Basis of Preparation of Financial Statements and Nature of Operations
Basis of Preparation of Financial Statements and Nature of Operations	1. Basis of Preparation of Financial Statements and Nature of Operations Golden Minerals Company (the “Company”), a Delaware corporation, has prepared these unaudited interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). The interim condensed consolidated financial statements do not include all disclosures required by GAAP for annual financial statements, but in the opinion of management, include all adjustments necessary for a fair presentation. Certain prior period amounts may have been reclassified to conform to current classifications. Interim results are not necessarily indicative of results for a full year; accordingly, these interim financial statements should be read in conjunction with the annual financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and filed with the SEC on March 23, 2022. The Company is a mining company, holding a 100% interest in the Rodeo property in Durango State, Mexico (the “Rodeo Property”), a 100% interest in the Velardeña and Chicago precious metals mining properties and associated oxide and sulfide processing plants in the state of Durango, Mexico (the “Velardeña Properties”), a 100% interest in the El Quevar advanced exploration silver property in the province of Salta, Argentina, which is subject to the terms of the April 9, 2020 earn-in agreement (the “Earn-in Agreement”) pursuant to which Barrick Gold Corporation (“Barrick”) has the option to earn a 70% interest in the El Quevar project (see Note 8), and a diversified portfolio of precious metals and other mineral exploration properties located primarily in or near historical precious metals producing regions of Mexico, Argentina and Nevada. The Rodeo Property, Velardeña Properties and the El Quevar advanced exploration property are the Company’s only material properties. The Company is primarily focused on mining operations at the Rodeo Property as well as further studies of a restart plan for the Velardeña mine, including use of bio-oxidation to improve the payable gold recovery. The Company is also focused on (i) advancing the El Quevar exploration property in Argentina through the Earn-in Agreement with Barrick and (ii) continuing to evaluate and search for mining opportunities in North America (including Mexico) with near-term prospects of mining, and particularly for properties within reasonable haulage distances of our processing plants at the Velardeña Properties. The Company is also reviewing strategic opportunities, focusing primarily on development or operating properties in North America, including Mexico. The Company began mining activities at the Rodeo Property during December 2020 and began processing mined material from Rodeo at the Velardeña plant in January 2021. The employees at the Rodeo and Velardeña Properties, in addition to those who operate the plant that processes the Rodeo mined material, include an operations group, an administrative group and an exploration group to continue to advance the Company’s plans in Mexico and to provide oversight for corporate compliance activities as well as maintaining and safeguarding the longer-term value of the Velardeña Properties assets. The Company is considered an exploration stage issuer under the criteria set forth by the SEC under Regulation SK subpart 1300 (“S-K 1300”) as the Company has not yet demonstrated the existence of mineral reserves at any of the Company’s properties. As a result, and in accordance with GAAP for exploration stage companies, all expenditures for exploration and evaluation of the Company’s properties are expensed as incurred. As such, the Company’s financial statements may not be comparable to the financial statements of mining companies that do have proven and probable mineral reserves. Such companies would typically capitalize certain development costs including infrastructure development and mining activities to access the ore. The capitalized costs would be amortized on a units-of-production basis as reserves are mined. The amortized costs are typically allocated to inventory and eventually to cost of sales as the inventories are sold. As the Company does not have proven and probable mineral reserves, substantially all expenditures at the Company’s Rodeo property and the Velardeña Properties for mine construction activity, as well as operating costs associated with the mill facilities, and for items that do not have a readily identifiable market value apart from the mineralized material, have been expensed as incurred. Such costs are charged to cost of metals sold or project expense during the period depending on the nature of the costs. Certain of the costs may be reflected in inventories prior to the sale of the product. The Company cannot be certain that any deposits at any of its properties will ever be confirmed or converted into S-K 1300 compliant “reserves”.

Correction of Immaterial Error - Income Taxes
Correction of Immaterial Error	3. Correction of Immaterial Error In the first quarter 2022, the Company became aware that at December 31, 2021, it had failed to properly record a royalty tax payable in Mexico related to its Rodeo operations. The effect of correcting this error was to reduce beginning retained earnings by $93,000 at January 1, 2022, as reflected in the accompanying Condensed Consolidated Statements of Changes in Equity. The Company evaluated the materiality of the error described above from a qualitative and quantitative perspective. Based on such evaluation, the Company concluded that while the accumulation of the error was significant to the three months ended March 31, 2022, the correction would not be material to results of operations for the period ended December 31, 2021, nor did it have an effect on the trend of financial results, taking into account the requirements of the SEC Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”). Accordingly, the error was corrected for the December 31, 2021, Condensed Consolidated Balance Sheets included in this Form 10-Q.

