GOLDEN MINERALS COMPANY

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Expressed in United States dollars)

(Unaudited)

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, 2020 and filed with the SEC on February 18, 2021.

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 7), 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 our 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 that 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 company under SEC criteria since it has not yet demonstrated the existence of proven or probable mineral reserves, as defined by SEC Industry Guide 7, at any of its properties. Until such time, if ever, that the Company demonstrates the existence of proven or probable reserves pursuant to SEC Industry Guide 7, we expect to remain as an exploration stage company.

2. New Accounting Pronouncements

In December 2019, the FASB issued No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). The guidance removes certain exceptions to the general principles of ASC 740 and simplifies several other areas. ASU 2019-12 is effective for public business entities for annual reporting periods beginning after December 15, 2020, and interim periods within those reporting periods.  The Company has adopted ASU 2019-12 beginning in 2021.  One of the amendments within ASU 2019-12 eliminates a limitation on the amount of income tax benefit that can be recognized in an interim period when a year-to-date loss exceeds the anticipated loss for the year.  The Company has applied this guidance in the calculation of the tax benefit included in “Income taxes” in the Condensed

7

Consolidated Statements of Operations.  The adoption of this guidance did not result in a material impact on the Company’s consolidated financial position or results of operations.

During the first quarter 2020, the Company adopted ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 modifies the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. The adoption of this update did not result in a material impact on the Company’s consolidated financial position or results of operations.

On April 12, 2021, the SEC published a statement relating to accounting and reporting considerations for warrants issued by Special Purpose Acquisition Companies (SPACs). The SEC statement raised accounting and reporting considerations for all reporting entities that restrict the use of the exception under ASC 815-40-25-7 thru 8 that allows for equity treatment, under certain conditions, for warrants that allow cash settlement in certain change of control transactions. The restriction put forth by the SEC would prevent equity treatment in cases where cash is received disproportionately between shareholders and warrant holders in such transactions.  All of the outstanding warrants granted by the Company are recorded in equity at September 30, 2021 and December 31, 2020 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.

3.     Cash and Cash Equivalents and Short-term Investments

Of the $8.8 million reported as “Cash and cash equivalents” on the Condensed Consolidated Balance Sheets at September 30, 2021, 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 20.  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 September 30, 2021 and December 31, 2020:

			Estimated		Carrying
September 30, 2021	Cost		Fair Value		Value
		(in thousands)
Investments:
Short-term:
Trading securities	$	59	$	102	$	102
Total trading securities		59		102		102
Total short term	$	59	$	102	$	102
December 31, 2020
Investments:
Short-term:
Trading securities	$	59	$	79	$	79
Total trading securities		59		79		79
Total short term	$	59	$	79	$	79

The short-term investments at September 30, 2021 and December 31, 2020 consist of 1,000,000 common shares of Fabled Silver Gold Corp., formerly known as Fabled Copper Corp. (“Fabled”), a junior mining company that entered into

8

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 7). The 1,000,000 common shares were issued to the Company as partial consideration per the terms of the option agreement.

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.

4.     Prepaid Expenses and Other Assets

Prepaid expenses and other current assets at September 30, 2021 and December 31, 2020 consist of the following:

	September 30,		December 31,
	2021		2020
	(in thousands)
Prepaid insurance	$	276	$	571
Recoupable deposits and other		583		559
	$	859	$	1,130

The September 30, 2021 recoupable deposits and other includes a receivable from Barrick for reimbursement of costs of approximately $0.2 million related to the Earn-in Agreement (see Note 7).

5.     Inventories, net

Inventories at the Rodeo operation at September 30, 2021 and December 31, 2020 consist of the following:

	September 30,		December 31,
	2021		2020
	(in thousands)
Doré inventory	$	927	$	0
In-process inventory		475		0
Material and supplies	$	455	$	284
	$	1,857	$	284

Doré and in-process inventories, recorded at book value, include $25,000 of capitalized depreciation and amortization. Doré inventory at September 30, 2021 consists of 1,010 payable ounces of gold and 2,390 payable ounces of silver.

The materials and supplies inventories at September 30, 2021 and December 31, 2020 are primarily related to the Rodeo operation and are reduced by a $0.3 million obsolescence reserve.

