EXPLANATORY NOTE

This Amendment No. 1 on Form 10-Q/A (the “Amendment”) of Perpetua Resources Corp. (the “Company”) amends the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, originally filed with the Securities and Exchange Commission on May 13, 2022 (the “Original Form 10-Q”). This Amendment is being filed solely to replace the certification of the principal financial officer in Exhibit 32.2 with the correct certification. The correct certification was fully executed on May 13, 2022 and was in the Company's possession at the time of the filing of the Original Form 10-Q. However, the wrong certification was inadvertently filed as Exhibit 32.2 in the Original Form 10-Q due to printer error.

As required by Rule 12b-15 under the Securities Exchange Act of 1934, the Exhibit Index in Item 6 of Part II of the Original Report is hereby amended to include currently dated certificates of the Company's principal executive officer and principal financial officer as exhibits to this Amendment No. 1. For the convenience of the reader, we have included all items in this Amendment which supersedes in its entirety the Original Form 10-Q.

Except as described above, this Amendment does not modify or update the other disclosures or exhibits in the Original Form 10-Q. Except as presented in this Form 10-Q/A and except for Exhibits 31.1, 31.2, 32.1 and 32.2 filed herewith, this Amendment No. 1 on Form 10-Q/A does not reflect events occurring after the filing of the Original Form 10-Q. Accordingly, this Amendment No. 1 on Form 10-Q/A should be read in conjunction with the Original Form 10-Q and the registrant’s other filings with the SEC subsequent to the date of the Original Form 10-Q.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this Quarterly Report are “forward-looking statements” within the meaning of “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995 and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”) and “forward-looking information” within the meaning of applicable Canadian securities laws. All statements, other than statements of historical fact included in this Quarterly Report, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this Quarterly Report, the words “anticipate,” “believe,” “expect,” “estimate,” “intend,” “plan,” “project,” “outlook,” “may,” “will,” “should,” “would,” “could,” “can,” the negatives thereof, variations thereon and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Forward-looking statements are based on certain estimates, beliefs, expectations and assumptions made in light of management’s experience and perception of historical trends, current conditions and expected future developments, as well as other factors that may be appropriate.

Forward-looking statements necessarily involve unknown risks and uncertainties, which could cause actual results or outcomes to differ materially from those expressed or implied in such statements. Due to the risks, uncertainties and assumptions inherent in forward-looking information, you should not place undue reliance on forward-looking statements. Factors that could have a material adverse effect on our business, financial condition, results of operations and growth prospects can be found in Item 1A, Risk Factors, Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations and elsewhere in this Quarterly Report and in Item 1A, Risk Factors and Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2021. These factors include, but are not limited to, the following:

Statements concerning mineral resource and mineral reserve estimates may also be deemed to constitute forward-looking information to the extent that such statements involve estimates of the mineralization that may be encountered if a property is developed.

With respect to forward-looking information contained herein, the Company has applied several material factors or assumptions including, but not limited to, certain assumptions as to production rates, operating cost, recovery and metal costs; that any additional financing needed will be available on reasonable terms; the exchange rates for the U.S. and Canadian currencies will be consistent with the Company’s expectations; that the current exploration, development, environmental other objectives concerning the Company’s Stibnite Gold Project (the “Project” or “Stibnite Gold Project”) can be achieved and that the Company’s other corporate activities will proceed as expected; that the formal review process under the National Environmental Policy Act (“NEPA”) (including a joint review

process involving the United States Forest Service (“USFS” or “Forest Service”), the State of Idaho and other agencies and regulatory bodies) as well as the public comment period and environmental impact statements will proceed in a timely manner and as expected; that the progression of the litigation involving the Nez Perce Tribe will proceed in a timely manner and as expected; that the current price and demand for gold and other metals will be sustained or will improve; that general business and economic conditions will not change in a materially adverse manner and that all necessary governmental approvals for the planned exploration, development and environmental protection activities on the Project will be obtained in a timely manner and on acceptable terms; and that the continuity of economic and political conditions and operations of the Company will be sustained.

