate of long-term, total recoverable brine based on the existing information. Recovering more than 50% of the brine in storage may not be feasible. To completely drain the basin would require increasingly large numbers of production wells and would increase the amount of fresh water moving into the brine aquifer. Therefore, 100% drainage is not technically or economically feasible for a project such as Sal de Vida. That said, the employees of Montgomery & Associates believe that there is substantial upside potential for increasing both the Resource categories (i.e., changing Inferred to Indicated or Measured, and/or changing Indicated to Measured), and also by increasing the total volume of the Resource by drilling in unexplored areas, and also by drilling deeper. It has been demonstrated in several parts of the basin that the lithium brine aquifer extends to depths greater than currently used to estimate the Resource.

12. Mineral Reserves Estimates
This section contains forward-looking information related to Mineral Reserve estimates for the Sal de Vida Project. The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions set forth in this section.
The methodology used in this section consider modifying factors for converting Mineral Resources to Mineral Reserves, including allowable well field pumping and dilution of brine during pumping, among others.
12.1 Numerical Model
Given that the economic reserve is estimated based on physical pumping of the brine that flows during wellfield pumping, a calibrated numerical model which simulates groundwater flow and solute transport was used to estimate the Mineral Reserve.
12.1.1 Numerical Model Design
The 3D numerical model was constructed using the Groundwater Vistas interface Version 7 (Environmental Simulations Incorporated, ESI) software and was simulated using the control volume finite difference code Modflow USG-Transport (Panday, 2019). Modflow-USG was selected because of its advanced capabilities that include its local grid refinement option, its numerical robustness using the Newton Raphson formulation (Hunt and Feinstein, 2005) and upstream weighting, as well as its ability to simulate variable-density flow and transport with advection and dispersion.
The active model domain encompasses the clastic sediments and evaporite deposits that comprise the Salar del Hombre Muerto as well as the upgradient alluvial deposits and the Río de los Patos sub-basin. The extent of the active model domain, which covers an area of about 383 km2, is shown in Figure 12-1.
The active model domain includes the salar and outlying areas of the basin; the domain was designed to be extensive enough to adequately incorporate zones of recharge associated with the Río de los Patos and minimize the influence of applied boundary conditions on the production well simulation. The base of the active model domain was set based on current interpretation of depth to basement, considering the location of the Tertiary basement in the western part of the model and the Precambrian basement in the eastern part of the model.
Local layers of clays based in stratigraphy information from drilled wells in the east zone of the basin (projected East Wellfield) was also incorporated in the model.

SEC Technical Report Summary
12.1.2 Grid Specifics
The 3D model domain was divided into a grid of node-centered, rectangular prisms commonly referred to as cells. Using the quadtree feature of Modflow-USG, cells with small lateral dimensions (maximum refinement of 3.125 m) were assigned in areas of interest such as pumping well locations, while larger elements (200 m) were assigned in areas with little available information or in zones farthest from the areas of interest. Vertically, the domain was divided into 12 model layers based on the amount of exploration data with depth. Each layer consists of a variable number of cells depending on the presence of low permeability bedrock or lack of exploration data at depth. Model layer thicknesses range from 10 – 60 m, and each layer, other than the basal layer, was of a constant thickness. The lower layer was set to be thicker because there is less information in the deeper portions.

12.1.3 Density Driven Flow and Transport
The density-driven flow (DDF) package, coupled with block-centered transport (BCT), was utilized to simulate variable-density flow and transport. The modeled area included zones of mixing where incoming recharge of lower density water enters the salar but discharges to the surface due to differences with the density of the brine in the aquifer. Thus, the numerical model was designed to simulate changes in solute concentration during pumping that are likely to occur due to influx of fresh water to the future production wells.
Total dissolved solids (TDS) in the brine and freshwater were defined as the only solute component in the numerical model to represent the concentration–water density relationship and freshwater–brine interface. The DDF package assumed a linear relationship between TDS concentrations and water density. As can be seen in Figure 12-2, there is a strong positive linear relationship between the density of the brine and the amount of TDS.
Figure 12-2 – Relationship Between Total Dissolved Solids and Density for Groundwater (Brine and Freshwater) Samples.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | A freshwater density of 1,000 kg/m3 for a TDS concentration of 0 kg/m3. |
● | A water density of 1,210 kg/m3 for a TDS concentration of 329 kg/m3. |
Initial concentrations were defined based on laboratory measured values from samples collected during exploration drilling and were then interpolated to create an initial distribution for the model. During the steady-state (long-term transient) calibration, the hydraulic head solution was cycled until an approximate equilibrium was achieved with the simulated concentrations (which are based on the initial concentrations from measured samples). The concentration solution of the steady-state model was subsequently used as initial conditions for the transient calibration and simulation.
The linear relationships with TDS were used to estimate concentrations in pumped brine from the wellfield simulation. The evapotranspiration (ET) concentration factor was set to 0, signifying that TDS mass did not leave the system due to evapotranspiration.
12.1.4 Numerical Model Boundary Conditions
Groundwater outflow from the basin occurs via evaporation from dry and moist salar surfaces in addition to evapotranspiration from vegetation and from open water evaporation surface water bodies (Laguna Verde). Groundwater movement is generally from the margins of the salar, where mountain front recharge enters the model domain as groundwater underflow, toward the center of the salar. Tertiary sediment outcrops along the west and north basin boundaries conceptually approximate low to no-flow boundaries which are expected to contribute negligible brine to the basin-fill deposit in the salar. Metamorphic and crystalline bedrock along the east basin margin is expected to have low hydraulic conductivity and was assumed to represent a no-flow groundwater boundary during extraction of brine from basin-fill deposit aquifers by pumping wells.
The numerical model boundary conditions were designed to be consistent with the conceptual baseline water balance (Montgomery & Associates, 2020 and Chapter 7), assuming average natural long-term hydrologic conditions, where inflows (recharge from precipitation and snowmelt) are approximately equivalent to outflows (evaporative discharge) and no production pumping occurs in the salar. As indicated in Chapter 7, the conceptual water balance was implemented by following the equation:
Long-term evaporation rate estimates of 850 l/s, 1,500 l/s and 2,300 l/s for low, medium, and high evaporation rate scenarios, respectively, were obtained, using remote sensing combined with an evaporation rate characterization based on local meteorological data. The higher evaporation estimate is slightly too large compared to the upper bound of the precipitation recharge estimate (2,210 l/s). In addition, the lower bound of the precipitation recharge estimate (550 l/s) is too low compared to the lower evaporation estimate (~850 l/s) and is not believed to be realistic. The recharge estimate for the east sub-basin of the Salar del Hombre Muerto is believed to range from 850 – 2,210 l/s based on the results of intersecting the evaporation and precipitation recharge ranges. Within this range, the current best estimate for a recharge to the salar is 1,500 l/s based on the calculated medium evaporation discharge, which approximately corresponds to 13.1% of total volumetric precipitation (including snowmelt) estimated for the basin. The current best estimate is considered to be that obtained from the evaporation estimate, which is specifically the medium evaporation rate scenario at 1,500 l/s. Direct precipitation recharge was applied over all areas of the active model domain, and a dissolved TDS concentration of 1.5 kg/m3 was assumed for inflow at the recharge cells.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The Río de los Patos was simulated using a river (RIV) package, which simulates the interaction between groundwater and surface water. For the purposes of the Brine Reserve estimate, the river behavior in the far upper region of the Río de los Patos sub-basin is not considered a key factor because it ultimately translates to a net amount of water moving toward the salar. Similar to the simulated recharge, modeled TDS concentrations in the river water were set to 1.5 kg/m3.
The general head boundary (GHB) condition represents the connection between groundwater in the active model domain and the immediate area of Laguna Catal, a natural zone of discharge. The GHB stage was set to equal the average elevation of the surface water in Laguna Catal (3,965 m), and the conductance was specified based on the distance between Laguna Catal and the southwest limit of the active domain as well as the hydraulic conductivity and saturated cell volume. TDS concentrations of potential inflow to the domain from those cells were conservatively set to 0 mg/l to assume maximum potential dilution in the future. The specified flux (WEL) cells were assigned in the northwest portion of the salar to represent a small outflow of 10 m3/d (Montgomery & Associates, 2018).
The evapotranspiration (EVT) package was used in cells of the salar to simulate evaporation from three distinct zones including soil, vegetation, and open water. The zone representing open water evaporation was specifically applied in the Laguna Verde area. The EVT package simulated a linear change in evaporation from the specified extinction depth to land surface. The extinction depth is defined as the depth below which groundwater does not evaporate. The evaporation rates varied according to the zone, and extinction depths were set based on the type of soil and measured water density trends.
12.1.5 Modeled Hydraulic Properties
Hydraulic properties of the numerical model include hydraulic conductivity in the three cardinal directions (Kx, Ky, and Kz), specific storage (Ss), and specific yield (Sy). These parameters were assigned based on the hydrogeological unit and were adjusted throughout the calibration in specific zones according to the conceptual range. The range of assigned hydraulic properties is generally consistent with expected values in this environment of deposition as well as the calculated values and trends observed from on-site aquifer tests (Montgomery & Associates, 2013; 2018). Also, results from hydraulic testing in recently drilled production wells were used as a reference for calibration in the east zone of the model. Specific hydraulics values were also assigned to local clay layers in this zone of the model, based on stratigraphy information from drilled wells. Table 12-1 includes the calibrated hydraulic parameters; note that the mica schist was not modeled due to its expected low permeability and representation via a no-flow boundary condition.

SEC Technical Report Summary
Table 12-1 – Calibrated Hydraulic Parameter Ranges7
Hydrogeological Unit | Maximum Horizontal Hydraulic Conductivity (m/d) | Minimum Horizontal Hydraulic Conductivity (m/d) | Ratio of Vertical to Horizontal Hydraulic Conductivity (Kz/Kh) | Specific Storage (1/m) |
Mixed evaporites a | 0.16 | 0.1 | 0.01 to 0.1 | 5.00E-05 |
Upper salar sediments b | 2.3 | 0.5 | 0.01 | 0.0001 to 5e-005 |
Volcaniclastics | 1.1 | 0.8 | 0.5 to 1 | 5.00E-05 |
Lower sediments c | 2.3 | 0.01 | 0.01 to 1 | 5.00E-05 |
Travertine | 2 | 2 | 0.2 | 5.00E-05 |
Alluvial sediments | 100 | 1 | 0.1 to 1 | 5e-005 to 0.0001 |
Without evidence of horizontal anisotropy from testing results, Kx was considered equal to Ky, and the horizontal hydraulic conductivity is termed radial hydraulic conductivity (Kr). Vertical anisotropy (Kz/Kr) was applied in certain zones throughout the calibration in accordance with the geological unit and form of deposition. Where anisotropy was incorporated for calibration purposes, the ratios of Kz/Kr also consider estimates from literature values for similar regimes (e.g., Freeze and Cherry, 1979 and Mason and Kipp, 1998).
The range of specific storage assigned in the model is based on the type of lithology and estimates from literature (Batu, 1998). The lower end of the range is near the compressibility of water, which indicates a rigid, low porosity material with small compressibility of the rock mass, and the upper end is indicative of a higher porosity and larger compressibility of the rock mass. Assigned values of specific yield considered laboratory testing results (Montgomery & Associates, 2018) and used values in comparable geological units of similar salars.
Effective porosity was generally assumed to be equivalent to specific yield and varies spatially depending on the lithology. For simulating the transport of dissolved TDS, assigned values of dispersivity correspond to 20 m for longitudinal dispersivity, 2 m for transverse dispersivity, and 0.2 m for vertical dispersivity. These values and ratios are generally consistent with those determined from controlled field experiments (Hess et al., 2002). Molecular diffusion was not included in the numerical model because it is considered to be negligible in large-scale regional models.

12.2 Numerical Model Calibration
Prior to the simulation of future brine production, the numerical model was calibrated to verify assigned model parameters such as hydraulic conductivity and storage. International modelling guides were used to evaluate the quality of the calibration (Reilly and Harbaugh, 2004; Anderson et al., 2015).
12.2.1 Steady-State Calibration
The numerical groundwater model was initially calibrated to average, steady-state conditions using the available average on-site field measurements of water levels in observation wells. The numerical model simulates variable-density flow and transport, therefore a “long-term transient” model, with constant stresses (used interchangeably here with ¨steady-state model¨), was simulated over a sufficiently long time period to approach equilibrium steady-state conditions. The hydraulic head and concentration solutions were then cycled until the change in storage was sufficiently low (approximately 0.1% of the average total inflow and outflow). Although the spatial variations in hydraulic head indicate that groundwater flow occurs predominantly from the south to the north, the change in head over time at the end of the long-term transient simulation is negligible. The calibrated solution in steady state is considered acceptable with all hydraulic head residuals (observed value minus simulated value) within 7 m, a mean residual of -0.44 m, and a scaled RMS of approximately 3%. Figure 12-3 shows the simulated piezometric surface in layer one and indicates that groundwater flow occurs from the south (higher elevation alluvial sub-basin) towards the north (lower elevation salar).

SEC Technical Report Summary
12.2.2 Transient Calibration
Following the steady-state calibration, a transient model calibration was conducted to better represent the aquifer’s response to pumping. The head and concentration results from the steady-state model were used as initial conditions for two separate transient calibrations using water level drawdown data from long-term pumping tests conducted at SVWW11-10 and SVWP17-21. Although these two transient calibrations were local, the modelled aquifer parameter zones extend beyond the immediate pumping areas (e.g., the volcaniclastic hydrogeological unit), so a larger area of the numerical model was also improved as a result of the transient calibration:
● | Observed and simulated hydrographs of observation wells during the SVWW11-10 test in the proposed Southwest wellfield closely agree and show that the model adequately represents the aquifer’s response to pumping (i.e., drawdown) at the distinct observation wells. Other calibration parameters include a scaled RMS of approximately 6% and absolute residual mean of about 0.1 m, which is considered acceptable. | |
● | Observed and simulated hydrographs of observation wells during the SVWP17-21 test in the proposed East Wellfield are closely matched and show that the model is appropriately representing the aquifer response to pumping at the distinct observation wells. Other calibration parameters include a low scaled RMS of approximately 3% and absolute residual mean of under 0.2 m, which is considered acceptable. |
12.2.3 Model Verification
Following the historical calibration period described above, simulated production concentrations were compared with real extracted concentrations from January to early March 2023. During this time, production from all the following pumping wells occurred in the East Wellfield: SVWP21-01, SVWP21-02, SVWP21-03, SVWP21-05, SVWP21-06, and SVWP21-07. The average extracted lithium concentration from these pumping wells was approximately 856 mg/l, while the flux-weighted average concentration of those production wells in the numerical model during the first three months of projected pumping (see Section 12.3; the simulated pumping is similar to real pumping during January to March 2023) corresponds to 803 mg/l. Thus, the model slightly underpredicts extracted concentrations in the Stage I East Wellfield by 6%, which is considered acceptable as it is conservative in terms of the overall extracted mass.
12.3 Predictive Simulation

The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions set forth in this section.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Following the steady-state and transient calibrations, a predictive simulation was conducted with future brine extraction from the east and southwest portions of the mine concessions. The wellfields and simulated production wells are shown on Figure 12-4. Projected production locations were based on the Measured Resource zones and were configured to reduce well interference during pumping. Modifying factors associated with the conversion of Measured and Indicated Mineral Resources to Mineral Reserves were considered, including the production wellfield design and efficiency (e.g., location and screen) and potential dilution from pumping.
Figure 12-4 – Simulated Production Well Locations.
Using the predictive model results, the cumulative mass of lithium produced was estimated. The results were then multiplied by a conversion factor of 5.322785 (based on molecular weight to compute LCE). The resulting values from each production well were then summed up for each production year to determine the predicted annual LCE production.

SEC Technical Report Summary
12.3.1 Projected Pumping
The Stage 1 pumping from the East Wellfield is expected to produce 15,000 t of lithium carbonate equivalent (LCE) per year, while the Stage 2 Expansion will generate a total of 45,000 t of LCE per year with active pumping from both wellfields (assuming processing losses). Due to seasonal changes in pond evaporation and maintaining the lithium carbonate target for each stage, the modeled production pumping rates are time-variable on both a monthly and annual timeframe (Table 12-2). Rates were varied spatially to optimize the extracted mass and reduce dilution and drawdown.

The expected LOM is 40 years, and pumping is anticipated to proceed as follows:
● | Stage 1 (8 wells in the East Wellfield) is assumed to start pumping at day 1 and continues for 2 years. | |
● | Stage 2 Expansion (9 wells in the Southwest wellfield and 15 total wells in the East) is assumed to begin at the start of Year 3 and continues pumping for 38 years. |
Initial conditions for flow and transport were defined from the steady-state model solution and in the case of the Southwest Wellfield, each production well was screened from 120 m bls (layer 7) to 180 m bls (layer 9). In the case of the Stage I East Wellfield and Stage 2 expansion in the east, each already installed was screened based on its own construction and well schematics. For the projected wells in the east, their screens vary between 120 m (Layer 7) and 200 m (Layer 10). Results of the 40-year pumping simulation were analyzed to estimate the extracted lithium grade as a function of time and estimated lithium reserve.

12.3.2 Conversion of Simulated Total Dissolved Solids to Lithium
The numerical groundwater model simulates lithium concentrations based on linear relationships developed from measured values of lithium and TDS. Additionally, the groundwater model simulates density-dependent flow based on measured relationships between fluid density and TDS. These relationships were developed for each wellfield by establishing a correlation between these components using the results of the chemical analyses for samples collected during the initial pumping tests and for the depth-specific samples collected from the core holes in the wellfield areas.
The linear equation used to convert model results of simulated TDS content for the East Wellfield to concentrations of lithium is as follows:
The following linear equation (valid for TDS>20 kg/m3) was used for converting model results of simulated TDS (kg/m3) content for the Southwest wellfield to concentrations of lithium:
12.3.3 Deleterious Elements
Together with lithium, the pumped brine is projected to contain significant quantities of potassium, magnesium, calcium, sulphate, and to a lesser degree, boron. These constituents must be removed from the brine to enable effective retrieval of the lithium. The specific design and operation of the industrial processes for the removal of magnesium, calcium, sulphate, and boron are detailed in Section 10 of this Report.
The numerical groundwater flow model simulates concentrations for these deleterious elements based on linear relationships between their measured values and measured values of TDS. These relationships were developed for each wellfield by establishing a correlation between these components using data from samples collected during pumping tests and from depth-specific core hole samples in the wellfield areas.
The following linear equations (valid for TDS>50 kg/m3) are used to convert projected TDS (kg/m3) content for the Southwest Wellfield to concentrations of magnesium, sulphate, and boron:

The linear equations used to convert projected TDS (kg/m3) content for the East Wellfield to concentrations of magnesium, sulphate, and boron (valid for TDS>50 kg/m3) are as follows:
Because calcium shows no clear correlation to TDS, there is a low-level confidence using the best-fit equation to predict calcium concentrations based on TDS content projected by the numerical model.
For each wellfield, the dilution effects of downward and lateral migration of fresh/brackish water results in decreased TDS concentrations during sustained pumping, and thus the decrease of other solute concentrations.
12.3.4 Mineral Reserves
12.3.4.1 | Conversion from Brine Resources to Brine Reserves |
The Mineral Resource was estimated based on key input parameters of drainable porosity and lithium grade (Chapter 11). Because a lithium brine is a fluid resource and moves within the aquifer, traditional mining methods of estimating a Brine Reserve need to also consider aquifer mechanics associated with production wellfield pumping, and additional aquifer hydraulic properties are required to estimate the Brine Reserve.
The industry-accepted method for simulating removal of aquifer fluid (fresh water or brine) is to use a numerical groundwater flow model to simulate wellfield pumping. The model can be used to estimate water level drawdown associated with pumping (local and regional) and also determine maximum pumping rates, sustainability of wellfield pumping, and in the case of modelling lithium brines, the average lithium grade of the brine over time. Polygonal estimates or 3D block models do not have the capability of doing this type of simulation.
Similar to the Resource methodology, the numerical model used to estimate the Brine Reserve for this Project considers the conceptual hydrogeological model (hydrogeologic units, parameters, and chemistry) determined during the Brine Resource estimation, and it was used to construct the framework of the numerical groundwater flow model. In addition to these initial parameters, aquifer boundary conditions, basin recharge and discharge, estimates, hydraulic conductivity and storativity obtained from aquifer testing, and other parameters were included in construction of the numerical model. Finally, the model was calibrated against data obtained in the field to improve reliability of the simulations.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The groundwater model simulates concentrations of TDS, which are used to derive concentrations of lithium by linear relationships developed for each wellfield. It is assumed that the relationship between TDS and lithium content is constant during 40-year period of brine production from the East and Southwest Wellfields. In this manner, the concentrations of lithium on model projections of TDS in the brine produced from pumping wells in each production wellfield are estimated.
Using the numerical groundwater flow model projections, total lithium to be extracted from the proposed production wells was calculated for a total period of 40 years, considering the two stages of the Project, and considering that East Wellfield will be pumping for 40 years, and the Stage 2 Expansion will be active for 38 years (starting year 3). Projected production wells were placed in Measured Resource zones. The model projections used to determine the Brine Reserve indicate that the proposed wellfields should be able to produce a reliable quantity of brine at an average annual rate of approximately 315 l/s in the case of the East Wellfield and about 191 l/s in the case of Southwest. The average grade at start-up calculated from the initial model simulations used to estimate the Brine Reserve is expected to be about 805 mg/l of lithium in the East Wellfield) and 815 mg/l in the Southwest Wellfield; average final grade after 40 years of pumping is projected to be approximately 750 mg/l of lithium (considering all wellfields). Depending on how the wellfields are ultimately operated, these rates and grades may be different.
Using the groundwater model, the average TDS content of brine was estimated for each pumping cycle for each wellfield. After estimating the total lithium content for each time step and summing the amounts of lithium projected to be pumped during those time steps.
Total mass values in 1,000-kilogram units (tonnes) of lithium were then converted to LCE units. Therefore, the amount of lithium in the brine supplied to the ponds in 40 years of pumping are estimated to be about 2.48 Mt LCE. Modeling results indicate that during the 40-year pumping period, brine will be diluted by fresh and brackish water, so the pumping rates increase slightly with time to meet the anticipated LCE tonnes per year for each wellfield.

(5) | The cut-off grade used to report Sal de Vida Mineral Resources and Mineral Reserves is 300 mg/l. |
12.3.4.3 | Process Recovery Factors |
During the evaporation and concentration process of the brine, there will be anticipated losses of lithium. Based on the Chapter 10 breakdown of recoveries and consideration of deleterious element concentrations, the amount of recoverable lithium from the ponds and plant is calculated to be 70% of the total brine supplied to the ponds. This applies to the current processing method which may be subject to improvements at a later date.
Figure 12-5 shows the yearly reserve for total production (both the Stage I and Stage 2 Expansion) as a saleable product, considering all process recovery factors of the ponds and plant. As can be seen, the production plan of 15,000 LCE per year for Stage I and 45,000 LCE per year for Stage 2 is met.

12.3.4.4 | Mineral Reserve Classification |
The Mineral Reserve was classified according to industry standards for brine projects, as well as the confidence of the numerical model predictions and potential factors that could affect the estimation. The projected well locations were also located in Measured Resource zones, and a majority of the extracted mass is sourced from Measured Resources. The employees of Montgomery & Associates believe that the Proven and Probable Mineral Reserves were adequately categorized, as described below:
● | Proven Reserves were specified for the first 7 years of operations (years 1-7 in the East Wellfield (Stage 1) and years 3-9 in the Stage 2 Expansion Period) given that short-term results have higher confidence due to the current model calibration and also the initial portion of the projected LOM has higher confidence due to less expected short-term changes in extraction, water balance components, and hydraulic parameters. | |
● | Probable Reserves were conservatively assigned after 7 years of operation (years 8-40 in the East Wellfield and years 10-40 in the Southwest Wellfield (Stage 2)) because the numerical model will be recalibrated and improved in the future due to potential changes in neighboring extraction, water balance components, and hydraulic parameters. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
12.3.4.5 | Cut-Off Grade |
A lithium cut-off grade of 300 mg/l was conservatively utilized based on a cut-off grade for a projected lithium carbonate equivalent price of US$20,000 per tonne over the entirety of the LOM. The employees of Montgomery & Associates consider the economic assumptions appropriate for the 300 mg/l cut-off grade assignment to account for processing considerations (see Chapter 10), and the assigned 300 mg/l cut-off grade is consistent with other lithium brine projects of the same study level which use a similar processing method.
The cut-off grade is based on the various inputs and formula below:
The cut-off grade was elevated to 300 mg/l to increase margin and derisk the uncertainties around price fluctuations. The cut-off grade is used to determine whether the brine pumped will generate a profit after paying for costs across the value chain.
Pumped brine is ultimately collected in a booster station, followed by the evaporation ponds (Chapter 14), where a composite grade is present and can be approximated by a flux-weighted average concentration from the production wells. During the 40-year reserve simulation, extracted lithium grades from individual production wells vary between approximately 815 and 520 mg/l due to dilution over the LOM. The average lithium grade of the Proven and Probable Reserves corresponds to 757 mg/l and represents the flux-weighted composite brine collected before processing. Extracted grades at individual production wells and the average Proven and Probable reserve concentration are well above the 300 mg/l cut-off grade (Figure 12-6), demonstrating that production is economically viable.

SEC Technical Report Summary
12.4 | Uncertainty |
The Brine Reserve estimate may be affected by the following factors:
● | Assumptions regarding aquifer parameters and total dissolved solids used in the groundwater model for areas where empirical data do not exist. |
● | Estimated vertical hydraulic conductivity values which partially control the amount of anticipated future dilution in areas where fresh water overlies brine. |
Regardless of these sources of uncertainty, a steady-state and transient (pumping test) calibration was undertaken using current data followed by a model verification to extracted concentrations to support reserve model predictions. Future calibration efforts will strengthen the model for subsequent predictions.
12.5 | Conclusions |
Based on the modeled hydrogeological system and results of the numerical modeling, it is appropriate to categorize the Proven Brine Reserve as what is feasible to be pumped to the ponds during the first 7 years for each wellfield. The model projects that the wellfields will sustain operable pumping for 40 years; thus, the following 33 years of pumping as a Probable Brine Reserve have been categorized. These values represent about 38% of the total Brine Resource Estimate, Inclusive of Reserves.
The current numerical model projections suggest that additional brine could be pumped from the basin from the proposed wellfields over a period of 40 years. However, recalibration of the model would be required after start-up pumping of each wellfield to refine the model and support this projection.
In addition, exploration should be conducted to better identify and potentially demonstrate additional extractable brine in other parts of the basin. Favorable exploration results represent Project upside potential.
The relative accuracy and confidence in the Brine Reserve estimate is dominantly a function of the accuracy and confidence demonstrated in sampling and analytical methods, development and understanding of the conceptual hydrogeologic system, and construction and calibration of the numerical groundwater model. The input data and analytical results were validated via sample duplication, use of multiple methods to determine brine grades throughout the basin, and with pumping tests. Using these data developed using standard methods, a conceptual geological and hydrogeological model was created consistent with the geological, hydrogeological, and chemical data obtained during the exploration phases.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
In the opinion of the employees of Montgomery & Associates, each phase of the Project was conducted in a logical manner, and results were supportable using standard analytical methodologies. In addition, calibration of the numerical model against long-term pumping tests provides solid support for the conceptual hydrogeologic model developed for the Project. Thus, there is a reasonably high-level confidence in the ability of the aquifer system to yield the quantities and grade of brine estimated as Proven and Probable Mineral Reserves.
To the extent known by the employees of Montgomery & Associates, there are no known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors that could affect the Mineral Reserve estimate which are not discussed in this Report.

SEC Technical Report Summary
13. | Mining Methods |
This section describes the wellfields used for brine extraction and the mobile equipment used to support site operations. The numerical modeling used to support mine designs, simulate production rates, and predict mining dilution is discussed in Chapter 12. Chapter 14 outlines the process operations including the booster ponds, evaporation ponds, and the process plant.
13.1 | Brine Extraction |
Brine operations are not conventional mining operations; the commodity is extracted by pumping from wells rather than excavation from solid rocks or minerals, thus detailed geotechnical studies are not required. There are two stages being considered for production: one in the East (SVWP wells) and the second in the Southwest (W wells), Southeast (S wells), and North (N wells), as shown in Figure 13-1. For Stage 1 (years 1-2), only wells from the East Wellfield (SVWP wells) will be used, while the Stage 2 Expansion (years 3-40) will also utilize the W, S, and N wells. The projected LOM is 40 years and Section 12.3 – Predictive Simulation details the production well schedule and predictive model results.
Figure 13-1 – Current Production Wellfield Map.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The production well locations were selected to reduce long-term freshwater level drawdown and maintain as high a brine grade as possible, given each well location and the potential for brine dilution. During wellfield construction, each production well will be tested and analyzed immediately after construction.
Well depths, well filters, and well casing blind intervals sealed from pumping were designed based on the following factors:
● | Location of lithium-bearing brine zones. |
● | Location of aquifer zones with comparatively large hydraulic conductivity. |
● | Location of existing fresh or brackish water zones, and/or future potential for brackish water to enter the wellfield. |
With the exploration currently undertaken, the average production well depth in the proposed wellfields is approximately 200 m. However, because substantial areas of the wellfields require additional infill characterization, actual depths and completion zones will be determined in the field at each proposed well location. Therefore, modifications to individual well construction plans will be undertaken as necessary during construction drilling based on the actual conditions observed.
Fresh and brackish water zones occur in both proposed wellfield areas. In addition to the upper zones being brackish water in the eastern part of the basin, there are nearby wells to the east of the proposed southwest wellfield where brackish water was also observed in the upper aquifer zones. Therefore, in both wellfields, production wells are designed to seal off the upper part of the aquifer system and in effect, reduce the downward movement of fresh and brackish water into the production zones of wells. Although some subsurface variations exist between the two wellfields, the general design is to seal off approximately the upper 60 m of aquifer at each production well in the Southwest Wellfield and approximately the upper 100 m of aquifer in the eastern wells.
All production wells will be connected through pipelines to centrally positioned booster ponds. The East Wellfield (Stage 1) is designed with 8 operating wells plus one on standby (at peak flowrate seasons). These wells will be equipped with pumps and manifolds to the distribution pipeline. Wells will be cycled on and off as needed to reduce the potential for over-pumping at any given well that could result in excessive drawdown, increased pumping lift, and extra energy costs. Wells on standby will be ready to be turned on when well maintenance or pump repair/replacement is required at other wells.
The annual numerical values and totals for the Life of Mine (LOM) production, including the quantities pumped from the wellfields with associated solution grades, the overall recovery, and final salable product are detailed in the Table 13-1.
Table 13-1 – Annual numerical values and totals of Life of Mine (LOM) production: Sal de Vida Stage 1 and 2
Note: The overall recovery is calculated considering the total lithium units produced relative to the total lithium units pumped out of the wells. It may be affected by the pond inventory and production ramp-up, causing temporary fluctuations. At stable production levels, the overall recovery is approximately 70%.
13.2 | Well Materials, Pads, and Infrastructure |
The materials considered for the brine well area pipelines are HDPE and cross-linked polyethylene (PEX). The maximum capacity of the brine well pumps for this area will be 115 m3/hr each. Each wellfield pump will have a wireless data link to the process plant data acquisition system (SCADA) with remote start/stop capability. Each pump will also have its own dedicated diesel generator and diesel storage tank with three days storage capacity.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Infrastructure in the wellfield will include well pads, access roads and power generation. Each brine well will have its own generator and diesel storage tank, and each tank will have a residence time of 72 hr. A diesel truck will feed the diesel tanks to keep the diesel generators running. All wells will be connected by road to the booster station. Drilling pads will be elevated to as much as 1.5 m above the salar surface to mitigate flooding risks. Drill pad dimensions will have a platform area sufficient to house the required diesel generators and control instrumentation. Figure 13-2 shows a picture of production well SVWP21-02.

13.3 | Equipment |
Mobile equipment will be required for plant operations (Table 13-2). Some transport services will be contracted out to local companies; however, in most cases the equipment will be owned and operated by Allkem. Allkem will provide fuel and servicing for all vehicles, except for offsite reagent delivery and product trucking logistics.

The lithium carbonate product will be packed into 1-m3 bags and loaded onto semi-trailers with side lifters. Trucks will transport the lithium carbonate to the port of Antofagasta in Chile. Lithium carbonate and reagent transport logistics will be outsourced to a local company.
During the first 2 years of operation, Allkem-owned trucks with a 30-tonne load capacity, designed for loose bulk wet solids, will be used to transport the magnesium hydroxide and calcium sulphate that will be precipitated as discards from different areas of the lithium carbonate plant. This material will be transported to the co-disposal area. To move the total amount of solids, several bins will be used to alternate bin loading. Trucks for discard transport will be necessary from Year 2 onward.

Thirty-tonne trucks will be used for maintenance and general freight movement around the site. Mobile cranes with 20-t load capacity will be retained at the site for general maintenance. Forklift trucks will be used at the plant for loading lithium carbonate, handling reagents, maintenance workshop and for the general store. Front-end loaders with backhoe will be required for general site maintenance, such as clearing drains. Water trucks (for dust suppression), graders and rollers will be required for road maintenance on the site and for roads leading into the site.
13.4 | Conclusions |
The described mining method is deemed adequate to support economic brine extraction and is similar in configuration to other lithium brine extraction configurations witnessed on operating properties owned by Allkem.

SEC Technical Report Summary
14. | Processing and Recovery Methods |
The process design is based on the testwork discussed in Chapter 10, and the brine lithium grades and required production schedules defined by the numerical modelling of Li Reserves in Chapter 12. The selected process for Sal de Vida is shown in Figure 14-1. The process plant will operate year-round, with a planned plant availability of 8,000 hours per year. The surge capacity of the buffer ponds will allow the plant throughput to remain constant, while the evaporation rate and pond throughput will vary seasonally.
14.1 | Process Flowsheet and Description |
The process will commence with brine extracted from wells extending to a depth of up to 300 m into the salar. Brine will be pumped to a series of evaporation ponds at a seasonal rate ranging from 53 l/s in winter to 154 l/s in summer, where it will be evaporated to increase the salt concentration beyond the NaCl saturation point. NaCl will precipitate as halite solids that will collect at the bottom of the ponds.
The evaporated brine will be fed into the process plant liming circuit, where it will be combined with a slaked lime (Ca(OH)2) slurry. The lime will react with magnesium, sulphate, and boron ions in the brine, removing these impurities as solid magnesium hydroxide (Mg(OH)2), gypsum, and borate salts. The solids will be separated from the brine and reported to a discard facility.
The limed brine will be fed to the muriate (potassium chloride, KCl) series of evaporation ponds and will be further concentrated, exceeding the saturation point of sylvite (KCl), and causing it to precipitate together with halite (NaCl). Muriate is an archaic term for chloride and muriate of potassium is potassium chloride or sylvite. Usually this occurs as sylvinite which is a mix of sylvite and halite.
A small amount of gypsum (CaSO4●2H2O) will also be precipitated.
The concentrated brine will be sent back to the process plant, where it will be softened to remove the remaining magnesium ions as well as the calcium. The softening circuit will use a combination of both caustic soda (NaOH) and sodium carbonate (Na2CO3) for pH management and divalent ion removal. The solid impurities will once again be separated and discarded.
The clear softened brine will be pumped through a conventional Ca/Mg IX circuit in a lead–lag–regeneration configuration to ensure that trace magnesium and calcium ions still present in the brine are removed. HCl and NaOH or water will be used for stripping and regeneration of the IX resin respectively.
The softened brine will be sent to the lithium carbonate crystallization circuit to crystallize lithium by combining the brine with sodium carbonate at elevated temperatures to produce lithium carbonate. The lithium carbonate solids will be recovered while the liquor will be recycled back into the process.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Finally, the lithium carbonate solids will be processed through a product finishing circuit for drying, cooling, micronizing, and bagging.
The process was simulated using an in-house pond evaporation model developed by Galaxy, together with a METSIM simulation of the process plant.
14.1.1 | Halite Evaporation Ponds |
The objective of the halite evaporation ponds is to evaporate the brine to reduce the volume that must be processed through the liming plant, while also increasing the lithium concentration. In the process, sodium and chloride impurities will reach saturation and will be precipitated as halite salts. The brine will be evaporated until the lithium concentration reaches 0.7% by weight.
The key parameters used in the pond model are the concentration of magnesium at the inlet and outlet of each pond, and the outlet brine required. For the first pond in the sequence, the inlet concentration was known from analysis of the raw brine from the wellfields. For the final pond in the sequence, the required magnesium concentration is the value in the concentration path data corresponding to a concentration of 0.7% Li. For all other ponds, the inlet and outlet magnesium concentrations were determined iteratively, such that sequential ponds would decrease in area as their average brine concentration increased. This approach was taken to minimize the impact of leakage on lithium recovery (leakage is proportional to area, so it was preferred to minimize the area of ponds with a higher lithium concentration).
The ions included in the pond brines will be Mg2+, Ca2+, Na+, K+, Li+, Cl-, SO42- and B (present as a variety of borates). In the halite ponds the sodium saturation value is based on the concentration path correlations (see Section 10.2.9).
14.1.2 | Liming |
The objective of liming is to remove magnesium from the brine. Brine will be treated with milk-of-lime, a hydrated (slaked) lime slurry as Ca(OH)2, to precipitate magnesium as Mg(OH)2. Other solids produced will include borate solids and gypsum (CaSO4●2H2O). The slurry of limed brine and precipitated impurities will be sent to a thickener for solid–liquid separation. The underflow will be combined with the solids from the softening circuit and filtered in the primary liming filter. The filtrate will be recombined with the thickener overflow—this clear liquor will be the limed brine that is pumped to the muriate ponds for further evaporation.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Figure 14-1 – Sal de Vida Simplified Process Flow Diagram.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
14.1.3 | Muriate Evaporation Ponds |
After liming, the clarified limed brine will be pumped to the muriate ponds for further evaporation to bring the lithium concentration up to 1.7% by weight. The principles behind the muriate ponds are very similar to those of the halite ponds, and they were modelled with the same evaporation pond model. The key difference with the muriate ponds is that the brine will be evaporated beyond the saturation point of KCl, such that significant amount of sylvite salts will be precipitated along with the halite. Some calcium will also be precipitated as gypsum. A set of evaporation curves were developed by evaporating limed brine from the pilot plant on site (see Chapter 10.2.9).
14.1.4 | Softening |
Once the target lithium concentration of 1.7% is achieved in the muriate ponds, the brine must be softened to remove calcium and magnesium impurities. The brine will be heated using a two-step process at mild temperatures (~20°C) and sent to a series of six softening and mixing tanks to allow the brine to react with all reagents. The addition of 25% soda ash (sodium carbonate) solution in the softening circuit will enable the precipitation of magnesium hydroxide and calcium carbonate, as solids within the brine and pH adjustment.
Filtration will be used to remove the calcium and magnesium precipitates from the brine. This will be achieved by using a plate and frame filter to remove the bulk of the solids. It will be followed by a secondary filtration stage for final polishing. The result will be a clarified softened brine with near-negligible calcium and magnesium concentration. The clarified softened brine will be conditioned before it is fed into a Ca/Mg IX circuit. The Ca/Mg IX circuit will be a standard circuit, consisting of three columns, in a lead–lag–regeneration, merry-go-round configuration. Small amounts of HCl and NaOH or RO water will be used for stripping and resin regeneration. The treated softened brine will then be stored in two softening filtrate tanks to be used as feedstock for crystallization.
The filter cake will be pumped to the liming circuit where it will be combined with the liming thickener underflow prior to filtration. The combined reject filter cake reports to the discard facility.
14.1.5 | Lithium Carbonate Crystallization |
Lithium carbonate will be recovered from the purified brine by a crystallization reaction with sodium carbonate at elevated temperatures of about 84°C:
2LiCl(aq) + Na2CO3(s) → Li2CO3(s) + 2NaCl(aq)
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Sodium carbonate will be added as a solution at a concentration of 25%. The reaction will be performed in a series of heated mixing tanks (crystallizers) operated at 84°C. Higher temperatures increase the crystallization efficiency because lithium carbonate solubility decreases with increasing temperature. The temperature will be limited by the low air pressure, given the altitude at Sal de Vida, which will reduce the solution boiling point. Ideally, the circuit will be run at just below the boiling point. A seed recycle stream of lithium carbonate crystals will be implemented to improve crystal growth by providing the precipitating lithium carbonate with a surface on which to grow.
After crystallization, the lithium carbonate solids will be recovered from the mother liquor by a hydro cyclone and a centrifuge. The solid cake will be subjected to a displacement wash on the centrifuge, before being conveyed to product finishing for drying and micronizing.
The mother liquor will be combined with the softening and liming solids, before being recovered via the liming filter (essentially acting to wash the solid waste to recover entrained lithium) and sent to the halite ponds as a recycle stream.
14.1.6 | Product Finishing |
The purpose of the product finishing circuit is to perform the final physical operations required to make the lithium carbonate suitable for transport to customers.
First, the lithium carbonate solids will be dried to <1% moisture, before being filtered and cooled. The solids will be micronized, and iron contaminants will be removed magnetically. The micronized product will then be bagged for transport.
14.2 | Process Facilities |
The process facilities have been divided in the following main areas:
● | Wellfield and brine distribution. |
● | Solar evaporation ponds. |
● | Production plant (liming and lithium carbonate plant). |
● | Waste disposal. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
As seen in Figure 14-2, the East Wellfield for Stage 1 will be located directly above the east sub-basin of the Salar del Hombre Muerto over the salt pan. Stage 1´s ponds will be located in two areas directly south and Stage 2´s ponds will be located southeast of the Southwest Wellfield. The brine distribution system will traverse the salar toward where the evaporation ponds will be located. The location of the ponds has been determined based on a number of a factors including optimal constructability properties and minimizing earthworks, environmental impact, and risk of flooding.
The processing plant for all stages will be sited in the center of Stage 1’s evaporation ponds. A road system, including ramps and causeways, will connect the processing facilities and provide access to all working areas. The waste disposal areas will surround the evaporation ponds to the north, east and southeast.

SEC Technical Report Summary
14.2.1 Wellfield and Brine Distribution
14.2.1.1 Wells
The first step in the lithium recovery process is the extraction of brine from the hydrogeological reserve via well pumps. The wellfields and associated infrastructure are described in Chapter 13.
14.2.1.2 Booster Station
A booster station will mix brine from the different wells, both acting as a buffer for the seasonal flow changes and as a brine pumping station to reach the halite ponds. The station will consist of two booster station ponds, which will operate in parallel based on volume requirements. During summer, both ponds will operate; during winter, only one pond would be used. These ponds will be regularly cleaned; the cleaning frequency will depend on the amount of salt that may precipitate out on the pond bottom.
Five transfer pumps will be located at the pond outlets, operating with four pumps on duty and one on standby. Pumps will have a wireless data link to the process plant SCADA system with remote start/stop capability.
Stage 1 design includes one booster station in the East Wellfields. Stage 2 will require two booster stations in the Southwest Wellfield.
14.2.1.3 Brine Distribution
The brine distribution system will connect all wells with the booster station. From there, brine will be pumped to the evaporation ponds. The piping system requires separate lines from each pump station to the booster ponds. From the booster ponds three booster pumps will feed a single pipeline, which will deliver brine to the evaporation ponds. The design includes trenches for laying pipelines and suitable ground-anchoring systems. Pipeline design includes section divisions at 100-m spacing for pipeline flushing/cleaning. The pipeline materials for this area will consist of HDPE and PEX. Instrumentation will be implemented accordingly for these areas.
Brine well instrumentation will include instrumentation for the operational safety of the pumps (pressure and temperature) as well as instrumentation to monitor process variables (e.g., liquid level in each well and brine flow from each pump). In the booster station area, instrumentation will be required for the booster station ponds and the outlet pumps. The booster station ponds will monitor the brine levels through the use of radar sensors, and sending the data collected to the control system. The booster station pumps will have instrumentation for pump operational safety (e.g., measuring pressure and temperature) as well as instruments that will measure process variables (e.g., total brine flow to the pumps).

14.2.2 Solar Evaporation Ponds
The solar evaporation pond system will consist of a series of halite and muriate evaporation ponds, which will concentrate brine suitable for feeding a lithium carbonate plant. The evaporation ponds for Stage 1 will be located in two areas on the northeastern corner and southeastern edge of the Río de los Patos alluvial fan, over a large gravel field directly south of the East Wellfield and above the salar, covering a total area of approximately 450 ha. The halite evaporation ponds for Stage 2 will be located on the northwestern corner of the Río de los Patos alluvial fan, over a large gravel field directly southeast of the Southwest wellfield covering an area of approximately 850 ha. The muriate evaporation ponds for Stage 2 will be located next to the Stage 1 halite ponds and will cover approximately 50 ha.
14.2.2.1 Halite Ponds
Halite ponds for Stage 1 will be arranged in three strings which will operate in parallel. Strings 1 and 2 will be located immediately north of the process plant in the northeastern corner of the alluvial fan and String 3 will be located about 1.5 km southeast of the process plant. Each string will contain six cells plus a buffer pond with the flow from one pond to the next in series. The halite system will have a total surface area of approximately 400 ha, divided evenly among the three strings. The key assumptions that were used in the halite pond design were:
● | Average evaporation rate of 2,700 mm/a. |
● | Evaporation derating factor of 0.7 for pond size. |
● | Evaporation derating for brine activity based on empirical correlations with Mg and Li. |
● | Availability derating based on estimated harvesting times (approximately 91% on average). |
● | Average leakage rate of 0.03 mm/d. |
● | Lined ponds. |
● | Depth of 1.2 m including 0.3 m freeboard. |
● | Entrainment loss factor of 0.14 tonnes of brine per tonne of precipitated salt (conservative based on pilot pond harvesting detailed in Section 10.2.9). |
A 0.3 m permanent salt bed layer will be maintained on the pond base to protect the liner during harvesting. That layer would not be harvested. A maximum 0.3 m high harvesting layer will be formed on top of the salt bed layer and the liquid pond depth will be controlled to stay around 0.3 m above the harvest salt layer.
Pond construction will consist primarily of cut-and-fill earthworks and, if required, local quarry material would be introduced. The ponds will be lined with a geomembrane that would consist of a HDPE layer installed above the soil to waterproof the ponds.