6.Value added tax receivable, net

At September 30, 2021, the Company recorded a net value added tax (“VAT”) paid in Mexico of $1.1 million, related to the Velardeña Properties and the Rodeo operation, as a recoverable asset, which appears in “Value added tax receivable, net” on the Condensed Consolidated Balance Sheets.  Mexico law allows for certain VAT payments to be recovered through ongoing applications for refunds. During the third quarter ended September 30, 2021, the Company recovered approximately $1.5 million of the VAT receivable recorded at June 30, 2021.  The Company expects that the current

9

amounts will be recovered within a one-year period.  At September 30, 2021, the Company recorded approximately $0.4 million of VAT payable as a reduction to the VAT receivable in Mexico.

The Company has also paid VAT in Mexico as well as other countries, primarily related to exploration projects, which has been charged to expense as incurred because of the uncertainty of recoverability.

El Quevar Earn-In Agreement

On April 9, 2020, the Company and several of its directly and indirectly wholly-owned subsidiaries entered into the Earn-in Agreement with Barrick, pursuant to which Barrick has acquired an option (the “Option”) to earn a 70% interest in the Company’s El Quevar project located in the Salta Province of Argentina. Pursuant to the terms of the Earn-in Agreement, in order to earn an undivided 70% interest in the El Quevar project, Barrick must: (A) incur a total of $10 million in work expenditures over a total of eight years ($0.5 million per year in years one and two, $1 million per year in years three, four and five, and $2 million per year in years six, seven and eight); (B) deliver to the Company a National Instrument 43-101 compliant pre-feasibility study pursuant to the parameters set forth in the Earn-in Agreement; and (C) deliver a written notice to exercise the Option to the Company within the term of the Earn-in Agreement. Barrick may withdraw from the Earn-in Agreement at any time after spending a minimum of $1 million in work expenditures and upon providing 30 days’ notice to the Company. The Company will form a new entity (“NewCo”) that will hold the El Quevar properties.  Upon satisfaction of the Earn-in conditions and exercise of the Option, NewCo will be 70% owned by Barrick and 30% owned by the Company. Funding of NewCo will be based on Barrick’s and the Company’s respective ownership and industry standard dilution mechanisms will apply in the case of funding shortfalls by either shareholder.  As of September 30, 2021, Barrick had met the $1 million in work expenditures that would allow them to withdraw from the Earn-in Agreement.  

In connection with the Earn-in Agreement, the Company and Barrick also entered into a Subscription Agreement (the “Subscription Agreement”) dated as of April 9, 2020 pursuant to which Barrick purchased 4,719,207 shares of the Company’s common stock at a purchase price of $0.2119 per share in a private placement transaction (see Note 15).

Sale of Santa Maria Property

On July 14, 2020, the Company entered into a binding letter of intent (“Letter of Intent”) with Fabled for a potential transaction pursuant to which Fabled would acquire the Company’s option to earn a 100% interest in the Santa Maria mining claims located in Chihuahua, Mexico (the “Option”). On December 4, 2020, the Company entered into a definitive option agreement (“Option Agreement”) to sell its option to Fabled.  The period to exercise the Option (the “Exercise Period”) expires on December 4, 2022, unless extended by the parties under the terms of the Option Agreement. As consideration for the Option, Fabled (i) paid $500,000 in cash to the Company and issued to the Company 1,000,000 shares of Fabled’s common stock (the “Closing Consideration”); (ii) will pay $1,500,000 in cash to the Company on the one year anniversary date following the closing of the Option Agreement; (iii) will pay $2,000,000 in cash to the Company on the two year anniversary date following the closing of the Option Agreement; and (iv) upon exercise of the Option, will grant

10

the Company a 1% net smelter return royalty on the Maria, Martia III, Maria II Frac. I, Santa Maria and Punto Com concessions (the “Concessions”).  Pursuant to the Option Agreement, during the Exercise Period, Fabled is obligated to pay to each of the owners of the Concessions any remaining required payments due to the owners pursuant to the various underlying option agreements between the owners and the Company, and to make all payments and perform all other requirements needed to maintain the Concessions in good standing.  As of September 30, 2021, there was approximately $0.2 million of concession payments remaining to be paid by Fabled over the next approximately one year.  Should Fabled not complete its obligations described above, the Santa Maria mining claims will revert to the Company and the Company will be entitled to keep any payments made by Fabled under the terms of the Option Agreement.  

