PRELIMINARY JOINT PROXY STATEMENT/PROSPECTUS — SUBJECT TO COMPLETION, DATED APRIL 7, 2020

JOINT PROXY STATEMENT/PROSPECTUS FOR SPECIAL MEETING OF MUDRICK CAPITAL ACQUISITION CORPORATION AND SPECIAL MEETING OF HYCROFT MINING CORPORATION

PROSPECTUS FOR
16,849,092 SHARES OF CLASS A COMMON STOCK

The board of directors of Mudrick Capital Acquisition Corporation (the “MUDS Board”), a Delaware corporation (“MUDS,” the “Company,” “we,” “us” or “our”) has approved (a) the purchase agreement, dated as of January 13, 2020 and amended on February 26, 2020 (as it may be further amended from time to time, the “Purchase Agreement”), by and among MUDS, MUDS Acquisition Sub, Inc., a Delaware corporation and an indirect, wholly-owned subsidiary of MUDS (“Acquisition Sub”) and Hycroft Mining Corporation, a Delaware corporation (“Seller”), pursuant to which (i) Acquisition Sub will acquire from Seller the issued and outstanding equity interests of Allied Nevada Gold Holdings, LLC, a Nevada limited liability company (“Nevada Gold”), Allied VGH Inc., a Nevada corporation (“Allied VGH”) and Allied Nevada Delaware Holdings Inc., a Delaware corporation (“Allied Delaware” and, together with Nevada Gold and Allied VGH, the “Hycroft direct subsidiaries”), the direct subsidiaries of Seller, and MUDS or Acquisition Sub will acquire substantially all of the assets and assume substantially all of the liabilities of Seller (such equity interests and assets and liabilities together, the “Hycroft business”) in exchange for (x) shares of HYMC Class A common stock (as defined herein) and (y) the 1.5 Lien Notes and the Excess Notes, if any (each as defined herein), (ii) Seller will promptly distribute all of the shares of HYMC Class A common stock it receives to its stockholders pro rata (the “distribution”) and (iii) the parties will consummate the other transactions contemplated thereby, including (x) the assumption by MUDS of (A) up to $80,000,000 in aggregate principal amount of Seller’s New Subordinated Notes (as defined herein) (the “Assumed New Subordinated Notes”), (B) Seller’s obligations under the Sprott Credit Agreement (as defined herein) and (C) Seller’s liabilities and obligations under the Seller Warrant Agreement (as defined herein) (collectively, the “debt and warrant assumption”) and (y) the payoff of certain outstanding indebtedness of Seller, including the First Lien Credit Agreement and the Jacobs Note (each as defined herein) (such amount, the “payoff amount”), on the terms and subject to the conditions set forth therein, (b) the exchange agreement, dated as of January 13, 2020 (the “Exchange Agreement”), by and among Seller, Acquisition Sub, the 1.25 Lien Noteholders (as defined herein) and the 1.5 Lien Noteholders (as defined herein), pursuant to which Acquisition Sub will acquire any New Subordinated Notes in excess of the Assumed New Subordinated Notes (such notes, the “Excess Notes”) and the issued and outstanding 1.5 Lien Notes (as defined herein) (the “exchange”), and (c) the conversion and consent agreement, dated as of January 13, 2020 (the “Second Lien Conversion Agreement”), by and among Seller and all of the Second Lien Noteholders (as defined herein), pursuant to which the Second Lien Noteholders have agreed to convert their Second Lien Notes (as defined herein) into shares of Seller common stock (the “conversion,” and all of the transactions described in the foregoing clauses (a) — (c) in the order provided for in the Purchase Agreement and the Exchange Agreement and the Second Lien Conversion Agreement, together, the “business combination”). Copies of the Purchase Agreement and the Exchange Agreement are attached to this joint proxy statement/prospectus as Annex A and Annex B, respectively. In connection with the consummation of the business combination, MUDS will change its name to “Hycroft Mining Holding Corporation.” We refer to MUDS following the consummation of the business combination as “HYMC.”

Upon effectiveness of the business combination, HYMC’s issued and outstanding share capital will consist of, assuming the separation of all public units (as defined herein) into shares and warrants: (A) up to 16,849,092 shares of Class A common stock, par value $0.0001 per share (“HYMC Class A common stock”), issued to Seller and distributed to Seller’s stockholders in the business combination (the “purchase shares”), (B) up to 3,258,333 shares of HYMC Class A common stock, which shares shall have converted from an equal number of shares of MUDS Class B common stock in accordance with the terms of the Amended and Restated Certificate of Incorporation of MUDS, as amended, in effect immediately prior to the consummation of the business combination and the Parent Sponsor Letter Agreement, dated as of January 13, 2020, by and between MUDS and Mudrick Capital Acquisition Holdings LLC (“sponsor”), (C) up to 19,534,242 shares of HYMC Class A common stock issued to the holders of the Excess Notes and the 1.5 Lien Notes in the exchange, (D) (x) up to 6,500,000 shares of HYMC Class A common stock issued pursuant to (i) the Subscription/Backstop Agreements, each dated as of January 13, 2020, by and between the Initial Subscribers (as defined herein) and MUDS and/or (ii) such other subscription agreements with certain Third-Party Private Investors (as defined herein) and (y) 3,250,000 warrants (the “PIPE warrants”) to purchase one share of HYMC Class A common stock for $11.50 per share issued to the Initial Subscribers pursuant to the Subscription/Backstop Agreements, in each case, in a private placement offered to a limited number of accredited investors (as defined by Rule 501 of Regulation D) pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “private investment”), (E) up to 2,000,000 shares of HYMC Class A common stock issued in connection with an incremental equity investment in an aggregate amount of up to $20,000,000, (F) up to 6,909,287 shares of HYMC Class A common stock, representing outstanding shares held by MUDS public stockholders and not redeemed in connection with the business combination (assuming no redemption of MUDS Class A common stock (as defined herein) in connection with the business combination), (G) 20,800,000 outstanding warrants to purchase one share of HYMC Class A common stock for $11.50 per share (“public warrants”), (H) 625,000 shares of HYMC Class A common stock (the “forward purchase shares”) and 2,500,000 units (the “forward purchase units”), each such unit comprised of one share of HYMC Class A common stock and one warrant to purchase one share of HYMC Class A common stock for $11.50 per share, issued to sponsor in connection with the transactions contemplated by the Forward Purchase Contract, dated as of January 24, 2018, by and between MUDS and sponsor, (I) 6,700,000 warrants to purchase one share of HYMC Class A common stock (the “sponsor private placement warrants”) issued to sponsor, pursuant to the Private

TABLE OF CONTENTS

Placement Warrants Purchase Agreement, dated as of January 15, 2018, by and between MUDS and sponsor, (J) 1,040,000 warrants to purchase one share of HYMC Class A common stock (the “Cantor private placement warrants” and, together with the sponsor private placement warrants, the “private placement warrants”) issued to Cantor Fitzgerald & Co. (“Cantor”), pursuant to the Private Placement Warrant Purchase Agreement, dated as of January 16, 2018, by and between MUDS and Cantor, (K) restricted stock units convertible into shares of HYMC Class A common stock valued at no more than $4,277,000 received in connection with the business combination in exchange for restricted stock units convertible into shares of Seller common stock, (L) up to 478,000 shares of HYMC Class A common stock issued to Cantor as partial payment of Cantor’s deferred underwriting commission (the “underwriting commission issuance”), pursuant to the Underwriting Agreement, dated as of February 7, 2018, as amended on February 12, 2020, by and among MUDS and Cantor, as representative of the several underwriters (the “UA Amendment” and together with the Underwriting Agreement, the “Amended Underwriting Agreement”), (M) a number of shares of HYMC Class A common stock equal to 1% of the total number of shares of HYMC Class A common stock outstanding immediately after the consummation of the business combination which shall be issued to Lender (as defined herein) pursuant to the Sprott Credit Agreement (the “lender issuance”) and (N) up to 12,721,623 Seller warrants (as defined herein) assumed by HYMC in the business combination, which as of April 1, 2020 were each exercisable into 2.212 shares of Seller common stock at a price of $5.07 per share, and will become exercisable following consummation of the business combination to purchase shares of HYMC Class A common stock, subject to an equitable adjustment of both the exercise price and number of shares of HYMC Class A common stock into which such Seller warrants will be exercisable. The Seller warrants are currently out-of-the money as the exercise price of $5.07 per share is substantially higher than the value attributable to the shares of Seller common stock in the business combination, which, based upon the foregoing assumptions of outstanding shares of Seller common stock (including an assumed conversion of the Second Lien Notes) as of April 30, 2020, is estimated to range from approximately $1.12 per share in the no redemption scenario to approximately $1.23 per share in the maximum redemption scenario.

MUDS’ publicly-traded units, Class A common stock and warrants are currently listed on the NASDAQ Capital Market (“NASDAQ”) under the symbols “MUDSU”, “MUDS” and “MUDSW”, respectively. MUDS intends to apply to continue the listing of its publicly-traded Class A common stock and public warrants, to be effective upon the consummation of the business combination, on NASDAQ under the proposed symbols “HYMC” and “HYMCW”, respectively. MUDS will not have units traded following consummation of the business combination.

As described in this joint proxy statement/prospectus, (i) MUDS’ stockholders are being asked to consider and vote upon (among other things) the proposed business combination, and (ii) Seller’s stockholders are being asked to consider and vote upon the proposed business combination.

Proposals to approve the business combination and other matters discussed in this joint proxy statement/prospectus will be presented at the special meeting of the stockholders of MUDS (the “MUDS special meeting”) scheduled to be held on [•], 2020.

Proposals to approve the Purchase Agreement and the plan of dissolution as discussed in this joint proxy statement/prospectus will be presented at the special meeting of the stockholders of Seller (the “Seller special meeting”) scheduled to be held on [•], 2020.

This joint proxy statement/prospectus provides stockholders of Seller with detailed information about the business combination and other matters to be considered at the Seller special meeting. We encourage you to carefully read this entire document and the documents incorporated herein by reference.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the transactions described in this joint proxy statement/prospectus, passed upon the fairness of the Purchase Agreement, the Exchange Agreement, the Second Lien Conversion Agreement or the transactions contemplated thereby, or passed upon the adequacy or accuracy of this joint proxy statement/prospectus.

The Charter Proposals — To consider and vote upon seven separate proposals to approve, assuming the Business Combination Proposal and the NASDAQ Proposal are approved and adopted, the following material differences between MUDS’ existing amended and restated certificate of incorporation, as amended (the “existing charter”) and the proposed second amended

TABLE OF CONTENTS

and restated certificate of incorporation (the “proposed charter”) of MUDS (which will be renamed “Hycroft Mining Holding Corporation” after consummation of the business combination and which is referred to herein as “HYMC” following the business combination).

Proposal No. 2 — To consider and vote upon an amendment to MUDS’ existing charter to increase the total number of authorized shares of all classes of capital stock from 111,000,000 shares to 410,000,000, which would consist of (a) 400,000,000 shares of Class A common stock and (b) 10,000,000 shares of preferred stock;

Proposal No. 3 — To consider and vote upon an amendment to MUDS’ existing charter to declassify the HYMC board of directors, so that each member of the HYMC board of directors will be elected at each annual meeting of stockholders, as opposed to MUDS having three classes of directors, with only one class of directors being elected in each year and each class serving a three-year term, and to make certain related changes;

Proposal No. 4 — To consider and vote upon an amendment to MUDS’ existing charter to provide that certain transactions are not “corporate opportunities” and that each of Mudrick Capital, Highbridge, Whitebox, Aristeia and Wolverine (as each is defined below) and the investment funds affiliated with or managed by Mudrick Capital, Highbridge, Whitebox, Aristeia and Wolverine and their respective successors and affiliates and all of their respective partners, principals, directors, officers, members, managers, equity holders and/or employees, including any of the foregoing who served as officers or directors of MUDS (each, an “Exempted Person”) are not subject to the doctrine of corporate opportunity in respect of MUDS;

Proposal No. 5 — To consider and vote upon an amendment to MUDS’ existing charter to permit stockholder action by written consent;

Proposal No. 6 — To consider and vote upon an amendment to MUDS’ existing charter to provide that HYMC will not be governed by Section 203 of the Delaware General Corporation Law (“DGCL”) and to approve a provision in the proposed charter that is substantially similar to Section 203 of the DGCL, but excludes the investment funds affiliated with sponsor and their respective successors and affiliates and the investment funds affiliated with or managed by Mudrick Capital, Whitebox, Highbridge, Aristeia and Wolverine and their respective successors and affiliates (the “Sponsor Holders”) from the definition of “interested stockholder,” and to make certain related changes. Upon consummation of the business combination, the Sponsor Holders will become “interested stockholders” within the meaning of Section 203 of the DGCL, but will not be subject to the restrictions on business combinations set forth in Section 203 of the DGCL, as the MUDS Board approved the business combination in which the Sponsor Holders became interested stockholders prior to such time as they became interested stockholders;

Proposal No. 7 — To consider and vote upon an amendment to MUDS’ existing charter to clarify that the exclusive forum provision adopting the Court of Chancery of the State of Delaware as the exclusive forum for certain stockholder litigation shall not apply to any action to enforce any liability or duty under the Securities Act or the Exchange Act for which there is exclusive federal or concurrent federal and state jurisdiction; and

Proposal No. 8 — To consider and vote upon an amendment to MUDS’ existing charter to authorize all other proposed changes, including, among others, those (i) resulting from the business combination, including changing the post-business combination corporate name from “Mudrick Capital Acquisition Corporation” to “Hycroft Mining Holding Corporation” and removing certain provisions relating to MUDS’ prior status as a blank check company and MUDS Class B common stock that will no longer apply upon consummation of the business combination, or (ii) that are administrative or clarifying in nature, including the deletion of language without substantive effect.

A copy of the Incentive Plan is attached to the accompanying joint proxy statement/prospectus as Annex C; and

The above matters are more fully described in the accompanying joint proxy statement/prospectus, which also includes as Annex A a copy of the Purchase Agreement. We urge you to read carefully the accompanying joint proxy statement/prospectus in its entirety, including the Annexes and the accompanying financial statements of MUDS and Seller.

The record date for the MUDS special meeting is [•], 2020. Only stockholders of record at the close of business on that date may vote at the MUDS special meeting or any adjournment thereof.

While all stockholders are cordially invited to attend the MUDS special meeting, due to the impact of the novel coronavirus disease COVID-19 and potential limitations on in person meetings, to ensure that as many shares as possible are represented, we strongly encourage you to vote in advance of the MUDS special meeting.

In addition, as part of our effort to maintain a safe and healthy environment at the MUDS special meeting and to protect the well-being of our stockholders, we are closely monitoring statements and guidance issued by the World Health Organization (who.int) and the Centers for Disease Control and Prevention (cdc.gov) regarding the novel coronavirus disease, COVID-19. While we currently intend to hold the MUDS special meeting in person, in the event it is not possible or if we determine it is inadvisable to hold the MUDS special meeting in person, we will announce alternative arrangements for the meeting as promptly as practicable, which may include holding the meeting by means of remote communication. If we do hold the MUDS special meeting in person, we may impose additional procedures or limitations on meeting attendees consistent with public health guidance. Any such updates (including if we decide to use remote communication) will be announced by press release and included in updated information filed by MUDS with the SEC, which would be available through the EDGAR system at www.sec.gov.

We are providing the accompanying joint proxy statement/prospectus and accompanying proxy card to MUDS’ stockholders in connection with the solicitation of proxies to be voted at the MUDS special meeting and at any adjournments of the MUDS special meeting. Information about the MUDS special meeting, the business combination and other related business to be considered by MUDS’ stockholders at the MUDS special meeting is included in this joint proxy statement/prospectus. Whether or not you plan to attend the MUDS special meeting, we urge all of MUDS’ stockholders to read the accompanying joint proxy statement/prospectus, including the Annexes and the accompanying financial statements of MUDS and Seller, carefully and in their entirety.

IN PARTICULAR, WE URGE YOU TO READ CAREFULLY THE SECTION ENTITLED “RISK FACTORS” BEGINNING ON PAGE [•] OF THE ACCOMPANYING JOINT PROXY STATEMENT/PROSPECTUS.

After careful consideration, the MUDS Board has approved the business combination and recommends that stockholders vote “FOR” adoption of the Purchase Agreement, the Exchange Agreement and the Second

TABLE OF CONTENTS

Lien Conversion Agreement and approval of the transactions contemplated thereby, including the business combination, and “FOR” all other proposals presented to MUDS’ stockholders in the accompanying joint proxy statement/prospectus. When you consider the MUDS Board’s recommendation of these proposals, you should keep in mind that MUDS’ directors and officers have interests in the business combination that may conflict with your interests as a stockholder. Please see the sections entitled “The Business Combination — Interests of Certain Persons in the Business Combination” and “Special Meeting of MUDS’ Stockholders — Recommendation to MUDS’ Stockholders” for additional information.

As a result of the business combination, MUDS and Acquisition Sub will acquire the Hycroft business. Subject to the terms of the Purchase Agreement, assuming consummation of the business combination on April 30, 2020, the value of the aggregate consideration in the business combination is expected to be approximately $613,600,000, which amount is inclusive of (i) the value of the HYMC Class A common stock being issued to Seller and distributed to Seller’s stockholders in the business combination (the “purchase shares”), (ii) the value of the Excess Notes and the 1.5 Lien Notes, (iii) the debt and warrant assumption and (iv) the payoff amount. The consideration to be paid to Seller will be comprised of (x) a number of shares of HYMC Class A common stock, equal to (1) (A) $325,000,000, plus (B) the value of the Surrendered Shares (as defined herein) valued at $10.00 per share, minus (C) the sum of the 1.5 Lien Share Payment Amount and the 1.5 Lien Cash Payment Amount (each as defined herein), minus (D) the sum of the Excess Notes Share Payment Amount and the Excess Notes Cash Payment Amount (each as defined herein), divided by (2) $10.00, and (y) the Excess Notes and the 1.5 Lien Notes. Promptly following the issuance of the purchase shares to Seller in connection with the business combination, Seller intends to distribute the purchase shares pro rata to its stockholders and Seller will cancel and retire the Excess Notes and 1.5 Lien Notes. See the section entitled “The Business Combination — Consideration to Seller Stockholders in the Business Combination” beginning on page [•] for further details. Copies of the Purchase Agreement and the Exchange Agreement are attached to the accompanying joint proxy statement/prospectus as Annex A and Annex B, respectively.

In connection with MUDS’ initial public offering (the “IPO”), the initial stockholders agreed to vote all shares of Class B common stock and any shares of Class A common stock purchased during or after the IPO in favor of the business combination. Currently, the initial stockholders own approximately 42.9% of MUDS’ issued and outstanding common stock, including all of the Class B shares.

Concurrently with the signing of the Purchase Agreement, Acquisition Sub, the 1.25 Lien Noteholders and the 1.5 Lien Noteholders entered into an exchange agreement (the “Exchange Agreement”), pursuant to which, as part of the consummation of the business combination, (i) the holders of New Subordinated Notes (as defined herein) in excess of the Assumed New Subordinated Notes (the “Excess Notes,” and such holders, the “Excess Noteholders”) will transfer the Excess Notes to Acquisition Sub in exchange for an amount equal to 100% of the total principal amount outstanding thereunder (plus accrued but unpaid interest and outstanding fees thereon), paid in cash to the extent of any excess of (a) the sum of (w) cash remaining in MUDS’ trust account following the satisfaction of MUDS’ stockholder redemptions, (x) the difference (not below zero) between (A) $65,000,000 and (B) the cash remaining in the trust account in excess of $󰏗0,000,000 following the satisfaction of the MUDS stockholder redemptions, (y) the net proceeds from the forward purchase and (z) the net proceeds from the Sprott Credit Agreement and Sprott Royalty Agreement (as defined herein), over (b) $220,000,000 (such excess amount, the “Cash Available for Payment” and the amount of cash therefore paid in respect of the Excess Notes, the “Excess Notes Cash Payment Amount”), and the balance, if any, to be paid in respect of the Excess Notes shall be paid in HYMC Class A common stock valued at $10.00 per share (any such balance, the “Excess Notes Share Payment Amount” and the number of shares issued in respect thereof, the “Excess Notes Share Payment”), and (ii) the 1.5 Lien Noteholders will transfer the 1.5 Lien Notes to Acquisition Sub in exchange for an amount equal to 110% of the total principal amount outstanding thereunder (plus accrued but unpaid interest and outstanding fees thereon), paid in cash to the extent that there is remaining Cash Available for Payment after any cash payments with respect to the Excess Notes are made (provided, that such cash payment amounts will be reduced such that MUDS has not less than $70,000,000 in unrestricted and available cash after giving effect to the business combination and the cash payments in respect of the Excess Notes and 1.5 Lien Notes) (such amounts to be paid in cash, the “1.5 Lien Cash Payment Amount”), and the balance, if any, to be paid in respect of the 1.5 Lien Notes shall be paid in HYMC Class A common stock valued at $10.00 per share

(any such balance, the “1.5 Lien Share Payment Amount,” and the number of shares issued in respect thereof, the “1.5 Lien Share Payment”).

