Organization, Consolidation and Presentation of Financial Statements [Abstract]
Company Overview	Company Overview Hycroft Mining Holding Corporation (formerly known as Mudrick Capital Acquisition Corporation (“MUDS”)) and its subsidiaries (collectively, “Hycroft”, the “Company”, “we”, “us”, “our”, “it”, “HYMC”) is a U.S.-based gold and silver company that is focused on exploring and developing its wholly owned Hycroft Mine in a safe, environmentally responsible, and cost-effective manner. The Hycroft Mine is located in the State of Nevada and the corporate office is located in Winnemucca, Nevada. The Company restarted pre-commercial scale open pit mining operations at the Hycroft Mine during the second quarter of 2019 and began producing and selling gold and silver during the third quarter of 2019. The Company’s operating plan until November 2021 was primarily focused on developing the novel two-stage heap oxidation and leach process (“Novel Process”) detailed in the Hycroft Technical Report Summary (“TRS”), Heap Leaching Feasibility Study, prepared in accordance with the requirements of the Modernization of Property Disclosures for Mining Registrants (“Modernization Rules”), with an effective date of July 31, 2019 (“2019 Hycroft TRS”). Subsequent to November 2021, the Company’s operating plan has been focused on advancing evaluations and developing technical studies for milling sulfide ore through a well-established and proven pressure oxidation process (“POX”). Additionally, as announced on November 10, 2021, as a result of the then current and expected ongoing cost pressures for many of the reagents and consumables used at the Hycroft Mine, and the timeline for completing the updated technical studies in early 2022, the Company discontinued pre-commercial scale mining at its run-of-mine (“ROM”) operation. The Company will continue producing gold and silver from the drain down solutions as long as it is economic which is currently expected to continue through the end of 2022. In February 2022, Hycroft, along with its third-party consultants, completed and filed the Initial Assessment Technical Report Summary for the Hycroft Mine (“2022 Hycroft TRS”) which included a mineral resource estimate utilizing a POX process for sulfide mineralization and heap leaching process for oxide and transition mineralization. The Company will continue to build on the work to date and investigate opportunities identified through progressing the technical and data analyses leading up to the 2022 Hycroft TRS and will provide an updated technical report at an appropriate time. In the first quarter of 2022, the Company completed an equity private placement and an at-the-market public offering program (“ATM Program”) that raised gross proceeds of $194.4 million before issuance costs. The Company plans to use a portion of the proceeds from these equity offerings to conduct additional exploration that will focus on the higher-grade opportunities identified during 2021 exploration drilling and a systematic approach to develop a better understanding of the Hycroft Mine deposit, including potential feeder systems.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation These condensed consolidated interim financial statements of the Company have been prepared, without audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, these condensed consolidated financial statements do not include all information and footnotes necessary for a comprehensive presentation of financial position, results of operations, or cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2021. The Company continues to follow the accounting policies set forth in those audited consolidated financial statements with updates discussed below. In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements include all adjustments that are necessary for a fair presentation of the Company’s interim financial position, operating results, and cash flows for the periods presented. Liquidity As of September 30, 2022, the Company had available unrestricted cash on hand of $153.4 million and net working capital of $155.2 million which is expected to provide it with the necessary liquidity to fund its operating and investing requirements and future obligations as they become due within the next twelve months from the date of this filing. While the Company has continued to process gold and silver ore on the leach pads and in the drain down solutions to partially offset the cash that is projected to be used in its operations and investing activities, the Company does not expect to generate net positive cash from operations for the foreseeable future. Accordingly, the Company will be dependent on its unrestricted cash and other sources of cash to fund its business. As discussed in Note 14 - Stockholders’ Equity, the Company raised gross proceeds of $194.4 million in March 2022 through the following equity financings: • On March 14, 2022, the Company entered into subscription agreements with American Multi-Cinema, Inc. (“AMC”) and 2176423 Ontario Limited, an entity affiliated with Eric Sprott, pursuant to which