The Company recorded the $0.5 million received from Fabled upon execution of the agreement to Deferred revenue on the accompanying Condensed Consolidated Balance Sheets and is amortizing the amount to income over a one-year period. At September 30, 2021, there is a remaining unamortized balance of approximately $0.1 million.  

8.Other Long-Term Assets

Other long-term assets at September 30, 2021 and December 31, 2020 consist of the following:

	$	820	$	1,472

The deferred offering costs at September 30, 2021 are associated with the ATM Agreement (see Note 15).  The deferred offering costs at December 31, 2020 were associated with the ATM Agreement and the Commitment Purchase Agreement (see Note 15). The Commitment Purchase Agreement expired during June 2021, and as of September 30, 2021 the Company had written off the remaining balance of $353,000 of deferred LPC Program costs to “Interest and Other Expense” on the Condensed Consolidated Statement of Operations.

The right of use assets at September 30, 2021 include approximately $0.4 million related to certain office leases and $0.3 million related to a mining equipment lease at our Rodeo Property.  The right of use assets at December 31, 2020 include approximately $0.5 million related to certain office leases and $0.5 million related to a mining equipment lease at our Rodeo Property.  

The Company took possession of new office space and began a new long-term lease for its principal headquarters office with an effective commencement date of June 1, 2019. The new office lease will expire five years and eight full calendar months following the commencement date. There are no options to extend the lease beyond the stated term. The Company recorded a right of use asset of approximately $465,000 and a lease liability of approximately $450,000 in the second quarter of 2019 based on the net present value of the future lease payments discounted at 9.5%, which represents the Company’s incremental borrowing rate for purposes of applying the guidance of Topic 842. As required, the Company will recognize a single lease cost on a straight-line basis.

The Company also has long-term office leases in Mexico and Argentina that expired in 2019 and recorded a combined lease liability of approximately $45,000 and combined right of use asset of approximately $45,000 relating to both of those leases at January 1, 2019. In November 2019, the Company renewed its Mexican office lease for four years and recorded a right of use asset and lease liability of approximately $174,000. In December 2019, the Company also renewed its Argentina office lease for two years and recorded a right of use asset and lease liability of approximately $18,000.

In December 2020, the Company’s wholly-owned subsidiary, Minera de Cordilleras S. de R.L. de C.V., entered into an agreement with Triturados del Guadiana, S.A de C.V. (“Trigusa”), whereby Trigusa will carry out mining activities at the Rodeo Property.  Per the terms of the mining agreement, Trigusa will provide services for the 27-month period beginning in December 2020 and ending March 31, 2023, with the potential for an extension of time upon mutual agreement of both parties. The Company has determined that the mining agreement contains an embedded lease, relating to the mining equipment provided by Trigusa, per the guidance of ASU 2016-02 and Topic 842. The Company did not elect the practical expedient permitting the combination of lease and non-lease components of the mining agreement.  The

11

Company recorded a right of use asset and a lease liability of approximately $420,000 based on the net present value of the future lease payments discounted at 7.0%, which represents the Company’s incremental borrowing rate.

The lease liabilities noted above have been included in “Other liabilities”, short term and long term (Note 11), in the Company’s Consolidated Balance Sheets at September 30, 2021 and December 31, 2020.

11.     Other Liabilities

Other Current Liabilities

The following table sets forth the Company’s other current liabilities at September 30, 2021 and December 31, 2020:

	September 30,		December 31,
	2021		2020
	(in thousands)
Premium financing	$	—	$	390
Office lease liability		146		138

In June 2020, the Company financed $110,000 of its premium for general liability insurance. The premium was payable in twelve equal payments at an interest rate of 5.74% per annum. At December 31, 2020, the remaining balance, plus accrued interest, was approximately $23,000. In December 2020 the Company financed approximately $406,000 of its premium for directors and officers’ insurance. The premium is payable in eight equal payments at an interest rate of 5.74% per annum. At September 30, 2021, the remaining balance for both policies, plus accrued interest, had been paid in full.

The office lease liability is related to lease liabilities for office space at the Company’s principal headquarters in Golden, Colorado and in Mexico and Argentina.

The mining equipment lease liability is related to equipment used by the contract miner at our Rodeo property (see Note 8).

Other Long-Term Liabilities

Other long-term liabilities of $0.4 million for the period ended September 30, 2021, consist of approximately $0.1 million related to the mining equipment lease liability at our Rodeo Property and $0.3 million related to lease liabilities for office space at the Company’s principal headquarters in Golden Colorado and in Mexico and Argentina (see Note 8).