Cash and Cash Equivalents and Short-Term Investments	4. Cash and Cash Equivalents and Short-term Investments Of the $9.5 million reported as “Cash and cash equivalents” on the Condensed Consolidated Balance Sheets at June 30, 2022, the Company had approximately $153,000 that was unavailable for use due to a court order freezing the bank accounts of one of the Company’s subsidiaries in Mexico related to a lawsuit, as further described in Note 19. The restrictions imposed on the subsidiary’s bank accounts do not impact the Company’s ability to operate the Rodeo mine, which is held through a different Mexico subsidiary, or to continue with the Company’s evaluation plans for a potential Velardeña mine restart or move forward with any of the Company’s other exploration programs in Mexico. The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Short-term investments include investments with maturities greater than three months, but not exceeding 12 months, or highly liquid investments with maturities greater than 12 months that the Company intends to liquidate during the next 12 months for working capital needs. The following tables summarize the Company's short-term investments at June 30, 2022 and December 31, 2021: Estimated Carrying June 30, 2022 Cost Fair Value Value (in Investments: Short-term: Trading securities $ 59 $ 53 $ 53 Total trading securities 59 53 53 Total short term $ 59 $ 53 $ 53 December 31, 2021 Investments: Short-term: Trading securities $ 59 $ 67 $ 67 Total trading securities 59 67 67 Total short term $ 59 $ 67 $ 67 The short-term investments at June 30, 2022 and at December 31, 2021, consist of 1,000,000 common shares of Fabled Silver Gold Corp. (“Fabled”), and 200,000 common shares of Fabled Copper Corp. Fabled is a junior mining company that entered into an option agreement with the Company to acquire the Company’s option to earn a 100% interest in the Santa Maria mining claims located in Chihuahua, Mexico (see Note 8). The common shares were issued to the Company as partial consideration per the terms of the option agreement. The Fabled Copper Corp. shares were received in a spin-off of assets from Fabled that occurred on December 21, 2021, to which all existing shareholders of Fabled were entitled. Credit Risk The Company invests substantially all of its excess cash with high credit-quality financial institutions or in U.S. government or debt securities. Credit risk is the risk that a third party might fail to fulfill its performance obligations under the terms of a financial instrument. For cash and equivalents and investments, credit risk represents the carrying amount on the balance sheet. The Company mitigates credit risk for cash and equivalents and investments by placing its funds and investments with high credit-quality financial institutions, limiting the amount of exposure to each of the financial institutions, monitoring the financial condition of the financial institutions and investing only in government and corporate securities rated “investment grade” or better. The Company invests with financial institutions that maintain a net worth of not less than $1 billion and are members in good standing with the Securities Investor Protection Corporation.

Asset Retirement Obligation and Reclamation Liabilities
Asset Retirement and Reclamation Liabilities	12. Asset Retirement Obligation and Reclamation Liabilities The Company retained the services of a mining engineering firm to prepare a detailed closure plan for the Velardeña Properties. The plan was completed during the second quarter 2012 and indicated that the Company had an ARO and offsetting ARC of approximately $1.9 million at that time. In the fourth quarter of 2021, due to the current operating success at Rodeo and the potential of a restart of operations at the Velardeña mine based on recent technical studies and an updated PEA that would further delay the start of any reclamation activity, the Company retained the services of an environmental consultant to review the closure plan to determine the appropriateness of the scope and cost estimates used in the calculation of the ARO. The consultant confirmed the adequacy of the scope of the closure plan and provided certain adjustments to cost estimates. In addition, the timing for the incurrence of reclamation activity was extended approximately 7 years to take into account the likelihood of a restart of operations at the Velardeña mine that would further delay the start of any reclamation activity. The Company will continue to accrue additional estimated ARO amounts based on an asset retirement plan as activities requiring future reclamation and remediation occur. During the first six months of 2022, the Company recognized approximately $140,000 of accretion expense. The following table summarizes activity in the Velardeña Properties ARO: Six Months Ended June 30, 2022 2021 (in thousands) Beginning balance $ 3,561 $ 3,156 Changes in estimates, and other 30 (86) Accretion expense 140 131 Ending balance $ 3,731 $ 3,201 The change in estimates of the ARO recorded during 2021 is primarily the result of changes in assumptions related to inflation factors used in the determination of future cash flows. The asset retirement obligation and reclamation liability set forth on the accompanying Condensed Consolidated Balance Sheets at June 30, 2022 and December 31, 2021 also includes a nominal amount of reclamation liability related to activities at the El Quevar project in Argentina. Environmental costs at the Rodeo Property will be expensed as incurred. There were no environmental costs incurred at the Rodeo Property for the six months ended June 30, 2022 or June 30, 2021.

