Basis of Presentation
Basis of Presentation	1. Basis of Presentation Fortitude Gold Corporation (the “Company,” “FGC,” or “Fortitude”) was organized under the laws of the State of Colorado on August 11, 2020. On August 18, 2020, Gold Resource Corporation (“GRC” or “Parent”) transferred all of the 10,000 issued and outstanding common stock shares of its wholly-owned subsidiary GRC Nevada Inc. (“GRCN”) to Fortitude in exchange for 21,211,208 shares of Fortitude’s common stock. With the share transfer, GRCN became a wholly-owned subsidiary of Fortitude and Fortitude became a wholly-owned subsidiary of GRC. The assets and liabilities were recorded at historical cost as the entities were under common control. On December 31, 2020, GRC completed the spin-off of FGC (“Spin-Off”), which separated FGC’s business, activities, and operations into a separate, public company. The Spin-Off was effected by the distribution of all of the outstanding shares of FGC common stock to GRC’s shareholders. GRC’s shareholders received one share of FGC common stock for every 3.5 shares of GRC’s common stock held as of December 28, 2020. FGC is a mining company which pursues gold and silver projects that are expected to have both low operating costs and high returns on capital. These interim Condensed Consolidated Financial Statements (“interim financial statements”) are unaudited and have been prepared in accordance with the rules of the Securities and Exchange Commission for interim statements. The condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020, the condensed consolidated statements of operations and shareholders’ equity for the three and nine months ended September 30, 2021, and the condensed consolidated statement of cash flows for the nine months ended September 30, 2021 include the accounts of the Company, its subsidiaries GRCN, Walker Lane Minerals Corp. (“Walker Lane”), County Line Holdings, Inc., and County Line Minerals Corp. The condensed consolidated statements of operations and shareholder’s equity for the three and nine months ended September 30, 2020, and the condensed consolidated statement of cash flows for the nine months ended September 30, 2020 include the accounts of GRCN, WLMC, County Line Holdings, Inc., and County Line Minerals Corp. and have been derived from the accounting records of GRC and should be read with the accompanying notes thereto. All intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures required by United States Generally Accepted Accounting Principles (“U.S. GAAP”) have been condensed or omitted as permitted by such rules, although the Company believes that the disclosures included are adequate to make the information presented not misleading. The interim financial statements included herein are expressed in United States dollars. In the opinion of management, all adjustments (all of which are of a normal recurring nature) and disclosures necessary for a fair presentation of these interim financial statements have been included. The results reported in these interim financial statements are not necessarily indicative of the results that may be reported for the entire year. These interim financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in the Company’s annual report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements. Unless otherwise noted, there have been no material changes to the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s annual report on Form 10-K. The condensed consolidated statements of operations and shareholder’s equity for the three and nine months ended September 30, 2020 and the condensed consolidated statement of cash flows for the nine months ended September 30, 2020 have been prepared on a “carve-out” basis. The accompanying statements include allocations of certain expenses for human resources, accounting, and other services, plus share-based compensation allocated from GRC. The expense allocations have been determined on basis that the Company and GRC consider to be reasonable reflections of the utilization of services or the benefits provided. In addition, the assets and liabilities include only those assigned to the carve-out entities. The allocations and related estimates and assumptions are described more fully in Note 2

Related Party Transactions
Related Party Transactions	2. Related Party Transactions Effective December 31, 2020, in connection with the Spin-Off, the Company entered into a Management Services Agreement (“MSA” or “Agreement”) with GRC that governs the relationship of the parties following the Spin-Off. The MSA provides that the Company receives services from GRC and its subsidiaries to assist in the transition of the Company as a separate company including, managerial and technical supervision, advisory and consultation with respect to mining operations, exploration, environmental, safety and sustainability matters. The Company also receives certain administrative services related to information technology, accounting and financial advisory services, legal and compliance support and investor relation and shareholder communication services. The agreed upon charges for services rendered are based on market rates that align with the rates that an unaffiliated service provider would charge for similar services. The MSA’s initial term was to expire on December 31, 2021, would automatically renew annually and may be cancelled upon 30 days written notice by one party to the other during the term. On April 21, 2021, GRC provided the Company 30 days written notice to cancel the MSA effective May 21, 2021. During the nine months ended September 30, 2021, the Company recognized $0.4 million of expense related to the MSA. ​ Prior to the Spin-Off, GRC provided human resources, information technology, accounting, legal, technical, and other services to the Company. The Company obtained its business insurance under GRC. The accompanying condensed consolidated statements of operations and shareholder’s equity for the three and nine months ended September 30, 2020 and condensed consolidated statement of cash flows for the nine months ended September 30, 2020 include allocations of all of these expenses. The allocation method calculates the appropriate share of overhead cost to the Company by using time spent by GRC employees. The Company believes the allocation methodology used is reasonable, has been consistently applied, and results in an appropriate allocation of costs incurred. However, these allocations may not be indicative of the cost had the Company been a stand-alone entity or of future services. GRC allocated $0.6 million and $1.8 million for the three and nine months ended September 30, 2020, respectively. These costs were treated as capital contributions from GRC in the accompanying 2020 financial statements. In addition, the Company received cash contributions from GRC to help fund its operations and mine development, which are not expected to be repaid and are treated as capital contributions. For the three and nine months ended September 30, 2020, the Company received total capital contributions from GRC of $0.9 million and $10.7 million, respectively, inclusive of allocated costs described above.