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.

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 nine months of 2021, the Company recognized approximately $196,000 of accretion expense.

13

The following table summarizes activity in the Velardeña Properties ARO:

	Nine Months Ended
	September 30,
	2021		2020
	(in thousands)
Beginning balance	$	3,156	$	2,825
Changes in estimates, and other		(86)		82
Accretion expense		196		184
Ending balance	$	3,266	$	3,091

The change in estimates of the ARO recorded during 2021 and 2020 are 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 September 30, 2021 and December 31, 2020 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 nine-month periods ended September 30, 2021 or September 30, 2020.

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:  Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2:  Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

Level 3:  Unobservable inputs due to the fact that there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

The following table summarizes the Company’s financial assets and liabilities at fair value on a recurring basis at September 30, 2021 and December 31, 2020, by respective level of the fair value hierarchy:

	Level 1		Level 2		Level 3		Total
	(in thousands)
At September 30, 2021
Assets:
Cash and cash equivalents	$	8,800	$	—	$	—	$	8,800
Short-term investments		102		—		—		102
	$	8,902	$	—	$	—	$	8,902
At December 31, 2020
Assets:
Cash and cash equivalents	$	9,704	$	—	$	—	$	9,704
Short-term investments		79		—		—		79
	$	9,783	$	—	$	—	$	9,783

14

The Company’s cash equivalents, comprised principally of U.S. treasury securities, are classified within Level 1 of the fair value hierarchy.

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 3).

At September 30, 2021 and December 31, 2020, the Company did not have any financial assets or liabilities classified within Level 2 or Level 3 of the fair value hierarchy.

Non-recurring Fair Value Measurements

There were no non-recurring fair value measurements at September 30, 2021 or December 31, 2020.

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 nine months ended September 30, 2021, the Company recognized $203,000 of income tax expense, of which $162,000 represented a current tax expense and $41,000 was a deferred tax expense. Of the total amount for the nine months ended September 30, 2020 the Company recognized $18,000 of income tax expense, all of which was a current 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 September 30, 2021, the Company had no net deferred tax assets or net deferred tax liabilities on the Condensed Consolidated Balance Sheets, and as of December 31, 2020, the Company had no net deferred tax assets or net deferred tax liabilities reported on its balance sheet.

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 September 30, 2021 or December 31, 2020.

15.     Equity

Public offering

On July 21, 2020, the Company entered into an Amended and Restated Underwriting Agreement (the “Underwriting Agreement”) with H.C. Wainwright & Co., LLC as representative of the underwriters named therein (the “Underwriters”), providing for the issuance and sale by the Company in a firm commitment offering (the “Offering”) of 17,857,143 shares of common stock at a price to the public of $0.42 per share (the “Offering Shares”). In addition, the Company granted the Underwriters an option to purchase, at the public offering price per share of common stock, up to an additional 2,678,571 shares of common stock, exercisable for 30 days from the date of the Underwriting Agreement (the “Option Shares”).  The Offering Shares and Option Shares were registered pursuant to the Company’s registration statement on Form S-3 (File No. 333-220461), and a prospectus supplement thereto filed with the Securities and Exchange Commission.  On July 24, 2020, the Underwriters acquired the Offering Shares and the full amount of the Option Shares from the Company.  After the underwriting discount of 6% and total offering expenses of approximately $155,000 the Company received net proceeds of approximately $8.0 million from the sale of the Offering Shares and the Option Shares.  

15

Subscription agreement

In connection with the Earn-in Agreement (see Note 7), the Company and Barrick entered into the Subscription Agreement dated as of April 9, 2020 pursuant to which Barrick purchased 4,719,207 shares of the Company’s common stock at a purchase price of $0.2119 per share in a private placement transaction. The shares were offered and sold without registration under the Securities Act of 1933, as amended (the “Act”) in reliance on the exemptions provided by Section 4(a)(2) of the Act and/or Regulation D promulgated thereunder. The net proceeds of the Subscription Agreement of approximately $0.9 million were recorded in equity.