Concurrently with the signing of the Purchase Agreement, MUDS entered into subscription/backstop agreements (the “Subscription/Backstop Agreements”) with certain funds affiliated with or managed by Mudrick Capital, Whitebox, Highbridge, Aristeia and Wolverine (the “Initial Subscribers”), pursuant to which MUDS will issue and sell to the Initial Subscribers $65,000,000 of MUDS Class A common stock at a purchase price of $10.00 per share, and the Initial Subscribers will receive an aggregate of 3,250,000 warrants to purchase MUDS Class A common stock at a price of $11.50 per share, in each case, in connection with and conditioned upon the consummation of the business combination. Pursuant to the terms of the Subscription/Backstop Agreements, if (a) prior to the consummation of the business combination, MUDS enters into subscription agreements or other instruments pursuant to which MUDS agrees to issue and sell to certain Third-Party Private Investors all or any portion of the shares to be issued in connection with the transactions contemplated by the Subscription/Backstop Agreements or (b) in connection with the consummation of the business combination, the cash remaining in MUDS’ trust account following the satisfaction of stockholder redemptions exceeds $10,000,000, then the aggregate number of shares to be issued to the Initial Subscribers may be correspondingly reduced such that, at the consummation of the business combination, an amount of HYMC Class A common stock equal to the difference (not less than zero) between (i) $65,000,000 and (ii) the amount of cash in excess of $10,000,000 remaining in MUDS’ trust account following the satisfaction of stockholder redemptions will be issued to the Initial Subscribers and such Third-Party Private Investors (as defined herein), in the aggregate, at a purchase price of $10.00 per share (the consummation of the transactions contemplated by the Subscription/Backstop Agreements and/or such other subscription agreements, collectively, the “private investment”).

Concurrently with the signing of the Purchase Agreement, sponsor entered into a letter agreement (the “Parent Sponsor Letter Agreement”) pursuant to which sponsor agreed to surrender to MUDS, immediately prior to the consummation of the business combination and for no consideration, a number of shares of MUDS Class B common stock, par value $0.0001 per share, equal to (i) 1,941,667 plus (ii) the product of (A) 1,941,667 and (B) the difference between (I) 1 and (II) a fraction (not greater than 1), the numerator of which is the sum of (x) the amount of proceeds from subscription agreements with Third-Party Private Investors other than the Subscription/Backstop Agreements and (y) the amount of cash remaining in MUDS’ trust account following the satisfaction of stockholder redemptions, and the denominator of which is $65,000,000 (the “Surrendered Shares”).

Concurrently with the consummation of the business combination, sponsor will purchase 2,500,000 MUDS units having substantially the same terms as the units sold in the IPO and 625,000 shares of MUDS Class A common stock, for gross proceeds of $25,000,000, in accordance with the terms of the Forward Purchase Contract.

At the closing of the business combination, HYMC, sponsor, Cantor, certain current officers and directors of MUDS, the Excess Noteholders, the 1.5 Lien Noteholders, certain stockholders of Seller that receive HYMC Class A common stock in the business combination and may be affiliates of HYMC after consummation of the business combination, the Initial Subscribers and any other Third-Party Private Investors, and Lender (such officers and directors, Cantor, the Excess Noteholders, the 1.5 Lien Noteholders, certain stockholders of Seller, Initial Subscribers, Third-Party Private Investors, if applicable, Lender and sponsor, collectively the “restricted stockholders”) will enter into an Amended and Restated Registration Rights Agreement with HYMC substantially in the form attached to the accompanying joint proxy statement/prospectus as Annex D in respect of shares of Class A common stock and, to the extent applicable, warrants, held by them, providing for, among other things, customary registration rights, including demand, piggy-back and shelf registration rights, subject to cut-back provisions. See the section entitled “The Purchase Agreement and Related Agreements — Related Agreements — Amended and Restated Registration Rights Agreement” in the accompanying joint proxy statement/prospectus for more information.

Pursuant to MUDS’ existing charter, a holder of MUDS’ public shares may request that MUDS redeem all or a portion of such stockholder’s public shares for cash if the business combination is consummated. You will be entitled to receive cash for any public shares to be redeemed if, prior to 5:00 p.m. Eastern Time

TABLE OF CONTENTS

on [•], 2020 (two business days before the MUDS special meeting), you tender your shares physically or electronically and submit a request in writing that MUDS redeem your public shares for cash to MUDS’ transfer agent.

Holders of public units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their public units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the public units into the underlying public shares and public warrants, or if a holder holds public units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so. Public stockholders may elect to redeem their public shares even if they vote “for” the Business Combination Proposal. If the business combination is not consummated, the public shares will not be redeemed for cash. If a public stockholder properly exercises its right to redeem its public shares and timely delivers its shares to the transfer agent, MUDS will redeem each public share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established in connection with the IPO (the “trust account”), calculated as of two business days prior to the consummation of the business combination, including interest not previously released to MUDS to pay its franchise and income taxes, divided by the number of then issued and outstanding public shares. For illustrative purposes, as of April 3, 2020, this would have amounted to approximately $10.40 per public share. If a public stockholder exercises its redemption rights, then it will be exchanging its redeemed public shares for cash and will no longer own such shares. See the section entitled “Special Meeting of MUDS Stockholders — Redemption Rights” in the accompanying joint proxy statement/prospectus for a detailed description of the procedures to be followed if you wish to redeem your public shares for cash.

Notwithstanding the foregoing, a holder of public shares, together with any affiliate of such public stockholder or any other person with whom such public stockholder is acting in concert or as a “group” (as defined under Section 13(d) of the Securities Exchange Act of 1934, as amended), will be restricted from redeeming its public shares with respect to more than an aggregate of 15% of the public shares without MUDS’ prior consent. Accordingly, if a public stockholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the public shares, then any such shares in excess of that 15% limit would not be redeemed for cash unless such stockholder first obtains MUDS’ prior consent.

In no event will MUDS redeem public shares in an amount that would cause its net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) to be less than $5,000,001. Holders of public warrants do not have redemption rights in connection with the business combination.

The initial stockholders have agreed to waive their redemption rights with respect to shares of Class B common stock and with respect to any public shares they may have held in connection with the consummation of the business combination and to convert such shares of Class B common stock into shares of Class A common stock in connection with the consummation of the business combination. The shares of Class B common stock will be excluded from the pro rata calculation used to determine the per-share redemption price at the time of the redemptions.

Your vote is very important. Whether or not you plan to attend the MUDS special meeting, please vote as soon as possible by following the instructions in this joint proxy statement/prospectus to make sure that your shares are represented at the MUDS special meeting. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that your shares are represented and voted at the MUDS special meeting. The transactions contemplated by the Purchase Agreement, the Exchange Agreement and the Second Lien Conversion Agreement will be consummated only if the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal are approved at the MUDS special meeting. Each of the Business Combination Proposal,

TABLE OF CONTENTS

the Charter Proposals and the NASDAQ Proposal are cross-conditioned on the approval of each other. The Director Election Proposal and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal.

If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted FOR each of the proposals presented at the MUDS special meeting. If you fail to return your proxy card or fail to instruct your bank, broker or other nominee how to vote, and do not attend the MUDS special meeting in person, the effect will be that your shares will not be counted for purposes of determining whether a quorum is present at the MUDS special meeting. If you are a stockholder of record and you attend the MUDS special meeting and wish to vote in person, you may withdraw your proxy and vote in person.

Your attention is directed to the joint proxy statement/prospectus accompanying this notice (including the annexes thereto) for a more complete description of the proposed business combination and related transactions and each of the proposals.

QUESTIONS AND ANSWERS ABOUT THE PROPOSALS FOR MUDS STOCKHOLDERS

The questions and answers below highlight only selected information from this document and only briefly address some commonly asked questions about the proposals to be presented at the MUDS special meeting, including with respect to the proposed business combination. The following questions and answers do not include all the information that is important to MUDS stockholders.

Why am I receiving this joint proxy statement/prospectus?

MUDS stockholders are being asked to consider and vote upon, among other proposals, a proposal to approve and adopt the Purchase Agreement, the Exchange Agreement and the Second Lien Conversion Agreement and approve the business combination. As a result of the business combination, MUDS will acquire the Hycroft business from Seller. Subject to the terms of the Purchase Agreement, assuming consummation of the business combination on April 30, 2020, the value of the aggregate consideration in the business combination is expected to be approximately $613,600,000, which amount is inclusive of (i) the value of the HYMC Class A common stock being issued to Seller and distributed to Seller’s stockholders in the business combination (the “purchase shares”), (ii) the value of the Excess Notes and the 1.5 Lien Notes, (iii) the debt and warrant assumption and (iv) the payoff amount. The consideration to be paid to Seller will be comprised of (x) a number of shares of HYMC Class A common stock, equal to (1) (A) $325,000,000, plus (B) the value of the Surrendered Shares valued at $10.00 per share, minus (C) the sum of the 1.5 Lien Share Payment Amount and the 1.5 Lien Cash Payment Amount, minus (D) the sum of the Excess Notes Share Payment Amount and the Excess Notes Cash Payment Amount divided by (2) $10.00, and (y) the Excess Notes and the 1.5 Lien Notes. Promptly following the issuance of the purchase shares to Seller in connection with the consummation of the business combination, Seller intends to distribute the purchase shares pro rata to its stockholders and Seller will cancel and retire the Excess Notes and 1.5 Lien Notes. Please see the section entitled “The Business Combination — Consideration to Seller Stockholders in the Business Combination” beginning on page [•] of this joint proxy statement/prospectus for further details.

The MUDS special meeting will be held on [•], 2020 at 9:00 a.m. Eastern Time at the offices of Weil, Gotshal & Manges, LLP located at 767 Fifth Avenue, New York, New York, 10153.

If we make such a determination, we will announce by press release the details on how to participate as soon as practicable, which information will also be included in updated information filed by MUDS with the SEC, which would be available through the EDGAR system at www.sec.gov.

What are the specific proposals on which I am being asked to vote at the MUDS special meeting?

MUDS stockholders are being asked to approve the following proposals:

Proposal No. 1 — The Business Combination Proposal — To consider and vote upon a proposal to

TABLE OF CONTENTS

approve and adopt the Purchase Agreement, the Exchange Agreement, the Second Lien Conversion Agreement and the business combination, which we refer to as the “Business Combination Proposal”;

Proposal No. 2 — To consider and vote upon an amendment to MUDS’ existing charter to increase the total number of authorized shares of all classes of capital stock from 111,000,000 shares to 410,00,000, which would consist of (a) 400,000,000 shares of Class A common stock and (b) 10,000,000 shares of preferred stock;

TABLE OF CONTENTS

Why is MUDS providing stockholders with the opportunity to vote on the business combination?

Under MUDS’ current certificate of incorporation, MUDS must provide all holders of public shares with the opportunity to have their public shares redeemed upon the consummation of its initial business combination either in conjunction with a tender offer or in conjunction with a stockholder vote. For business and other reasons, MUDS has elected to provide its stockholders with the opportunity to have their public shares redeemed in connection with a stockholder vote rather than a tender offer. Therefore, MUDS is seeking to obtain the approval of its stockholders of the Business Combination Proposal in order to allow its public stockholders to effectuate redemptions of their public shares in connection with the closing of the business combination. The approval of MUDS’ stockholders of the Business Combination Proposal is also a condition to the closing of the business combination under the Purchase Agreement.

When is the business combination expected to be completed?

The consummation of the business combination is expected to take place on or prior to the second business day following the satisfaction or waiver of the conditions set forth in the Purchase Agreement and described below in the subsection entitled “The Purchase Agreement and Related Agreements — Conditions to Closing of the Business Combination.” The closing of the business combination, which is expected in the first half of 2020, is subject to customary and other closing conditions, including regulatory approvals and receipt of approvals from MUDS’ stockholders and Seller’s stockholders. The Purchase Agreement may be terminated by MUDS or Seller if the consummation of the business combination has not occurred by August 12, 2020 (the “outside date”), as a result of the approval by MUDS’ stockholders at a special meeting held on February 10, 2020, to extend the deadline for completion of a business combination from February 12, 2020 to August 12, 2020 (the “Extension Meeting” and such extension, the “extension”).

For a description of the conditions to the completion of the business combination, please see the section entitled “The Purchase Agreement and Related Agreements — Conditions to Closing of the Business Combination” of this joint proxy statement/prospectus.

Following the business combination, will MUDS’ securities continue to trade on a stock exchange?

Yes. Our publicly-traded units, MUDS Class A common stock and warrants are currently listed on the NASDAQ Capital Market under the symbols “MUDSU,” “MUDS” and “MUDSW,” respectively.

TABLE OF CONTENTS

We intend to apply to continue the listing of our publicly-traded Class A common stock and warrants on NASDAQ under the proposed symbols “HYMC” and “HYMCW,” respectively, upon the consummation of the business combination. As a result, our publicly-traded units will separate into the component securities upon consummation of the business combination and, as a result, will no longer trade as a separate entity.

Q: What happens if I sell my shares of MUDS Class A common stock before the MUDS special meeting?

The record date for the MUDS special meeting is earlier than the date that the business combination is expected to be completed. If you transfer your shares of MUDS Class A common stock after the record date, but before the MUDS special meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the MUDS special meeting. However, you will not be able to seek redemption of the shares of MUDS Class A common stock because you will no longer be able to deliver them for redemption upon consummation of the business combination. If you transfer your shares of MUDS Class A common stock prior to the record date, you will have no right to vote those shares at the MUDS special meeting or redeem those shares for a pro rata portion of the proceeds held in the trust account.

If my shares are held in “street name,” will my broker, bank or nominee automatically vote my shares for me?

Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your shares with respect to non-routine matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee. MUDS believes the proposals presented to the stockholders at the MUDS special meeting will be considered non-routine and, therefore, your broker, bank, or nominee cannot vote your shares without your instruction on the proposals presented at the MUDS special meeting. As a result, your shares will not be voted on any matter unless you affirmatively instruct your broker, bank or nominee how to vote yours shares in one of the ways indicated by your broker, bank or nominee. If you do not provide instructions with your proxy, your broker, bank, or other nominee may deliver a proxy card expressly indicating that it is NOT voting your shares on any proposal; this indication that a broker, bank, or nominee is not voting your shares is referred to as a “broker non-vote.” Broker non-votes will not be counted for purposes of determining the existence of a quorum or for purposes of determining the number of votes cast at the MUDS special meeting in respect of any proposal. Your bank, broker or other nominee can vote your shares only if you provide instructions on how to vote. You should instruct your broker to vote your shares in accordance with directions you provide.

What constitutes a quorum at the MUDS special meeting?

Holders of a majority in voting power of MUDS’ common stock issued and outstanding and entitled to vote at the MUDS special meeting, present in person or represented by proxy, constitute a quorum. The initial stockholders, who currently own approximately 42.9% of MUDS’ issued and outstanding shares of common stock, will count towards this quorum. At the MUDS special meeting, we will count a properly executed proxy marked “ABSTAIN” with respect to a particular proposal as present for purposes of determining whether a quorum is present. Broker non-votes will not be counted for purposes of determining the existence of a quorum. In the absence of a quorum, the chairman of the MUDS special meeting has power to adjourn the MUDS special meeting. As of the record date for the MUDS special meeting, 6,054,644 shares of MUDS common stock would be required to achieve a quorum.

What vote is required to approve the proposals presented at the MUDS special meeting?

TABLE OF CONTENTS

quorum is established, but will have no effect on the vote with respect to such proposals. Broker non-votes will also have no effect on the vote with respect to such proposals. The initial stockholders have agreed to vote their founder shares and any public shares they may hold in favor of the business combination. Currently, the initial stockholders own approximately 42.9% of MUDS’ issued and outstanding common stock, including all of the outstanding founder shares.

The approval of the Charter Proposals requires the affirmative vote of the holders of a majority of MUDS’ outstanding shares of common stock entitled to vote thereon at the MUDS special meeting. Accordingly, if a valid quorum is otherwise established, a stockholder’s failure to vote by proxy or in person at the MUDS special meeting, as well as an abstention from voting and a broker non-vote with regard to the Charter Proposals, each will have the same effect as a vote “AGAINST” such Charter Proposals.

Directors are elected by a plurality of the votes cast by holders of MUDS’ outstanding shares of common stock represented in person or by proxy at the MUDS special meeting and entitled to vote thereon. This means that the seven director nominees who receive the most affirmative votes will be elected. Stockholders may not cumulate their votes with respect to the election of directors. Assuming a valid quorum is established, abstentions, broker non-votes and failure to vote by proxy or in person will have no effect on the election of directors.

How many votes do I have at the MUDS special meeting?

MUDS stockholders are entitled to one vote on each proposal presented at the MUDS special meeting for each share of common stock held of record as of [•], 2020, the record date for the MUDS special meeting. As of the close of business on the record date, there were 12,109,287 shares of common stock outstanding.

How will the sponsor, directors and officers vote?

In connection with the IPO, the initial stockholders agreed to vote their founder shares and any public shares purchased during or after the IPO in favor of the business combination. None of the sponsor, directors or officers has purchased any shares of common stock during or after the IPO and, as of the date of this joint proxy statement/prospectus, neither we nor sponsor, the directors or officers have entered into agreements, and are not currently in negotiations, to purchase shares prior to the consummation of the business combination. Currently, the initial stockholders own approximately 42.9% of MUDS’ issued and outstanding shares of common stock, including all of the founder shares, and will be able to vote all such shares at the MUDS special meeting.

What happens if I vote against the Business Combination Proposal?

If you vote against the Business Combination Proposal but the Business Combination Proposal still obtains the affirmative vote of a majority of the votes cast by holders of MUDS’ outstanding shares of common stock represented in person or by proxy at the MUDS special meeting and entitled to vote thereon, then the Business Combination Proposal will be approved and, assuming the approval of the NASDAQ Proposal and the Charter Proposals and the satisfaction or waiver of the other conditions to closing, the business combination will be consummated in accordance with the terms of the Purchase Agreement, the Exchange Agreement and the Second Lien Conversion Agreement.

If you vote against the Business Combination Proposal and the Business Combination Proposal does not obtain the affirmative vote of a majority of the votes cast by holders of outstanding shares of common stock represented in person or by proxy at the MUDS special meeting and entitled to vote thereon, then the Business Combination Proposal will fail and we will not consummate the business combination.

Do I have redemption rights?

If you are a public stockholder and you properly exercise your right to redeem your public shares and timely deliver your shares to the transfer agent, MUDS will redeem each public share for a per-share

TABLE OF CONTENTS

price, payable in cash, equal to the aggregate amount then on deposit in the trust account, calculated as of two business days prior to the consummation of the business combination, including interest not previously released to MUDS to pay its franchise and income taxes, divided by the number of then issued and outstanding public shares; provided, that MUDS will not redeem any public shares to the extent that such redemption would result in MUDS having net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) of less than $5,000,001. A public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13(d) of the Exchange Act), will be restricted from redeeming in this aggregate his, her or its shares or, if part of such a group, the group’s shares, in excess of 15% of the shares of common stock included as part of units sold in the IPO unless such stockholder obtains MUDS’ prior consent. Holder of MUDS’ outstanding public warrants do not have any redemption rights in connection with the business combination.

The initial stockholders have agreed to waive their redemption rights with respect to their founder shares and with respect to any public shares they may hold in connection with the consummation of the business combination. The founder shares will be excluded from the pro rata calculation used to determine the per-share redemption price. For illustrative purposes, based on the fair value of marketable securities held in the trust account of approximately $71,842,116 as of April 3, 2020, the estimated per share redemption price would have been approximately $10.40. Additionally, shares properly tendered for redemption will only be redeemed if the business combination is consummated; otherwise holders of such shares will only be entitled to a pro rata portion of the trust account (including interest but net of franchise and income taxes payable) in connection with the liquidation of the trust account, unless we complete an alternative business combination prior to August 12, 2020, as a result of the extension.

Can MUDS’ initial stockholders redeem their founder shares in connection with consummation of the business combination?

No. The initial stockholders have agreed to waive their redemption rights with respect to their founder shares and any public shares they may hold in connection with the consummation of the business combination.

Is there a limit on the number of shares that may be redeemed?

Yes. A public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13(d) of the Exchange Act), is restricted from seeking redemption rights with respect to more than an aggregate of 15% of the shares of common stock included as part of units sold in the IPO without MUDS’ prior consent. Accordingly, all shares in excess of 15% owned by a public stockholder will not be redeemed for cash without such stockholder first obtaining MUDS’ prior consent. On the other hand, a public stockholder who holds less than 15% of the public Class A common stock may redeem all of the public shares held by such public stockholder for cash.

In no event is your ability to vote all of your shares (including those shares held by you in excess of 15% of the shares of common stock included as part of units sold in the IPO) for or against the business combination restricted.

There is no specified maximum redemption threshold under MUDS’ existing charter, other than the aforementioned 15% threshold. Each redemption of Class A common stock by public stockholders will reduce the amount in the trust account. The Purchase Agreement provides that MUDS’ and Seller’s respective obligations to consummate the business combination are conditioned on (i) immediately prior to the consummation of the business combination, the amount in the trust account and the proceeds from the private investment and the Forward Purchase Contract and available under the Sprott Credit Agreement and the Sprott Royalty Agreement equaling or exceeding $210,000,000, and (ii) immediately after the consummation of the business combination and after payment in respect of all stockholder redemptions, the payoff amount and any payments due to the Excess Noteholders and the 1.5 Lien Noteholders in the exchange, if any, unrestricted and available cash equaling or exceeding $50,000,000. In addition, in no event will MUDS redeem public shares in connection with the business combination

TABLE OF CONTENTS

in an amount that would cause its net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) to be less than $5,000,001. Holders of public warrants do not have redemption rights in connection with the business combination.