SEC Technical Report Summary
14.2.2.2 Muriate Ponds
The muriate ponds will be located south of the Stage 1 halite ponds strings 1 and 2, adjacent to the process plant. The muriate pond system will consist of a muriate buffer pond, two strings of muriate ponds operating in parallel with three cells each, and two concentrated brine storage ponds. Brine will flow from one pond to the next in series. The system will also include a mother liquor buffer pond located between the process plant and Strings 1 and 2 of the halite ponds. The muriate system will have a surface area of approximately 26 ha for Stage 1 and 52 ha for Stage 2.
The key assumptions used in the muriate pond design include:
● | Average evaporation rate of 2,700 mm/a. |
● | Evaporation derating factor of 0.7 for pond size. |
● | Evaporation derating for brine activity based on empirical correlations with Mg and Li. |
● | Availability derating based on estimated harvesting times (approximately 91% on average). |
● | Average leakage rate of 0.02 mm/d. |
● | Lined ponds. |
● | Depth of 1.2 m including 0.3 m freeboard. |
● | Entrainment loss factor of 0.11 tonnes of brine per tonne of precipitated salt (conservative based on pilot pond harvesting detailed in Section 10.2.9). |
A 0.3 m permanent salt bed layer will be maintained on the pond base to protect the liner during harvesting. That layer would not be harvested. A maximum 0.3 m high harvesting layer will be formed on top of the salt bed layer and the liquid pond depth would be controlled to stay around 0.3 m above the harvest salt layer.
Pond construction will consist primarily of cut-and-fill earthworks and, if required, local quarry material would be introduced. The ponds will be lined with a geomembrane that would consist of a HDPE layer installed above the soil to waterproof the ponds.
14.2.2.3 Pond Infrastructure
Weirs will be used to transfer brine between the same pond types. Weirs will have a width of 5 m to allow for the correct flow between the ponds. The connection between ponds through weirs will allow for a constant natural flow from one pond to the next and will keep the same brine level in all ponds, reducing pump usage. Since the brine transferred between ponds is saturated, the weirs will have to be periodically cleaned to reduce salt accumulation. For brine transfers over longer distances (i.e., between halite and muriate ponds) pumping will be required. The pump type and size will depend on application. The expected maximum flow is 450 m3/hr. All pumps and pipelines will have a connection point to periodically flush any salt scaling build-up. The washing frequency will be determined during operations.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The feed to the pond system is provided by the booster pumps from the booster station area. Pumps in the pond area will consist of mobile transfer pumps, fixed transfer pumps from the Mother Liquor and Muriate Buffer Ponds, and the feed pumps to the liming and process plants.
The road system will connect all of the processing facilities and provide access to the working areas. Roads, ramps, and causeways will be designed based on the vehicle types that will be used. In the evaporation ponds area, roads will be designed to externally circumnavigate the berms. These roads will be designed with a width that is sufficient to allow the transit of harvest trucks, which will be operating during salt harvest from each pond. A ramp will be constructed during pond harvest using harvested salts from previously harvested ponds to allow the truck access into each pond. Internal roads for light vehicles, buses, and heavy vehicles supplying reagent or diesel, will be constructed for production plant support.
14.2.2.4 Operational Monitoring and Control
The first process step will consist of pumping brine into the halite ponds to initiate lithium concentration through evaporation. Evaporation will result from the combination mostly of solar radiation, wind, temperature, and relative humidity. The evaporation area required was calculated based on the expected evaporation rates and the well flow rates.
Chloride salts (primarily sodium chloride) will precipitate and deposit in the pond bottom. To avoid increasing the bottom salt level inside each pond above an optimal operational level, these salts will be periodically harvested, and stockpiled in accordance with environmental requirements.
The muriate ponds will be physically located adjacent to the halite ponds and will consist of two strings. Brine will be transferred from the muriate buffer pond to each muriate pond string. The muriate ponds have the same design basis as the halite ponds (depth, liner, layer depth) and will also be harvestable. When the brine reaches an overall concentration of ~21 g/l, it will be stored in a set of concentrated brine storage ponds, from where the brine would be fed to the lithium carbonate plant.
The concentrated brine storage ponds will act as buffer ponds to accommodate seasonal flow variations.
All evaporation ponds will be harvestable, with a harvesting frequency of approximately once a year. The estimated annual total of salt harvest from the halite ponds is 1.4 million tonnes per annum (tpa), and from the muriate ponds is 79,000 tpa for Stage 1 of the Project. For Stage 2, the annual halite harvest will be 2.8 million tpa, and a muriate harvest of 158,000 tpa.
There is an initial hold-up of 0.21 tonnes of pond brine in each tonne of salt. During harvesting, the salt is drained and compacted to collect the brine in channels and sumps, from which it can then be recovered using mobile pumps. Based on the pilot pond harvesting test (Section 10.2.9), this allows a harvesting recovery of 0.12 tonnes of brine per tonne of harvested salt.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The harvested salt will be stockpiled in areas lined with 1 mm HDPE. Brine will be drained from these stockpiles and collected in sumps for pumping back to the ponds to improve the overall pond recovery.
The total brine level in each pond, the total salt level in each pond and the chemical composition will require control. The total brine level of the ponds and the salt level will be measured manually or through topography. The chemical composition will be measured through laboratory analysis of a manually taken brine sample. The inlet flow will be measured in four places:
● | At the inlet to the first halite pond of each string. |
● | At the inlet to the first muriate pond of each muriate string. |
Flow rates will be monitored using flowmeters and tracked in the control room via a control system. Flow rates will depend on seasonal fluctuations.
14.2.3 Process Plant
The process facilities will consist of a lithium carbonate plant, with a liming plant and associated plant infrastructure, such as the power station, fueling and workshops. The process facilities will be located in an area adjacent to the muriate ponds south of the Stage 1 halite ponds.
14.2.3.1 Liming Plant
The liming plant will include the following equipment:
● | Liming mixing tanks. |
● | Heat exchangers. |

● | Sump pumps. |
The pump types to be used will depend on the specific application, and pump sizes would vary between 20 – 100 m3/hr. Pipeline material will also depend on the specific application.
14.2.3.2 Softening Stage
The softening stage will include the following equipment:
● | Softening mixing tanks. |
● | Heat exchangers. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Storage tanks. |
● | Storage hoppers. |

● | Ion exchange columns. |
● | Pumps. |
● | Sump pumps. |
The pump type to be used will depend on the specific application in this area, and pump size will vary from 4 – 67 m3/hr. Pipeline material will also depend on the specific application.
14.2.3.3 Crystallization Stage
The crystallization stage will consist of the following:
● | Crystallization mixing tanks. |
● | Heat exchangers. |
● | Storage tanks. |
● | Storage hoppers. |
● | Cyclones. |
● | Centrifuges. |
● | Cartridge filters. |
● | Pumps. |
● | Sump pumps. |
The pump type will depend on the specific application in this area, and pump sizes will vary from 7 – 69 m3/hr. Pipeline material will also depend on the specific application.
14.2.3.4 Product Finishing
The main equipment requirements in the product finishing plant include:
● | Belt conveyors. |
● | Hoppers. |
● | Screw feeders. |
● | Drying system (includes air heater, dust collector and air heat exchanger). |

SEC Technical Report Summary
● | Magnets. |
● | Vibrating screen. |
● | Bagging system (includes storage hopper, samplers, vibrator, and conveyor for final product big bags). |
● | Product storage shed. |
14.2.3.5 Reagents Area
Each reagent will have its own preparation area, with equipment consisting of feed hoppers, mixing tanks and storage tanks. Reagents will be transported to the plant site in a solid state and be prepared based on the process requirements.
14.2.3.6 Process plant operations and controls
When the brine reaches a suitable lithium concentration in the halite ponds (8.9 g/l, 0.7 wt%), it will be stored in three liming plant buffer ponds, designed to store brine, and handle all seasonal variations in the brine flow. From these buffer ponds, brine will be fed to the liming stage, which is the first purification process that requires the addition of reagents. A solution of milk-of-lime (Ca(OH)2) will be added to the brine inside agitated mixing tanks that will operate in series, increasing pH and precipitating magnesium as magnesium hydroxide, as well as removing other unwanted elements from the brine, such as boron and sulphates. The limed brine will be pumped to solid – liquid separation equipment (thickeners and press filters), to separate the precipitated solids from the lithium- concentrated brine. The solids will be sent to a final disposal area. The lithium-concentrated brine will be pumped to a muriate buffer pond and distributed to the muriate ponds. It will evaporate to ~21 g/l Li and will be stored in the concentrated brine storage ponds, which will handle all seasonal variations in the brine flow similarly to the liming buffer ponds.
The lithium carbonate plant was designed to produce 15,000 tpa of lithium carbonate in Stage 1, with Stage 2 enabling the production of an additional 30,000 tpa. This design was based on average brine supplies of 26 m3/hr and 52 m3/hr for Stage 1 and 2 respectively, and an average lithium concentration of 21 g/l in the softening feed. The plant will operate continuously with a design availability of 91%.
Brine coming from the concentrated brine storage ponds will enter a softening stage, where magnesium and calcium will be removed from the brine. The brine will enter the plant at a temperature of around 0°C and will be stored in an evaporated brine storage tank where it will be diluted slightly with RO water. It will be heated to 20°C by a spiral heat exchanger and a plate heat exchanged in series, which will use recirculation of process streams and hot water respectively as heating agents. The heated brine will enter a group of six softening mixing tanks, which will operate in series, to allow the correct residence time for the brine to react with all reagents. Caustic soda will be added in the first mixing tank, and pH will be controlled in the third tank. The brine will be mixed with a sodium carbonate solution in the fourth softening mixing tanks. Both reagents will react with the divalent ions left in the brine and precipitate magnesium hydroxide and calcium carbonate (CaCO3), as solids within the brine. The brine and precipitated solids will be subject to a solid–liquid separation stage, to remove all solid contaminants, using press filters and polish filters. The lithium-concentrated brine will be sent to storage tanks to feed the ion exchange columns. Solid contaminants will be sent to a filter cake tank to be re-pulped with the liming area waste/discards and then sent to the discard facility.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The softened brine will be passed through ion exchange columns to remove any residual calcium and magnesium in solution. It will then be stored in two softening filtrate tanks to be used as feedstock for crystallization.
Lithium-concentrated brine from the softening stage will feed the crystallization stage at a rate of 28 m3/h for Stage 1 and 56 m³/h for Stage 2 and will have a lithium concentration of around 14 g/l and will be contaminant-free. The first crystallization step will consist of feeding the brine through a spiral heat exchanger and a plate heat exchanger operating in series, increasing the temperature of the brine from 21°C to 85°C. Hot mother liquor recycle will be used as a heating agent in the first heat exchanger. Saturated steam will be used in the second heat exchanger and will be obtained from a boiler. The heated brine will feed a group of five crystallization mixing tanks that will operate in series. Sodium carbonate, with a concentration of 25% w/w, will be fed to the first and second crystallization mixing tanks, where the reagent will react with the dissolved lithium contained in the brine and precipitate lithium carbonate as a solid inside the tanks. To separate the precipitated lithium carbonate with the brine solution, the crystallization mixing tank outlets will feed a crystallization cyclone cluster for dewatering. 50% of the cyclone cluster underflow, which is the precipitated lithium carbonate, will be returned to the crystallization mixing tanks as a seed recycle. The other 50% cyclone cluster underflow will be sent to the centrifuge stage for lithium carbonate recovery and washing. The centrifuge stage will consist of three centrifuges operating in duty/duty/standby configuration. The centrifuge stage process will operate in batch mode. Each centrifuge will have specific loading, centrifuging, washing, and unloading stages. The final washed, low-moisture content product will be fed to the product finishing stage. All equipment in the crystallization stage will be thermally insulated.
14.2.3.7 Product Finishing
Following dewatering and washing in the centrifuge the wet lithium carbonate solids will be transported via a belt conveyor to a surge hopper and then via a steep incline belt conveyor to the dryer to reduce the moisture content to less than 1 wt%. The dryer is fed via a surge hopper to allow continuous operation, because the centrifuges discharge wet product for 5.5 minutes in a 22-minute cycle. A diverter gate before the surge hopper enables the bagging of wet product. Filtered ambient air will be preheated to 101 °C by the 149 °C exhaust air from the dryer and to 400 °C by an electric air heater before entering the dryer to remove moisture from the product solids. The solids entrained by the dryer exhaust air will be removed by the dust collector upstream of the air preheater. The cleaned air will be discharged to atmosphere, while the hot lithium carbonate solids at 149 °C will be discharged from the bottom of the dryer and dust collector via rotary valves and pneumatically transported to the bulk solids heat exchanger cooler to cool to 50 °C prior to transferring by pneumatic conveyance to the lithium carbonate hopper. The cooler will use RO water, which will then be directed to the hot RO water tank.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Product from the hopper will be fed via a rotary valve to the micronizer through a grate magnet to remove ferrous (magnetic) contaminants. A portion of the filtered ambient air drawn from the downstream fan will entrain via a feed chute the product solids fed by a rotary valve to the air classifier mill. The remaining filtered ambient air will be combined with the solids transport air in the air classifier mill. The solids size will be reduced from 100% < 4 mm with a d50 of 55 – 57 µm to 100% < 40 µm with a d50 of 5 – 6 µm. The milled product solids will be collected by the air classifier mill bag filter and the clean air will be discharged to atmosphere via the mill fan. Lithium carbonate product in the lithium carbonate hopper, which will not be micronized will be pneumatically transported via a rotary valve to contaminants removal.
The product solids will be removed from the bottom of the air classifier mill bag filter by a screw feeder and then fed by a rotary valve to a circular vibrating screen to remove non-magnetic contaminants before conveyed to the downstream equipment. The removal of ferrous (magnetic) contaminants to a specification of <400 ppb is achieved, first by the RO water cooled dry vibrating magnetic filter and then by a grate magnet. Similarly, non-ferrous, and ferrous contaminants in the non-micronized lithium carbonate product will be removed by a dedicated circular vibrating screen, dry vibrating magnetic filter and grate magnet.
The micronized BG lithium carbonate product will then be pneumatically transported to the product storage bin and then via a rotary valve packed into 1 ton (2-m3) bulk bags and stored for export. The non-micronized lithium carbonate product will similarly be pneumatically transported to the non-micronized product storage bin and via a rotary valve packed into 1 ton (2-m3) bulk bags and stored for export.
The bagging system will fill labelled maxi bags (or big bags) with solid lithium carbonate. Automatic sampling will be carried out in the storage bin inlet of the and manual sampling will be conducted on each filled maxi bag. All samples will be sent for laboratory analysis. The filled and sampled maxi bags will be stored in a product storage shed, prior to dispatch. The storage shed will have a one-month storage capacity.
14.2.4 Waste Disposal
This facility will consist of halite, muriate, and co-disposal stockpiles surrounding the halite ponds and will cover a total area of approximately 300 ha for Stage 1 and 600 ha for Stage 2. All waste/discards from the process will be appropriately treated, stockpiled, and stored to comply with corporate and environmental requirements.
The main process waste/discards will include:
● | Solid discards from the evaporation ponds: these would consist of harvested salts from the halite and muriate ponds. These salts would be generated from year two of production, since the salt layer and harvestable layer must be in place at the base of each pond before the first |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
harvest can be undertaken. The estimated annual total of salt harvested and stockpile from the halite ponds is 1.4 million t/a, and from the muriate ponds is 79,000 tpa for Stage 1 of the Project. For Stage 2, the annual salt harvest will be 2.8 million tpa and 158,000 tpa for halite and muriate ponds respectively. |
● | Solid-liquid waste/discards from the process plant: |
○ | Liming solid discards: primarily precipitated magnesium hydroxide, borate salts and gypsum. Around 80,000 dry tpa are estimated to be produced in Stage 1 and 160,000 in Stage 2. |
○ | Softening solid discards: primarily precipitated calcium carbonate and magnesium hydroxide. Around 12,800 and 25,300 dry tpa are assumed to be produced in Stage 1 and 2 respectively, which are combined with the liming solids and transported by truck to co-disposal stockpiles. |
○ | Mother liquor that is not used in the process: while most is recycled, a portion of the mother liquor generated from the lithium carbonate plant is entrained as moisture in the liming filter cake and will be disposed of on the co-disposal stockpiles along with the solids. This acts as a natural ‘bleed’ stream, preventing the build-up of contaminants from the recycle stream. |
○ | RO plant retentate. |
○ | Steam boiler retentate. |
● | Any sump pump solutions that cannot be recycled within the process. |
The majority of the mother liquor from the crystallization stage will be recycled into the process (see Section 14.1.5) and will therefore not require a dedicated disposal method or facility.
14.2.4.1 Solids Disposal (Harvested Salt and Co-Disposal Stockpiles)
The co-disposal area, approximately 300 ha in area for Stage 1 and 600 ha for Stage 2, will be used for the storage of both discards/waste from the process plant as well as harvested halite salts. Since the generation of solid-liquid discards from the process plant begin before the harvest of any salts from the pond, these discards will be treated differently during the first two years. During this period, all liquid discards generated from the process plant would be sent to an event pond (see Section 14.2.4.1), which will be located near the plant. After year two of production, the event pond will only be used for unprogrammed events such as flooding or plant spills. All process plant solid discards from that point onward will be sent to the co-disposal area for stockpiling.
From year two of production onward, the solid salts harvested from the halite evaporation ponds will be sent to the same co-disposal area and will be deposited around the initial two years of solid stockpile that will have built, generating a containment dam. From year two of production onward, both liquid and solid wastes from the process plant (including the small portion of mother liquor entrained in the solid cake) will be mixed in a tank located near the production plant and will be sent as a pulp (or slurry stream) to the co-disposal area, to be co-disposed in the containment dam within the halite salts. This setup will operate for the remainder of the Project life.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Not all harvested halite salts will be sent to the co-disposal area. Some halite salts will be stockpiled separately to be used as construction material for future evaporation ponds. These salts will be sent by truck directly to the halite stockpile area. The total area required for the halite stockpile is 93 ha.
All muriate salts that are harvested will be separately stockpiled. These salts will be sent by truck directly to the muriate stockpile area, after being harvested. The total area required for the muriate stockpile is 10.7 ha for Stage 1 and a further 21 ha for Stage 2.
The infrastructure in the stockpile and co-disposal areas will consist of:
● | Access roads to each stockpile and co-disposal area, accessible by trucks and light vehicles. |
● | HDPE liner (1 mm) to waterproof the area and allow drainage from the harvested salts and plant solids to be collected and returned to the ponds, improving the overall process recovery. |
● | Containment system such as low-height berms, for any liquids that may permeate from the salt stockpiles. |
No other major infrastructure is required for this area.
14.2.4.2 Liquids Disposal (Event Pond)
A lined disposal pond will be located adjacent to the process plant and will be used to evaporate the liquid aqueous waste from the process plant. RO retentate, demineralization retentate and any unprogrammed ‘events’ (such as spillages and flooding) will be sent to this pond for evaporation.
14.3 Process Control Strategy
Process control will be achieved using the supervisory control and data acquisition (SCADA) system, which will consist of computers, networked data communications, and a graphical user interface for process supervisory management at a high level. The SCADA system will interact with PLCs to continuously monitor the input values from sensors and the output values for actuator operations. Operators will interface with the SCADA system using a PC-based operator interface terminal (OIT) from the process plant control room.

14.4 Consumables and Reagents
14.4.1 Water
Raw water will be pumped from Well SVWF 12_19 to the raw water storage tanks. From these tanks, the raw water is distributed around the plant including lime slaking, product cooling and RO water production. RO water will be produced from raw water by an onsite RO plant and will be used for sodium carbonate and caustic preparation, as hot water for process heating and as feed for the demineralization plant. The demineralization water will be used as boiler feed water. Other than the raw water stream, the only water input to the process will be the raw brine. Water will exit the process through pond evaporation, entrainment in harvested salt deposits, pond leakage, process discard streams (which include RO and demineralization retentate as well as filter cake discards), general water losses from evaporation throughout the process plant, and as entrained moisture in the lithium carbonate product.
14.4.2 Steam
Steam will be used for sodium carbonate storage and crystallization heating, mixing, and thickening. Steam will also be used to heat RO water. The steam boiler will be housed in a dedicated building with fire-resistant walls. The boiler for Stage 1 will produce 6.6 t/hr of saturated steam ~5 bar g.
A diesel bulk tank and the deaerator tank will be located outside the building.
14.4.3 Compressed Air
The process plant will require compressed air for the main equipment and instrumentation. For all users the quality will be 1-2-1, based on ISO 85731 specifications. The supply will include dry air vessel, three screw compressors, filters, and an adsorption dryer unit.
14.4.4 Reagents
Lime will be delivered as quicklime in solid granule form and will be slaked with raw water to produce hydrated lime slurry for the liming circuit.
Sodium carbonate (soda ash) will be delivered in solid powder form and dissolved in RO water to produce sodium carbonate solution for the softening and lithium carbonate crystallization circuits.
Caustic soda will be delivered as a solid and dissolved in RO water to produce a 50% caustic soda solution.

14.7 Conclusions
It is the opinion of the employee of Gunn Metallurgy that the test work conducted is in concept appropriate and well-conceived and the described process design is reasonable and implementable. The process concept is largely standard and has been previously proven to produce similar products. The process design is based on the conducted test work and should reflect the related test work parameters. The process related equipment is suitably organized to produce the mentioned products in the quantities specified, however the employee of Gunn Metallurgy has no basis to comment on the sizing of and so the capacity of the selected equipment. The reagent and commodity consumption rates are deemed appropriate for the process selected and the targeted plant production rate.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The employee of Gunn Metallurgy has reviewed the testwork, mass balance and design criteria, however this does not constitute an independent review of the test work and its interpretation into plant design. The employee of Gunn Metallurgy is not able to rigorously assess whether the plant design as described is adequate for the specified duty, however based on previous experience the plant design does appear to be capable of producing lithium carbonate at the specified cost and of the claimed quality.
The employee of Gunn Metallurgy cannot attest to the reliability of the overall plant recoveries as presented in section 10 for several reasons:
1. | The basis for the selection of pond areas is not adequately defined and so the nominated lithium concentrations may not be achieved, which consequently could impact production rates. |
2. | The assumption by Allkem that in the short term the mother liquor lithium content can be ignored for the purpose of calculating overall recovery of lithium. |
3. | The conceptual vulnerability of the plant operation and so production to disruptions in the softening area. |
14.8 Recommendations
The design of the Stage 1 ponds and plant should be reviewed by an independent party. Upon the completion and operation of Stage 1, operational trends and plant performance must be considered for the Stage 2 plant designs toward optimizing and enhancing production.

15.1 | Road and logistics |
Site roads will range from 6 – 11 m wide depending on the traffic requirements. The road elevation will be sufficient to maintain the roads as operable throughout normal weather conditions. The road surface will be treated with local material from borrow pits. Maintenance will be performed periodically, and salt will be used, once available, to strengthen and provide longevity to the roads.
Since the salar is prone to flooding during the rainy season, suitable road embankments will be constructed to allow permanent access. Causeways connecting the East wellfield will consist of 3.6 m wide single lane roads with stopping bays constructed at an elevation 0.5 m. During operations, salt harvesting material will be used to further elevate the causeways up to 1.5 m above the surface of the salar and allow sufficient height for insertion of drainage pipes where required.
The main access road connecting the site with the national road network traverses the Río de los Patos and the Río Aguas Calientes. Two river crossings are required to enable inbound/outbound logistics.

SEC Technical Report Summary
15.12 | Steam System and Water Heating |
The boiler system will consist of two boilers each capable of supplying 50% of the total heating requirements of the plant, which includes the heating provided by the hot RO water and mother liquor. Each boiler will be an OEM supplied package which will include a de-aerator, burner, boiler, flu gas stack and steam distribution system. Inlet streams include water from the demin circuit and condensate return. Diesel is pumped from the diesel storage tanks into the boilers.
Outlet streams from the boilers include steam to the crystallization circuit, and steam to sodium carbonate mixing. Steam will heat cold RO water to produce hot RO water when not possible to recover heat from the diesel generators. Steam requirements in the process plant facilities will be equivalent to the 13 t/hr.
15.13 | Compressed Air System |
Compressed air services for the process plant will be a vendor supplied package. Two plant air compressors, with a third on standby, will distribute compressed air through a filter following by two air dryers in parallel and another filter to a receiver. From there the air will be distributed to service instrument and plant air. Instrument air will be dry and clean air and will be used for pneumatic instrumentation. In addition, another air compressor and drying/filtration system will provide air to the vehicle workshop.
15.14 | Construction Materials |
Project construction materials can be roughly separated into two different areas, the wellfield and ponds, and the industrial process area.
The brine wells comprise mainly the well casing, its pump, manifold, and its electrical equipment. Then the brine pipelines are made of plastic materials (e.g. HDPE), and the ponds are run from an earthwork platform with its embankment, and then lined (LLDPE, HDPE).
Regarding the industrial area, bulk materials are:
● | concrete foundations and pavement. |
● | steel structures and supports. |
● | steel and plastic piping, cables trays and wiring, etc. |
Regarding process equipment:(thickeners, conveyors, cyclones, boilers, compressors, pumps, filters, steel and plastic tanks, agitators, centrifuges, bagging equipment, heat exchangers, etc.) the main characteristic for process piping and equipment is that they need to deal with salt incrustation, acid, hydroxide, etc., so in many cases plastic material and some exotic steels are used. Most of these materials require certain engineering progress to be specified, and at the same time they are not produced in Argentina. Therefore, purchasing these materials is an important issue to consider.

16. | MARKET STUDIES AND CONTRACTS |
The information on the lithium market is provided by Wood McKenzie, a prominent global market research group to the chemical and mining industries. Wood Mackenzie, also known as WoodMac, is a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries.
Supplementary comments are provided by the Allkem internal marketing team based on experience with Olaroz Project product marketing.
16.1 | Overview of the Lithium Industry |
Lithium is the lightest and least dense solid element in the periodic table with a standard atomic weight of 6.94. In its metallic form, lithium is a soft silvery-grey metal, with good heat and electric conductivity. Although being the least reactive of the alkali metals, lithium reacts readily with air, burning with a white flame at temperatures above 200°C and at room temperature forming a red-purple coating of lithium nitride. In water, metallic lithium reacts to form lithium hydroxide and hydrogen. As a result of its reactive properties, lithium does not occur naturally in its pure elemental metallic form, instead occurring within minerals and salts.
The crustal abundance of lithium is calculated to be 0.002% (20 ppm), making it the 32nd most abundant crustal element. Typical values of lithium in the main rock types are 1 – 35 ppm in igneous rocks, 8 ppm in carbonate rocks and 70 ppm in shales and clays. The concentration of lithium in seawater is significantly less than the crustal abundance, ranging between 0.14 ppm and 0.25 ppm.
16.1.1 | Sources of Lithium |
There are five naturally occurring sources of lithium, of which the most developed are lithium pegmatites and continental lithium brines. Other sources of lithium include oilfield brines, geothermal brines, and clays.
16.1.1.1 | Lithium Minerals |
● | Spodumene [LiAlSi2O6] is the most commonly mined mineral for lithium, with historical and active deposits exploited in China, Australia, Brazil, the USA, and Russia. The high lithium content of spodumene (8% Li2O) and well-defined extraction process, along with the fact that spodumene typically occurs in larger pegmatite deposits, makes it an important mineral in the lithium industry. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Lepidolite [K(Li,Al)3(Si,Al)4O10(OH,F)2)]is a monoclinic mica group mineral typically associated with granite pegmatites, containing approximately 7% Li2O. Historically, lepidolite was the most widely extracted mineral for lithium; however, its significant fluorine content made the mineral unattractive in comparison to other lithium bearing silicates. Lepidolite mineral concentrates are produced largely in China and Portugal, either for direct use in the ceramics industry or conversion to lithium compounds. |
● | Petalite [LiAl(Si4O10)] contains comparatively less lithium than both lepidolite and spodumene, with approximately 4.5% Li2O. Like the two aforementioned lithium minerals, petalite occurs associated with granite pegmatites and is extracted for processing into downstream lithium products or for direct use in the glass and ceramics industry. |
16.1.1.2 | Lithium Clays |
Lithium clays are formed by the breakdown of lithium-enriched igneous rock which may also be enriched further by hydrothermal/metasomatic alteration. The most
significant lithium clays are members of the smectite group, in particular the lithium-magnesium-sodium end member hectorite [Na0.3(Mg,Li)3Si4O10(OH)2]. Hectorite ores
typically contain lithium concentrations of 0.24%-0.53% Li and form numerous deposits in the USA and northern Mexico. As well as having the potential to be processed into downstream lithium compounds, hectorite is also used directly in aggregate
coatings, vitreous enamels, aerosols, adhesives, emulsion paints and grouts.
Lithium-enriched brines occur in three main environments: evaporative saline lakes and salars, geothermal brines and oilfield brines. Evaporative saline lakes and salars are formed as lithium-bearing lithologies which are weathered by meteoric waters forming a dilute lithium solution. Dilute lithium solutions percolate or flow into lakes and basin environments which can be enclosed or have an outflow. If lakes and basins form in locations where the evaporation rate is greater than the input of water, lithium and other solutes are concentrated in the solution, as water is removed via evaporation. Concentrated solutions (saline brines) can be retained subterraneous within porous sediments and evaporites or in surface lakes, accumulating over time to form large deposits of saline brines.
The chemistry of saline brines is unique to each deposit, with brines even changing dramatically in composition within the same salar. The overall brine composition is crucial in determining a processing method to extract lithium, as other soluble ions such as Mg, Na, and K must be removed during processing. Brines with a high lithium concentration and low Li:Mg and Li:K ratios are considered most economical to process. Brines with lower lithium contents can be exploited economically if evaporation costs or impurities are low. Lithium concentrations at the Salar de Atacama in Chile and Salar de Hombre Muerto in Argentina are higher than the majority of other locations, although the Zabuye Salt Lake in China has a more favorable Li:Mg ratio.

16.1.2 Lithium Industry Supply Chain
Figure 16-1 below shows a schematic overview of the flow of material through the lithium industry supply chain in 2021. Raw material sources in blue and brown represent the source of refined production and TG mineral products consumed directly in industrial applications. Refined lithium products are distributed into various compounds displayed in green. Refined products may be processed further into specialty lithium products, such as butyllithium or lithium metal displayed in grey. Demand from major end-use applications is shown in orange with the relevant end-use sectors in yellow.
Figure 16-1 – Lithium Industry Flowchart (Wood Mackenzie).
Lithium demand has historically been driven by macro-economic growth, but the increasing use of rechargeable batteries in electrified vehicles over the last several years has been the key driver of global demand. Global demand between 2015 and 2021 has more than doubled, reaching 498.2kt LCE with a CAGR of 16.8% over the period. Adding to this growth, in 2022 global lithium demand is expected to increase by 21.3% to 604.4 kt LCE as demand for rechargeable batteries grows further. Over the next decade, global demand for lithium is expected to grow at a rate of 17.7% CAGR to 2,199 kt in 2032.
16.1.3 Global demand for Lithium
Lithium demand has traditionally been used for applications such as in ceramic glazes and porcelain enamels, glass-ceramics for use in high-temperature applications, lubricating greases and as a catalyst for polymer production. Between 2020 and 2022, demand in these sectors rose steadily by approximately 4% CAGR. Growth in these applications tends to be highly correlated to industrial activity and macro-economic growth. Wood Mackenzie forecasts the combined growth of lithium demand from industrial markets is likely to be maintained at approximately 2% per annum from 2023 to 2050.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Rechargeable batteries represent the dominant application of lithium today, representing more than 80% of global lithium demand in 2022. Within the rechargeable battery segment, 58% was attributed to automotive applications which has grown at 69% annually since 2020. This segment is expected to drive lithium demand growth in future. To illustrate, Wood Mackenzie forecast total lithium demand will grow at 11% CAGR between 2023 and 2033: of this lithium demand attributable to the auto-sector is forecast to increase at 13% CAGR; whilst all other applications are forecast to grow at 7% CAGR. Growth is forecast to slow in the following two decades as the market matures (Figure 16-2).
Figure 16-2 – Global Demand for Lithium by End Use, 2030 – 2050 (Wood Mackenzie).
Lithium is produced in a variety of chemical compositions which in turn serve as precursors in the manufacturing of its end use products such as rechargeable batteries, polymers, ceramics, and others. For rechargeable batteries, the cathode, an essential component of each battery cell, is the largest consumer of lithium across the battery supply chain. Demand profiles for lithium carbonate and hydroxide is determined by the evolution in cathode chemistries. The automotive industry mainly uses NCM and NCA cathodes, often grouped together as “high nickel”; and LFP cathodes. High nickel cathodes consume lithium in hydroxide form and generally has a higher lithium intensity; whilst LFP cathodes mainly consume lithium in carbonate form and lithium content is lower. LFP cathodes are predominantly manufactured in China.
Lithium in the form of lithium hydroxide and lithium carbonate collectively accounted for 90% of refined lithium demand in 2022. These two forms are expected to remain important sources of lithium in the foreseeable future reflecting the share of the rechargeable battery market in the overall lithium market (Figure 16-3). The remaining forms of lithium include technical grade mineral concentrate (mainly spodumene, petalite and lepidolite) used in industrial applications accounting for 7% of 2022 demand; and other specialty lithium metal used in industrial and niche applications.

Figure 16-3 – Global Demand for Lithium by Product, 2023 - 2050 (Wood Mackenzie).
Lithium products are classified as ‘battery-grade’ (“BG”) for use in rechargeable battery applications and ‘technical-grade’ (“TG”) which is primarily used in industrial applications. TG lithium carbonate can also be processed and upgraded to higher purity carbonate or hydroxide products.
Lithium hydroxide is expected to experience exponential growth on the back of high-nickel Li-ion batteries. Demand for BG lithium hydroxide is expected to grow at 10% CAGR 2023-2033 to reach 1,133kt LCE in 2033, up from 450 kt LCE in 2023. Wood Mackenzie predict lithium hydroxide to be the largest product by demand volume in the near term. However, growth of LFP demand beyond China may see BG lithium carbonate reclaim its dominance.
Wood Mackenzie forecast LFP cathodes will increase its share of the cathode market from 28% in 2022 to 43% by 2033. This drives growth in lithium carbonates demand. Wood Mackenzie predicts lithium carbonate demand will grow at 14% CAGR between 2023 and 2033; slowing as the market matures.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
16.1.4 Market Balance
The lithium market balance has shown high volatility in recent years. A large supply deficit resulted from historical underinvestment relative to strong demand growth in EVs. The rise in prices over the last few years has incentivized investment in additional supply. However, the ability for supply to meet demand remains uncertain given the persistence of delays and cost increases across both brownfield and greenfield developments.
For BG lithium chemicals, Wood Mackenzie predict the market will remain in deficit in 2024. In 2025, battery grade chemicals are expected to move into a fragile surplus before falling into a sustained deficit in 2033 and beyond. Notably, technical grade lithium chemicals may be reprocessed into battery grade to reduce the deficit. However, capacity and ability to do so is yet unclear.
16.2 Lithium Prices
Lithium spot prices have experienced considerable volatility in 2022 and 2023. Prices peaked in 2022, with battery grade products breaching US$80,000 / t. However, spot prices fell significantly during the Q1 2023 before stabilizing in Q2 2023. A combination of factors can explain the price movements including the plateauing EV sales, slowdown of cathode production in China; and destocking through the supply chain, partially attributed to seasonal maintenance activities and national holidays.
Contract prices have traditionally been agreed on a negotiated basis between customer and supplier. However, in recent years there has been an increasing trend towards linking contract prices to those published by an increasing number of price reporting agencies (“PRA”). As such, contracted prices have tended to follow spot pricing trends, albeit with a lag.
The pricing used in the financial analysis is taken from the WoodMac pricing projections and these are then applied on a weighted basis to the projected production rates of the three key products. These are Prime which exceeds 99.3% Li content, often referred to as Technical grade, Purified product which is often referred to as Battery Grade and exceeds 99.5% Li content. At Olaroz the Purified product greatly exceeds the Battery Grade specifications and, in some contracts, can attract premium payments. A premium is usually applied to Micronised product.
The pricing outcomes are shown in the financial analysis detail.
16.2.1 Lithium Carbonate
Continued demand growth for LFP cathode batteries will ensure strong demand growth for BG lithium carbonate. This demand is expected to be met predominantly by supply from brine projects. Given the strong pricing environment, a large number of projects have been incentivized to come online steadily over the coming years. Wood Mackenzie forecast prices to decline as additional supply comes online. However, Wood Mackenzie forecasts a sustained deficit in battery-grade lithium chemicals to commence from 2031. Over the longer term, Wood Mackenzie expect prices to settle between US$26,000/t and US$31,000 / t (real US$ 2023 terms) (Figure 16-4).
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Figure 16-4 – Lithium Carbonate Price Outlook, 2023 – 2050 (Wood Mackenzie).
Notably, the market for BG carbonates is currently deeper and the spot market more liquid than hydroxide due to the size and experience of its main market of China. In addition, BG carbonates are used in a wider variety of batteries beyond the EV end use. TG lithium carbonate demand for industrial applications is forecast to grow in line with economic growth. However, TG lithium carbonate lends itself well to being reprocessed into BG lithium chemicals (either BG carbonate or BG hydroxide). The ability to re-process the product into BG lithium chemicals will ensure that prices will be linked to prices of BG lithium chemicals.
16.2.2 Lithium Hydroxide
The market for BG lithium hydroxide is currently small and relatively illiquid compared to the carbonate market. Growth in high nickel cathode chemistries supports a strong demand outlook. Most BG hydroxide is sold under long term contract currently, which is expected to continue. However, contract prices are expected to be linked to spot prices and therefore is likely to follow spot price trends albeit with a lag. Over the longer term, Wood Mackenzie expect hydroxide prices to settle at between US$25,000 and US$35,000 / t (real US$ 2023 terms) (Figure 16-5).
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Figure 16-5 – Lithium Hydroxide Price Outlook, 2023 – 2050 (Wood Mackenzie).
16.2.3 Chemical Grade Spodumene
In 2022, demand from converters showed strong growth resulting in improved prices. After years of underinvestment, new capacity has been incentivized and both brownfield and greenfield projects are underway. Notably, these incremental volumes are observed to be at a higher cost and greater difficulty, raising the pricing hurdles required to maintain supply and extending timelines for delivery.
Wood Mackenzie forecast a short period of supply volatility in the years to 2030, moving from surplus to deficit, to surplus before entering into a sustained deficit beyond 2031. Reflecting this dynamic, prices are expected to be in line with market imbalances. Wood Mackenzie forecast a long-term price between US$2,000/t and US$3,000/t (real US$2023 terms) (Figure 16-6).

16.3 | Offtake Agreements |
As of the date of this Technical Report, Allkem has no existing formalized commercial agreements in place for the sale of lithium carbonate from the Sal de Vida Project. Allkem remains in discussions with potential customers. In line with the Project execution schedule, these discussions are expected to advance to negotiations throughout the course of the Project.
16.4 | Risk and Opportunities |
16.4.1 | Price volatility |
Recent pricing history demonstrates the potential for prices to rise and fall significantly in a short space of time. Prices may be influenced by various factors, including global demand and supply dynamics; strategic plans of both competitors and customers; and regulatory developments.
Volatility of prices reduces the ability to accurately predict revenues and therefore cashflows. At present, Allkem’s agreements include index-based or floating pricing terms. In a rising market, this results in positive cashflows and revenues; in a falling market the financial position of the company may be adversely impacted. Uncertainty associated with an unpredictable cashflow may increase funding costs both in debt and equity markets and may therefore impact the company’s ability to invest in future production. Conversely, a persistently stronger pricing environment may also permit self-funding strategies to be put into place.
16.4.2 Macroeconomic conditions.
Allkem produces lithium products which are supplied to a range of applications including lithium-ion batteries, the majority being used within the automotive sector and energy storage systems; industrial applications such as lubricating greases, glass, and ceramics; and pharmaceutical applications. Demand for these end uses may be impacted by global macroeconomic conditions, as well as climate change and related regulations, which in turn will impact demand for lithium and lithium prices. Macroeconomic conditions are influenced by numerous factors and tend to be cyclical. Such conditions have been experienced in the past and may be experienced again in future.
16.4.3 Technological developments within battery chemistries.
The primary growth driver for lithium chemicals is the automotive battery application, which accounts for more than 60% of demand today. Technology within automotive cathodes and cathode chemistries are continuously evolving to optimize the balance between range, safety, and cost. New “Next Generation” chemistries are announced with regularity, which carries the risk that a significant technology could move the automotive sector away from lithium-ion batteries. On a similar note, new technologies could also increase the intensity of lithium consumption. For example, solid state and lithium metal batteries could require more lithium compared to current lithium-ion battery technology. Despite the potential for technological innovations, the impact to the lithium market over the short-medium term is expected to be limited given the extended commercialization timelines and long automotive investment cycles which are a natural inhibitor to rapid technological change.

16.4.4 Customer concentration
Allkem is currently exposed to a relatively limited number of customers and limited jurisdictions. As such, a sudden significant reduction in orders from a significant customer could have a material adverse effect on our business and operating results in the short term. In the near term, this risk is likely to persist. As the battery supply chain diversifies on the back of supportive government policies seeking to establish localized supply, in particular in North America and Europe, there will be scope to broaden the customer base, however the size of automakers, the concentration in the automobile industry and the expected market growth will entail high-volume and high-revenue supply agreements. This risk is closely monitored and mitigative actions are in place where practicable.
16.4.5 Competitive environment
Allkem competes in both the mining and refining segments of the lithium industry presently. We face global competition from both integrated and non-integrated producers. Competition is based on several factors such as product capacity and scale, reliability, service, proximity to market, product performance and quality, and price. Allkem faces competition from producers with greater scale; downstream exposures (and therefore guaranteed demand for their upstream products); access to technology; market share; and financial resources to fund organic and/or inorganic growth options. Failure to compete effectively could result in a materially adverse impact on Allkem’s financial position, operations, and ability to invest in future growth. In addition, Allkem faces an increasing number of competitors: a large number of new suppliers has been incentivized to come online in recent years in response to favorable policy environment as well as higher lithium prices. The strength of recent lithium price increases has also incentivized greater investment by customers into substitution or thrifting activities, which so far have not resulted in any material threat. Recycling will progressively compete with primary supply, particularly supported by regulatory requirements, as well as the number of end-of-life battery stock that will become available over the next decade as electric vehicles or energy storage systems are retired.

16.5 | Conclusion |
Wood Mackenzie, also known as WoodMac, is a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries. It is the opinion of the employee of Gunn Metallurgy that the long-term pricing assessment indicated in this section is deemed suitable for economic assessment of the Project at the current level of study.
The pricing is based upon the projections of production for the three product types, Prime (close to battery grade specification), Purified (exceeds battery grade) and Micronized. It is universally accepted by banks, investors and knowledgeable industry commentators and consultants at this time that demand will outstrip supply in the next few years. The employee of Gunn Metallurgy is confident that the pricing of lithium products in the near term is not a challenge to the viability of the project. The medium to long term lithium product pricing is not considered to be predictable in the current dynamic and changeable ecommerce industrial environment that determines demand forces.
16.6 | Recommendations |
Market analysis will continue to evolve during the project development phase. It is recommended that Allkem continue with ongoing market analysis and related economic sensitivity analysis.
Risk factors and opportunities in technological advancements, competition and macroeconomic trends should be reviewed for relevancy prior to major capital investment decisions. Remaining abreast of lithium extraction technology advancements, and potential further test work or pilot plant work may provide opportunities to improve the Project economics.
It is recommended to further develop diversified customer base and secure off take agreements to support the next study phase and potential expansion.

17.4 | Environmental Baseline Studies |
Environmental baseline studies were carried out in the Salar del Hombre Muerto area over a number of field seasons starting in 1997. The baseline study area has changed over time as the Project footprint has changed.
● | The total water catchment area for Salar del Hombre Muerto is approximately 3,929 km2. The main perennial streams entering the Hombre Muerto basin salar are the Trapiche River and the Los Patos River, both of which enter from the south and come from two different basins. Estimated total surface water flow to the salt pan is 147 x 106 m3/year. The natural chemical composition of the Los Patos River is brackish and is not suitable for human consumption. |
● | Water Balance: The following elements can be summarized regarding the baseline water balance (Montgomery & Associates, 2020) and recharge estimates: |
○ | The average rainfall on the basin is 107 mm/yr, or about 9,150 l/s. |
○ | The total snow precipitation estimated amounts to 61 mm/yr, of which 39 mm/yr are lost to sublimation and 22 mm/yr are snowmelt. |
○ | Total precipitation basin is 129 mm/yr, or about 11,050 L/s. Recharge in basins similar to Salar del Hombre Muerto has been estimated to range from 5% to 20% of its volumetric precipitation; therefore, the initial estimated recharge range is approximately 550 l/s to 2,200 l/s. |
○ | The evaporation discharge estimated from the 2014-2019 satellite images is 1,005 l/s for the low evaporation scenario, 1,708 for the medium evaporation scenario, and 2,697 for the high evaporation scenario. |
○ | Given that satellite images were only available for a six-year period (2014-2019), the evaporation estimate was adjusted by a long-term correction factor of 0.85 based on the relationship between long-term and 2014-2019 precipitation, assuming that evaporation is proportional to precipitation. After this correction factor was applied, the following long- term evaporation estimates were obtained: 850 l/s, 1,500 l/s, and 2,300 l/s for the low, medium, and high evaporation scenarios, respectively. |
○ | The higher evaporation estimate is slightly larger than the upper bound of the precipitation recharge estimate (2,200 l/s). The lower bound of the precipitation recharge estimate (550 l/s) is significantly inferior to lower evaporation estimate (~850 l/s). An estimated average recharge rate for the basin would then be in the range of 850 l/s to 2,200 l/s. |
○ | The current best estimate for recharge is considered 1,500 l/s; however, whenever the recharge estimate is used, we recommend running a sensitivity analysis for recharge rates as low as 850 l/s, or as high as 2,200 l/s. If these sensitivity analyses identify a risk, then a more focused investigation could be required to assess the chance of a having a recharge below or above a specific value (Montgomery, 2020). |

SEC Technical Report Summary
17.4.1 Water Quality
17.4.1.1 | Surface Water Quality |
Surface water sampling campaigns commenced with the 2011 environmental baseline studies at five locations which included one site in the Río de los Patos and one site in each of the Laguna Verde, Vega de Hombre Muerto, Vega de las Ignimbritas, and at the mouth of the Laguna Catal (ERM, 2011). In 2011, samples were taken from areas with no evidence of any type of disturbance and were representative of the baseline in the study area. Results indicated that the water samples had high levels of sulphates, chlorides, boron, arsenic, lithium, TDS. Since 2009 to quarterly water campaigns have been carried out in Los Patos basin river; high arsenic is considered typical of the Puna area.
The evaluation of the historical hydro chemical data confirmed the classification of the water as a sodium chloride type.
17.4.1.2 | Groundwater Quality (Freshwater Wells) |
Groundwater quality was first sampled in 2012 during the water well drilling program and has been continuously monitored until now. This water is used as raw water for the construction and mining activities. However, it is not potable and is treated via a reverse osmosis (RO) treatment plant that produces potable water.
The groundwater samples were classified as sodium chloride. The predominant anions were chlorides, and the main cations were Na+ and K+.
TDS values were lower in groundwater than the ones in surface water.
17.4.1.3 | Groundwater Quality (Brine Semiconfined and Confined Deep Aquifer): |
This water quality is discussed in Sections 7 and 15 as it is related to the resource/reserve for the Project.
17.4.1.4 | Water Monitoring Program |
Current water monitoring program includes streamflow, groundwater level, field water quality parameters major anions and cations and trace metals. Water quality is sampled quarterly, while field parameters and streamflow levels are measured monthly. This frequency was irregular during the last two years because of pandemic restrictions. According to the agreements acquired in the 2021 DIA, the monitoring at sites SV-M4, -M10 and -M11 are conducted with the participation of the local community. From SV-M1 to SV-M5 is measured streamflow and surface water quality and from SV-M10 (SVFW12_19) to SV-12 (SVFW21_21) shallow aquifer levels and field parameters.

17.4.2 Air Quality
The parameters evaluated were found in low concentrations in accordance with favorable atmospheric dispersion conditions and limited anthropic activity in the study area.
The last air quality and environmental noise monitoring, which was conducted in December 2022, showed results below the limits established by Law 24.585 for mining activities, for all five sites sampled.
17.4.3 Soils
Soils are generally alkaline in character, especially in the salt pan. Interpreted as being due to the higher concentration of ionic elements supplied by the phreatic water in the salt pan. There is a low level of organic matter in the samples. Where high nitrogen content is found, this corresponds to the organic composition of black, fetid clay. There is a strong concentration of calcium and sodium in the superficial horizon located on the margins next to the salt pan, decreasing in the deeper horizons of the soil profile. No hydrocarbons were detected in any of the samples taken during the 2011 baseline studies. The absence of heavy metals anomalies in the waters implies their absence as well as in the soils affected by them.
17.4.4 Biodiversity Baseline Studies & Monitoring Conducted
The Project is located in the Central Andean Dry Puna Ecoregion. This 118,000 km2 ecoregion occurs between 3,500 to 5,000 m elevation and is characterized by cold temperatures and aridity, with precipitation 3400 mm per year. Vegetation includes grassy and shrubland steppe habitats. Other habitats include streams, rivers, bofedales (bogs), Vegas, lakes and salt flats. Wildlife characteristics of the ecoregion include vicuna, puma, Andean cat, Andean fox, and three species of flamingo. Endemic plant and animal species are also present. Centuries of livestock grazing, and firewood collection have degraded the Puna but it is considered by World Wildlife Fund as “relatively stable/intact”.
Baseline studies and monitoring reports are available for the SDV project, including the ERM 2011. Environmental and Social Baseline study and several monitoring campaigns carried out in recent years by Knight Piesold (since August 2020, May2023). The 2011 ERM assessment randomly sampled various taxonomic groups and plant communities across the entire project area. The subsequent Knight Piesold monitoring campaigns were more comprehensive and focused on what are considered to be the habitats of highest biodiversity value across the eastern Salar del Hombre Muerto and the Los Patos River basin. These studies provided the basis for the identification of biodiversity values in the vicinity of the Project and supported a Critical Habitat Assessment. In the future as more monitoring campaigns are completed, a better understanding of the variability of biodiversity values both spatially and temporally will be gained (SRK, 2022). Assessments conducted in March 2021 by Knight Piésold Consulting identified only the presence of rainbow trout specimen and no other species of fish were recorded.