Offering and private placement

On April 20, 2020, the Company entered into a securities purchase agreement with certain institutional investors providing for the issuance and sale of 15,000,000 shares of the Company’s common stock at a price of $0.20 per share, and in a concurrent private placement transaction, the issuance of an aggregate of 11,250,000 warrants, ultimately consisting of 7,500,000 series A warrants and 3,750,000 series B warrants (collectively, the “Warrants”), to purchase up to 11,250,000 shares of our common stock at an exercise price of $0.30 per share, for aggregate gross proceeds of $3.0 million (the “Offering”). Each Warrant is exercisable six months from the date of issuance on April 22, 2020 and has a term expiring five years after such initial exercise date. The Warrants contain so-called full-ratchet anti-dilution provisions which may be triggered upon any future issuance by the Company of shares of its common stock or common stock equivalents at a per share price below the then-exercise price of the Warrant, subject to certain exceptions; provided, however, that with respect to the Series B warrants, the adjusted exercise price will not be less than $0.26.

The net proceeds of the Offering were recorded in equity. Total costs for the Offering were approximately $334,000, including listing fees, legal and other costs, and the placement agent fee of six percent of aggregate gross proceeds; however, a reduced fee was accepted with respect to one investor. All such costs were recorded as a reduction to “Additional paid in capital” on the Condensed Consolidated Balance Sheets.  Using the Black Scholes model, and assuming no triggering events take place to reduce the exercise price of the Warrants, the fair value of the combined Series A and Series B warrants issued was approximately $1.9 million on April 22, 2020, the date of issuance of the Warrants. The Black Scholes inputs included the closing stock price on April 22, 2020 (the date of issuance of the Warrants) of $0.24, the exercise price and exercise period of the Warrants, the Company’s applicable volatility rate for the period of the Warrants of 95%, and the applicable risk-free rate of 0.41%.

Commitment purchase agreement

On May 9, 2018, the Company entered into a commitment purchase agreement (the “Commitment Purchase Agreement”) with 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.

During the nine months ended September 30, 2021, the Company did not sell any shares of common stock to LPC under the Commitment Purchase Agreement. 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” on the Condensed Consolidated Statement of Operations during the three-month period ended March 31, 2021.  

During the nine months ended September 30, 2020, the Company sold 900,000 shares of common stock to LPC under the Commitment Purchase Agreement at an average sales price per share of approximately $0.27, resulting in net proceeds of approximately $216,000.  In addition, approximately $24,000 of Commitment Purchase Agreement costs were amortized, resulting in a remaining balance of $353,000 of deferred LPC Program costs, recorded in “Other long-term assets” on the Condensed Consolidated Balance Sheets as of September 30, 2020.

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

16

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 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.  At September 30, 2021 there was a remaining balance of $71,000 of deferred ATM Program costs, recorded in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheets as of September 30, 2021.

During the first nine months of 2020, the Company sold an aggregate of 823,452 shares of common stock under the ATM Agreement at an average price of $0.28 per share of common stock for net proceeds of approximately $223,000.  In addition, approximately $8,000 of deferred ATM Program costs were amortized, resulting in a remaining balance of $129,000 of deferred ATM Program costs, recorded in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheets as of September 30, 2020.

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 September 30, 2021 and the changes during the nine months then ended:

		Weighted
		Average Grant
		Date Fair
	Number of	Value Per
Restricted Stock Grants	Shares	Share
Outstanding at December 31, 2020	224,002	$	0.36

Restrictions lifted during the period	(265,668)		0.47
Forfeited during the period	—		—
Outstanding September 30, 2021	293,334	$	0.61

For the nine months ended September 30, 2021, the Company recognized approximately $139,000 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 $98,000 over the next 21 months. During the nine months ended September 30, 2021, 335,000 shares were granted to nine employees, with one-third of the grants vesting on the grant date and the remaining shares vesting equally on the first and second anniversaries of the grant date. Also during the period, restrictions were lifted on the normal vesting of 154,002 shares granted to six employees in prior years.

17

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 September 30, 2021 and the changes during the nine months then ended:

		Weighted
		Average Grant

For the nine months ended September 30, 2021, the Company recognized approximately $162,000 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 $127,000 over the next 9 months. During the nine months ended September 30, 2021, 50,000 RSUs were granted to each of the six board members for a total of 300,000 RSUs.

During the nine months ended September 30, 2021, the Company granted a consultant 100,000 RSUs and recognized $67,000 of stock compensation expense. 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 September 30, 2021 and December 31, 2020.