Will my vote affect my ability to exercise redemption rights?

No. You may exercise your redemption rights whether you vote your shares of common stock for or against, or whether you abstain from voting on the Business Combination Proposal or any other proposal described by this joint proxy statement/prospectus. As a result, the business combination can be approved by stockholders who will redeem their shares and no longer remain stockholders, leaving stockholders who choose not to redeem their shares holding shares in a company with a potentially less-liquid trading market, fewer stockholders, potentially less cash and the potential inability to meet the listing standards of NASDAQ.

How do I exercise my redemption rights?

In order to exercise your redemption rights, you must: (i) if you hold public units, separate the underlying public shares and public warrants, and (ii) prior to 5:00 p.m Eastern Time on [•], 2020 (two business days before the MUDS special meeting), (x) tender your shares physically or electronically and (y) submit a request in writing that MUDS redeem your public shares for cash to Continental Stock Transfer & Trust Company, MUDS’ transfer agent, at the following address:

Please state in your written redemption request sent to Continental Stock Transfer & Trust Company, MUDS’ transfer agent, if you are not acting in concert or as a “group” (as defined under Section 13(d) of the Exchange Act) with any other stockholder with respect to shares of common stock. Notwithstanding the foregoing, a holder of the public shares, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13(d) of the Exchange Act) will be restricted from exercising redemption rights with respect to more than an aggregate of 15% of the shares of Class A common stock included in the units sold in the IPO without MUDS’ prior consent. Accordingly, all public shares in excess of the 15% threshold beneficially owned by a public stockholder or group will not be redeemed for cash unless such stockholder first obtains MUDS’ prior consent.

Stockholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from the transfer agent time to effect delivery. It is our understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. However, MUDS does not have any control over this process and it may take longer than two weeks. Stockholders who hold their shares in “street name” will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically.

Stockholders seeking to exercise their redemption rights, whether they are record holders or hold their shares in “street name,” are required to either tender their certificates to the transfer agent prior to the date set forth in these proxy materials or deliver their shares to the transfer agent electronically using Depository Trust Company’s (“DTC”) Deposit/Withdrawal At Custodian (“DWAC”) system, at such stockholder’s option. Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with our consent, until the vote is taken on the business combination. If you delivered your shares for redemption to our transfer agent and decide within the required timeframe not to exercise your redemption rights, you may request that our transfer agent return the shares (physically or electronically). The requirement for physical or electronic delivery prior to the MUDS special meeting ensures that a redeeming stockholder’s election to redeem is irrevocable once the business combination is approved.

TABLE OF CONTENTS

There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge a tendering broker a fee and it is in the broker’s discretion whether or not to pass this cost on to the redeeming stockholder. However, this fee would be incurred regardless of whether or not MUDS requires stockholders seeking to exercise redemption rights to tender their shares, as the need to deliver shares is a requirement to exercising redemption rights, regardless of the timing of when such delivery must be effectuated.

What are the U.S. federal income tax consequences of exercising my redemption rights or choosing not to exercise such redemption rights?

As described more fully below, a U.S. Holder of MUDS Class A common stock that exercises its redemption rights to receive cash in exchange for such shares may be treated as selling ordinary shares resulting in the recognition of capital gain or capital loss (assuming such U.S. Holder holds its MUDS Class A common stock as a capital asset). There may be certain circumstances in which the redemption may be treated as a distribution as an amount equal to the redemption proceeds, for U.S. federal income tax purposes, depending on the amount of ordinary shares or common stock, as the case may be, that a U.S. Holder owns or is deemed to own by attribution (including through the ownership of warrants).

Please see the section entitled “Material Tax Considerations — MUDS Material U.S. Federal Income Tax Considerations” of this joint proxy statement/prospectus for a discussion of material U.S. federal income tax consequences of exercising your redemption rights or choosing not to exercise such redemption rights. You are urged to consult your tax advisors regarding the tax consequences of exercising your redemption rights.

If I am a public warrant holder, can I exercise redemption rights with respect to my public warrants?

No. The holders of public warrants have no redemption rights with respect to the public warrants in connection with the business combination.

If I am a public unit holder, can I exercise redemption rights with respect to my public units?

No. Holders of outstanding units must separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares.

If you hold units registered in your own name, in order to redeem your underlying shares you must deliver the certificate for such units to Continental Stock Transfer & Trust Company, MUDS’ transfer agent, with written instructions to separate such units into public shares and public warrants. This must be completed far enough in advance to permit the mailing of the public share certificates back to you so that you may then exercise your redemption rights with respect to the public shares.

If a broker, dealer, commercial bank, trust company or other nominee holds your units, you must instruct such nominee to separate your units. Your nominee must send written instructions by facsimile to Continental Stock Transfer & Trust Company, MUDS’ transfer agent. Such written instructions must include the number of units to be split and the nominee holding such units. Your nominee must also initiate electronically, using DTC’s deposit withdrawal at custodian (DWAC) system, a withdrawal of the relevant units and a deposit of an equal number of public shares and public warrants. This must be completed far enough in advance to permit your nominee to exercise your redemption rights with respect to the public shares upon the separation of the public shares from the units. While this is typically done electronically the same business day, you should allow at least one full business day to accomplish the separation. If you fail to cause your public shares to be separated in a timely manner, you will likely not be able to exercise your redemption rights.

Do I have appraisal rights if I object to the proposed business combination?

No. Appraisal rights are not available to holders of MUDS shares in connection with the business combination.

TABLE OF CONTENTS

What happens if the business combination is not consummated?

There are certain circumstances under which the Purchase Agreement may be terminated. Please see the section entitled “The Purchase Agreement and Related Agreements — Termination” of this joint proxy statement/prospectus for information regarding the parties’ specific termination rights.

If MUDS does not consummate the business combination, we may continue to try to complete a business combination with a different target business until August 12, 2020. If MUDS fails to complete a business combination by August 12, 2020, then at such time we will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest not previously released to MUDS to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish MUDS’ public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of MUDS’ remaining stockholders and the MUDS Board, dissolve and liquidate, subject in each case to its obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including trust account assets) will be less than the initial public offering price per unit in the IPO. Please see the section entitled “Risk Factors — Risks Related to MUDS and the Business Combination” of this joint proxy statement/prospectus.

Holders of MUDS founder shares have waived any right to any liquidating distribution with respect to such shares. In addition, if MUDS fails to complete a business combination by August 12, 2020, there will be no redemption rights or liquidating distributions with respect to MUDS’ outstanding warrants, which will expire worthless.

What will be the concentration of ownership and voting power of HYMC common stock upon the closing of the business combination?

It is anticipated that, upon completion of the business combination, assuming that no shares of MUDS Class A common stock are elected to be redeemed by MUDS stockholders and subject to the assumptions set forth below, the concentration of ownership of HYMC immediately following the consummation of the business combination will be as follows:

Beneficial owners	Ownership Percentage
MUDS’ existing public stockholders		13.8%
Sponsor		12.8%
Mudrick Capital Management L.P. and affiliated fund entities		27.3%
Whitebox Advisors and affiliated fund entities		19.2%
Highbridge Capital Management LLC and affiliated fund entities		11.0%
Aristeia Capital, LLC and affiliated fund entities		7.4%
Wolverine Asset Management, LLC and affiliated fund entities		3.6%
Seller stockholders (collectively, but excluding the Initial Subscribers)		1.1%
Cantor		0.9%
Lender		1.0%
Investors in incremental private placement equity investment		2.0%

Alternatively, it is anticipated that, upon completion of the business combination, assuming all shares of MUDS Class A common stock are elected to be redeemed by MUDS stockholders and subject to the

Lender		1.0%
Investors in incremental private placement equity investment		4.0%

The ownership percentages of HYMC set forth in the foregoing tables (a) exclude (1) the shares of HYMC Class A common stock issuable upon the exercise of warrants that will remain outstanding following the business combination, including Seller warrants assumed in the business combination, and (2) any shares of HYMC Class A common stock issuable upon the conversion of mirror replacement equity awards issued to holders of outstanding Seller equity awards in connection with the business combination, and (b) assume (1) the completion of the business combination occurs on April 30, 2020, (2) the issuance of 315,788 shares (in the no redemption scenario) and 6,500,000 shares (in the maximum redemption scenario) of HYMC Class A common stock to the Initial Subscribers in the private placement, for aggregate gross proceeds of $3,157,880 or $65,000,000, respectively, (3) the issuance of 1,000,000 shares (in the no redemption scenario) and 2,000,000 shares (in the maximum redemption scenario) of HYMC Class A common stock in an incremental equity investment for aggregate gross proceeds of $10,000,000 or $20,000,000, respectively, (4) the issuance of 1% of the outstanding shares of HYMC Class A common stock to the Lender pursuant to the Sprott Credit Agreement, (5) that there is no Cash Available for Payment in connection with the consummation of the exchange and that the consideration in the exchange is comprised entirely of the Excess Notes Share Payment and the 1.5 Lien Share Payment, (6) the consummation of the transactions contemplated by the Parent Sponsor Letter Agreement, including the share surrender, on the basis of the assumptions set forth in clause (2) hereof with respect to the private investment, resulting in the surrender of 1,941,667 shares (in the no redemption scenario) or 3,584,616 shares (in the maximum redemption scenario) of MUDS Class B common stock, respectively, (7) the consummation of the underwriting commission issuance, which, on the basis of the assumptions set forth in clauses (b)(2) and (b)(3) hereof, shall result in the issuance of approximately 456,104 shares (in the no redemption scenario) or 237,067 shares (in the maximum redemption scenario) of HYMC Class A common stock, respectively, and (8) that approximately 50,001,241 shares (in the no redemption scenario) or 50,057,687 shares (in the maximum redemption scenario) of HYMC Class A common stock are outstanding immediately after consummation of the business combination.

QUESTIONS AND ANSWERS FOR SELLER STOCKHOLDERS

Why am I receiving this joint proxy statement/prospectus?

Seller stockholders are being asked to consider and vote upon a proposal to approve the Purchase Agreement and the business combination contemplated thereby. As a result of the business combination, MUDS and Acquisition Sub will acquire the Hycroft business from Seller. Seller intends to promptly distribute the shares of HYMC Class A common stock received in connection with the business combination to its stockholders on a pro rata basis, subject to the approval of the Seller Dissolution Proposal, and to wind-up its affairs after retaining sufficient assets to conduct the plan of dissolution and wind up its affairs, in accordance with the plan of dissolution. In order to complete the dissolution and liquidation of Seller pursuant to the plan of dissolution, Seller stockholders must approve the Seller Business Combination Proposal and the Seller Dissolution Proposal. Seller will hold a special meeting of its stockholders in order to obtain this approval. In connection with the business combination, Seller stockholders representing a sufficient number of shares of Seller’s outstanding common stock necessary to approve the Seller Business Combination Proposal have agreed, among other things, to vote in favor of the adoption of the Purchase Agreement and the business combination, subject to certain exceptions, and Seller stockholders representing a sufficient number of shares of Seller’s outstanding common stock necessary to approve the Seller Dissolution Proposal have also indicated their intention to vote “FOR” the Seller Dissolution Proposal. As a result, we believe that the Seller Business Combination Proposal and the Seller Dissolution Proposal will be approved by the Seller stockholders. As a result of the business combination, and assuming approval of the Seller Dissolution Proposal, pursuant to the plan of dissolution Seller will liquidate and distribute to each holder of Seller common stock, including shares of Seller common stock issued in connection with the conversion of the Second Lien Notes (as further described herein), his, her or its pro rata portion of the net assets of Seller, which are expected to consist primarily of issued and outstanding shares of HYMC Class A common stock. Seller expects that the number of shares of HYMC Class A common stock, to be received in the business combination will be equal to (1) (A) $325,000,000, plus (B) the value of the Surrendered Shares valued at $10.00 per share, minus (C) the sum of the 1.5 Lien Share Payment Amount and the 1.5 Lien Cash Payment Amount, minus (D) the sum of the Excess Notes Share Payment Amount and the Excess Notes Cash Payment Amount divided by (2) $10.00. A copy of each of the Purchase Agreement and the plan of dissolution is attached to this joint proxy statement/prospectus as Annex A and Annex E, respectively.

This joint proxy statement/prospectus and its Annexes contain important information about the Purchase Agreement and the business combination. Seller stockholders should read this joint proxy statement/prospectus and its Annexes carefully and in their entirety.

Seller stockholders are encouraged to return their proxy card as soon as possible after carefully reviewing this joint proxy statement/prospectus and its Annexes.

When and where will the Seller special meeting be held?

The Seller special meeting will be held at Seller’s offices at 8181 E. Tufts Avenue, Denver, CO 80237, on [•], 2020, at [•] a.m., unless the Seller special meeting is adjourned.

As part of our precautions regarding the novel coronavirus, COVID-19, we are planning for the possibility that the Seller special meeting may be held solely by means of remote communication. If we take this step, we will announce the decision to do so as soon as practicable, and provide details on how to participate, which will be available on our website at www.hycroftmining.com. We strongly encourage you to regularly check this website for any updates prior to the Seller special meeting.

What are the specific proposals on which I am being asked to vote at the Seller special meeting?

Seller stockholders are being asked to approve the following proposals:

Proposal No. 1 — The Seller Business Combination Proposal — To consider and vote upon a proposal to approve and adopt the Purchase Agreement and the business combination contemplated thereby, which we refer to as the “Seller Business Combination Proposal”;

TABLE OF CONTENTS

Proposal No. 2 — The Seller Dissolution Proposal — To consider and vote upon a proposal to approve and adopt the plan of dissolution attached to the joint proxy statement/prospectus as Annex E, including the dissolution and distribution of Seller’s assets contemplated thereby, subject to the approval of the Seller Business Combination Proposal and the consummation of the business combination, which we refer to as the “Seller Dissolution Proposal;” and

Proposal No. 3 — Seller Adjournment Proposal — To consider and vote upon a proposal to approve the adjournment of the Seller special meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for the approval of one or more proposals to be submitted for stockholder approval at the Seller special meeting, which we refer to as the “Seller Adjournment Proposal.”

Who is entitled to vote?

The holders of Seller common stock as of the Seller record date ([•], 2020) are entitled to vote on matters that come before the Seller special meeting. However, a stockholder may only vote his, her its shares if he, she or it is present in person or is represented by proxy at the Seller special meeting. Holders of outstanding warrants to purchase shares of Seller common stock are not entitled to vote unless such warrants are duly and validly exercised prior to the record date of the Seller special meeting.

How can I vote?

If you are a holder of record of Seller common stock on the record date, you may vote in person at the Seller special meeting or by submitting a proxy for the Seller special meeting. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card to Seller’s secretary by mail to Hycroft Mining Corporation at 8181 E. Tufts Ave., Suite 510, Denver, CO 80237, Attention: Corporate Secretary, so that it is received by Seller’s secretary prior to the vote at the Seller special meeting (which is scheduled to take place on [•], 2020).

How many votes do I have?

Each share of Seller common stock is entitled to one vote per share at the Seller special meeting. As of the close of business on the Seller record date, there were 2,897,568 shares of Seller common stock outstanding and entitled to vote.

What constitutes a quorum?

A quorum of Seller stockholders is necessary to hold a valid meeting. A quorum will be present at the Seller special meeting if a majority of the issued and outstanding shares entitled to vote is represented in person or by proxy at the special meeting. As of the Seller record date for the Seller special meeting, 1,448,785 shares of Seller common stock would be required to achieve a quorum. At the Seller special meeting, we will count a properly executed proxy marked “ABSTAIN” with respect to a particular proposal as present for purposes of determining whether a quorum is present.

What vote is required to approve the proposals presented at the Seller special meeting?

The approval of the Seller Business Combination Proposal and the Seller Dissolution Proposal require the affirmative vote of a majority of the outstanding shares of Seller common stock entitled to vote at the Seller special meeting. Accordingly, if a valid quorum is otherwise established, a stockholder’s failure to vote by proxy or in person at the Seller special meeting as well as an abstention from voting with regard to the Business Combination Proposal and the Seller Dissolution Proposal, will have the same effect as a vote “AGAINST” such proposal.

TABLE OF CONTENTS

The approval of the Seller Adjournment Proposal requires the affirmative vote for the proposal by the holders of a majority of the shares of common stock represented in person or by proxy and voting at the Seller special meeting. If a valid quorum is established, a stockholder’s failure to vote by proxy or in person at the Seller special meeting will have no effect on the outcome of any vote on the Seller Adjournment Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the vote with respect to such proposal.

What are the recommendations of the Seller Board?

The Seller Board recommends that Seller stockholders vote “FOR” the Business Combination Proposal and “FOR” the Seller Dissolution Proposal. The Seller Board has determined that the business combination is expedient, fair to, and in the best interests of, Seller and its stockholders and it has determined that the plan of dissolution is advisable and in the best interests of Seller and its stockholders. Accordingly, the Seller Board has approved the Purchase Agreement and the business combination contemplated thereby and the plan of dissolution. For a more complete description of the recommendation of the Seller Board, please see “Seller Special Meeting” beginning on page [•] of this joint proxy statement/prospectus.

The existence of financial and personal interests of one or more of Seller’s directors may result in a conflict of interest on the part of such director(s) between what he or they may believe is in the best interests of Seller and its stockholders and what he or they may believe is best for himself or themselves in determining to recommend that stockholders vote for the proposals. For a more detailed discussion, please see the section entitled “Seller Special Meeting — Recommendation to Seller’s Stockholders” beginning on page [•] of this joint proxy statement/prospectus.

How do other Seller stockholders intend to vote?

In connection with the business combination, each of Mudrick Capital, Highbridge, Whitebox, Aristeia and Wolverine and the investment funds affiliated with or managed by Mudrick Capital, Highbridge, Whitebox, Aristeia and Wolverine, representing stock holdings of more than a majority of the outstanding Seller common stock, have entered into the Seller Support Agreement pursuant to which they have agreed to support and vote all of their shares of Seller common stock in favor of the Seller Business Combination Proposal. Each of Mudrick Capital, Highbridge and Whitebox and the investment funds affiliated with or managed by Mudrick Capital, Highbridge and Whitebox have also indicated their intention to vote “FOR” the Seller Dissolution Proposal.

What happens if the business combination is not approved or consummated?

If the Seller Business Combination Proposal is not adopted by Seller’s stockholders or if the business combination is not completed for any other reason, Seller will remain an independent private company. Seller does not intend to adopt and implement the plan of dissolution to liquidate, dissolve and distribute its assets unless the business combination is completed. Seller has incurred recurring operating losses and continues to have working capital funding requirements. If the business combination is not approved and consummated on a timely basis, and/or Seller does not obtain substantial new debt or private investment on a timely basis, Seller would not likely have sufficient resources to continue operations and may be required to seek protection under the U.S. Bankruptcy Code or similar relief. In such an event, it is possible that there would not be significant assets, or any assets, available for distribution to Seller’s stockholders.

What will happen if the Seller Business Combination Proposal is approved and the Seller Dissolution Proposal is not approved?

If Seller stockholders approve the Purchase Agreement and the Seller Business Combination Proposal and the related business combination but do not approve the plan of dissolution, Seller will complete the business combination as contemplated in the Purchase Agreement and will review methods to promptly distribute the HYMC Class A common stock Seller receives to its stockholders upon consummation of the business combination. In connection with the business combination, Seller stockholders representing a sufficient number of shares of Seller’s outstanding common stock necessary to approve

TABLE OF CONTENTS

the Seller Business Combination Proposal have agreed, among other things, to vote in favor of the adoption of the Purchase Agreement and the business combination, subject to certain exceptions, and Seller stockholders representing a sufficient number of shares of Seller’s outstanding common stock necessary to approve the Seller Dissolution Proposal have also indicated their intention to vote “FOR” the Seller Dissolution Proposal. As a result, we believe that the Seller Business Combination Proposal and the Seller Dissolution Proposal will be approved by the Seller stockholders.

Do Seller stockholders have appraisal rights in connection with the proposed business combination?

No. Appraisal rights are not available to holders of Seller common stock in connection with the business combination or the plan of dissolution under applicable Delaware law.

If the Seller Business Combination Proposal and the Seller Dissolution Proposal are approved and the business combination is consummated on the terms contained in the Purchase Agreement, what does Seller estimate that the holders of Sellers common stock will receive?

Each holder of issued and outstanding shares of Seller common stock, including Seller common stockholders as a result of the conversion of the Second Lien Notes (as further described herein), are expected to receive a pro rata number of shares of HYMC Class A common stock, equal to (1) (A) $325,000,000, plus (B) the value of the Surrendered Shares valued at $10.00 per share, minus (C) the sum of the 1.5 Lien Share Payment Amount and the 1.5 Lien Cash Payment Amount, minus (D) the sum of the Excess Notes Share Payment Amount and the Excess Notes Cash Payment Amount divided by (2) $10.00.