the Company agreed to sell an aggregate of 46,816,480 units at a purchase price of $1.193 per unit for total gross proceeds, before deduction of fees and expenses, of $55.9 million. • On March 15, 2022, the Company implemented an ATM pursuant to which the Company registered the offer and sale from time to time of its common stock having an aggregate offering price of up to $500.0 million of gross proceeds. Under the ATM Program, which was completed on March 25, 2022, the Company sold 89,553,584 shares of common stock for gross proceeds, before commissions and offering expenses, of $138.6 million. Also, as discussed in Note 10 - Debt, Net , as a result of the equity financings above, the Company reached an agreement with Sprott Private Resource Lending II (Collector), LP (the “Lender”) with respect to the Credit Agreement among Hycroft Mining Holding Corporation, as borrower, Autar Gold Corporation, MUDS, MUDS Holdco Inc., Allied VGH LLC, Hycroft Resources and Development, LLC, Sprott Private Resource Lending II (Collector) Inc., and Sprott Resources Lending Corp. (“Sprott Credit Agreement”), which required the Company to prepay principal under the facility in the amount of $10.0 million following the Company’s receipt of the $55.9 million cash proceeds discussed above. The Company also made an additional prepayment of $13.9 million on March 30, 2022. In addition to the above equity financings, the Company will continue to evaluate alternatives to raise additional capital necessary to fund the future exploration and development of the Hycroft Mine and will continue to explore other strategic initiatives to enhance stockholder value. Historically, the Company has been dependent on various forms of debt and equity financing to fund its business. While the Company has been successful in the past raising funds through equity and debt financings, no assurance can be given that additional financing will be available to it in amounts sufficient to meet the Company’s needs or on terms acceptable to the Company. In the event that funds are not available, the Company may be required to materially change its business plans. Use of estimates The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in these condensed consolidated financial statements and accompanying notes. The more significant areas requiring the use of management estimates and assumptions relate to: recoverable gold and silver ounces on leach pads and in-process inventories; timing of near-term ounce production and related sales; the useful lives of long-lived assets; estimates of mineral resources; estimates of life-of-mine production timing, volumes, costs and prices; future mining and current and future processing plans; environmental reclamation and closure costs and timing; deferred taxes and related valuation allowances; estimates of the fair value of liability classified warrants, and estimates of fair value for asset impairments and financial instruments. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable at the time the estimate is made. Actual results may differ from amounts estimated in these condensed consolidated financial statements, and such differences could be material. Accordingly, amounts presented in these condensed consolidated financial statements are not indicative of results that may be expected for future periods. Cash and cash equivalents During the third quarter of 2022, the Company invested in the AAAm rated US Government Money Market Funds that are readily convertible to cash and, as such, the Company has included them in Cash and cash equivalents . As of December 31, 2021, cash consisted of cash balances. The Company has not experienced any losses on cash balances and believes that no significant risk of loss exists with respect to its cash. Recently adopted accounting pronouncements In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU 2020-06 simplifies guidance on accounting for convertible instruments and contracts in an entity’s own equity including calculating diluted earnings per share. For emerging growth companies, the new guidance is effective for annual periods beginning after December 15, 2022. The Company early adopted ASU 2020-06 as of January 1, 2022, with no material impact on its condensed consolidated financial statements or the related disclosures. In December of 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), as part of its overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. Amendments include removal of certain exceptions to the general principles of ASC 740, Income Taxes and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. For emerging growth companies, the new guidance was effective for annual periods beginning after December 15, 2021 and the Company adopted ASU 2019-12 as of January 1, 2022, with no material impact on its condensed consolidated financial statements or the related disclosures. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force) . ASU 2021-04 clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options ( e.g., warrants) that remain equity classified after modification or exchange.