SEC Technical Report Summary
17.4.5 Limnology
Since March 2020 to May 2023 baseline studies highlighted the ecological value of the macroinvertebrates that inhabit aquatic lotic ecosystems such as the Río de los Patos since they process organic matter and serve as food for other organisms, such as fish or amphibians. Supplementary studies of the limnological Baseline for the area of influence of the Sal de Vida Project performed by Knight Piésold , made it possible to characterize the taxonomic assemblages of phytobenthos, zooplankton, phytoplankton, and aquatic macroinvertebrates in wetland bodies. Shallow and hypersaline water bodies condition the limnological composition to less richness and abundance of organisms, where species of the Bacillariophytes and Cyanobacteria taxa predominate. In the water bodies with better chemical quality or less saline concentration, macroinvertebrates predominate, and zooplankton are much more abundant.
17.4.6 Ecosystem Characterization
The area of the Sal de Vida Project covers two Phytogeographic Provinces of the Andean Domain: Puna and Altos Andes (Cabrera, 1976). The climate is cold and dry, with very strong winds and precipitation in the form of snow or hail in any season of the year. In general, the higher peaks have permanent snow coverage. The average annual temperature is 3.1°C and the mean monthly temperatures tend to be below freezing for more than half the year; the solar radiation is high, and the thermal amplitude is very large. During 2021, two wetland monitoring campaigns were carried out in the salar basin in order to define the main characteristics of the most fragile ecosystems called Vegas, some of which provide ecosystem services to the local community of Ciénaga Redonda (Table 17-1).
17.4.7 Landscape
The dominant landscape is extensive alluvial and salt flats. The main landscape modelling agents are river run-off and wind action, generating both erosion and accumulation geo-forms. The salar has superficial salt crusts and shallow superficial lagoons. The visual quality is favored by the scenic background, especially in those units of landscape in which steep mountain ranges stand out in different perspectives, with unique elements such as high-altitude hills like the Ratones volcano and the Ciénaga mountain range. There are natural landmarks that increase the visual quality of the landscape, such as the Los Patos River and its delta, meadows, streams, as well as positive cultural landmarks like the Ciénaga Redonda hamlet.

17.4.8 Socioeconomic Setting
The department of Antofagasta de la Sierra is located to the west of the province, 580 km from the capital city of San Fernando del Valle de Catamarca, while the distance between the provincial capital and the head of the department is 608 km. The department consists of the localities of Villa de Antofagasta, El Peñón, Los Nacimientos, el Salar del Hombre Muerto, Antofalla, Las Quinuas, Ciénaga La Redonda, Paraje La Banda, Vega de la Laguna and Río la Punilla. According to the Municipal Census (2018) it has 1,684 inhabitants, with a density of 0.6 inhabitants/km2. The type of population is rural grouped: 72.7%, rural dispersed: 27.3%.
17.4.9 Archaeology
The 2011 baseline studies provided an archaeological profile of the study area and a reference framework at a regional level, upon which it would be possible to compare and integrate results of future surveys carried out for infrastructure works programmed in the framework of ongoing projects. The Stage 1 area was covered by the 2020 – 2021 archaeological baseline studies (see Table 17-1) and the Stage 2 Project area was studied in the 2022 and June 2023 Geology and geomorphology: Covered in Section 7.

17.4.10 Mining Waste
The Project will generate discarded salts and liquid waste during the process, mainly brines, which are not expected to represent a contamination risk. This liquid waste will be sent to the waterproofed waste/discard disposal facilities. The Project does not require a tailings storage facility.
This waste/discard disposal facility will consist of halite stockpiles, muriate stockpiles and co-disposal stockpiles surrounding the halite ponds. The facility will cover a total area of approximately 402 300 ha for Stages 1 of the Project. The salt piles will average 30 m in height and will be built principally on the salt pan surface. Further details on waste/discard disposal can be found in Chapter 14.2.4 – Waste Disposal.
The salts are generated from brines already present in the salt flat and do not introduce foreign compounds to it. Basically, they are composed of sodium chloride (common salt), potassium chloride, sodium and calcium sulphates, magnesium hydroxide and boron. It is estimated that sodium chloride and sulphate make up over 94% of this waste.
The main process waste/discards will include:
● | Solid discards from the evaporation ponds: these will comprise harvested salts from the halite and muriate ponds. These salts will be generated from around Year 2 of production, since the salt layer and harvestable layer must be in place at the base of each pond before the first harvest can be undertaken. |
● | Solid-liquid waste/discards from the process plant: |
● | Liming solid discards: primarily precipitated magnesium hydroxide, borate salts and gypsum. |
● | Softening solid discards: primarily precipitated calcium carbonate and magnesium carbonate. |
● | Mother liquor that is not used in the process: a portion of the mother liquor generated from the primary lithium carbonate plant will be discarded since it is not required in the process. |
● | RO plant retentate (reject). |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Steam boiler retentate. |
● | Any sump pump solutions that cannot be recycled within the process. |
All waste/discards will be disposed as follows:
● | Co-storage of solids and liquids: the co-storage area will be around the halite ponds for both process plant discards/wastes and harvested halite salts. It will consist of an area of approximately 402 ha. |
● | Since the generation of solid-liquid discards from the process plant begin before the harvesting of any salts from the pond, these discards will be treated differently during the first two years. During the first two years all, liquid discards generated from the process will be sent to an event pond, which will be located near the process plant. After Year 2 of production, the event pond will only be used for unprogrammed events. All solid discards will be sent to de co-disposal area, to be stockpiled in the harvested salts storage area. From Year 2 of production onward, the solid salts harvested from the halite evaporation ponds will be sent to the same co-disposal area and will be deposited around the initial 2 years of solid stockpile built up to that date, generating a containment dam. From Year 2 of production onward, both liquid and solid waste from the process plant will be mixed in a tank located near the process plant and sent as a pulp (or slurry stream) to the co-disposal area, to be co-disposed in the containment dam within the halite salts. This will operate for the remainder of the Project life. |
● | Halite stockpile: not all harvested halite salts will be sent to the co-disposal area. Some halite salts will be stockpiled separately to be used as construction material for future evaporation ponds. These salts will be sent directly to the halite stockpile area by truck after being harvested, to be stockpiled accordingly. The total area available for the halite stockpile will be 20.8 ha. |
● | Muriate stockpile: all muriate salts that are harvested will be stockpiled separately. These salts will be sent directly to the muriate stockpile area by truck after being harvested, to be stockpiled accordingly. The total area available for the muriate stockpile will be 46.3 ha. |
● | The infrastructure of these areas (stockpiles of harvesting salts) will include mainly of access roads on ramps and systems of containment, such as low-height berms at the base, to retain slurry effluents that can filter from salt stockpiles. In addition, the entire bases of the harvesting salts piles will be waterproofed with 1mm thick HDPE geomembrane. |
● | The Environmental Control Program (PCA) for of the Process Waste Management is a legal requirement (DIA 2021) which was submitted to Mining Authority for approval. |
17.5 | Permitting |
17.5.1 | Environmental Impact Assessment Permit |
Within the Argentinian regulatory framework, the Environmental Impact Assessment Report (EIA) allows for one to obtain a Declaration of Environment Impact (DIA), which is the legal instrument that governs all of a Project’s exploration, construction, and exploitation activities, and it must be updated every 2 years (Article 11 of Federal Law No. 24.585). The Sal de Vida Project has an approved DIA, Resolution 2021-781- E-CAT-MM, which enables the Project to construct and operate within the constraints of the issued permit. This approval is included in Allkem’s DIPGAM file E4220/2013 (Allkem’s file with the Secretary of Mining of the Province of Catamarca) for the proposed Sal de Vida operations.

SEC Technical Report Summary
17.6.1 Environmental Insurance
Environmental insurance requirements are prescribed by Argentinian National Law No. 25.675 and by Resolution No. 19/12 by the Secretariat for the Environment and Sustainable Development of Catamarca. This resolution requires mandatory insurance coverage, sufficient to guarantee the financing of any environmental remediation. The insurance must be in place to obtain any related permits, authorizations, registrations, and Environmental Impact Statements. It is an essential requirement for the issuance of certain permits, such as the National Hazardous Wastes registration (Blue Pampa, 2019).
Allkem has insurance (Mandatory Environmental Insurance- SAO) for all early work activities and has extended its coverage to coincide with the ongoing construction activities. Insurance coverage is reviewed annual and adjusted to suit ongoing Project activities.
17.6.2 Environmental Liabilities
The Project is not subject to any known environmental liabilities. There has been active ulexite mining within the boundaries of the existing land agreement, but the operations are limited to within 5 m of the surface and will naturally be reclaimed fairly quickly once mining has halted (Houston and Jaacks, 2010).
17.7 | Social and Community Considerations |
17.7.1 Project Setting and Social Baseline Studies
The original sociocultural baseline was conducted in 2011 (ERM, 2011). In 2018, the National Council for Scientific and Technical Research (CONICET), in conjunction with the University of Salta, conducted a social survey in the Ciénaga La Redonda community immediately to the east of the Project area. In 2020, an update of the social baseline and social perception study were carried out, then in 2022 the company carried out a complementary social baseline which emphasized the inhabitants of the Salar del Hombre Muerto.
In the area of the Salar de Hombre Muerto there are five population centers: Antofagasta de la Sierra and Ciénaga La Redonda in the Province of Catamarca, and Pocitos, San Antonio de los Cobres and Santa Rosa de los Pastos Grandes in the Province of Salta. (ERM, 2011). The closest settlement to the Project is Ciénaga La Redonda, which is approximately 5 km by road from Allkem Sal de Vida’s Tango 01 camp. Allkem Sal de Vida updated the social reference report by carrying out the following studies:
● | A complementary social baseline (2022) |
● | Previously in 2020 Sal de Vida performed: |
○ | A social perception survey with local communities. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
○ | A new socioeconomic baseline based on the 2011 ERM report. |
○ | A survey of local suppliers, particularly in the Province of Catamarca. |
○ | A study of local competencies in the area of direct influence and the Province of Catamarca. |
17.7.2 Socioeconomic Aspects
The department of Antofagasta de la Sierra is made up of the towns of El Peñón, Antofalla, Los Nacimientos, Ciénaga Redonda, and Antofagasta Villa, which are dispersed rural towns. Currently there are 1,684 inhabitants in the entire department (Municipal Census 2018). Villa de Antofagasta is the departmental head, being a single third-category municipality. The Municipality does not have a Deliberative Council or Municipal Charter. The population is rural, 60.1% resides in Villa de Antofagasta, the rest is distributed in the aforementioned localities.
The age structure of the population shows a particular concentration of inhabitants in the central active ages, namely, 25 - 29 and 30 - 34 years; This concentration is more accentuated in the male population than in the female population, which is attributed to a phenomenon of population attraction associated with the development of mining activity in recent years.
We can recognize two emigration processes in the department, both on a small scale. On the one hand, there is seasonal family migration between the months of June and August associated with climatic reasons towards Belén and the provincial capital. On the other hand, there is the migration of young people to the provincial capital, Belén or Salta for study purposes. However, few families can bear the economic costs of having one of their members in another jurisdiction.
According to the 2010 Census, the percentage of households with Unsatisfied Basic Needs (UBN) in the department is 17.5%, compared to 11.4% at the provincial level and 9.2% at the national level. Regarding the quality of the dwellings, almost all of them (97.8%) have an insufficient quality and only 2.2% have a satisfactory quality. In general, connections to basic services are insufficient. According to the 2010 Census, only 30.3% of the dwellings in the department are connected to the sewage system. The rest of the inhabitants have septic tanks.
The school term in the department begins on August 20 and lasts until mid-June, with a school break at the end of the year. In total, the department has 3 preschools, 5 primary schools, and 3 secondary schools. In 2021 Allkem Sal de Vida contributed to the communities of Antofagasta de la Sierra with the construction of two schools: Secondary School No. 27 in El Peñon and the expansion of Primary School No. 494 in Villa de Antofagasta.
Antofagasta de la Sierra has a low-risk care hospital with single hospitalization. In the districts there are health posts run by nurses or health workers.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Outside the mining sector, opportunities for qualified formal employment with wages above the minimum wage are scarce. Thus, the development of self-employed activities or family businesses in services and commerce is limited by the restricted purchasing power of a large part of the families in the population, as well as by the absence of credit options adapted to the local reality.
In the last three years, a boost has been given to local development initiatives and expectations of improving the quality of life, attributed to the development of mining activity and the associated royalty system. The improvements can be seen mainly in the area of public works and access to basic services.
Municipal employment absorbs about 70% of the municipal budget. If this figure is considered in percentage terms, it is possible to estimate that around 47% of the economically active population works as a municipal employee.
Since 1990, mining has begun to gain momentum in the department, becoming the main economic activity of the private sector.
Tourism is the second most important economic activity in the private sector. Its development is based on the initiatives of extra-local tourist guides and the private ventures of local families that have created lodgings, restaurants, diners, and craft shops.
Livestock is an important source of family support for households in the department. The production of sheep and camelids is the most important and, second place, goats.
17.7.3 Indigenous Communities
In Antofagasta de La Sierra, there are two indigenous communities, as described below.
Kolla-Atacameña de Antofalla Community: it is the only native community officially recognized within the department of Antofagasta de la Sierra by Resolution No. 158 of the National Indigenous Institute (INAI), issued on May 4, 2007. It is made up of 60 people. According to the information provided by the Cacique of the Community, 45 of them reside in Antofalla, while another 15 members are scattered in the vicinity of the territory, in houses called “stone huts”.
The internal organization system of the Kolla-Atacameña de Antofalla community is made up of a Cacique, the Council of Elders (made up of a total of 18 people, including men and women), an administrator, a treasurer, a delegate from the North and a South delegate. All these authorities are elected in an open assembly every two years. At the time of the survey and given the health emergency decreed at the national level as a result of COVID 19, the assembly to elect the new cacique had not yet been held in Antofalla. The term is two years.
Community members do not have individual title to the land. The land is managed by the community and has been endorsed by national regulations (INAI). It is precisely on this premise that the community consultation processes are based, which are carried out prior to the implementation of any mining project. Although each family or individual owns their own land, it is not formally demarcated.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Mining activity is strongly established in the Antofalla community and constitutes, together with tourism, the main source of employment for the population. Even before the arrival of the mining companies, there was a strong “mining culture” due to the artisanal development of this activity (mainly gold and silver mining).
Atacameños del Altiplano Community: In the Salar del Hombre Muerto there is an identity emergency process that corresponds to the creation of an indigenous community called “Atacameños del Altiplano”. This native community still does not have legal status or technical or legal cadastral studies, its formation is in process, the community has submitted documentation to the INAI during 2020 and is awaiting the resolution. The community is made up of a small number of people, some from Ciénaga Redonda and families from places in the Salar del Hombre Muerto.
Sal de Vida currently works actively with the two indigenous communities through the implementation of solid community programs for the inclusion of indigenous peoples (infrastructure projects, training, health and well-being, etc.).
17.7.4 Identification of Social Risks and Opportunities
It is expected that there will be both positive and negative social impacts from the Sal de Vida Project on the surrounding communities. A potential negative impact could be the influx of new people to the area and its effect on public infrastructure and resources, such as housing, clinics, schools, municipal services, and the potential to affect local cultural values. The growing activity derived from the construction and operation of the Project will have a positive impact on the revitalization of the local and regional economy. Local communities in the area of influence will be able to access jobs with social benefits, medical services, retirement contributions and good contracting conditions.
As part of the social commitments and compliance with the requirements established by the Catamarca Mining Authority, Allkem Sal de Vida has been working with the government on community participation programs designed to:
● | Train and improve the skills of people from local communities. |
● | Prioritize the hiring of local operators and technicians in the area of influence. |
● | Work with the University of Catamarca and technical schools to develop professionals for future positions. |
● | Consider gender and diversity perspectives in the processes of hiring local labor and in community projects. |
Sal de Vida Lithium Brine Project

● | Strategic Communication Program |
● | Program to Strengthen Livestock Farming for Local Rural Producers |
● | Indigenous Peoples Program |
● | Stakeholder Participation Program |
● | Intangible Cultural Heritage Strengthening Program |
● | Instructions for Good Practices in the Community |
The programs establish commitments that include deadlines and schedules as appropriate and that are aligned with Allkem Sal de Vida’s four-pillar approach to social initiatives and projects within its sustainability framework, namely education and employment, sustainable development and culture, health and wellness and infrastructure.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The Sal de Vida Project has also defined a territorial community management approach. This approach specifies the following points:
● | Open door communication policy with the community. |
● | Early and constant contact and relationship with institutions, organizations, and the community in general. |
● | Identification and characterization of communities, idiosyncrasies, mapping of social actors, survey of common social problems. |
● | Early response to inquiries and claims. |
● | During 2021 Allkem Sal de Vida completed important works in Ciénaga Redonda for the benefit of its inhabitants: construction of a first aid post, construction of a sports field, construction and improvement of sanitary facilities, implementation of water heaters with solar panel technology and has implemented a successful training program that was developed in all the communities of the department of Antofagasta de la Sierra. The training program was designed and established so that the inhabitants near Sal de Vida can be trained in issues of the lithium industry and thus acquire skills that allow them to have job opportunities within the Sal de Vida Project. |
Since 2021, Sal de Vida has been developing a “Completion of Education” program that benefits project collaborators, the communities of Ciénaga Redonda and Antofalla. This program is carried out jointly through an agreement signed with the Ministry of Education of Catamarca. Allkem aims to support local communities by maximizing health, well-being and the acquisition of local goods and services while upskilling and providing future employment opportunities. During CY21, Allkem undertook a number of initiatives including:
● | Industrial technical training program in Antofagasta de La Sierra, carrying out more than 43 courses attended by more than 600 people. |
● | The development of local suppliers in Antofagasta de La Sierra, establishing a local laundry service for the Sal de Vida project. |
● | Implementation of Health and Well-being Days in the towns of Antofagasta de la Sierra, which involved talks by medical professionals on the prevention and care of different conditions and pathologies in all communities. |
As of March 31, 2022, more than 70% of local employees are from Catamarca and Stage 1 will create approximately 900 full-time positions at peak construction and 170 full-time positions during stable Stage 1 operations.
Engagement with the provincial government and stakeholders, including the Antofagasta de La Sierra communities, regarding project updates continues.

17.7.5.1.1 Successful Community Programs Period 2022 - 2023
IMPLEMENTATION PROGRAMS OF UNIVERSITY TECHNIQUE IN LITHIUM BRINE
Background: It is observed that in the Antofagasta de La Sierra department there is no tertiary and/or university educational proposal.
Proposal: Framework Agreement between the Faculty of Technology of the National University of Catamarca, the Municipality of Antofagasta de La Sierra, and the company Allkem Sal de Vida, for the implementation of University Technique in Lithium Brines. In May 2023, the first year (of three) of the Brine Technician completed successfully, to resume the second year in September 2023.
Alliances: Faculty of Technology of the National University of Catamarca, Municipality of Antofagasta de La Sierra, and Allkem Sal de Vida.
Indicators and achievements: Number of people from the communities in the training process: 14 people.
STRENGTHENING PROGRAM FOR LOCAL RURAL PRODUCERS
Within the framework of the development of Community Productive Projects carried out by Allkem SDV during the second semester of 2023 and the first semester of 2024, a Rural Community Strengthening Program was developed, with the objective of benefiting rural producers in the department of Antofagasta de La Sierra.
Background: The Antofagasta department is in the middle of the Catamarca puna, characterized by altitudes that vary between 4,600 and 3,200 meters above sea level, registering extreme temperatures of -30 °C. Its characteristic arid Puno climate does not allow for extensive agricultural development, which is why local producers resort to farming practices in small plots and/or in fertile plain areas, as well as small greenhouses. Of the production generated, a small percentage is for local sale, the rest is distributed for family consumption and animal fodder to a lesser extent.
Proposal: Based on the survey of a professional external agronomist consultant from CSR SDV, potential development paths are identified to strengthen family farming practices based on:
● | Incentive, technical monitoring of new crop varieties |
● | Improvement of infrastructure for crop irrigation. |
● | Technical advice for agricultural improvement (incorporation of technology in production) |
● | Technical advice for animal health |
● | Implementation of greenhouses |
● | Technical advice for the sale of agricultural and livestock products (processing in municipal, provincial, and national organizations). Key points of the chain by local collectors. |

The closure plan scope will include Sal de Vida facilities at the mine site as well as all associated offsite infrastructure.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The Project has an estimated life of mine (LOM) of 40 years. It is expected that closure and post-closure monitoring activities will continue for a minimum of five years from the end of the operation phase. Most of the closure activities will be carried out at the end of the mine operation phase; however, it is possible that some activities will be carried out in parallel with the operation stage as concurrent closure. Once the closure activities have been executed, a minimum period of seven years of post-closure environmental monitoring will continue, before definitive closure is achieved. The removal of access roads to the pond and waste pile areas will occur at the end of the monitoring period.
The cost for remediation is indicated in Section 18 and includes for remediation and reclamation activities at the end of Life of mine (LOM).
17.9 | Conclusions |
The project has fulfilled the required environmental and social assessments to progress into construction of Stage 1. The project is permitted by the provincial mining authorities and has provincial and federal permits.
The project reflects positive social and socio-economic benefits for local communities.
Expansion Stage 2 permitting application process is still to commence.

18. | CAPITAL AND OPERATING COSTS |
The Qualified Person for this chapter is the employee of Gunn Metallurgy, outlining the capital and operational costs for Sal de Vida. Every cost forecast is delineated on a yearly basis for the Sal de Vida life of mine.
Sal de Vida stands as a project, and the capital cost does not consider expenditures that have already been absorbed by Allkem in the prior development phases, also called as sunk cost. Furthermore, ongoing outlays unrelated to the direct Sal de Vida project.
All estimates outlined herein are expressed in FY2024 prices. All projections are estimated in real terms, and they do not incorporate allocations for inflation, financial expenses and all financial assessments are expressed in US dollars.
Capital and operating cost estimates for Stage 1 were prepared using AACE International guidelines. The Stage 1 wellfield, brine distribution, evaporation ponds, waste (wells and ponds) and Stage 1 process plant capital and cost accuracy is ±10% with a contingency less than or equal to 10% as defined by the SK Regulations, with remaining uncertainty associated with an expected 40-year life of mine.
18.1.1 Basis of Capital Cost Estimate
The Sal de Vida Project Stage 1 overall construction progress reached 24% completion in June 2023. As of July 2023, the project achieved Well & Brine distribution and Pond Strings 1&2 Completion and is progressing towards finishing the construction camp to its full capacity. The Capital expenditures for Sal de Vida Stage 1 were estimated for a plant capacity of 15,000 tonnes of lithium carbonate per year.
The estimate includes capital cost estimation data developed and provided by Worley, Allkem, and current estimates for completion for Stage 1.
The capital cost was broken into direct and indirect costs.
18.1.1.1 Direct costs

18.2.1.4 Taxes, Royalties, and Other Agreements
Catamarca Province Law 4757 requires provincial royalties that are generally limited to 3% of the mine head value of the extracted ore, calculated as the sales price less direct cash costs related to exploitation and excluding fixed asset depreciation. On December 20, 2021, Allkem and the Province of Catamarca executed a Royalties Commitment Deed, pursuant to which Allkem is to pay to the Province of Catamarca a maximum amount of 3.5% of the “net monthly revenue” from Sal de Vida Project. This royalty is inclusive of the standard provincial royalty and includes a 0.03% corporate sustainability contribution. In addition, pursuant to Federal Argentine regulation Decree Nr. 1060/20, a 4.5% export duty on the FOB price is to be paid when exporting lithium products.
18.2.1.5 Employee Benefit Expenses
Allkem developed a detailed proposed organizational chart and salary plan for the entire Project. Salaries were based on current actual costs, with a 25% uplift for market positioning and an attraction/retention factor for the number of personnel required for the first year of operations.
The operations will use the following work rotation, depending on the operational area:
● | 14 days on/14 days off: this work rotation would be based on fourteen days on-duty and fourteen days off- duty, with 12-hour shifts per workday, and would be applicable for staff at site. |
● | 5 days on/2 days off: this work rotation would be based on a Monday-to-Friday schedule, 40 hours per week, and would be applicable only to personnel at the Catamarca city office. |
18.2.1.6 Operation Transports
The Sal de Vida Project is located approximately 1,400 km northwest of Buenos Aires, Argentina, within the Salar del Hombre Muerto in the Province of Catamarca, 650km from the city of Catamarca via Antofagasta de la Sierra and 390 km from the city of Salta via San Antonio de los Cobres.
Pricing for transportation and port costs were obtained from budgetary quotations and are based on 30t trucks, the maximum load allowed in Argentina. The estimate includes freight, handling, depot, and customs clearance to deliver lithium carbonate FOB Angamos (Chile).
The transportation approach considers a storage facility at the port to supply a buffer for shipments against disruption events such as road blocks, strikes, production, etc. Approximately 120 t of lithium carbonate will be trucked to port each day, equivalent to just over four trucks per day. During operations, transport strategy optimization opportunities in truck movement of reagents and finished product will be considered, such as backhaul opportunities.

19. | ECONOMIC ANALYSIS |
This section analyzes the Sal de Vida Project Stage 1 economic feasibility. Certain information and statements contained in this section and in the report are forward-looking in nature. Actual events and results may differ significantly from these forward-looking statements due to various risks, uncertainties, and contingencies, including factors related to business, economics, politics, competition, and society.
19.1 | Forward Looking and Cautionary Statement |
Forward-looking statements cover a wide range of aspects, such as project economic and study parameters, estimates of Brine Resource and Brine Reserves (including geological interpretation, grades, extraction and mining recovery rates, hydrological and hydrogeological assumptions), project development cost and timing, dilution and extraction recoveries, processing methods and production rates, metallurgical recovery rate estimates, infrastructure requirements, capital, operating and sustaining cost estimates, estimated mine life, and other project attributes. Additionally, it includes the assessment of net present value (NPV) and internal rate of return (IRR), payback period of capital, commodity prices, environmental assessment process timing, potential changes in project configuration due to stakeholder or government input, government regulations, permitting timelines, estimates of reclamation obligations, requirements for additional capital, and environmental risks.
All forward-looking statements in this Report are necessarily based on opinions and estimates made as of the date such statements are made and are subject to important risk factors and uncertainties, many of which cannot be controlled or predicted. Material assumptions regarding forward-looking statements are discussed in this Report, where applicable. In addition to, and subject to, such specific assumptions discussed in more detail elsewhere in this Report, the forward-looking statements in this report are subject to the following general assumptions:
● | No significant disruptions affecting the project’s development and operation timelines. |
● | The availability of consumables and services at prices consistent with existing operations. |
● | Labor and materials costs consistent with those for existing operations. |
● | Permitting and stakeholder arrangements consistent with current expectations. |
● | Obtaining all required environmental approvals, permits, licenses, and authorizations within expected timelines. |
● | No significant changes in applicable royalties, foreign exchange rates, or tax rates related to the project. |
To conduct the economic evaluation of the project, Allkem’s team employed a cash flow model that allows for both before and after-tax analysis. The main inputs for this model include the capital and operating cost estimates presented in the previous chapters, along with an assumed production program based on the plant performance capability and the pricing forecast outlined in Section 16.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Using the cash flow model, it has been calculated the key project’s indicators, including a sensitivity analysis on the most critical revenue and cost variables to assess their impact on the project’s financial metrics.
19.2 Evaluation Criteria
For the economic analysis, the Discounted Cash Flow (DCF) method was adopted to estimate the project’s return based on expected future revenues, costs, and investments. DCF involves discounting all future cash flows to their present value using a discount rate determined by the company. This approach facilitates critical business decisions, such Merger & Acquisition (M&A) activities, growth project investments, optimizing investment portfolios, and ensuring efficient capital allocation for the company.
Key points about the Discounted Cash Flow method:
● | The discount rate is based on the weighted average cost of capital (WACC), incorporating the rate of return expected by shareholders. |
● | All capital expenditures incurred to date for Sal de Vida Project were considered as sunk costs and excluded them from the present value calculations. |
The DCF approach involves estimating net annual free cash flows by forecasting yearly revenues and deducting yearly cash outflows, including operating costs (production and G&A costs), initial and sustaining capital costs, taxes, and royalties. These net cash flows are then discounted back to the valuation date using a real, after-tax discount rate of 10%, reflecting Allkem’s estimated cost of capital. The model assumes that all cash flows occur on December 31st, aligning with Allkem’s Fiscal Year.
The DCF model is constructed on a real basis without escalation or inflation of any inputs or variables. The primary outputs of the analysis, on a 100% Project basis, include:
● | NPV at a discount rate of 10%. |
● | Internal rate of return (IRR), when applicable. |
● | Payback period, when applicable. |
19.3 | Financial Model Parameters |
19.3.1 | Overview |
The financial model is based on several key assumptions, including:
Production schedule, including annual brine production, pond evaporation rates, process plant production, and ramp-up schedule.
● | Plant recoveries and lithium grades. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Operating, capital, and closure costs for a 40-year operating life. |
● | Operating costs related to wellfields, evaporation ponds, process plant, waste removal, site-wide maintenance and sustaining costs, environmental costs, onsite infrastructure and service costs, and labor costs (including contractors). |
● | Product sales assumed to be Free on Board (FOB) South America. |
19.3.2 Production Rate
The Sal de Vida Project nominal capacity of annual lithium carbonate is estimated to be 15,000t/year as described in the Section 1.13.
The Table 19-1 summarizes the production quantities, grades, overall recovery, average sale prices, revenues, investments, operating costs, royalties, taxes, depreciation/amortization, and free cash flows on an annual basis with LOM totals, among other things.

Note: The overall recovery is calculated considering the total lithium units produced relative to the total lithium units pumped out of the wells. The calculated annual recovery is affected by the pond inventory and production ramp-up, causing temporary fluctuations. The total recovery (evaporation ponds and process plant) is estimated at 70% and a brine production plan has been developed for both Stage 1 and Stage 2 using this assumption. However, the eastern wellfield associated with Stage 1 does contribute additional brine volumes for Stage 2 production and for the purposes of financial modelling of Stage 1, on a stand-alone basis, an artificially lower recovery is used to maintain the lithium units required to support Stage 1 annual production.
8 Reclamation and closure costs are calculated at a Present Value of US$ 29 M and is not disclosed as a cashflow.

19.5 Indicative Economics and Sensitivity Analysis
To assess the robustness of the project’s financial results, a sensitivity analysis was conducted in a range of +/- 25% on the key variables that impact the SDV after-tax net present value (NPV). The sensitivity analysis explores the potential effects of changes in relevant variables, such as:
● | Revenue variables: |
○ | Lithium carbonate prices. |
○ Production levels.
● | Cost variables: |
○ | Capital expenditure (CAPEX). |
○ | Operating expenses (OPEX). |
The results of the analysis are summarized in Table 19-2 and Figure 19-1.

SEC Technical Report Summary
19.6 Sal de Vida Sensitivity Analysis
The sensitivity analysis examined the impact of variations in commodity prices, production levels, capital costs, and operating costs on the project’s NPV at a discount rate of 10%. The aim is to illustrate how changes in these crucial variables affect the project’s financial viability.
The following Table 19-3 and Figure 19-1 provide the insights into the NPV@10% associated with the fluctuations in the key variables.
From the analysis, the commodity price has the most significant impact on the Sal de Vida Project’s NPV, followed by production levels, OPEX, and CAPEX. Price emerges as the most influential factor with a mere 10% variation in price results in an 18% impact on the NPV. Even under adverse market conditions, such as unfavorable price levels, increased costs, and investment challenges, Sal de Vida remains economically viable.
The sensitivity analysis focused on individual variable changes, and the combined effects of multiple variable variations were not explicitly modeled in this analysis.

20. ADJACENT PROPERTIES
Within the Salar de Hombre Muerto Basin, several neighboring properties are present including: Posco Argentina (Posco), Livent, Galan Lithium Ltd. (Galan), and Minera Santa Rita (Figure 20-1). The employee of Gunn Metallurgy has not verified all information contained in this section, as most of it has been summarized from public announcements and third-party websites.
Figure 20-1 – Adjacent Properties.
Posco’s lithium project (Sal de Oro) is located in the northern area of the Salar de Hombre Muerto Basin, intersecting both the Salta and Catamarca provinces of Argentina. Posco is headquarter in South Korea, and they initially developed an extraction technology for lithium in 2010. In 2018, their offices were opened in Salta and Catamarca and a pilot plant was created with a capacity of 2,500 tonnes per year of lithium. Currently, Posco is in the advanced stage of exploration, and they expect to have a commercial plant by the end of 2023 (Posco, 2023).
Livent’s Fenix Project in Hombre Muerto West is the only current commercial producer of lithium in the basin. Livent has prepared and uploaded a S-K 1300 Technical Report Summary to the SEC website (Integral, 2023) where their Mineral Resource and Reserve Estimates along with other processing and financial analyses are reported at the pre-feasibility level. On May 10, 2023, Livent and Allkem announced that a merger will occur between the two companies to create a global leader in the lithium market. As of the effective date of this report, both companies are operating separately.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Galan owns mining properties in Hombre Muerto West, to the west of Allkem’s properties, as well as in Candelas (to the south). In Hombre Muerto West, Galan announced that their project resource has increased to 6.6 Mt of LCE, with an average of 880 mg/l of lithium (Galan, 2023). In the Candelas mine concessions, Galan’s exploration and resource estimate was announced in 2019, with an estimated resource of 685 Kt of LCE and average lithium grade of 672 mg/l (Galan, 2019).
Minera Santa Rita is a boron mining company with properties in the Salar de Hombre Muerto. The principal source of their boron exploration and reserves occurs in the properties of the salar, with 60,000 tonnes exploited per year and more than 2,000,000 t of reserves (Minera Santa Rita, 2023). The utilized mining process does not typically involve groundwater extraction; thus, the mining process is different than that of the Sal de Vida Project described in this Technical Report Summary.

This section will describe the development of the Stage 2 expansions. Stage 2 is currently at the pre- feasibility study stage and will be further developed to feasibility study level.
The Stage 2 wellfield, brine distribution, evaporation ponds, waste (wells and ponds) and, process plant capital and cost accuracy is ±25% and contingency less than or equal to 15% as defined by the SK Regulations, with remaining uncertainty associated with an expected 40-year life of mine.
21.1.1 | Stage 2 Modular Expansion |
The Sal de Vida lithium carbonate plants were designed to produce 15,000 tpa of lithium carbonate in Stage 1, with Stage 2 enabling the production of an additional 30,000 tpa through two 15,000 tpa modules. The modular plant design was based on average brine supplies of 26 m3/hr for Stage 1 and an additional 52 m3/hr for stage 2 respectively. The design includes an average lithium concentration of 21 g/l in the softening feed. Plants will operate continuously with a design availability of 91%.
21.1.2 | Stage 2 Scope |
Stage 2 will consist of further expansion of operations as established in Stage 1. All Stage 2 facilities will be located within the Stage 1 Project tenements in the southern sector of the Salar del Hombre Muerto. The wellfield will be located directly above the western sub-basin of the Salar del Hombre Muerto over the salt pan. The brine distribution will traverse the salar southeast towards the evaporation ponds on the alluvial field. The production plant for Stage 2 will be sited adjacent to the production plant for Stage 1. The waste disposal areas will surround the evaporation ponds.
The integrated expansion for Stage 2 was considered during the initial layout of the project as represented in Figure 21-1.
21.1.2.1 Increased Well Fields and Ponds
Brine production wells, referred to for the Stage 2 development as the Southwest Wellfield, will be located over the west sub-basin of the Salar del Hombre Muerto. Sixteen wells will be used for Stage 2, of which fourteen wells will be operational during the maximum brine pumping season,and two will be on stand-by. All wells will be connected through pipelines to one of two booster stations that will be situated in a central position to the wells.

Given that the Project will be developed in stages and much of the facilities and infrastructure of Stage 2 will be an extension of Stage 1, the following sub-sections will make reference to all stages of the Project unless stated otherwise.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
21.1.3.2 Baseline studies
The physical, biological, and social baseline data for the Project has been collected over the wider area of the Salar de Hombre Muerto since 2011 (ERM, 2011). Specific baseline field campaigns and environmental impact studies will need to be performed as part of the environmental permitting for Stage 2 of the Project. The Stage 2 baseline field campaigns have not commenced as yet.
21.1.3.3 Environmental impact assessment
The Environmental Impact Declaration (DIA) approved in December 2021 was for Stage 1 only and includes the brine distribution system, 320 ha of evaporation ponds, the latest flowsheet and Li2CO3 Plant, and onsite infrastructure for Stage 1 of the Project. The Stage 2 will require an amendment to the Stage 1 DIA with separate investigations related to the Stage 2 affected areas. The Stage 2 DIA application has not commenced as yet. Further study and basic engineering as required to further define the technical and economic development of Stage 2.
21.1.3.4 Water Permits
The Sal de Vida Project will require 100-120 m3/hr of raw water for the operation of Stage 1 and 2.
The granted groundwater permit was obtained on 15 May 2020, by Provincial Decree 770/20, for well SVWF12_19 with a flow of 130 m3/hr and well SVFW12_20 only for monitoring, for a term of two years (renewable), as stipulated in Article 7° of the Water Law of the Province of Catamarca, N° 2577/73.
The water permits that will be required to take account of the increased water demand to construct and operate Stage 2 of the Project have not yet been applied for.
It is estimated that required engineering, studies and permitting application processing will require approximately 18 months based on timelines experienced with Stage 1.
21.1.4 Stage 2 Capex & Opex
The capital cost estimate for Stage 2 of the Sal de Vida Project was prepared by Allkem based on previously completed studies by Worley Chile S.A. and Worley Argentina S.A. (Collectively, Worley) in collaboration with Allkem. Allkem supplemented previous study estimates with actual construction cost data obtained from the ongoing Sal de Vida Stage 1 construction.

SEC Technical Report Summary
21.1.4.1 Estimate Accuracy
The estimate is a Class 4 following AACCE International Recommended Practice No. 18R-97. Rev February 2, 2005, with an expected accuracy of +30% / - 20%. The costs are based on Q2 2023 pricing.
21.1.4.2 Basis of estimate
Capital Cost Estimation of Stage 2 was based on Sal de Vida Stage 1 AACE class 2 estimation development for Stage 1 currently in execution. The modularized nature of the project expansion allows for direct cost comparisons from Stage 1 for Stage 2, supplemented by escalation estimation and appropriate contingency. Where equipment sizing changed, established factorization techniques were applied.
21.1.4.3 Exchange rates
Exchange rates were applied similarly to Stage 1, as described in Section 19, for consistency.

21.1.4.0 Opex Summary
The operating cost estimate (Opex) for Stage 2 of the Sal de Vida Project was prepared by Allkem’s team based on Olaroz Stage 1 experience and progress on the Sal de Vida Stage 1 development. The Opex excludes indirect costs such as distributed corporate head office costs for corporate management and administration, marketing and sales, exploration, project and technical developments, and other centralized corporate services.
The Direct Materials & Consumables are proportional to the scale up in production. This assumption considers that the scale up in the purchasing volume of Materials & Consumables (e.g., reagents, fuel, etc.) does not imply a reduction in cost from economies of scale.
The only synergies stipulated are those related to labor and overheads such as Catamarca office and personnel, and its associated costs. The Opex estimate is based on current operational pricing as described in Chapter 18 of the report. Subject to the exceptions and exclusions set forth in this pre- feasibility study.
The summary breakdown is presented in Table 21-4.

21.1.5 Stage 2 Economics
Financial modelling was completed on a 100% Project basis, using the discounted cash flow (DCF) method of analysis to assess Sal de Vida’s estimated economics and evaluate the sensitivity of key input parameters on the Project expected returns.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
21.1.5.1 Basis of Analysis
For the economic analysis, the Discounted Cash Flow (DCF) method was adopted to estimate the project’s return based on expected future revenues, costs, and investments. DCF involves discounting all future cash flows to their present value using a discount rate determined by the company. This approach facilitates critical business decisions, such as Merger & Acquisition (M&A) activities, growth project investments, optimizing investment portfolios, and ensuring efficient capital allocation for the company.
Key points about the Discounted Cash Flow method:
● | The discount rate is based on the weighted average cost of capital (WACC), incorporating the rate of return expected by shareholders. |
● | All capital expenditures incurred up to June 30th, 2023, for the Sal de Vida Project were considered as sunk costs and excluded them from the present value calculations. |
The DCF approach involves estimating net annual free cash flows by forecasting yearly revenues and deducting yearly cash outflows, including operating costs (production and G&A costs), initial and sustaining capital costs, taxes, and royalties. These net cash flows are then discounted back to the valuation date using a real, after-tax discount rate of 10%, reflecting Allkem’s estimated cost of capital. The model assumes that all cash flows occur on December 31st, aligning with Allkem’s Fiscal Year.
The DCF model is constructed on a real basis without escalation or inflation of any inputs or variables. The primary outputs of the analysis, on a 100% Project basis, include:
● | NPV at a discount rate of 10%. |
● | Internal rate of return (IRR), when applicable. |
● | Payback period, when applicable. |
21.1.5.2 Assumptions
The financial evaluation is dependent on key input parameters and assumptions:
1. | Production schedule, including annual brine production, pond evaporation rates, process plant production, and ramp-up schedule. The Sal de Vida Project Stage 2 nominal capacity of annual lithium carbonate is estimated to be 30,000t/year. |
2. | Plant recoveries and lithium grades. |
3. | Operating, capital, and closure costs for a 37-years operating life. |
4. | Operating costs related to wellfields, evaporation ponds, process plant, waste removal, site-wide maintenance and sustaining costs, environmental costs, onsite infrastructure and service costs, and labor costs (including contractors). |

Note: The overall recovery is calculated considering the total lithium units produced relative to the total lithium units pumped out of the wells. The calculate overall recovery is affected by the pond inventory and production ramp-up, causing temporary fluctuations. The total recovery (evaporation ponds and process plant) is estimated at 70% and a brine production plan has been developed for both Stage 1 and Stage 2 using this assumption. However, the eastern wellfield associated with Stage 1 does contribute additional brine volumes for Stage 2 production and for the purposes of financial modelling of Stage 1, on a stand-alone basis, an artificially lower recovery is used to maintain the lithium units required to support Stage 1 annual production.
9 Reclamation and closure costs are calculated at a Present Value of US$ 88 M and is not disclosed as a cashflow.

21.1.5.5 Stage 2 Risk Assessments
A Risk Assessment process was conducted in 2021 (Spark, 2021) which identify a broad spectrum of hazards that provides a reasonable representation of the current risk profile for the project. As can be seen in Figure 21-4 the overall risk profile is currently driven by Project Delivery, and Financial/ Operational Performance10 issues, which is to be expected of this project at the Pre-feasibility stage.
10 The operational performance risk effectively results in a financial impact on Allkem as if the delivered operation is not able to make its performance targets (through-put, sales value, ramp-up etc.) this directly impacts on the cashflow and hence NPV of the project.

SEC Technical Report Summary
Figure 21-4 – Qualitative Grouping of Project Risk (Risk Consultant, 2021).
While this profile is anticipated to change over the project duration (as the nature of the risk understanding and effectiveness of the control regime changes) currently the major risk to the project is dominated by the project Deliver and Financial/ Operational Performance. This is consistent with the project management team’s expectations for a pre-feasibility study stage given the industry’s history with delivery of medium-sized project and the inherent uncertainty regarding how a number of key risks in these areas are to be managed.
While the current risk profile has a significant degree of uncertainty within it, the predominant issues seen as potential threats to project viability are as detailed in Table 21-7.
Table 21-7 – Stage 2 Risks to the Project Viability.
Risk Type | Stage 2 Risk Description |
HSE | Project as delivered (execution and into operations) fails to meet Allkem Health & Safety, Environmental or CSR expectations. |
Community | Loss of Community Support for project. |
Financial | Project CAPEX blow-out (Productivity, Incomplete engineering, Poor estimation, Project delays, Poor project controls, Changing market conditions, etc.) |
Financial | Plant unable to achieve Ramp-up to full production rates to plan. |
Financial | As built plant fails to achieve the lithium carbonate production expectation (throughput/ utilization/ recovery/ product quality). |
Financial | Changing in Argentinian financial/ regulatory framework (taxation, new legislation, import/ exports, inflation). |
Project Delivery | Increased complexity of the design (battery grade, automation, late change to the design) impacting the schedule or budget. |
Project Delivery | Delays to achieving the planned project schedule. |
Project Delivery | Ability for the EPCM to deliver the full spectrum of Allkem expectations (Schedule, Cost, Quality, remote operations). |
Regulatory | Ability to meet all required condition (70:30, Environmental, etc.) |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
The existing controls and those that will be implemented during the implementation/ operations phases, are broadly defined in the relevant risk register, and will be enhanced as the register is revisited through the project delivery and into operations. These controls are predicted to be appropriate for the further reduction of the risk, however, ongoing effort will be required to ensure the delivery of all required controls to achieve acceptable (and well understood) levels of risk within the project.
While it is clear there is still considerable risk assessment work yet to be undertaken through the development of the Sal de Vida Project, there are no current risk issues that have been identified that are considered insurmountable or that will prevent the project from being delivered, although those listed in Table 21-7 will require specific focus and comprehensive follow-up.
21.1.6 Stage 2 Conclusion
The planned Sal de Vida Stage 2 expansion has been studied at a pre-feasibility study level. The process pond infrastructure, process plant design and support service infrastructure are deemed of suitable design and sufficiently quantified to support the level of study. The accuracy of cost information gained from ongoing Stage 1 execution is deemed sufficiently accurate for the level of study. Within the constraints described in this chapter, it is the opinion of the employee of Gunn Metallurgy that the Stage 2 expansion will support economically viable extraction of the mentioned saleable lithium products.
21.1.7 Stage 2 Recommendations
The Sal de Vida Stage 2 expansion must progress with further studies toward improving financial accuracy, reducing schedule and overall risk. A detailed feasibility study is recommended.
After completing any required value engineering, finalizing technology tradeoffs and selections, and advancing engineering design, the permitting process should commence in parallel with further engineering design. Progression of the Stage 1 execution must be monitored, and lessons learned incorporated into the Stage 2 project. Ongoing risk management and reviews are recommended to ensure currency of risk management activities. Social engagement processes and programs can be amended as needed to include for the future Stage 2 expansion.

21.2 | Risks and Opportunities |
21.2.1 | Risks |
A Project risk workshop was held in February 2020 and was subsequently updated in a risk assessment process was conducted on March 21, 2021. This identified a broad spectrum of hazards which provides a reasonable representation of the current Project risk profile, with a focus on the initial stage of the Project. The overall risk profile is currently driven by Project delivery, and financial/ operational performance issues, which is to be expected of a brine project at the feasibility stage. This is consistent with the Project management team’s expectations for a feasibility-stage study, given the industry’s history with medium- sized project delivery, and the inherent uncertainty as to how a number of key risks in these areas can to be managed.
The Sal de Vida Project had ~70 risks identified for areas of focus in the Project risk register. The key risks to Project viability can be summarized as:
● | Allkem activities fail to meet health, safety, environmental, community (HSEC) or CSR expectations. |
● | Loss of community support for the Project. |
● | Project capital cost increases significantly (e.g., productivity, incomplete engineering, poor estimation, Project delays, poor Project controls, changing market conditions). |
● | Plant unable to achieve name plate production within expected timeframes. |
● | Plant fails to achieve the production metrics (e.g., throughput, utilization, recovery, product quality). |
● | Changes to the Argentinian financial/regulatory framework (e.g., taxation, new legislation, import/ exports, inflation). |
● | Increased complexity of the design (BG, automation, late changes to the design) impacting the rate of engineering, procurement of long leads, commissioning etc. |
● | Performance of selected contractors (schedule, cost, quality, remote operations). |
● | COVID-19 or similar impacting the Project (cost, schedule, outbreak on site). |
● | Ability to meet all required stakeholder conditions (e.g., local employment, environmental). |
The existing risk controls and those that will be implemented during the implementation/ operations phases are broadly defined in the relevant risk register and will be enhanced as the register is revisited throughout the Project delivery phase and into the operational phase. These controls are predicted to be appropriate for further risk reduction; however, ongoing effort will be required to ensure the delivery of all required controls to achieve acceptable risk levels within the Project, and that these risks are well-understood. This risk/reward evaluation will need to be reviewed at each key Project stage.

