Organization, Consolidation and Presentation of Financial Statements [Abstract]
Company Overview	Company Overview Hycroft Mining Holding Corporation and its subsidiaries (collectively, “Hycroft”, the “Company”, “we”, “us”, “our”, “it”, or “HYMC”) is a U.S.-based gold and silver company that is focused on exploring and developing the Hycroft Mine in a safe, environmentally responsible, and cost-effective manner. The Hycroft Mine is located in the State of 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 operated the Hycroft Mine until November 2021, when it discontinued active mining operations 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 to further determine the most effective processing method for the sulfide ore. In March 2023, the Company, along with its third-party consultants, completed and filed the Hycroft Property Initial Assessment Technical Report Summary Humboldt and Pershing Counties, Nevada (“2023 Hycroft TRS”) that included a mineral resource estimate utilizing a pressure oxidation (“POX”) process for sulfide mineralization and heap leaching process for oxide and transition mineralization.The Company is focusing on exploration drilling and data analyses, completing technical studies, conducting trade-off studies and alternative analyses for determining the optimal process flow sheet for processing sulfide ores and recovering gold and silver, and maintaining the Hycroft Mine. Beginning in the fourth quarter of 2023, the Company again began accessing its at-the-market public offering program (“ATM Program”). During the three months ended March 31, 2024, the Company sold 517,688 shares of common stock for aggregate gross proceeds, before commissions and offering expenses, of $1.2 million. As of March 31, 2024 and December 31, 2023, there were $14.8 million and $360.3 million, respectively, gross sales price of common stock available for issuance under the ATM Program. The net proceeds from the ATM Program have been, and are expected to be, used for general corporate purposes, which may include the repayment, refinancing, redemption, or repurchase of existing indebtedness, exploration, working capital, or capital expenditures and other investments.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation These Unaudited Condensed Consolidated Financial Statements (“Financial Statements”) of the Company have been prepared 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 Financial Statements do not include all information and footnotes necessary for a comprehensive presentation of financial position, results of operations, or cash flows. These Financial Statements should be read in conjunction with the Company’s Audited Consolidated Financial Statements and the notes thereto (the “Notes”) as of and for the year ended December 31, 2023 (the “2023 Audited Financial Statements”), filed as a part of the Company’s annual report on Form 10-K filed with the SEC on March 14, 2024. The Company continues to follow the accounting policies set forth in the 2023 Audited Financial Statements, with updates discussed below. In the opinion of management, the accompanying 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. Use of estimates The preparation of the Financial Statements requires management to make estimates and assumptions that affect amounts reported in these Financial Statements and accompanying notes. The more significant areas requiring the use of management estimates and assumptions relate to the useful lives of long-lived assets; future mining and processing plans; environmental reclamation and closure costs and timing; and estimates of fair value for long-lived assets, Assets held for sale , and financial instruments. The Company bases its estimates on historical experience and other assumptions, including drilling and assay data that are believed to be reasonable at the time the estimate is made. Actual results may differ from amounts estimated in these Financial Statements, and such differences could be material. Accordingly, amounts presented in these Financial Statements may not be indicative of results that may be expected for future periods. New accounting pronouncements not yet adopted In March 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements. The amendments are considered to be codification improvements only and therefore are not expected to significantly affect current accounting practice. The guidance is to clarify guidance, simplify wording or structure of guidance, and other minor improvements. The new guidance is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact that adopting this update will have on its Financial Statements and related disclosures. Impairment of long-lived assets The Company’s long-lived assets consist of Note 5 – Plant and Equipment, Net. The Company routinely reviews and evaluates its long-lived assets for impairment to ensure there are no new events or changes in circumstances that would indicate that the related carrying amounts may not be recoverable. Events that may trigger a test for recoverability include, but are not limited to, significant adverse changes to projected Revenues, costs, or future expansion plans or changes to federal and state regulations (with which the Company must comply) that may adversely impact the Company’s current or future operations. An impairment is determined to exist if the total projected future cash flows on an undiscounted basis are less than the carrying amount of a long-lived asset group. An impairment loss is measured and recorded based on the excess carrying value of the impaired long-lived asset group over fair value. In estimating future cash flows, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of future cash flows from other asset groups. The Company’s estimates of future cash flows and estimates of fair value are based on numerous assumptions and are subject to significant risks and uncertainties. See Note 5 – Plant and Equipment, Net for additional information. During the three months ended March 31, 2024, the Company completed its evaluation and determined no impairment was necessary.