During the nine-month period ended September 30, 2021, the Company granted 1,605,000 KELTIP Units to two officers of the Company and recognized approximately $1.0 million of stock compensation expense related to the grants.  During the nine-month period ended September 30, 2020, the Company granted 1,400,000 KELTIP Units to two officers of the Company and recognized approximately $0.5 million of stock compensation expense related to the grants. There were 5,330,000 and 3,725,000 KELTIP Units outstanding at September 30, 2021 and December 31, 2020, respectively.

Outstanding September 30, 2021	14,303,846	$	0.39

The warrants relate to prior registered offerings and private placements of the Company’s stock.

As discussed above under “Equity – Offering and private placement”, on April 20, 2020, the Company entered into a securities purchase agreement with certain institutional investors providing for the issuance and sale of 15,000,000 shares of the Company’s common stock and in a concurrent private placement transaction, the issuance of an aggregate of 11,250,000 warrants, ultimately consisting of 7,500,000 series A warrants and 3,750,000 series B warrants.  During the year ended December 31, 2020, and the nine months ended September 30, 2021, 6,400,000 series A warrants and 3,500,000 series B warrants were exercised leaving a balance of 1,100,000 and 250,000 series A and series B warrants outstanding, respectively as of September 30, 2021.

On July 17, 2019, the Company issued 8,653,846 registered shares of common stock in a registered direct offering. In connection with the offering, each investor received an unregistered Series A warrant to purchase a share of common stock for each share of common stock purchased. Each Series A warrant is exercisable six months from the date of issuance and has a term expiring in January 2025.  During the nine months ended September 30, 2021, 200,000 series A warrants were exercised, leaving a balance of 8,453,846 series A warrants outstanding.

In May 2016, the Company issued 8.0 million registered shares of common stock at a purchase price of $0.50 per share in a registered direct offering resulting in gross proceeds of $4.0 million. In connection with the offering, each investor received an unregistered warrant to purchase three-quarters of a share of common stock for each share of common stock purchased. The resulting 6,000,000 warrant shares have an exercise price of $0.75 per share, became exercisable on November 7, 2016 and were exercisable until November 6, 2021, five years from the initial exercise date. In connection with a July 2019 registered direct offering, the Company agreed to exchange, on a one-for-one basis, 4,500,000 of the May 2016 warrants for Series B warrants to purchase 4,500,000 shares of common stock at an exercise price of $0.35 per share. Each Series B warrant is exercisable six months from the date of issuance and has a term expiring in May 2022.  During the nine months ended September 30, 2021, 1,500,000 series B warrants were exercised leaving a balance of 3,000,000 series B warrants and 1,500,000 of the original July 2016 warrants outstanding, respectively.

All outstanding warrants are recorded in equity at September 30, 2021 and December 31, 2020 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.

16. Sale of Metals and Related Costs

During the nine months ended September 30, 2021, the Company sold gold and silver contained in doré bars related to the Rodeo operation and recorded revenue of approximately $16.1 million and related costs of approximately $9.2 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 10-12 days after the product is shipped and customary sales documents are completed.  A final payment is made within 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.

Costs related to the sale of metals products include direct and indirect costs incurred to mine, process and market the products.  

During the nine months ended September 30, 2020 the Company did not sell any doré products or incur any related costs.

17.      Oxide Plant Lease Revenue and Related Costs

For the nine months ended September 30, 2020, the Company recorded revenue of approximately $4.6 million and related costs of approximately $1.6 million associated with the lease of the Velardeña Properties oxide plant. The Company recognizes oxide plant lease fees and reimbursements for labor, utility and other costs as “Revenue: Oxide plant lease” in the Condensed Consolidated Statements of Operations following the guidance of ASC 842.  ASC 842 supports recording as gross revenue the reimbursement of expenses incurred directly by the Company in performing its obligations under the lease in situations where the entity has control over the specific goods or services transferred to a customer as a principal versus as an agent. The actual costs incurred for reimbursed direct labor and utility costs are reported as “Oxide plant lease costs” in the Condensed Consolidated Statements of Operations. The Company recognizes lease fees during the period the fees are earned per the terms of the lease.

On July 7, 2020, the Company received notification from Hecla terminating the Lease Agreement pursuant to the Third Amendment, effective November 30, 2020. Therefore, during the nine months ended September 30, 2021 the Company did not record any income or costs associated with the lease of the oxide plant to Hecla.

18.     Interest and Other Expense, Net

For the nine months ended September 30, 2021, the Company recognized approximately $0.3 million of Interest and Other Expense primarily related to the write off of deferred costs related to the LPC Program (see Note 15).  

