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. 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. 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.