21.2.2 Opportunities
Strategically, the two staged approach allows prudent de-risking of the development, by adopting experience from Stage 1 into later stages. It is expected that the subsequent stage will not commit significant funds until the previous stage production is proven. Additionally, it is expected that Stage 2 delivery costs from continuity of people, systems and processes, engineering efficiencies and targeted allocation of contingency may provide upside. The PFS level does not accommodate these synergies, but they are expected as engineering advances.
The estimated Brine Resources and Brine Reserves summarized in this Report may have upside potential for tonnage increases, based on results from the ongoing production well drilling, and aquifer testing of the recently constructed Eastern wellfield production wells.
Currently, the area that includes the East Wellfield is designated as Indicated. Even though the conceptual understanding of this area is very good, this designation is because aquifer tests have previously been conducted at only two wells in the area. The 2020 – 2021 production well program for this area will increase aquifer understanding and could result in Brine Resource confidence category upgrades.
The Southwest Wellfield is currently considered to be very conservatively categorized as Inferred because only information from failed borehole SVH10_05 exists for that area. Borehole SVH10_05 could not be completed because of flowing brine conditions in a highly transmissive, and nearly uncemented sand and gravel unit. Good quality brine was confirmed in the area, but measurements equivalent to other boreholes used to characterize the Brine Resource were not possible. With additional drilling and testing in the area, there is potential to upgrade the Brine Resource confidence category.
Two of the already-drilled production wells have reached bedrock at about 220 meters below land surface (m bls), and one has been drilled to over 300 m bls without reaching bedrock. Previous exploration drilling allowed for a maximum depth of the Brine Resource to about 170 m bls. These deeper drill holes have upside potential to extend the limit of the Brine Resource estimates at depth.
The Brine Resources are reported above a 300 mg/l Li cut-off. Many of the brine players in the industry use a 200 mg/l Li cut-off. Should Allkem elect to lower the cut-off, there is potential for additional lithium carbonate content to be estimated as part of the Brine Resources. Changing the cut-off grade will have no impact on the Brine Reserve because all the production wells associated with the Brine Reserve are being designed to avoid capturing this lower lithium grade brackish water. If the Project continues past the current projected 40-year mine life, lower- grade brine and brackish water have potential to be economic in the future.

22. | INTERPRETATION AND CONCLUSIONS |
This section contains forward-looking information related to the Sal de Vida Project. The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions set forth in this Technical Report Summary related to exploration, resource, reserve, processing, or financial analyses.
The QPs believe that this Technical Report Summary was prepared in accordance with the SEC’s S-K 1300 requirements. The QPs note the following interpretations and conclusions in their respective areas of expertise, based on the review of data available for this Report.
22.1 Geology and Mineralization
The Sal de Vida deposit is considered to be typical of a brine system with an evaporite core dominated by halite in the northern and western areas, as well as interbedded clastic sediments which are predominant in the southern and eastern portions of the mine concessions. The most notable source of fresh water to Salar del Hombre Muerto is the Río de los Patos drainage that enters the basin from the southeast.
Sal de Vida’s brine chemistry has a high lithium grade, low levels of magnesium, calcium and boron impurities and readily upgrades to battery grade lithium carbonate. The knowledge of the hydrogeological system is sufficient to support the Mineral Resource and Reserve estimates.
22.2 Exploration, Drilling, and Analytical Data
Exploration activities to date have identified the Sal de Vida brines, and has used exploration methodology conventional to brine exploration, such as geophysics and surface sampling, in addition to the drilling programs.
Drilling was conducted in several phases including small diameter shallow wells, brine exploration diamond drillhole (DDH) wells, pilot brine production wells, freshwater wells, and reverse circulation (RC) drill holes. The phases were broken out into Phase 1 to 6, with Phase 1 commencing in 2009, and Phase 6 in 2021 as part of the East wellfield development. Drill data are acceptable to support the Mineral Resource and Reserve estimates.
Short-term pumping tests were completed as part of all drill program phases to measure aquifer transmissivity, obtain a representative brine sample for the well, and provide design data for future higher-capacity production wells.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Analyses for porosity and brine chemistry were performed at accredited laboratories independent of Allkem. Analytical quality was monitored through the use of randomly inserted quality control samples, including SRMs, blanks and duplicates, as well as check assays at independent laboratories. The drainable porosity and chemistry data to support the Brine Resource estimate were verified. These verifications confirmed that the analytical results delivered by the participating laboratories and the digital exploration data were sufficiently reliable for Brine Resource estimation purposes.
Sample collection, preparation, analysis, and security for the drill programs are in line with industry- standard methods for brine deposits. Drill programs included QA/QC measures. QA/QC program results do not indicate any problems with the analytical programs. The employees of Montgomery & Associates are of the opinion that the quality of the analytical data is sufficiently reliable to support the Mineral Resource and Reserve estimates.
The conceptual understanding of the hydrogeological system of Salar del Hombre Muerto is good, and the observed drilling and testing results are consistent with anticipated stratigraphic and hydrogeological conditions associated with mature, closed-basin, high altitude salar systems. One of the most important features of this hydrogeological system is the general consistency of the lithium and potassium grades measured throughout the entire salar and the high value of lithium grade. The majority of the salar contains high-density brine with an average lithium grade over 700 mg/l. The identified aquifer units in the basin are shown to be aerially extensive with a demonstrated ability to pump brine.
22.3 Mineral Resources
To estimate the Mineral Resource, utilized parameters correspond to drainable porosity and brine concentration. The polygon method was used, a commonly applied method for lithium brine resource estimates, where the mine properties were first sectioned into polygons based on the location of exploration drilling. Each polygon block contained one core drill exploration hole that was analyzed for both depth-specific brine chemistry and drainable porosity, and the base of each polygon corresponds to the total well depth. Boundaries between polygon blocks were generally equidistant from the core drill holes. The total area of polygon blocks used for resource estimates is about 160.9 square kilometers (km2). Within each polygon shown on the surface, the subsurface lithological column was separated into lithologic units and discrete intervals with data, where a specific thickness with a value for drainable porosity and average lithium content was assigned based on laboratory analyses of samples collected during exploration drilling. The estimated resource for each polygon was the sum of the products of saturated lithologic unit thickness, polygon area, drainable porosity, and lithium content. The resource estimated for each polygon was independent of adjacent polygons.
The Mineral Resource, exclusive of Mineral Reserves, corresponds to 3.07 Mt of LCE for the Measured category and 0.96 Mt of LCE for the Indicated category, with a total Measured and Indicated Resource (exclusive of Mineral Reserves) of 4.03 Mt of LCE. Mineral Resources inclusive of Mineral Reserves are also reported. To classify a polygon as Measured or Indicated, the following factors were considered: (i) level of understanding and reliability of the basin stratigraphy, (ii) level of understanding of the local hydrogeologic characteristics of the aquifer system, and (iii) density of drilling and testing in the salar and general uniformity of results within an area. A lithium cut-off grade of 300 mg/l was conservatively utilized based on a breakeven cut-off grade for a projected lithium carbonate equivalent price of US$20,000 per tonne over the entirety of the LOM and a grade tonnage curve (Figure 11-2). Intervals of each polygon with lithium content less than cut-off grade were not included in the resource estimate, demonstrating a reasonable basis for the prospects of economic extraction for Mineral Resources.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Factors that may affect the Brine Resource estimate include: locations of aquifer boundaries; lateral continuity of key aquifer zones; presence of fresh and brackish water which have the potential to dilute the brine in the wellfield area; the uniformity of aquifer parameters within specific aquifer units; commodity price assumptions; changes to hydrogeological, metallurgical recovery, and extraction assumptions; density assignments; input factors used to assess reasonable prospects for eventual economic extraction; and assumptions as to social, permitting and environmental conditions. To the extent known by the employees of Montgomery & Associates, there are no known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors that could affect the Mineral Resource estimate which are not discussed in this Report.
22.4 Mineral Reserves
The Mineral Reserve was estimated using a calibrated numerical model which simulates groundwater flow and solute transport. The method considers the modifying factors for converting Mineral Resources to Mineral Reserves in brine deposits, including allowable well field pumping, dilution of brine during production, process recovery factors, among others.
The 3D numerical model was constructed using the Groundwater Vistas Version 7 interface and Modflow USG-Transport was utilized to simulate variable-density flow and transport. Prior to the simulation of future brine production, the numerical model was calibrated to verify assigned model parameters such as hydraulic conductivity and specific storage. The numerical groundwater model was initially calibrated to average, steady-state conditions using the available average on-site field measurements of water levels in observation wells. A transient model calibration to two long-term pumping tests in the East and Southwest Wellfields was conducted to better represent the aquifer’s response to pumping. Furthermore, a verification period was analyzed with regard to extracted concentrations in early 2023.
For the numerical model projections, total lithium to be extracted from the proposed wellfields was calculated for a total period of 40 years considering the two stages of the Project and considering that the East Wellfield will be pumping for 40 years and that the Stage 2 Expansion wells will be pumping for 38 years (at the start of year 3 of the LOM). The projected wellfields were designed to produce a reliable quantity of brine at an average annual rate of approximately 315 L/s in the case of the East Wellfield and 191 L/s in the case of the Southwest Wellfield.
From the point of reference of brine pumped to the evaporation ponds, the estimated Proven Reserve corresponds to 0.445 Mt of LCE while the estimated Probable Reserve is 2.041 Mt of LCE, with a total Proven and Probable Reserve of 2.486 Mt of LCE. The Mineral Reserve was classified according to industry standards for brine projects, as well as the confidence of the numerical model predictions and potential factors that could affect the estimation.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Production wells were placed in Measured Resource zones. The employees of Montgomery & Associates believe that the Proven and Probable Mineral Reserves were adequately categorized, as described below:
● | Proven Reserves were specified for the first 7 years of operation (years 1-7 in the East Wellfield (Stage 1) and years 3-9 for the Stage 2 Expansion given that short-term results have higher confidence due to the current model calibration and also the initial portion of the projected LOM has higher confidence due to less expected short-term changes in extraction, water balance components, and hydraulic parameters. |
● | Probable Reserves were conservatively assigned after 6 years of operation (years 8-40 in the East Wellfield and years 10-40 for the Stage 2 wells because the numerical model will be recalibrated and improved in the future due to potential changes in neighboring extraction, water balance components, and hydraulic parameters. |
During the evaporation and concentration process of the brine, there will be anticipated losses of lithium. Based on the Chapter 10 breakdown of recoveries and consideration of deleterious element concentrations, the amount of recoverable lithium from the ponds and plant is calculated to be 70% of the total brine supplied to the ponds. This applies for the current processing method which may be subject to improvements at a later date.
Factors that may affect the Brine Reserve estimate include:
● | Assumptions regarding aquifer parameters and total dissolved solids used in the groundwater flow model for areas where empirical data do not exist. |
● | Estimated vertical hydraulic conductivity values which partially control the amount of anticipated future dilution in areas where fresh water overlies brine. |
Regardless of these sources of uncertainty, each phase of the Project was conducted in a logical manner, and results were supportable using standard analytical methodologies. In addition, calibration of the numerical model against long-term pumping tests provides solid support for the conceptual hydrogeologic model developed for the Project. Thus, there is a reasonably high-level confidence in the ability of the aquifer system to yield the quantities and grade of brine estimated as Proven and Probable Mineral Reserves. To the extent known by the employees of Montgomery & Associates, there are no known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors that could affect the Mineral Reserve estimate which are not discussed in this Report.

SEC Technical Report Summary
23. | RECOMMENDATIONS |
23.1 | Exploration |
Exploration should be conducted to better identify and potentially demonstrate additional extractable brine in other parts of the basin. Favorable exploration results represent Project upside potential. The following additional investigations are recommended:
● | Geophysical surveys: perform additional gravity, magnetic, and resistivity surveys over the east, south and west sub-basins to supplement the existing surveys. |
● | Core drilling: additional wells in the southwest and eastern portions of the mine concessions that are deeper than 300 m. |
● | Downhole sampling of any additional wells to obtain brine chemistry and drainable porosity results. |
● | Additional 30-day pumping tests to identify potential for new wellfields. |
Quality assurance and quality control (QA/QC) measures should be continued for all collected brine samples including the use of blanks, duplicates, standards, and secondary (external) laboratories to increase confidence in the obtained data. 10% to 20% of the collected samples should be analyzed for QA/QC purposes, and a round-robin analysis of brine samples is recommended. The determination of drainable porosity should be confirmed with two independent methodologies including the analysis of core samples and indirect measurements (e.g. borehole magnetic resonance), among others.
This program is estimated at US$3 M.
23.2 | Resource Estimate |
23.2.1 | Resource block model |
It is recommended that a resource block model be created instead of the polygon method to estimate the lithium brine resource. The recommended block model will incorporate the same input parameters as the polygon method (lithium concentration and drainable porosity) in the categorized zones, however more refined block sizes and an appropriate interpolation method is believed to improve confidence in the resource estimate. Furthermore, new brine sample results from pumping and production wells should be incorporated.
This initial resource model update is estimated at US$200,000.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
23.2.2 Block model updates
Based on newly obtained field data which would include additional wells, depth specific sampling for brine and drainable porosity at greater depths, and additional pumping tests, the resource estimate should be updated. The categorization should also be reviewed based on newly obtained information.
The subsequent resource model update is estimated at US$200,000.
23.3 Reserve Estimate
23.3.1 Further collection of data
The numerical model should be updated in the short to medium term to simulate lithium in addition to total dissolved solids. The simulation of total dissolved solids is necessary to properly simulate density- driven flow due to its good correlation to water density. However, recent software advances allow for a more feasible simulation of multiple solutes; thus, it is recommended that lithium be simulated as the second solute (instead of based on the linear relationship to total dissolved solids) to improve the reserve estimate. To incorporate lithium, a 3D distribution is required for the initial conditions of the reserve simulation, and the calibration phase should be revisited to confirm the simulated lithium grades. During this update, the grid refinement should also be adjusted based on the most recent wellfields.
This initial reserve model update is estimated at US$200,000.
23.3.2 Updating of models
A review of the numerical model should be completed when information from the Recommendations Phase 1 work is available. Results of the gravity and magnetic surveys should be used to reinterpret the structural model with the inclusion of all existing core holes. A sensitivity analysis should be completed on the updated steady-state and transient calibration models as well as the predictive model based on potential changes in the anisotropy of hydraulic conductivity, and the extension of the deeper, more permeable units, along with other important model parameters such as effective porosity and dispersivity.
Modeling other elements of interest as distinct solutes in the model could be conducted, rather than relying on the best-fit linear curves with TDS. This will allow for the improved determination of extracted concentrations of other solutes that are not well correlated to TDS (e.g., magnesium and sulphate).
The grid should be further refined in areas of the projected production wells and the deeper portions of the numerical model should be updated with improved information on the brines at depth, including the hydraulic conductivity and storage zones. Also, model calibration in the Río de los Patos sub-basin should be updated, depending on the streamflow measurement data.
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
Recommended future work includes:
● | A sensitivity analysis on the updated steady-state and transient calibration models as well as the predictive model based on potential changes in the anisotropy of hydraulic conductivity, and the extension of the deeper, more permeable units, along with other important model parameters such as effective porosity and dispersivity. |
● | A detail analysis of flow units and low conductivity clay barriers, including lateral extension over the modeled area. This will further improve decisions on future drillings locations and screened zones, understanding of the connectivity with shallower aquifers and surface, and estimate drawdown effects over time. |
● | Upon additional deeper drilling, updating the deeper portions of the numerical model with improved information including the hydraulic conductivity and storage zones. |
● | Collection of quarterly streamflow measurements along the Río de los Patos at multiple locations in order to improve its representation in the numerical model and better evaluate the gaining and losing reaches of the river. |
● | Continued monitoring of water levels and water chemistry data from wells and surface water. |
● | Further improvement of the model calibration in the Río de los Patos sub-basin if a detailed evaluation of freshwater extraction is needed. |
● | Further vertical refinement of the upper model layer to better represent evapotranspiration and changes in water density at the surface. |
● | Recalibration of the model after at least 1 year of production wellfield pumping and monitoring. |
This reserve model update is estimated at US$300,000.
23.4 | Environmental Studies |
According with the water balance report (Montgomery & Associates, 2020) liquid and solid (snowmelt) precipitation in the basin is estimated at 129 mm/a, or as a volumetric rate, at 39,780 m3/hr. Using 5 – 20% of the annual volumetric precipitation, an estimated range of precipitation recharge is likely between 1,980 – 7,920 m3/hr (Montgomery & Associates, 2020). The current best estimate for groundwater recharge at this area is considered to be 5,400 m3/hr; however, whenever the recharge estimate is used, it is recommended that a sensitivity analysis for recharge rates as low as 1,980 m3/hr, or as high as 7,920 m3/hr also be run. If these sensitivity analyses identify a risk, then a more focused investigation may be required to assess the chance of a having a recharge below or above a specific value (Montgomery & Associates, 2020). Specific factors that are recommended for investigation include:
● | Estimating runoff and shallow groundwater directions and rates from available topography. |
● | Estimating trends in precipitation, snowmelt, and evaporation in the mid-term (approximately 30 years) and long term (approximately 60 years) from IPCC approved climate models for an intermediate scenario. |
Sal de Vida Lithium Brine Project
SEC Technical Report Summary
● | Evaluating the variation of drought periods and wet periods from the climate record and from remote sensing observations of lake extents in the salar over the last 40 years. Determine whether El Niño Southern Oscillation (ENSO) effect can be observed in the record. |
● | Generating scenarios for multi-year droughts that last as long as those interpreted from the above-mentioned analysis. |
● | Modeling the effects of the water balance of dry, average, and wet scenarios, with and without effects of groundwater withdrawals derived from the groundwater model. |
● | Ecological flows should be estimated for Río de Los Patos upstream and downstream of where groundwater pumping will occur. |
● | Ecological levels should be estimated for the lakes in the salar, including Laguna Verde and Laguna Catal. |
● | Generating a synthetic climate and surface flow series based on the existing meteorological and streamflow monitoring existing to date. |
● | Model the seasonal and multi-year variations in the water balance based on the field data. |
Collection of quarterly streamflow measurements along the Río de los Patos at multiple locations should be conducted to improve its representation in the numerical model and better evaluate the gaining and losing reaches of the river.
Monitoring of water levels and water chemistry data from wells and surface water should continue to provide additional data for numerical modeling purposes.
This program is estimated at US$300,000.
23.5 | SDV Stage expansion |
The Sal de Vida Stage 2 expansion must progress with independent review of the process design and the plant engineering, and with further studies toward improving financial accuracy, reducing schedule and overall risk. A detailed feasibility study is recommended.
After completing any required value engineering, finalizing technology tradeoffs and selections, and advancing engineering design, the permitting process should commence in parallel with further engineering design. Progression of the Stage 1 execution must be monitored, and lessons learned incorporated into the Stage 2 project. Ongoing risk management and reviews are recommended to ensure currency of risk management activities. Social engagement processes and programs can be amended as needed to include for the future Stage 2 expansion.

Cauchari Lithium Brine Project
SEC Technical Report Summary
1. | Executive Summary |
1.1 | Background |
This report discloses the lithium brine mineral resource for Allkem Limited’s (Allkem’s) Cauchari Project (Cauchari or “the Project”). The Project is a planned lithium brine mining and processing facility that will produce lithium carbonate.
Initial studies of the Cauchari Mineral Resource and Reserves indicate the potential for a 25,000 tonne per annum (tpa) Lithium Carbonate Equivalent (LCE) processing facility with a life expectancy of 30 years. The Project is still in the Pre-feasibility study phase.
This report has been prepared in conformance with the requirements of the Securities and Exchange Commission (SEC) S-K Regulation (Subpart 1300) (the “SK Regulations”). This individual Technical Report is the initial report to be issued in support of Allkem’s listing on the New York Stock Exchange (NYSE).
This report updates Project Resources, cost estimates, and economics as of the Effective Date (June 30, 2023). Cost estimates and economic assessments for the 25,000 tpa processing facility are at a AACE Class 4 +30% / - 20% level with no escalation of costs in the context of long-term product pricing estimate.
Conclusion, recommendations, and forward-looking statements made by Qualified Persons “QPs” are based on reasonable assumptions and results interpretations. Forward-looking statements cannot be relied upon to guarantee Project performance or outcomes and naturally include inherent risk.
This report was amended to include additional clarifying information in October 2023 and November 2023. The basis of the report is unchanged. The changes and their location in the document are summarized in Chapter 2.1.
1.2 | Property Description and Ownership |
Cauchari (latitude 23° 29’ 13.19” South, longitude 66° 42’ 34.30” West) is located in the Puna region, 230 kilometers west of the city of San Salvador de Jujuy in Jujuy Province of northern Argentina and is at an altitude of 3,900 meters (m) above sea level. The property is to the south near paved Hwy. 52 that connects with the international border with Chile (80 km to the west) and the major mining center of Calama and the ports of Antofagasta and Mejillones in northern Chile, both major ports for the export of mineral commodities and import of mining equipment.
The climate in the Cauchari area can be described as typical of a continental, cold, high-altitude desert, with resultant scarce vegetation. The climate allows year around project operation.
The Cauchari tenements cover 28,906 ha and consist of 22 minas which were initially applied for on behalf of South American Salars (SAS). There is an agreement between the vendors of these tenements and SAS.
SAS is a joint venture company with the beneficial owners being Advantage Lithium (AAL) with a 75% interest and La Frontera with a 25% stake. La Frontera is an Argentine company 100% owned by Orocobre Ltd. Orocobre acquired all outstanding shares of AAL on February 19, 2020, and gained full (100 %) control of the Project. Orocobre merged with Galaxy Lithium to form Allkem Limited on August 21, 2021. Allkem indirectly owns 100% of the Cauchari tenements. The Project is not subject to any known environmental liabilities.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The Cauchari property is located near (approximately 20 km) Allkem’s Olaroz lithium carbonate-producing property. The Olaroz property has been extensively studied and has been producing lithium carbonate products since 2015. The Cauchari study draws inferences and approximations from the Olaroz property in terms of process design and expected performance, pond design and evaporation, and infrastructure requirements and sizing.
1.3 | Geology and Mineralization |
1.3.1 | Geology |
Based on the drilling campaigns carried out in the Salar between 2011 and 2018, six major geological units were identified and correlated from the logging of drill cuttings and undisturbed core to a general depth of over 600 m. No borehole has reached bedrock. Salar de Cauchari is a mixed-style salar, with a halite nucleus in the center of the Salar overlain with up to 50 m of fine grained (clay) sediments. The halite core is interbedded with clayey to silty and sandy layers. The Salar is surrounded by relative coarse-grained alluvial and fluvial sediments. These fans demark the perimeter of the actual Salar visible in satellite images and at depth extend towards the center of the Salar where they form the distal facies with an increase in sand and silt. At depth (between 300 m and 600 m) a deep sand unit has been intercepted in several core holes in the SE Sector of the Project area.
1.3.2 | Mineralization |
The brines from Salar de Cauchari are solutions nearly saturated in sodium chloride with an average concentration of total dissolved solids (TDS) of 290 g/l. The average density is 1.19 g/cm3. Components present in the Cauchari brine are K, Li, Mg, Ca, Cl, SO4, HCO3, and B. Table 1-1 shows a breakdown of the principal chemical constituents in the brine including maximum, average, and minimum values, based on the 546 brine samples that were collected and analyzed from the exploration boreholes during the 2011 and 2017/18 drilling programs.

1.4 | Exploration Status |
Three drilling campaigns have been carried out for the Project between 2011 and 2018. The first program in 2011 by SAS (Phase I) covered the SE Sector of the Project area, and the second and third campaigns (Phase II and III) by AAL covered both the NW and SE Sectors of the Project area. The work carried out during the three drilling campaigns can be summarized as follows:
● | Exploration drilling on a general grid basis to allow the estimation of “in-situ” brine resources. The drilling methods were selected to allow for: |
1) | The collection of continuous core to prepare “undisturbed” samples from specified depth intervals for laboratory porosity analyses and |
2) | The collection of depth-representative brine samples at specified intervals. The 2011 campaign included five (5) diamond core holes CAU01 though CAU05 and one rotary hole (CAU06). The second and third campaigns in 2017/18 included twenty (20) diamond core holes (CAU12 through CAU29). |
● | Brine sample collection during the drilling programs consisted of bailed and packer samples in the diamond holes, and packer and pumped samples in the rotary holes. A total of 1,946 brine samples (including 540 QA/QC samples) were analyzed by NorLab (Jujuy, Argentina) as the primary laboratory and by Alex Steward Assayers (Mendoza, Argentina) and the University of Antofagasta (Chile) as secondary QA/QC laboratories. Additional brine QA/QC analyses were carried out on centrifuged samples collected by the Geosystems Analysis laboratory in Tucson, AZ. |
● | HQ core was retrieved during the diamond core drilling from which some 415 primary undisturbed samples were prepared for laboratory drainable porosity and other physical parameter determinations by GeoSystems Analysis (GSA) in Tucson, AZ. Laboratory QA/QC porosity analyses (30) were undertaken by Corelabs in Houston, TX, and Daniel B Stephens & Associates laboratories (DBSA) in Albuquerque, NM. |
● | The 2017/18 campaign included five rotary holes (CAU07 though CAU11) which were drilled and completed as test production wells to carry out pumping tests and additional selective brine sampling. Six nested monitoring wells were installed adjacent to CAU07 and CAU11 for use during the long-term pumping tests as part of the Phase III program. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | Initial short-term (48 hour) pumping tests were carried out on CAU07 through CAU11 during 2017. Long-term pumping tests (30 days) with subsequent recovery were carried out on CAU07 and CAU11. |
● | A number of geophysical surveys have been carried out since 2011 in the Project area to further define basin geometry, and continuity of lithological units, and to define the brine / freshwater interface along the perimeter of the Salar. These geophysical surveys included gravity, TEM, VES, and AMT methods. |
1.5 | Development and Operations |
1.5.1 | Mineral Processing and Recovery Methods |
Specific brine evaporation and metallurgical recovery test work at the Cauchari site has not progressed as of the Effective Date. The Cauchari brine has been sampled and tested with results indicating similar characteristics to the Allkem Olaroz site brine. This is expected due to the proximity (20 km) and interconnectedness of the Olaroz and Cauchari salars.
The brine variance on Mg/Li and Li/ SO4 ratios for both Cauchari and Olaroz brines are low enough to state that Cauchari brine could be processed using similar processing technology to that applied in the Olaroz production facility. The Olaroz process design has been successfully proven to produce lithium carbonate since 2015.
1.5.2 | Process Facility Design |
The QPs are familiar with both the Cauchari and Olaroz basins and has visited both sites, including the Olaroz processing facilities during operation. It is the QPs opinion that the Olaroz process as described in section 1.5.2.1 Olaroz Project design approximation is a suitable approximation and has been utilized for the Cauchari process.
Cauchari Lithium Brine Project
SEC Technical Report Summary
1.5.2.1 | Olaroz Project design approximation |
The Olaroz brine chemical behavior under evaporation was studied extensively in pilot scale ponds, along with the key plant process steps such as lime addition, impurity removal and carbonation. The purification process via conversion to lithium bicarbonate was pilot-tested at the University of Jujuy. Testing was conducted between 2009 and 2011.
The Olaroz project design is a conventional pond evaporation operation. After concentration
brine is processed in the plant to produce lithium carbonate product.
The lithium carbonate process used by Allkem in their Olaroz plant is well proven and has been operating for several years. This process can be applied directly to the Cauchari project, given the similarity between the Cauchari and Olaroz brines.
1.6 | Mineral Resource Estimate |
1.6.1 | Inputs and Estimation Methodology |
The Cauchari resource model domain covers an area of 117.7 km2 and is constrained by the following factors:
● | The top of the model coincides with the brine level in the salar as measured in several monitoring wells and further interpreted by TEM and SEV geophysical profiles. |
● | The lateral boundaries of the model domain are limited to the area of the Cauchari tenements where they flank the neighboring LAC concessions and by the brine / freshwater interface along the eastern and western limits of the salar as interpreted from boreholes information and TEM and SEV profiles. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | The bottom of the model coincides with a surface created from the bottom of the boreholes. Locally, a deeper resource volume has been defined in the Lower Sand as defined by boreholes CAU11R, CAU12DA, CAU13DA, and CAU19D. |
The resource model has been divided into three domains to account for the different data availability, geological knowledge, and sample support. The domains are described as follows:
● | Transition Domain: Accounts for five percent of the total resources and is defined as the volume in the upper part of the salar that includes fresher water and transition into pure brine. The lithium concentrations in the transition zone increase with depth. The number of brine samples in the transition domain is low. |
● | Main Domain: Accounts for 83% of the total resources and has normal and reliable sample data obtained during the drilling. A kriging approach was selected for this domain due to the number of samples available. |
● | Secondary Data Domain: Accounts for 12% of the total resources and its lithium content was defined mostly by brine chemistry analysis on samples derived during pumping tests on CAU8, CAU9, CAU10, and CAU11. An inverse distance approach was selected because of the amount of information available. |
The resource estimate was prepared in accordance with the guidelines of S-K1300 and uses best practice methods specific to brine resources, including reliance on core drilling and sampling methods that yield depth-specific chemistry and drainable porosity measurements.
The Stanford Geostatistical Modeling Software (SGeMS) was used for the Cauchari brine resource estimation. SgeMS has been used in the past for the estimation of brine resources in other areas of the Central Andes. Geostatistics is a branch of statistics specifically developed to estimate ore grades for mining operations from spatiotemporal datasets. Geostatistics goes far beyond simple interpolation methods such as nearest neighbor or inverse distance as it accounts for the spatial correlation and continuity of geological properties typically observed in the field. Based on this, the following steps were carried out to estimate the lithium and potassium resources.
● | The block model geometry was adapted to represent the geological model with an appropriate block size (x=100 m, y=100 m, z=1 m). |
● | Generation of histograms, probability plots and box plots were conducted for the Exploratory Data Analysis (EDA) for lithium and potassium. |
● | Calculation of the experimental variograms with their respective variogram models for lithium and potassium in three orthogonal directions. |
● | Definition of the random function model and selection of the kriging method. |
● | Interpolation of lithium and potassium for each block in mg/l using ordinary kriging with the defined variogram models. |
● | Calculation of total resources using the de-clustered porosity average value for each geological unit, based on the boreholes data. Each geological unit will represent its particular porosity value. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
1.6.1.1 | Cut-off concentration |
A lithium cut-off grade of 300 mg/l was utilized based on a breakeven cut-off grade for a projected lithium carbonate equivalent price of US$ 20,000 per tonne over the entirety of the LOM and a grade-tonnage curve. Considering the economic value of the brine against production costs, the applied cut-off grade for the resource estimate (300 mg/l) is believed to be conservative in terms of the overall estimated resource. Domains in the block model with grades below the 300 mg/l cut-off grade were not considered in the resource estimate; thus, with these assumptions, a reasonable basis has been established for the prospects of eventual economic extraction.
Furthermore, the assigned 300 mg/L cut-off grade is consistent with other lithium brine projects of the same study level, which use a similar processing method. The resource is relatively homogeneous in grade (as shown in the grade-tonnage curve of Figure 11-17), and the average concentration is well above the cost of production, with brine concentrated in low-cost solar evaporation ponds.
The price estimate for Lithium Carbonate is based on information provided by industry consultants Wood Mackenzie, based on their extensive studies of the lithium market. Actual prices are negotiated by Allkem with customers, generally as contracts related to market prices.
Mr. F. Reidel AIPG (the QP) understands the lithium market will likely have a shortfall of supply in the coming few years, which will support higher than inflation-adjusted historical prices. Based on 2022 and 2023 pricing to date, the Wood Mackenzie analysis is considered a reasonable basis for pricing through to 2025. By this time, a new technical report will likely be completed, outlining details for the feasibility study.
1.6.2 | Mineral Resource Classification |
This sub-section contains forward-looking information related to Mineral Resource estimates for the Cauchari Project. The material factors that could cause actual results to differ from the estimates or conclusions include any significant differences from one or more of the material aspects or assumptions set forth in this sub-section including geological and brine grade interpretations, as well as controls and assumptions related to establishing reasonable prospects for economic extraction.
The essential elements of a brine resource determination for a salar are:
● | Definition of the aquifer geometry. |
● | Determination of the drainable porosity or specific yield (Sy). |
● | Determination of the concentration of the elements of interest. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
Resources may be defined as the product of the first three parameters. Aquifer geometry is a function of both the shape of the aquifer, the internal structure, and the boundary conditions (brine / freshwater interface). Aquifer geometry and boundary conditions can be established by drilling and geophysical methods. Hydrogeological analyses are required to establish catchment characteristics such as surface and groundwater inflows, evaporation rates, water chemistry, and other factors potentially affecting the brine reservoir volume and composition in-situ. Drilling is required to obtain samples to estimate the salar lithology, specific yield, and grade variations both laterally and vertically.
It is the opinion of the QPs that the salar geometry, brine chemistry composition, and the specific yield of the salar sediments have been adequately defined to support the Measured, Indicated, and Inferred Resource estimate described in Table 1-2 and Table 1-3.

Proven Mineral Reserves (from the point of reference of brine pumped to the evaporation ponds) were subtracted from Measured Mineral Resources, and Probable Mineral Reserves (from the point of reference of brine pumped to the evaporation ponds) were subtracted from Indicated Mineral Resources. The average grade for Measured and Indicated Resources exclusive of Mineral Reserves was back-calculated based on the remaining brine volume and lithium mass. |

Cauchari Lithium Brine Project
SEC Technical Report Summary
1.7 | Mineral Reserve Estimate |
1.7.1 | Inputs and Estimation Methodology |
A numerical groundwater flow and transport model using the FEFLOW 7.1 code was developed for the Cauchari Project in support of this PFS. The numerical model was built, calibrated, and operated by the DHI Group with the guidance of Mr. F. Reidel AIPG. The specific objectives of the model in support of this PFS are to:
● | Calibrate the model to a normalized root mean squared error (NRMSE) of 10% or less under pre-mining, steady-state conditions. |
● | Calibrate the model in transient mode for pumping tests at wells CAU07R and CAU11R. |
● | Simulate brine abstraction of the wellfields located in the NW- and SE Sectors of the Project area to support an annual LCE production of 25,000 tonnes over a 30-year mine life, assuming 67 percent total lithium process recovery efficiency. |
● | Evaluate preliminary well-field configurations and pumping schedules to minimize the potential dilution of lithium concentrations in the discharge of the production wells. |
● | Prepare an estimate of Mineral Reserves for the Project. |
The calibrated model was used to predict lithium extraction rates from the Salar de Cauchari during the proposed 30-year mine life with a target lithium carbonate equivalent (LCE) extraction rate of 25 kilotonnes per year (ktpy) assuming a process lithium recovery efficiency of 67%. Twenty-two (22) wells are proposed for the NW Sector wellfield in the Archibarca fan area during the first nine years of mine life. The NW production wells target the brine in the lower part of the Archibarca unit. During the initial three-year ramp-up period, the combined pumping rate increases from 168 l/s in Year 1 to 312 l/s during Year 3.
Forty-five (45) wells are proposed for the SE Sector wellfield with a pumping schedule. As for the NW wellfield, production wells are replaced on a regular basis during the LOM. The SE wellfield targets brine in the halite, clay, and Lower Sand units from Year 9 to Year 30 of operations. The proposed total pumping rate from the southeast wells is a constant 480 l/s.
The initial Li concentration in the pumped brine from the NW wellfield is 580 mg/l in Year 1 and gradually declines to 520 mg/L by Year 8. The initial Li concentration of the brine pumped from the SE wellfield gradually declines from 490 mg/l in Year 9 to 465 mg/l in Year 30. The resulting Li concentrations applied are: 580 mg/l for Years 1-5, 545 mg/l for Years 6-9, and 490 mg/l for Years 9 – 31. It is expected that through further optimization of the well-field configurations and pumping schedules, the overall LOM Li concentrations can be improved.
Cauchari Lithium Brine Project
SEC Technical Report Summary
1.7.2 | Mineral Reserve Classification |
Proven Reserves were derived from the Measured Resources in the NW wellfield area during the first seven years of production (with production in the NW extending for 9 years). Lithium Reserves derived after Year 7 from the Measured and Indicated Resources in the NW and SE wellfield areas were categorized as Probable Reserves. Results of a separate model simulation to evaluate the potential effect of the proposed neighboring LAC brine production (according to LAC Updated Feasibility Study of January 2020) showed that there is no material impact on the Cauchari Reserve Estimate. Table 1-4 shows the Mineral Reserve Estimate for the Cauchari Project.
It is the opinion of the QPs that the FEFLOW model provides a reasonable representation of the hydrogeological setting of the Project area and that the model is adequately calibrated to be an appropriate tool to estimate the Proven and Probable Reserves reported hereinafter. To the extent known by the QPs, there are no known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors that could affect the Mineral Reserve estimate which are not discussed in this Report.

2. | The Qualified Person(s) for these Mineral Resources and Mineral Reserves estimate is Mr. F. Reidel AIPG for Cauchari. |
3. | Comparison of values may not add up due to rounding or the use of averaging methods. |
4. | Lithium is converted to lithium carbonate (Li2CO3) with a conversion factor of 5.323. |
5. | The cut-off grade used to report Cauchari Mineral Resources and Mineral Reserves is 300 mg/l. |
6. | Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability, there is no certainty that any or all of the Mineral Resources can be converted into Mineral Reserves after application of the modifying factors. |
7. | The Lithium Reserve Estimate represents the lithium contained in the brine produced by the wellfields as input to the evaporation ponds. Brine production initiates in Year 1 from wells located in the NW Sector. In Year 9, brine production switches across to the SE Sector of the Project. |
8. | Approximately 25% of M+I Resources are converted to Total Reserves. |
9. | Potential environmental effects of pumping have not been comprehensively analyzed at the PFS stage. Additional evaluation of potential environmental effects will be done as part of the next stage of evaluation. |
10. | Additional hydrogeological test work will be required in the next stage of evaluation to adequately verify the quantification of hydraulic parameters in the Archibarca fan area and in the Lower Sand unit as indicated by the sensitivity analysis carried out on the model results. Mineral Reserves are derived from and included within the M&I Resources in the Resource Table 1-2 above. |
11. | Indicated Resources of 894,000t LCE contained in the West Fan Unit are not included in this PFS production profile. There is a reasonable prospect that through additional hydrogeological test work Inferred Resources in the Lower Sand Units will be converted to M+I Resources. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
Regarding risk factors, the Brine Reserve estimate may be affected by the following:
● | Assumptions regarding aquifer parameters and lithium concentrations used in the groundwater model for areas where empirical data does not exist. |
● | Estimated vertical hydraulic conductivity values which partially control the amount of anticipated future dilution in the NW areas where freshwater overlies brine. |
1.8 | Mine Design |
1.8.1 | Production Plan |
The production plan ramps up for the first three years to the peak 25,000 tpy by year 4. Production is maintained at a steady state for years 4 – 30. Cumulated production over the life of mine is in line with the Lithium Reserve Estimate.
1.9 | Infrastructure |
Site infrastructure will consist of the main processing facilities including brine well fields and pumping, evaporation ponds, process plant, and waste storage. The processing facilities will be supported by services and personnel accommodation facilities.
The brine production wellfields will be located on two sectors of the Salar de Cauchari, one in the Archibarca area, near and among the initial evaporation ponds and another located south-east. Brine wells will be equipped with variable-speed drive submersible pumps and surface booster stations to deliver brine to the evaporation ponds.
The evaporation ponds will cover an area of approximately 10.5 km2 in Years 1-5, increase to 11.3 m2 for years 6-9, and 12.2 m2 from year 10 onwards.
The processing plant will consist of a liming plant to support evaporation pond processes, and a lithium carbonation plant to produce the final product. The processing plant will be supported by service infrastructure such as reagents mixing, fuel and storage facility, sulfuric acid preparation, compressors and boilers, and water treatment plants.
The Project’s accommodation camp will be built to the west of the lithium carbonate plant, at a reasonable distance. The camp will include several facilities of modular-type construction including dormitories, dining rooms, recreational areas, and medical facilities.
During the construction phase, additional temporary modular facilities will be employed to expand the temporary peak labor requirements.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The process facility, support services, and accommodation infrastructure are deemed adequate to support the planned facility operation and production rate.
1.10 | Environmental, Social and Permitting |
1.10.1 | Environmental Liabilities |
The Project tenements are not subject to any known environmental liabilities. There have been historical ulexite / borax mining activities adjacent to the Project in the north of the Salar. These mining operations are generally limited to within three meters of the surface, and it is assumed that these borax workings will naturally be reclaimed when mining is halted due to wet season inflows.
1.10.2 | Base line studies |
The Project has successfully completed various environmental studies required to support its exploration programs between 2011 and the present. The last Environmental Impact Assessment approval was in 2017 for the exploration stage.
In September 2019 the Project submitted an Environmental Baseline for the Exploitation stage which to date is under evaluation by the provincial mining authority.
All the Environmental Impact Assessments are submitted to the Provincial Mining Directorate and subject to a participatory evaluation and administrative process with provincial authorities (Indigenous People Secretariat, Water Resources Directorate, Environmental Ministry, Economy, and Production Ministry, among others) and communities of influence, until the final approval resolution is obtained.
In the case of Cauchari, the evaluation process is carried out with the participation and dialogue of the indigenous communities of Manantiales de Pastos Chicos, Olaroz Chico, Huancar, Termas de Tuzgle de Puesto Sey, Catua, Paso de Jama and Susques.
The Project has submitted an initial mine closure plan within the Exploitation Environmental Impact Assessment which is still under evaluation.
1.10.3 | Permit Status |
Exploration and mining activities are subject to regulatory approval following an environmental impact assessment (“EIA”), before initiating disturbance activities. The QPs understand that Allkem (previously AAL) obtained all required approvals for the exploration drilling and testing programs in the Salar.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Allkem is currently in the process of renewing and maintaining required exploration-related permits while awaiting approval of exploitation permitting. Further permits will be required once exploitation is initialized.
There are no insurmountable risks identified at this time that could cause the project to not proceed into potential exploitation.
1.10.4 | Social and community requirements |
Allkem has been actively involved in community relations since the properties were acquired by SAS prior to initial drilling on the Project in 2011. Although there is minimal habitation in the area of the Salar, Allkem has consulted extensively with the local communities and employs members of these communities in the current exploration activities.
The formal EIA permitting process will address community and socio-economic issues; it is expected the Project will have a positive impact with the creation of new employment opportunities and investment in the region. As part of the EIA, a comprehensive consultation was undertaken with members of the local communities, regarding the Project development and its associated opportunities for the community members.

SEC Technical Report Summary
1.13.1 | Sensitivity Analysis |
The sensitivity analysis examined the impact of variations in commodity prices, production levels, capital costs, and operating costs on the project’s NPV at a discount rate of 10%.
The commodity price has the most significant impact on the project’s NPV, followed by production levels, OPEX, and CAPEX. Price emerges as the most influential factor and a mere 10% variation in price results in a 19% impact on the NPV see Figure 1-1 Even under adverse market conditions, such as unfavorable price levels, increased costs, and investment challenges, the Cauchari project remains economically viable.
Figure 1-1 – Sensitivity Chart.
Based on the assumptions detailed in this report, the economic analysis of the Cauchari Project demonstrates positive financial outcomes. The sensitivity analysis further strengthens the project’s viability, as it indicates resilience to market fluctuations and cost changes.

SEC Technical Report Summary
1.14 Conclusions and QP Recommendations
1.14.1 | Conclusions |
Based on the analyses and interpretation of the results of the exploration work carried out on the Cauchari Lithium Project between 2011 and 2018 and subsequent analysis, the salar geometry, brine chemistry composition and the specific yield of the salar sediments have been adequately defined to support the Measured, Indicated and Inferred Resource estimates described in Table 1-2.
It is the opinion of the QPs that the FEFLOW groundwater flow and transport model prepared for the Project provides a reasonable representation of the hydrogeological setting of the Project area and that the model is adequately calibrated to be used for the preparation of the Mineral Reserve estimate presented in Table 1-4.
Environmental Impact Assessment report was lodged with the Authorities in September 2019, with outcomes pending. No other insurmountable permitting-related risks are known that may cause the project not to proceed into exploitation.
Lithium marketing publications, such as the one that provided the prices in this study, currently acknowledge certain price profiles over the short, medium, and long term. The current pricing estimates indicate strong future demand and related price growth. The estimated CAPEX and OPEX for a 25,000 tpy conventional lithium carbonate production facility, including brine extraction, solar evaporation ponds, lithium carbonate processing, and auxiliary equipment, as well as infrastructure, is concluded and a pre-feasibility study, AACE class 4 level with a +/- 25% accuracy level. Given that Project economic results remain positive, even when enduring substantial negative variations in prices or cost drivers, it can be asserted that the Project shows reasonable economic extraction potential.
1.14.2 | Recommendations |
Considering that:
a) | The Project’s resource base appears sufficient for the proposed production program. | |
b) | Production of lithium carbonate from these Resources also appears feasible. | |
c) | Project economic evaluation results appear favorable, |
It is recommended that the Project proceed to the next study stage.
The trade-off study work completed during the current study indicated a preference to produce lithium carbonate on site, and a decision in this sense was taken by Allkem (previously AAL), discarding the production of lithium hydroxide or a mix of the two products. It is recommended that this assumption be

reviewed and reaffirmed at the next study phase, taking the development of nearby Allkem’s Olaroz plant into account.
Ongoing monitoring of market forces is recommended to ensure the economic viability of the Project remains.
It is recommended that the next study development phase include:
● | Expanding the Project’s Resources through the conversion of Inferred Resource in the Lower Sand unit into Indicated or Measured Resources. | |
● | Additional hydrogeological test work in the NW and SE wellfield areas to facilitate the optimization of hydraulic parameter selection and to reduce the uncertainty associated with production and construction. | |
● | Additional hydrogeological test work in the West Fan unit to be able to incorporate a significant amount Indicated Resources into the Project’s Mineral Reserve base and production profile. | |
● | Update the FEFLOW groundwater flow and transport model to optimize wellfield configurations, pumping schedules, optimize LOM Li concentrations, and to expand the Project’s mineral reserve base. |

2.2.2 | Site Visits |
Frederik Reidel last visited the Cauchari site in August 2019. Specific work carried out during the visit included review of the execution of QA/QC protocols for drilling, brine sampling, pump testing, and the preparation of drainable porosity samples. Drill cuttings and core were inspected and cross-checked with the Leapfrog model. Meetings with site geologists and management.
Mr. Marek Dworzanowski last visited the Cauchari Project area in July of 2018:
● | July 18 – meeting to discuss project background and site visit arrangements with the Advantage Lithium project geologist. |
● | July 19 – there was a visit to Salar de Cauchari and to the Orocobre Olaroz operation. At Salar de Cauchari the camp was visited. The staff at the camp were asked about sampling and analysis for the Cauchari project. The Salar was visited to inspect the exploration done as well as ongoing exploration. The extent of the Salar was noted and the potential locations for future evaporation ponds and the main plant area were also visited. Permission was obtained beforehand to visit the Orocobre Olaroz operation. Given Orocobre’s part ownership of the Cauchari project and the proximity of the Olaroz operation to the Cauchari Salar, a visit was viewed as essential to understanding the Cauchari project. Unfortunately, the weather prevented any viewing of the evaporation ponds, but the lithium carbonate plant was visited. The process was explained and questions about the process and plant design were answered. |

SEC Technical Report Summary
2.7 | Specific Characteristics of Lithium Brine Projects |
Although extensive exploration and development of new lithium brine projects has been underway for the last decade it is important to note there are essential differences between brine extraction and hard rock lithium, base, or precious metal mining. Brine is a fluid hosted in an aquifer and thus can flow and mix with adjacent fluids once pumping of the brine commences. An initial in-situ resource estimate is based on knowledge of the geometry of the aquifer, and the variations in porosity and brine grade within the aquifer.
Brine deposits are exploited by pumping the brine to the surface and extracting the lithium in a specialist production plant, generally following brine concentration through solar evaporation in large evaporation ponds. To assess the recoverable reserve, further information on the permeability and flow regime in the aquifer and the surrounding area is necessary to be able to predict how the lithium contained in brine will change over the Cauchari Project life. These considerations are examined more fully in Houston et. al., (2011) and in the Canadian Institute of Mining (CIM) and Joint Ore Reserve Committee (JORC) (Australia) brine reporting guidelines. The reader is referred to these key publications for further explanation of the details of brine deposits.
Hydrogeology is a specialist discipline which involves the use of specialized terms which are frequently used throughout this document. The reader is referred to the glossary for definition of terms.