Warrant Liabilities	Warrant Liabilities 5-Year Private Warrants The Company’s outstanding warrant liabilities include 5-Year Private Warrants. The 5-Year Private Warrants cannot be redeemed and can be exercised on a cashless basis if the 5-Year Private Warrants are held by the initial purchasers or their permitted transferees. If the 5-Year Private Warrants are transferred to someone other than the initial purchasers or their permitted transferees, such warrants become redeemable by the Company under substantially the same terms as the 5-Year Public Warrants. Since the original issue of private warrants, 9,374,578 warrants have been transferred from 5-Year Private Warrants and become 5-Year Public Warrants. During the three months ended March 31, 2024 and 2023, transfers from 5-Year Private Warrants to 5-Year Public Warrants totaled Nil and 6,176,794, respectively.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity At-the-market offering On March 15, 2022, the Company implemented an ATM Program by entering into an At Market Issuance Sales Agreement (“Sales Agreement”) with B. Riley Securities, Inc. (the “Agent”). Under the terms of the Sales Agreement, the Company may from time to time 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. Shares of common stock sold under the Sales Agreement were issued pursuant to the Company’s shelf registration statement on Form S-3 (No. 333-257567) that the SEC declared effective on July 13, 2021, including the prospectus, dated July 13, 2021, and the prospectus supplement, dated March 15, 2022. The Company 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, and approximately $361.4 million of shares of common stock remain available for future issuance under the Sales Agreement. Net proceeds, after deducting commissions and fees of $5.0 million were $133.5 million. On June 2, 2023, the Company filed a prospectus supplement reactivating the ATM Program and updating the amount of shares that the Company may sell through the ATM Program to an aggregate offering price of up to $361.4 million. On November 17, 2023, the Company again began accessing the ATM Program, and as of December 31, 2023, sold an additional 523,328 shares of common stock for aggregate gross proceeds, before commissions and offering expenses, of $1.1 million. On March 19, 2024, the Company filed a prospectus supplement subject to Instruction I.B.6. to Form S-3, which is referred to as the baby shelf rule. Pursuant to the baby shelf rule, as long as the Company’s public float is less than $75.0 million, it may not sell more than the equivalent of one-third of its public float during any 12 consecutive months. The prospectus supplement updated the remaining amount of shares that the Company may sell through the ATM Program to an aggregate offering price of up to $15.3 million. During the three months ended March 31, 2024, the Company sold 517,688 shares of common stock for aggregate gross proceeds, before commissions and offering expenses, of $1.2 million. As of March 31, 2024 and December 31, 2023, there were $14.8 million and $360.3 million, respectively, gross sales price of common stock available for issuance under the ATM Program. The net proceeds from the ATM Program have been, and are expected to be used for general corporate purposes, which may include the repayment, refinancing, redemption, or repurchase of existing indebtedness, exploration, working capital, or capital expenditures and other investments. On April 11, 2024, the Company’s public float exceeded the $75.0 million baby shelf threshold, and thus, the Company is no longer subject to its limitations.

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 and 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. The Company incurred Nil net income tax expense or benefit for the three months ended March 31, 2024 and 2023. The effective tax rate for the three months ended March 31, 2024 and 2023 was Nil and Nil, 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.