These risks are not exhaustive. Because of these risks and other uncertainties, our actual results, performance or achievement, or industry results, may be materially different from the anticipated or estimated results discussed in the forward-looking statements in this Quarterly Report. New risk factors emerge from time to time, and it is not possible for our management to predict all risk factors nor can we assess the effects of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in, or implied by, any forward-looking statements. Our past results of operations are not necessarily indicative of our future results. You should not rely on any forward-looking statements, which represent our beliefs, assumptions and estimates only as of the dates on which they were made, as predictions of future events. We undertake no obligation to update these forward-looking statements, even though circumstances may change in the future, except as required under applicable securities laws. We qualify all of our forward-looking statements by these cautionary statements.

3.Mineral Properties and Interest

The Company’s mineral properties and interest at the Stibnite Gold Project totaled $72,204,334 as of both March 31, 2022 and December 31, 2021.

The Company’s subsidiaries acquired mineral rights to the Stibnite Gold Project through several transactions. All mineral rights held by the Company’s subsidiaries are held through patented and unpatented mineral and mill site claims, except the Cinnabar option claims which are held under an Option to Purchase (“OTP”), and all of the Stibnite Gold Project is subject to a 1.7% net smelter returns royalty upon the sale of project-related production.

Included in mineral properties and interest are annual payments made under option agreements, where the Company is entitled to continue to make annual option payments or, ultimately, purchase certain properties. Annual payments due under option agreements during 2022 are $180,000.

As of March 31, 2022, it has not yet been determined that the Project’s mining deposits can be economically and legally extracted or produced because the Project’s estimated reserves do not yet meet the definition of proven reserves under the United States Securities and Exchange Commission (“SEC”) Regulation S-K 1300.

Accordingly, development costs related to such reserves will not be considered capitalized unless they are incurred after such determination. Upon commencement of commercial production, capitalized costs will be amortized over their estimated useful lives or units of production, whichever is a more reliable measure.

Although the Company has taken steps to review and verify mineral rights to the properties in which it has an interest, in accordance with industry standards for properties in the exploration stage, these procedures do not guarantee the Company’s title and interests. Mineral title may be subject to unregistered prior agreements and noncompliance with regulatory requirements.

​

4.Warrant Derivative

In May 2013, the Company issued to Franco Nevada Company (“Franco”) 200,000 share purchase warrants (“Franco Warrants”) for gross proceeds of $350,000. The Franco Warrants are exercisable into 200,000 common shares of the Company at C$12.30 per warrant. The Franco Warrants contain a mandatory conversion feature which requires Franco to exercise 100% of the outstanding warrants if, at any time, the volume weighted average trading price of the Corporation’s common shares is equal to or greater than C$32.30 for a period of 30 consecutive trading days. The Franco Warrants expire on May 9, 2023.

The exercise price of the Franco Warrants is denominated in Canadian dollars; however, the functional currency of the Company is the U.S. dollar. As a result of this difference in currencies, the proceeds that will be received by the Company are not fixed and will vary based on foreign exchange rates and the warrants are a derivative and are required to be recognized and measured at fair value at each reporting period. Any changes in fair value from period to period are recorded as a gain or loss in the unaudited condensed consolidated statements of operations. There are no circumstances in which the Company would be required to pay any cash upon exercise or expiry of the warrants.

A reconciliation of the change in fair values of the derivative is below:

​

The fair value of the warrants was calculated using the Black-Scholes valuation model. As of March 31, 2022 and 2021, the inputs used in the Black-Scholes valuation model are:

​

​

​

​

5.Convertible Notes

On March 17, 2016, the Company issued unsecured convertible notes (the “2016 Notes”) for gross proceeds of $38.5 (C$50.0) million and a maturity date of March 17, 2023. On March 17, 2020, the Company issued a second round of unsecured convertible notes (the “2020 Notes”) for gross proceeds of $35.0 (C$47.6) million and a maturity date of March 17, 2027. The holders of the convertible notes may convert any portion of their convertible notes at any time prior to the maturity date into common shares of the Company, at a price of C$3.541 per share for the 2016 Notes and a price of C$4.655 for the 2020 Notes.

Each set of convertible notes are deemed to contain an embedded derivative (collectively, the “Convertible Note Derivatives”) relating to the conversion option. The Convertible Note Derivatives were valued upon initial recognition at fair value using partial differential equation methods. At inception, for each set of notes, the face value of the notes was reduced by the estimated fair value of the related convertible note derivative and the transaction costs.