Under the plan of dissolution, Seller will file a certificate of dissolution with the Secretary of State of the State of Delaware, Seller’s jurisdiction of incorporation, to dissolve Seller as a legal entity following the satisfaction of its outstanding liabilities. Seller currently intends to file the certificate of dissolution promptly following the consummation of the business combination in order to effect the distribution to Seller’s stockholders of the HYMC Class A common stock to be received by Seller in the business combination, including holders of Seller common stock received in connection with the conversion of the Second Lien Notes into shares of Seller common stock under the Second Lien Conversion Agreement. Holders of outstanding Seller warrants to purchase shares of Seller common stock do not have rights as stockholders of Seller and will not receive any assets upon distribution pursuant to the plan of dissolution unless such holders duly and validly exercise such Seller warrants prior to the consummation of the business combination, at which time the Seller Warrant Agreement will be assumed by HYMC and the Seller warrants, subject to an equitable adjustment, will be exercisable to purchase shares of HYMC Class A common stock. Holders of Seller warrants that wish to participate in the distribution of purchase shares pursuant to the plan of dissolution must exercise their Seller warrants at a price (as of April 1, 2020) of $5.07 per share, which is substantially in excess of the value attributed to shares of Seller common stock in the business combination, which ranges from approximately $1.12 per share to $1.23 per share depending upon the number of shares of MUDS Class A common stock redeemed and the number of shares of HYMC Class A common stock issued to Seller and Seller’s noteholders in the business combination.

What do I need to do now?

Seller urges you to read carefully and consider the information contained in this joint proxy statement/prospectus, including the annexes, and to consider how the business combination and subsequent dissolution and liquidation of Seller will affect you as a stockholder of Seller. Stockholders should then vote as soon as possible in accordance with the instructions provided in this joint proxy statement/prospectus and on the enclosed proxy card.

What happens if I sell my shares of Seller common stock before the Seller special meeting?

The Seller record date for the Seller special meeting is earlier than the date of the Seller special meeting and earlier than the date that the business combination is expected to be completed. If you transfer your shares of Seller common stock after the applicable record date, but before the Seller special meeting, unless you grant a proxy to the transferee, you will retain your right to vote at such Seller special

meeting. Shares of Seller common stock are subject to the transfer restrictions set forth in Seller’s amended and restated certificate of incorporation and the Seller stockholders agreement dated as of October 22, 2015 to which all stockholders of Seller are a party. Any attempt to transfer your shares of Seller common stock must comply with the terms and conditions set forth in the amended and restated certificate of incorporation and the Seller stockholders agreement.

May I change my vote after I have returned my signed proxy card?

Yes. Stockholders may send a later-dated, signed proxy card to Seller’s secretary by mailing it to Hycroft Mining Corporation at 8181 E. Tufts Ave., Suite 510, Denver, CO 80237, Attention: Corporate Secretary, so that it is received by Seller’s secretary prior to the vote at the Seller special meeting (which is scheduled to take place on [•], 2020) or attend the Seller special meeting in person and vote. Stockholders also may revoke their proxy by sending a notice of revocation to Seller’s secretary, which must be received by Seller’s secretary prior to the vote at the Seller special meeting. Stockholders may send a notice of revocation by mailing it to Seller’s secretary to the address above or emailing it to Seller at info@hycroftmining.com.

What happens if I fail to take any action with respect to the Seller special meeting?

If you fail to take any action with respect to the Seller special meeting and the business combination and plan of dissolution are approved by stockholders and the business combination is consummated, pursuant to the plan of dissolution you will receive a distribution of your pro-rata share of the shares of HYMC Class A common stock received by Seller in the business combination and you will become a stockholder of HYMC. If you fail to take any action with respect to the Seller special meeting and the business combination and plan of dissolution are not approved, you will remain a stockholder of Seller only.

What should I do with my stock certificates?

As a result of the consummation of the business combination, holders of Seller common stock will receive shares of HYMC Class A common stock without needing to take any action and accordingly such holders should not submit the certificates relating to their shares of Seller common stock.

What should I do if I receive more than one set of voting materials?

Seller stockholders may receive more than one set of voting materials, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction cards. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares of Seller common stock.

What are the United States federal income tax consequences of the business combination, including the underlying asset sale and distribution of HYMC Class A common stock in connection with the plan of dissolution?

Subject to the qualifications set forth in this joint proxy statement/prospectus, Seller’s sale of the Hycroft business should be treated as a taxable sale of the assets comprising the Hycroft business and any gain recognized on such sale should be subject to U.S. federal income tax at the 21-percent U.S. federal corporate income tax rate. However, Seller believes that its net operating loss carryforwards should be sufficient to fully offset the gain, if any, arising from the sale. Seller’s distribution of HYMC Class A common stock to its stockholders as a liquidating distribution in connection with Seller’s plan of dissolution should be treated as a taxable sale or exchange of such HYMC Class A common stock by Seller. However, because Seller’s tax basis in the HYMC Class A common stock should be equal to such stock’s fair market value at the time of distribution, no additional gain should be recognized by Seller upon such distribution. The receipt of HYMC Class A common stock by a Seller stockholder in connection with the liquidation and dissolution of Seller should be treated as a sale or exchange of all of such Seller stockholder’s interest in Seller with respect to which such stockholder will recognize gain or loss in an amount equal to the difference, if any, between (i) the fair market value of the

Parties to the Business Combination

MUDS

MUDS is a blank check company incorporated under the laws of the State of Delaware on August 28, 2017 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses with the intention of focusing its search for a target business on companies that have recently emerged from bankruptcy court protection.

MUDS’ publicly-traded units, Class A common stock and warrants are currently listed on the NASDAQ Capital Market (“NASDAQ”) under the symbols “MUDSU”, “MUDS” and “MUDSW”, respectively. MUDS intends to apply to continue the listing of its publicly-traded Class A common stock and warrants, to be effective upon the consummation of the business combination, on NASDAQ under the proposed symbols “HYMC” and “HYMCW”, respectively. As a result, MUDS’ publicly traded units will separate into the component securities upon consummation of the business combination and, as a result, will no longer trade as a separate entity.

The mailing address of MUDS’ principal executive office is 527 Madison Avenue, 6th Floor, New York, New York 10022. The telephone number of MUDS is (646) 747-9500.

Acquisition Sub

Acquisition Sub, a Delaware corporation, is an indirect, wholly-owned subsidiary of MUDS, formed by MUDS on January 3, 2020, to consummate the business combination. In the business combination, MUDS and Acquisition Sub will acquire the Hycroft business from Hycroft.

The mailing address of Acquisition Sub’s principal executive office is MUDS principal executive office at 527 Madison Avenue, 6th Floor, New York, New York 10022. The telephone number of MUDS is (646) 747-9500.

TABLE OF CONTENTS

Hycroft

Hycroft is a U.S.-based gold producer that has historically focused on mining, developing, and exploring properties in the state of Nevada in a safe, environmentally responsible and cost-effective manner. Gold and silver sales have historically represented 100% of Hycroft’s operating revenues and are expected to represent 100% of Hycroft’s operating revenues after restart of mining operations. Accordingly, the market prices of gold and silver significantly impact Hycroft’s financial position, operating results and cash flows.

Hycroft was incorporated as Allied Nevada Gold Corp. under the laws of the State of Delaware on September 14, 2006 and commenced operations on May 10, 2007. Hycroft changed its name from Allied Nevada Gold Corp. to Hycroft Mining Corporation on October 9, 2015 in connection with its restructuring and emergence from federal bankruptcy proceedings.

As part of its restart of mining operations, Seller obtained a new feasibility study for its heap leaching process for transition and sulfide ores issued as the Hycroft Technical Report effective July 31, 2019.

The mailing address of Hycroft’s principal executive office is 8181 E. Tufts Ave., Suite 510, Denver, CO 80237. The telephone number of Hycroft is (303) 253-3267. For more information about Hycroft, please see the sections entitled “Information About Seller and the Hycroft Business,” “Seller’s Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Management After the Business Combination” of this joint proxy statement/prospectus.

The Business Combination Proposal

On January 13, 2020, MUDS entered into the Purchase Agreement, which provides for, among other things, the acquisition by MUDS and Acquisition Sub of the Hycroft business from Seller. For more information about the transactions contemplated in the Purchase Agreement, please see the sections entitled “The Business Combination” and “The Purchase Agreement and Related Agreements.” A copy of the Purchase Agreement is attached to this joint proxy statement/prospectus as Annex A.

The Seller Dissolution Proposal and Plan of Dissolution

If the business combination is completed and the plan of dissolution is approved by Seller stockholders, upon consummation of the business combination Seller intends to file a certificate of dissolution with the Secretary of State of the State of Delaware and distribute the purchase shares pro rata to its stockholders pursuant to the plan of dissolution. The filing of the certificate of dissolution will commence a formal process under which Seller will give notice of its intention to dissolve, distribute its assets, primarily consisting of shares of HYMC Class A common stock received in connection with the business combination, allow its creditors to come forward to make claims for amounts owed to them, reserve amounts for payment to its creditors (including amounts required to cover unknown or contingent liabilities), and wind-up its affairs. Any retained cash after the distribution will be used to satisfy creditors and pay the cost of winding up. The Seller Board will have the ability to establish one or more liquidating trusts for the benefit of Seller stockholders, subject to the claims of Seller’s creditors or directly for the benefit of certain creditors, and may transfer Seller assets to such trust or trusts.

Consideration to Seller Stockholders in the Business Combination and Dissolution

Holders of Seller common stock

As a result of the business combination and the subsequent dissolution of Seller and distribution of Seller’s shares of HYMC Class A common stock received in connection with the business combination, each holder of issued and outstanding shares of Seller common stock, including shares of Seller common stock received by the Second Lien Noteholders upon the conversion of the Second Lien Notes, will receive a pro rata share of the shares of HYMC Class A common stock, issued to Seller in connection with the business combination, which shall equal (1) (A) $325,000,000, plus (B) the value of the Surrendered Shares valued at $10.00 per share, minus (C) the sum of the 1.5 Lien Share Payment Amount and the 1.5 Lien Cash Payment Amount, minus (D) the sum of the Excess Notes Share Payment Amount and the Excess Notes Cash Payment Amount, in the aggregate, divided by (2) $10.00.

TABLE OF CONTENTS

Holders of Seller Equity Awards

As a condition to the business combination and as provided in MUDS’ Incentive Plan Proposal, HYMC will adopt and approve the Incentive Plan and will issue to each holder of Seller equity awards in connection with the business combination replacement equity incentive awards in the form of an equivalent value of restricted stock units convertible into shares of HYMC Class A common stock and upon substantially identical terms and vesting conditions.

Holders of Seller Warrants

The Purchase Agreement was amended on February 26, 2020 to provide for the assumption by HYMC of Seller’s liabilities and obligations under the Seller Warrant Agreement upon consummation of the transactions contemplated under the Purchase Agreement. Subject to the terms and conditions of the Purchase Agreement, each warrant of Seller outstanding and unexercised immediately prior to the effective time will be assumed by HYMC and be exercisable to purchase HYMC Class A common stock subject to an equitable adjustment of the exercise price and number of shares into which such warrants are exercisable following consummation of the transactions contemplated by the Purchase Agreement.

Redemption Rights

Pursuant to MUDS’ existing charter, a holder of MUDS public shares may request that MUDS redeem all or a portion of such stockholder’s public shares for cash if the business combination is consummated. Holders of public units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their public units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the public units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so.

TABLE OF CONTENTS

If a public stockholder properly exercises its right to redeem its public shares and timely delivers its shares to the transfer agent, MUDS will redeem each public share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, calculated as of two business days prior to the consummation of the business combination, including interest not previously released to MUDS to pay its franchise and income taxes, divided by the number of then issued and outstanding public shares; provided, that MUDS will not redeem any Class A common stock issued in the IPO to the extent that such redemption would result in MUDS having net tangible assets (as determined in accordance with Rule 3a51‑ 1(g) (1) of the Exchange Act) of less than $5,000,001. For illustrative purposes, as of April 3, 2020, this would have amounted to approximately $10.40 per public share. Notwithstanding the foregoing, a holder of the public shares, together with any affiliate of his or her or any other person with whom he or she is acting in concert or as a “group” (as defined under Section 13(d) of the Exchange Act) will be restricted from seeking redemption rights with respect to more than 15% of the shares of Class A common stock included in the units sold in the IPO unless such stockholder first obtains MUDS’ prior consent.

If a public stockholder exercises its redemption rights, then such stockholder will be exchanging its redeemed public shares for cash and will no longer own such shares. Such a holder will be entitled to receive cash for its public shares only if it properly demands redemption and delivers its shares (either physically or electronically) to MUDS’ transfer agent in accordance with the procedures described herein. If the business combination is not consummated, the public shares will not be redeemed for cash. Please see the section entitled “Special Meeting of MUDS Stockholders — Redemption Rights” of this joint proxy statement/prospectus for the procedures to be followed if you wish to redeem your shares for cash.

Upon consummation of the business combination, the Sponsor Holders will become “interested stockholders” within the meaning of Section 203 of the DGCL, but will not be subject to the restrictions on business combinations set forth in Section 203, as the MUDS Board

TABLE OF CONTENTS

approved the business combination in which the Sponsor Holders became interested stockholders prior to such time as they became interested stockholders;

We refer to Proposals No. 2 – 8 collectively as the “Charter Proposals”. Please see the sections entitled “Proposals 2 Through 8 — The Charter Proposals” of this joint proxy statement/prospectus for more information.

Other Proposals

In addition, the stockholders of MUDS will be asked to vote on:

•

a proposal to elect, assuming the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal are all approved and adopted, seven directors to the HYMC Board until the next annual meeting of stockholders, or until their respective successors are duly elected and qualified, which we refer to as the Proposal No. 9 — the Director Election Proposal”;

•

a proposal to approve and adopt, assuming the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal are all approved and adopted, the HYMC 2020 Performance and Incentive Pay Plan (the “Incentive Plan”) and the material terms thereunder, which we refer to as Proposal No. 10 — the Incentive Plan Proposal; and

Date, Time and Place of the MUDS Special Meeting

The MUDS special meeting will be held on [•], 2020 at 9:00 a.m. Eastern Time at the offices of Weil, Gotshal & Manges, LLP located at 767 Fifth Avenue, New York, New York, 10153, or at such other date, time and place to which such meeting may be adjourned or postponed, to consider and vote upon the proposals.

Voting Power; Record Date for the MUDS Special Meeting

Only MUDS’ stockholders of record at the close of business on [•], 2020, the record date for the MUDS special meeting, will be entitled to vote at the MUDS special meeting. You are entitled to one vote for each share of MUDS common stock that you owned as of the close of business on the record date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker,

TABLE OF CONTENTS

bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the record date, there were 12,109,287 shares of common stock outstanding and entitled to vote, of which 6,909,287 are shares of Class A common stock and 5,200,000 are shares of Class B common stock held by the initial stockholders.

Accounting Treatment

The business combination will be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, for financial reporting purposes, MUDS has been treated as the “acquired” company and Seller has been treated as the “acquirer”. This determination was primarily based on current stockholders of Seller having a relative majority of the voting power of the combined entity, the operations of Seller prior to the acquisition comprising the only ongoing operations of the combined entity and senior management of Seller comprising the majority of the senior management of the combined entity. At any redemption level, including the maximum, Seller’s common stockholders prior to the consummation of the business combination (and after issuance of additional shares of Seller common stock pursuant to the conversion of the Second Lien Notes) and the holders of the Excess Notes and the 1.5 Lien Notes receiving shares of MUDS Class A common stock in exchange for their notes, will hold more than 50% at a minimum, and up to approximately 94% at a maximum, of the total shares of MUDS Class A common stock which will be issued and outstanding upon consummation of the business combination.

Accordingly, for accounting purposes, the financial statements of the combined entity will represent a continuation of the financial statements of Seller. The net assets of Seller will be stated at historical cost, with no goodwill or other intangible assets recorded. Please see the section entitled “The Business Combination — Accounting Treatment” of this joint proxy statement/prospectus for more information.

Appraisal Rights of MUDS Stockholders

Appraisal rights are not available to MUDS stockholders in connection with the business combination.

TABLE OF CONTENTS

Quorum and Required Vote for Proposals for the MUDS Special Meeting

A quorum of MUDS’ stockholders is necessary to hold a valid meeting. A quorum will be present at the MUDS special meeting if holders of a majority in voting power of MUDS common stock issued and outstanding and entitled to vote at the MUDS special meeting is present in person or represented by proxy. Abstentions will count as present for the purposes of establishing a quorum at the MUDS special meeting. Broker non-votes will not be counted for purposes of determining the existence of a quorum.

If a valid quorum is established, a stockholder’s failure to vote by proxy or in person at the MUDS special meeting will have no effect on the outcome of any vote on any of the foregoing proposals. Abstentions will be counted in connection with determination of whether a valid quorum is established, but will have no effect on the vote with respect to such proposals. Broker non-votes will also have no effect on the vote with respect to such proposals. The initial stockholders have agreed to vote their founder shares and any public shares they may hold in favor of the business combination. Currently, the initial stockholders own approximately 42.9% of MUDS’ issued and outstanding common stock, including all of the outstanding founder shares.

The transactions contemplated by the Purchase Agreement, the Exchange Agreement and the Second Lien Conversion Agreement will be consummated only if the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal are approved at the MUDS special meeting. Each of the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal are cross-conditioned on the approval of each other. The Director Election Proposal and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal, the Charter Proposals and the NASDAQ Proposal. It is important for you to note that in the event that the Business Combination Proposal, the Charter Proposals or the NASDAQ Proposal do not receive the requisite vote for approval, we will not consummate the business combination.

Recommendation to MUDS’ Stockholders

The MUDS Board believes that each of the Business Combination Proposal, the Charter Proposals, the Director Election Proposal, the Incentive Plan Proposal and the NASDAQ Proposal to be presented at the MUDS special meeting is in the best interests of MUDS and MUDS’ stockholders and recommends that its stockholders vote “FOR” each of the proposals.

million in principal amount of Seller’s First Lien Notes, an aggregate of $56.7 million in principal amount of Seller’s 1.5 Lien Notes, an aggregate of $83.8 million in principal amount of Seller’s Second Lien Notes, and an aggregate of $42.1 million in principal amount of Seller’s 1.25 Lien Notes. In addition, Mudrick Capital has the right to receive any payments made in respect of the phantom shares that were awarded to Mr. Kirsch in his capacity as a non-employee director of the Seller since his appointment to the Seller Board in October 2015, which will result in the payment of approximately $0.5 million in cash to Mudrick Capital in connection with the consummation of the business combination. It is anticipated that Mr. Kirsch will remain on the board of directors of HYMC following the closing of the business combination. Mr. Kirsch did not participate as a director in meetings or votes of the Seller Board related to Seller’s consideration of the business combination and alternative transactions unless specifically requested to do so after acknowledgement and disclosure of his potential conflicts of interest. The MUDS Board was aware of and considered these interests, among other matters, in evaluating and negotiating the business combination and transaction agreements and in recommending to MUDS’ stockholders that they vote in favor of the proposals presented at the MUDS special meeting, including the Business Combination Proposal. Stockholders should take these interests into account in deciding whether to approve the proposals presented at the MUDS special meeting, including the Business Combination Proposal. Please see the sections “The Business Combination — Interests of Certain Persons in the Business Combination” and “Special Meeting of MUDS Stockholders — Recommendation to MUDS’ Stockholders” beginning on pages [•] and [•], respectively of this joint proxy statement/prospectus for more information.

Risk Factors

In evaluating the business combination and the proposals to be considered and voted on at the general meeting, you should carefully review and consider the risk factors set forth under the section entitled “Risk Factors” beginning on page [•] of this joint proxy statement/prospectus.

Special Meeting of Seller Stockholders

Date, Time and Place of Special Meeting of Seller’s Stockholders

The Seller special meeting will be held at [•] a.m. Mountain Time on [•], 2020 at the offices of Seller, 8181 E. Tufts Avenue, Denver, CO 80237, or such other date, time and place to which such meeting may be adjourned or postponed, to consider and vote upon the proposals.

Voting Power; Record Date of Special Meeting of Seller’s Stockholders

Seller’s stockholders will be entitled to vote on the matters presented at the Seller special meeting, which are fully set forth in this joint proxy statement/prospectus. Each share of Seller common stock will be entitled to vote or direct votes to be cast at the Seller special meeting if you owned Seller common stock at the close of business on the Seller record date. You are entitled to one vote for each share of Seller common stock that you held of record as of the close of business on the Seller record date. On the Seller record date, there were 2,897,568 shares of Seller common stock outstanding. Holders of Seller warrants are not considered to be stockholders and will not be entitled to vote on the matters presented at the Seller special meeting unless the Seller warrants are exercised in accordance with their terms prior to the Seller record date.

Quorum and Required Vote for Proposals for the Seller Special Meeting

A quorum of Seller stockholders is necessary to hold a valid meeting. The presence, in person or by proxy, of a majority of the issued and outstanding shares of Seller common stock entitled to vote constitutes a quorum at the Seller special meeting. Abstentions, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Seller special meeting. As of the Seller record date, [•] shares of Seller common stock would be required to achieve a quorum. The proposals presented at the Seller special meeting require the following votes:

•

Seller Business Combination Proposal: The Seller Business Combination Proposal requires the approval of a majority of the outstanding shares of Seller common stock entitled to vote under the DGCL.

