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, we are correcting the error 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 $11.7 million reported as “Cash and cash equivalents” on the Condensed Consolidated Balance Sheets at March 31, 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 March 31, 2022 and December 31, 2021: Estimated Carrying March 31, 2022 Cost Fair Value Value (in Investments: Short-term: Trading securities $ 59 $ 91 $ 91 Total trading securities 59 91 91 Total short term $ 59 $ 91 $ 91 December 31, 2021 Investments: Short-term: Trading securities $ 59 $ 67 $ 67 Total trading securities 59 67 67 Total short term $ 59 $ 67 $ 67 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.

Upon receipt of each cash payment, the agreement imposes a performance obligation on the Company to provide Fabled an exclusive right to the Santa Maria Properties to conduct exploration and mining activities during the period from receipt of the payment until the due date of the next required payment. Accordingly, the Company has determined that its performance obligation for each option payment received is satisfied over time. At March 31, 2022, there is a remaining unamortized balance of approximately $1.1 million.

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.

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 March 31, 2022 and December 31, 2021, by respective level of the fair value hierarchy: Level 1 Level 2 Level 3 Total (in thousands) At March 31, 2022 Assets: Cash and cash equivalents $ 11,730 $ — $ — $ 11,730 Short-term investments 91 — — 91 $ 11,821 $ — $ — $ 11,821 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). At March 31, 2022 and December 31, 2021, the Company did not have any financial assets or liabilities classified within Level 2 or Level 3 of the fair value hierarchy.

Income Taxes
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 three months ended March 31, 2022, the Company recognized $85,000 of income tax expense, of which $68,000 represented a current tax expense and $17,000 was a deferred tax expense. 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 March 31, 2022, the Company had no net deferred tax assets and a net deferred tax liability of $36,000 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 March 31, 2022 or December 31, 2021.

Equity Commitment purchase agreement On May 9, 2018, the Company entered into a commitment purchase agreement (the “Commitment Purchase Agreement”) with Lincoln Park Capital (“LPC”), pursuant to which the Company, at its sole discretion, had the right to sell up to $10.0 million of the Company’s common stock to LPC, subject to certain limitations and conditions contained in the Commitment Purchase Agreement (the “LPC Program”). The Company closed on the Commitment Purchase Agreement in July 2018. Under the terms of the agreement, the LPC Program expired as of June 30, 2021. In anticipation of the June 2021 expiration of the agreement, the Company wrote off the remaining balance of $353,000 of deferred LPC Program costs to “ Interest and Other Expense At the Market Offering Agreement In December 2016, the Company entered into an at-the-market offering agreement (as amended from time to time, the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company may, from time to time, issue and sell shares of the Company’s common stock through Wainwright as sales manager in an at-the-market offering under a prospectus supplement for aggregate sales proceeds of up to $5.0 million (the “ATM Program”) or a maximum of 10 million shares. On November 23, 2018, the Company entered into a second amendment of the ATM Agreement, extending the agreement until the earlier of December 20, 2020, or the date that the ATM Agreement is terminated in accordance with the terms therein. 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 ATM Agreement provides that Wainwright will be entitled to compensation for its services at a commission rate of 2.0% of the gross sales price per share of common stock sold. During the first three months of 2022, the Company did not sell shares of common stock under the ATM Program. At March 31, 2022, there was a remaining balance of $70,000 of deferred ATM Program costs, recorded in “ Prepaid expenses and other assets During the first three months of 2021, the Company sold an aggregate of 1,856,960 shares of common stock under the ATM Program at an average price of $0.97 per share of common stock for net proceeds of approximately $1.8 million. Also, during the first three months of 2021, approximately $57,000 of deferred ATM Program costs were amortized. The Company has not sold any shares of common stock under the ATM after March 31, 2021. There is currently approximately $2.2 million remaining available for issuance under the ATM Program based on a prospectus supplement filed with SEC on December 11, 2020. Equity Incentive Plans Under the Company’s Amended and Restated 2009 Equity Incentive Plan (the “Equity Plan”), awards of the Company’s common stock may be made to officers, directors, employees, consultants and agents of the Company and its subsidiaries. The Company recognizes stock-based compensation costs using a graded vesting attribution method whereby costs are recognized over the requisite service period for each separately vesting portion of the award. The following table summarizes the status of the Company’s restricted stock grants issued under the Equity Plan at March 31, 2022 and the changes during the three months then ended: Weighted Average Grant Date Fair Number of Value Per Restricted Stock Grants Shares Share Outstanding at beginning of period 293,334 $ 0.61 Granted during the period — — Restrictions lifted during the period — — Forfeited during the period — — Outstanding at end of period 293,334 $ 0.61 For the three months ended March 31, 2022, the Company recognized approximately $26,000 of stock compensation expense related to the restricted stock grants. The Company expects to recognize additional stock compensation expense related to these awards of approximately $66,000 over the next 18 months. Also, pursuant to the Equity Plan, the Company’s Board of Directors adopted the Non-Employee Director’s Deferred Compensation and Equity Award Plan (the “Deferred Compensation Plan”). Pursuant to the Deferred Compensation Plan, non-employee directors receive a portion of their compensation in the form of Restricted Stock Units (“RSUs”) issued under the Equity Plan. The RSUs generally vest on the first anniversary of the grant and each vested RSU entitles the director to receive one unrestricted share of common stock upon termination of the director’s board service. The following table summarizes the status of the RSU grants issued to Directors of the Company under the Deferred Compensation Plan at March 31, 2022 and the changes during the three months then ended: Weighted Average Grant Date Fair Number of Value Per Restricted Stock Units Shares Share Outstanding at December 31, 2021 4,010,038 $ 0.69 Granted during the period — — Restrictions lifted during the period — — Forfeited during the period — — Outstanding March 31, 2022 4,010,038 $ 0.69 For the three months ended March 31, 2022, the Company recognized approximately $56,000 of stock compensation expense related to the RSU grants. The Company expects to recognize additional stock compensation expense related to the RSU grants of approximately $32,000 over the next 9 months. 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 March 31, 2022 and December 31, 2021. During the three months ended March 31, 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 three months ended March 31, 2022, the Company recognized approximately $69,000 of stock compensation expense related to the grant and expects to recognize approximately $102,000 of additional expense over the next nine months. Also, during the three months ended March 31, 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 shares issued were in settlement of previously granted KELTIP Units. During the three months ended March 31, 2021, the Company granted 480,000 KELTIP Units to two officers of the Company and recognized approximately $0.4 million of stock compensation expense related to the grants. There were 4,200,000 and 5,330,000 KELTIP Units outstanding at March 31, 2022 and December 31, 2021, respectively. Common stock warrants The following table summarizes the status of the Company’s common stock warrants at December 31, 2021 and March 31, 2022, and the changes during the three months then ended: Weighted Number of Average Exercise Underlying Price Per Common Stock Warrants Shares Share Outstanding at December 31, 2021 12,803,846 0.34 Granted during the period — Exercised during period — Expired during period — Outstanding March 31, 2022 12,803,846 $ 0.34 The warrants relate to prior registered offerings and private placements of the Company’s stock. All outstanding warrants are recorded in equity at March 31, 2022 and December 31, 2021 following the guidance established by ASC Topic 815-40. 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.

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 Williams 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 Williams’ 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 March 31, 2022. At December 31, 2021, the Company had no gain