3. | Property Description |
3.1 | Property Location, Country, Regional and Government Setting |
3.1.1 | Location |
Cauchari (latitude 23° 29’ 13.19” South, longitude 66° 42’ 34.30” West), which is located immediately south of, and has similar brine characteristics to, Olaroz, is wholly owned by Allkem. Cauchari is located in the Puna region, 230 kilometers west of the city of San Salvador de Jujuy in Jujuy Province of northern Argentina and is at an altitude of 3,900 meters above sea level. The Cauchari tenements cover 28,906 ha and consist of 22 mining concessions. Cauchari was acquired by Orocobre in 2020 following the completion of a statutory plan of arrangement with AAL, and then Cauchari was acquired by Allkem in 2021 pursuant to the Galaxy/Orocobre Merger. Refer to Figure 3-2.
The Project site is situated to the south of paved Hwy. 52 that passes through the international border with Chile, approximately 80 km west (Jama Pass) and continues on to the major mining center of Calama and the ports of Antofagasta and Mejillones in northern Chile, both major ports for the export of mineral commodities and import of mining equipment.
3.1.2 | Government Setting |
The Project is subject to the governing laws of Argentina, and provincial laws of Jujuy province.

Co-ordinates are given in the Argentine coordinate system, which uses the Gauss Krueger Transverse Mercator projection and the Argentine Posgar 94 datum. The properties are located in Argentine GK Zone 3. All other map co-ordinates used in this report are Posgar 94 except where noted.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Two tenement types exist in the Argentine mining regulations. Cateos (Exploration Permits) are licenses that allow the holder to explore the tenement for a period of time that is proportional to its size. An Exploration Permit of 1 unit (500 hectares) is granted for a period of 150 days. For each additional unit (500 hectares) the period is extended by 50 days. The maximum allowed permit size is 20 units (10,000 hectares) and which is granted for a period of 1,100 days. The period begins 30 days after granting the permit.
A relinquishment must be made after the first 300 days, and a second one after 700 days. The applicant should pay a canon fee of $1,600 Argentine pesos per unit (500 hectares) and submit an exploration work plan and environmental impact assessment.
Minas (Mining/exploitation Permits) are licenses which allow the holder to exploit the property (tenement) subject to regulatory environmental approval. Minas are of unlimited duration, providing the property holder meets its obligations under the Mining Code. These include:
● | Paying the annual rent (canon). |
● | Completing a survey of the property boundaries. |
● | Submitting a mining investment plan. |
● | Meeting the minimum investment commitment. |

Figure 3-3 – Location map of the Cauchari properties.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The Cauchari properties are now all held as applications for mines.
● | The investment commitment is 300 times the annual rent payment, to be spent over a five-year period and payable within five years of the filing of a capital investment plan. |
● | During each of the first two years the amount of the investment shall not be less than 20% and the rest of the investment (60 %) freely distributed during the remaining three years. |
● | The annual tenement tax varies according to the mineral commodity. For brines it is $3,200 Argentine pesos/yr per 100 hectares. |
Mining properties (of both types) must specify the type of mineral the holder is seeking to explore and exploit. The canon fees are dependent on the class of minerals applied for. Properties cannot be over-staked by new properties specifying different minerals; adding a new mineral species to a properties file is a relatively straightforward procedure and may require payment of a different canon fee.
All Cauchari properties are in the process of being granted as minas/exploitation permits, replacing the Cateos previously held by SAS. Provided that the title holder fulfils the legal requirements, in due time the pertinent exploitation license/property should be granted. An independent legal review has confirmed the property obligations have been met and that the properties are in good standing.
3.1.4 | The Cauchari Tenement Package |
The Cauchari tenements cover approximately 28,906 hectares in the province of Jujuy. These consist of 22 minas which were applied for on behalf of SAS. There is an agreement between the vendors of these properties (tenements) and SAS. The legal report prepared by independent Argentine registered lawyer Mr. Santiago Saravia Frias (dated August 12, 2016) showed that these properties were originally owned by Silvia Rodriguez and were transferred to SAS (effective date October 9, 2015).

3.1.5 | Mineral Rights and Permitting |
Authorizations are required to commence mining activities, primarily the submission and approval of a full Environmental Impact Assessment for the Cauchari Project. Allkem has submitted the last environmental impact assessment in 2019 for exploitation phase included necessary infrastructure such pumping wells, construction of the processing plant, gas pipeline and aqueduct lines, camp, among other activities. The approval of this Environmental Impact Assessment must be issued by the provincial mining authority and can be renewed by SAS for up to two years thereafter, if not sooner.
To date, Allkem has obtained in 2017 the exploration phase permit and, in addition to this mining approval, there are other environmental permits described below.
3.1.6 | Agreements and Royalties |
The Argentine federal government regulates the ownership of Mineral Resources, although mining properties are administered by the provinces. Therefore, and in accordance with the Jujuy Provincial Constitutional Law, Provincial Law 5791/13, Resolution 1641-DPR-2023 and other related regulatory decrees and complementary rules, SAS will be required to pay monthly royalties as consideration for the minerals extracted from its concessions. Monthly royalties are equivalent to 3% of the mine head value of the mineral extracted, calculated as the sales price less direct cash costs related to exploitation and excluding depreciation of fixed assets.
Cauchari Lithium Brine Project
SEC Technical Report Summary
SAS expects to pay the Province of Jujuy a royalty of the type once the approval of the Exploitation Environmental Impact Assessment has been approved and the exploitation and production activities have effectively started.

Cauchari Lithium Brine Project
SEC Technical Report Summary
3.2 | Environmental Liabilities |
The Cauchari tenements are not subject to any known environmental liabilities. There have been historical ulexite / borax mining activities adjacent to the Cauchari in the north of the salar. These mining operations are generally limited to within three meters of the surface, and it is assumed that these borax workings will naturally reclaim when mining is halted due to wet season inflows.
3.3 | Other Significant Factors and Risks |
Several normal risk factors are associated with the exploration and development of the Cauchari JV. These risks include, but are not limited to:
● | Mining properties may not be renewed by the provincial authorities. |
● | Final environmental approvals may not be received from the necessary authorities. |
● | Obtaining all necessary licenses and permits on acceptable terms in a timely manner or at all. |
● | Changes in federal or provincial laws and their implementation may impact planned activities. |
● | Potential flooding in the salar could temporarily delay planned exploration and development activities. |
● | The company may be unable to meet its obligations for expenditure and maintenance of property licenses. |
● | Activities on adjacent properties having an impact on the Cauchari. |

SEC Technical Report Summary
4. | Accessibility, Climate, Physiography, Local Resources, and Infrastructure |
This section discusses the environment and geographical phenomena associated with the project site.
4.1 | Accessibility |
The Project site is reached by paved and unpaved roads from either the Salta or Jujuy Provinces. The distance between San Salvador de Jujuy and the Project is approximately 230 km and takes about 4 hours by car. The access from Jujuy is via Hwy RN 9 for approximately 60 km to the town of Purmamarca, from there Hwy RN 52 for a further 150 km, passing the village of Susques to RP 70 along the west side of Cauchari. The Cauchari JV is accessed directly from RP 70.
The Project is reached from the city of Salta, capital of Salta Province, via the town of Campo Quijano, then continuing along Hwy RN 51 through Quebrada del Toro, the town of San Antonio de los Cobres and a further 130 km to the junction with RP 70 on the west side of Salar de Cauchari. Total driving time from Salta to the Project is approximately 5 hours.
Both Jujuy and Salta have international airports with regular flights to Buenos Aires. The Project is located 20 km to the south of Orocobre’s Olaroz lithium plant which has full infrastructure available including water, gas, and electricity. The Puna gas pipeline crosses to the north of Salar de Olaroz. Orocobre has constructed a connection to this pipeline for the Olaroz Project. A railway line connecting northern Argentina to Chile passes along the southern end of Salar de Cauchari, approximately 40 kilometers to the south of the Project site.
4.2 | Topography, Elevation, Vegetation and Climate |
4.2.1 | Physiography |
The Altiplano-Puna is an elevated plateau within the central Andes (see Figure 4-2 below). The Puna covers part of the Argentinean provinces of Jujuy, Salta, Catamarca, La Rioja, and Tucuman with an average elevation of 3,700 masl (Morlans, 1995; Kay et. al., 2008).
Cauchari Lithium Brine Project
SEC Technical Report Summary
Figure 4-1 – Project location, access, and infrastructure.
The Altiplano-Puna Volcanic Complex (APVC) is shown on Figure 4-2 and is associated with numerous stratovolcanoes and calderas. Investigations have shown that the APVC is underlain by an extensive magma chamber at 4-8 km depth (de Silva et al., 2006).
The physiography of the region is characterized by generally north-south trending basins and ranges, with canyons cutting through the Western and Eastern Cordilleras. There are numerous volcanic centers in the Puna, particularly in the Western Cordillera, where volcanic cones are present along the border of Chile and Argentina.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Dry salt lakes (salars) in the Puna occur within many of the closed basins (see Figure 4-2 below), which have internal (endorheic) drainage. Inflow to these salars is from summer rainfall, surface water runoff and groundwater inflows. Discharge is though evaporation.

Figure 4-2 – Physiographic and morphotectonic features of the Central Andes.
Key physiographic observations regarding salar de Cauchari include:
● | The drainage divides between the Cauchari salar to the south and salar de Olaroz to the north is coincident with the international Hwy RN 52 crossing between these salars and continuing west to link Argentina to Chile at the Jama pass. |
● | The large Archibarca alluvial fan is present on the western side of Salar de Cauchari. The eastern side of the salar hosts smaller alluvial fans entering the basin. |
● | Rio Tocomar enters from the south into the Cauchari basin and flows north towards the nucleus of the salar. Hot springs are reported in the head water of the river in the southeastern extent of the basin. |
● | Rio Ola enters the Cauchari-Olaroz drainage basin from the west and sits on top of the Archibarca Fan. |
● | Rio Rosario enters the Salar de Olaroz from the north and flows south towards the center of the Salar. |
● | The Cauchari – Olaroz drainage basin covers some 6,000 km2 with the nucleus of Salar de Cauchari covering approximately 250 km2 as shown in Figure 4-3. |

4.2.2 | Climate |
The climate in the Project area is severe and can be described as typical of a continental, cold, high-altitude desert, with resultant scarce vegetation. Daily temperature variations may exceed 25°C. Solar radiation is intense, especially during the summer months of October through March, leading to high evaporation rates. The rainy season is between the months of December to March. Occasional flooding can occur in the salar during the wet season.
SAS has had access to three operating weather stations since 2012, one station located in Salar de Cauchari, and two stations located further north in Salar de Olaroz. The stations maintain a continuous record of temperature, atmospheric pressure, and liquid precipitation, among other meteorological variables of interest. There is no continuous record of direct evaporation measurements, and therefore evaporation is calculated indirectly from other parameters.
In addition to these stations, the National Institute of Agricultural Technology INTA has historical monthly rainfall data in northwestern Argentina, for the period 1934-1990 (Bianchi, 1992), of which three stations are located within the Cauchari-Olaroz basin.
The locations of the relevant weather stations for the Project are shown in Figure 4-4 and Table 4-1 provides summary information for each of the stations.

4.2.3 | Precipitation |
The rainy season is between the months December and March when most of the annual rainfall occurs often in brief convective storms that originate from Amazonia to the northeast. The period between April and November is typically dry. Annual rainfall tends to increase towards the northeast, especially at lower elevations. Significant control on annual rainfall is exerted by ENSO (El Niño-Southern Oscillation) (Houston, 2006a) with significant yearly differences in rainfall linked to ENSO events. Table 4-2 shows the average monthly rainfall data for the six relevant weather stations for the Project area and Figure 4-5 shows an isohyet map. The average annual precipitation is approximately 75 mm for the Project site. Figure 4-6 shows the average monthly precipitation distribution throughout the year.

4.2.5 | Evaporation |
Evaporation test work has not been carried out at the Cauchari Project location. A detailed evaporation test work plan was carried out at the Salar de Olaroz, situated within 30 km. Mr. F. Reidel AIPG (the QP), is of the opinion that the Olaroz test work is a suitable approximation for the Cauchari Project site.
Various approaches have been carried out to determine the evaporation for Salar de Olaroz and these approaches can be extrapolated to Salar de Cauchari. Measurements for Salar de Olaroz include sampling and monitoring of fresh water and brine Class A evaporation pans since 2008. Table 4-4 shows the results of the Olaroz work.

The pan evaporation data are plotted in Figure 4-9 and show that the maximum evaporation rates occur during October, November, and December. During the summer months, a decrease in wind speed and increase in cloud cover tend to decrease the effective evaporation. The minimum evaporation takes place during the winter months, when lower temperatures have a direct impact on evaporation. The data also shows that the evaporation of brine is lower than freshwater with differences of 21% in winter months and up to 47% in the summer months.

4.2.6 | Vegetation and Wetlands |
Due to the extreme weather conditions in the region, the predominant vegetation is of the high-altitude xerophytic type adapted to high levels of solar radiation, winds and severe cold. The vegetation is dominated by woody herbs of low height from 0.40 – 1.5 m, grasses, and cushion plants. With high salinity on its surface, the nucleus of the salar is devoid of vegetation.
In compliance with local regulations, Allkem has completed biannual environmental monitoring with the last survey completed in April 2019.
4.3 | Local Infrastructure and Resources |
There are several local villages within 50 kilometers of the Project site. These include: Catua 37 km southwest, Pastos Chicos and Puesto Sey to the east and Olaroz Chico 34 km north and Olacapato 50 km south. The regional administration is located in the town of Susques (population ~2,000) some 60 km northeast of the Project site. Susques has a regional hospital, petroleum, and gas services, and several hotels. A year-round camp exists at the Project site and provides all services and accommodations for the on-going exploration program.

SEC Technical Report Summary
5. | History |
This section describes historical exploration activities at the Project site.
5.1 | Historical Exploration and Drill Programs |
Salars in the Puna have historically been exploited for salt (halite) and for borates (typically ulexite); Salar de Cauchari was no exception. Exploration and exploitation efforts were generally limited to the upper three meters of the salar surface. Historical production levels of borates were generally not documented and therefore are unknown. Lithium and potassium have not been exploited on the Project mineral properties.
Fabricaciones Militares (an Argentine government agency) carried out sampling of brines from the Argentine salars in the Puna during the 1970’s. The presence of anomalous Li values was detected at that time when only salt and borates were exploited.
Initial evaluation of the mineral potential of salars in Northern Argentina was also documented by Igarzábal (1984) as part of the Instituto de Beneficios de Minerales (INBEMI) investigation carried out by the University of Salta. This investigation involved limited sampling of Li, K, and other elements; Salar de Cauchari showed some of the highest lithium values of 0.092% Li (and 0.52% K).
5.2 | History of Cauchari Ownership |
The following is an overview of the history of the ownership of the mineral properties that now comprise the Cauchari JV:
● | Historic borate mining was carried out in the Cauchari Salar by Borax Argentina, which is now owned by Orocobre. |
● | The Cauchari properties were acquired by Mr. Miguel Peral and Mrs. Silvia Rodriguez through direct property staking (not through third-party purchases). |
● | Peral and Rodriguez subsequently contributed these properties to the formation of South American Salars Pty Ltd (SAS) in return for a 15% ownership in this Australian registered company. SAS is majority owned by Orocobre (85%). |
● | Orocobre and SAS agreed to a joint venture with Advantage Lithium Corp (AAL) in November 2016. |
● | Orocobre acquired all outstanding shares of ALL on February 19, 2022. |
● | Orocobre and Galaxy lithium merged on 25 August 2021 to form Allkem Ltd (Allkem). Allkem owns 100% of the Cauchari project through the mentioned subsidiaries. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
5.3 | 2009-2011 SAS Exploration |
● | Geochemical sampling in 2009 consisting of 134 brine samples from 105 pits showed that the northern part the salar had the most elevated lithium concentrations. |
● | 2009 geophysical surveys undertaken by Orocobre in Cauchari consisted of three coincident gravity and AMT lines aimed at mapping the basin geometry and depth. |
● | Five diamond holes and one rotary hole were drilled in the SE Sector of the Cauchari JV to a maximum depth of 248 m in 2011. Drilling equipment did not perform as required, with two of the holes abandoned at <100 m depth and only one hole reaching the target depth for the program. |
● | An initial inferred resource of 470,000 t of lithium carbonate equivalent (LCE) was defined from the 2011 drilling program with a NI 43-101 technical report issued in December 2016 outlining the results of the previous exploration. |
● | Exploration work by AAL under the joint venture agreement with Orocobre was started in 2017. |

SEC Technical Report Summary
6. | Geological Setting, Mineralization and Deposit |
6.1 | Regional Geology |
Salar de Cauchari is located towards the center of the Puna Plateau. The Puna is an elevated plateau in northern Argentina which has been subject to uplift along thrust systems inverting earlier extensional faults. The Puna is host to numerous large ignimbrites and stratovolcanoes. A summary evolution of the Puna is shown in Figure 6-1 after Houston (2010b).
6.1.1 | Jurassic-Cretaceous |
The Andes have been part of a convergent plate margin since the Jurassic with both a volcanic arc and associated sedimentary basins developed as a result of eastward dipping subduction. The early island arc is interpreted to have formed on the west coast of South America during the Jurassic (195-130 Ma), progressing eastward during the mid-Cretaceous (125-90 Ma) (Coira et al., 1982).
An extensional tectonic regime existed through the late Cretaceous, generating back-arc rifting and grabens (Salfity & Marquillas, 1994). Marine sediments of Jurassic to Cretaceous age underlie much of the Central Andes.
6.1.2 | Late Cretaceous to Eocene |
During the late Cretaceous to the Eocene (~78-37 Ma), the volcanic arc migrated east to the position of the current Precordillera (Allmendinger et al, 1997). Significant crustal shortening occurred during the Incaic Phase (44-37 Ma), (Gregory-Wodzicki, 2000) forming a major north-south watershed, contributing to the formation of coarse clastic continental sediments.
Initiation of shortening and uplift in the Eastern Cordillera of Argentina around 38 Ma, contributed to forming a second north-south watershed, with the accumulation of coarse continental sediment throughout the Puna (Allmendinger et al., 1997).
6.1.3 | Oligocene to Miocene Volcanism |
By the late Oligocene to early Miocene (20-25 Ma), the volcanic arc switched to its current location in the Western Cordillera. At the same time, significant shortening across the Puna on reverse faults led to the initiation of separated depo-centers (Figure 6-1). Major uplift of the Altiplano-Puna plateau began during the middle to late Miocene (10-15 Ma), perhaps reaching 2,500 m by 10 Ma, and 3,500 m by 6 Ma (Garzione et al., 2006). Coutand et. al. (2001) interprets the reverse faults as being responsible for increasing the accommodation space in the basins by uplift of mountain ranges marginal to the Puna Salar basins. This is confirmed by the seismic section across Olaroz to the north of Cauchari (Figure 6-1).
Cauchari Lithium Brine Project
SEC Technical Report Summary
Late Miocene volcanism at 5-10 Ma in the Altiplano-Puna Volcanic Complex (APVC) between 21o-24o S (de Silva, 1989), erupted numerous ignimbrite sheets, with associated caldera subsidence, and the formation of andesitic to dacitic stratovolcanoes. This volcanic activity was often constrained by NW-SE trending crustal mega-fractures, which are particularly well displayed along the Calama-Olacapato-El Toro lineament passing to the south of Salar de Cauchari (Salfity & Marquillas 1994; Chernicoff et al., 2002).
6.1.4 | Oligocene to Miocene Sedimentation |
During the early to middle Miocene red bed sedimentation is common throughout the Puna, Altiplano and Chilean Pre-Andean Depression (Jordan & Alonso, 1987). This suggests continental sedimentation was dominant at this time. With thrust faulting, uplift and volcanism intensifying in the mid to late Miocene, sedimentary basins between the thrust sheets became isolated by the thrust bounded mountain ranges. At this stage the basins in the Puna developed internal drainages, bounded by major mountain ranges to the west and east.
Sedimentation in the basins consisted of alluvial fans forming from the uplifting ranges with progressively finer sedimentation and playa sands and mudflat sediments deposited towards the low energy centers of the basins. Alonso et.al., (1991) note there has been extensive evaporitic deposition since 15 Ma, with borate deposition occurring for the past 7 to 8 Ma.
Hartley et al., (2005) suggest Northern Argentina has experienced a semi-arid to arid climate since at least 150 Ma as a result of its stable location relative to the Hadley circulation (marine current). Most moisture originating in Amazonia was blocked due to Andean uplift, resulting in increased aridity in the Puna from at least 10-15 Ma.
The high evaporation level, together with the reduced precipitation, has led to increased aridity and the deposition of evaporites in many of the Puna basins.
6.1.5 | Pliocene-Quaternary |
During the Pliocene-Pleistocene tectonic deformation took place as shortening moved east from the Puna into the Santa Barbara fault system. Coincident with this change in tectonic activity climatic fluctuation occurred with short wetter periods alternating with drier periods.
Cauchari Lithium Brine Project
SEC Technical Report Summary
As a result of both, reduced tectonic activity in the Puna and the predominant arid conditions, reduced erosion led to reduced sediment accumulation in the isolated basins. However, both surface and groundwater inflows into the basins continued the leaching, dissolution transportation and concentration of minerals. Precipitation of salts and evaporites occurred in the center of basins where evaporation is the only means of water escaping from the hydrological system.
Evaporite minerals (halite, gypsum) occur disseminated within clastic sequences in the salar basins and as discrete evaporite beds. In some mature salars such as Salar de Hombre Muerto and Salar de Atacama thick halite sequences have formed.
Stratovolcanoes and calderas, with associated ignimbrite sheet eruptions, are located in the Altiplano and Puna extending as far south as Cerro Bonete and the Incapillo caldera. The Altiplano-Puna Volcanic Complex (APVC), located between the Altiplano (Bolivia) and Puna (Argentina), is associated with numerous of these stratovolcanoes and calderas. De Silva et al., (2006) have shown the APVC is underlain by an extensive magma chamber at 4-8 km depth.

This section summarizes the deposit and geological setting of the Project.
The published geological maps covering the Cauchari area
are shown in Figure 6-3, with north-south trending belts of Ordovician and Cretaceous sediments forming the higher mountain ranges on the basin margins and younger Tertiary terrestrial sediments further within the basin, closer to the Cauchari Salar.
A description of individual geological units in the Cauchari basin is provided in the stratigraphic column in Table 6-1.
The information obtained from the detailed logs of the boreholes drilled during the 2011 and 2017/18 campaigns was used to prepare the geological sections shown in Figure 6-4 and Figure 6-5 The geological model is based on the interpretation of the logging that followed an internal classification system. Six major lithological units were identified and are included in the geological conceptual model as shown in Figure 6-4.

6.2.1 | Archibarca Fan Unit |
The Archibarca alluvial fan constitutes the NW boundary to the salt deposits within the Salar de Cauchari and covers a surface area of around 23.8 km² within the Allkem properties, extending north into properties owned by Allkem in Salar de Olaroz. This unit is the surface divide between the Salar de Olaroz basin to the North and the Salar de Cauchari basin to the South.
The boreholes (CAU07R, CAU17D, CAU18D, CAU20D and CAU21D) drilled on the Archibarca fan intercepted coarse materials (sandy gravels and gravelly sand with coarse sand levels), overlapping and inter-fingering at greater than 200 m depth with saline / lacustrine deposits (Clay and Halite Unit) as shown in Figure 6-5. This suggests that the Archibarca fan unit overlies salar sediments above this depth.
Figure 6-5 – W-E section looking north, showing the progressive inter-fingering of the Archibarca fan with the Clay and Halite units.
The unit is characterized by a thick sequence of coarse sediments consisting of medium to coarse gravels which in turn are formed by clasts of gray quartzite and greenish-white clasts of quartz, basalts and graywackes transported downslope from the west. The clasts range from sub-angular to rounded with the presence of medium to coarse sand in variable proportions and with the presence of clay in some sandy and/or gravelly levels as shown in Figure 6-6. The alluvial fan gravel is commonly interbedded with thick layers of medium to coarse sand inter-fingered with levels of clay.

6.2.2 | West Fan Unit |
The piedmont developed at the base of the mountain range that constitutes the western boundary of Salar de Cauchari is dominated by a series of small alluvial fans that inter-finger with the saline / lacustrine sediments (Clay Unit) of the salar as shown in Figure 6-7.
Boreholes CAU16D and CAU15D were drilled along the western boundary of the salar in the northern part of the West Fan. These boreholes intersected inter-fingering clayey levels (Clay unit) with thick intervals of sand and sandy silt and with a few levels of sandy gravel.
Boreholes CAU23D, CAU24D, CAU28D and CAU29D were drilled in the southern part of the West Fan and intersect thick levels of sand, silty sand, and gravel sequences at depth (200 m approx.) interbedded with clay and halite levels (CAU24D). The sequence of coarse materials (sands and gravels) becomes thicker towards the south (CAU29D) where wide alluvial fans develop extending to the maximum depth of drilling (404 m in CAU29).

Figure 6-7 – W-E section looking north between boreholes CAU16D and CAU10R.
The West Fan is dominated by fine to medium gray green to dark green sands with abundant presence of gypsum crystals (Selenite), quartz and dark lithic material. The sands are interbedded with levels of medium to coarse gravel with sub-rounded clasts in a sandy matrix formed by the greenish quartzites and volcanic lithic material, with fragments from 1 cm to 8 cm in size as shown in Figure 6-8.

6.2.3 | East Fan Unit |
The eastern boundary of the Cauchari basin is dominated by a series of fluvial/alluvial fans with a variable extension. Boreholes CAU01D, CAU02D, CAU05D, CAU10D, CAU14D, CAU22D, CAU26D/A and CAU27D intercept 3 m to 20 m thick layers of alternating friable dark sands to massive, cemented grits that are interpreted as distal facies of the fans seen along the eastern margin of the salar.
The East Fan unit is much more restricted in thickness and areal extent than the sequences observed along the western margin (West Fan Unit) with shallow/thinner sequences that overlie lacustrine / saline deposits.
Figure 6-7 and Figure 6-9 show overlapping sequences of the East Fan unit over the saline/ lacustrine units along the eastern margin of the basin.

SEC Technical Report Summary
Figure 6-9 – Section showing the interpreted geometry of the East Fan unit.
6.2.4 | Lower Sand Unit |
Boreholes CAU11R, CAU12D A, CAU13D A and CAU19D intersected a sand dominant unit at approx. 400 m depth. The bottom of this sand dominant unit was not defined in these boreholes (drilled up to 610 m depth) as shown in Figure 6-10. CAU15D on the western margin of the salar shows sand levels with similar features to those observed in the sands before-mentioned boreholes.
When incorporating additional borehole information from Lithium Americas Corp (LAC) it is possible to interpret the broad regional distribution of this unit which suggests that this unit may probably linked to the Archibarca Fan Unit. The supply of clastic sediments is wide enough to generate the volume of these basal sands that could be correlated to the deepest and transgressive section of the Archibarca Fan and possibly to a lesser extent to the West fans. In addition to this, a slope can be observed, at least at the top of this sandy sequence, which is deepening towards the south-central sector of the basin (CAU12D A, CAU13D A and CAU19D). This sandy unit could represent basal sedimentation of the basin on which the upper saline / lacustrine system, represented by the Clay and Halite Units, was developed.

Figure 6-10 – Section with the interpreted geometry of the Lower Sand unit.
The Lower Sand unit is characterized by medium, greenish gray to dark gray sand with abundant presence of friable gypsum (selenite) and lesser dark lithic and quartz crystals with some biotite (Figure 6-11). Some irregular layers with cemented carbonates or halite are also observed and that are interbedded with occasional thin reddish-brown sandy, silty, and clayey layers.

6.2.5 | Clay Unit |
The clay unit is widely distributed throughout Salar de Cauchari and was intersected in all boreholes in the SE Sector of the Project. The Clay unit is an irregular N-S elongated body and in some boreholes (CAU08R and CAU09R) can extend to below 300 m depth. It is mainly inter-fingered with the Halite unit. The Clay unit together with the Halite unit constitutes the saline / lacustrine sediments in the center of the salar as shown in Figure 6-12. The Clay unit appears to thicken towards the east of the salar.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Figure 6-12 – N-S section (looking NW) showing the distributions of the Clay and Halite units.
The Clay unit is mainly composed of reddish or reddish brown to brown clays (Figure 6-13), silty clays and/or limey clays, with a variable content of halite crystals and ulexite nodules. To a lesser degree, some black clayey levels with a presence of organic matter and green clays were recognized. It is commonly inter-fingered with some thin levels of fine to very fine sand. Numerous crystals of twinned gypsum (selenite) are locally present forming inter- grown polycrystalline aggregates.
Figure 6-13 – Example of the Clay unit (CAU12D: 177.5-179m).

SEC Technical Report Summary
6.2.6 | Halite Unit |
The boreholes in the SE Sector of the Project intersected numerous, thick, and extensive levels of halite with a variable content of clastic sediments (sands and clays). These levels are interpreted as an irregular body of crystalline halite that inter-fingers with the clays (Clay unit) described above. The Halite unit thins and becomes shallower towards the western margin of the salar.
The surface of the salar shows a very thin halite cover (a few centimeters thick) and immediately passes to the clay core (Clay unit). The first significant halite occurs between 20 m and 35 m deep, as shown in Figure 6-14. It has an estimated thickness of 300 m in CAU13D and over 500 m in CAU14D.
Figure 6-14 – NE-SW section looking west, showing the distribution of Halite and Clay units.
The Halite unit is characterized by massive crystalline halite or, to a lesser extent, friable aggregates of crystals that can exceed one centimeter in size (Figure 6-15), mainly with gray to reddish brown colors, according to the associated clastic sediments (fine sands with selenite and clays and silt-clays respectively). It is commonly inter-fingered with fine to very fine sand levels, of variable thickness, with abundant gypsum crystals (selenite) and clay layers with abundant presence of halite crystals. The halite is accompanied by crystals of mirabilite (sodium sulphate) and scarce ulexite (hydrated sodium calcium borate hydroxide). Some intervals of the halite (Figure 6-15) show enhanced permeability over the typical more compact halite material.

6.3 | Mineralization |
The brines from Cauchari are solutions saturated in sodium chloride with an average concentration of total dissolved solids (TDS) of 290 g/l. The average density is 1.19 g/cm3. The other components present in the Cauchari brine are K, Li, Mg, Ca, Cl, SO4 and B.
Table 6-4 shows a breakdown of the principal chemical constituents in the Cauchari brine including maximum, average, and minimum values, based on 546 brine samples used in the brine resource estimate herein that were collected from the 2011 – 2018 drilling programs.
Table 6-4 – Maximum, average, and minimum elemental concentrations of the Cauchari brine.
Figure 11-7 and Figure 11-8 show the kriged distribution of lithium and potassium concentrations in the salar. Typically, concentrations of lithium and potassium show a high degree of correlation. The kriged three-dimensional distribution of lithium and potassium concentrations were used in the updated resource model as further described in Chapter 11.
Brine quality is evaluated through the relationship of the elements of commercial interest lithium and potassium. Components of the brine that in some respect constitute impurities, include Mg, Ca and SO4. The calculated ratios for the averaged brine chemical composition are presented in Table 6-5.

As in other natural brines in the region, such as those of the Salar de Atacama and Salar del Hombre Muerto, the Cl–, SO4=, K+, Mg++, Na+ ion concentrations are used to follow the crystallization of salts during the evaporation process. The known phase diagram (Janecke projection) of the aqueous quinary system (Na+, K+, Mg++, SO4=, Cl–) at 25°C and saturated in sodium chloride can be used when adjusted for the presence of lithium in the brines. The Janecke projection of MgLi2-SO4-K2 in mol % is used to make this adjustment. The Cauchari brine composition is represented in the Janecke Projection diagram in Figure 6-16 along with the brine compositions from other salars. The Cauchari brine composition is compared with those of Silver Peak, Salar de Atacama, Salar del Hombre Muerto, Salar de Rincon and Salar de Uyuni in Table 6-6.

6.4 | Deposit Types |
Salars occur in closed (endorheic) basins without external drainage, in dry desert regions where evaporation rates exceed stream and groundwater recharge rates, preventing lakes from reaching the size necessary to form outlet streams or rivers. Evaporative concentration of surface water over time in these basins leads to residual concentration of dissolved salts (Bradley et al., 2013) to develop saline brines enriched in one or more of the following constituents: sodium, potassium, chloride, sulfate, carbonate species, and, in some basins, metals such as boron and lithium. Salar de Cauchari is a brine deposit with enriched concentrations of lithium and potassium.
Houston et al., 2011 identified, as shown in, Figure 6-17 two general categories of salars:
1. | mature, halite dominant (those containing extensive thicknesses – often hundreds of meters of halite, such as the Salar de Atacama, and the FMC Hombre Muerto operation). |
2. | Immature salars, which are dominated by clastic sediments with limited thicknesses of halite. |
Mature salt dominated salars can have high permeability and intermediate values of specific yield near surface, with both parameters decreasing rapidly with depth. In these salars the brine resource can be within 50 m below surface.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Immature salars conversely have porosity and permeability controlled by individual layers within the salar sequence. The porosity and permeability may continue to depths of hundreds of meters in clastic salars but can be highly variable due to differences between sand and gravel units and finer grained silts and clays. The presence of different stratigraphic units in clastic salars can result in a variable distribution of the contained brine.
Figure 6-17 – Model showing the difference between mature and immature salars.
Cauchari Lithium Brine Project
SEC Technical Report Summary
6.5 | Hydrogeology |
Salars generally consist of an inner nucleus of halite surrounded by marginal deposits of mixed carbonate and sulphate evaporites with fine grained clastic sediments. Coarser grained sediments generally occur on the margins of the basin, with successive inner shells of finer grained clastic units. Towards the center of the salar, sediments can show a progressive change from carbonate to sulphate and finally chloride evaporites (principally halite).
Drilling results in Cauchari to date have helped identify the following hydrogeological units:
● | Alluvial fans surrounding the salar. These are coarse grained and overall, highly permeable units that drain towards the salar. Groundwater flow is unconfined to semi-confined; specific yield (drainable porosity) is high. The water quality in the fans above the brine interface is fresh to brackish. The long-term CAU07 pumping test in the NW Sector (Archibarca Fan) has yielded positive results that are further discussed in Section 7.4.3. |
● | A clay unit. This clay unit covers a large area over the central part of the salar and is interpreted to extend below the alluvial fans. This clay unit has a low permeability and could locally form a hydraulic barrier. The clay contains brine in the central part of the salar. Fresh water may sit on top of this clay unit along the edges of the salar. |
● | A semi-confined to confined halite unit can be identified in the central portion of the salar where it underlies the clay unit. Locally, the halite unit is interbedded with fine grained sediment of the clay unit. Data collected to date suggests that the bulk halite unit is not very permeable, but interbedded coarser grained clastic layers can display locally high permeabilities as seen in the CAU11 pumping test. It is host to medium- to high lithium concentration brine. The results of the long-term CAU11 pumping test are further discussed in Section 7.4.3 below. |
● | A deep sand unit. This deep sand unit has been identified in four boreholes (CAU11, 12, 13 and 19) in the SE Sector at depths below 300 m, excluding holes that were drilled on platforms to intersect the sand at deeper levels (CAU12DA and 13DA). The unit appears to be relatively permeable based on pumping test results of CAU11 as discussed in Section 7.4 below. The deep sand hosts high quality lithium brine. |
6.6 | Drainable Porosity |
Porosity is highly dependent on lithology. Total porosity is generally higher in finer grained sediments, whereas the reverse is true for drainable porosity or specific yield since finer grained sediments have a high specific retention (portion of fluid that cannot be extracted). The lithology within the salar is variable with halite and halite mixed units, clay, and gravel- sand-silt-clay sized mixes spanning the full range of sediment types.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Drainable porosity analyses were carried out on undisturbed core samples by laboratories GSA, DBSA and the BGS. Based on the results of these analyses, drainable porosity values were assigned to the specific lithological units defined in the geological model as described in Section 6.2. Table 6-7 summarizes the results of the porosity analysis. The analysis of drainable porosity is further discussed in Section 8.
Table 6-7 – Results of drainable porosity analyses.
6.7 | Permeability |
Permeability (or hydraulic conductivity) is also a parameter that is highly dependent on lithology. Generally finer grained and well-graded sediments have a lower permeability than coarser grained poorly graded sediments. The permeability of halite can be enhanced though fracturing and solutions features. AAL has carried out pumping tests within the salar and LAC has carried out other pumping tests in the adjacent mining properties. The analysis of the AAL pumping tests is further discussed in Section 7.4 below. Table 6-8 provides a general overview of the permeability values for the various hydrogeological units.

6.9 | Water Balance |
It is assumed that in most enclosed basins, in absence of any major groundwater abstraction, the long-term water balance is in equilibrium with groundwater recharge equal to the groundwater discharge. Groundwater recharge in high desert basins is generally difficult to quantify due to scarcity of precipitation measurements (liquid and solid) and the uncertainties in the soil infiltration and potential sublimation rates, and runoff coefficients. Groundwater recharge was estimated from groundwater inflow into the salar from surrounding sub-basins for which infiltration was calculated through a HEC-HMS model by the DHI Group.
Groundwater discharge in enclosed basins takes place through evaporation as a function of soil type (grainsize/permeability), depth to the phreatic level, water (brine) density and climatic factors. Soil evaporation rates for the Project area were determined as a function of these parameters using evaporation domes and data collection from shallow auger holes in December 2018.
The results of the water balance estimate for the Project area are summarized in Table 6-10. The recharge was estimated at 730 l/s and could be underestimated due to the uncertainties explained above. The discharge for the Project area was estimated at 810 l/s.

Rio Tocomar entering Cauchari from the south and Rio Archibarca from the west are the only two permanent (year-round) surface water features in the Project area. Other surface water flows are intermittent and occur generally during summer months as a result of intense rainfall events.
Rio Tocomar and Rio Archibarca have been monitored on a relatively regular basis by Minera Exar since 2010 and more recently also by Orocobre since 2015. Orocobre has made these monitoring data available, and they are discussed below. Flow measurements for other intermittent surface water features are sporadic and records are not complete.

7. | Exploration |
This section summarizes exploration conducted in support of the Project.
7.1 | Surface Sampling |
In 2009, Geochemical sampling was conducted on 134 brine samples from 105 pits. Results showed that the northern part the salar had the most elevated lithium concentrations.
7.2 | Logging Historical Drillhole Cuttings |
Refer to section 7.4 for details of core logging.
7.3 | Geophysical Exploration |
7.3.1 | Audio Magnetotelluric Survey – 2009 (AMT) |
In 2009 geophysical surveys undertaken by Orocobre in Cauchari consisted of three coincident AMT and gravity lines aimed at mapping the basin geometry and depth.
7.3.1.1 | AMT Data Acquisition |
Audio-frequency MT (AMT) measures temporary variations in the electromagnetic field caused by electrical storms (high frequencies >1 Hz), and the interaction between the solar wind and the terrestrial magnetic field (low frequencies <1 Hz), which allows variations in the electrical subsurface to depths of 2 km or more.
The electrical properties of the subsurface depend on Archie’s Law: Rt = a Rw / Pm where Rt is the measured total resistivity, Rw is the resistivity of the fluid in the rock pores and P is the rock porosity, a and m are constants. Hence, it is possible to infer the subsurface variations in fluid resistivity and porosity, although it is important to note that once again the problem of a non-unique solution always exists.
Data at 250 m spaced stations was acquired using Phoenix Geophysics equipment within a range of 10,000-1 Hz, using up to 7 GPS synchronized receptors. The equipment includes a V8 receptor with 3 electrical channels and 3 magnetic channels which also serves as a radio controller of auxiliary RXU-3E acquisition units. Three magnetic coils of different size and hence frequency was used at each station, and non-polarizable electrodes that improve signal to noise ratios. The natural geomagnetic signal during the acquisition period remained low (the Planetary An Index was <= 5 for 95% of the acquisition time) requiring 18- 20 hours of recording at each station.
Cauchari Lithium Brine Project
SEC Technical Report Summary
All stations were surveyed using differential GPS to allow for subsequent topographic corrections. AMT requires a Remote Station, far from the surveyed area, in a low-level noise location to act as a baseline for the acquired data.
7.3.1.2 | AMT Data processing and modelling |
Processing of the AMT data requires the following stages:
● | Filtering and impedance inversion of each station. |
● | 1D inversion for each station. |
● | Development of a resistivity pseudo-section. |
● | 2D profile inversion (including topographic 3D net). |
The WinGlink software package was used for filtering, inversion, and development of the pseudo-section and eventually the 2D model output.

7.3.1.3 | AMT Model output and interpretation |
The 2D AMT model results for the northern section at Cauchari are presented below in Figure 7-2. The drill hole CAU12DA is located within 1 km of the geophysical profile. In the Cauchari north AMT line the darkest blue on the AMT line is interpreted to represent brine, which extends across the salar between bounding reverse faults which thrust older sediments and unsaturated units over the salar sediments on the margins of the salar basin. This interpretation is supported by TEM (King, 2010b) and electrical soundings (Vazques, 2011) conducted by LAC in the adjacent tenements.

7.3.2 | Gravity Surveys |
7.3.2.1 | Gravity Survey – 2009 |
Gravity techniques measure the local value of acceleration which, after correction, can be used to detect variations in the gravitational field on the earth’s surface which may then be attributed to the density distribution in the subsurface. As different rock types have different densities, it is possible to infer the likely subsurface structure and lithology, although various combinations of thickness and density can produce the same measured density; resulting in multiple possible models for layers in the salar (referred to as non-unique solutions to the gravity data).
Cauchari Lithium Brine Project
SEC Technical Report Summary
7.3.2.2 | Gravity Data Acquisition |
Gravity data was acquired at 200 m spaced stations which were surveyed with high precision GPS equipment. A Scintrex CG-5 gravimeter (the most up-to-date equipment available) was used, and measurements were taken over an average 15-minute period in order to minimize noise. A base station was established with readings taken at the beginning and end of each day’s activities in order to establish and subsequently correct for the effects of instrument drift and barometric pressure changes. The daily base stations were referred to the absolute gravity point PF-90N, close to Salta, where a relative gravity of 2,149.14 mGal was obtained. Since this point is distant from Cauchari, intermediate stations were used to transfer the absolute gravity to Pastos Chicos where a relative gravity base station was established with a value of 1,425.31 mGal.
A differential GPS was used to survey the x, y, and z coordinates of the gravity stations (Trimble 5700). This methodology allows centimeter accuracies with observation times comparable to or less than the corresponding gravity observation. The gravity station position data was recorded using a mobile GPS (Rover). Another GPS (Fixed) at the fixed base station recorded data simultaneously to correct the Rover GPS. The Fixed and Rover GPS units were located within a radius of 10 to 20 km of each other. Both data sets were post-processed to obtain a vertical accuracy of 1 cm.
7.3.2.3 | Gravity Data processing |
In order to arrive at the complete Bouguer anomaly which can be used to interpret the subsurface the following corrections to the acquired data must be made:
● | Tidal correction. |
● | Drift, instrumental height, and ellipsoid corrections. |
● | Free air, latitude, Bouguer and topographic corrections. |
The tidal correction compensates for variations in gravity caused by the sun and moon. Using TIDES software, the acceleration due to gravity for these effects can be determined corresponding to the location and time of measurements. The data acquired in the survey were translated to UTC time to facilitate data handling. The exported data were converted from μGal to mGal and used to correct the acquired data.
Instrument drift was calculated from the difference in gravity measured at the base station. This difference was then linearly distributed with respect to time of each reading and used to correct the acquired data.

Each reading was corrected for the height of the instrument using the following formula:
where rh is the corrected instrument height, rt is the tidal correction, and hi is the observed instrument height. The formula employed to correct variations in gravity associated with the ellipsoidal shape of the earth corresponds to the 1980 model:
where gl is the theoretical gravity in milligals and l is latitude.
The free air anomaly is calculated as:
where gfree air is the correction factor and ∆h refers to the difference in altitude of the station with respect to the base.

Cauchari Lithium Brine Project
SEC Technical Report Summary
To eliminate the effect of the rock masses between the reference level and observation station, the Bouguer correction was employed.
gCB = 0.04191(∆h) ρ (Formula 4)
where gCB is the correction factor, the value ∆h refers to the difference in altitude between the observation point and the base station, and ρ is the mean rock mass density in the area calculated using the graphical Nettleton method to be 2.07 gm cm3.
The topographic correction is used to compensate the effects of the relief in the gravity measurements. It considers the topography at different levels of accuracy and importance, according to its distance from the gravimetric station to correct. Centered areas are considered at the station with radii of 100 m, 2.5 km, and 150 km respectively. The result of applying all corrections is the Bouguer anomaly.
7.3.2.4 | Gravity data modelling |
The Bouguer anomaly can be modeled to represent the subsurface geology. However, any model is non-unique, and it is essential to consider the known geology and rock density. After the gravity survey, drilling was carried out 2011 and density measurements were made on 18 core samples. This information (Table 7-1) was used to remodel the gravity profile across the central part of the salar. The interpretation is provided in Figure 7-1.
Table 7-1 – Bulk rock density values used in the gravity interpretation.

The gravity interpretation extends the asymmetric nature of the Salar de Cauchari towards the south (Figure 7-1), although the maximum basin depth was interpreted to be greater than 450 m along the eastern boundary in the southern gravity line. Recent drilling by the company, with Rotary hole CAU11 completed to 480 m and other holes such as CAU14 to 600 m, suggests that the gravity modelling substantially underestimates the thickness of the salar sediments and the depth to underlying basement. Drilling by neighboring property owner Lithium Americas Corp (LAC) supports this interpretation, with the deepest historical hole drilled by LAC to 650 m (Burga et. al, 2017).

7.3.2.5 | Gravity Survey – 2016 |
In late 2016 additional gravity data was collected on a quasi-grid basis across the NW Sector and SE Sectors of the Cauchari Salar. The work was carried out by staff from the Seismology and Geophysics institute at the University of San Juan using Scintrex CG-3 and CG-5 gravimeters and digital GPS equipment to precisely locate each gravity station. A series of regional gravity points were measured in the surrounding area and a residual bouguer map was generated from the available information. Lines were on a nominal 1 km spacing north- south, with gravity stations measured every 200 m along the lines. The process of gravity data is consistent with the activities described above in the section discussing processing of the earlier acquired geophysical data.
The gravity survey confirmed the geometry of the Cauchari basin is similar to that presented in Figure 7-1, with the deepest part of the basin on the eastern side.
7.3.3 | Time Domain Electromagnetic (TEM) Survey – 2018 |
In 2018 a TEM survey was undertaken in the NW Sector to assist mapping of the brine body. The TEM survey was conducted with a Geonics Protem 20 channel transmitter, with 195 stations read across five lines, using 200 x 200 m loops transmitting at 25 and 2.5 Hz with 100 V output. The receiver was configured to automatically make 3 readings, each with an integration period of 30 seconds. To evaluate the coherency of the data a comparison of the graphical display of the Z component resistivity with time was made on the three recorded measurements. If noise was detected a repeat set of 3 measurements was made.
Further quality control was made when data was downloaded from the Protem device. The data was then presented as profiles, which clearly identified the unsaturated zone, fresh to brackish water, the transition to brine and the brine body itself, as well as basement features on the margins of the survey area, near outcropping rocks. This information has been incorporated into the geological and resource model for the Project, as diamond drilling has provided useful information to validate the TEM profiles.