During the years ended December 31, 2021 and 2020, convertible notes in the aggregate principal amount of C$15,409,901 and C$82,102,500, respectively were converted for 4,351,850 and 19,969,280 common shares of the Company, respectively. As of March 31, 2022 and December 31, 2021, the Corporation has no outstanding convertible notes.

​

​

​

6.Convertible Note Derivative

Convertible Note Derivatives related to each set of convertible notes (see Note 5) were valued upon initial recognition at fair value using partial differential equation methods and are subsequently re-measured at fair value at each period end through the unaudited condensed consolidated statements of operations. During the three month period ended March 31, 2021, a change in fair value of $11,596,790 was recognized for the convertible note derivative.

In 2021, the Convertible Note Derivatives expired upon conversion of all convertible notes (see Note 5).   The balance of the derivative at December 31, 2021 and March 31, 2022 is nil.

7.Equity

On January 27, 2021, the Corporation completed a one-for-ten (1:10) reverse share split of all of its issued and outstanding common shares (“Share Consolidation”), resulting in a reduction of the issued and outstanding common shares from 475,227,060 to 47,522,706. The number of shares reserved under the Corporation’s equity and incentive plans were adjusted to reflect the Share Consolidation. All share, per share data, and warrant and option exercise prices presented in the Company’s consolidated financial statements have been retroactively adjusted to reflect the Share Consolidation unless otherwise noted.

Share based compensation was recognized in the unaudited condensed consolidated statements of operations for the three month periods ended March 31, 2022 and 2021 as follows:

​

​

Share purchase options

A summary of share purchase option activity within the Company’s share-based compensation plan (the “Plan”) for the year ended December 31, 2021 and three month period ended March 31, 2022 is as follows:

​

​

During the three month periods ended March 31, 2022 and 2021, the Company’s total share based compensation from options was $252,900 and $1,933,519, respectively.

​

No options were granted during the three month period ended March 31, 2022. The grant date fair value of options granted during the three month period ended March 31, 2021 was approximately $4.9 million. The fair value of options granted is estimated at the time of the grant using the Black-Scholes option pricing model. The Company uses the Black-Scholes option valuation model.  The risk-free interest rate is based on the government security rate with an equivalent term in effect as of the date of grant.  The expected option lives and volatility assumptions are based on historical data of the Company.  The weighted

average inputs used in the Black-Scholes option pricing model for options granted during the three month period ended March 31, 2021 are:

​

​

An analysis of outstanding share purchase options as of March 31, 2022 is as follows:

​

¹   Weighted Average Exercise Price (C$)

²   Weighted Average Remaining Contractual Life (Years)

As of March 31, 2022, all unvested options are expected to vest and unvested compensation of approximately $1.3 million will be recognized. The weighted average remaining period of vesting options is 1.2 years. As of March 31, 2022, the intrinsic value of outstanding and exercisable share purchase options is $71,259 and $42,927, respectively. During the three month periods ended March 31, 2022 and 2021, the intrinsic value of share purchase options exercised was nil and $432,153 respectively.

During the three month period ended March 31, 2022, the Company awarded 330,098 RSUs that had a weighted average grant date fair value of $4.03 per RSU or approximately $1.3 million in total.

During the three months ended March 31, 2022, the Company has recognized $110,740 in compensation expense related to RSUs and expects to record an additional $1.4 million in compensation expense over the next 1.9 years. There was no

13

Table of Contents

compensation expense for RSUs recorded during the three month period ended March 31, 2021.   The unvested units at March 31, 2022 are scheduled to vest as follows:

​

​

Unvested units will be forfeited by participants upon termination of employment in advance of vesting, with the exception of termination due to retirement if certain criteria are met.

​

During the three months ended March 31, 2022, the Company has recognized $55,666 in compensation expense related to PSUs and MPSUs and expects to record an additional $1.75 million in compensation expense over the next 2.8 years. The PSUs and MPSUs are scheduled to vest as follows: 7,250 awards in September 2022, 7,500 awards in September 2023, and 249,533 in March 2025. There was no compensation expense for PSUs and MPSUs recorded during the three-month period ended March 31, 2021.