In addition, the Company’s obligations: (i) to prepay principal with proceeds of asset sales will be credited/offset by the aggregate amount of Initial Equity Proceeds Prepayment and the Subsequent Equity Proceeds Prepayments ($23.9 million); and (ii) to maintain a minimum amount of Unrestricted Cash (as defined in the Second A&R Agreement) was increased to $15.0 million. The Company: (i) paid the previously deferred additional interest of $0.5 million; (ii) made the Initial Equity Proceeds Prepayment of $10.0 million and paid in-kind a $3.3 million fee in connection with the modification and capitalized it to principal on March 16, 2022; and (iii) made the Subsequent Equity Proceeds Prepayment of $13.9 million on March 30, 2022. The Company accounted for the Second A&R Agreement as a debt modification as the Second A&R Agreement did not result in debt that was substantially different. Amendment to the 10% Senior Secured Notes and Note Exchange Agreement On March 14, 2022, the Company entered into an amendment to the 10% Senior Secured Notes and Note Exchange Agreement (the “Note Amendment”), with: (i) certain direct and indirect subsidiaries of the Company as Guarantors; (ii) holders of the 10% Senior Secured Notes (the “Subordinated Notes”), including certain funds affiliated with, or managed by, Mudrick Capital Management, L.P, Whitebox Advisors, LLC, Highbridge Capital Management, LLC, and Aristeia Capital, LLC (collectively, the “Amending Holders”); and (iii) Wilmington Trust, National Association, in its capacity as collateral agent.

The Amending Holders constituted all of the holders of the Subordinated Notes. The Note Amendment became effective upon the closing of a private placement upon receipt of $55.9 million gross cash proceeds (before deduction of fees and expenses). The Company accounted for the Note Amendment as a debt modification as the Note Amendment did not result in debt that was substantially different. The Company incurred a $1.8 million liability management fee attributable to the completion of the Note Amendment. As the Note Amendment was accounted for as a debt modification, the $1.8 million paid to a third-party was charged to General and administrative.

The Certificate of Incorporation Amendment became effective upon filing of the Certificate of Incorporation Amendment with the Delaware Secretary of State on April 22, 2022, 20 days after the Company commenced distribution of an Information Statement on Schedule 14C to the stockholders of the Company. Common Stock Private placement offering On March 14, 2022, the Company entered into subscription agreements with AMC and 2176423 Ontario Limited pursuant to which the Company agreed to sell the entities an aggregate of 46,816,480 units at a purchase price per unit of $1.193 with each unit consisting of one share of the Company’s common stock and one warrant to purchase a share of Common Stock (“Warrants”) and the shares issuable upon exercise of the Warrants (the “Warrant Shares”), providing for a total purchase price of approximately $55.9 million (the “Private Placement Offering”).

On March 15, 2022, the Private Placement Offering closed and the Company received gross proceeds of $55.9 million before deducting expenses incurred in connection with therewith. Net proceeds were $53.6 million, after deducting legal and other fees of $2.3 million (including a non-cash $1.8 million financial advisor fee related to the Private Placement Offering discussed under Settlement fee below). At-the-market offering On March 15, 2022, the Company implemented an “at-the-market” offering (“ATM Program”) by entering into an At Market Issuance Sales Agreement with B. Riley Securities, Inc. (“Sales Agreement”). Under the terms of the Sales Agreement, the Company may from time to time to or through the Agent, acting as sales agent or principal, offer and sell shares of its Class A common stock, par value $0.0001 per share, having a gross sales price of up to $500.0 million.

The Company terminated the ATM Program on March 25, 2022, and received total gross proceeds, before deducting fees and expenses of the ATM Program, of $138.6 million from the sale of 89,553,584 shares of the Company’s common stock. Net proceeds, after deducting commissions and fees of $5.0 million were $133.5 million.