7.3.4 | Drilling |
Three drilling campaigns have been carried out for the Project since 2011. The first program in 2011 by SAS (Phase I) covered the SE Sector of the Project area; the second and third campaigns (Phases II and III) by AAL covered both the NW and SE Sectors of the Project area. The objectives of the drilling and testing can be broken down into three general categories:
1. | Exploration drilling on a general grid basis to allow the estimation of “in-situ” brine resources. The drilling methods were selected to allow for 1) the collection of continuous cores to prepare “undisturbed” samples from specified depth intervals for laboratory porosity analyses and 2) the collection of depth-representative brine samples at specified intervals. The 2011 campaign included five (5) diamond core holes CAU01 through CAU05 and one rotary hole (CAU06). The Phase II and III programs included 20 diamond core holes (CAU12 through CAU29). Figure 7-7 shows the location of the exploration boreholes. |
2. | Test well installations. The Phase II campaign included five rotary holes (CAU07 through CAU11) which were drilled and completed as test production wells to carry out pumping tests and additional selective brine sampling. Monitoring wells were installed adjacent to these test production wells for use during the pumping tests as part of the Phase III program. |
3. | Pumping tests. Initial short-term (48 hour) pumping tests were carried out on CAU07 through CAU11 during 2017. Two long-term (30-day) pumping tests were carried out on CAU07 and CAU11 as part of the Phase III program. Three nested monitoring wells were completed immediately adjacent to each CAU07 and CAU11 to observe water levels in distinct hydrogeological units throughout the 30-day tests. |
7.3.5 | Exploration Drilling |
Five HQ and NQ core holes (CAU01 through CAU05) were drilled for a total of 721 m by Falcon Drilling using a Longyear 38 trailer mounted rig in 2011. CAU06R was drilled as a rotary hole to 150 m depth. 20 HQ core holes were drilled for a total of 9,376.5 m by Falcon- AGV and Major Drilling in 2017/18. Core recovery averaged 76% and 70% in the 2011 and 2017/18 programs, respectively. Table 7-2 shows the details of the drilling depths that varied from 46.5 m in CAU04D to 619 m in CAU12D. All holes were drilled vertically.
Diamond drilling was carried out in 1.5 m core runs with lexan (plastic) tubes in the core barrel in place of a split triple tube. Core recovery was measured for each run. The retrieved core was subsampled by cutting off the bottom 15 cm of alternating 1.5 m length plastic core tubes (nominal 3 m intervals) for porosity analysis. Thereafter, cores were split, and the lithology was described by the on-site geological team.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Brine samples were collected using a bailer and following protocols developed by Orocobre for resource drilling at the Olaroz Project. Brine samples were taken at 3 m intervals during the 2011 program and at 6 m to 12 m intervals (due to deeper holes) during the 2017/18 program. Up to 3 well volumes of brine were bailed from the hole prior to sampling. The bailed brine volume was adjusted based on the height of the brine column at each sampling depth.
Core drilling was carried out using brackish water from the margins of the salar as drilling fluid. This fluid has a Li concentration of less than 20 mg/l. Fluorescein, an organic tracer dye was added to the drilling fluid to distinguish between drilling fluid and natural formation brine. Detection of this bright red dye in samples provided evidence of contamination from drilling fluid and these samples were discarded.
Brine sample recovery from halite and clay units was low due to the low permeability and brine samples were not obtained in a number of intervals in various holes. Double packer brine sampling equipment was used to obtain check samples from selected depth intervals. On completion of the drilling and sampling, each diamond hole was completed as a monitoring well by the installation of 3-inch diameter schedule slotted PVC.

7.3.6 | Production Well Drilling |
Five test production wells (CAU07 through CAU11) were drilled and completed by Andina Perforaciones using a Speedstar SS-3 table drive rotary rig in 2017. The rotary holes were drilled at a first pass in 7 7/8 –inch diameter and subsequently reamed to 15-inch diameter in the upper part of the hole and to 12- inch diameter in the lower part of the hole. Drilling depths varied between 343 m (CAU07) and 480 m (CAU11). A total of 2,052 m was drilled with the rotary method during which cutting samples were collected at 2 m intervals for geological logging using a hand lens and binocular microscope. Cuttings were stored in chip trays. The holes were completed with 8-inch (upper section) and 6-inch diameter (lower section) blank and screened stainless steel production casing. The completion details of the test wells are provided in Table 7-2. The annulus space was completed with a gravel pack and a cement surface seal. The wells were developed by pumping over a minimum 72-hour period with a submersible pump.
7.3.7 | Pumping Tests |
7.3.7.1 | 48-Hr Pumping Tests |
Preliminary pumping tests were carried out on the five test production wells CAU07 through CAU11 during the Phase II program in 2017. These pumping tests were carried out over a period of 48 hours after the well development was completed. In each well the pump was installed within the upper 8-inch section of the wells. The pumping test in CAU07 (completed in the coarser grained units of the NW Sector) was carried out at a rate of 17 l/s. The test in CAU11 (completed in the deep sand unit of the SE Sector was carried out at a constant rate of 19 l/s. The tests in CAU08, CAU09, and CAU10 (all completed in the finer grained and halite units in the SE Sector) were carried out at a constant rate of 4 l/s.
7.3.7.2 | 30-Day Pumping Tests |
Two long-term (30-day) pumping tests were carried out on CAU07 in the NW Sector and CAU11 in the SE Sector as part of the Phase III program. Three nested monitoring wells were completed immediately adjacent to CAU07 in three distinct hydrogeological units as follows: the upper Archibarca fan material (freshwater aquifer); the intermediate low permeability clay and a third in the lower brine aquifer of the NW Sector. The 30-day CAU7 test started on December 11, 2018, and stopped on January 10, 2019. The average flow during the test was 22 l/s and the observed drawdown in the pumping well stabilized at 40.2m. Brine produced during the pumping test was discharged through a 0.80 km length pipeline into a LAC evaporation pond. Water level recovery was observed over a 15-day period after completion of the pumping cycle. Table 7-3 shows the results of the CAU7 pumping test interpretation.

7.4 | Recommendations |
7.4.1 | NW wellfield area |
● | It is recommended that two additional test production wells are installed in the lower Archibarca unit to verify the lateral continuity of the low permeability units (and/or anisotropy) between the upper freshwater aquifer and the underlying brine unit. Each well site will require the completion of two adjacent monitoring wells with isolated screened intervals in the upper and lower units. Complete 7-day pumping trials in each new test production well. |
● | A minimum of 10 additional mini piezometers are installed at the toe of the Archibarca Fan and new evaporation measurements are undertaken to refine the water balance. |
● | Low flow sampling is carried out in CAU7M350, CAU17D, CAU18D, CAU20D, and 21D at five selected depth intervals to verify previous chemistry analysis. |

8. | Sample Preparation, Analyses And Security |
This section describes the preparation and analyses of samples taken from the Salar de Cauchari.
8.1 | Drilling, Core Sample Collection, Handling and Transportation |
Diamond drilling took place in HQ or NQ sizes with lexan tubes inside the core barrel to facilitate recovery and preparation of sub-samples for laboratory physical parameter analyses. When cores were recovered to surface the lexan tube was pumped from the core barrel using water and a plug separating tube and water. Upon release from the core barrel tight fitting caps were applied to both ends of the lexan tube. The lexan tube was then cleaned, dried, and labeled.
8.2 | QA / QC Procedures |
8.2.1 | Drainable Porosity Sample Preparation, Handling and Security |
The 2011 samples were prepared for drainable porosity testing and brine extraction by the BGS and consisted of a 20 cm sub-section of core cut from the bottom section of each lexan liner. The samples prepared for total porosity testing by the Company’s laboratory in Salta consisted of a 10 cm sub-section of the core. Both sample types were sealed with endcaps and taped. All samples were labelled with the borehole number and depth interval. Each day the porosity samples were transferred to the workshop in the onsite camp where the samples were labelled with a unique sample number. Prior to shipping each sample was wrapped in bubble plastic to prevent disturbance during shipping. A register of samples was compiled at the camp site to control transportation of samples to the Company’s Salta office. Porosity samples prepared from the HQ core collected during the 2017/18 Program followed the same procedures as outlined above.
The following test work has been carried out on the undisturbed core samples:
● | 123 samples were analyzed by the BGS laboratory for total porosity and specific yield from the 5 core holes CAU1 through CAU5 drilled in 2011. 13 samples were rejected on arrival in the BGS due to damage that occurred during the shipping and handling. |
● | 164 samples were analyzed in 2011 by the Company’s Salta laboratory for total porosity. |
● | 292 samples were analyzed by GSA in 2017/18 for drainable porosity and other physical parameters. |
● | 30 samples (subsamples from the 2017/18 GSA samples) were analyzed as QA/QC analyses by Corelabs in Houston TX in 2018, with a further 26 samples analyzed by DBSA. |

8.3 | Sample Shipment and Security |
Brine samples were taken using bailer, packer, and drive point methods. In addition, a second sampling was carried out once drilling was finished using Low Flow Sampling (LFS) equipment inside the 3-inch diameter PVC slotted casing installed in each of the DD boreholes. Prior to bottling, the sample was transferred to a bucket, which had been rinsed with the same brine as the sample. When necessary fine sediment was allowed to settle in the bucket before the brine sample was transferred from the bucket to two 1-liter plastic bottles. The bottles were rinsed with the brine and then filled to the top of the bottle removing any airspace and capped. Bottles were labeled with the borehole number and sample depth with permanent marker pens, and labels were covered with transparent tape, to prevent labels being smudged or removed. Samples with fluorescein contamination were noted at this point and except in specific circumstances these were not sent for laboratory analysis, due to the interpreted sample contamination.
A volume of the same brine as the bottled sample was used to measure the physical parameters: density (with a pycnometer), temperature, pH, Eh and in some samples dissolved oxygen. Details of field parameters were recorded on paper tags, which were stuck to the bottle with transparent tape when completed with sample information.
Samples were transferred from the drill site to the field camp where they were stored in an office out of direct sunlight. Samples with suspended material were filtered to produce a final 150 ml sample for the laboratory. Before being sent to the laboratory the 150 ml bottles of fluid were sealed with tape and labeled with a unique sample ticket number from a printed book of sample tickets. The hole number, depth, date of collection, and physical parameters of each sample number were recorded on the respective pages of the sample ticket book and in a spreadsheet control of samples. Photographs were taken of the original 1-liter sample bottles and the 150 ml bottles of filtered brine to document the relationship of sample numbers, drill holes and depths.
Brine chemistry analyses summary was carried out as follows:
● | 268 brine samples including (QA/QC samples: duplicates, standards, and blanks) were analyzed by Alex Steward Assayers (ASA) in Mendoza Argentina as the primary independent laboratory for the 2011 campaign. |
● | 15 brine samples were analyzed by the University of Antofagasta as the external secondary laboratory for QA/QC analyses during the 2011 campaign. |
● | 1,565 brine samples including (QA/QC samples: duplicates, standards, and blanks) were analyzed by NorLab in Jujuy, Argentina as the primary laboratory for the 2017/18 campaign. |
● | 42 brine samples were analyzed by Alex Steward Assayers (ASA) in Mendoza Argentina as the secondary laboratory for QA/QC analyses during the 2017/18 campaign. |

8.4 | Core Handling Procedures - Brine Analysis and Quality Control Results |
8.4.1 | Analytical Methods |
Alex Stewart Argentina in Jujuy, Argentina (NorLab) was selected as the primary laboratory to conduct the assaying of the brine samples collected as part of the 2017/18 drilling program. This laboratory is ISO 9001 accredited and operates according to Alex Stewart Group standards consistent with ISO 17025 methods at other laboratories.
Alex Stewart Argentina in Mendoza, Argentina (ASAMen) was used for the analysis of external check samples during the 2017/18 drilling campaign and as primary laboratory during the 2011 drilling campaign. The laboratory of the University of Antofagasta in northern Chile was also used for external check samples during the 2017/18 and 2011 campaigns. This laboratory is not ISO certified, but it is specialized in the chemical analysis of brines and inorganic salts, with extensive experience in this field since the 1980s, when the main development studies of the Salar de Atacama were begun. Other clients include SQM, FMC, LAC and Orocobre.
Table 8-1 lists the basic suite of analyses requested from the laboratories. The labs used the same analytical methods based on the Standard Methods for the Examination of Water and Wastewater, published by American Public Health Association (APHA) and the American Water Works Association (AWWA), 21st edition, 2005, Washington DC.

8.4.2 | Analytical Quality Control – 2011 Program |
A full QA/QC program for s accuracy, precision and potential contamination of the entire brine sampling and analytical process was implemented. Accuracy, the closeness of measurements to the “true” or accepted value, was monitored by the insertion of standards, or reference samples, and by check analysis at an independent secondary laboratory.
Precision of the sampling and analytical program, which is the ability to consistently reproduce a measurement in similar conditions, was monitored by submitting blind field duplicates to the primary laboratory. Contamination, the transference of material from one sample to another, was measured by inserting blank samples into the sample stream at site.
Blanks were barren samples on which the presence of the main elements undergoing analysis has been confirmed to be below the detection limit. The results of the analyses of the standards are summarized in Table 8-2. The analyses showed little systematic drift in the results relative to the standard values over the period analyzed. Results are generally within 10% of stated standard values, with a small number of exceptions for each element. However, boron values were consistently below the standard value for standards 4G, 5G and SG2.

Checks analyses were conducted at ASAMen on 5% of the primary brine samples consisting of 42 external duplicate samples. In addition, some blanks and standard control samples were inserted to monitor accuracy and potential laboratory bias. No bias was found in relation to the blanks and standard control samples. Table 8-5 summarizes the results of the duplicate analyses and lists the statistics, number of samples exceeding the acceptable failure criteria of a 5% bias between duplicates. An important bias for the ASAMen laboratory was found for medium to high potassium concentrations.

In addition to evaluation of standards, field duplicates and blanks, the ionic balances (the difference between the sum of the cations and the anions) were reviewed to evaluate the quality of the laboratory analyses. Balances are generally considered to be acceptable if the difference is <5% and were generally <1%. No samples were rejected as having > 5% balances. The results of standard duplicate and blank samples analyses are considered to be adequate and appropriate for use in the resource estimation described herein.

8.4.5 | Accuracy (Standards) |
The Project has two groups of standards. The first group was inserted in lot 1 to 39, and the second group was inserted from lot 40 to 71. As a result of inconsistency in the composition of the first standard group in the last few batches in which they were used, a second group of standards was prepared and used throughout the remainder of the drilling and sampling program. The deterioration of the first standard group was detected in batch 34, 35 and then reanalyzed and confirmed in batch 36, so the standard samples of these batches (34, 35 and 36) were discarded for this analysis.
The first group of standards consisted of six different standards of which only two were submitted to three inter-laboratories tests (RRA): standards STD-4G and STD-7G. Only these two standards were used for the analysis.
The second group of standards was prepared from a locally available brine source provided by the Sales de Jujuy laboratory with approximate Li concentrations of 900 mg/l and 500 mg/l. In order to have representative standards and enough quantities for the continuity of the drilling program, a series of dilutions were carried out under controlled conditions to yield three final standards with approximate lithium concentrations of 500 mg/l, 400 mg/l and 200 mg/l and named (STD-500, STD-400, and STD-200). These standards were subjected to a round robin analysis (RRA) of pre-selected laboratories (NorLab, ASA Mendoza, SGS in Argentina and Universidad Católica del Norte and Universidad de Antofagasta in Chile).
Control and accuracy charts were prepared for each standard. The values reported for the standards were plotted in a time sequence, the lines corresponding to:
● | B (Best Value). |
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | 1.05 * BV (Best Value) + CI (Confidence Interval). |
● | 0.95 * BV (Best Value) - CI (Confidence Interval). |
● | AV (Average) ± 2 *SD (standard deviation). |
The Best Value (BV) and the Confidence Interval (CI) at 95 percent were calculated for the results of the different laboratories; the average (AV) and the standard deviation (SD) were calculated with the results of the analysis of the inserted standards. As a rule, the standards that fall within the limits defined by the mean ± two standard deviations are accepted, values that fall beyond these limits are qualified as outliers. The analytical bias Sa is calculated by the following formula.
Sa (%) = (AV/BV) – 1
Where AV represents the average of the values obtained after excluding the erratic values and BV represents the best value of the standard for the element in question. The bias is considered acceptable if its absolute value is less than 5%, questionable if it is between 5% and 10%, and unacceptable when it exceeds 10%.
The general bias of each element is calculated with the following formula:
Sg (%) = SRL – 1
Where SRL is the slope of the linear regression of the plotted line of the Average versus the Best Value of each standard and element. A summary of the characteristics and performance of the standards of the first group are presented in Table 8-7 and of the second group in Table 8-8. For all the elements considered of the standards analyzed, good accuracy is observed (Bias <5%).

8.4.6 | Contamination (Blanks) |
A total of 106 blanks were inserted to analyze for potential sample contamination. Some batches showed values of Ca and Na that exceeded the quantification limit. Nevertheless, the correlation between these samples and their respective consecutives allows to establish that there is no clear analytical contamination but a variation in the source of distilled water used in the preparation of the blanks.
8.5 | Specific Gravity Measurements, Drainable Porosity Analysis and Quality Control Results |
8.5.1 | British Geological Survey - 2011 |
The British Geological Survey (BGS) was used during the 2011 campaign to analyze drainable porosity. Specific yield (or drainable porosity) is defined as the volume of water released from storage by an unconfined aquifer per unit surface area of aquifer per unit decline of the water table. Bear (1979) relates specific yield to total porosity as follows: n = Sy + Sr, where Sr is specific retention.
The BGS determines drainable porosity using a centrifugation technique where samples are saturated with simulated formation brine and weighed. They are then placed in a low speed refrigerated centrifuge with swing out rotor cups and centrifuged at 1,200 rpm for two hours and afterwards weighted a second time. A centrifuge speed is selected to produce suction on the samples equivalent to 3.430 mm H2O. This suction is chosen as it had previously been used by Lovelock (1972) and Lawrence (1977) and taken to be characteristic of gravitational drainage.
8.5.2 | Geosystems Analyses – 2017/18 |
Geosystems Analyses (GSA) was selected as the main laboratory for the Phase II and III drainable porosity (Sy) and other physical parameter analyses. GSA utilized the Rapid Brine Release method (Yao et al., 2018) to measure drainable porosity and the total porosity. The Rapid Brine Release (RBR) method is based on the moisture retention characteristics (MRC) method for direct measurement of total porosity (Pt, MOSA Part 4 Ch. 2, 2.3.2.1), specific retention (Sr, MOSA Part 4 Ch3, 3.3.3.5), and specific yield (Sy, Cassel and Nielson, 1986). A simplified Tempe cell design (Modified ASTM D6836-16) was used to test the core samples. Brine release was measured at 120 mbar and 330 mbar of pressure for reference (Nwankwor et al., 1984, Cassel and Nielsen, 1986).

In addition to drainable porosity, bulk density, particle size analyses and specific gravity were determined on selected core samples. Table 8-9 provides an overview of the test work carried out by GSA. Figure 8-2 shows the results of the test work by lithology type.

8.5.3 | Drainable Porosity Quality Control - 2018 Program |
For quality control, a subset of paired samples representative of the range in lithology types were selected by AAL and GSA for testing using the Relative Brine Release Capacity (RBRC, Stormont et. al., 2011) method by DBSA, or the Centrifuge Moisture Equivalent of Soils (Centrifuge, ASTM D 6836-16) method by Core Laboratories (Houston, TX). Table 8-10 shows a summary of the comparison by laboratory for each method derived for paired core samples using the RBR, RBRC, and Centrifuge methods.
Correlations between GSA and external laboratory measured values are provided in Figure 8-2. There is a lower correlation between the specific yield data (R2 = 0.44). Correlation was slightly higher (R2 = 0.45) between Sy (RBRC and Centrifuge) and drainable porosity at 120 mbar (RBR, Figure 8-3). Most of the samples tested for Sy fall below the 1:1 line, indicating that GSA measured Sy values were often higher than external laboratory measured Sy values, particularly those from Core Laboratories. Differences are likely attributable to testing equilibration time and testing method, with GSA testing the samples for a longer period than the DBSA laboratory using the RBRC method.

This section describes the processing of extracted brine into saleable products. Related test work, assumptions and expected recoveries are further described.
10.1 | Initial Characterization and Scoping Studies |
The brines from Salar de Cauchari are solutions nearly saturated in sodium chloride with an average concentration of total dissolved solids (TDS) of 290 g/l. The average density is 1.19 g/cm3. Components present in the Cauchari brine are K+, Li+, Mg++, Ca++, Na+, Cl–, SO4 2–, and borates. Table 10-1 presents a summary of the Cauchari 2019 exploration sample brine chemistry.
Table 10-1 – Brine chemistry summaries for Cauchari and for Olaroz
Table 10-1 also presents a summary of the Olaroz 2011 exploration brine chemistry. When the chemical characteristics of the Cauchari brine were established, it became clear that they were very similar to the Olaroz brine. The Olaroz salar is 20 km north of the Cauchari salar and the climatic conditions around the two salars are similar. The variance for the Mg/Li and for the Li/ SO4 ratios for both brines are low enough to state that Cauchari brine could be processed using similar processing technology to that applied in the Olaroz production facility, which has been successfully applied to produce lithium carbonate in the Orocobre facilities.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Using the Cauchari and Olaroz brine compositions, Janecke phase diagrams were produced to show the evaporation paths for the two brines, under winter and summer conditions. It can be said that the precipitation is dependent on seasonal temperature and as such, there is Glauber salt (Na2SO4•10H2O) precipitating during cold months (winter season) and glaserite salts (Na2SO4•3K2SO4) precipitating along with gypsum salts during hot months (summer season). Saturation in sylvite (KCl) will occur at about 0.4% (5,300 mg/l) of lithium. Figure 10-1 presents the winter diagram and Figure 10-2 presents the summer diagram.

Initial assessment of the Olaroz brine chemistry in 2008 indicated that it had a low magnesium to lithium ratio, moderate levels of sulphate and was suitable for application of the ‘Silver Peak’ method used at the world’s first lithium brine treatment operation in Nevada, USA since the mid 1960’s. However, the ‘Silver Peak’ process, although generally applicable to the Olaroz brine chemistry, required modification to suit the differences in brine chemistry and the different climatic conditions at the Olaroz Project. The process route also required some enhancement to produce a lithium product to meet the more demanding battery grade specifications.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The process development program sequentially defined the performance of each stage in the process, resulting in a flow sheet capable of producing battery grade lithium carbonate. Test work has been undertaken at SDJ’s facilities at the Olaroz Project site and at commercial and university laboratories. The process development program resulted in a process route incorporating a number of proprietary innovations. Early work focused on evaporation rate testing to understand the phase chemistry of the brine during a twelve-month weather cycle, this followed by lime addition test work to remove magnesium. Subsequently, the focus of the Olaroz Project test work moved to the removal of boron by multi-stage solvent extraction processing, and then on to the final stage of lithium carbonate purification.
Lithium is present at concentrations that are economic but are low in comparison to the other salts in the brine. Before final purification the other salts must be selectively rejected, and this is done primarily by evaporation, causing the salt concentrations to increase beyond their solubility limits, and by simple and well-established methods of chemical treatment. Based on test work and phase chemistry, over 70% of the lithium was modelled to be recovered in this process to a high specification product, with the majority of the lithium losses incurred by inclusion of brine in the pores of the solid salts formed during the evaporation process.
There is nothing to suggest that if the Cauchari brine followed the same test work path, the results would not be similar to those of Olaroz. The most significant aspect is that the Olaroz test work has been translated into a successful operation. Applying Olaroz operating experience, particularly process lessons learned from the operation, is more valuable than any test work. This is because more process data is generated than is possible with test work and there are people available with operating experience who can assist with the Cauchari process design.
10.2 | Metallurgical test-work program |
10.2.1 | Overview |
The Olaroz brine underwent laboratory and pilot scale test work during the period 2008 to 2011 to establish the process design basis for the
original Orocobre operation which started up in 2015.
For all the Olaroz experimental work, well FD-16B was used which was drilled during the 2008 drilling program. Analysis of the brine chemistry of the 2010 drilling data and 2011 resource estimate showed FD-16B brine to be representative of the Olaroz
resource.
The Olaroz Salar brine is located at the border of the Janecke glaserite (Na2SO4.3K2SO4) field and the ternadite (Na2SO4) fields. Low ambient temperatures at the Olaroz Salar will cause the crystallization of sulphate as glauber-salt (Na2SO4.10H20) in
the evaporation ponds (refer to figures 10-1 and 10-2). The Cauchari brine chemistry shows similar properties, as well as there being low ambient temperatures at the Cauchari Salar.
The low Mg/Li ratio of the Olaroz brine makes magnesium removal with slaked lime a feasible process step. The Cauchari brine has the same Mg/Li ratio, which means slaked lime addition for magnesium removal can also be applied. The Olaroz brine has a
high sulphate content (high SO4/Mg); hence sodium and potassium sulphate salts are likely to crystallize. As it has a SO4/Mg ratio higher than 4, there is also enough sulphate available in the brine to recipitate the calcium liberated during the
formation of magnesium hydroxide as gypsum. The Cauchari brine also has a high sulphate content and a SO4/Mg ratio higher than 4.
The only disadvantage of the high sulphate level is that it tends to lock up potassium as glaserite and at higher concentrations of lithium, causing lithium losses as lithium schoenite.
10.2.2 | Solar evaporation testing |
The evaporation of water from the solar evaporation ponds is a critical factor in the processing of the brines. The evaporation information was
coherent in that the pilot scale pond testing on saturated Olaroz brine provided an annual rate of 1733 mm. This is conservative in the context of the test results of 3,900 mm per year on water and 2600 mm per year on unsaturated brine.
The actual Olaroz ponds area was designed based on 1,300 mm of annual evaporation [3.6 mm/day]. This is a reasonable base line in the context of brine activity factors that range from 75 – 80% depending on saturation levels, and industrial scaling
factors of 75% applied to small pond data to predict large pond evaporation rates. This also allows a generous margin to compensate for any unusually high rainfall event.
The most relevant and reliable information was provided by the data gathered from the large number of open evaporation test ponds operating in sequence on the Olaroz salar. The weather variables needed to be defined to assist with assessing the
potential for variance in the pilot plant data.
Evaporation is driven by solar radiation, ambient temperatures, wind impact and humidity, and must consider variable rainfall. The average annual temperature at the Olaroz Project site is approximately 7° C, with extremes of 30º C and -15º C. The
coldest months with temperatures below zero correspond to May through August. Solar radiation is the most important factor in evaporation. The rainfall in the operating years 2015 – 2021 was often significantly higher than the early design basis
reflects. This contributed to reduced Li concentration in plant feed and so impacted Olaroz production projections.
The Cauchari salar is 20 km south of the Olaroz salar and the two salars are at the same altitude, which means the climatic conditions are similar. Therefore, the experience gained in evaporation pond design and operation at the Olaroz operation can be
applied to the Cauchari project.
10.3 | Metallurgical results |
10.3.1 |
Crystallized Salts |
In all the ponds it is mainly sodium chloride (NaCl > 94%) that is crystallized. Other salts that crystallize are glauber salt (Na2SO4.10H20: 2-6%) and calcium sulphate (CaSO4.2H20: 1%). In the most concentrated ponds halite and silvite (KCl) crystallize, with minor concentrations of glaserite (Na2SO4.3K2SO4) and borate salts. Under these alkaline conditions the boron is precipitated as sodium and calcium borate [Na2B4O7 and CaB4O7], and to assist in the final lithium purification process this precipitation may be encouraged by addition of calcium chloride. The optimal lithium concentration for the recovery plant was defined by the loss of lithium at concentrations greater than ~0.7% by precipitation of lithium as schoenite [Li2SO4.K2SO4].
Given the similarity between the brine chemistry of the Olaroz salar and that of the Cauchari salar, the nature of the crystallised salts at the Olaroz evaporation ponds will be similar for the Cauchari project.

10.3.2 | Liming test work |
Initially Allkem was using hydrated lime (Ca(OH)2) from a provider located near Jujuy for its Olaroz experiments. This was replaced by active or burnt lime (CaO) from the same provider, with the advantage of reducing product and transportation costs. At pilot scale the lime reacted very well and completely fulfilled the process requirements. Magnesium reacts instantaneously with the lime. Subsequently the liberated calcium starts to react with the available sulphate and some boron reacts early with calcium from the liberated lime.
Given that both the Olaroz and Cauchari brines have high sulphate concentrations and SO4/Mg ratios higher than 4, the application of liming for magnesium removal would be equally applicable to the Cauchari brine.
10.3.3 | Lithium carbonate process |
The Olaroz pilot plant was operated successfully from the 3rd Quarter of 2010, producing technical grade lithium carbonate. At the beginning of 2011 the pilot plant testing process included an additional purification step to achieve battery grade lithium carbonate.
The lithium carbonate process used by Allkem in their Olaroz plant is well proven and has been operating for several years. This process can be applied directly to the Cauchari project, given the similarity between the Cauchari and Olaroz brines.
10.3.4 | Analytical quality control |
Standardized quality control procedures were adopted and verified for the analysis of the various samples emerging from the Olaroz test work program.
These analyses are complicated since the solutions have a high concentration of ions generating interference in the measurements with the analytical equipment. Only a limited number of laboratories have the experience to analyze brines and those laboratories were selected to do Allkem´s quality control.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The samples from the Olaroz Salar were analyzed by Alex Stewart Assayers [ASA] of Mendoza, Argentina, who have extensive experience analyzing lithium bearing brines. The Alex Stewart laboratory is accredited to ISO 9001 and operates according to the Alex Stewart Group (AS) standards consistent with ISO 17025 methods at other laboratories.
Duplicate process samples were sent to:
● | University of Antofagasta (UA), Chile. |
● | ALS-Environment (ALS) laboratory located in Antofagasta, Chile, which is ISO 17025 and ISO 9001:2000 accredited. |
Both the University and the ALS laboratory have a long history in brine analysis. However, the university is not certified.
Physical parameters, such as pH, conductivity, density, and total dissolved solids are determined directly upon brine subsamples. Determination of lithium, potassium, calcium, sodium, and magnesium is achieved by fixed dilution of filtered samples and direct aspiration into atomic absorption or inductively coupled plasma analysis systems.
In summary:
● | ASA analyses show acceptable accuracy and precision with an acceptable anion-cation balance. |
● | Check samples analyzed at ALS Environment displayed acceptable accuracy and precision, with a high degree of correlation with ASA analyses, but the inorganic analytes (Li, K and Mg) are biased higher than corresponding analyses at ASA. |
● | Check samples analyzed at the University of Antofagasta displayed acceptable accuracy and precision, with a high degree of correlation with ASA analyses, but the inorganic analytes (Li, K and Mg) are also biased higher than corresponding analyses at ASA. |
● | The lower bias observed in the ALS and UA data is most likely due to calibration differences between the ICP and AA instruments used to analyze the samples. |
The quality control systems are well designed and under continuous improvement. Data analysis of the QA results produced by the laboratories is considered to have sufficient accuracy for the purposes of process design. The improved performance of the principal laboratory, ASA, as shown by the improvement in ionic balance over time and the reproducibility of the analytical results is noteworthy and shows the benefit of a close working constructive relationship.
10.4 | Metallurgical performance predictions – QP commentary |
To date no actual metallurgical test work has been conducted on the Cauchari brine. The reason for this is because for the Cauchari project PEA in 2018, it was decided that the Cauchari process design could be based on the Olaroz process design, especially given that the Orocobre lithium carbonate operation was already producing lithium carbonate at the time. This decision can be supported for a number of reasons, and these will be discussed below.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The chemistry of the Cauchari brine is well understood due to extensive sampling and analysis that was carried out to support the Cauchari mineral resource estimate. The Olaroz brine chemistry is also well understood and when a comparison is made between Cauchari and Olaroz, their brine chemistries are similar (refer to Table 10-1). The significance of this is best presented using Janecke phase diagrams (refer to Figure 10-1 and Figure 10-2). These show the similarity in the crystallization of salts under evaporation conditions during winter and summer. It is the opinion of the QP that the brine chemistry data and neighbouring Olaroz metallurgical data referenced herein is adequate for the purposes of process design and recovery estimation.
The design of evaporation ponds is primarily based on brine chemistry and climatic conditions. The Cauchari salar is 20 km south of the Olaroz salar and the two salars are at the same altitude, which means their climatic conditions are similar. Therefore, the design of the Cauchari evaporation ponds can be confidently based on the Olaroz evaporation ponds. This is further supported because the Olaroz evaporation ponds have been in operation for 8 years, allowing the accumulation of extensive design and operating data.
The Olaroz lithium carbonate plant was commissioned in 2015. Initially there were a number of problems which were overcome during an extended ramp-up period. A great deal of information relating to production performance and subsequent efficiency improvements has been gained since 2015.
The knowledge and experience gained by Allkem from the first Olaroz plant has resulted in the design, construction, and commissioning of a second Olaroz plant, with an optimized process design and a greater capacity. This second plant is currently in ramp-up.
Allkem’s intention is to base the process design of the Cauchari process plant on its experience derived from the design of both the second Olaroz process plant and its Sal de Vida project. Given all the test work, operating experience, and process optimization behind the second Olaroz plant and its Sal de Vida project, it is reasonable to base the process design of the Cauchari plant on the aforementioned works. The process design basis is adequate for the purposes of this prefeasibility study. Therefore, it is the opinion of the responsible QP that it is reasonable to base the process design of the Cauchari plant on the second Olaroz plant.
In terms of a forecast final lithium recovery, a figure of 66% can be used since this is based on the current Olaroz operating experience. During the Cauchari feasibility study it would be advisable to construct some pilot evaporation ponds at the Cauchari site to generate a lithium carbonate plant feed brine for testing Allkem’s piloting facilities at its Sal De Vida project. This brine could then be tested by the main equipment vendors which were used for the second Olaroz plant. The results of this test work would be used for process design fine tuning where necessary.

11. Mineral Resource Estimates
This section describes the development and current estimate of the mineral resource.
11.1 | Data Used for Brine Resource Estimation. |
The essential elements of a brine resource determination for a salar are:
● | Definition of the aquifer geometry. |
● | Determination of the drainable porosity or specific yield (Sy). |
● | Determination of the concentration of the elements of interest. |
Resources may be defined as the product of the first three parameters. Aquifer geometry is a function of both the shape of the aquifer, the internal structure, and the boundary conditions (brine / freshwater interface). Aquifer geometry and boundary conditions can be established by drilling and geophysical methods. Hydrogeological analyses are required to establish catchment characteristics such as surface and groundwater inflows, evaporation rates, water chemistry and other factors potentially affecting the brine reservoir volume and composition in-situ. Drilling is required to obtain samples to estimate the salar lithology, specific yield, and grade variations both laterally and vertically.
11.2 | Resource Model Domain and Geometry |
The Cauchari resource model domain covers an area of 117.7 km2 and is limited to the Cauchari JV Project area and further constrained by the following factors:
● | The top of the model coincides with the brine level in the salar as measured in a number of monitoring wells and further interpreted by TEM and SEV geophysical profiles. |
● | The lateral boundaries of the model domain are limited to the area of the Cauchari tenements where they flank the neighboring LAC concessions and by the brine / freshwater interface along the eastern and western limits of the salar as interpreted from boreholes information and TEM and SEV profiles. |
● | The bottom of the model coincides with a surface created from the bottom of the boreholes. Locally, a deeper resource volume has been defined in the Lower Sand as defined by boreholes CAU11R, CAU12DA, CAU13DA and CAU19D. |
The resource model has been divided into three domains to account for the different data availability, geological knowledge, and sample support. The domains are shown in Figure 11-1 and are described as follow:
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | Transition Domain: Accounts for five percent of the total resources and is defined as the volume in the upper part of the salar that includes fresher water and transition into brine. The lithium concentrations in the transition zone increase with depth. The number of brine samples in the transition domain is low because the surface casing installations for the exploration boreholes (mostly in the transition domain) was generally carried out using rotary mud drilling that is not suitable for reliable brine sample collection. A regression approach was adapted to estimate the lithium concentrations within this domain due to the good correlation with depth and the lack of samples. |
● | Main Domain: Accounts for 83% of the total resources and has normal and reliable sample data obtained during the drilling. A kriging approach was selected for this domain due to the number of samples available. |
● | Secondary Data Domain: Accounts for 12% of the total resources and its lithium content was defined mostly by brine chemistry analysis on samples derived during pumping tests on CAU8, CAU9, CAU10, and CAU11. An inverse distance approach was selected because of the amount of information available. |
Figure 11-1 – Schematic showing the block model domains.
11.3 | Specific Yield |
Specific yield is defined as the volume of water released from storage by an unconfined aquifer per unit surface area of aquifer per unit decline of the water table.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The specific yield values used to develop the resources model are based on analyses of 301 undisturbed valid samples from diamond drill core by GSA, Core Laboratories, and DBSA as discussed in Section 8. Figure 11-2 shows the normal distribution of the specific yield grouped by lithology.
Figure 11-2 – Normal probability plot of Sy grouped by lithology.
A cell de-clustering approach was used to account for spatial sample density. The de-clustered average was assigned to each geological unit. Table 11-1 shows the general statistics and the de-clustered average for each geological unit.

11.4 | Brine Concentration |
The distributions of lithium and potassium concentrations in the model domain are based on a total of 546 brine analyses (not including QA/QC analyses and rejected samples) as discussed in Chapter 6. Table 6-4 shows a summary of the brine chemical composition.
11.5 | Resource Estimate Methodology, Assumptions and Parameters |
11.5.1 | Overview |
The Stanford Geostatistical Modeling Software (SGeMS) was used for the Cauchari JV brine resource estimation. SGeMS has been used in the past for the estimation of brine resources in other areas of the Central Andes. Geostatistics is a branch of statistics specifically developed to estimate ore grades for mining operations from spatiotemporal datasets. Geostatistics goes far beyond simple interpolation methods such as nearest neighbor or inverse distance as it accounts for the spatial correlation and continuity of geological properties typically observed in the field. Based on this, the following steps were carried out to estimate the lithium and potassium resources.
● | The block model geometry was adapted to represent the geological model as described in Section 6.2 with an appropriate block size (x=100 m, y=100 m, z=1 m). |
● | Generation of histograms, probability plots and box plots were conducted for the Exploratory Data Analysis (EDA) for lithium and potassium. |
● | Calculation of the experimental variograms with their respective variogram models for lithium and potassium in three orthogonal directions. |
● | Definition of the random function model and selection of the kriging method. |
● | Interpolation of lithium and potassium for each block in mg/L using ordinary kriging with the variogram models shown in Figure 11-11 and Figure 11-12. |
● | Calculation of total resources using the de-clustered porosity average value for each geological unit, based on the boreholes data. Each geological unit will represent a particular porosity value as shown in Table 11-1. The total resources are shown in Table 11-7. |

SEC Technical Report Summary
11.5.2 | Exploratory Data Analysis |
The Exploratory Data Analysis (EDA) of lithium (Li) and potassium (K) concentrations consisted of a univariate statistical description using histograms, probability plots and box plots, and a spatial description based on data posting and trend analysis. This information is used to define the random function models and the type of kriging method.
Exploratory data results show significant differences in both the statistical properties of the concentration of ions and the patterns of spatial continuity across the different lithological units defined in the study area. To illustrate this, Figure 11-3 and Figure 11-4 show the box- plot of Li and K, respectively. The boxplots depict the quartiles (the second quartile is the median) as well as the minimum and maximum values of the data analyzed separately by lithological units. In addition, Table 11-2 and Table 11-3 summarize the main univariate statistics of Li and K for the different lithological units.
Li in the Archibarca unit renders less variability than the Halite and West Fan units, and that the mean value of the West Fan is significantly smaller (more than 100 mg/l) than that of the Archibarca unit. Based on this, data within each lithological unit is treated as a separate population. The spatial patterns of Li and K in the different lithological units are also significantly different, suggesting the existence of different statistical populations. This is shown in the next section.

SEC Technical Report Summary
11.5.3 | Variography |
The spatial variability of Li and K concentrations were characterized by the semi-variogram, γ(h). The semi-variogram is a function that measures the variability between pairs of variables separated by a distance h. Very often, the correlation between two variables separated by a certain distance disappears when |h| becomes too large. At this instant, γ(h) approaches a constant value. The distance beyond which γ(h) can be considered to be a constant value is known as the range, which represents the transition of the variable to the state of negligible correlation. Experimental semi-variograms obtained along multiple directions revealed that the random function model of the selected ions can be characterized with an axisymmetric random function model; and symmetric semi-variogram with respect to the z-direction. This type of correlation function model is typically observed in sedimentary geological formations such as an evaporitic system.
11.5.3.1 | Variogram Models of Potassium |
The experimental semi-variograms of K or the different units were fitted with a theoretical model consisting of two correlation structures, i.e., the combination of an exponential model with a Gaussian model. This composite structure is necessary in this case to properly represent the small-scale correlation observed along the z-direction compared to a larger correlation observed in the xy plane directions.
Clay-Halite
yK(h) = 9 × 105 + 105 yExp(ax = ay = 3300, az 60)
+ 8 × 105 yGauss(ax = ay = 3300, az = 300)
Archibarca
yK(h) = 80800 yExp(ax = ay = 4320, az = 20)
+ 140000 yGauss(ax = ay = 4320 az = 350)
West Fan
yK(h) = 2 × 105 yExp(ax = ay = 3300, az 60)
+1.8 × 106 yGauss(ax = ay = 12000, az = 580)
The semi-variogram is expressed in units of mg2/L2, and the range in units of meters. Thus, the correlation structure in the xy plane has a range between 3,300 m and 4,320 m, whereas the correlation structure in the z-direction has a range between 300 m and 580 m. This means that overall, the system is stratified with lenses that extend laterally several kilometers but with limited thickness of few hundreds of meters. The variogram models shown below were fitted to experimental semi-variograms. Only the semi-variogram point estimates with sufficient pair samples were considered. The experimental variograms of lithium and potassium are shown in the following figures with their respective variogram models.

SEC Technical Report Summary
11.5.3.2 | Variogram Models of Lithium |
The experimental semi-variograms were fitted with a theoretical model consisting of only one correlation structure and a nugget coefficient. The experimental variograms for Li with their respective variogram models is shown in the following figures.
Clay-Halite
yLi(h) = 9000 + 18000ysph(ax = ay = 3835, az = 150)
Archibarca
yLi(h) = 2800yExp(ax = ay = 4320, az = 40)
West Fan
yLi(h) = 3000yExp(ax = ay = 5800, az = 50)
The semi-variogram is expressed in units of mg2/L2, and the range in units of meters. In this case, the correlation structure in the xy plane has a range that varies between 3,835 m and 5,800 m, whereas the correlation structure in the z-direction has one structure with a range that oscillates between 40 m and 150 m. Results show that Li is more stratified than K with similar spatial continuity in the xy plane.

10 | 70 | 0 | 90 | 500 | 89 |
11.5.4 | Kriging Methods and Random Function Models |
The estimation procedure follows the method known as ‘kriging within strata’ (KWS). The estimation within each unit is performed with the data associated with that unit and the corresponding variogram model. In some units, the semi-variogram is poorly estimated because the number of data pairs is insufficient. This is the case with Lower Sand and East Fan. In those cases, the proportional effect correction suggested by Journel and Huijbregts (1978) is used to estimate the variogram.
The results of the EDA indicate that even though the structure of heterogeneity (random function model) is different for each unit, ordinary kriging is an appropriate technique for the estimation of Li and K concentrations in each unit. The ordinary kriging method is the most commonly used kriging method. It assumes that the mean is an unknown constant dictated by neighborhood data. Essentially, ordinary kriging re-estimates, at each estimation location, the mean value by only using the data within the search neighborhood. Hence, ordinary kriging can represent a random function with varying mean but stationary variogram. As previously, in accordance with this random function model, all experimental variograms were properly fitted with a combination of stationary theoretical variograms characterized by a well-defined sill. Figure 11-11 and Figure 11-12 show the results from the kriging estimation.

11.6.1.1 | Validation |
To validate the accuracy of our estimation models, a comprehensive series of checks was conducted. These checks encompassed various techniques, including the comparison of univariate statistics, visual inspections, swath plots, and block comparison analyses.
Univariate statistics were utilized to assess the presence of any global estimation bias. Comparisons between the statistics of the sample averages, Nearest Neighbor (NN), and Ordinary Kriging (OK) were performed. Remarkably, the percentage difference between NN and OK stood at a mere 0.17%, indicating a high degree of similarity between the two methods. Table 11-5 summarizes the univariate statistics comparison.

Median | 542.74 | 500.69 | 484.78 | 15.92 | 2.93% |
A block comparison analysis was conducted. In this analysis, a block size of 2,000x2,000x50 meters was used, resulting in an acceptable R-squared value of 0.74. This indicates a good level of agreement between the estimated and observed values within the blocks. Figure 11-14 showcases the block comparisons between Ordinary Kriging estimates and the sample data, allowing for visual assessment of the agreement and accuracy of the estimation model.

Visual inspections were carried out by overlaying the estimated values onto plans and sections containing sample data. This enabled a meticulous examination of the estimated values in relation to the sample locations, helping to identify any discrepancies or spatial bias. Additionally, swath plots were generated in the north, south, and vertical directions to detect potential spatial bias. These plots revealed an acceptable performance overall, with a conservative estimation tendency observed to mitigate regions of very high concentration values. Figure 11-15 presents the swath plots in the north, south, and vertical directions, illustrating the spatial distribution of concentration values.

11.7 | Mineral Resource Classification |
This sub-section contains forward-looking information related to Mineral Resource estimates for Cauchari Project.
11.7.1 | Inferred Mineral Resource |
An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
An Inferred Mineral Resource is based on limited information and sampling gathered through appropriate sampling techniques from locations such as outcrops, trenches, pits, workings, and drill holes. Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash flow models of developed mines. Inferred Mineral Resources can only be used in economic studies as provided under S-K §229.1302 TRS disclosure.
There may be circumstances, where appropriate sampling, testing, and other measurements are sufficient to demonstrate data integrity, geological and grade/quality continuity of a Measured or Indicated Mineral Resource, however, quality assurance and quality control, or other information may not meet all industry norms for the disclosure of an Indicated or Measured Mineral Resource. Under these circumstances, it may be reasonable for the Qualified Person to report an Inferred Mineral Resource if the Qualified Person has taken steps to verify the information meets the requirements of an Inferred Mineral Resource.
11.7.2 | Indicated Mineral Resource |
An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.
Mineralization may be classified as an Indicated Mineral Resource by the Qualified Person when the nature, quality, quantity, and distribution of data are such as to allow confident interpretation of the geological framework and to reasonably assume the continuity of mineralization. The Qualified Person must recognize the importance of the Indicated Mineral Resource category to the advancement of the feasibility of the Project. An Indicated Mineral Resource estimate is of sufficient quality to support a Pre-Feasibility Study which can serve as the basis for major development decisions.
11.7.3 | Measured Mineral Resource |
A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.
Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.
Mineralization or other natural material of economic interest may be classified as a Measured Mineral Resource by the Qualified Person when the nature, quality, quantity, and distribution of data are such that the tonnage and grade or quality of the mineralization can be estimated to within close limits and that variation from the estimate would not significantly affect potential economic viability of the deposit. This category requires a high level of confidence in, and understanding of, the geology and controls of the mineral deposit.
11.7.4 | Resource Category Definition |
The Mineral Resources category for the Project has been assigned according to S-K §229.1300 requirements as described above and reflect level of hydrogeological knowledge, sample availability and quality. The category classification is shown in Figure 11-16 and is described as follows:
Cauchari Lithium Brine Project

The resource estimate was prepared in accordance with the requirements of S-K §229.1300 and uses best practice methods specific to brine Resources, including a reliance on core drilling and sampling methods that yield depth-specific chemistry and drainable porosity measurements. This resource estimate was previously reported on April 19, 2019, without the application of a cut-off lithium concentration and inclusive of Reserves. On request of Allkem, a 300 mg/l lithium concentration cut-off was applied to the resource base which has results in an 11% decrease in Indicated Resources from those reported in 2019. Figure 11-17 provides the cut-off grade volume curve applied to the Measured, Indicated, and Inferred Resources. Table 11-6 summarizes the lithium Resources with the 300 mg/l lithium concentration cut-off and exclusive of Mineral Reserves.
Mr. F. Reidel AIPG (the QP), is of the opinion and warns that the reporting of Mineral Resources exclusive of Mineral Reserves should not be applied to brine Resources and the numbers reported in Table 11-6 may contain certain errors related to the mixing of Resources and Reserves under pumping conditions.