PSUs: These PSUs vest upon completion of the performance period (through September 2022 and 2023) and specific performance conditions set forth for each individual grant for individually defined reporting and operating measurement objectives. The Company determines the factor to be applied to that target number of PSUs, with such percentage based on level of achievement of the performance conditions.  Upon the achievement of the conditions, any unvested PSUs become fully vested.  During the three month period ended March 31, 2022, the Company awarded 7,500 PSUs that had a weighted average grant date fair value of $4.03 per PSU, or $30,225 in total.  

Market-based PSUs: On March 5, 2022, the Company granted MPSUs where vesting is based on the Company’s cumulative total shareholder return (“TSR”) as compared to the constituents that the comprise the VanEck Junior Gold Miners ETF (“GDXJ Index”) a group of similar junior gold mining companies, over the period from March 5, 2022 to March 5, 2025 (the “Performance Period”). The ultimate number of MPSUs that vest may range from 0% to 200% of the original target number of shares depending on the relative achievement of the TSR performance measure at the end of the Performance Period.  Because the number of MPSUs that are earned will be based on the Company’s TSR over the Performance Period, the MPSUs are considered subject to a market condition. Compensation cost is recognized ratably over the Performance Period regardless as to whether the market condition is actually satisfied; however, the compensation cost will reverse if an employee terminates prior to satisfying the requisite service period.

During the three month period ended March 31, 2022, the Company awarded 249,533 MPSUs that had a weighted grant date fair value of $6.99 per MPSU or approximately $1.75 million in total.   The grant date fair value of MPSUs was estimated using a Monte Carlo simulation model. Assumptions and estimates utilized in the model include expected volatilities of the Corporation’s stock and the GDXJ Index, the Company’s risk-free interest rate and expected dividends. The probabilities of the actual number of MPSUs expected to vest and resultant actual number of shares of common stock expected to be awarded

14

Table of Contents

are reflected in the grant date fair values of the various MPSU awards.  The per MPSU grant date fair value of $6.99 for the market condition was based on the following variables:

​

​

The expected volatility utilized is based on the historical volatilities of the Corporation’s common stock and the GDXJ Index in order to model the stock price movements. The volatility used was calculated over the most recent three year period. The risk-free interest rates used are based on the implied yield available on a U.S. Treasury zero-coupon bill with a term equivalent to the Performance Period. The expected dividend yield of zero was used since it is the mathematical equivalent to reinvesting dividends in each issuing entity over the Performance Period.

Under the Plan, the Company may issue DSUs to non-employee directors.  During the three month period ended March 31 2022, 62,669 shares with a fair value of $256,943 were granted to the non-employee directors and the related compensation expense was charged to directors’ fees in the unaudited condensed consolidated statements of operations.  There was no compensation expense for DSUs recorded during the three-month period ended March 31, 2021.

There was a total of 200,000 warrants outstanding as of March 31, 2022. See Note 4.

​

8.Financial Instruments and Fair Value Measurements

At March 31, 2022, the Company’s financial instruments consist of cash and cash equivalents and environmental reclamation bond which approximate their fair value due to their short-term nature.  

The Company’s financial instruments also consist of the warrant derivative at March 31, 2022 and December 31, 2021. The derivative is valued at fair value at the end of each reporting period. At March 31, 2022 and December 31, 2021, the levels in the fair value hierarchy into which the Company’s financial assets and liabilities are measured and recognized on the balance sheet at fair value are categorized as follows:

​

​

​

15

Table of Contents

The Company uses the Black-Scholes option pricing model or other valuation models for valuation of its warrant derivative. Valuation models require the input of subjective assumptions including expected share price volatility, interest rate and forfeiture rate. Changes in the input assumptions can materially affect the fair value estimate and the Company's net loss.

​

9.Environmental Reclamation Liability

On January 15, 2021, the Company agreed to an Administrative Settlement and Order on Consent (“ASAOC”). The Company has accounted for its obligation under the ASAOC as an environmental reclamation liability. The aggregate cost of the obligation was estimated to be approximately $7,473,805. Upon the signing of the ASAOC, the Company recorded an immediate expense of $7,473,805 and a corresponding environmental reclamation liability. The provision for the liability associated with the terms of the ASAOC is based on cost estimates developed with the use of engineering consultants, independent contractor quotes and the Company’s internal development team. The timing of cash flows is based on the latest schedule for early action items. The estimated environmental reclamation liability may be subject to change based on changes to cost estimates and is adjusted for actual work performed. Movements in the environmental reclamation liability during the quarter ended March 31, 2022, are as follows:

​

​

The Company provided $7.5 million in financial assurance for Phase 1 projects under the ASAOC. The Company paid $3.0 million in cash collateral for a surety bond related to the ASAOC statement of work in early 2021.