•

Seller Dissolution Proposal: The Seller Dissolution Proposal requires the approval of a majority of the outstanding shares of Seller common stock entitled to vote under the DGCL.

•

Seller Adjournment Proposal: The affirmative vote of the holders of a majority of the shares of Seller common stock present in person or represented by proxy and voting at the Seller special meeting is required to adjourn the Seller special meeting.

Appraisal Rights of Seller Stockholders

Appraisal rights are not available to Seller stockholders in connection with the business combination under Delaware law.

Proxy Solicitation for Seller

Proxies may be solicited by mail, telephone or in person. If a stockholder grants a proxy, it may still vote its shares in person if it revokes its proxy before the Seller special meeting. A stockholder also may change its vote by submitting a later-dated proxy as described in the section entitled “Revoking Your Proxy” on page [•] of this joint proxy statement/prospectus.

Interests of Seller’s Directors and Officers in the Business Combination

When you consider the recommendation of Seller’s Board in favor of approval of the Seller Business Combination Proposal, you should keep in mind that Seller’s directors and officers have interests in such proposal that are different from, or in addition to, those of Seller’s stockholders generally. These interests include, among other things, the interests listed below:

•

The fact that certain of Seller’s directors and officers will continue to be directors and officers of HYMC after the consummation of the business combination. As such, in the future they will receive

TABLE OF CONTENTS

any cash fees, stock options, stock awards or other remuneration that the HYMC Board determines to pay to its directors and officers.

•

Upon completion of the business combination and the issuance of HYMC Class A common stock in the business combination assuming that the Seller stockholders receive 16,550,374 shares of HYMC Class A common stock, the directors and officers of Seller will collectively beneficially own approximately [•] of the outstanding stock of HYMC.

The existence of financial and personal interests of one or more Seller directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is best for Seller. Please see the sections entitled “Risk Factors” and “Seller Special Meeting — Recommendation to Seller Stockholders” of this joint proxy statement/prospectus for a further discussion of this and other risks.

Recommendation to Stockholders of Seller

Seller’s Board believes that the Seller Business Combination Proposal, the Seller Dissolution Proposal and the Seller Adjournment Proposal are in the best interest of Seller’s stockholders and recommends that its stockholders vote “FOR” the Seller Business Combination Proposal, “FOR” the Seller Dissolution Proposal and “FOR” the Seller Adjournment Proposal. Under the terms of the Seller Support Agreement, subject to a change in recommendation by the Seller Board, holders of approximately 58% of the outstanding common stock of Seller have agreed to vote “FOR” the Seller Business Combination Proposal and have indicated their intention to vote “FOR” the Seller Dissolution Proposal.

TABLE OF CONTENTS

RISK FACTORS

You should carefully review and consider the following risk factors and the other information contained in this joint proxy statement/prospectus, including the financial statements and notes to the financial statements included herein, in evaluating the business combination and the proposals to be voted on at the MUDS special meeting. The following risk factors apply to the Hycroft business, the operations of the Hycroft business by the Seller and will also apply to the business and operations of HYMC following the completion of the business combination. The occurrence of one or more of the events or circumstances described in these risk factors, alone or in combination with other events or circumstances, may adversely affect the ability to complete or realize the anticipated benefits of the business combination, and may have a material adverse effect on the business, cash flows, financial condition and results of operations of HYMC. You should carefully consider the following risk factors in addition to the other information included in this joint proxy statement/prospectus, including matters addressed in the section entitled “Cautionary Note Regarding Forward-Looking Statements.” HYMC may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial, which may also impair HYMC’s business or financial condition. The following discussion should be read in conjunction with the financial statements and notes to the financial statements included herein.

Risks Related to Seller’s Industry

Unless the context otherwise requires, for purposes of this section, the terms “we,” “us,” “the Company,” “Hycroft” or “our company”refer to Seller and its subsidiaries as they currently exist under the law of the state of each such entity’s formation prior to consummation of the business combination, and to HYMC from and after the consummation of the business combination.

The market prices of gold and silver are volatile. A decline in gold and silver prices could result in decreased revenues, decreased net income, increased losses and decreased cash inflows which may negatively affect our business.

Gold and silver are commodities. Their prices fluctuate and are affected by many factors beyond our control, including interest rates, expectations regarding inflation, speculation, currency values, central bank activities, governmental decisions regarding the disposal of precious metals stockpiles, global and regional demand and production, political and economic conditions and other factors. The prices of gold and silver, as quoted by The London Bullion Market Association on April 2, 2020, December 31, 2019 and December 31, 2018, were $1,617, $1,515 and $1,279 per ounce for gold, respectively, and $14.17, $18.04 and $15.46 per ounce for silver, respectively. The prices of gold and silver may decline in the future. A substantial or extended decline in gold or silver prices would adversely impact our financial position, revenues, net income and cash flows, particularly in light of our current strategy of not engaging in hedging transactions with respect to gold or silver. In addition, sustained lower gold or silver prices may:

•

reduce revenue potential due to cessation of the mining of deposits, or portions of deposits, that have become uneconomic at the then-prevailing gold or silver price;

•

reduce or eliminate the profit, if any, that we currently expect from mining operations;

•

halt, delay, modify, or cancel plans for the mining of oxide and sulfide ores or the development of new and existing projects;

•

make it more difficult for us to satisfy and/or service our debt obligations;

•

reduce existing reserves by removing ores from reserves that can no longer be economically processed at prevailing prices; and

•

cause us to recognize an impairment to the carrying values of mineral properties and long-lived assets.

Reserve and other mineralized material calculations are estimates only, and are subject to uncertainty due to factors including metal prices, inherent variability of the ore and recoverability of metal in the mining process.

The calculation of mineral reserves, mineral resources and grades are estimates and depend upon geological interpretation and statistical inferences or assumptions drawn from drilling and sampling

TABLE OF CONTENTS

analysis, which may prove to be unpredictable. There is a degree of uncertainty attributable to the calculation of mineral reserves and mineral resources, and corresponding grades. Until mineral reserves and mineral resources are actually mined and processed, the quantity of ore and grades must be considered as an estimate only. In addition, the quantity of mineral reserves and mineral resources may vary depending on metal prices, which largely determine whether mineral reserves and other mineralized materials are classified as ore (economic to mine) or waste (uneconomic to mine). A decline in metal prices may result in previously reported mineral reserves (ore) becoming uneconomic to mine (waste). Current reserve estimates were calculated using a $1,200 per ounce gold price and $16.50 per ounce silver price. A material decline in the current price of gold or silver could require a reduction in our reserve estimates. Any material change in the quantity of mineral reserves, mineral resources, mineralization, grade or stripping ratio may affect the economic viability of our properties. In addition, we can provide no assurance that gold and silver recoveries experienced in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.

Our activities may be adversely affected by the COVID-19 pandemic, whether those effects are local, nationwide or global. Matters outside our control may prevent us from executing on our mining operations, limit travel of Company representatives, adversely affect the health and welfare of Company personnel or prevent important vendors and contractors from performing normal and contracted activities, including mining operations.

The current COVID-19 pandemic is significantly impacting the national and global economy and commodity and financial markets. The full extent and impact of the COVID-19 pandemic is unknown and to date has included extreme volatility in financial markets, a slowdown in economic activity, extreme volatility in commodity prices (including precious metals) and has raised the prospect of a global recession. The response to COVID-19 has led to significant restrictions on travel, temporary business closures, quarantines, global stock market volatility and a general reduction in consumer activity, globally. Matters outside our control have affected our business and operations and may continue to: prevent us from executing on our mining operations; limit travel of Hycroft representatives, including between our corporate headquarters in Colorado and the Hycroft Mine in Nevada; adversely affect the health and welfare of Hycroft personnel; or prevent important vendors and contractors from performing normal and contracted activities, including mining operations. If significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, facility closures or other restrictions in connection with the COVID-19 pandemic, our operations will likely be adversely impacted. It is possible that the continued spread of COVID-19 could also further cause disruption in our supply chains, adversely affect our business partners, delay our mining operations or cause other unpredictable events.

We, our people, investors, contractors or other stakeholders, have been and may continue to be limited or prevented from travel or normal attendance to activities in conducting the Hycroft business, including mining operations, and conducting presentations, meetings or other activities in connection with this business combination and related transactions. The spread of COVID-19 throughout Colorado and Nevada may result in our employees being forced to work from home or missing work if they or a member of their family contract COVID-19, which could harm our operations and negatively impact our financial condition. We have and may continue to also be limited or prevented from receiving goods or services from contractors. Decisions beyond our control, such as canceled events, restricted travel, barriers to entry or other factors may affect our ability to accomplish drilling programs, mining operations, equity raising activities, and other needs that would normally be accomplished without such limitations. The extent to which the COVID-19 outbreak will impact our operations, our business and the economy is highly uncertain. We cannot predict the impact of the COVID-19 pandemic, but it may materially and adversely affect our business, financial condition and results of operations.

We face intense competition in the mining industry.

The mining industry is intensely competitive. As a result of this competition, some of which is with large established mining companies with substantial mining capabilities and with greater financial and technical resources than ours, we compete with other mining companies in the recruitment and retention of qualified managerial and technical employees and in acquiring attractive mining claims. If we are unable to successfully attract and retain qualified employees, our development programs and/or our operations may be slowed down or suspended, which may adversely impact HYMC’s development, financial condition and results of operations.

TABLE OF CONTENTS

Mining development and processing operations pose inherent risks and costs that may negatively impact our business.

Mining development and processing operations involve many hazards and uncertainties, including, among others:

•

metallurgical or other processing problems;

•

ground or slope failures;

•

industrial accidents;

•

unusual and unexpected rock formations or water conditions;

•

environmental contamination or leakage;

•

flooding and periodic interruptions due to inclement or hazardous weather conditions or other acts of nature;

•

fires;

•

seismic activity;

•

organized labor disputes or work slow-downs;

•

mechanical equipment failure and facility performance problems; and

•

the availability of critical materials, equipment and skilled labor.

These occurrences could result in damage to, or destruction of, our properties or production facilities, personal injury or death, environmental damage, delays in mining or processing, increased production costs, asset write downs, monetary losses and legal liability, any of which could have an adverse effect on our results of operations and financial condition and adversely affect HYMC’s projected development and production estimates.

Our insurance may not cover all of the risks associated with our business.

The mining business is subject to risks and hazards, including, but not limited to, construction risks, environmental hazards, industrial accidents, the encountering of unusual or unexpected geological formations, slide-ins, flooding, earthquakes and periodic interruptions due to inclement or hazardous weather conditions. These occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damage, reduced production and delays in mining, asset write-downs, monetary losses and possible legal liability. Insurance fully covering many of these risks is not generally available to us and if it is, we may elect not to obtain it because of the high premium costs or commercial impracticality. We do not currently carry business interruption insurance and have no plans as HYMC to obtain such insurance in the future. Any liabilities incurred for these risks and hazards could be significant and could adversely affect HYMC’s results of operation, cash flows and financial condition.

Environmental regulations could require us to make significant expenditures or expose us to potential liability.

To the extent we become subject to environmental liabilities, the payment of such liabilities or the costs that we may incur, including costs to remedy environmental pollution, would reduce funds otherwise available to us and could have a material adverse effect on our financial condition, results of operations, and liquidity. If we are unable to fully remedy an environmental violation or release of hazardous substances, we might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy or corrective action. The environmental standards that may ultimately be imposed at a mine site can vary and may impact the cost of remediation. Actual remedial costs may exceed the financial accruals that have been made for such remediation. The potential exposure may be significant and could have a material adverse effect on HYMC’s financial condition and results of operations.

Moreover, governmental authorities and private parties may bring lawsuits based upon damage to property or natural resources and injury to persons resulting from the environmental, health and safety impacts of our past and current operations, which could lead to the imposition of substantial fines,

TABLE OF CONTENTS

remediation costs, penalties, injunctive relief and other civil and criminal sanctions. Substantial costs and liabilities, including those required to restore the environment after the closure of mines, are inherent in our operations. We cannot provide any assurance that any such law, regulation, enforcement or private claim will not have a negative effect on HYMC’s business, financial condition or results of operations.

Our operations are subject to extensive environmental regulations, which could result in the incurrence of operational delays, penalties and costs.

All phases of our operations are subject to extensive federal and state environmental regulation, including those enacted under the following laws:

•

Comprehensive Environmental Response, Compensation, and Liability Act;

•

The Resource Conservation and Recovery Act;

•

The Clean Air Act;

•

The National Environmental Policy Act;

•

The Clean Water Act; and

•

The Safe Drinking Water Act.

Additional regulatory authorities also have jurisdiction over some of our operations and mining projects including the Environmental Protection Agency, the Nevada Division of Environmental Protection, the U.S. Fish and Wildlife Service, the U.S. Bureau of Land Management, which we refer to as the “BLM,” and the Nevada Department of Wildlife.

These environmental regulations require us to obtain various operating permits, approvals and licenses and also impose standards and controls relating to development and production activities. For instance, we are required to hold a Nevada Reclamation Permit with respect to the Hycroft Mine. This permit mandates concurrent and post-mining reclamation of mines and requires the posting of reclamation bonds sufficient to guarantee the cost of mine reclamation. Changes to the amount required to be posted for reclamation bonds for our operations at the Hycroft Mine could materially affect HYMC’s financial position, results of operations, cash flows and liquidity following consummation of the business combination. Also, the U.S. Fish and Wildlife Service may designate critical habitat and suitable habitat areas it believes are necessary for survival of a threatened or endangered species. A critical habitat or suitable habitat designation could result in further material restrictions to land use and may materially delay or prohibit land access for our development. For example, we had to obtain certain permits associated with mining in the area of an eagle habitat. Failure to obtain such required permits or failure to comply with federal and state regulations could also result in delays in beginning or expanding operations, incurring additional costs for investigation or cleanup of hazardous substances, payment of penalties for non-compliance or discharge of pollutants, and post-mining closure, reclamation and bonding, all of which could have an adverse impact on HYMC’s financial performance, results of operations and liquidity.

Compliance with current and future government regulations may cause us to incur significant costs.

Our operations are subject to extensive federal and state legislation governing matters such as mine safety, occupational health, labor standards, prospecting, exploration, production, exports, toxic and hazardous substances, explosives, management of natural resources, land use, water use, air emissions, waste disposal, environmental review and taxes. Compliance with this and other legislation could require us to make significant financial outlays. The enactment of new legislation or more stringent enforcement of current legislation may increase costs, which could have a negative effect on our financial position, results of operations, and liquidity. We cannot provide any assurances that we will be able to adapt to these regulatory developments on a timely or cost-effective basis. Violations of these laws, regulations and other regulatory requirements could lead to substantial fines, penalties or other sanctions, including possible shut-down of the Hycroft Mine or future operations, as applicable.

TABLE OF CONTENTS

Changes in environmental regulations could adversely affect our cost of operations or result in operational delays.

The regulatory environment in which we operate is evolving in a manner that will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened degree of responsibility for companies and their officers, directors and employees. New environmental laws and regulations or changes in existing environmental laws and regulations could have a negative effect on exploration activities, operations, production levels and methods of production.

We cannot provide any assurance that future changes in environmental laws and regulations will not adversely affect our current operations or future projects. Any changes to these laws and regulations could have an adverse impact on our financial performance and results of operations by, for example, requiring changes to operating constraints, technical criteria, fees or surety requirements.

Our operations are subject to numerous governmental permits that are difficult to obtain and we may not be able to obtain or renew all of the permits we require, or such permits may not be timely obtained or renewed.

In the ordinary course of business we are required to obtain and renew governmental permits for our operations, including in connection with our plans for heap leaching our transition and sulfide ores at the Hycroft Mine. We will also need additional governmental permits to accomplish our long-term plans to mine sulfide ores, including without limitation, permits to allow construction of additional leach pad space. Obtaining or renewing the necessary governmental permits is a complex and time-consuming process involving costly undertakings by us. The duration and success of our efforts to obtain and renew permits are contingent upon many variables not within our control, including the interpretation of applicable requirements implemented by the permitting authority and intervention by third parties in any required environmental review. We may not be able to obtain or renew permits that are necessary to our operations on a timely basis or at all, and the cost to obtain or renew permits may exceed our estimates. Failure to comply with the terms of our permits may result in injunctions, fines, suspension or revocation of permits and other penalties. We can provide no assurance that we have been, or will at all times, be in full compliance with all of the terms of our permits or that we have all required permits. The costs and delays associated with compliance with these permits and with the permitting process could alter the mine plan, delay or stop us from proceeding with the operation or development of the Hycroft Mine or increase the costs of development or production, any or all of which may materially adversely affect Hycroft’s business, results of operations, financial condition and liquidity.

There are uncertainties as to title matters in the mining industry. Any defects in such title could cause us to lose our rights in mineral properties and jeopardize our business operations.

Our mineral properties consist of private mineral rights, leases covering private lands, leases of patented mining claims and unpatented mining claims. Areas of the Hycroft Mine are unpatented mining claims located on lands administered by the BLM, Nevada State office to which we have only possessory title. Because title to unpatented mining claims is subject to inherent uncertainties, it is difficult to determine conclusively ownership of such claims. These uncertainties relate to such things as sufficiency of mineral discovery, proper location and posting and marking of boundaries, and possible conflicts with other claims not determinable from descriptions of record. We believe a substantial portion of all mineral exploration, development and mining in the United States now occurs on unpatented mining claims, and this uncertainty is inherent in the mining industry.

The present status of our unpatented mining claims located on public lands allows us the right to mine and remove valuable minerals, such as precious and base metals, from the claims conditioned upon applicable environmental reviews and permitting programs. We also are generally allowed to use the surface of the land solely for purposes related to mining and processing the mineral-bearing ores. However, legal ownership of the land remains with the United States. We remain at risk that the mining claims may be forfeited either to the United States or to rival private claimants due to failure to comply with statutory requirements. Prior to 1994, a mining claim locator who was able to prove the discovery of valuable, locatable minerals on a mining claim, and to meet all other applicable federal and state requirements and procedures pertaining to the location and maintenance of federal unpatented mining claims, had the right to prosecute a patent

TABLE OF CONTENTS

application to secure fee title to the mining claim from the Federal government. The right to pursue a patent, however, has been subject to a moratorium since October 1994, through federal legislation restricting the BLM from accepting any new mineral patent applications. If we do not obtain fee title to our unpatented mining claims, we can provide no assurance that we will be able to obtain compensation in connection with the forfeiture of such claims.

There may be challenges to title to the mineral properties in which we hold a material interest. If there are title defects with respect to any properties, we might be required to compensate other persons or perhaps reduce our interest in the affected property. Also, in any such case, the investigation and resolution of title issues would divert our management’s time from ongoing production and development programs.

Legislation has been proposed periodically that could, if enacted, significantly affect the cost of our operations on our unpatented mining claims or the amount of Net Proceeds of Mineral Tax we pay to the State of Nevada.

Members of the U.S. Congress have periodically introduced bills which would supplant or alter the provisions of the Mining Law of 1872. Such bills have proposed, among other things, to either eliminate or greatly limit the right to a mineral patent and to impose a federal royalty on production from unpatented mining claims. Such proposed legislation could change the cost of holding unpatented mining claims and could significantly impact our ability to develop mineralized material on unpatented mining claims. A majority of our mining claims are unpatented claims. Although we cannot predict what legislated royalties might be, the enactment of these proposed bills could adversely affect the potential for development of our unpatented mining claims and the economics of our existing operating mines on federal unpatented mining claims. Passage of such legislation could adversely affect HYMC’s financial performance and results of operations.

We pay Net Proceeds of Mineral Tax, which we refer to as “NPT,” to the State of Nevada on up to 5% of net proceeds generated from our Hycroft Mine. Net proceeds are calculated as the excess of gross yield over direct costs. Gross yield is determined as the value received when minerals are sold, exchanged for anything of value or removed from the state. Direct costs generally include the costs to develop, extract, produce, transport and refine minerals. From time to time Nevada legislators introduce bills which aim to increase the amount of NPT mining companies operating in the state pay. If legislation is passed that increases the NPT we pay to the state of Nevada, HYMC’s business, results of operations, and cash flows could be negatively impacted.

Regulations and pending legislation governing issues involving climate change could result in increased operating costs, which could have a material adverse effect on our business.

A number of governments or governmental bodies have introduced or are contemplating regulatory changes in response to various climate change interest groups and the potential impact of climate change. Legislation and increased regulation regarding climate change could impose significant costs on us and our suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. Any adopted future climate change regulations could also negatively impact our ability to compete with companies situated in areas not subject to such regulations. Given the emotion, political significance and uncertainty around the impact of climate change and how it should be dealt with, we cannot predict how legislation and regulation will affect our financial condition, operating performance and ability to compete. Furthermore, even without such regulation, increased awareness and any adverse publicity in the global marketplace about potential impacts on climate change by us or other companies in our industry could harm HYMC’s reputation.

Climate change could have an adverse impact on our cost of operations.

The potential physical impacts of climate change on our operations are highly uncertain and would be particular to the area in which we operate. These climate changes may include changes in rainfall and storm patterns and intensities, water shortages and changing temperatures. These changes in climate could adversely affect our mining operations, including by affecting the moisture levels and pH of ore on our leach pads, increase the cost of production at the Hycroft Mine and adversely affect the financial performance of HYMC’s operations.