During March 2022, the Company completed the Private Placement Offering, the ATM Program and entered into the Second A&R Agreement and Note Amendment without assistance from the financial advisor. As the Company completed the aforementioned equity and debt transactions during the engagement period, the Company and the financial advisor agreed to a fee of $3.5 million of which 50% is related to liability management for the Note Amendment and 50% is attributable to the Private Placement Offering. On July 26, 2022, the Company executed this settlement agreement and the engagement was terminated with no future obligations. The Company agreed to pay $1.75 million in cash and issue shares of common stock under a private placement for the remaining $1.75 million. The Company issued 1,714,678 shares of common stock on July 28, 2022 and remitted the cash payment on August 1, 2022. The number of shares of common stock issued was determined using the volume weighted average price on the Nasdaq Capital Market for the ten trading days preceding the effective date of the settlement agreement. Salary continuation payments The Company entered into separation agreements with former executives that provide for, among other things, continuation of such former executives’ salaries and certain benefits for periods of 12-24 months from the date of separation. On October 6, 2021, the Company entered in a Waiver and Amendment to the Transition and Succession Agreement and Consulting Agreement with a former employee. The Waiver and Amendment amends the Transition and Succession Agreement and the Consulting Agreement between the Company and the employee, dated July 1, 2020. The Waiver and Amendment terminated the remaining unpaid cash payments to the employee pursuant to the Transition and Succession Agreement and Consulting Agreement in the aggregate amount of $0.7 million, in exchange for the issuance of an aggregate of up to 275,000 shares of the Company's common stock, of which 137,500 was issued on October 8, 2021 and 137,500 shares issued on June 30, 2022.

The Warrants are deemed freestanding, equity-linked financial instructions that do not require liability classification under ASC Topic 480-10 Overall Debt because: (1) they are not mandatory redeemable shares; (2) they do not obligate the Company to buy back shares; and (3) they are not settled in a variable number of shares. As a result, the Company allocated the gross proceeds of $55.9 million from the Private Placement Offering between the Warrants and common stock as of the closing date of March 15, 2022. The Company used the Black-Scholes option pricing model to determine the fair value of the Warrants upon the issuance date using the following assumptions: As of March 15, 2022 Expected term (years) 5 Risk-free interest rate 2.1 % Expected volatility 118.4 % Expected dividend yield — The following table summarizes additional information on the Company’s outstanding warrants as of September 30, 2022: Exercise price Exercise period Expiration date Warrants outstanding Equity classified warrants 5-Year Public Warrants $ 11.50 5 years May 29, 2025 24,886,269 Public Offering Warrants $ 10.50 5 years October 6, 2025 9,583,334 Private Placement Offering Warrants $ 1.068 5 years March 15, 2027 46,816,480

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Performance and Incentive Pay Plan (“PIPP”) On June 2, 2022, the Company’s stockholders approved an amendment to the PIPP which increased the number of authorized shares of common stock available for issuance by 12.0 million shares of common stock. As a result, 14,508,002 shares are authorized for issuance under the PIPP. As of September 30, 2022, all awards granted under the PIPP were in the form of restricted stock units to employees, directors, or consultants of the Company. As of September 30, 2022, there were 9,452,267 shares available for issuance under the PIPP. For restricted stock units granted prior to August 2020, a price per share was not determined upon the grant date. The number of shares of common stock of the Company to be issued upon vesting was calculated on the vesting date, which was either the second or third anniversary of the date of the grant, or the annual date the compensation committee determined the achievement of the corporate performance targets. Such unvested restricted stock unit awards were included in Other liabilities until each vesting date when the amount was transferred to Additional paid-in capital . As of September 30, 2022, there were no remaining restricted stock unit grants outstanding required to be accounted for as Other liabilities . Prior to each vesting date, the Company estimated the number of shares of common stock to be issued upon vesting using the closing share price of its common stock on the last day of each reporting period as quoted on the Nasdaq Capital Market. The following table summarizes the Company’s unvested share awards outstanding under the PIPP: Nine Months Ended Unvested at beginning of year (1) 2,210,911 Granted 3,007,069 Impact of