​

10.Commitments and Contingencies

The Company currently holds mining claims on which it has an annual assessment obligation to the Bureau of Land Management of $250,470 to maintain the claims in good standing. The Company is committed to these payments indefinitely. Related to the mining claims assessments is a $335,000 bond related to the Company’s exploration activities.

Upon formation of the Stibnite Foundation on February 26, 2019, the Company became contractually liable for certain future payments to the Stibnite Foundation based on several triggering events, including receipt of a final Record of Decision issued by the USFS, receipt of all permits and approvals necessary for commencement of construction, commercial production, and of the final reclamation phase.  These payments could begin as early as late 2023 based on the current permitting schedule and range from $0.1 million to $1 million (upon commencement of final reclamation phase) in cash and 150,000 shares of the Corporation’s common stock. During commercial production, the Company will make payments to the Stibnite Foundation equal to 1% of Total Comprehensive Income less debt repayments, or a minimum of $0.5 million each year.

The Stibnite Foundation will support projects that benefit the communities surrounding the Stibnite Gold Project and was created through the establishment of the Community Agreement between Perpetua Resources Idaho, Inc. and eight communities and counties throughout the West Central Mountains region of Idaho.

The Company is obligated to make option payments on mineral properties in order to maintain an option to purchase these properties. As of March 31, 2022, the option payments due on these properties in 2022 are $180,000, which will be paid in the next year. The agreements include options to extend.

The Company has no off-balance sheet arrangements as of March 31, 2022 and the date of this report.

e.Legal Update

The Company is a party to ongoing legal proceedings with the Nez Perce Tribe for alleged violations of the Clean Water Act related to historical mining activities. In August 2019, the Nez Perce Tribe filed suit in the United States District Court for the District of Idaho. The Company promptly filed a motion to dismiss and, in the alternative, a motion to stay the litigation. Both motions were denied. Later, the court allowed the Company to amend its answer and file a third-party complaint and the Company also filed a separate citizen suit against the USFS alleging the point source discharges, referred to by the Nez Perce Tribe in its complaint, were alleged to be occurring on lands owned and controlled by the United States. Pursuant to the terms of the Comprehensive Environmental Response, Compensation, and Liability Act (the “CERCLA”) ASAOC executed with the U.S. EPA and the United States Department of Agriculture, the Company dismissed its pending actions against USFS. The remaining parties to the ongoing legal proceeding agreed to stay the litigation and explore Alternative Dispute Resolution (“ADR”) options. The stay has been extended on subsequent occasions, and a request to extend the stay through July 31, 2022 was filed jointly by the parties on April 28, 2022 and subsequently ordered by the court on April 29, 2022.

The CERCLA ASAOC entered into by the Company, the U.S. EPA, and the United States Department of Agriculture requires numerous voluntary early cleanup actions to occur over the next several years. Perpetua Resources Idaho, Inc. is presently executing the development of the Phase 1 early cleanup actions (known as “time critical removal actions”) that, upon final work plan approval by the federal agencies, will be designed and constructed to efficiently improve water quality in a number of areas on the Site while other, longer-term proposed actions relating to Project operations are being evaluated through the NEPA process.

Recent Key Developments

2022 Outlook and Goals

Perpetua Resources’ vision is to provide the United States with a domestic source of the critical mineral antimony, develop one of the largest and highest-grade open pit gold mines in the country and restore an abandoned brownfield site. In 2022, Perpetua Resources continues to focus on advancing the permitting for the Stibnite Gold Project through the National Environmental Policy Act (“NEPA”) process. The NEPA process is intended to ensure that federal agencies and the public are informed of a proposed action’s potential environmental impacts before a final decision is made by the agency regarding the action.