Risks Related to the Hycroft Business

Unless the context otherwise requires, for purposes of this section, the terms “we,” “us,” “the Company,” “Hycroft” or “our company” refer to Seller and its subsidiaries as they currently exist under the law of the state of each such entity’s formation prior to consummation of the business combination, and to HYMC from and after the consummation of the business combination.

The estimation of the ultimate recovery of gold and silver from the Hycroft Mine, although based on standard industry sampling and estimating methods, is subjective. Our results of operations, liquidity, and financial position may be negatively impacted if actual recoveries are lower than initial estimations.

Our Hycroft Mine historically utilized a heap leach process to extract gold and silver from ore. Our new plans outlined in the Hycroft Technical Report are also based on a heap leach process. The heap leach process extracts gold and silver by placing ore on an impermeable pad and applying a dilute cyanide solution that dissolves a portion of the contained gold and silver, which are then recovered in metallurgical processes. We use several integrated steps in the process of extracting gold and silver to estimate the metal content of ore placed on the leach pad. Although we refine our estimates as appropriate at each step in the process, the final amounts are not determined until a third-party smelter refines the doré and/or metal-laden carbon and determines the final ounces of gold and silver available for sale. We then review this end result and reconcile it to the estimates we developed and used throughout the production process. Based on this review, we adjust our estimation procedures when appropriate. Due to the complexity of the estimation process and the number of steps involved, among other things, actual recoveries can vary from estimates, and the amount of the variation could be significant and could have a material adverse impact on our financial condition, results of operations and liquidity.

There is only limited experience of recovering gold and silver from sulfide ores using a heap leaching process and we may not be able to economically recover gold and silver.

Under our current mine plan, we have begun to mine and extract gold and silver from transition and sulfide ores using a two-step pre-oxidation process on transition and sulfide ores using soda ash to manage pH and alkalinity during the oxidation process in accordance with the methods set forth in the Hycroft Technical Report. However, the economic parameters described in the Hycroft Technical Report include a number of assumptions and estimates that could prove to be incorrect. Additionally, this two-step process to oxidize transition and sulfide ores before heap leaching to extract gold and silver is a new and relatively untested process, is used only on a limited basis worldwide and has not been widely accepted as a viable process. We cannot provide any assurance that the development and advancement of the Hycroft Mine transition and sulfide ores leaching operations will result in economically viable mining operations, yield new mineral reserves or other mineralized material, enable us to convert other mineralized material (included within mineral resources identified by the feasibility study), or be implemented on an economic and profitable basis.

Cost estimates of operating our Hycroft Mine are uncertain, which may adversely affect our expected production and profitability.

The expenditures to implement our new two-stage pre-oxidation and leach process, and access our transition and sulfide ores, are considerable and changes in costs, construction schedules, commodity prices and other factors can adversely affect project economics and expected production and profitability. There are a number of factors that can affect costs and construction schedules and result in our assumptions and estimates about the anticipated benefits of a project being incorrect, including, among others:

•

changes in input commodity prices and labor costs;

•

recovery rates of gold and silver from the ore;

•

availability and terms of financing;

•

availability of labor, energy, transportation, equipment, and infrastructure;

•

changes in anticipated tonnage, grade and metallurgical characteristics of the ore to be mined and processed;

TABLE OF CONTENTS

•

difficulty of estimating construction costs over a period of years;

•

delays in completing any environmental review or in obtaining environmental or other governmental permits;

•

weather and severe climate impacts; and

•

potential delays related to social and community issues.

We have previously recovered gold and silver from oxide and transition ores at the Hycroft Mine through our heap leach operations. In connection with our restarted mining operations, in addition to mining oxide ore, we are also mining gold and silver from transition and sulfide ores using a modified heap leach process, in which soda ash is being used to manage pH and alkalinity in a two-stage oxidation and leach process, in accordance with the Hycroft Technical Report. However, it is important to note that the economic parameters described in a feasibility study, such as the Hycroft Technical Report, include a number of assumptions and estimates that could prove to be incorrect. We use feasibility studies to make a reasoned determination of whether to proceed with a project and to support the required financing for a project but you should not assume that the economic analysis contained in a feasibility study is a guarantee of future performance or that the estimated net present value or internal rates of return will be achieved. Actual results may differ materially. In particular, the processing of sulfide ore and additional transition ore at the Hycroft Mine is uncertain and, therefore, the costs and timing of the commencement of the production of sulfide ore and additional transition ore operations at the Hycroft Mine could vary greatly from our estimates.

We may not achieve our production and/or sales estimates and our costs may be higher than our estimates, thereby reducing our cash flows and negatively impacting our results of operations and liquidity.

We prepare estimates of future production, sales, and costs for our operations. We develop our estimates based on, among other things, mining experience, mineral reserve and resource estimates, assumptions regarding ground conditions and physical characteristics of ores (such as hardness and presence or absence of certain metallurgical characteristics), costs to construct new leach pads and estimated rates and costs of mining and processing. All of our estimates are subject to numerous uncertainties, many of which are beyond our control. Our actual production and/or sales may be lower than our estimates and our actual costs may be higher than our estimates, which could negatively impact our cash flows and results of operations. While we believe that our estimates are reasonable at the time they are made, actual results will vary and such variations may be material. These estimates are speculative in nature, and it may be the case that one or more of the assumptions underlying such projections and estimates may not materialize. You are cautioned not to place undue reliance on the projections and estimates set forth in this joint proxy statement/prospectus, any document incorporated by reference or any document attached hereto.

We currently depend on a single mine and there is no assurance that after restarting operations we will not incur any interruptions or stoppages in our mining activities which would have a material adverse effect on our results of operations and financial condition.

The Hycroft Mine is our only mining property. We can provide no assurance that we will be successful in profitably operating the Hycroft Mine using the sulfide leaching process. Further, any interruption in our ability to operate the Hycroft Mine, such as, but not limited to, a natural disaster, pandemic (such as COVID󰓆19), loss of material permits, processing interruptions or difficulties or labor strike would have a materially adverse effect on our ability to produce gold and silver and to generate revenue.

Our reliance on third party contractors and consultants to conduct our operations and construction projects exposes us to risks.

In connection with the operation of the Hycroft Mine, we will contract and engage third party contractors and consultants to assist with aspects of our operations and related construction projects, including construction of the new leach pad, repair of the crushing facility, and mining of our ore and waste. As a result, our operations and construction projects are subject to a number of risks, some of which are outside our control, including:

TABLE OF CONTENTS

•

negotiating agreements with contractors and consultants on acceptable terms;

•

the inability to replace a contractor or consultant and their operating equipment in the event that either party terminates the agreement;

•

reduced control over those aspects of operations which are the responsibility of the contractor or consultant;

•

failure of a contractor or consultant to perform under their agreement or disputes relative to their performance;

•

interruption of operations or increased costs in the event that a contractor or consultant ceases their business due to insolvency or other unforeseen events;

•

failure of a contractor or consultant to comply with applicable legal and regulatory requirements, to the extent they are responsible for such compliance; and

•

problems of a contractor or consultant with managing their workforce, labor unrest or other employment issues.

In addition, we may incur liability to third parties as a result of the actions of our contractors or consultants. The occurrence of one or more of these risks could decrease our gold and silver production, increase our costs, interrupt or delay our mining operations or our ability to access our ores, and adversely affect our liquidity, results of operations and financial position.

Our lack of exploration activities will lead to our inability to replace depleted reserves.

To maintain production levels over time we must replace depleted reserves by exploiting known ore bodies and locating new deposits. Pursuant to our emergence from bankruptcy, all of our exploration properties other than those associated with Hycroft Mine were sold in the chapter 11 proceedings. We have no current plans to continue further exploration other than related to the mining and processing of gold and silver contained in ore within the Hycroft Mine, and there can be no assurance that such projects will be successful. Our mineral base will decline if reserves are mined without adequate replacement, and we may not be able to sustain production beyond the currently contemplated mine life, based on projected production rates.

Land reclamation requirements for the Hycroft Mine may be burdensome and expensive.

Land reclamation requirements are generally imposed on companies with mining operations in order to minimize long-term effects of land disturbance. Reclamation may include requirements to control dispersion of potentially deleterious effluents; treat ground and surface water to drinking water standards; and reasonably re-establish pre-disturbance land forms and vegetation.

In order to carry out reclamation obligations imposed on us in connection with our activities, we must allocate financial resources that might otherwise be spent on further development programs. We have established a provision for our reclamation obligations on the Hycroft Mine property, as appropriate, but this provision may not be adequate. If we are required to carry out unanticipated reclamation work, our financial position could be adversely affected.

The sale of our mineral properties and suspension of acquisition and exploration activities greatly limit our ability to generate new reserves or identify other mineralized materials to replace or expand our current reserves.

Because the Hycroft Mine has a limited life based on proven and probable mineral reserves and resources, we have previously sought to replace and expand our mineral reserves and resources. Identifying promising mining properties is difficult and speculative. As part of our emergence from federal bankruptcy proceedings, pursuant to our plan of reorganization, we sold our remaining exploration properties. The sale of our mineral properties greatly limits our ability to develop or grow our reserves or identify new mineral resources. As a result, our revenues from the future sale of gold and silver may decline, resulting in lower income and reduced growth. Further, we expect to encounter strong competition from other mining companies in connection with the acquisition of properties producing or capable of producing gold and silver.

TABLE OF CONTENTS

Although we have currently suspended our acquisition and exploration activities, if or when those activities are resumed, we will face competition from many of these companies that have greater financial resources than we do. Consequently, we may be unable to replace and expand current ore reserves through the acquisition of new mining properties or interests therein on terms we consider acceptable.

A shortage of equipment and supplies and/or the time it takes such items to arrive at our Hycroft Mine could adversely affect our ability to operate our business.

We are dependent on various supplies and equipment to engage in mining and development operations. The shortage of such supplies, equipment and parts and/or the time it takes such items to arrive at our Hycroft Mine could have a material adverse effect on our ability to carry out our operations and develop the Hycroft Mine, and therefore limit or increase the cost of production. Such shortages could also result in increased construction costs and cause delays in expansion projects.

The inability to obtain soda ash or delays in obtaining soda ash could adversely affect our ability to profitably operate our business.

There are a limited number of suppliers that produce and supply soda ash and to our knowledge, such suppliers do not typically mine soda ash in excess of what they believe they can sell. We have entered into a three-year agreement with a soda ash supplier to provide soda ash for our operations. However, if the contracted supplier cancels the contract, is unable to produce and supply enough soda ash or ceases operations because of the large quantities of soda ash required in our operations, we may have to temporarily stop mining until we can obtain a new contract to purchase soda ash. Further, we cannot provide any assurance as to the costs that we might incur in obtaining soda ash from a substitute supplier which could adversely affect the profitability and cash flow of our mining operations.

Changes in the cost or supply of energy or commodities used in operations may adversely affect the profitability of our operations and our financial condition.

Our mining operation is an intensive user of energy. Our principal energy sources are electricity and diesel fuel. We rely upon third parties for our supply of energy resources consumed in our mining activities. Energy prices can be affected by numerous factors beyond our control, including global and regional supply and demand, political and economic conditions, including the impact of global public health crises such as the spread of the novel coronavirus, COVID-19, on the global economy, and applicable regulatory regimes. The prices of various sources of energy may increase significantly from current levels. An increase in energy prices could materially and adversely affect our results of operations and financial condition.

Disruptions in the supply of our energy resources could temporarily impair our ability to produce gold and silver or delay any expansion projects or plans. Our mining operation is in a remote location requiring the long distance transmission of power. A disruption in the transmission of energy, inadequate energy transmission infrastructure or the termination of any of our energy supply contracts could interrupt our energy supply and adversely affect our operations or expansion projects.

Our production costs are also affected by the prices of commodities we consume or use in our operations, such as diesel fuel, sodium cyanide, soda ash, lime, tires, and explosives. The prices of such commodities are influenced by supply and demand trends affecting the mining industry in general and other factors outside our control. Increases in the price for materials consumed in our mining and production activities could materially and adversely affect our liquidity, results of operations, financial condition and cash flows.

We cannot be certain that our future development activities will be commercially successful.

Substantial expenditures are required to construct additional leach pads to extract gold and silver from our transition and sulfide ore utilizing the new metallurgical processes to extract gold and silver from the transition and sulfide ores described in the Hycroft Technical Report, to further develop our Hycroft Mine to identify new mineral reserves and resources, and to expand or establish mineral reserves and resources through drilling and analysis. We cannot provide assurance that our process to extract gold and silver from transition and sulfide ores using a heap leach process can be maintained on an economic and profitable basis, that any mineral reserves or resources discovered will be in sufficient quantities to justify commercial

TABLE OF CONTENTS

operations or that the funds required for development can be obtained on a timely or economic basis. A number of factors, including costs, actual mineralization, consistency and reliability of ore grades and commodity prices affect successful project development. The efficient operation of processing facilities, the existence of competent operational management, as well as the availability and reliability of appropriately skilled and experienced consultants also can affect successful project development. We can provide no assurance that the development and advancement of the Hycroft Mine sulfide leaching operations will result in economically viable mining operations or yield new mineral reserves or resources.

We may be adversely affected by challenges relating to slope stability.

Our open pit mine gets deeper as we mine it, presenting certain geotechnical challenges including the possibility of slope failure. If we are required to decrease pit slope angles or provide additional road access to prevent such a failure, our stated mineral reserves could be negatively affected. Further, hydrological conditions relating to pit slopes, renewal of material displaced by slope failures and increased stripping requirements could also negatively affect our stated mineral reserves. We cannot provide any assurances that we will not have to take additional action to maintain slope stability in the future or that our actions taken to date will be sufficient. Unexpected failure or additional requirements to prevent slope failure may negatively affect our results of operations and financial condition, as well as have the effect of diminishing our stated ore reserves.

We may need to raise additional capital but such capital may not be available on favorable terms or at all.

The continuing operation of our Hycroft Mine under the new mine plan will require significant investment. Failure to obtain sufficient financing may result in the delay or indefinite postponement of development or production at the Hycroft Mine. The covenants in the Sprott Credit Agreement and the Sprott Royalty Agreement, as well as downgrades to our credit ratings as a result of the bankruptcy proceedings, could significantly limit our ability to secure new or additional credit facilities, increase our cost of borrowing, and make it difficult or impossible to raise additional capital on favorable terms or at all.

Our primary future cash requirements will be to fund working capital as we ramp up operations at the Hycroft Mine and to fund future and sustaining capital. As of December 31, 2019, we had cash and cash equivalents of $6.2 million. Using current metal price levels and our estimates of future metal sales and costs, under our new mine plan described in the Hycroft Technical Report to mine sulfide and transition ore using a heap leach process, we currently expect our future net cash used in investing activities during the fiscal years ending December 31, 2019 and 2020 to exceed our cash flows provided by operating activities during the same periods. You are cautioned that management’s expectations regarding our liquidity and capital resources are based on a number of assumptions that we believe are reasonable but could prove to be incorrect. For example, our expectations are based on assumptions regarding commodity price levels, gold and silver recovery percentages and rates, production estimates, anticipated costs and other factors that are subject to a number of risks, many of which are beyond our control. If our assumptions prove to be incorrect, we may require additional financing sooner than we expect to continue to operate our business, which may not be available on favorable terms or at all and which could have a material adverse effect on our results of operations, financial condition and liquidity.

The Sprott Credit Agreement and Sprott Royalty Agreement will impose significant operating and financial restrictions that may limit our ability to operate our business.

The Sprott Credit Agreement that HYMC will assume, and the Sprott Royalty Agreement that HYMC will enter into, in connection with the business combination will impose significant operating and financial restrictions on us and our restricted subsidiaries. These restrictions will limit our ability and the ability of our restricted subsidiaries to, among other things, as applicable:

•

incur additional debt;

•

pay dividends or make other restricted payments, including certain investments;

•

create or permit certain liens;

•

sell assets;

TABLE OF CONTENTS

•

engage in certain transactions with affiliates; and

•

consolidate or merge with or into other companies, or transfer all or substantially all of our assets or the assets of our restricted subsidiaries.

These restrictions could limit our ability to finance our future operations or capital needs, make acquisitions or pursue available business opportunities.

In addition, the Sprott Credit Agreement and the Sprott Royalty Agreement will require us to comply with a number of customary covenants, including:

•

covenants related to the delivery of monthly, quarterly and annual financial statements, budgets and annual projections;

•

maintaining required insurance;

•

compliance with laws (including environmental);

•

compliance with ERISA;

•

maintenance of ownership of 100% of Hycroft Mine;

•

restrictions on consolidations, mergers or sales of assets;

•

limitations on liens;

•

limitations on issuance of certain equity interests;

•

limitations on issuance of additional indebtedness;

•

limitations on transactions with affiliates; and

•

other customary covenants.

We cannot assure you that we will satisfy these covenants or that our lenders will waive any future failure to do so. A breach of any of the covenants under the Sprott Credit Agreement and the Sprott Royalty Agreement could result in a default. Please see “Description of Certain Indebtedness — Sprott Credit Agreement” and “Description of Certain Indebtedness — Sprott Royalty Agreement” of this joint proxy statement/prospectus for further information. If a default occurs under the Sprott Credit Agreement and the Sprott Royalty Agreement, the lenders could elect to declare the debt, together with accrued interest and other fees, to be immediately due and payable and proceed against the collateral securing that debt, which, in the case of the Sprott Credit Agreement and the Sprott Royalty Agreement, constitutes all or substantially all of HYMC’s assets.

Our substantial indebtedness could adversely affect our financial condition.

After the business combination we will have a significant amount of indebtedness. As of March 31, 2020, we had outstanding indebtedness of $596.4 million, including $125.5 million in aggregate principal amount of indebtedness under the First Lien Credit Agreement, $6.9 million under the Jacobs Note, $105.6 million in aggregate principal amount of indebtedness in outstanding 1.25 Lien Notes, $142.2 million in aggregate principal amount of indebtedness in outstanding 1.5 Lien Notes and $216.2 million in aggregate principal amount of indebtedness in outstanding Second Lien Notes. As a condition to the business combination, the indebtedness under the First Lien Credit Agreement and the Jacobs Note will be repaid, the 1.25 Lien Notes will be exchanged for New Subordinated Notes and up to $80.0 million in aggregate principal amount of New Subordinated Notes will be assumed by HYMC in connection with the business combination, the 1.5 Lien Notes and any Excess Notes will be paid in cash or exchanged for shares of HYMC Class A common stock, the Second Lien Notes will be converted into shares of Seller common stock, HYMC will assume the Sprott Credit Agreement and HYMC and its wholly-owned subsidiary will enter into the Sprott Royalty Agreement. Subject to the limits contained in the Sprott Credit Agreement to be assumed, and the Sprott Royalty Agreement to be entered into, in connection with the consummation of the business combination, if we are able to incur additional debt from time to time to finance working capital, capital expenditures, investments or acquisitions, or for other purposes, then the risks related to our high level of debt could intensify. Our high level of debt and royalty payment obligations could:

TABLE OF CONTENTS

•

make it more difficult for us to satisfy our obligations with respect to our outstanding debt;

•

require a substantial portion of our cash flows to be dedicated to debt service and/or royalty payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions and other general corporate purposes;

•

limit our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate requirements;

•

increase our vulnerability to commodity price volatility, including increases in prices of commodities that we purchase and decreases in prices of gold and silver that we sell, each as part of our operations, general adverse economic and industry conditions;

•

limit our flexibility in planning for and reacting to changes in the industry in which we compete;

•

place us at a disadvantage compared to other, less leveraged competitors; and

•

increase our cost of borrowing.

Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under our debt, and the price of our common stock. The Sprott Credit Agreement to be assumed, and the Sprott Royalty Agreement to be entered into, in connection with the consummation of the business combination, each contain restrictive covenants that limit our ability to engage in activities that may be in our long-term best interest. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could result in the acceleration of nearly all of our debt.

If we default on our obligations to pay any of our indebtedness or otherwise default under the agreements governing our indebtedness, lenders could accelerate such debt and we may be subject to restrictions on the payment of our other debt obligations or cause a cross-acceleration.

Any default under the agreements governing our indebtedness that is not waived by the required lenders or holders of such indebtedness, and the remedies sought by the holders of such indebtedness, could prevent us from paying principal, premium, if any, and interest on other debt instruments. If we are unable to generate sufficient cash flow or are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness and royalty payment obligations, or if we otherwise fail to comply with the various covenants in any agreement governing our indebtedness, we would be in default under the terms of the agreements governing such indebtedness and other indebtedness under the cross-default and cross-acceleration provisions of such agreements. In the event of such default:

•

the lenders or holders of such indebtedness could elect to terminate any commitments thereunder, declare all the funds borrowed thereunder to be due and payable and, if not promptly paid, in the case of our secured debt, institute foreclosure proceedings against our assets; and

•

even if these lenders or holders do not declare a default, they may be able to cause all of our available cash to be used to repay indebtedness owed to them.

As a result of such default and any actions the lenders may take in response thereto, HYMC could be forced into bankruptcy or liquidation.