Income Taxes
Income Taxes	5. Income Taxes The Company accounts for income taxes in accordance with the provisions of ASC 740, “Income Taxes” (“ASC 740”), on a tax jurisdictional basis. The Company files a consolidated U.S. income tax return and at the federal level its income and losses are taxed at 21%. In addition, a 5% Net Proceeds of Minerals tax applies to the Company’s operations in Nevada, and such tax is recorded as an income tax. The Company recorded income and mining tax expense of $1.5 million and $0.2 million for the three months ended September 30, 2021 and 2020, respectively. The Company recorded income and mining tax expense of $5.1 million and $0.7 million for the nine months ended September 30, 2021 and 2020, respectively. In accordance with ASC 740, the interim provision for taxes was calculated by using the annual effective tax rate. This rate is applied to the year-to-date income before income and mining taxes to determine the income tax expense for the period. The Company evaluates the evidence available to determine whether a valuation allowance is required on the deferred tax assets. The Company determined that its deferred tax assets were “more likely than not” to be realized as of September 30, 2021 and December 31, 2020, thus no valuation allowance was determined to be necessary. ​ As of September 30, 2021, the Company believes that is has no liability for uncertain tax positions.

Leases
Leases	12. Leases Operating Leases Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases as incurred over the lease term. For leases beginning in 2019 and later, the Company accounts for lease components (e.g., fixed payments including rent, real estate taxes and insurance costs) separately from the non-lease components (e.g., common-area maintenance costs). The depreciable life of assets is limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The weighted average remaining lease term for the Company’s operating leases as of September 30, 2021 is 0.08 years. The discount rate implicit within the Company’s leases is generally not determinable and therefore the Company determines the discount rate based on its incremental borrowing rate. The incremental borrowing rate for the Company’s leases is determined based on the lease term adjusted for impacts of collateral. The weighted average discount rate used to measure the Company’s operating lease liabilities as of September 30, 2021 was 4.48%. There are no material residual value guarantees and no restrictions or covenants imposed by the Company’s leases. The Company has an embedded lease in its Contract Mining Agreement. The Company’s lease payments for its mining equipment embedded lease are determined by tonnage hauled.

Net Income per Common Share	14. Net Income per Common Share Basic earnings per common share is calculated based on the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated based on the assumption that stock options and other dilutive securities outstanding, which have an exercise price less than the average market price of the Company’s common shares during the period, would have been exercised on the later of the beginning of the period or the date granted and that the funds obtained from the exercise were used to purchase common shares at the average market price during the period. The effect of the Company’s dilutive securities is calculated using the treasury stock method and only those instruments that result in a reduction in net income per common share are included in the calculation. Options to purchase ​ Basic and diluted net income per common share is calculated as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Nine months ended ​ ​ ​ September 30, ​ September 30, ​ ​ 2021 2020 ​ 2021 2020 ​ Net income (in thousands) ​ $ 4,646 ​ $ 3,477 ​ $ 15,381 ​ $ 411 ​ Basic weighted average shares of common stock outstanding ​ ​ 23,961,208 ​ ​ 10,000 ​ ​ 23,846,686 ​ ​ 10,000 ​ Diluted effect of share-based awards ​ ​ 250,398 ​ ​ — ​ ​ 231,540 ​ ​ — ​ Diluted weighted average common shares outstanding ​ ​ 24,211,606 ​ ​ 10,000 ​ ​ 24,078,226 ​ ​ 10,000 ​ Net income per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic ​ $ 0.19 ​ $ 348 ​ $ 0.64 ​ $ 41 ​ Diluted ​ $ 0.19 ​ $ 348 ​ $ 0.64 ​ $ 41 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

Fair Value Measurement

Fair Value Measurement
Fair Value Measurement	15. Fair Value Measurement Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). As required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables set forth certain of the Company’s assets measured at fair value by level within the fair value hierarchy as of September 30, 2021 and December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Input Hierarchy Level ​ (in thousands) ​ Cash and cash equivalents ​ $ 44,337 ​ $ 27,774 ​ Level 1 Accounts receivable ​ 1,628 ​ 145 ​ Level 2 Loans payable ​ $ 153 ​ $ 782 ​ Level 2 ​ The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Cash and cash equivalents consist primarily of cash deposits and are valued at cost, which approximates fair value. Accounts receivable include amounts due to the Company for deliveries of doré sold to customers, which approximates fair value. Loans payable consist of obligations for equipment purchases financed on a long-term basis. Loans payable are recorded at amortized cost, which approximates fair value. See Note 10

Stock-Based Compensation
Stock-Based Compensation	16. Stock-Based Compensation The Fortitude Gold Corporation 2020 Equity Incentive Plan (the “Incentive Plan”) allows for the issuance of up to 5 million shares of common stock in the form of incentive and non-qualified stock options, stock appreciation rights, restricted stock units (“RSUs”), stock grants, and stock units. The Company utilizes this Incentive Plan to attract, retain and incentivize staff. ​ During the nine months ended September 30, 2021, in conjunction with its staffing process post Spin-Off, the Company issued 2,250,000 shares of its common stock to officers, directors, management and other key personnel. These shares immediately vested at a fair value ranging from $1.40 per share to $5.48 per share. No shares were issued during the three months ended September 30, 2021. ​ During the nine months ended September 30, 2021, the Company issued options to purchase 462,000 shares of its common stock to employees and key personnel other than its officers or directors. The options vest over a period of three years. The Company used the Black-Scholes option valuation model to value the options with the following assumptions: stock price of $1.40 to $5.48, expected term of 3.5 years, risk free rate of 0.26% to 0.53%, expected volatility of 73.56% to 74.67%, and an assumed dividend rate of 0% to 4.6%. No options to purchase common stock were issued during the three months ended September 30, 2021. ​ Stock-based compensation is included in general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. For the three and nine months ended September 30, 2021, the Company recorded $0.1 million and $3.4 million, respectively, of stock-based compensation. For the three and nine months ended September 30, 2020, the Company recognized stock-based compensation expenses allocated from GRC, as described in Note 2