In response to public comments received on the Draft Environmental Impact Statement (“DEIS”), Perpetua Resources submitted a refined proposed action to the USFS in December 2020. To ensure a full analysis of the improved Project, the USFS will issue a Supplemental Draft Environmental Impact Statement (“SDEIS”) followed by an opportunity for public comment. The preliminary SDEIS was circulated for cooperating agency review in April 2022. The publication of the SDEIS for public review and comment is expected in early third quarter 2022. The USFS is expected to provide a formal schedule later this year regarding the remaining steps in the NEPA review process.

First Quarter 2022 Highlights

The forward‐looking information contained in this section is subject to the risk factors and assumptions contained in the “Cautionary Note Regarding Forward-Looking Statements” and “Risks Factor” sections.

Table of Contents

Net Loss

Net loss for the three months ended March 31, 2022 was $6.2 million compared with a net loss of $4.7 million for the three months ended March 31, 2021. This $1.5 million increase compared to the prior year period was primarily attributable to a $11.6 million decrease in the gain related to the change in fair value of the convertible note derivative, a $0.5 million decrease in the gain related to the change in fair value of the warrant derivative and a $0.6 million increase in professional fees. These changes were partially offset by a $7.5 million decrease in environmental liability expense, a $2.0 million decrease in exploration expenses, and a $0.6 million decrease in corporate salaries and benefits.  As noted above, for the three months ended March 31, 2022, the Company’s main focus was the continued evaluation and advancement of the Stibnite Gold Project.

Consulting

This expense relates to consulting services provided to the Corporation that do not relate to the exploration and evaluation of the Stibnite Gold Project. Consulting fees for the three months ended March 31, 2022 are 90% lower than the previous year due to consulting work to support various corporate activities in the first quarter of 2021, including the share consolidation and listing on the NASDAQ.

Corporate Salaries and Benefits

This expense results from salaries and benefits of the employees that are not directly related to the exploration and evaluation of the Stibnite Gold Project, primarily corporate employees. Salaries and benefits for the three months ended March 31, 2022 were $0.6 million, or 66%, lower than the previous year primarily due to severance payments made to corporate employees in the first quarter of 2021 and lower stock-based compensation.

Directors’ Fees

Each of the Corporation’s non-executive directors is entitled to annual base fees paid in quarterly installments, with the independent Lead Director, Chairs of Board Committees and Members of Board Committees receiving additional fees commensurate with each role. Directors’ fees are inclusive of cash fees and share-based compensation (deferred share units and stock options). This

19

Table of Contents

expense for the three months ended March 31, 2022, is $41,263, or 14%, lower than the previous year primarily due to the number of stock options vesting in the first quarter of 2021.

Exploration

This expense relates to all exploration and evaluation expenditures related to the Stibnite Gold Project, including labor, drilling, field operations costs, engineering, permitting, environmental, legal and sustainability costs. The Company’s exploration expenses of $4.6 million during the three months ended March 31, 2022 are $2.0 million, or 31%, lower than the three months ended March 31, 2021 primarily due to a $1.4 million decrease in consulting and labor cost including lower stock based compensation expense, a $0.5 million decrease in permitting, and a $0.2 million decrease in engineering partially offset by a $0.3 million increase in legal and sustainability. Additional details of expenditures incurred are as follows:

​

Environmental Liability Expense

This expense relates to the ASAOC signed in January 2021 to voluntarily address environmental conditions at the abandoned mine site. Upon signing of the ASAOC, the Company recorded an immediate expense of $7,473,805 and a corresponding environmental reclamation liability. Cost estimates were developed with the use of engineering consultants, independent contractor quotes and the Company’s internal development team, and the timing of cash flows is based on the current schedule for early action items. In the three months ended March 31, 2022, the total cost estimate to complete Phase 1 early cleanup actions did not change. As of March 31, 2022, the estimate for the environmental liability was $9.4 million.

Office and Administrative

This expense is predominantly insurance policies for the U.S. offices and is $258,785, or 55%, lower for the three months ended March 31, 2022, than the three months ended March 31, 2021 primarily due to lower insurance premiums.

Professional Fees

This expense relates to the legal and accounting costs of the Corporation. The costs for the three months ended March 31, 2022 were $567,193, or 339%, higher than the three months ended March 31, 2021 primarily due to legal fees to support the Company’s transition to a U.S. Domestic Issuer and increased accounting fees related to the change in the basis of accounting for the Company’s consolidated financial statements from international standards to U.S. GAAP.