The cut-off grade is based on the various inputs and formula below:
The cut-off grade was elevated to 300 mg/l to increase margin and de-risk the uncertainties around price fluctuations. The cut-off grade is used to determine whether the brine pumped will generate a profit after paying for costs across the value chain.
Factors that may affect the Brine Resource estimate include: locations of aquifer boundaries; lateral continuity of key aquifer zones; presence of fresh and brackish water which have the potential to dilute the brine in the wellfield area; the uniformity of aquifer parameters within specific aquifer units; commodity price assumptions; changes to hydrogeological, metallurgical recovery, and extraction assumptions; density assignments; and input factors used to assess reasonable prospects for eventual economic extraction. Currently, Mr. F. Reidel AIPG (the QP), does not know of any environmental, legal, title, taxation, socio-economic, marketing, political, or other factors that would materially affect the current Resource estimate.
11.8 | Potential Risks in Developing the Mineral Resource |
The potential risks with the development of the Mineral Resources are mainly related to the behavior of the hydrogeological units in the Archibarca Fan under pumping conditions. Greater than forecasted mixing of the pumped brine with freshwater from the upper aquifer in the Archibarca fan could lead to lower Li concentrations in the pumped brine than forecasted. The recommendations outlined in Section 7 include additional drilling and testing to reduce this potential risk.

12. Mineral Reserves Estimates
This Section of the Technical Report describes 1) the construction of the three-dimensional groundwater flow and transport model; 2) the steady state- and transient calibration methodology and results; 3) simulation results of the proposed brine production scenario using the calibrated model and an estimate of Mineral Reserves and 4) description of sensitivity analysis completed around the calibration and the limitations of the modeling.
12.1 | Introduction |
A numerical groundwater flow and transport model using the FEFLOW 7.1 code was developed for the Project in support of this PFS. The numerical model was built, calibrated, and operated by the DHI Group with the guidance of Mr. F. Reidel AIPG. The specific objectives of the model in support of this PFS are to:
● | Calibrate the model to a normalized root mean squared error (NRMSE) of 10% or less under pre-mining, steady-state conditions. |
● | Calibrate the model in transient mode for pumping tests at wells CAU07R and CAU11R. |
● | Simulate brine abstraction of the wellfields located in the NW- and SE Sectors of the Project area to support an annual LCE production of 25,000 tonnes over a 30-year mine life, assuming 67 percent lithium process recovery efficiency. |
● | Evaluate preliminary well-field configurations and pumping schedules to minimize the potential dilution of lithium concentrations in the discharge of the production wells. |
● | Prepare an estimate of Mineral Reserves for the Project. |
12.2 | Reserve Estimate Methodology, Assumptions, and Parameters |
12.2.1 | Model Construction |
The model domain includes the Salar de Cauchari and the southern part of the Salar de Olaroz (Flosolutions, 2018) and is shown in Figure 12-1. The domain encompasses the unconsolidated sediments of the Cauchari basin extending from the center of the salar, to the upper reaches of the alluvial fans in the catchments east, south, west, and north of the salar. The far northern boundary of the model domain falls within the southern part of Salar de Olaroz. The Leapfrog geological model described in Chapter 6 was imported into the FEFLOW model. Areas of bedrock outcrops surrounding the sedimentary deposits are excluded from the model domain.
Cauchari Lithium Brine Project
SEC Technical Report Summary
The topographic elevation of the model domain ranges from 3,925 masl in Salar de Olaroz to 4,210 masl in the northeast corner of the domain. The base of the model has an elevation of between 3,332 m and 3,409 m for a total simulated sediment thickness in the Salar of 600 m.
12.2.1.1 | Meshing and layering |
The model has a total of 3,702,105 nodes, 7,144,704 elements, and 32 layers. Elements located where bedrock is present are inactive in the flow and transport simulations. Therefore, the total number of active elements is 6,476,125. All elements are triangular prisms with elemental diameters ranging from approximately 80 m in the center of Salar de Cauchari to approximately 380 m at the outer edges of the model domain. Mesh refinement is also implemented in the vicinity of pumping wells reaching an elemental diameter down to approximately 5 m.
The layer thickness ranges from 1.0 m to 20 m. Layers 1 and 2 have thicknesses ranging from 1 m to 5 m and 3 m to 4 m, respectively. Layer thicknesses for Layers 3 to 32 are uniform, ranging from 15 m thick in Layer 3 to 20 m thick for Layers 4 to 32. The finite element mesh is shown in Figure 12-2.

12.2.1.2 | Flow Boundary Conditions |
There are two primary groundwater inflow processes at the Salar de Cauchari: recharge by direct precipitation and indirect recharge from catchments surrounding the Salar de Cauchari hydrogeological system as described previously in Chapter 6 Groundwater discharges at lower elevations from the nucleus of the Salar via evaporation. The modelled water balance components are further quantified hereafter. A schematic of the key boundary condition types is presented in Figure 12-3. The boundary condition zones are discussed in this section.
Figure 12-3 – Schematic of key flow boundary processes.
The bottom or floor of the model domain is treated as a no-flow boundary. Evaporation and recharge boundary conditions are applied to Layer 1. The lateral recharge boundary conditions are applied to the outer boundaries in Slices 1 to 19 of the model. Where a lateral recharge boundary is not defined, the lateral horizontal boundary of the model is treated as a no-flow boundary.
Cauchari Lithium Brine Project
SEC Technical Report Summary
12.2.1.3 | Direct Recharge |
In the FEFLOW model, recharge is applied only to the alluvial fan materials, at a rate of 25.6 mm/y, or 20% of the mean annual precipitation of 136 mm/year estimated at the Salar (DHI, 2018). This area is shown in Figure 12-3 and corresponds to the top of the elements on which there are no applied nodal boundary conditions. No recharge was applied to the nucleus of the salar, which are assumed to be areas of net groundwater discharge. Additionally, this approach is considered conservative as any predictive wellfield drawdown and capture area will be overestimated under the absence of direct recharge.
12.2.1.4 | Catchment Inflows |
In addition to direct recharge, Salar de Cauchari receives indirect or lateral recharge at higher elevations within the catchments that surround the salar. Figure 12-4 shows the catchments that generate lateral groundwater flow into the Cauchari Basin and the annual average flow rates for each catchment from the water balance (DHI, 2018). The catchment inflows were treated as flux or second type boundary conditions. The boundary nodes were generally applied below the water table in Slices 1 to 19 of the model, provided that the outer boundary element was not a bedrock element. For each sub-catchment, the flux boundary nodes were assigned a total inflow equal to the flux values shown in Figure 12-4.
The most significant lateral groundwater inflow is the 143 l/s estimated for the Archibarca fan.
Second type boundary conditions nodes were applied to the north and south lateral boundaries, with flux values defined during the steady state calibration. The inflows associated with these boundaries resulted in a steady state water balance for the pre-mining condition. Under steady state groundwater flow conditions, the total groundwater inflow via direct and indirect recharge must equal the total groundwater loss via evaporation. The calibrated flows across the north and south boundaries required to balance evaporative outflow are shown in Figure 12-4.

12.2.2 | Evaporation |
The primary groundwater discharge process in Salar de Cauchari is evaporation from the soil surface. Figure 15-5 illustrates the distribution of the evaporation function in the model. In all cases, the vertical evaporation rate is defined as a linear function of water table depth from ground surface. When the water table is at the topographic elevation, the applied evaporation rate equals the maximum value shown in Figure 12-5. The evaporation rate decreases linearly with depth from ground surface to an extinction depth, defined to range from 1.5 m to 3 m, at which point, the applied evaporation rate is equal zero. Therefore, the evaporation is considered dynamic in the FEFLOW model. Table 12-1 lists the evaporation parameters for five zones within the FEFLOW model.
Figure 12-5 – Linearized EVT-Model used in implicit approach.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Table 12-1 – Evaporation parameters.
Water Type | Location | Maximum Evaporation Rate (mm/d) | Extinction Depth (m) |
Fresh | Edge of Alluvial Fans | 2.5 | 1.5 |
Brine | from Clay | 0.7 | 5 |
Brine | Salar Nucleus | 0.3 | 3 |
Brine | Carbonates | 0.15 | 5 |
Brine | Archibarca | 1.2 | 1.5 |
The magnitude of the maximum evaporation in each of the five zones was calibrated using target evaporation fluxes from the water balance (FloSolutions, 2018). As a general rule, two factors control the maximum evaporation rate. The first is the salinity of the groundwater. Brine from the Salar nucleus was assigned a lower maximum evaporation rate, consistent with the well-established reduction in evaporation of brine compared to fresh water. A second criterion is the hydraulic conductivity of the soil. More permeable sediments, such as the alluvial fan materials of the Archibarca fan, have higher maximum evaporation rates than lower-permeability materials like the clays, due to a coarse soils’ greater ability to transmit groundwater to the evaporative surface.
As a consequence of these factors, five evaporation zones are defined, as shown in Figure 12-6 and listed in Table 12-1. The five zones can be subdivided into functional groups as follows:
● | Evaporation of freshwater at the edge of the alluvial fans. This evaporation zone occurs at the edge of the majority of alluvial fan catchments surrounding Salar de Cauchari. |
● | Evaporation of brine at the edge of the alluvial fans in two areas: |
- | Archibarca alluvial fan. The Archibarca fan feeds Rio Archibarca on the northern part of the western edge of the FEFLOW model domain. This catchment contributes a larger volume of lateral recharge than the other alluvial fan basins (see Figure 12-4). The brine present in the deeper Archibarca fan deposits discharges at the salar in two areas shown in Figure 12-6. |
- | Brine discharge from carbonate soils associated with catchment S-11 occurs in the southwestern portion of the model. |
● | Evaporation from brine within the Salar is divided into two zones characterized by the surficial stratigraphic material. |
- | Evaporation from halite from the salar’s nucleus in the approximate center of the Salar de Cauchari. |
- | Evaporation from the clay core surrounding the halite. |
Each of these zones is treated as a FEFLOW transfer boundary node, corresponding to a Cauchy or third-type boundary condition. The value of the maximum evaporation transfer rate in each zone was adjusted during the calibration such that the total evaporation from all zones matched the conceptual water budget.

12.2.3 | Pumping Wells |
Pumping tests were completed in two wells, CAU07R and CAU11R. These pumping tests are described in Section 7.4 and further below in Section 12.3.1. These two existing wells are simulated as multilayer wells in the FEFLOW model.
Cauchari Lithium Brine Project

In addition, 67 lithium brine extraction wells are simulated boundary nodes as Well for the predictive model simulations. The pumping wells in the model are shown in Figure 12-7. The coordinates of the proposed extraction wells are shown in Table 12-2 and Table 12-3. The brine production wellfields are located in the NW Sector of the Project (Archibarca fan area) and the SE Sector. The depth for the Archibarca production wells varies between 160 m and 360 m depth. The Archibarca production wells are screened in Slices 11 and 21 of the FEFLOW model. The depth of the SE wells varies between 120 m and 460 m. The SE production wells are screened in Slices 9 to 26 of the FEFLOW model.

The conceptual specific storage (Ss) for all active zones of the model is 1x10-4 m-1, except the clay units with a Ss value of 1x10-6 m-1. The specific storage was calibrated to the pumping test data (see Section 12.3.1), and only minor adjustments to this parameter were required (see Section 12.4).

12.2.6 | Initial Lithium Concentration Distribution |
The initial distribution of lithium concentrations for the reserve estimate simulations was based on the kriged (SGeMS) lithium concentration used in the resource estimation for the areas within the Allkem properties and as described in chapter 11 above. Third party information (Exar) outside the Allkem properties was used to expand the distribution of initial lithium concentration laterally and vertically throughout the FEFLOW model domain. The initial distribution of lithium concentrations is shown in Figure 12-9. Approximately 1.25 million t of lithium Resources are present in the FEFLOW model domain at the beginning of the simulation.
Figure 12-9 – Distribution of initial lithium concentration.
12.2.7 | Density Considerations |
Fluid density is an important factor in the movement of groundwater in and around a brine salar. Key flow processes related to Salar de Cauchari are illustrated in Figure 12-10. Groundwater is recharged by fresh rainfall primarily at higher elevations, with a secondary component of direct recharge as shown in Figure 12-3. Freshwater flows through the alluvium around the salar and discharges via evaporation or stream baseflow near the freshwater-brine interface and, to a lesser degree, within the salar itself. When dense brine has established itself in the salar, the circulation within the salar, caused by evaporation and density-driven convection within the clay core and halite, is generally a small proportion of the total water balance. In other words, the recharge and discharge of freshwater occurs at a larger rate than the circulation and evaporation of brine. Additionally, the vertical anisotropy identified at some of the alluvial fans (Archibarca fan in particular) precludes vertical groundwater flow, minimizing mixing of freshwater and brine.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Figure 12-10 – Conceptualization of key density-dependent flow processes relevant to Cauchari JV Project.
The computational burden of simulating variable-density groundwater flow is significant. For the purposes of the predictive model simulation, the three-dimensional groundwater flow and transport model was configured to assume single-density groundwater. Figure 12-11 illustrates the generalized approach to simulating the flow processes in the three- dimensional model. As in the variable-density system shown in Figure 12-10 groundwater recharges at higher elevations and at the margins between the alluvial fans and the clay core of the salar. This freshwater from recharge flows toward the salar and discharges at approximately the location of the freshwater-brine interface due to the change in topographic slope that coincides with the brine-freshwater interface. Due to the lower evaporation rate of brine in the salar compared to freshwater and brine discharge at the margins, additional groundwater discharges via evaporation in the center of the salar, but the magnitude of this flow is lower than that which discharges at the margins of the salar.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Figure 12-11 – Salar de Cauchari numerical modeling approach.
As a general observation, ignoring density effects will result in greater groundwater mixing and dilution. Therefore, the use of a single-density model for the predictive simulations will provide a conservative estimate of the reserve by allowing more mixing with recharging freshwater.
12.2.8 | Solver and Convergence Criteria |
The flow solver used in the FEFLOW runs is the Algebraic Multigrid (AMG) Methods for Systems (SAMG) solver with a maximum of 50 AMG cycles and 200 PCG iterations. The transport equation was also solved with the SAMG solver with these settings: a root mean squared (RMS) Euclidian L2 error tolerance of 1x10-5, with a maximum of 10 outer iterations.

12.3 | Mine and Plant Production Scenarios |
12.3.1 | Calibration Methodology |
The flow model was calibrated under steady state and transient conditions to:
1) fit the static water levels in Project area wells.
2) match the conceptual water balance.
3) simulate two pumping tests.
A combination of manual and automated calibration was completed under both steady state and transient conditions. This section describes the calibration methodology. Calibration results are presented in Section 12.4.
12.3.1.1 | Steady State Calibration |
The steady state calibration was designed to identify the best fit values of all hydraulic conductivities as well as the transfer coefficients used to simulate evaporation (Section 12.2.4). Manual and automated calibrations were completed. For the automated calibration, FEFLOW’s built-in version of the PEST parameter optimization program, FePest, was applied.
Water level measurements in 23 monitoring wells within the model domain were used as calibration targets. Figure 12-12 shows the location of the monitoring wells used as head calibration targets, and Table 12-6 lists these wells and the target water level for the well.
In addition to head calibration targets, flux targets from the conceptual water balance were introduced to the Fepest run. Table 12-7 lists the calibration targets for fluxes in the FEFLOW domain. The total recharge for the FEFLOW domain is estimated at approximately 730 l/s and groundwater discharge through evaporation from the model domain is approximately 810 l/s. The conceptual water balance closes with a 10 % error which is considered adequate for defining the numerical model calibration targets.

12.3.1.2 | Transient Calibration |
Transient water level data from two pumping tests were used to calibrate the model with regard to changing hydraulic heads over time. The pumping well locations are shown on Figure 12-7. The pumping tests were conducted in 2018 and 2019. The pumping period of the tests had a duration of 30 days at CAU07R and 30 days at CAU11R (Table 12-8). The pumping rates ranged from 22 l/s at CAU07R to 18 l/s at CAU11R.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Pumping well CAU07R is screened in the intercalated sand, gravel, and clay units, including the Archibarca fan (see Figure 12-13). CAU11R is screened in the halite, clay, and lower sand units (see Figure 12-14).
The changes in hydraulic head since the beginning of pumping (drawdowns) and not absolute water level values were used as calibration targets. This approach was chosen since the absolute hydraulic head values were constrained during the steady state calibration, and the focus of the transient calibration is the magnitude of the change in hydraulic head that is induced by pumping. The observation wells for each pumping test and their completion intervals and distances to the pumping wells are summarized in Table 12-9.
A node spacing of 1 to 5 m around the pumping wells (see Section 12.2.1) is insufficient to resolve turbulent well losses, and the observed hydraulic head from the pumping wells themselves were not used for the transient calibration.
Table 12-8 – Water balance components within the FEFLOW domain.
Name | Pumping Rate (L/s) | Start | End | Duration (days) |
CAU07R | 22 | 11/12/2018 | 9/1/2019 | 30 |
CAU11R | 18 | 25-10-2018 | 23-11-2018 | 30 |
All hydro stratigraphic units that intersected by the pumping and observation wells were included in the transient calibration as adjustable parameters. After each change in the adjustable parameters, the steady state model simulation was re-run, and the steady state hydraulic heads were imported into the transient model as initial heads from which the drawdown was computed.

The calibration results are shown in Figure 12-15 with a map-view of the calibration residuals. The simulated and observed hydraulic head values are compared in Table 12-11. The residual mean of the calibrated model is -0.2 m, and the absolute residual mean is 1.0 m, for a normalized root mean squared error (NRMSE) of 7.2%.
The maximum negative residual is at PP03, where the head value is over-predicted by 1.9 m. The maximum positive residual is at PSJ03, where the well’s water level is under- predicted by 2 m. Overall, the model is considered calibrated with respect to pre-mining steady state heads, due to a NRMSE that is less than 10% and an absolute residual mean that is 1 m or less.

12.4.3 | Calibration to Flows |
The fluxes from the calibrated steady state model are shown in Table 12-12. The total inflow simulated by the model is 731 l/s, which is equal to the 730 l/s of the conceptual model. The simulated direct recharge of precipitation, 190 l/s, is within 2% of the conceptual value of 194 l/s. The lateral recharge from catchments located east and west of Salar de Cauchari is 455 l/s in the FEFLOW and 443 l/s in the conceptual model.
Table 12-12 shows that the total simulated evaporative losses from the FEFLOW model equal 734 l/s, compared to the conceptual value of 810 l/s. The model predicts that 61% of the evaporation occurs along the margins of the salar: 39% of the total evaporation occurs from freshwater portions of the margin, and 22% of the total evaporation occurs from the saltwater portions of the salar margin. Only 2% of the total evaporation is simulated to occur from within the salar itself, in the halite or clay zones. This is consistent with the assumptions made in the simplification of the variable density system into a single density model (see Section12.7.2). The FEFLOW water balance closes with an error less than 1% which is considered adequate for the predictive model simulations further described in Section 12.5 below.

The simulated drawdowns at CAU11R and its three observation points are compared to observed drawdowns on Figure 12-17. The simulated drawdown at CAU11-MB (completed in the clay and halite units is approximately equal to the observed drawdown (Table 12-14). The overall shape of the drawdown is also generally matched, except for the 5-day period near the end of the test. CAU11-MA completed in the lower sand, and CAU11-MC, completed in the shallow halite display observed drawdowns below 2.0 m. The model predicts higher drawdowns at both locations.

It is possible that poor development (clogging) of the CAU11-MA observation well resulted in the reduced drawdown measurements during the pumping test.

12.5.1 | Wellfield Production Rates |
The calibrated model was used to predict lithium extraction rates from the Salar de Cauchari during the proposed 30-year mine life with a target lithium carbonate equivalent (LCE) extraction rate of 25 kilotonnes per year (ktpy) assuming a process lithium recovery efficiency of 67%. The locations of the brine production wells are shown in Figure 12-7 and Table 12-2 and Table 12-3. As described in Section 12.3.1 the brine production wells are simulated boundary condition nodes as well.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Twenty-two (22) wells are proposed for the NW Sector wellfield in the Archibarca fan area during the first nine years of mine life. The NW production wells target the brine in the lower part of the Archibarca unit. Each well is simulated to pump at a rate of 24 l/s as supported by the CAU07 pumping test results. The NW wellfield pumping schedule is illustrated in Figure 12-18. During the initial three-year ramp-up period, the combined pumping rate increases from 168 l/s in Year 1 to 312 l/s during Year 3.
Forty-five (45) wells are proposed for the SE Sector wellfield with a pumping schedule as shown in Figure 12-18. As for the NW wellfield, production wells are replaced on a regular basis during the LOM. The SE wellfield targets brine in the halite, clay, and Lower Sand units from Year 9 to Year 30 of operations. The proposed total pumping rate from the southeast wells is a constant 480 l/s.

12.5.2 | LCE Production |
Figure 12-19 shows the simulated annual LCE contained in brine pumped from the NW and SE wellfield areas as input to the evaporation ponds. Figure 12-20 shows the modelled LOM evolution of Li concentrations. The initial Li concentration in the pumped brine from the NW wellfield is 580 mg/l in Year 1 and gradually declines to 520 mg/l by Year 8. The initial Li concentration of the brine pumped from the SE wellfield gradually declines from 490 mg/l in Year 9 to 465 mg/l in Year 30. The resulting Li concentrations applied in the PFS cost analyses as further described in Section 19 are: 580 mg/l for Years 1-5, 545 mg/l for Years 6-9, and 490 mg/l for Years 9 – 30. It is expected that through further optimization of the well-field configurations and pumping schedules the overall LOM Li concentrations can be improved.

12.6 | Mineral Reserve Estimate |
The lithium reserve estimate was carried out based on a FEFLOW multi-species simulation. Each resource type is a specie in the model. Four species were defined for characterizing the Measured, Indicated and Inferred Resources and any brine coming from outside the Cauchari properties. first seven years of production (with production in the NW extending for 9 years). Lithium Reserves derived after Year 7 from the Measured and Indicated Resources in the NW and SE wellfield areas were categorized as Probable Reserves. Results of a separate model simulation to evaluate the potential effect of the neighboring LAC brine production (according to LAC Updated Feasibility Study of January 2020) showed that there is no material impact on the Cauchari Reserve Estimate. An operating agreement between Allkem and LAC regulates and mitigates any effects of intercompany wellfield interference in Salares de Olaroz and Cauchari.

Year 1 from wells located in the NW Sector. In Year 9, brine production switches across to the SE Sector of the Project.

Additional hydrogeological test work will be required in the next stage of evaluation to adequately verify the quantification of hydraulic
parameters in the Archibarca fan area and in the Lower Sand unit as indicated by the sensitivity analysis carried out on the model results. Mineral Reserves are derived from and included within the M&I Resources in resource table (Table
11‑6).

Indicated Resources of 894,000t LCE contained in the West Fan Unit are not included in this PFS production profile. There is a reasonable prospect that through
additional hydrogeological test work Inferred Resources in the Lower Sand Units will be converted to M+I Resources.

The cut-off grade is based on the various inputs and formula below:
The cut-off grade was elevated to 300 mg/l to increase margin and de-risk the uncertainties around price fluctuations. The cut-off grade is used to determine whether the brine pumped will generate a profit after paying for costs across the value chain.

12.7 | Assumptions and Reserve Estimate Risks |
12.7.1 | Sensitivity Analyses |
Eighteen sensitivity runs were completed on the FEFLOW model parameters selection. The sensitivity analyses indicate that model parameter selection result in a relative stable model, suitable for the simulations carried out as part of this PFS. The selection of values for the anisotropy ratio of the horizontal and vertical hydraulic conductivities in the Archibarca unit are important to the evolution of lithium concentrations and the reserves derived from the NW wellfield area; further work is recommended to verify the quantification of these parameters.
12.7.2 | Limitations |
The predictions of the numerical model developed for this study are based on the creation of a digital representation (3D numerical model) of built and natural systems. The construction of the model requires assumptions and simplifications, which create inherent limitations in the accuracy of the results. Any decision made based on the modeling work should consider these assumptions and limitations. The calibration of the numerical model, although it reduces the parametric uncertainty of the numerical model, does not represent a unique solution to reproduce the values observed in the field or in the conceptual model. This means that more than one system of parameters or boundary conditions system can reproduce the observed field data. The groundwater numerical model provides a reasonable representation of the system and the compatibility with the conceptual model and the intervals of the probable or exact solutions.

13. Mining Methods
This section describes the brine extraction methods and related infrastructure.
13.1 | Mine Method – Brine Extraction |
Lithium bearing brine hosted in pore spaces within sediments in the salar will be extracted by pumping using a series of production wells to pump brine to evaporation ponds for its concentration; extraction of brine does not require open pit or underground mining.
Based on the results of the pumping tests carried out for the Project (as described in Section 7 above), the brine abstraction from Salar de Cauchari will take place by installing and operating two conventional production wellfields. The brine production will take place initially from a wellfield in the NW Sector immediately adjacent to the evaporation ponds on the Archibarca Fan from Year 1 through to Year 9. After Year 9 it is planned that the brine production will shift to a second wellfield constructed in the SE Sector.
The annual numerical values and totals for the Life of Mine (LOM) production, including the quantities pumped from the wellfields with associated solution grades, the overall recovery, and final salable product are detailed in the Table 13-1.
Table 13-1 – Annual numerical values and totals of Life of Mine (LOM) production
Note: Overall Recovery is calculated on an annual basis of lithium produced relative to the lithium contained in the brine produced by the wellfields as input to the evaporation ponds. This calculated Overall Recovery is affected by the pond inventory and production ramp-up causing temporary fluctuations in calculated annual recovery, an Overall Recovery of 66% is assumed during steady state operation.
13.1.1 | NW Wellfield |
The combined production from the NW wellfield will ramp up from 170 l/s in Year 1 to approximately 460 l/s in Year 8. It is expected that pumping rates of individual wells in the NW wellfield will vary between 20 l/s and 30 l/s so that up to 22 wells may be required to meet the overall brine production requirements. The NW production wells are located on the main access roads between the evaporation ponds and will be drilled and completed to a depth of approximately 360 m in the lower brine aquifer of the Archibarca fan. The upper part of the production wells through the Archibarca fresher to brackish water aquifer will be entirely cemented and sealed to an approximate depth of 140 m to avoid any freshwater inflow into the wells. Below 140 m depth the wells will be completed with 12-inch diameter production casing. The wells will be equipped with submersible pumping equipment (50 HP pumps). It is planned that the NW production wells will discharge immediately into evaporation ponds No 1 and No 2 without intermediate boosting or storage requirements. Figure 12-7 show the general layout of the NW production wellfield.
13.1.2 | SE Wellfield |
It is planned that brine production will shift to the SE wellfield in Year 9. The combined production rate from the SE wellfield will be in the order of 480 l/s from Year 9 though to Year 30. It is expected that pumping rates of individual wells in the SE wellfield will vary between 10 l/s and 20 l/s so that up to 44 wells may be required to meet the overall production requirements. Production wells will be drilled and completed to a depth of approximately 460 m with 12-inch diameter stainless steel production screens. The wells will be equipped with submersible pumping equipment (50 HP pumps). It is planned that the SE production wells will discharge through feeder pipelines into an intermediate storage pond at the northern limit of the SE wellfield. Brine will be pumped through a main trunk pipeline from the intermediate storage pond to the evaporation ponds at the plant site in the NW Sector of the Project. Figure 12-7 show the general layout of the SE production wellfield.

SEC Technical Report Summary
13.2 | Wells Materials, Pads, and Infrastructure |
Infrastructure in the well field is planned to include well pads, access roads and power generation. Each brine well will have its own generator and diesel storage tank, and each tank will have a residence time of 72 hr. A diesel truck will feed the diesel tanks to keep the diesel generators running. All wells will be connected by road to the booster station. Drilling pads will be elevated to as much as 1.5 m above the salar surface to mitigate flooding risks. Drill pad dimensions will have a platform area sufficient to house the required diesel generators and control instrumentation.

14. Processing and Recovery Methods
14.1 | Test Work and Recovery Methods |
Specific brine evaporation and metallurgical recovery test work at the Cauchari site has not progressed as of the Effective Date. The Cauchari brine has been sampled and tested with results indicating similar characteristics to the Allkem Olaroz site brine. This is expected to be due to the proximity (20 km) and interconnectedness of the Olaroz and Cauchari Salars.
Refer to Chapter 10 for further details. The variance on Mg/Li and Li/ SO4 ratios for both Cauchari and Olaroz brines are low enough to state that Cauchari brine could be processed using similar processing technology to that applied in the Olaroz production facility. The Olaroz process design has been successfully proven to produce lithium carbonate since 2015.
As such, the mass and energy balance and associated process design for the Project is based on the Allkem Olaroz processing technology with the incorporation of some modifications to address operational issues, capitalizing operational experience and lessons learned from Allkem Olaroz operations.
14.2 | Process Design |
The Cauchari Project will include the design and installation of production wells, evaporation ponds and a processing plant to obtain 25,000 tpy of battery grade lithium carbonate (Li2CO3). A general block diagram of the process is shown in Figure 14-1.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Figure 14-1 – General Block Diagram for the Process.
Cauchari Lithium Brine Project
SEC Technical Report Summary
As a general overview of the process, the brine that feeds the lithium carbonate (Li2CO3) Plant is obtained from two brine production wellfields as described in Chapter 13. The NW wellfield will be operated for the first 9 years of the Project; brine production will switch to the SE wellfield during Year 9 and onwards.
The brine is pumped to the evaporation ponds, designed to crystallize mainly Halite and some Glauber salt, Glaserite, silvite and borate salts. At certain points slaked lime is added to the brine, which removes a large part of Magnesium (Mg) as magnesium hydroxide. The Calcium (Ca) is precipitated as gypsum, thus also removing dissolved sulphate (SO4). After the evaporation ponds, the brine is fed to the Li2CO3 plant, where, through a series of purification processes, solid lithium carbonate is obtained, to be shipped according to the final customer requirements. A general process flow diagram is shown in Figure 14-2.
Figure 14-2 – General Process Diagram.
The brine is concentrated until it reaches a Li concentration of 7,000 mg/l. An overall evaporation ponds and lithium carbonate plant recovery of 66% for lithium is modelled based on industrial operational results. A more detailed description of the process for both the evaporation ponds and the lithium carbonate plant are presented below.
Cauchari Lithium Brine Project
SEC Technical Report Summary
14.3 | Process Flowsheet and Description |
14.3.1 | Brine Concentration in the Solar Evaporation Ponds |
The evaporation ponds will be fed with brine from the NE wellfield between Years 1 and 9 and from the SE wellfield from Years 9 through 30. The configuration of the wellfield is shown in Figure 12-7 and described in Sections 12.2.1.2 and Chapter 13. The brine produced by the SE wellfield has a lower lithium concentration than brine from NW wellfield but with very similar chemistry. Therefore, the area of the evaporation ponds will expand to maintain the same productions levels. These additional evaporation ponds will be located in the SE Sector Project tenements. The brine produced from the SE wellfield will feed the southern evaporation ponds to be then sent to the northern evaporation ponds.
The area required for the evaporation ponds is calculated based on the evaporation rate and rainfall impact defined for the site conditions. The solar evaporation ponds are designed with a large area and low depth, absorbing solar energy, thus creating a natural evaporation rate of the water contained in the brine. The brine is saturated in salts and during its concentration these salts are crystalizing in the ponds. These crystallized salts are kept inside the pond until they reach a defined height, after which they are harvested and transported to specific stockpiles located outside of the ponds area but inside the properties for the Project.
The construction of the evaporation ponds will incorporate the topography survey of the area in order to minimize material handling. If needed, there will be a surplus area for construction purposes. Both the floor and dykes inside of the ponds are then covered with geomembranes, which are plastic impermeable membranes, to avoid leakage of the brine from inside the ponds.
Once the ponds are filled with brine, the brine transfer between ponds will be executed with pumps, which will allow precise control of the flow between ponds. It is planned to install a liming plant to accomplish impurities elimination, which naturally occur in the brine, such as magnesium and sulphates. This is done via slaked lime addition, which is split into two different stages, that is, at two different lithium concentrations. The brine from the wells is fed to the first group of ponds for pre-concentration, after which it is treated in the first reactors of the liming plant, where the brine is mixed with slaked lime in order to remove the magnesium from the brine. The slurry is then transferred by gravity to the first decantation ponds, where the precipitated solids are separated from the lithium brine. The brine is then fed to a second group of evaporation ponds, after which it is pumped to additional liming reactors, installed as a backup to remove the remaining Mg from the brine through the addition of more slaked lime. Just like the first liming reactors, the reacted slurry is then transferred by gravity to the second decantation pond, to generate separation of the solids. The concentrated brine is then fed to the last group of evaporation ponds. When the lithium concentration is suitable for lithium processing, the brine is stored in reservoir ponds before feeding to the lithium carbonate plant.
Due to changes in lithium concentration expansions of the solar evaporation area are considered after Year 5 and Year 9. Brine production from the NW and SE wellfields will also increase accordingly. The variance in evaporation pond area, brine extraction, harvested salts and solids from liming plant are shown in Table 14-1.

Solids in decantation ponds | ton/y | 294,913 | 319,662 | 192,382 |
14.3.2 | Lithium Carbonate Plant |
The lithium carbonate plant is a chemical facility that receives the concentrated brine from the evaporation ponds and, through a series of chemical processes, generates lithium carbonate battery grade in a solid form. All impurities that are still left in the brine after the evaporation ponds are removed in the lithium carbonate plant, through specific stages described below.
The first stage of the lithium carbonate plant is the calcium and magnesium removal stage. A solution of soda ash and slaked lime are added to the concentrated brine from the evaporation ponds in an agitated reactor. Mg and Ca will precipitate as magnesium hydroxide (Mg(OH)2) and calcium carbonate (CaCO3). The slurry is then filtered, and the Mg and Ca free brine is sent to the next stage. The solids obtained from the filtering stage are re-pulped and sent directly to the first sludge pond.
The lithium rich brine is fed to an ion exchange stage, to remove remaining calcium, magnesium, and any other di/tri valent metals in the brine. The impurity free brine is then sent to carbonation reactors. Here the addition of a soda ash solution and high temperatures result in lithium carbonate precipitating (technical grade), which is filtered on a belt filter, repulped and centrifuged. This can be directly dried and sold as technical grade. In order to obtain battery grade, the pulp is transported to another purification stage. The mother liquor generated from the belt filter is recycled to the ponds in order to recover the remaining lithium.
The purification stage consists of the generation of lithium bicarbonate through the reaction in agitated reactors of the solid lithium carbonate and gaseous CO2 at low temperature. The lithium bicarbonate is much more soluble in water than lithium carbonate, allowing the separation from any residual soluble and insoluble impurities. With the use of an IX stage utilizing a specific selective resin, any boron and/or di/tri valent metals left in the solution are removed, and a highly pure bicarbonate solution is fed to a desorption stage. With the increase of temperature (up to 80°C) the CO2 is desorbed, and solid lithium carbonate is re- precipitated. The slurry is centrifuged, dried, reduced in size (milled) and packaged in maxibags, to be finally transported to the clients.

SEC Technical Report Summary
14.3.3 | Reagents for the Process |
14.3.3.1 | Prepared slaked lime |
The main reagent used in the process is lime. The lime is slaked with water. This process is executed in a liming plant, which is conventional equipment applied in the industry, and it will be installed near the evaporation ponds.
For the lithium carbonate plant, hydrated lime (Ca(OH)2) will be considered for the process. This hydrated lime will be received directly from the vendors and dissolved in agitated tanks to obtain the required solution for the process.
14.3.3.2 | Preparation of the Soda Ash solution |
The second main reagent used in the process is soda ash (Na2CO3), which is used both in the Ca/Mg removal stage and the carbonation stage. Both processes consider a total consumption of soda ash which will be prepared in a specific soda ash plant. In this plant the soda ash is dissolved from a solid state to the solution required for the precipitation, which has a concentration of 28% w/w.
Process water is used for the preparation of the soda ash solution, water that is recycled from the belt filter. Both the process water and solid soda ash are fed to a preparation tank in the soda ash plant, and temperature is controlled for an efficient dissolution. After a defined agitation time, the solution is filtered and pumped to a storage tank, from which it is fed to the process according to the defined consumption.
14.4 | Summary of Mass and Water Balances |
14.4.1 | Water Purification |
Although the lithium carbonate plant incorporates the re-utilization of water within the process in various stages, the injection of fresh water is necessary at specific steps, including for the final product washing. Fresh water for the process will be supplied by alluvial water wells located to the southeast of the Project area and will be treated in a water treatment plant to remove all impurities before being pumped into the lithium carbonate plant. The water treatment plant will consider a reverse osmosis process.
Refer to Chapter 15 for further information related to freshwater infrastructure.

SEC Technical Report Summary
14.4.2 | Equipment Cleaning |
Due to the brine characteristics, specifically all the salts and impurities in the brine, there is generation of salt deposits and scaling inside the equipment of the lithium carbonate plant. These must be periodically cleaned, using a sulfuric acid solution (H2SO4) with a concentration of 18%. The frequency of cleaning will be defined by the operations area. The solution obtained after the equipment cleaning is sent directly to the first sludge pond.

14.4.3 | Solid Waste Management |
A small fraction of waste solids is generated in the lithium carbonate plant, that are mainly impurities removed from the brine. The main solids are a mixture of magnesium hydroxide and calcium carbonate. These solids will be discarded upon the salt stockpiles as further discussed in Chapter 15.
14.5 | Operations staff |
The total forecast number of operational personnel including on-duty and off-duty will be approximately 270 to 300 people for both wellfield and processing facilities.
14.6 | Conclusions |
It is the opinion of Mr. M. Dworzanowski, FSAIMM and FIMMM (the QP), that the described process design is reasonable and implementable. The process is standard and has been previously proven to produce similar products. The process design is based on conducted test work and reflects the related test work parameters. The process-related equipment is suitably sized and organized to produce the mentioned products in the quantities specified. The reagent and commodity consumption rates are deemed appropriate for the size of plant.
Cauchari Lithium Brine Project
SEC Technical Report Summary
14.7 | Recommendations |
For an optimization of the lithium recovery operations, there are several technologies to be evaluated as alternatives to guarantee the company’s future production in the long term. In particular, the carbonation plant effluents, and in particular the so-called “mother liquor”. This is recirculated in the process, discharging it back into the evaporation pond circuit. This mother liquor stream still contains a certain concentration of lithium, which is not lost when recirculated, but at the same time the impurities that this stream may have, are also incorporated into the evaporation pond circuit. To improve this recovery process, it is recommended to evaluate alternatives that allow recovering as much lithium as possible from this mother liquor stream but leaving the other elements or impurities to avoid its recirculation.

15. Infrastructure
This section describes infrastructure related process, support services and commodities related to the Cauchari Project.
15.1 | Access |
15.1.1 | Access Roads |
The main road access to the Project is from the city of San Salvador de Jujuy, RN 9, which heads north-northwest for approximately 60 km, and then meets RN 52 near the town of Purmamarca. Following Route 52 for 50 km will lead to the eastern side of the Salinas Grandes Salar. The road crosses this salar before ascending further and continuing south along the eastern margin of the Olaroz Salar. It then crosses west at the juncture of the Olaroz and Cauchari Salars. The total distance between the city of Jujuy and the Project area is approximately 230 km, and driving it takes approximately 4 hours. This highway continues on to the Chilean border at the Jama pass and connects to the major mining center of Calama and the ports of Antofagasta and Mejillones, in northern Chile. Driving distance to these ports is approximately 500 km and 570 km, respectively. This road is fully paved, from Jujuy to these Chilean ports. Planned Project facilities are within 1 km of Route 52.
The Project may also be accessed from the provincial capital of Salta by driving 27 km WSW from Salta to Campo Quijano, then continuing north for approximately 120 km along Route 51, through Quebrada del Toro, to the town of San Antonio de los Cobres, at an altitude of 3,750 masl. This route is paved, with the exception of the lower section through Quebrada del Toro and the upper section leading to San Antonio. From San Antonio de los Cobres, Route 51 leads west to the south of the Cauchari Salar, with route RP-70 providing access along the western side of the salar to reach the international road (Route 52). The distance from San Antonio to the Project is approximately 125 km entirely on well-maintained gravel roads.
15.1.2 | National Route 70 Detour |
The current Cauchari evaporation pond layout interferes with the current route of gravel road No.70. The detouring of this road will be required to effect the construction of the evaporation ponds (Figure 15-1). A feasibility study, detour application, and road construction must be allowed for in both project permitting schedule and capital expenditure.
The road detour engineering and trade-offs will be studied in the next project phase following commencement of the application process.
Delays in provincial or municipal approvals may impact the commencement of the project construction.

All the temporary installations will be removed after the construction phase has ended unless other uses are defined for some of them.
15.2.2 | Brine Extraction Wellfields |
The Project considers two (2) production wellfields as shown in Figure 12-7:
● | The NW wellfield in the Archibarca area, within the area of the evaporation ponds. All brine wells will be specifically located on top of the berms that divide the evaporation ponds, as shown on Figure 15-4. |
● | SE wellfield located in the SE Sector of the Project, within the area of the SE evaporation ponds. |
While the brine extracted from NW wellfield will be sent directly to the evaporation ponds, brine from the SE wellfield will be collected in a first group of evaporation ponds, and then pumped to the evaporation ponds in Archibarca through a 32.5 km pipeline. This pipeline will be built only once it is required, which is expected to happen in Year 9, and will operate until the end of Project life.
According to the mining plan defined for the Project, and as described in Section 18.2 of this document, the number of wells used during the life of the Project will vary as shown in Table 15-1.

● | Portable brine transfer pumps at the site of the southeastern transfer pond and other locations along the brine pipeline |
15.2.4 | Evaporation Ponds |
15.2.4.1 | Principal Evaporation ponds |
The principal evaporation ponds for the Project will be located off the salar in the Archibarca area as shown in Figure 15-5. Brine will be concentrated in these ponds through solar evaporation. Construction of these ponds involves mainly surface leveling, building up pond borders with material from the area, and waterproofing the base and sides of the ponds with a geomembrane.
Following variances in the lithium concentration in brine, expansions of evaporation ponds are planned for Year 5 and Year 9. The first pond expansion will be located near the principal evaporation ponds whilst the second expansion will be located in the SE Sector of the Project. These ponds will be fed with brine from the SE wellfield to be then sent to the principal evaporation ponds.

15.2.4.2 | Decantation Ponds |
Two decantation ponds will be considered in the Project, according to the process design, to remove all solids from the liquid stream that precipitate in the liming plant. These ponds are located west of the evaporation ponds, near the liming plant. The decantation ponds have similar construction characteristics to the evaporation ponds including geomembrane liners to prevent leakage from the ponds.
Cauchari Lithium Brine Project
SEC Technical Report Summary
15.2.4.3 | Reservoirs |
The reservoirs are located after the final evaporation ponds, and are smaller ponds, where concentrated brine is stored before being pumped to the lithium carbonate plant. Their construction characteristics are similar to those of the evaporation ponds.
15.2.4.4 | Pumping Stations |
Brine will be transferred from one evaporation pond to the next through pumping stations. These stations will be installed on the berm between the ponds. The power supply for each station will be aerial. Due to the topography of the area, no gravity transfer among the ponds will be carried out.
15.2.4.5 | Evaporation Pond internal roads |
Berms constructed between ponds will also serve as roads for truck circulation during pond harvesting, access to brine production wells, and transit for monitoring and maintenance activities. Some berms will be wider and constitute the main service roads for salt harvesting activities and will also include platforms and access for the brine production wells in the NW wellfield. The other berms will be sized to the minimum width required to allow safe pedestrian transit.
15.2.4.6 | Evaporation Pond area contour channels |
Contour channels will be built on the west side of the evaporation ponds to collect and divert any surface water run-off that might occur during the rainy season.
15.2.5 | Liming Plant |
The process requires that lime be added to the brine to increase precipitation of impurities - mostly as magnesium and calcium solids- originally dissolved in it. Based on the process design described in Section 17, lime will be added in two (2) stages of the evaporation ponds’ process, to maximize precipitation of the impurities. This liming plant will include the equipment required for this task and will be installed in a special building, located near the evaporation ponds/decantation ponds. Figure 15-6 shows the planned layout and design of the plant.

● | Moistening of earthwork material for structural fills during construction of ponds and plant platforms (during the construction phase). |
● | Irrigation and dust control on work fronts (during the construction phase, after which this task will be carried out with the clean water obtained from the WWTP). |
● | Water dilution for transfer pumps is used to transfer brine from one pond to another (during the construction phase of the water treatment plant, after which all the rejection water obtained from this water treatment plant will be used for dilution). |
● | Feeding the lithium carbonate process plant during production. |
The process plant requires two (2) types of water: industrial water and pure water. Industrial water will be used directly from the alluvial production wells, and pure water will be obtained from a Reverse Osmosis water treatment plant located near the lithium carbonate plant which treats the industrial water obtained from the alluvial production water wells.

15.7 | Construction Materials |
Project construction materials can be roughly separated into two different areas. The wellfield and ponds, and the industrial area.
The brine wells comprise mainly the well casing, its pump, manifold, and its electrical equipment. Then the brine pipelines are made of plastic materials (e.g., HDPE), and the ponds are run from an earthwork platform whit its embankment, and then lined (LLDPE, HDPE).
Regarding the industrial area, bulk materials are concrete foundations and pavement, steel structures and supports, steel and plastic piping, cables trays and wiring, etc.
Regarding equipment, thickeners, conveyors, cyclones, boilers, compressors, pumps, filters, steel and plastic tanks, agitators, centrifuges, bagging equipment, heat exchangers, etc.
The main characteristic for process piping and equipment is that they need to deal with salt incrustation, acid, hydroxide, etc., so in many cases plastic material and some exotic steels are used. Most of these materials require certain engineering progress to be specified, and at the same time they are not produced in Argentina. Therefore, purchasing these materials is an important issue to consider.
For the industrial plant, the Owner is responsible for the long lead items provision (process main equipment). Bulk materials and other equipment are on main contractor scope.
For the balance of plant (wellfield, ponds, and some other) equipment and material supply is by the Owner.
Logistics and Warehousing are segregated in the same way, it is the responsibility of whoever purchases it.
15.8 | Communications |
External communication on the Cauchari site is limited. Cellular communications are non-existent. The Project will rely on satellite internet and phone communications for external communication.
The local on-site communication will occur via various communication systems:
● | Site Data Network (WWAN wireless). |
● | Telephony Services. |
● | Video Surveillance (CCTV). |
● | Access Control Systems. |
● | Intruder Detection System. |
● | Mobile Radio Communication. |
● | Measuring and control instruments. |
● | Process Control System (PCS). |
● | Fire Detection System. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | Radio communication service. |
● | Satellite phone service. |
The main control system room, which will be located inside the process plant building, will house the necessary PC-based OIT. OITs will act as the control system SCADA servers as well as configuration and operator stations. The control room is intended to provide a central area from where the plant and well stations are operated and monitored and from which the regulatory control loops can be monitored and adjusted. All key process and maintenance parameters will be available for trending and alarm on the process control system. Centralization of the complete plant will be at the operation control room and the command of operations will be made remotely from the control system workstations.
15.9 | Security and Access Point |
Due to the remote site location, a minimum level of security is necessary. The main security function will be to man the gatehouse at the entrance to the plant and camp and monitor and provide guidance and direction to traffic entering and leaving the site.
Monitoring the weighbridge, fuel dispensing and onsite assets will also be carried out by the security staff. The facilities will include a gatehouse with access control, communications, parking, and appropriate area lighting. Certain areas will be equipped with security cameras and a monitoring room will be equipped with screens for surveillance of key areas where security or safety risks are considered high.
15.10 | Conclusions |
The Project support infrastructure has been reviewed and is deemed adequate by Mr. M. Dworzanowski, FSAIMM and FIMMM (the QP), to support the processing infrastructure and process operations described in this report.
15.11 | Recommendations |
Based on the experience that Allkem has in the execution of the Olaroz I and II projects, the country context, and the delays in certain types of materials. A detailed Long lead items (LLI) must be made and include, beyond the main equipment, those components that today their manufacture plays an important role due to the scarcity of raw materials for their manufacture.