fluctuations in share price (2) (515,198) Canceled/forfeited (282,500) Vested (1,141,980) Unvested end of period 3,278,302 (1) Amount includes liability-based awards for which the number of units awarded was not determined until the vesting date. The number of liability-based award units included in this amount are estimated using the market value of the Company’s common shares as of the end of each reporting period . (2) Amount represents difference between liability-based awards estimated as of the end of the previous reporting period and the number of shares of common stock issued upon vesting. During the nine months ended September 30, 2022 and 2021, the Company reclassified $0.7 million and $0.8 million from Other liabilities, current to Additional paid-in capital for restricted stock units that vested.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s anticipated annual tax rate is impacted primarily by the amount of taxable income associated with each jurisdiction in which its income is subject to income tax, permanent differences between the financial statement carrying amounts, and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Section 382 of the Internal Revenue Code (“IRC”) imposes limitations on the use of U.S. federal net operating losses (“NOLs”) upon a more than 50% change in ownership in the Company (as defined in the IRC) within a three-year period. In connection with its at-the-market equity offering, the Company underwent a Section 382 ownership change on March 25, 2022. As a result, utilization of the Company’s net operating losses and certain unrealized losses are limited on an annual basis. If the Section 382 annual limitation amount is not fully utilized in a particular tax year, then the unused portion from that tax year is added to the Section 382 annual limitation in subsequent years. The Company’s annual limitation under Section 382 is approximately $1.3 million. The Company incurred no net income tax expense or benefit for the three and nine months ended September 30, 2022. During the three and nine months ended September 30, 2021, the Company recorded an income tax benefit of $0.1 million for discrete items related estimated tax payments submitted prior to the Recapitalization Transaction. The effective tax rate for the three and nine months ended September 30, 2022 was nil. The effective tax rate for the three and nine months ended September 30, 2021, and 2020, was 0.2% and 0.0%, respectively. The effective tax rate differed from the statutory rate during each period primarily due to changes in the valuation allowance established to offset net deferred tax assets.

Due to the Company’s net loss during the three and nine months ended September 30, 2022 and 2021, respectively, there was no dilutive effect of common stock equivalents because the effects of such would have been anti-dilutive. The following table summarizes the shares excluded from the weighted average number of shares of common stock outstanding, as the impact would be anti-dilutive (in thousands): September 30, 2022 2021 Warrants (1) 94,296 56,595 Restricted stock units 3,278 1,190 Total 97,574 57,785 (1) See Note 12 - Warrant Liabilities for adjustments to the Seller Warrants for common stock issuable upon exercise.

Fair Value Measurements	Fair Value Measurements Recurring fair value measurements The following table sets forth by level within the fair value hierarchy, the Company’s liabilities measured at fair value on a recurring basis (dollars in thousands). Hierarchy September 30, December 31, Warrant liabilities 5-Year Private Warrants 2 1,128 664 Seller Warrants 2 5 5 Total $ 1,133 $ 669 5-Year Private Warrants The 5-Year Private Warrants are valued using a Black-Scholes model that requires a variety of inputs including the Company's stock price, the strike price of the 5-Year Private Warrants, the risk-free rate, and the implied volatility. As the terms of the 5-Year Private Warrants are identical to the terms of the 5-Year Public Warrants except that the 5-Year Private Warrants, while held by certain holders or their permitted transferees, are precluded from mandatory redemption and are entitled to be exercise on a “cashless basis” at the holder’s election, the implied volatility used in the Black-Scholes model is calculated using a Monte-Carlo model of the 5-Year Public Warrants that factors in the restrictive redemption and cashless exercise features of the 5-Year Private Warrants. The Company updates the fair value calculation on at least a quarterly basis, or more frequently if changes in circumstances and assumptions indicate a change from the existing carrying value. Seller Warrants The Seller Warrant Agreement contains certain terms and features to reduce the exercise price and increase the number of shares of common stock each warrant is exercisable into. As a result, Seller Warrants were considered derivative financial instruments and carried at fair value. The fair value of Seller Warrants was computed by an independent third-party consultant (and validated by the Company) using a Monte Carlo simulation-based model that requires a variety of inputs, including contractual terms, market prices, exercise prices, equity volatility and discount rates. The Company updated the fair value calculation on at least an annual basis, or more frequently if changes in circumstances and assumptions indicate a change from the existing carrying value. As of October 22, 2022 the Seller Warrants expired pursuant to their terms and are no longer exercisable or outstanding. Items disclosed at fair value Debt, net