Shareholder and Regulatory

This expense relates to marketing, licenses and fees, and shareholder communications. The expense for the three months ended March 31, 2022 is $92,562, or 37%, lower than the three months ended March 31, 2021 primarily due to fees related to the NASDAQ listing which commenced in February 2021.

Change in Fair Value of Warrant Derivative

The Corporation issued 200,000 warrants in a financing transaction in May 2013, with an exercise price denominated in Canadian dollars. The Company determined that warrants with an exercise price denominated in a currency that is different from the entity’s functional currency should be classified as a derivative and carried at their fair value. Any changes in their fair value from period to period have been recorded as a gain or loss. There are no circumstances under which Perpetua Resources will be required to pay cash upon exercise or expiry of the warrants or finder’s options (see Note 4 in the Condensed Consolidated Financial Statements - unaudited).

Change in Fair Value of Convertible Note Derivative

The Corporation issued unsecured convertible notes with an interest rate of 0.05% per annum in March 2016 and March 2020 (together, the “Convertible Notes”) with an exercise price denominated in Canadian dollars. The Company determined that the Convertible Notes with an exercise price denominated in a currency that is different from the entity’s functional currency should be classified as a derivative and carried at their fair value. Any changes in their fair value from inception to balance sheet date have been recorded as a gain or loss in the Consolidated Statements of Operations. The convertible note derivative is valued at fair value. The decrease in fair value is due to the conversion of Convertible Notes during the year. During 2021, the remaining Convertible Notes in the aggregate principal amount of C$15,409,901 were converted for 4,351,850 common shares of Perpetua Resources at a conversion rate of C$3.541 per common share (see Note 4 in the Condensed Consolidated Financial Statements - unaudited).

Finance Costs

Finance costs for the Corporation include accretion of note discount and interest expense related to the Convertible Notes described above. No such expense was recognized for the three months ended March 31, 2022 given the remainder of the Convertible Notes were converted in 2021.

Foreign Exchange Loss

Changes in foreign exchange are driven by the change in value of the Canadian Dollar compared to the U.S. Dollar and the impact the change has on translating the Corporation’s Canadian dollar denominated balances. The impact was larger in the first quarter of 2021 compared to the first quarter of 2022 primarily due to the translation on the Convertible Notes and convertible note derivatives which were fully converted in 2021.

Interest Income

This income results from interest received on the Company’s cash balances. Interest income increased $7,572 in the three months ended March 31, 2022, compared to the three months ended March 31, 2021 as a result of higher average cash balances in the first quarter of 2022.

Liquidity and Capital Resources

Capital resources of Perpetua Resources consist primarily of cash and liquid short-term investments. As of March 31, 2022, Perpetua Resources had cash and cash equivalents totaling approximately $41.2 million, approximately $1.0 million in other current assets and $2.0 million in trade and other payables.

In August 2021, the Corporation completed a public offering for total gross proceeds of $57.5 million to be used to continue permitting, early restoration and field operations, engineering and design and general corporate purposes.

With its current capital resources, Perpetua Resources believes that it has sufficient funds to continue to advance the regulatory process related to permitting for mine development beyond 2022. Perpetua Resources plans to:

It is management’s opinion, based on the Corporation’s current capital resources and liquidity that the Corporation will have sufficient assets to discharge its liabilities as they become due, to continue to advance the Stibnite Gold Project for at least 12 months from the date these first quarter 2022 financial statements are issued, and to meet its administrative and overhead requirements for more than a year. Future financings to fund construction are anticipated through debt, equity, project specific debt, and/or other means. Our continued operations are dependent on our ability to obtain additional financing or to generate future cash flows. However, there can be no assurance that we will be successful in our efforts to raise additional capital on terms favorable to us, or at all.

Our anticipated expenditures in fiscal year 2022 are approximately $27.5 million, which are expected to be funded from cash on hand. These expenditures include an estimated $12.2 million to fund permitting of the Stibnite Gold Project, $10.5 million for general corporate purposes and administrative costs, $0.7 million for engineering and design work and $4.1 million to advance early restoration and continue field operations. These costs are subject to change due to cost over-runs, delays or other unbudgeted events.