Fair Value Measurements
Fair Value Measurements	13. Fair Value Measurements Financial assets and liabilities and nonfinancial assets and liabilities are measured at fair value under a framework of a fair value hierarchy which prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to quoted prices (unadjusted) in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy per ASC 820 are as follows: Level 1 Level 2 Level 3 The following table summarizes the Company’s financial assets and liabilities at fair value on a recurring basis at June 30, 2022 and December 31, 2021, by respective level of the fair value hierarchy: Level 1 Level 2 Level 3 Total (in thousands) At June 30, 2022 Assets: Cash and cash equivalents $ 9,517 $ — $ — $ 9,517 Short-term investments 53 — — 53 $ 9,570 $ — $ — $ 9,570 At December 31, 2021 Assets: Cash and cash equivalents $ 12,229 $ — $ — $ 12,229 Short-term investments 67 — — 67 $ 12,296 $ — $ — $ 12,296 The Company’s short-term investments consist of the common stock in Fabled and are classified within Level 1 of the fair value hierarchy (see Note 4).

Income Taxes	14. 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. In accordance with ASC 740, the interim provision for taxes was calculated by using the estimated annual effective tax rate applied to the year-to-date income or losses on a jurisdictional basis. Although the Company has generated ordinary losses on a year-to-date basis, the Company has projected taxable income by year end in certain tax jurisdictions, for which an annual effective tax rate has been calculated. For the six months ended June 30, 2022, the Company recognized $44,000 of income tax benefit, of which $17,000 represented a current tax expense and $61,000 was a deferred tax benefit. In accordance with ASC 740, the Company presents deferred tax assets net of its deferred tax liabilities on a tax jurisdictional basis on its Condensed Consolidated Balance Sheets. As of June 30, 2022, the Company had net deferred tax assets of $41,000 and no deferred tax liability on the Condensed Consolidated Balance Sheets, primarily related to the 7.5% special mining tax in Mexico. As of December 31, 2021, the Company had no net deferred tax assets and a net deferred tax liability of $19,000, primarily related to the 7.5% special mining tax in Mexico. The Company, a Delaware corporation, and its subsidiaries file tax returns in the United States and in various foreign jurisdictions. The tax rules and regulations in these countries are highly complex and subject to interpretation. The Company’s income tax returns are subject to examination by the relevant taxing authorities and in connection with such examinations, disputes can arise with the taxing authorities over the interpretation or application of certain tax rules within the country involved. In accordance with ASC 740, the Company identifies and evaluates uncertain tax positions, and recognizes the impact of uncertain tax positions for which there is less than a more-likely-than-not probability of the position being upheld upon review by the relevant taxing authority. Such positions are deemed to be “unrecognized tax benefits” which require additional disclosure and recognition of a liability within the financial statements. The Company had no unrecognized tax benefits at June 30, 2022 or December 31, 2021.

On December 11, 2020, the Company entered into a third amendment of the ATM Agreement further extending the agreement so that it will remain in full force and effect until such time as the ATM Agreement is terminated in accordance with certain other terms therein or upon mutual agreement by the parties, and to reflect a new registration statement on Form S-3 (No. 333-249218). The common stock will be distributed at the market prices prevailing at the time of sale. As a result, prices of the common stock sold under the ATM Program may vary as between purchasers and during the period of distribution.