We may not be able to generate sufficient cash to service all of our indebtedness, and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on our debt and royalty obligations or refinance our debt obligations (if necessary) depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond our control, including the market prices of gold and silver. We may be unable to maintain a level of cash flow from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness and our royalty obligations.

If our cash flows and capital resources are insufficient to fund our debt service obligations and our royalty obligations, we could face substantial liquidity problems and could be forced to reduce or delay

TABLE OF CONTENTS

investments and capital expenditures or to dispose of material assets, seek additional debt or equity capital or restructure or refinance our indebtedness. We may not be able to effect any such alternative measures, if necessary, on commercially reasonable terms or at all and, even if successful, those alternative actions may not allow us to meet our scheduled debt service obligations. The Sprott Credit Agreement to be assumed, and the Sprott Royalty Agreement to be entered into, by HYMC in connection with the consummation of the business combination will restrict our ability to dispose of assets and use the proceeds from those dispositions and may also restrict our ability to raise debt to be used to repay other indebtedness when it becomes due. We may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service and royalty payment obligations then due.

In addition, we conduct a substantial portion of our operations through our subsidiaries, certain of which in the future may not be guarantors of our indebtedness. Accordingly, repayment of our indebtedness is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Unless they are guarantors of our indebtedness, our subsidiaries do not have any obligation to pay amounts due on our indebtedness or to make funds available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness.

Our inability to generate sufficient cash flows to satisfy our debt and royalty obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would materially and adversely affect our financial position and results of operations and our ability to satisfy our obligations.

If we cannot make scheduled payments on our debt, we will be in default and the lenders under the Sprott Credit Agreement to be assumed, and the Sprott Royalty Agreement to be entered into, by HYMC in connection with the consummation of the business combination could foreclose against the assets securing their borrowings and we could be forced into bankruptcy or liquidation.

Our history of operations includes periods of operating and net losses, and we may incur operating and net losses in the future. Our significant net losses and our significant amount of indebtedness led us to declare bankruptcy in 2015.

Prior to our emergence from bankruptcy proceedings on October 22, 2015, we generated operating losses of $368.9 million for period from January 1, 2015 through October 22, 2015 and $480.1 million for the year ended December 31, 2014. In the years ended December 31, 2018 and 2017 we generated operating losses of $8.2 million and $32.9 million, respectively, and net losses of $55.8 million and $74.1 million, respectively. In connection with the restart of operations beginning in 2019, in the year ended December 31, 2019, we generated operating losses of $33.9 million and net losses of $98.9 million. Please see “Seller’s Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations — Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018” and the financial statements for the years ended December 31, 2019 and 2018 included elsewhere in this joint proxy statement/prospectus for more information regarding our results of operations during these periods. If we continue to suffer operating and net losses, our business, financial condition, results of operations and cash flows may be negatively impacted.

Upon the conversion of the Second Lien Notes, the exchange of the 1.5 Lien Notes and Excess Notes and repayment of the First Lien Credit Agreement and the Jacobs Note in connection with the consummation of the business combination, while we will have significantly less indebtedness and interest expense, we will still have material indebtedness. We may not generate sufficient revenues in future periods to cover our payment obligations under the Sprott Credit Agreement and New Subordinated Notes to be assumed, and the Sprott Royalty Agreement to be entered into, in connection with the consummation of the business combination to pay for all of our operating or other expenses, which could have a material adverse effect on our business, results of operations and financial condition.

TABLE OF CONTENTS

The chapter 11 proceedings may have disrupted our business relationships, which may materially and adversely affect our operations.

The chapter 11 reorganization that we went through in 2015 may have created a negative public perception of us in relation to our competitors and adversely impacted our relationships with our employees, suppliers, customers and other parties. Consequently, our relationships with our customers, suppliers, certain liquidity providers and employees may have been adversely impacted and our operations, currently and going forward, could be materially and adversely affected, such as if we are not extended customary business credit or payment terms.

If we lose key personnel or are unable to attract and retain additional personnel, we may be unable to develop our business.

Our development in the future will be highly dependent on the efforts of key management employees, specifically, Randy Buffington, our Executive Chairman and Chief Executive Officer, Stephen Jones, our Executive Vice President and Chief Financial Officer, and other key employees that we may hire in the future. We will need to recruit and retain other qualified managerial and technical employees to build and maintain our operations. If we are unable to successfully recruit and retain such persons, our development and growth could be significantly curtailed.

We are dependent upon information technology systems, which are subject to disruption, damage, failure and risks associated with implementation and integration.

We are dependent upon information technology systems in the conduct of our operations. Our information technology systems are subject to disruption, damage or failure from a variety of sources, including, without limitation, computer viruses, security breaches, cyber-attacks, natural disasters and defects in design. Cybersecurity incidents, in particular, are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, extortion to prevent or the unauthorized release of confidential or otherwise protected information and the corruption of data. Given the unpredictability of the timing, nature and scope of information technology disruptions, we could potentially be subject to production downtimes, operational delays, extortion, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, other manipulation or improper use of our systems and networks or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, financial condition or results of operations.

We could also be adversely affected by system or network disruptions if new or upgraded information technology systems are defective, not installed properly or not properly integrated into our operations. System modification failures could have a material adverse effect on our business, financial position and results of operations and could, if not successfully implemented, adversely impact the effectiveness of our internal controls over financial reporting.

We may be subject to legal proceedings.

Due to the nature of our business, we may be subject to regulatory investigations, claims, lawsuits and other proceedings in the ordinary course of our business. The results of these legal proceedings cannot be predicted with certainty due to the uncertainty inherent in litigation, including the effects of discovery of new evidence or advancement of new legal theories, the difficulty of predicting decisions of judges and juries and the possibility that decisions may be reversed on appeal. We can provide no assurances that these matters will not have a material adverse effect on our business.

For example, our predecessor is currently the subject of a securities class-action lawsuit in Canada, which alleges that our predecessor made false and misleading statements in public disclosures to induce the purported class members to purchase securities at artificially inflated prices. Our predecessor disputes the claims that were brought prior to our filing for federal bankruptcy protection in the chapter 11 cases and will continue to contest such actions.

We are not currently a party to any forward sale or other significant hedging arrangements to protect against gold and silver prices and commodity prices and, as a result, our operating results are exposed to the impact of any significant decrease in the price of gold or silver or any significant increase in commodity prices.

We are not currently a party to any forward sales or other hedging arrangements to reduce the risk of exposure to volatility in commodity prices. Accordingly, our future operations will be exposed to the impact of any significant decrease in gold or silver prices and any significant increase in commodity prices. If such prices adversely change significantly, we will realize reduced revenues and increased costs.

Further, we cannot provide any assurance that the use of hedging techniques will always be to our benefit. Hedging instruments that protect against gold and silver market price volatility may prevent us from realizing the full benefit from subsequent increases in market prices with respect to covered production, which would cause us to record a mark-to-market loss, decreasing our profits. Hedging contracts also are subject to the risk that the other party may be unable or unwilling to perform its obligations under these contracts. Any significant nonperformance could have a material adverse effect on our financial condition, results of operations and cash flows.

Joint ventures and other partnerships may expose us to risks.

In the future, we may enter into joint ventures or other partnership arrangements with other parties in relation to the exploration, development and production of certain properties. Joint ventures can often require unanimous approval of the parties to the joint venture or their representatives for certain fundamental decisions such as an increase or reduction of registered capital, merger, division, dissolution, amendments of constituting documents, and the pledge of joint venture assets, which means that each joint venture party may have a veto right with respect to such decisions which could lead to a deadlock in the operations of the joint venture or partnership. Further, we may be unable to exert control over strategic decisions made in respect of such properties. Any failure of such other companies to meet their obligations to us or to third parties, or any disputes with respect to the parties’ respective rights and obligations, could have a material adverse effect on the joint ventures or their properties and therefore could have a material adverse effect on our results of operations, financial performance and cash flows.

The three largest stockholders of HYMC after the business combination will be able to exert significant influence over matters submitted to stockholders for approval, which could delay or prevent a change in corporate control or result in the entrenchment of management or the HYMC Board, possibly conflicting with the interests of our other stockholders.

Mudrick Capital Management LP, an affiliate of MUDS (“Mudrick Capital”), Whitebox Advisors LLC (“Whitebox”), and Highbridge Capital Management LLC, (“Highbridge”) will beneficially own approximately 33.4%, 23.6% and 13.5% of the outstanding shares of HYMC Class A common stock (including shares of HYMC Class A common stock received upon conversion of the Second Lien Notes and exchange of the 1.5 Lien Notes and the Excess Notes, if any, by each of Mudrick Capital, Whitebox and Highbridge), respectively, upon consummation of the business combination (assuming the maximum redemption scenario). Because of their significant stockholdings, each of Mudrick Capital, Whitebox and Highbridge could exert significant influence in determining the outcome of corporate actions requiring stockholder approval and otherwise influence the HYMC business. This influence could have the effect of delaying or preventing a change in control of HYMC or entrenching HYMC management or the HYMC Board, which could conflict with the interests of other stockholders and, consequently, could adversely affect the market price of HYMC Class A common stock.

Risks Related to MUDS and the Business Combination

MUDS’ initial stockholders have agreed to vote in favor of the business combination, regardless of how MUDS’ public stockholders vote.

Unlike many other blank check companies in which the initial stockholders agree to vote their founder shares in accordance with the majority of the votes cast by the public stockholders in connection with an initial business combination, MUDS’ initial stockholders have agreed to vote any shares of common stock owned by them in favor of the Business Combination Proposal. As of the date hereof, our initial stockholders

TABLE OF CONTENTS

own shares equal to approximately 42.9% of MUDS’ issued and outstanding shares of common stock. Accordingly, it is more likely that the necessary stockholder approval will be received for the business combination than would be the case if the initial stockholders agreed to vote any shares of common stock owned by them in accordance with the majority of the votes cast by the public stockholders.

Sponsor, certain members of the MUDS Board and certain of MUDS’ officers have interests in the business combination that are different from or are in addition to those of other MUDS stockholders in recommending that stockholders vote in favor of approval of the Business Combination Proposal and approval of the other proposals described in this joint proxy statement/prospectus.

In considering the recommendation of the MUDS Board to vote for the proposals presented at the MUDS special meeting, including the Business Combination Proposal, you should be aware that aside from their interests as stockholders, sponsor and certain members of the MUDS Board and officers of MUDS have interests in the business combination that are different from, or in addition to, the interests of MUDS’ stockholders generally. These interests include the fact that investment funds affiliated with and managed by Mudrick Capital, of which Jason Mudrick, Chief Executive Officer and a director of MUDS, is the President and David Kirsch, Vice President and a director of MUDS, is Managing Director, currently hold approximately 648,950 shares of Seller common stock, and, as of March 31, 2020, an aggregate of $41.8 million in principal amount of Seller’s First Lien Notes, an aggregate of $56.7 million in principal amount of Seller’s 1.5 Lien Notes, an aggregate of $83.8 million in principal amount of Seller’s Second Lien Notes and an aggregate of $42.1 million in principal amount of Seller’s 1.25 Lien Notes. In addition, Mudrick Capital has the right to receive any payments made in respect of the phantom shares that were awarded to Mr. Kirsch in his capacity as a non-employee director of the Seller since his appointment to the Seller Board in October 2015, which will result in the payment of approximately $0.5 million in cash to Mudrick Capital in connection with the consummation of the business combination. Mr. Kirsch did not participate as a director in meetings or votes of the Seller Board related to Seller’s consideration of the business combination and alternative transactions unless specifically requested to do so after acknowledgement and disclosure of his potential conflicts of interest. It is anticipated that Mr. Kirsch will remain on the board of directors of HYMC following the closing of the business combination. Mr. Mudrick did not participate in any of the discussions between MUDS and Seller with respect to the business combination or otherwise during the timeframe in which a business combination transaction was being considered between the parties. Mr. Mudrick did, however, in the ordinary course of Mudrick Capital’s investment operations and prior to the commencement of discussions with respect to the business combination, meet with the Seller’s management team and visited the Hycroft Mine in respect of Mudrick Capital’s long-term investment in the Hycroft business. The MUDS Board was aware of and considered these interests, among other matters, in evaluating and negotiating the business combination and transaction agreements and in recommending to MUDS' stockholders that they vote in favor of the proposals presented at the MUDS special meeting, including the Business Combination Proposal. Stockholders should take these interests into account in deciding whether to approve the proposals presented at the MUDS special meeting, including the Business Combination Proposal. Please see the sections “The Business Combination — Interests of Certain Persons in the Business Combination” and “Special Meeting of MUDS Stockholders — Recommendation to MUDS’ Stockholders” beginning on pages [•] and [•], respectively, of this joint proxy statement/prospectus for more information.

Sponsor holds a significant number of shares of MUDS common stock. Sponsor will lose its entire investment in MUDS if a business combination is not completed.

Sponsor currently owns 5,200,000 shares of MUDS Class B common stock, representing approximately 42.9% of the total outstanding shares of MUDS common stock. The MUDS Class B common stock will be worthless if MUDS does not complete an initial business combination by August 12, 2020. In addition, sponsor holds an aggregate of 6,700,000 private placement warrants that will also be worthless if MUDS does not complete a business combination by August 12, 2020. The personal and financial interests of sponsor may have influenced its motivation in completing the business combination and influencing the operating of HYMC after the business combination has been consummation.

TABLE OF CONTENTS

Sponsor, MUDS’ directors or officers or their affiliates may elect to purchase shares from public stockholders, which may influence a vote on a proposed business combination and reduce the public “float” of MUDS Class A common stock.

Sponsor, MUDS’ directors or executive officers or their affiliates may purchase shares in privately negotiated transactions or in the open market either prior to or following the completion of the business combination, although they are under no obligation to do so. Such a purchase may include a contractual acknowledgment that such stockholder, although still the record holder of shares of MUDS Class A common stock, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that sponsor, MUDS’ directors, officers or their affiliates purchase shares in privately negotiated transactions from public stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. The purpose of such purchases could be to vote such shares in favor of the business combination and thereby increase the likelihood of obtaining stockholder approval of the business combination or to satisfy closing conditions in the Purchase Agreement regarding unrestricted and available cash prior to and following the consummation of the business combination where it appears that such requirements would otherwise not be met. This may result in the completion of the business combination that may not otherwise have been possible.

If MUDS is unable to complete an initial business combination, public stockholders may receive only approximately $10.10 per share on the liquidation of the trust account (or less than $10.10 per share in certain circumstances where a third party brings a claim against MUDS that sponsor is unable to indemnify), and MUDS’ warrants will expire worthless.

If MUDS is unable to complete an initial business combination by August 12, 2020, public stockholders may receive only approximately $10.10 per share on the liquidation of the trust account (or less than $10.10 per share in certain circumstances where a third-party brings a claim against MUDS that sponsor is unable to indemnify (as described herein)) and the MUDS’ warrants will expire worthless.

If third parties bring claims against MUDS, the proceeds held in the trust account could be reduced and the per-share redemption amount received by stockholders may be less than $10.10 per share.

MUDS’ placing of funds in the trust account may not protect those funds from third-party claims against it. Although MUDS will seek to have all vendors, service providers (other than MUDS’ independent auditors), prospective target businesses or other entities with which MUDS does business execute agreements with it waiving any right, title, interest or claim of any kind in or to any funds held in the trust account for the benefit of public stockholders, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the trust account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against MUDS’ assets, including the funds held in the trust account. If any third party refuses to execute an agreement waiving such claims to the funds held in the trust account, MUDS’ management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third-party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to it than any alternative.

Examples of possible instances where MUDS may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with MUDS and will not seek recourse against the trust account for any reason. Upon redemption of public shares, if MUDS is unable to complete the business combination within the prescribed timeframe, or upon the exercise of a redemption right in connection with the business combination, MUDS will be required to provide for payment of claims of creditors that were not waived that may be brought against it within the ten years following redemption. Accordingly, the per-share redemption amount received by public shareholders could be less than the $10.10 per share initially held in the trust account, due to claims of such creditors. Sponsor has agreed that it will

TABLE OF CONTENTS

be liable to MUDS if and to the extent any claims by a vendor for services rendered or products sold to MUDS, or a prospective target business with which MUDS has discussed entering into a business combination agreement, reduce the amount of funds in the trust account to below (i) $10.10 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the trust account and except as to any claims under indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, sponsor will not be responsible to the extent of any liability for such third party claims. MUDS has not independently verified whether sponsor has sufficient funds to satisfy its indemnity obligations and MUDS has not asked the sponsor to reserve for such indemnification obligations.

MUDS directors may decide not to enforce the indemnification obligation of sponsor, resulting in a reduction in the amount of funds in the trust account available for distribution to public stockholders.

In the event that the proceeds in the trust account are reduced below the lesser of (i) $10.10 per share and (ii) the actual amount per share held in the trust account as of the date of the liquidation of the trust account if less than $10.10 per share due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, and sponsor asserts that it is unable to satisfy its obligation or that it has no indemnification obligations related to a particular claim, MUDS’ independent directors would determine whether to take legal action against sponsor to enforce its indemnification obligations. While MUDS currently expects that its independent directors would take legal action on MUDS’ behalf against sponsor to enforce its indemnification obligations to us, it is possible that MUDS’ independent directors in exercising their business judgment and subject to their fiduciary duties may choose not to do so in any particular instance. If MUDS’ independent directors choose not to enforce these indemnification obligations, the amount of funds in the trust account available for distribution to public stockholders may be reduced below $10.10 per share.

If, before distributing the proceeds in the trust account to public stockholders, MUDS files a bankruptcy petition or an involuntary bankruptcy petition is filed against MUDS that is not dismissed, the claims of creditors of such proceeding may have priority over the claims of MUDS stockholders and the per-share amount that would otherwise be received by MUDS stockholders in connection with MUDS liquidation may be reduced.

If, before distributing the proceeds in the trust account to public stockholders, MUDS files a bankruptcy petition or an involuntary bankruptcy petition is filed against MUDS that is not dismissed, the proceeds held in the trust account could be subject to applicable bankruptcy law, and may be included in MUDS bankruptcy estate and subject to the claims of third parties with priority over the claims of MUDS stockholders. To the extent any bankruptcy claims deplete the trust account, the per-share amount that would otherwise be received by MUDS stockholders in connection with MUDS liquidation may be reduced.

If, after MUDS distributes the proceeds in the trust account to its public stockholders, MUDS files a bankruptcy petition or an involuntary bankruptcy petition is filed against MUDS that is not dismissed, a bankruptcy court may seek to recover such proceeds, and MUDS and the MUDS Board may be exposed to claims of punitive damages.

If, after MUDS distributes the proceeds in the trust account to its public stockholders, MUDS files a bankruptcy petition or an involuntary bankruptcy petition is filed against MUDS that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover all amounts received by MUDS’ stockholders. In addition, the MUDS Board may be viewed as having breached its fiduciary duty to our creditors and/or having acted in bad faith, thereby exposing itself and us to claims of punitive damages, by paying public stockholders from the trust account prior to addressing the claims of creditors.

TABLE OF CONTENTS

The sponsor, officers and directors will not be eligible to be reimbursed for their out-of-pocket expenses if a business combination is not completed.

At the closing of the business combination, the sponsor, executive officers and directors, or any of their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on MUDS’ behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations. There is no cap or ceiling on the reimbursement of out-of-pocket expenses incurred in connection with activities on MUDS’ behalf. The personal and financial interests of the sponsor, executive officers and directors may influence their motivation in identifying and selecting a target business combination and completing the business combination.

MUDS’ stockholders will experience dilution as a consequence of, among other transactions, the issuance of HYMC Class A common stock as consideration in the business combination, the private investment, the forward purchase, the underwriting commission issuance and the lender issuance. Having a minority share position may reduce the influence that MUDS’ current stockholders have on the management of MUDS.

TABLE OF CONTENTS

The ownership percentages of HYMC set forth in the foregoing tables (a) exclude (1) the shares of HYMC Class A common stock issuable upon the exercise of warrants that will remain outstanding following the business combination, including Seller warrants assumed in the business combination, and (2) any shares of HYMC Class A common stock issuable upon the conversion of mirror replacement equity awards issued to holders of outstanding Seller equity awards in connection with the business combination, and (b) assume (1) the completion of the business combination occurs on April 30, 2020, (2) the issuance of 315,788 shares (in the no redemption scenario) and 6,500,000 shares (in the maximum redemption scenario) of HYMC Class A common stock to the Initial Subscribers in the private placement, for aggregate gross proceeds of $3,157,880 or $65,000,000, respectively, (3) the issuance of 1,000,000 shares (in the no redemption scenario) and 2,000,000 shares (in the maximum redemption scenario) of HYMC Class A common stock in an incremental equity investment for aggregate gross proceeds of $10,000,000 or $20,000,000, respectively, (4) the issuance of 1% of the outstanding shares of HYMC Class A common stock to the Lender pursuant to the Sprott Credit Agreement, (5) that there is no Cash Available for Payment in connection with the consummation of the exchange and that the consideration in the exchange is comprised entirely of the Excess Notes Share Payment and the 1.5 Lien Share Payment, (6) the consummation of the transactions contemplated by the Parent Sponsor Letter Agreement, including the share surrender, on the basis of the assumptions set forth in clause (2) hereof with respect to the private investment, resulting in the surrender of 1,941,667 shares (in the no redemption scenario) or 3,584,616 shares (in the maximum redemption scenario) of MUDS Class B common stock, respectively, (7) the consummation of the underwriting commission issuance, which, on the basis of the assumptions set forth in clauses (b)(2) and (b)(3) hereof, shall result in the issuance of approximately 456,104 shares (in the no redemption scenario) or 237,067 shares (in the maximum redemption scenario) of HYMC Class A common stock, respectively, and (8) that approximately 50,001,241 shares (in the no redemption scenario), 50,057,687 shares (in the maximum redemption scenario) of HYMC Class A common stock are outstanding immediately after consummation of the business combination. For more information, please see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information.” Please see the section entitled Beneficial Ownership of Securities for more information regarding beneficial ownership of MUDS Class A common stock and projected beneficial ownership of HYMC Class A common stock following the consummation of the business combination. Please see the section entitled “The Purchase Agreement and Related Agreements — Related Agreements” beginning on page [•] of this joint proxy statement/prospectus for further details regarding the transactions related to the business combination.