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, the Company is involved in various legal actions related to its business, some of which have been class action lawsuits. Management does not believe, based on currently available information, that contingencies related to any pending or threatened legal matter will have a material adverse effect on the Company’s condensed consolidated financial statements, although a contingency could be material to the Company’s results of operations or cash flows for a particular period depending on the results of operations and cash flows for such period. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. The Company has deductible-based insurance policies for certain losses related to general liability, workers’ compensation and automobile coverage. The Company records accruals for contingencies related to its insurance policies when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted periodically as assessments change or additional information becomes available. Insurance losses for claims filed and claims incurred but not reported are accrued based upon estimates of the aggregate liability for uninsured claims using historical loss development factors and actuarial assumptions followed in the insurance industry. Financial commitments and contingencies not recorded in the financial statements As of September 30, 2022 and December 31, 2021, the Company’s off-balance sheet arrangements consisted of a net smelter royalty arrangement and a net profit royalty arrangement. Crofoot Royalty A portion of the Hycroft Mine is subject to a mining lease that requires a 4% net profit royalty be paid to the owner of certain patented and unpatented mining claims (“Crofoot Royalty”). The mining lease also requires an annual advance payment of $120,000 every year mining occurs on the leased claims. All advance annual payments are credited against the future payments due under the 4% net profit royalty. An additional payment of $120,000 is required for each year total tons mined on the leased claims exceeds 5.0 million tons. As the Company ceased mining operations in November 2021, the Company was not required to pay the annual advance payment of $120,000 in 2022. The total payments due under the mining lease are capped at $7.6 million, of which the Company has paid or accrued $3.0 million and included $0.6 million in Other assets in the Condensed Consolidated Balance Sheets as of September 30, 2022. Net smelter royalty Pursuant to the Sprott Royalty Agreement in which the Company received cash consideration in the amount of $30.0 million, the Company granted a perpetual royalty equal to 1.5% of the Net Smelter Returns from its Hycroft Mine, payable monthly. Net Smelter Returns for any given month are calculated as Monthly Production multiplied by the Monthly Average Gold Price and the Monthly Average Silver Price, minus Allowable Deductions, as such terms are defined in the Sprott Royalty Agreement. The Company is required to remit royalty payments to the payee free and clear and without any present or future deduction, withholding, charge or levy on account of taxes, except Excluded Taxes as such term is defined in the Sprott Royalty Agreement. At both September 30, 2022 and December 31, 2021, the estimated net present value of the Company’s net smelter royalty was $146.7 million. The net present value of the Company’s net smelter royalty was modeled using the following level 3 inputs: (i) market consensus inputs for future gold and silver prices; (ii) a precious metals industry consensus discount rate of 5.0%; and (iii) estimates of the Hycroft Mine’s life-of-mine gold and silver production volumes and timing.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation These condensed consolidated interim financial statements of the Company have been prepared, without audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, these condensed consolidated financial statements do not include all information and footnotes necessary for a comprehensive presentation of financial position, results of operations, or cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2021. The Company continues to follow the accounting policies set forth in those audited consolidated financial statements with updates discussed below. In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements include all adjustments that are necessary for a fair presentation of the Company’s interim financial position, operating results, and cash flows for the periods presented.