For the nine months ended September 30, 2020 the Company recognized approximately $0.1 million Interest and Other Expense primarily related to amounts payable to Sentient (see Notes 11) and interest on a refundable deposit to Autlán.

20.     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

21

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 September 30, 2021.

On April 23, 2021, a new labor law was made official in Mexico that will impact companies that utilize subcontractor structures, effective beginning August 1, 2021.  The Company utilizes subcontractor structures in Mexico, as is common practice among companies in the mining and other industries in Mexico.  The law will disallow a deduction in computing income taxes for labor outsourcing costs, unless the arrangement falls within certain narrowly defined exceptions.  The new law does provide for annual caps on the amount of employee profit sharing a company would be required to pay, which is designed to even out the profit sharing liability over several years.  As of September 30, 2021, the Company has reorganized the functions performed by its various Mexican subsidiaries to comply with the new law.  The Company estimates its profit sharing liability in Mexico will increase for the full year 2021 as a result of the new law taking effect and the completion of the Company’s reorganization process and has accrued approximately $136,000 for such amount, included in “Accounts payable and other accrued liabilities” in the Company’s Consolidated Balance Sheets at September 30, 2021.  

At December 31, 2020, the Company had no gain or loss contingencies.  The Company has certain purchase and lease commitments as set forth in the Company’s Form 10-K for the year ended December 31, 2020.

21.     Segment Information

The Company’s sole activity is the mining, construction and exploration of mineral properties containing precious metals. The Company’s reportable segments are based upon the Company’s revenue producing activities and cash consuming activities. The Company reports two segments, one for its revenue producing activities in Mexico, which includes both the Velardeña Properties and the Rodeo Property, and the other comprised of non-revenue producing activities, including exploration, construction and general and administrative activities. Intercompany revenue and expense amounts have been eliminated within each segment in order to report on the basis that management uses internally for evaluating segment performance.

The financial information relating to the Company’s segments is as follows:

22.     Related Party Transactions

The following sets forth information regarding transactions between the Company (and its subsidiaries) and its officers, directors and significant stockholders.

Administrative Services, Lease of Equipment:

Beginning in August 2016, the Company began providing limited accounting and other administrative services to Minera Indé, an indirect subsidiary of Sentient.  At September 30, 2021, Sentient, through the Sentient executive funds, holds approximately 23% of the Company’s 162.5 million shares of issued and outstanding common stock.  The administrative services are provided locally in Mexico by the administrative staff in the Company’s Mexico office. The Company charges Minera Indé $15,000 per month for the services, which provides reimbursement to the Company for its costs incurred plus a small profit margin. The Company also leases, from time to time, certain nonessential mining equipment to Minera Indé. Amounts received under the arrangement reduce costs incurred for exploration.  The Company’s Board of Directors and Audit Committee approved the agreement. For the nine months ended September 30, 2021 and 2020, the Company charged Minera Indé approximately $204,000 for services and the use of equipment, offsetting costs that are recorded in “Exploration expense” in the Condensed Consolidated Statements of Operations.

Debt – Related Party

On March 30, 2020, the Company entered into a short-term loan agreement with Sentient whereby the Company received an unsecured loan in the amount of $1,000,000. The Sentient Loan had an interest rate of 10% per annum and was due in full, together with accrued interest and any other amount outstanding under the loan agreement, on December 31, 2020. During August 2020, the Company paid in full the principal amount of the loan plus accrued interest. See Note 10 for a full description of the loan.

Item 2.     Management's Discussion and Analysis of Financial Condition and Results of Operations

Our Company

We were incorporated in Delaware in March 2009 under the Delaware General Corporation Law. During the nine months ended September 30, 2021, our principal source of revenue was from the sale of gold and silver from our Rodeo Property in Durango, Mexico. We incurred net operating losses for the nine months ended September 30, 2021 and 2020.

We remain focused on mining operations at the Rodeo Property as well as further studies of a restart plan for Velardeña including the use of bio-oxidation to improve the payable gold recovery.  We also continue 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 Velardeña Properties. We are also focused on advancing our El Quevar exploration property in Argentina through the Earn-In Agreement with Barrick and on advancing selected properties in our portfolio of approximately 12 properties, located in Mexico, Nevada and Argentina. We are reviewing strategic opportunities, focusing primarily on development or operating properties in North America, including Mexico.