The Class A common stock and public warrants are currently listed on NASDAQ and will be listed on NASDAQ following the business combination. MUDS’ continued eligibility for listing may depend on, among other things, the number of public shares that are redeemed. There can be no assurance that HYMC will be able to comply with the continued listing standards of NASDAQ. If, after the business combination, NASDAQ delists HYMC Class A common stock from trading on its exchange for failure to meet the listing standards, HYMC’s stockholders could face significant material adverse consequences including:

•

a limited availability of market quotations for HYMC’s securities;

•

reduced liquidity for HYMC’s securities;

•

a determination that HYMC Class A common stock is a “penny stock” which will require brokers trading in HYMC Class A common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for HYMC’s securities;

•

a limited amount of news and analyst coverage; and

•

a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because MUDS Class A common stock and public warrants are listed on NASDAQ, they are covered securities. Although the states are preempted from regulating the sale of MUDS’ securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. While MUDS is not aware of a state, other than the state of Idaho, having used these powers to prohibit or restrict the sale of securities issued by blank check companies, certain state securities regulators view blank

TABLE OF CONTENTS

check companies unfavorably and might use these powers, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if the shares were no longer listed on NASDAQ, MUDS’ securities would not be covered securities and MUDS would be subject to regulation in each state in which MUDS offers securities.

A significant portion of HYMC Class A common stock following the business combination will be restricted from immediate resale, but may be sold into the market in the future. This could cause the market price of HYMC Class A common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of common stock in the public market could occur at any time following the consummation of the business combination. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of HYMC Class A common stock.

the business combination, including Seller warrants assumed in the business combination, and (2) any shares of HYMC Class A common stock issuable upon the conversion of mirror replacement equity awards issued to holders of outstanding Seller equity awards in connection with the business combination, and (b) assume (1) the completion of the business combination occurs on April 30, 2020, (2) the issuance of 315,788 shares (in the no redemption scenario) and 6,500,000 shares (in the maximum redemption scenario) of HYMC Class A common stock to the Initial Subscribers in the private placement, for aggregate gross proceeds of $3,157,880 or $65,000,000, respectively, (3) the issuance of 1,000,000 shares (in the no redemption scenario) and 2,000,000 shares (in the maximum redemption scenario) of HYMC Class A common stock in an incremental equity investment for aggregate gross proceeds of $10,000,000 or $20,000,000, respectively, (4) the issuance of 1% of the outstanding shares of HYMC Class A common stock to the Lender pursuant to the Sprott Credit Agreement, (5) that there is no Cash Available for Payment in connection with the consummation of the exchange and that the consideration in the exchange is comprised entirely of the Excess Notes Share Payment and the 1.5 Lien Share Payment, (6) the consummation of the transactions contemplated by the Parent Sponsor Letter Agreement, including the share surrender, on the basis of the assumptions set forth in clause (2) hereof with respect to the private investment, resulting in the surrender of 1,941,667 shares (in the no redemption scenario) or 3,584,616 shares (in the maximum redemption scenario) of MUDS Class B common stock, respectively, (7) the consummation of the underwriting commission issuance, which, on the basis of the assumptions set forth in clauses (b)(2) and (b)(3) hereof, shall result in the issuance of approximately 456,104 shares (in the no redemption scenario) or 237,067 shares (in the maximum redemption scenario) of HYMC Class A common stock, respectively, and (8) that approximately 50,001,241 shares (in the no redemption scenario) and 50,057,687 shares (in the maximum redemption scenario) of HYMC Class A common stock are outstanding immediately after consummation of the business combination. For more information, please see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information.” Please see the section entitled Beneficial Ownership of Securities for more information regarding beneficial ownership of MUDS Class A common stock and projected beneficial ownership of HYMC Class A common stock following the consummation of the business combination. Please see the section entitled “The Purchase Agreement and Related Agreements — Related Agreements” beginning on page [•] of this joint proxy statement/prospectus for further details regarding the transactions related to the business combination.

At the consummation of the business combination, HYMC and the restricted stockholders will enter into an Amended and Restated Registration Rights Agreement, pursuant to which such stockholders will be entitled to, among other things, customary registration rights, including demand, piggy-back and shelf registration rights, subject to cut-back provisions. HYMC may be required to register up to approximately 47 million shares of HYMC Class A common stock pursuant to the Amended and Restated Registration Rights Agreement. The restricted stockholders will agree not to sell, transfer, pledge or otherwise dispose of shares of HYMC Class A common stock they hold or receive for certain time periods, ranging from between 30 days after the consummation of the business combination for shares purchased in the private investment to six months for shares received in the exchange, to one year after the consummation of the business combination for founder shares, subject to certain exceptions.

MUDS has no operating history and is subject to a mandatory liquidation and subsequent dissolution requirement. As such, there is a risk that MUDS will be unable to continue as a going concern if MUDS does not consummate an initial business combination by August 12, 2020. If MUDS is unable to effect a business combination by August 12, 2020, MUDS will be forced to liquidate and its warrants will expire worthless.

MUDS is a blank check company, and as MUDS has no operating history and is subject to a mandatory liquidation and subsequent dissolution requirement, there is a risk that it will be unable to continue as a going concern if MUDS does not consummate an initial business combination by August 12, 2020. If MUDS does not complete an initial business combination by August 12, 2020, it will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account including interest not previously released to MUDS to fund its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to

TABLE OF CONTENTS

the approval of MUDS’ remaining stockholders and the MUDS Board, dissolve and liquidate, subject in each case to our obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including trust account assets) will be less than the initial public offering price per public unit in the IPO. In addition, if MUDS fails to complete an initial business combination by August 12, 2020, there will be no redemption rights or liquidating distributions with respect to MUDS public warrants or the private placement warrants, which will expire worthless.

MUDS and Seller have incurred and expect to incur significant costs associated with the business combination. Whether or not the business combination is completed, the incurrence of these costs will reduce the amount of cash available to be used for other corporate purposes by MUDS if the business combination is not completed.

MUDS and Seller expect to incur significant costs associated with the business combination. Even if the business combination is not completed, MUDS expects to incur approximately $[•] million in unreimbursed expenses. These expenses will reduce the amount of cash available to be used for other corporate purposes by MUDS if the business combination is not completed.

Even if MUDS consummates the business combination, there is no guarantee that the public warrants will ever be in the money, and they may expire worthless and the terms of MUDS’ warrants may be amended.

The exercise price for MUDS public warrants is $11.50 per shares of MUDS Class A common stock. There is no guarantee that the public warrants will ever be in the money prior to their expiration, and as such, the warrants may expire worthless.

MUDS’ ability to successfully effect the business combination and to be successful thereafter will be dependent upon the efforts of MUDS’ key personnel, including the key personnel of the Hycroft business whom MUDS expects to stay with the Hycroft business following the business combination. The loss of key personnel could negatively impact the operations and profitability of HYMC’s post-combination business and its financial condition could suffer as a result.

MUDS’ ability to successfully effect the business combination is dependent upon the efforts of certain key personnel, including the key personnel of the Hycroft business. Although some of MUDS’ key personnel may remain with HYMC in advisory positions following the business combination, it is possible that HYMC will lose some key personnel, the loss of which could negatively impact the operations and profitability of HYMC’s post-combination business. HYMC anticipates that all of the management of the Hycroft business will remain in place.

HYMC’s success depends to a significant degree upon the continued contributions of senior management, certain of whom would be difficult to replace. Departure by certain of the Hycroft business’ officers could have a material adverse effect on HYMC’s business, financial condition, or operating results. Seller does not maintain key-man life insurance on any of its officers. The services of such personnel may not continue to be available to HYMC.

MUDS and the Hycroft business will be subject to business uncertainties and contractual restrictions while the business combination is pending.

Uncertainty about the effect of the business combination on employees and third parties may have an adverse effect on MUDS and the Hycroft business. These uncertainties may impair MUDS or the Hycroft business’ ability to retain and motivate key personnel and could cause third parties that deal with any of us or them to defer entering into contracts or making other decisions or seek to change existing business relationships. If key employees depart because of uncertainty about their future roles and the potential complexities of the business combination, MUDS or the Hycroft business could be harmed.

MUDS may waive one or more of the conditions to the business combination.

MUDS may agree to waive, in whole or in part, one or more of the conditions to MUDS’ obligations to complete the business combination, to the extent permitted by MUDS’ current certificate of incorporation and bylaws and applicable laws. For example, it is a condition to MUDS’ obligations to close the business

combination that Seller have performed and complied in all material respects with the obligations required to be performed or complied with by Seller under the Purchase Agreement. However, if the MUDS Board determines that a breach of this obligation is not material, then the MUDS Board may elect to waive that condition and close the business combination. MUDS may not waive the condition that MUDS stockholders approve the business combination. Please see the section entitled “The Purchase Agreement and Related Agreements — Conditions to Closing of the Business Combination” of this joint proxy statement/prospectus for additional information.

The exercise of discretion by MUDS’ directors and officers in agreeing to changes to the terms of or waivers of closing conditions in the Purchase Agreement may result in a conflict of interest when determining whether such changes to the terms of the Purchase Agreement or waivers of conditions are appropriate and in the best interests of MUDS’ stockholders.

In the period leading up to the consummation of the business combination, other events may occur that, pursuant to the Purchase Agreement, would require MUDS to agree to amend the Purchase Agreement, to consent to certain actions or to waive rights that it is entitled to under those agreements. Such events could arise because of changes in the course of the Hycroft business, a request by Seller or Seller’s management to undertake actions that would otherwise be prohibited by the terms of the Purchase Agreement or the occurrence of other events that would have a material adverse effect on the Hycroft business and would entitle MUDS to terminate the Purchase Agreement. In any of such circumstances, it would be in the discretion of MUDS, acting through the MUDS Board, to grant its consent or waive its rights. The existence of the financial and personal interests of the directors described elsewhere in this joint proxy statement/prospectus may result in a conflict of interest on the part of one or more of the directors between what he or she may believe is best for MUDS and MUDS stockholders and what he or she may believe is best for himself or herself or his or her affiliates in determining whether or not to take the requested action. As of the date of this joint proxy statement/prospectus, MUDS does not believe there will be any changes or waivers that MUDS’ directors and officers would be likely to make after stockholder approval of the business combination has been obtained. While certain changes could be made without further stockholder approval, if there is a change to the terms of the business combination that would have a material impact on the stockholders, MUDS will be required to circulate a new or amended joint proxy statement/prospectus or supplement thereto and resolicit the vote of MUDS’ stockholders with respect to the Business Combination Proposal.

MUDS will incur significant transaction and transition costs in connection with the business combination.

MUDS has incurred and expects to incur significant, non-recurring and unreimbursable costs in connection with consummating the business combination and operating as a public company following the consummation of the business combination. MUDS may incur additional costs to retain key employees. Except for certain expenses reimbursable by Seller pursuant to the Reimbursement and Exclusivity Agreement, all expenses incurred in connection with the Purchase Agreement and the transactions contemplated thereby, including all legal, accounting, consulting, investment banking and other fees, expenses and costs, will be for the account of the party incurring such fees, expenses and costs.

MUDS’ unreimbursed transaction expenses as a result of the business combination are currently estimated at approximately $[•] million.

If MUDS is unable to complete an initial business combination, MUDS’ warrants may expire worthless.

If MUDS’ due diligence investigation of the Hycroft business was inadequate, then stockholders of HYMC following the business combination could lose some or all of their investment.

Even though MUDS conducted a due diligence investigation of the Hycroft business, MUDS cannot be sure that this diligence uncovered all material issues that may be present inside the Hycroft business, or that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of the Hycroft business and outside of its control will not later arise.

TABLE OF CONTENTS

Following the consummation of the business combination, HYMC’s only significant asset will be its ownership interest in the Hycroft business and such ownership may not be sufficiently profitable or valuable to enable HYMC to pay any dividends on HYMC Class A common stock or satisfy HYMC’s other financial obligations.

Following the consummation of the business combination, HYMC will have no direct operations and no significant assets other than its ownership interest in the Hycroft business. HYMC will depend on the Hycroft business for distributions, loans and other payments to generate the funds necessary to meet its financial obligations, including its expenses as a publicly traded company and to pay any dividends with respect to HYMC Class A common stock. Obligations under the Sprott Credit Agreement, the Sprott Royalty Agreement and the Assumed New Subordinated Notes and the financial condition and operating requirements of the Hycroft business may limit HYMC’s ability to obtain cash from the Hycroft business. The earnings from, or other available assets of, the Hycroft business may not be sufficient to pay dividends or make distributions or loans to enable HYMC to pay any dividends on the common stock or satisfy its other financial obligations.

Please see the sections titled “MUDS’ Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources,” “Seller’s Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources,” and “Description of Certain Indebtedness” beginning on pages [•], [•] and [•], respectively, of this joint proxy statement/prospectus for more information

The HYMC charter that will be effective following the completion of the business combination designate the Court of Chancery of the State of Delaware, to the fullest extent permitted by law, as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by HYMC stockholders, which could limit the ability of HYMC stockholders to obtain a favorable judicial forum for disputes with HYMC or with directors, officers or employees of HYMC and may discourage stockholders from bringing such claims.

Under the HYMC charter that will be effective following the completion of the business combination, unless HYMC consents in writing to the selection of an alternative forum, the sole and exclusive forum will be the Court of Chancery of the State of Delaware for:

•

any derivative action or proceeding brought on behalf of HYMC;

•

any action asserting a claim of breach of a fiduciary duty owed by, or any wrongdoing by, any director, officer or employee of HYMC to HYMC or HYMC’s stockholders;

•

any action asserting a claim arising pursuant to any provision of the DGCL, the certificate of incorporation (including as it may be amended from time to time), or the bylaws;

•

any action to interpret, apply, enforce or determine the validity of the certificate of incorporation or the bylaws; or

•

any action asserting a claim governed by the internal affairs doctrine, in each case, except for, (1) any action as to which the Court of Chancery determines that there is an indispensable party not subject to the personal jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten (10) days following such determination) and (2) any action asserted under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, or, in each case, the rules and regulations promulgated thereunder, for which there is exclusive federal or concurrent federal and state jurisdiction.

These provisions of the HYMC charter could limit the ability of HYMC stockholders to obtain a favorable judicial forum for certain disputes with HYMC or with its directors, officers or other employees, which may discourage such lawsuits against HYMC and its directors, officers and employees. Alternatively, if a court were to find these provisions of the HYMC charter inapplicable to, or unenforceable in respect of, one or more of the types of actions or proceedings listed above, HYMC may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect its business, financial condition and results of operations.

TABLE OF CONTENTS

Sponsor and the Initial Subscribers will beneficially own a significant equity interest in HYMC and may take actions that conflict with your interests.

The interests of sponsor and the Initial Subscribers may not align with the interests of HYMC and its other stockholders. Sponsor and the Initial Subscribers are each in the business of making investments in companies and may acquire and hold interests in businesses that compete directly or indirectly with HYMC. Sponsor and the Initial Subscribers, and their respective affiliates, may also pursue acquisition opportunities that may be complementary to HYMC’s business and, as a result, those acquisition opportunities may not be available to us. HYMC’s proposed charter provides that the Initial Subscribers may engage in competitive businesses and renounces any entitlement to certain corporate opportunities offered to the Initial Subscribers or any of their managers, officers, directors, equity holders, members, principals, affiliates and subsidiaries (other than HYMC and its subsidiaries) that are not expressly offered to them in their capacities as directors or officers of HYMC. The proposed charter also provides that the Initial Subscribers or any of their managers, officers, directors, equity holders, members, principals, affiliates and subsidiaries (other than HYMC and its subsidiaries), do not have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as HYMC or any of its subsidiaries.

Subsequent to the completion of the business combination, HYMC may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on HYMC’s financial condition, results of operations and HYMC’s stock price, which could cause you to lose some or all of your investment.

Although MUDS has conducted due diligence on the Hycroft business, MUDS cannot assure you that this diligence will surface all material issues that may be present in such business, that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of the Hycroft business and outside of MUDS’ and Seller’s control will not later arise. As a result of these factors, HYMC may be forced to later write-down or write-off assets, restructure operations, or incur impairment or other charges that could result in losses. Even if MUDS’ due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with MUDS’ preliminary risk analysis. Even though these charges may be non-cash items and not have an immediate impact on HYMC’s liquidity, the fact that HYMC charges of this nature could contribute to negative market perceptions about HYMC or its securities. Accordingly, any of MUDS’ stockholders who choose to remain stockholders of HYMC following the business combination could suffer a reduction in the value of their shares. Such stockholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by MUDS’ officers or fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that this joint proxy statement/prospectus relating to the business combination contained an actionable material misstatement or material omission.

MUDS has no operating or financial history and MUDS’ results of operations may differ significantly from the unaudited pro forma financial data included in this joint proxy statement/prospectus.

MUDS is a blank check company and MUDS has no operating history and no revenues. This joint proxy statement/prospectus includes unaudited pro forma condensed combined financial statements for MUDS. The unaudited pro forma condensed combined statement of operations of MUDS combines the historical audited results of operations of MUDS for the year ended December 31, 2019, with the historical audited results of operations of Seller for the year ended December 31, 2019, and gives pro forma effect to the business combination as if it had been consummated on January 1, 2019.

The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only, are based on certain assumptions, address a hypothetical situation and reflect limited historical financial data. Therefore, the unaudited pro forma condensed combined financial statements are not necessarily indicative of the results of operations and financial position that would have been achieved had the business combination been consummated on the dates indicated above, or the future consolidated results of operations or financial position of MUDS. Accordingly, MUDS’ business, assets, cash flows, results of operations and financial condition may differ significantly from those indicated by the unaudited pro forma condensed combined financial statements included in this document. For more information,

Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of HYMC’s income or other tax returns could adversely affect HYMC’s financial condition and results of operations.

HYMC will be subject to income taxes in the United States, and HYMC’s domestic tax liabilities will be subject to the allocation of expenses in differing jurisdictions. HYMC’s future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:

•

changes in the valuation of HYMC’s deferred tax assets and liabilities;

•

expected timing and amount of the release of any tax valuation allowances;

•

tax effects of stock-based compensation;

•

costs related to intercompany restructurings;

•

changes in tax laws, regulations or interpretations thereof; and

•

lower than anticipated future earnings in jurisdictions where HYMC has lower statutory tax rates and higher than anticipated future earnings in jurisdictions where HYMC has higher statutory tax rates.

In addition, HYMC may be subject to audits of HYMC’s income, sales and other taxes by U.S. federal, state, local and non-U.S. taxing authorities. Outcomes from these audits could have an adverse effect on HYMC’s financial condition and results of operations.

A market for HYMC’s securities may not continue, which would adversely affect the liquidity and price of HYMC’s securities.

Following the business combination, the price of HYMC’s securities may fluctuate significantly due to the market’s reaction to the business combination and general market and economic conditions. An active trading market for HYMC’s securities following the business combination may never develop or, if developed, it may not be sustained. In addition, the price of HYMC’s securities after the business combination can vary due to general economic conditions and forecasts, HYMC’s general business condition and the release of HYMC’s financial reports. Additionally, if HYMC’s securities become delisted from NASDAQ for any reason, and are quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities that is not a national securities exchange, the liquidity and price of HYMC’s securities may be more limited than if HYMC was quoted or listed on NASDAQ or another national securities exchange. You may be unable to sell your securities unless a market can be established or sustained.

If the business combination’s benefits do not meet the expectations of investors, stockholders or financial analysts, the market price of HYMC’s securities may decline.

If the benefits of the business combination do not meet the expectations of investors, stockholders or securities analysts, the market price of MUDS’ securities following the consummation of the business combination may decline. The market values of MUDS’ securities at the time of the business combination may vary significantly from their prices on the date the Purchase Agreement was executed, the date of this joint proxy statement/prospectus, or the date on which MUDS’ stockholders vote on the business combination.

In addition, following the business combination, fluctuations in the price of HYMC’s securities could contribute to the loss of all or part of your investment. Immediately prior to the business combination, there has not been a public market for Seller’s stock and trading in shares of MUDS Class A common stock has not been active. Accordingly, the valuation ascribed to the Hycroft business and MUDS Class A common stock in the business combination may not be indicative of the price that will prevail in the trading market following the business combination.

The trading price of the HYMC Class A common stock following the business combination may fluctuate substantially and may be lower than current price. This may be especially true for companies like