The RSUs vested on the grant date and each vested RSU entitles the consultant to receive one unrestricted share of common stock upon termination of the consulting agreement with the Company. Key Employee Long-Term Incentive Plan The Company’s 2013 Key Employee Long-Term Incentive Plan (the “KELTIP”) provides for the grant of units (“KELTIP Units”) to certain officers and key employees of the Company, which units will, once vested, entitle such officers and employees to receive an amount, in cash or in Company common stock (such method of settlement at the sole discretion of the Board of Directors) issued pursuant to the Company’s Equity Plan, measured generally by the price of the Company’s common stock on the settlement date. KELTIP Units are not an actual equity interest in the Company and are solely unfunded and unsecured obligations of the Company that are not transferable and do not provide the holder with any stockholder rights. Payment of the settlement amount of vested KELTIP Units is deferred generally until the earlier of a change of control of the Company or the date the grantee ceases to serve as an officer or employee of the Company. The Company intends to settle all the KELTIP Units in common stock of the Company, an option that the Board of Directors holds in its sole discretion so long as sufficient shares remain available under the Equity Plan. As a result, all outstanding KELTIP Units are recorded in equity at June 30, 2022 and December 31, 2021. During the first quarter of 2022, the Company granted 450,000 KELTIP Units to a new officer of the Company. One third of the KELTIP Units granted vested on the grant date with the remaining KELTIP Units vesting one third on each of the first and second anniversaries of the grant. For the six months ended June 30, 2022, the Company recognized approximately $83,000 of stock compensation expense related to the grant and expects to recognize approximately $88,000 of additional expense over the next twenty months. During the second quarter of 2022, the Company granted 500,000 KELTIP Units to another new officer of the Company. The KELTIP Units granted will vest one half on each of the first and second anniversaries of the grant. For the six months ended June 30, 2022, the Company recognized approximately $14,000 of stock compensation expense related to the grant and expects to recognize approximately $186,000 of additional expense over the next twenty-four months. Also, during the six months ended June 30, 2022, an officer of the Company retired and was issued 1,123,380 shares of the Company’s common stock net of 456,620 shares relinquished to cover withholding taxes.

The Company’s warrants allow for the potential settlement in cash if certain extraordinary events are effected by the Company, including a 50% or greater change of control in the Company’s common stock. Since those events have been deemed to be within the Company’s control, the Company continues to apply equity treatment for these warrants.

Sale of Metals and Related Costs During the six months ended June 30, 2022, the Company sold gold and silver contained in doré bars related to the Rodeo operation and recorded revenue of approximately $13.4 million and related costs of approximately $9.0 million. The gold and silver contained in the doré bars were sold to one customer, a metals refinery located in the United States. Under the terms of the Company’s agreement with its customer, title passes and revenue is recognized by the Company when the contractual performance obligations of the parties are completed, generally at the time a provisional or final payment is made. A provisional payment for approximately 95% of the contained gold and silver is made generally within 10 approximately 30 days following the date of shipment when final assays and refinery charges are agreed upon by the parties. A price for the gold and silver sold is set, based on current market prices, at the time a provisional or final payment is made. Refining and transport costs, deducted from the final payments made, are treated as third party agent costs incurred by the Company in performing its obligations under the agreement with its customer after the transfer of control on provisional sales, and are therefore netted against revenue on an accrual basis. During the six months ended June 30, 2021, the Company sold gold and silver contained in doré bars related to the Rodeo operation and recorded revenue of approximately $7.6 million and related costs of approximately $4.9 million.

Commitments and Contingencies	19. Commitments and Contingencies During April 2021, the Company became aware of a lawsuit in Mexico against one of the Company’s Mexican subsidiaries, Minera William, S.A. de C.V. (“Minera William”). The plaintiff in the matter is Unifin Financiera, S.A.B de C.V. (“Unifin”). The lawsuit was assigned to the Fifth Specialized Commercial District Court. Although the Company has knowledge of the existence and content of the lawsuit filed by Unifin, the Court has not officially served Minera William with the complaint as of the date of this report. Unifin is alleging that a representative of Minera William signed certain documents in July 2011 purporting to bind Minera William as a guarantor of payment obligations owed by a third party to Unifin in connection with that third party’s acquisition of certain drilling equipment. At the time the documentation was allegedly signed, Minera William was a subsidiary of ECU Silver Mining prior to the Company’s acquisition of ECU in September 2011. As a preemptive measure, Unifin has obtained a preliminary court order freezing Minera William’s bank accounts in Mexico, which has limited the Company’s and Minera William’s ability to access approximately US$153,000 according to current currency exchange rates. Notwithstanding this action, the restrictions imposed on Minera William’s bank accounts do not impact the Company’s ability to operate the Rodeo mine, which is held through a different Mexico subsidiary, or continue with the Company’s evaluation plans for a potential Velardeña mine restart or move forward with any of the Company’s other exploration programs in Mexico. Unifin is seeking recovery for as much as US$12.5 million. The Company believes there is no basis for this claim and will defend itself if and when the Company is formally served with notice of the lawsuit. As such, the Company has not accrued an amount for this matter in its Condensed Consolidated Balance Sheets or Statements of Operations as of June 30, 2022. At December 31, 2021, the Company had no gain