16. Market Studies and Contracts
The information on the lithium market is provided by Wood McKenzie, a prominent global market research group to the chemical and mining industries. Wood Mackenzie, also known as WoodMac, is a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries.
Supplementary comments are provided by the Allkem internal marketing team based on experience with Olaroz Project product marketing.
16.1 | Overview of the Lithium Industry |
Lithium is the lightest and least dense solid element in the periodic table with a standard atomic weight of 6.94. In its metallic form, lithium is a soft silvery-grey metal, with good heat and electric conductivity. Although being the least reactive of the alkali metals, lithium reacts readily with air, burning with a white flame at temperatures above 200°C and at room temperature forming a red-purple coating of lithium nitride. In water, metallic lithium reacts to form lithium hydroxide and hydrogen. As a result of its reactive properties, lithium does not occur naturally in its pure elemental metallic form, instead occurring within minerals and salts.
The crustal abundance of lithium is calculated to be 0.002% (20 ppm), making it the 32nd most abundant crustal element. Typical values of lithium in the main rock types are 1 – 35 ppm in igneous rocks, 8 ppm in carbonate rocks and 70 ppm in shales and clays. The concentration of lithium in seawater is significantly less than the crustal abundance, ranging between 0.14 ppm and 0.25 ppm.
16.1.1 | Sources of Lithium |
There are five naturally occurring sources of lithium, of which the most developed are lithium pegmatites and continental lithium brines. Other sources of lithium include oilfield brines, geothermal brines, and clays.
16.1.1.1 | Lithium Minerals |
● | Spodumene [LiAlSi2O6] is the most commonly mined mineral for lithium, with historical and active deposits exploited in China, Australia, Brazil, the USA, and Russia. The high lithium content of spodumene (8% Li2O) and well-defined extraction process, along with the fact that spodumene typically occurs in larger pegmatite deposits, makes it an important mineral in the lithium industry. |
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | Lepidolite [K(Li,Al)3(Si,Al)4O10(OH,F)2)]is a monoclinic mica group mineral typically associated with granite pegmatites, containing approximately 7% Li2O. Historically, lepidolite was the most widely extracted mineral for lithium; however, its significant fluorine content made the mineral unattractive in comparison to other lithium bearing silicates. Lepidolite mineral concentrates are produced largely in China and Portugal, either for direct use in the ceramics industry or conversion to lithium compounds. |
● | Petalite [LiAl(Si4O10)] contains comparatively less lithium than both lepidolite and spodumene, with approximately 4.5% Li2O. Like the two aforementioned lithium minerals, petalite occurs associated with granite pegmatites and is extracted for processing into downstream lithium products or for direct use in the glass and ceramics industry. |
16.1.1.2 | Lithium Clays |
Lithium clays are formed by the breakdown of lithium-enriched igneous rock which may also be enriched further by hydrothermal/metasomatic alteration. The most significant lithium clays are members of the smectite group, in particular the lithium-magnesium-sodium end member hectorite [Na0.3(Mg,Li)3Si4O10(OH)2]. Hectorite ores typically contain lithium concentrations of 0.24%-0.53% Li and form numerous deposits in the USA and northern Mexico. As well as having the potential to be processed into downstream lithium compounds, hectorite is also used directly in aggregate coatings, vitreous enamels, aerosols, adhesives, emulsion paints and grouts.
Lithium-enriched brines occur in three main environments: evaporative saline lakes and salars, geothermal brines and oilfield brines. Evaporative saline lakes and salars are formed as lithium-bearing lithologies which are weathered by meteoric waters forming a dilute lithium solution. Dilute lithium solutions percolate or flow into lakes and basin environments which can be enclosed or have an outflow. If lakes and basins form in locations where the evaporation rate is greater than the input of water, lithium and other solutes are concentrated in the solution, as water is removed via evaporation. Concentrated solutions (saline brines) can be retained subterraneous within porous sediments and evaporites or in surface lakes, accumulating over time to form large deposits of saline brines.
The chemistry of saline brines is unique to each deposit, with brines even changing dramatically in composition within the same salar. The overall brine composition is crucial in determining a processing method to extract lithium, as other soluble ions such as Mg, Na, and K must be removed during processing. Brines with a high lithium concentration and low Li:Mg and Li:K ratios are considered the most economical to process. Brines with lower lithium contents can be exploited economically if evaporation costs or impurities are low. Lithium concentrations at the Salar de Atacama in Chile and Salar de Hombre Muerto in Argentina are higher than the majority of other locations, although the Zabuye Salt Lake in China has a more favorable Li:Mg ratio.

16.1.2 | Lithium Industry Supply Chain |
Figure 16-1 below shows a schematic overview of the flow of material through the lithium industry supply chain in 2021. Raw material sources in blue and brown represent the source of refined production and TG mineral products consumed directly in industrial applications. Refined lithium products are distributed into various compounds displayed in green. Refined products may be processed further into specialty lithium products, such as butyllithium or lithium metal displayed in grey. Demand from major end-use applications is shown in orange with the relevant end-use sectors in yellow.
Figure 16-1 – Lithium Industry Flowchart (Wood Mackenzie).
Lithium demand has historically been driven by macro-economic growth, but the increasing use of rechargeable batteries in electrified vehicles over the last several years has been the key driver of global demand. Global demand between 2015 and 2021 has more than doubled, reaching 498.2kt LCE with a CAGR of 16.8% over the period. Adding to this growth, in 2022 global lithium demand is expected to increase by 21.3% to 604.4 kt LCE as demand for rechargeable batteries grows further. Over the next decade, global demand for lithium is expected to grow at a rate of 17.7% CAGR to 2,199 kt in 2032.
16.1.3 | Global demand for Lithium |
Lithium demand has traditionally been used for applications such as in ceramic glazes and porcelain enamels, glass-ceramics for use in high-temperature applications, lubricating greases and as a catalyst for polymer production. Between 2020 and 2022, demand in these sectors rose steadily by approximately 4% CAGR. Growth in these applications tends to be highly correlated to industrial activity and macro-economic growth. Wood Mackenzie forecast the combined growth of lithium demand from industrial markets is likely to be maintained at approximately 2% per annum from 2023 to 2050.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Rechargeable batteries represent the dominant application of lithium today, representing more than 80% of global lithium demand in 2022. Within the rechargeable battery segment, 58% was attributed to automotive applications which has grown at 69% annually since 2020. This segment is expected to drive lithium demand growth in future. To illustrate, Wood Mackenzie forecast total lithium demand will grow at 11% CAGR between 2023 and 2033: of this lithium demand attributable to the auto-sector is forecast to increase at 13% CAGR; whilst all other applications are forecast to grow at 7% CAGR. Growth is forecast to slow in the following two decades as the market matures (Figure 16-2).
Figure 16-2 – Global Demand for Lithium by End Use, 2030 - 2050 (Wood Mackenzie).
Lithium is produced in a variety of chemical compositions which in turn serve as precursors in the manufacturing of its end use products such as rechargeable batteries, polymers, ceramics, and others. For rechargeable batteries, the cathode, an essential component of each battery cell, is the largest consumer of lithium across the battery supply chain. Demand profiles for lithium carbonate and hydroxide is determined by the evolution in cathode chemistries. The automotive industry mainly uses NCM and NCA cathodes, often grouped together as “high nickel”; and LFP cathodes. High nickel cathodes consume lithium in hydroxide form and generally has a higher lithium intensity; whilst LFP cathodes mainly consume lithium in carbonate form and lithium content is lower. LFP cathodes are predominantly manufactured in China.
Lithium in the form of lithium hydroxide and lithium carbonate collectively accounted for 90% of refined lithium demand in 2022. These two forms are expected to remain important sources of lithium in the foreseeable future reflecting the share of the rechargeable battery market in the overall lithium market (Figure 16-3). The remaining forms of lithium include technical grade mineral concentrate (mainly spodumene, petalite and lepidolite) used in industrial applications accounting for 7% of 2022 demand; and other specialty lithium metal used in industrial and niche applications.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Figure 16-3 – Global Demand for Lithium by Product, 2023 - 2050 (Wood Mackenzie).
Lithium products are classified as ‘battery-grade’ (“BG”) for use in rechargeable battery applications and ‘technical-grade’ (“TG”) which is primarily used in industrial applications. TG lithium carbonate can also be processed and upgraded to higher purity carbonate or hydroxide products.
Lithium hydroxide is expected to experience exponential growth on the back of high-nickel Li-ion batteries. Demand for BG lithium hydroxide is expected to grow at 10% CAGR 2023-2033 to reach 1,133kt LCE in 2033, up from 450 kt LCE in 2023. Wood Mackenzie predict lithium hydroxide to be the largest product by demand volume in the near term. However, growth of LFP demand beyond China may see BG lithium carbonate reclaim its dominance.
Wood Mackenzie forecast LFP cathodes will increase its share of the cathode market from 28% in 2022 to 43% by 2033. This drives growth in lithium carbonates demand. Wood Mackenzie predicts lithium carbonate demand will grow at 14% CAGR between 2023 and 2033; slowing as the market matures.
16.1.4 | Market Balance |
The lithium market balance has shown high volatility in recent years. A large supply deficit resulted from historical underinvestment relative to strong demand growth in EVs. The rise in prices over the last few years has incentivized investment in additional supply. However, the ability for supply to meet demand remains uncertain given the persistence of delays and cost increases across both brownfield and greenfield developments.
For battery grade lithium chemicals, Wood Mackenzie predicts the market will remain in deficit in 2024. In 2025, battery grade chemicals are expected to move into a fragile surplus before falling into a sustained deficit in 2033 and beyond. Notably, technical grade lithium chemicals may be reprocessed into battery grade to reduce the deficit. However, the capacity and ability to do so is yet unclear.
Cauchari Lithium Brine Project
SEC Technical Report Summary
16.2 | Lithium Prices |
Lithium spot prices have experienced considerable volatility in 2022 and 2023. Prices peaked in 2022, with battery grade products breaching US$80,000 / t. However, spot prices fell significantly during Q1 2023 before stabilizing in Q2 2023. A combination of factors can explain the price movements including the plateauing EV sales, slowdown of cathode production in China; and destocking through the supply chain, partially attributed to seasonal maintenance activities and national holidays.
Contract prices have traditionally been agreed on a negotiated basis between customer and supplier. However, in recent years there has been an increasing trend towards linking contract prices to those published by an increasing number of price reporting agencies (“PRA”). As such, contracted prices have tended to follow spot pricing trends, albeit with a lag.
16.2.1 | Lithium Carbonate |
Continued demand growth for LFP cathode batteries will ensure strong demand growth for BG lithium carbonate. This demand is expected to be met predominantly by supply from brine projects. Given the strong pricing environment, a large number of projects have been incentivized to come online steadily over the coming years. Wood Mackenzie forecast prices to decline as additional supply comes online. However, Wood Mackenzie forecasts a sustained deficit in battery-grade lithium chemicals to commence from 2031. Over the longer term, Wood Mackenzie expect prices to settle between US$26,000/t and US$31,000/ t (real US$ 2023 terms) (Figure 16-4).
Figure 16-4 – Lithium Carbonate Price Outlook, 2023 - 2050 (Wood Mackenzie).
Notably, the market for BG carbonates is currently deeper and the spot market more liquid than hydroxide due to the size and experience of its main market of China. In addition, BG carbonates are used in a wider variety of batteries beyond the EV end use. TG lithium carbonate demand for industrial applications is forecast to grow in line with economic growth. However, TG lithium carbonate lends itself well to being reprocessed into BG lithium chemicals (either BG carbonate or BG hydroxide). The ability to re-process the product into BG lithium chemicals will ensure that prices will be linked to prices of BG lithium chemicals.
Cauchari Lithium Brine Project
SEC Technical Report Summary
16.2.2 | Lithium Hydroxide |
The market for BG lithium hydroxide is currently small and relatively illiquid compared to the carbonate market. Growth in high nickel cathode chemistries supports a strong demand outlook. Most BG hydroxide is sold under long term contract currently, which is expected to continue. However, contract prices are expected to be linked to spot prices and therefore are likely to follow spot price trends albeit with a lag. Over the longer term, Wood Mackenzie expect hydroxide prices to settle at between US$25,000 and US$35,000/t (real US$ 2023 terms) (Figure 16-5).
Figure 16-5 – Lithium Hydroxide Price Outlook, 2023 - 2050 (Wood Mackenzie).
16.2.3 | Chemical Grade Spodumene |
In 2022, demand from converters showed strong growth resulting in improved prices. After years of underinvestment, new capacity has been incentivized and both brownfield and greenfield projects are underway. Notably, these incremental volumes are observed to be at a higher cost and greater difficulty, raising the pricing hurdles required to maintain supply and extending timelines for delivery.
Wood Mackenzie forecasts a short period of supply volatility in the years to 2030, moving from surplus to deficit, to surplus before entering into a sustained deficit beyond 2031. Reflecting this dynamic, prices are expected to be in line with market imbalances. Wood Mackenzie forecast a long-term price between US$2,000/t and US$3,000/t (real US$2023 terms) (Figure 16-6).

16.3 | Offtake Agreements |
As of the date of this Technical Report, Allkem has no existing formalized commercial agreements in place for the sale of lithium carbonate from the Sal de Vida Project. Allkem remains in discussions with potential customers. In line with the Project execution schedule, these discussions are expected to advance to negotiations throughout the course of the Project.
16.4 | Risk and Opportunities |
16.4.1 | Price volatility |
Recent pricing history demonstrates the potential for prices to rise and fall significantly in a short space of time. Prices may be influenced by various factors, including global demand and supply dynamics; strategic plans of both competitors and customers; and regulatory developments.
Volatility of prices reduces the ability to accurately predict revenues and therefore cashflows. At present, Allkem’s agreements include index-based or floating pricing terms. In a rising market, this results in positive cashflows and revenues; in a falling market the financial position of the company may be adversely impacted. Uncertainty associated with an unpredictable cashflow may increase funding costs both in debt and equity markets and may therefore impact the company’s ability to invest in future production. Conversely, a persistently stronger pricing environment may also permit self-funding strategies to be put into place.
Cauchari Lithium Brine Project
SEC Technical Report Summary
16.4.2 | Macroeconomic conditions. |
Allkem produces lithium products which are supplied to a range of applications including lithium-ion batteries, the majority being used within the automotive sector and energy storage systems; industrial applications such as lubricating greases, glass, and ceramics; and pharmaceutical applications. Demand for these end uses may be impacted by global macroeconomic conditions, as well as climate change and related regulations, which in turn will impact demand for lithium and lithium prices. Macroeconomic conditions are influenced by numerous factors and tend to be cyclical. Such conditions have been experienced in the past and may be experienced again in future.
16.4.3 | Technological developments within battery chemistries. |
The primary growth driver for lithium chemicals is the automotive battery application, which accounts for more than 60% of demand today. Technology within automotive cathodes and cathode chemistries are continuously evolving to optimize the balance between range, safety, and cost. New “Next Generation” chemistries are announced with regularity, which carries the risk that a significant technology could move the automotive sector away from lithium-ion batteries. On a similar note, new technologies could also increase the intensity of lithium consumption. For example, solid state and lithium metal batteries could require more lithium compared to current lithium-ion battery technology. Despite the potential for technological innovations, the impact to the lithium market over the short-medium term is expected to be limited given the extended commercialization timelines and long automotive investment cycles which are a natural inhibitor to rapid technological change.
16.4.4 | Customer concentration |
Allkem is currently exposed to a relatively limited number of customers and limited jurisdictions. As such, a sudden significant reduction in orders from a significant customer could have a material adverse effect on our business and operating results in the short term. In the near term, this risk is likely to persist. As the battery supply chain diversifies on the back of supportive government policies seeking to establish localized supply, in particular in North America and Europe, there will be scope to broaden the customer base, however the size of automakers, the concentration in the automobile industry and the expected market growth will entail high-volume and high-revenue supply agreements. This risk is closely monitored and mitigative actions are in place where practicable.
Cauchari Lithium Brine Project
SEC Technical Report Summary
16.4.5 | Competitive environment |
Allkem competes in both the mining and refining segments of the lithium industry presently. We face global competition from both integrated and non-integrated producers. Competition is based on several factors such as product capacity and scale, reliability, service, proximity to market, product performance and quality, and price. Allkem faces competition from producers with greater scale; downstream exposures (and therefore guaranteed demand for their upstream products); access to technology; market share; and financial resources to fund organic and/or inorganic growth options. Failure to compete effectively could result in a materially adverse impact on Allkem’s financial position, operations, and ability to invest in future growth. In addition, Allkem faces an increasing number of competitors: a large number of new suppliers has been incentivized to come online in recent years in response to favorable policy environment as well as higher lithium prices. The strength of recent lithium price increases has also incentivized greater investment by customers into substitution or thrifting activities, which so far have not resulted in any material threat. Recycling will progressively compete with primary supply, particularly supported by regulatory requirements, as well as the number of end-of-life battery stock that will become available over the next decade as electric vehicles or energy storage systems are retired.
16.5 | Conclusion |
Wood Mackenzie, also known as WoodMac, is a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries. It is the opinion of M. Dworzanowski, FSAIMM and FIMMM (the QP) that the long-term pricing assessment indicated in this section is deemed suitable for economic assessment of the Project at the current level of study.
16.6 | Recommendations |
Market analysis will continue to evolve during the project development phase. It is recommended that Allkem continue with ongoing market analysis and related economic sensitivity analysis.
Risk factors and opportunities in technological advancements, competition and macroeconomic trends should be reviewed for relevancy prior to major capital investment decisions. Remaining abreast of lithium extraction technology advancements, and potential further test work or pilot plant work may provide opportunities to improve the Project economics.
It is recommended to further develop a diversified customer base and secure offtake agreements to support the next study phase and potential expansion.

17. Environmental Studies, Permitting, Social or Community Impacts
This section describes the current status of environmental studies, permitting and social engagements undertaken by the Project.
It is the opinion of the QPs that the current Cauchari plans are adequate for environmental compliance, permitting, and local community relations. The estimated closing and reclamation costs are US$23.1M. In terms of environmental studies, permitting and social factors, Cauchari is in compliance with all federal and provincial regulations.
Cauchari has successfully completed the required environmental studies to support its exploration programs from 2011. In September 2019 it submitted an Environmental Baseline for the Exploitation stage which to date is under evaluation by the provincial mining authority. Environmental monitoring activities are being carried out in compliance with current permit requirements.
According to the mining environmental provincial decree 7751/23 (published in March 2023) the Cauchari project is working with expert teams around the adequacy of the provisions and activities foreseen for the Mine Closure Plan included in the Environmental Impact Report of Exploitation that is under evaluation, and must be adapted later according to new provisions included in Decree 7751/23.
17.1 | Environmental Baseline and Impact Studies |
As indicated above, the Environmental Impact Assessment is submitted at its baseline, depending on the stage of the project, whether exploration and/or exploitation, and is renewed biannually to keep the permit in force. This is regulated by Provincial Decree N° 5.771/2023 (previous Decree N° 5772/2010).
In the case of Cauchari, it has successfully completed various environmental studies required to support its exploration programs between 2011 and the present. The last Environmental Impact Assessment approval was in 2017 for the exploration stage (Resolution 002-DMYRE/2017, Resolution 084-DMyRE/2018 and Resolution 001-DmyRE/2019). Then, in September 2019 it submitted an Environmental Baseline for the Exploitation stage which to date is under evaluation by the provincial mining authority.
The aforementioned studies have been prepared by interdisciplinary teams of external consultants, specialized, and authorized by the province.
All the Environmental Impact Assessment are submitted to the Provincial Mining Directorate and subject to a participatory evaluation and administrative process with provincial authorities (Indigenous People Secretariat, Water Resources Directorate, Environmental Ministry, Economy, and Production Ministry, among others) and communities of influence, until the final approval resolution is obtained. In the case of SAS, the evaluation process is carried out with the participation and dialogue of the indigenous communities of Manantiales de Pastos Chicos, Olaroz Chico, Huancar, Termas de Tuzgle de Puesto Sey, Catua, Paso de Jama and Susques.
17.2 | Project Permitting |
While the Environmental Impact Assessment is the most important permit for any mining activity, each stage of the Project has necessarily required other types of permits.
All the permits listed below in Table 17-1 are in the process of renewal before the corresponding provincial authorities, while others are under analysis by the company until the effective exploitation activities begin.

17.3 | Other Environmental Concerns |
The Project is partially located in the Olaroz-Cauchari Fauna and Flora Reserve, that was created in 1981 under provincial law 3820. The reserve is a multi-use area that allows for agricultural and mining activities and scientific investigation programs. Once the EIA Exploitation stage is approved by the provincial authority, the operation stage of the Project must be consistent with the multi-use reserve status.
17.4 | Social and Community impacts |
The company has been actively involved in community relations since the properties were acquired by Allkem prior to initial drilling on the Project in 2011. Although there is minimal habitation in the area of the salar, Allkem (previously as AAL) has consulted extensively with the local indigenous communities and employs members of these communities in the current exploration activities.
The formal EIA permitting process will address community and socio-economic issues; it is expected the Project will have a positive impact with the creation of new employment opportunities and investment in the region. As part of the EIA, a comprehensive consultation was undertaken with members of the local communities, regarding the Project development and its associated opportunities for the community members.
17.5 | Mine Closure and Reclamation Plan |
The Project has submitted a mine closure plan within the Exploitation Environmental Impact Assessment which is still under evaluation.
Cauchari Lithium Brine Project
SEC Technical Report Summary
This plan must be approved by the Mining Provincial Directorate. It includes general measures such as decommissioning, physical, and chemical stabilization, land reclamation or rehabilitation, revegetation and post-closure monitoring measures and actions. From a social perspective, it includes social programs aimed at mine workers and the population of the communities interrelated to the mine and must be updated in the next renewal of the Environmental Impact Assessment, all in accordance with the provisions of Decree No. 7751/23.
In addition to these specific plans for the closure, The Project has also presented an Environmental Contingency Plan that establishes the policies, objectives, plans, actions, procedures, and indicators necessary for the development of its operations in an environmentally compatible manner and in compliance with applicable national, provincial, and municipal environmental legal requirements. This Plan is the minimum standard to be met by all personnel associated with the activities carried out at the mine (own personnel, contractors, service providers, auditors, inspectors and/or visitors) and at all sites of the mining operation and is submitted together with the Environmental Impact Assessment and updated with each renewal.
Finally, and since the approval of the Exploration EIA, Allkem carries out participatory and biannually environmental monitoring campaigns, sampling almost 30 representative points of fauna, flora, soil, climate, water, effluents, limnology, air quality, noise, limnology, landscape characteristics and ecosystem characterization, etc. Then, the reports of the results of these points are submitted to the Provincial Directorate of Mining, which evaluates them according to emission and legal conservation parameters and issues the corresponding approval.
According to the mining environmental provincial decree 7751/23 (published in March 2023) SAS is working with expert teams in the adequacy of the provisions and activities foreseen for the Mine Closure Plan included in the Environmental Impact Report of Exploitation that is under evaluation, as indicated above.
The estimated closing and reclamation cost is US$23.1M.

The capital cost estimate was prepared by Worley Chile S.A. and Worley Argentina S.A. (collectively, Worley) in collaboration with Allkem. The estimate includes capital cost estimation data developed and provided by Worley, Allkem, and current estimates.
The capital cost was broken into direct and indirect costs.
18.1.1.1 | Direct costs |
This encompasses costs that can be directly attributed to a specific direct facility, including the costs for labor, equipment, and materials. This includes items such as plant equipment, bulk materials, specialty contractor’s all-in costs for labor, contractor direct costs, construction, materials, and labor costs for facility construction or installation.

SEC Technical Report Summary
18.1.1.2 | Indirect costs |
Costs that support the purchase and installation of the direct costs, including temporary buildings and infrastructure; temporary roads, manual labor training and testing; soil and other testing; survey, engineering, procurement, construction, and project management costs (EPCM); costs associated with insurance, travel, accommodation, and overheads, third party consultants, Owner’s costs, and contingency.
18.1.1.3 | Quantity Estimation |
Quantity development was based on a combination of:
● | Basic design (engineered conceptual designs). |
● | Estimates from plot plans, general arrangements or previous experience, and order of magnitude allowances. |
Estimate pricing was derived from a combination of:
● | Current pricing from Allkem’s ongoing Projects and operations at Olaroz Stage 2 and Sal de Vida Stage 1. |
● | Estimated or built-up rates and allowances. |
● | Reconfirmed pricing from relevant contractors based on budget quantities and quotations. |
● | Labor hourly costs based on hourly labor costs built up to include labor wages, statutory payroll additives, insurances, vacation, and overtime provisions. |
● | The estimate considers execution under an EPC approach. |
The construction working hours are based on a 2:1 rotation arrangement, i.e.: 14 (or 20) consecutive working days and 7 (or 10) days off. The regular working hours at 9.5 hours per day but could be extended up to 12 hours of overtime. Whilst an agreement will need to be reached with the relevant trade unions, this roster cycle is allowed under Argentinian law and has been used for similar projects. Labor at the wellfields, ponds, process plant, and pipelines areas will be housed in construction camps, with camp operation, maintenance, and catering included in the indirect cost estimate. A productivity factor of 1.35 was estimated, considering the Project/site-specific conditions.
Sustaining capital is based on current requirements and considers some operational improvements such as continuous pond harvesting.
Engineering, management, and Owner’s costs were developed from first principles. The Owner’s cost estimate includes:
● | Home office costs and site staffing. |
● | Engineering and other sub-consultants. |
● | Office consumables, equipment. |
● | Insurance. |

18.2 | Operating Costs Basis of Estimate |
The operating costs estimate for Cauchari was updated by Worley (Chile) and reviewed by Allkem’s management team. The cost estimate excludes indirect costs such as corporate costs, overhead, management fees, marketing and sales, and other centralized corporate services. The operating cost also does not include royalties, and export taxes to the company.
Most of these costs are based on labor and consumables which are in use at Olaroz operation as a going concern.
18.2.1 | Basis of Operating Cost Estimate |
18.2.1.1 | Reagents |
Reagent consumption rates are estimated from the process design and benchmarked with Olaroz Stage 2 design. Prices for the main reagent supplies were obtained from costs prevailing for FY 2024 Budget and were based on delivery to site.
18.2.1.2 | Maintenance factor |
A maintenance factor based on industry norms and established practice at Allkem’s Olaroz plant was estimated and applied to each area to calculate the consumables and materials costs.
18.2.1.3 | G&A |
Annual general and administrative (G&A) costs include the on-site accommodation camp, miscellaneous office costs and expenditure on corporate social responsibility.
18.2.1.4 | Taxes, Royalties, and Other Agreements |
Current Provincial Mining royalty is limited to 3% of the mine head value of the extracted ore, calculated as the sales price less direct cash costs related to exploitation and excluding fixed asset depreciation. In addition, pursuant to Federal Argentine regulation Decree Nr. 1060/20, a 4.5% export duty on the FOB price is to be paid when exporting lithium products.

SEC Technical Report Summary
18.2.1.5 | Employee Benefit Expenses |
Cauchari project, like Olaroz Mine will be managed on a drive-in/drive-out basis, with personnel coming from the regional centers, primarily Salta and San Salvador de Jujuy. A substantial camp will be maintained that provides accommodation, recreation, meals, and a manned clinic. The Project will be supported with accounting, logistics, human resources, and supply functions based in an office in Jujuy, already established for Olaroz. Although these services already exist, economies of scale have not been considered for the Cauchari estimate.
The Cauchari operations will use the same work rotation as currently practiced at Olaroz Mine, depending on the operational area.
● | This consists of a 14 by 14 days rotation: based on fourteen days on duty and fourteen days off-duty, with 12-hour shifts per workday, applicable for staff at site. |
● | A 5 by 2-day rotation: based on a Monday-to-Friday schedule, 40 hours per week, and would be applicable only to personnel at the Jujuy city office. |
18.2.1.6 | Operation Transports |
Cauchari is located in the province of Jujuy at 3,900 m altitude, adjacent to the paved international highway (RN52) that links the Jujuy Provincial capital, San Salvador de Jujuy, with ports in the Antofagasta region of Chile that are used to export the lithium carbonate product and to import key chemicals, equipment and other materials used in the production of lithium carbonate. In addition, both Jujuy and Salta have regular flights to and from Buenos Aires.
The logistics cost to ship product out of site is included in the relevant Operating Cost breakdown. Reagents cost includes delivery-at-site prices.
Pricing for Cauchari transportation and port costs were based on the current Olaroz operations due to the 20km proximity of the Projects. The estimate includes freight, handling, depot, and customs clearance to deliver lithium carbonate either Freight on Board (FOB) Angamos Chile or Campana in Argentina.
Approximately 100 to 150 tonnes of lithium carbonate from the Cauchari will be trucked to port each day, equivalent to 4 to 6 trucks per day.
18.2.1.7 | Energy |
Natural gas is planned to generate the on-site power and process heating. Allkem’s Olaroz plant is currently connected to the GAS ATACAMA gas pipeline at the Rosario Compressor Station, located between Susques and Paso de Jama (border with Chile). The Atacama pipeline is of Ø 20” and connects Cornejo (Salta) to Mejillones (Chile) with a length of approximately 950 km, of which 520 km is in Argentine territory. The interconnection to the SDJ gas pipeline is at approximately km 470 (Rosario Compressor Station). Key details of the gas supply are outlined below:

18.3 | Conclusions |
The capital and operating cost for the Cauchari project was independently developed by Worley (Chile) and benchmarked with nearby and Allkem operated Olaroz Stage 2 construction and Olaroz Stage 1 operations, providing improved confidence in the presented costs.
The indicated capital and operational costs accurately reflect the incurred and future expected costs for the Cauchari project and can be utilized for economic analysis.
18.4 | Recommendations |
Allkem is currently constructing the Sal de Vida Stage 1 processing facility. Continued monitoring of costs and timelines can further enhance planning for Cauchari.
The Cauchari project was evaluated as a stand-alone green fields and current permitting applications reflect this approach. With the successful progression and operation of closely located Olaroz Mine, the project Capex and Opex estimates can be reviewed for synergistic opportunities during construction and operations that could improve overall Project Economics.

19. Economic Analysis
Certain information and statements contained in this section and in the report are forward-looking in nature. Actual events and results may differ significantly from these forward-looking statements due to various risks, uncertainties, and contingencies, including factors related to business, economics, politics, competition, and society.
Forward-looking statements cover a wide range of aspects, such as project economic and study parameters, estimates of Brine Resource and Brine Reserves (including geological interpretation, grades, extraction and mining recovery rates, hydrological and hydrogeological assumptions), project development cost and timing, dilution and extraction recoveries, processing methods and production rates, metallurgical recovery rate estimates, infrastructure requirements, capital, operating and sustaining cost estimates, estimated mine life, and other project attributes. Additionally, it includes the assessment of net present value (NPV) and internal rate of return (IRR), payback period of capital, commodity prices, environmental assessment process timing, potential changes in project configuration due to stakeholder or government input, government regulations, permitting timelines, estimates of reclamation obligations, requirements for additional capital, and environmental risks.
All forward-looking statements in this Report are necessarily based on opinions and estimates made as of the date such statements are made and are subject to important risk factors and uncertainties, many of which cannot be controlled or predicted. Material assumptions regarding forward-looking statements are discussed in this Report, where applicable. In addition to, and subject to, such specific assumptions discussed in more detail elsewhere in this Report, the forward-looking statements in this report are subject to the following general assumptions:
● | No significant disruptions affecting the project’s development and operation timelines. |
● | The availability of consumables and services at prices consistent with existing operations. |
● | Labor and materials costs consistent with those for existing operations. |
● | Permitting and stakeholder arrangements consistent with current expectations. |
● | Obtaining all required environmental approvals, permits, licenses, and authorizations within expected timelines. |
● | No significant changes in applicable royalties, foreign exchange rates, or tax rates related to the project. |
To conduct the economic evaluation of the project, Allkem’s team employed a cash flow model that allows for both before and after-tax analysis. The main inputs for this model include the capital and operating cost estimates presented in the previous chapters, along with an assumed production program based on the plant performance capability and the pricing forecast outlined in Section 16.
Using the cash flow model, it has been calculated the key project’s indicators, including a sensitivity analysis on the most critical revenue and cost variables to assess their impact on the project’s financial metrics.
Cauchari Lithium Brine Project
SEC Technical Report Summary
19.1 | Evaluation Criteria |
For the economic analysis, the Discounted Cash Flow (DCF) method was adopted to estimate the project’s return based on expected future revenues, costs, and investments. DCF involves discounting all future cash flows to their present value using a discount rate determined by the company. This approach facilitates critical business decisions, such as M&A activities, growth project investments, optimizing investment portfolios, and ensuring efficient capital allocation for the company.
Key points about the Discounted Cash Flow method:
● | The discount rate is based on the weighted average cost of capital (WACC), incorporating the rate of return expected by shareholders. |
● | All capital expenditures that will be incurred as part of project development are considered as sunk costs and excluded them from the present value calculations. |
The DCF approach involves estimating net annual free cash flows by forecasting yearly revenues and deducting yearly cash outflows, including operating costs (production and G&A costs), initial and sustaining capital costs, taxes, and royalties. These net cash flows are then discounted back to the valuation date using a real, after-tax discount rate of 10%, reflecting Allkem’s estimated cost of capital. The model assumes that all cash flows occur on December 31st, aligning with Allkem’s Fiscal Year.
The DCF model is constructed on a real basis without escalation or inflation of any inputs or variables. The primary outputs of the analysis, on a 100% Project basis, include:
● | NPV at a discount rate of 10%. |
● | Internal rate of return (IRR), when applicable. |
● | Payback period, when applicable. |
● | Annual earnings before interest, taxes, depreciation, and amortization (EBITDA). |
● | Annual free cash flow (FCF). |
19.2 | Financial Model Parameters |
19.2.1 | Overview |
The financial model is based on several key assumptions, including:
● | Production schedule in a Fiscal Year basis (July to June), including annual brine production, pond evaporation rates, process plant production, and ramp-up schedule. |
● | Projections of plant recoveries and lithium grades. |
● | Operating, capital, and closure costs for a 30-year operating life. |
Cauchari Lithium Brine Project

● | Operating costs related to wellfields, evaporation ponds, process plant, waste removal, site-wide maintenance and sustaining costs, environmental costs, onsite infrastructure and service costs, and labor costs (including contractors). |
● | Product sales assumed to be Free on Board (FOB) South America. |
19.2.2 | Production Rate |
The Cauchari Project nominal capacity of annual lithium carbonate is estimated to be 25,000t/year as described in the Chapter 12.
The Table 19-1 summarizes the production quantities, grades, overall recovery, average sale prices, revenues, investments, operating costs, royalties, taxes, depreciation/amortization, and free cash flows on an annual basis with LOM totals, among other things.

19.2.3 | Process Recoveries |
The basis for the process recoveries is included in Chapter 10, and the process design is outlined in Section 14.
19.2.4 | Commodity Prices |
Wood Mackenzie provided near and long-term price outlooks for all products in Q1 2023. As detailed in the Chapter 16, lithium spot prices have experienced considerable volatility in 2022 and 2023. This issue is addressed with sensitivity analyses.
With a lithium cut-off grade of 300 mg/l utilized, based on a breakeven cut-off grade for a projected lithium carbonate equivalent price of US$ 20,000 per tonne over the entirety of the LOM, and considering the economic value of the brine against production costs the applied cut-off grade for the resource estimate (300 mg/l) is believed to be conservative in terms of the overall estimated resource. Domains in the block model with grades below the 300 mg/l cut-off grade were not considered in the resource estimate; thus, with these assumptions, a reasonable basis has been established for the prospects of eventual economic extraction.
Furthermore, the assigned 300 mg/L cut-off grade is consistent with other lithium brine projects of the same study level, which use a similar processing method. The resource is relatively homogeneous in grade (as shown in the grade-tonnage curve of Figure 11 17), and the average concentration is well above the cost of production, with brine concentrated in low-cost solar evaporation ponds.
The price estimate for Lithium Carbonate is based on information provided by industry consultants Wood Mackenzie, based on their extensive studies of the lithium market. Actual prices are negotiated by Allkem with customers, generally as contracts related to market prices.
Mr. F. Reidel AIPG (the QP) understands the lithium market will likely have a shortfall of supply in the coming few years, which will support higher than inflation-adjusted historical prices. Based on 2022 and 2023 pricing to date, the Wood Mackenzie analysis is considered a reasonable basis for pricing through to 2025. By this time, a new technical report will likely be completed, outlining details for the feasibility study.

19.4 | Indicative Economics and Sensitivity Analysis |
To assess the robustness of the project’s financial results, a sensitivity analysis was conducted in a range of +/- 25% on the key variables that impact the Cauchari’s after-tax net present value (NPV). The sensitivity analysis explores the potential effects of changes in relevant variables, such as:
Cauchari Lithium Brine Project
SEC Technical Report Summary
● | Revenue variables: |
○ | Lithium carbonate prices |
○ | Production levels |
● | Cost variables: |
○ | Capital expenditure (CAPEX) |
○ | Operating expenses (OPEX) |
The results are graphically summarized in the Figure 19-1 and Table 19-2.
19.4.1 | Cauchari Project NPV@10% Sensitivity Analysis |
The sensitivity analysis examined the impact of variations in commodity prices, production levels, capital costs, and operating costs on the project’s NPV at a discount rate of 10%. The aim is to illustrate how changes in these crucial variables affect the project’s financial viability.
The following Table 19-3 and Figure 19-1 provide the insights into the NPV@10% associated with the fluctuations in the key variables.
From the analysis, the commodity price has the most significant impact on the Cauchari’s NPV, followed by production levels, OPEX, and CAPEX. Price emerges as the most influential factor and a mere 10% variation in price results in a 19% impact on the NPV. Even under adverse market conditions, such as unfavorable price levels, increased costs, and investment challenges, Cauchari remains economically viable.
The sensitivity analysis focused on individual variable changes, and the combined effects of multiple variable variations were not explicitly modeled in this analysis.

Figure 19-1 – Sensitivity chart.
Based on the assumptions detailed in this report, the economic analysis of Cauchari demonstrates positive financial outcomes. The sensitivity analysis further strengthens its viability, as it indicates resilience to market fluctuations and cost changes. The sensitivity analysis indicates that the greatest project risk is the lithium carbonate price despite the favorable price history of the last two years. Further, unlike production targets, this price risk is not within the control of Allkem.
By conducting this sensitivity analysis, it provides a comprehensive understanding of the project’s financial risks and opportunities. This approach allows for informed decision-making and a clear assessment of the Cauchari’s potential performance under various economic scenarios.
19.5 | Conclusion |
Based on the detailed assumptions, the economic analysis of the Cauchari Project demonstrates positive economic outcomes. The sensitivity analysis further indicates economic resilience to market and cost fluctuations.
The financial model incorporates and reflects the main input parameters outlined throughout this report. The financial model reflects the positive potential economic extraction of the resource.

20.3 | Possible adjoining disputes |
Given that as noted above, Allkem’s Cauchari properties adjoin its Olaroz properties, and that the mineral resource to be exploited by the three companies is mobile brine, it is highly likely that wells located near the borders of the properties, will extract brine across these borders. This fact creates the potential for legal conflicts among the companies that share the Mineral Resources contained in the continuous aquifer below the Cauchari and Olaroz Salars.
This problem of adjoining mineral properties, with a mobile resource beneath them, often occurs in oil and gas production, where it is solved via “unitization agreements” among the area concessionaries. Unitization agreements have been used in Argentina, in the oil and gas industry. It is recommended that in the case of the exploitation of the lithium rich Cauchari – Olaroz Salars, the companies involved proactively establish an agreement of this type among themselves.

21. Other Relevant Data and Information
21.1 | Product / Processing Options Trade Off Study |
As part previous study phases, Allkem requested Worley (Chile) to carry out a trade-off study to compare the final product/processing options as outlined below:
● | Alternative processing options, to include a technical summary of currently available options and potential new processing technologies. |
● | Recommendations with support for the selected processing methodology. |
● | Final Product – assuming a nameplate capacity of 25,000 tpy – the following product scenarios evaluated: |
○ | Scenario 1: on-site lithium carbonate battery grade. |
○ | Scenario 2: on-site lithium hydroxide. |
○ | Scenario 3: a mix of the two with lithium hydroxide being produced off-site. |
The trade-off study on product type delivery gathered sufficient economic and technical data to estimate capital investment and operational costs for the three product type options. The objective for this study was set to determine the CAPEX and OPEX gaps rather than deriving an accurate estimate that could be used outside this study.
A decision was made in favor of producing lithium carbonate battery grade on site, discarding the production of lithium hydroxide or a mix of the two products.
Accordingly, Worley were requested to complete the study and their cost estimates to AACE class 4 accuracy, based on the production of lithium carbonate battery grade on site, then transported via the Antofagasta port for distribution to customers in Asia.
This is reflected in relevant chapters of this report, including OPEX and CAPEX inputs to the economic model.
21.2 | Project Schedule |
A project schedule has been developed for the Cauchari project which considers the activities for the Project from the start of the feasibility stage up to the completion of the Plant Commissioning.
The Project major milestones are outlined in Table 21-1.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Table 21-1 – Major Project Milestones.
Milestone | Date |
Completion of value engineering and scope definitions following the DFS | Q4 2023 |
Completion of Feasibility Study - DFS | Q2 2024 |
Environmental Impact Study Approved | Q2 2025 |
Start Camp Construction | Q2 2025 |

Start Pond Filling with Brine | Q1 2027 |
First Brine Ready to be Processed | Q1 2028 |
First Lithium Carbonate | Q2 2028 |
Ramp Up Complete | Q4 2028 |
The evaporation ponds construction duration is estimated at 14 months. The plant construction will be delayed by 12 months to allow sufficient evaporation time for brine within the ponds to meet the process design criteria input requirements. It is estimated that the plant construction schedule will be similar to Allkem’s Olaroz II that is nearing commissioning completion and entering ramp-up phase as of the Effective Date.

22. Interpretation and Conclusions
22.1 | Geology, Resources and Reserves |
Based on the analysis and interpretation of the exploration, resource definition drilling, and hydrogeological test work carried out on the Cauchari Lithium Project between 2011 and 2019, the following concluding statements are prepared:
● | The geology consists of permeable alluvial fan material in the NW Sector of the Project and along the eastern and western external property boundaries. This fan material grades into finer grained materials towards the center of the salar. In the center of the salar a clay unit has been identified near surface that overlies a thick halite unit. Deep drilling intersections in the SE Sector of the Project have identified a relatively permeable Lower Sand unit between 400 m and 600 m depth that underlies the central halite. |
● | The composition of the lithium bearing brines has been characterized to depths of up to 600 m. The brine is amenable to conventional lithium recovery process technology. |
It is the opinion of the QPs that the salar geometry, brine chemistry composition and the specific yield of the salar sediments have been adequately defined to support the Measured, Indicated and Inferred Resource estimates.
A numerical groundwater flow and transport model was developed for the Project to simulate the proposed brine production over a 30-year mine life and to prepare a lithium reserve estimate. It is the opinion of the QPs that the FEFLOW model provides a reasonable representation of the hydrogeological setting of the Project area and that the model is adequately calibrated to be used for the preparation of the Mineral Reserve estimate.
22.2 | Mining, Processing, and Infrastructure |
The described mining method is deemed adequate to support economic brine extraction and is similar in configuration to other lithium brine extraction configurations witnessed on operating properties owned by Allkem.
It is the opinion of the QPs that the described process design is reasonable and implementable. The process is standard and has been previously proven to produce similar products. The process design is based on conducted test work and reflects the related test work parameters. The process-related equipment is suitably sized and organized to produce the mentioned products in the quantities specified. The reagent and commodity consumption rates are deemed appropriate for the size of plant.
The Project support and process infrastructure has been reviewed and is deemed adequate by the QPs to support the process and operations described in this report.

SEC Technical Report Summary
22.3 | Market Studies |
Wood Mackenzie, also known as WoodMac, is a global research and consultancy group supplying data, written analysis, and consultancy advice to the energy, chemicals, renewables, metals, and mining industries. It is the opinion of Mr. M. Dworzanoswki, FSAIMM and FIMMM (QP) that the long-term pricing assessment indicated in this section is deemed suitable for economic assessment of the Project at the current level of study.
22.4 | Environmental and Social Issues |
The Cauchari tenements are not subject to any known environmental liabilities. There have been historical ulexite / borax mining activities adjacent to the Cauchari JV in the north of the salar. These mining operations are generally limited to within three meters of the surface, and it is assumed that these borax workings will naturally reclaim when mining is halted due to wet season inflows.
22.5 | Project Costs and Financial Evaluation |
The capital and operating cost for the Cauchari project was independently developed by Worley (Chile) and benchmarked with nearby Olaroz Stage 2 construction and Olaroz Stage 1 operations, providing improved confidence in the presented costs.
The indicated capital and operational costs accurately reflect the incurred and future expected costs for the Cauchari project and can be utilized for economic analysis.

SEC Technical Report Summary
23. Recommendations
23.1 | Resources and Reserves |
23.1.1 | NW Wellfield Area |
It is recommended that two additional test production wells are installed in the lower Archibarca unit to verify the lateral continuity of the low permeability units (and/or anisotropy) between the upper freshwater aquifer and the underlying brine unit. Each well site will require the completion of two adjacent monitoring wells with isolated screened intervals in the upper and lower units. Complete 7-day pumping trials in each new test production well.
A minimum of 10 additional mini piezometers are installed at the toe of the Archibarca Fan and new evaporation measurements are undertaken to refine the water balance.
Low flow sampling is carried out in well CAU7M350, CAU17D, CAU18D, CAU20D, and 21D at five selected depth intervals to verify previous chemistry analysis.
23.1.2 | SE Wellfield Area |
It is recommended that a minimum of 3 diamond core exploration holes are drilled to convert Inferred Resource into Indicated Resources to a depth of 600 m in the SE Sector (Lower Sand and Halite/Clay units).
The spinner log test is carried out in CAU11R during a new short pumping test to verify the CAU11R pumping test results and interpretation.
A new test production well and two adjacent monitoring wells are drilled targeting the Lower Sand unit and a 20-day pumping test is completed.
23.1.3 | Regional Hydrogeology |
It is recommended that five multi-level piezometers are installed in and around the salar to improve the understanding of the distribution of piezometric heads. Groundwater samples should be taken from each multi-piezometer.
23.1.4 | Analytical Work |
Update the geological model and Resource Estimate with all new drilling results in the next project phase.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Update the conceptual hydrogeological model for the FEFLOW model domain in the next project phase.
Incorporate updated hydrogeological model, updated piezometric data, and any new pumping test results into the FEFLOW model and carry out further re-calibration.
Carry out FEFLOW brine production simulations to:
● | Optimize wellfield configuration to improve LOM Li concentrations. |
● | Evaluate environmental considerations to assess any potential restrictions to the production simulations. |
● | Prepare an updated Mineral Reserve estimate for the Project. |
23.2 | Mining, Processing, and Infrastructure |
For an optimization of the lithium recovery operations, there are several technologies to be evaluated as alternatives to guarantee the company’s future production in the long term. In particular, the carbonation plant effluents, and in particular the so-called “mother liquor”. This is recirculated in the process, discharging it back into the evaporation pond circuit. This mother liquor stream still contains a certain concentration of lithium, which is not lost when recirculated, but at the same time the impurities that this stream may have, are also incorporated into the evaporation pond circuit. To improve this recovery process, it is recommended to evaluate alternatives that allow recovering as much lithium as possible from this mother liquor stream but leaving the other elements or impurities to avoid its recirculation.
Based on the experience that Allkem has in the execution of the Olaroz I and II projects, the country context, and the delays in certain types of materials. A detailed long lead items (LLI) must be made and include, beyond the main equipment, those components that today their manufacture plays an important role due to the scarcity of raw materials for their manufacture.
A geotechnical investigation of the identified evaporation pond area will confirm its suitability for construction.
The early design, application and rerouting of national road Route 70 will reduce permitting risk for the project and can be completed independently of the project design progression.
Progression of the study to feasibility level is recommended.
23.3 | Market Studies |
Market analysis will continue to evolve during the project development phase. It is recommended that Allkem continue with ongoing market analysis and related economic sensitivity analysis.
Cauchari Lithium Brine Project
SEC Technical Report Summary
Risk factors and opportunities in technological advancements, competition and macroeconomic trends should be reviewed for relevancy prior to major capital investment decisions. Remaining abreast of lithium extraction technology advancements, and potential further test work or pilot plant work may provide opportunities to improve the Project economics.
It is recommended to further develop a diversified customer base and secure offtake agreements to support the next study phase and potential expansion.
23.4 | Project Costs and Financial Evaluation |
Allkem is currently constructing the Sal de Vida Stage 1 processing facility. Continued monitoring of costs and timelines can further enhance planning for Cauchari.
The Cauchari project was evaluated as a stand-alone green fields and current permitting applications reflect this approach. With the successful progression and operation of the closely located Olaroz Project, the project Capex and Opex estimates can be reviewed for synergistic opportunities during construction and operations that could improve overall Project Economics.
The risk of changes to government acts, regulations, tax regimes or foreign exchange regulation remains and must be reviewed upon enactment. Related risk and change management must be accurately reflected in the Project contingencies or expected economic performance.