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 (in thousands). Hierarchy March 31, December 31, 5-Year Private Warrants 2 $ 21 $ 26 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. 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 exercised on a “cashless basis” at the holder’s election. The implied volatility used in the Black-Scholes model is calculated using a Generalized AutoRegressive Conditional Heteroskedasticity 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. Items disclosed at fair value The Sprott Credit Agreement and the Subordinated Notes are privately held and, as such, there is no public market or trading information available for such debt instruments. As of March 31, 2024 and December 31, 2023, the fair value of the Company’s debt instruments was $101.7 million and $149.2 million, respectively, compared to the carrying value of $116.8 million and $144.9 million as of March 31, 2024 and December 31, 2023, respectively. The fair value of the principal of the Company’s debt instruments, including capitalized interest, was estimated using a market approach in which pricing information for publicly traded, non-convertible debt instruments with speculative ratings was analyzed to derive a mean trading multiple to apply to the March 31, 2024 balances.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal proceedings From time to time the Company may be involved in various legal actions related to our business, some of which are class action lawsuits. The Company 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 Financial Statements, although a contingency could be material to the Company’s results of operations or cash flows for a particular period depending on its results of operations and cash flows for such period. Regardless of the outcome, litigation can have a material adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. The Company expenses legal fees and other costs associated with legal proceedings as incurred. The Company assessed, in conjunction with its legal counsel, the need to record a liability related to the Complaints and determined that a loss was not probable nor reasonably estimable. Litigation accruals are recorded when, and if, it is determined that a loss related matter is both probable and reasonably estimable. Material loss contingencies that are reasonably possible of occurrence, if any, are subject to disclosure. No losses have been recorded during the three months ended March 31, 2024 and 2023 with respect to litigation or loss contingencies. Insurance The Company has deductible-based insurance policies for certain losses related to general liability, workers’ compensation, automobile coverage, and directors and officers. 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 March 31, 2024 and December 31, 2023, 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 payment of 4% net profit royalty to the previous 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 the 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 2024, 2023 or 2022. The total payments due under the mining lease are capped at $7.6 million, of which the Company has paid $3.3 million, including $0.6 million of advanced annual payments in Prepaids in the Unaudited Condensed Consolidated Balance Sheets as of March 31, 2024 and December 31, 2023. Sprott Royalty Pursuant to the Royalty Agreement with Sprott Private Resource Lending II (CO) Inc. 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 the Hycroft Mine, payable monthly (“Sprott Royalty Agreement”). The royalty is accounted for as a deferred gain liability. 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 th e 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 March 31, 2024 and December 31, 2023, the estimated net present value of the Sprott Royalty Agreement was $146.7 million. The net present value of the Sprott Royalty Agreement 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 Unaudited Condensed Consolidated Financial Statements (“Financial Statements”) of the Company have been prepared 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 Financial Statements do not include all information and footnotes necessary for a comprehensive presentation of financial position, results of operations, or cash flows. These Financial Statements should be read in conjunction with the Company’s Audited Consolidated Financial Statements and the notes thereto (the “Notes”) as of and for the year ended December 31, 2023 (the “2023 Audited Financial Statements”), filed as a part of the Company’s annual report on Form 10-K filed with the SEC on March 14, 2024. The Company continues to follow the accounting policies set forth in the 2023 Audited Financial Statements, with updates discussed below. In the opinion of management, the accompanying 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.
Use of estimates	Use of estimates The preparation of the Financial Statements requires management to make estimates and assumptions that affect amounts reported in these Financial Statements and accompanying notes. The more significant areas requiring the use of management estimates and assumptions relate to the useful lives of long-lived assets; future mining and processing plans; environmental reclamation and closure costs and timing; and estimates of fair value for long-lived assets, Assets held for sale , and financial instruments. The Company bases its estimates on historical experience and other assumptions, including drilling and assay data that are believed to be reasonable at the time the estimate is made. Actual results may differ from amounts estimated in these Financial Statements, and such differences could be material. Accordingly, amounts presented in these Financial Statements may not be indicative of results that may be expected for future periods.
New accounting pronouncements not yet adopted	New accounting pronouncements not yet adopted In March 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements. The amendments are considered to be codification improvements only and therefore are not expected to significantly affect current accounting practice. The guidance is to clarify guidance, simplify wording or structure of guidance, and other minor improvements. The new guidance is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact that adopting this update will have on its Financial Statements and related disclosures.
Impairment of long-lived tangible assets	Impairment of long-lived assets The Company’s long-lived assets consist of Note 5 – Plant and Equipment, Net. The Company routinely reviews and evaluates its long-lived assets for impairment to ensure there are no new events or changes in circumstances that would indicate that the related carrying amounts may not be recoverable. Events that may trigger a test for recoverability include, but are not limited to, significant adverse changes to projected Revenues, costs, or future expansion plans or changes to federal and state regulations (with which the Company must comply) that may adversely impact the Company’s current or future operations. An impairment is determined to exist if the total projected future cash flows on an undiscounted basis are less than the carrying amount of a long-lived asset group. An impairment loss is measured and recorded based on the excess carrying value of the impaired long-lived asset group over fair value. In estimating future cash flows, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of future cash flows from other asset groups. The Company’s estimates of future cash flows and estimates of fair value are based on numerous assumptions and are subject to significant risks and uncertainties. See Note 5 – Plant and Equipment, Net for additional information. During the three months ended March 31, 2024, the Company completed its evaluation and determined no impairment was necessary.