Liquidity	Liquidity As of September 30, 2022, the Company had available unrestricted cash on hand of $153.4 million and net working capital of $155.2 million which is expected to provide it with the necessary liquidity to fund its operating and investing requirements and future obligations as they become due within the next twelve months from the date of this filing. While the Company has continued to process gold and silver ore on the leach pads and in the drain down solutions to partially offset the cash that is projected to be used in its operations and investing activities, the Company does not expect to generate net positive cash from operations for the foreseeable future. Accordingly, the Company will be dependent on its unrestricted cash and other sources of cash to fund its business. As discussed in Note 14 - Stockholders’ Equity, the Company raised gross proceeds of $194.4 million in March 2022 through the following equity financings: • On March 14, 2022, the Company entered into subscription agreements with American Multi-Cinema, Inc. (“AMC”) and 2176423 Ontario Limited, an entity affiliated with Eric Sprott, pursuant to which the Company agreed to sell an aggregate of 46,816,480 units at a purchase price of $1.193 per unit for total gross proceeds, before deduction of fees and expenses, of $55.9 million. • On March 15, 2022, the Company implemented an ATM pursuant to which the Company registered the offer and sale from time to time of its common stock having an aggregate offering price of up to $500.0 million of gross proceeds. Under the ATM Program, which was completed on March 25, 2022, the Company sold 89,553,584 shares of common stock for gross proceeds, before commissions and offering expenses, of $138.6 million. Also, as discussed in Note 10 - Debt, Net , as a result of the equity financings above, the Company reached an agreement with Sprott Private Resource Lending II (Collector), LP (the “Lender”) with respect to the Credit Agreement among Hycroft Mining Holding Corporation, as borrower, Autar Gold Corporation, MUDS, MUDS Holdco Inc., Allied VGH LLC, Hycroft Resources and Development, LLC, Sprott Private Resource Lending II (Collector) Inc., and Sprott Resources Lending Corp. (“Sprott Credit Agreement”), which required the Company to prepay principal under the facility in the amount of $10.0 million following the Company’s receipt of the $55.9 million cash proceeds discussed above. The Company also made an additional prepayment of $13.9 million on March 30, 2022. In addition to the above equity financings, the Company will continue to evaluate alternatives to raise additional capital necessary to fund the future exploration and development of the Hycroft Mine and will continue to explore other strategic initiatives to enhance stockholder value. Historically, the Company has been dependent on various forms of debt and equity financing to fund its business. While the Company has been successful in the past raising funds through equity and debt financings, no assurance can be given that additional financing will be available to it in amounts sufficient to meet the Company’s needs or on terms acceptable to the Company. In the event that funds are not available, the Company may be required to materially change its business plans.
Use of estimates	Use of estimates The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in these condensed consolidated financial statements and accompanying notes. The more significant areas requiring the use of management estimates and assumptions relate to: recoverable gold and silver ounces on leach pads and in-process inventories; timing of near-term ounce production and related sales; the useful lives of long-lived assets; estimates of mineral resources; estimates of life-of-mine production timing, volumes, costs and prices; future mining and current and future processing plans; environmental reclamation and closure costs and timing; deferred taxes and related valuation allowances; estimates of the fair value of liability classified warrants, and estimates of fair value for asset impairments and financial instruments. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable at the time the estimate is made. Actual results may differ from amounts estimated in these condensed consolidated financial statements, and such differences could be material. Accordingly, amounts presented in these condensed consolidated financial statements are not indicative of results that may be expected for future periods.
Cash and cash equivalents	Cash and cash equivalents During the third quarter of 2022, the Company invested in the AAAm rated US Government Money Market Funds that are readily convertible to cash and, as such, the Company has included them in Cash and cash equivalents . As of December 31, 2021, cash consisted of cash balances. The Company has not experienced any losses on cash balances and believes that no significant risk of loss exists with respect to its cash.
Recently adopted accounting pronouncements	Recently adopted accounting pronouncements In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU 2020-06 simplifies guidance on accounting for convertible instruments and contracts in an entity’s own equity including calculating diluted earnings per share. For emerging growth companies, the new guidance is effective for annual periods beginning after December 15, 2022. The Company early adopted ASU 2020-06 as of January 1, 2022, with no material impact on its condensed consolidated financial statements or the related disclosures. In December of 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), as part of its overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements.

ASU 2021-04 clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options ( e.g., warrants) that remain equity classified after modification or exchange. ASU 2021-04 provides guidance that will clarify whether an issuer should account for a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange as (i) an adjustment to equity and, if so, the related earnings per share effects, if any, or (ii) an expense and, if so, the manner and pattern of recognition. For emerging growth companies, the new guidance was effective for annual periods beginning after December 15, 2021 and the Company adopted ASU 2021-04 as of January 1, 2022, with no material impact on its condensed consolidated financial statements or the related disclosures.