This discussion should be read in conjunction with Management’s Discussion and Analysis included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 18, 2021.

2021 Highlights

Rodeo Property

We began mining activities at the Rodeo Property, using a contract miner, in December 2020. In November 2020 we received the final necessary permits for us to commence mining at the Rodeo Property from SEMARNAT, the environmental protection agency in Mexico. We began hauling the mined material, also using a contractor, for processing at our Velardeña oxide plant beginning in January 2021.  We provide the overall mine management and engineering, which includes in-pit technicians who determine whether material is suitable for process or placement on the waste dump.  We also employ and supervise the workforce responsible for processing activities at our oxide plant.  Our assay lab, located in Velardeña, Durango, Mexico is used for the project’s assaying requirements.  We poured our first doré bar at the end of January 2021 and completed our first shipment of doré to a refinery located in the United States in March 2021.  

We installed a new regrind mill circuit at the plant specifically designed to process the harder mined material coming from the Rodeo Property, which was completed in April at a total cost of approximately $1.2 million.  The new circuit, which was fully operational at the end of April, allowed us to increase daily throughput of Rodeo material in the oxide plant to at least 500 tonnes per day.  Mill throughput in third quarter 2021 averaged 532 tonnes per day, and at that higher throughput level, the current life of the Rodeo mine is estimated to run through the first quarter of 2023 (approximately 2.25 years from initial mining), unless additional resources are discovered.

Assays from processing at the oxide plant indicate the doré produced to date are comprised of approximately 20 to 25 percent gold and 65 to 75 percent silver and are of a quality that is readily marketable and saleable to refineries located either in Mexico or internationally, consistent with standard commercial terms. We entered into a refining agreement with a third party in February 2021 and have completed 23 shipments of doré as of November 4, 2021.

The following table highlights additional non-GAAP cost and revenue statistics related to the Rodeo operations: 

		Three Months Ended September 30, 2021	Nine Months Ended September 30, 2021

Total cash operating costs per tonne processed	$	88	$	99
(1) Cash costs, net of by-product credits, per payable ounce of gold is a non-GAAP financial measure

Total cash operating costs for the nine months ended September 30, 2021, as depicted in the table above, include all production costs during the period, including mining, milling and general and administrative costs related to the initial start-up of operations and associated build-up of mined material stockpiles as well as in-solution inventories at the plant.  Unit costs continued to decrease during the three months ended September 30, 2021 as production continued to ramp up.

We anticipate total tonnes processed for the full year 2021 will be approximately 145,000 to 150,000, which is higher than the previously forecasted range of 135,000 to 140,000.  However, due primarily to lower projected full year 2021 mill recoveries for gold of approximately 80%, as compared to our previous projections based on PEA results of approximately 85%, payable production for the full year 2021 is expected to be at the higher end of our prior guidance of 12,000 to 14,000 ounces of gold and above our prior guidance of 25,000 to 30,000 ounces of silver.   Gold recoveries have been slightly lower year to date as we continue to balance the operating performance of the plant between higher throughput and recovery.  We continue to optimize the mill circuit for increased recovery with a focus on a finer grind and additional aeration in the leach tank train.

Using an assumed gold price of $1,800/oz and an assumed silver price of $25.00/oz (our realized prices for the nine months ended September 30, 2021, as shown above, were $1,797 and $25.64 for gold and silver, respectively), estimated operating margin for the full year 2021 from the Rodeo Property (defined as revenue from the sale of metals less the cost of metals sold) is estimated at approximately $10.0 million to $11.5 million with after-tax net cash flow from Rodeo for the full year, net of capital expenditures and working capital, estimated at approximately $8.0 million to $9.0 million, consistent with prior guidance provided in our Form 10-Q for the quarter ended June 30, 2021.

The estimates detailed above are based primarily on the actual results of operations through September 30, 2021. Actual future results from production at Rodeo may vary significantly based upon, among other things, unanticipated variations in grade, unexpected challenges associated with our proposed mining plan, volatility in commodity prices, variations in expected recoveries, increases in projected operating costs, working capital or capital costs or delays in commencement of or interruptions in production.  See “Risk Factors – Risk Factors related to our Mining and Processing Activities” as described in our Form 10-K for the period ended December 31, 2020.

Non-GAAP Financial Measures

Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by generally accepted accounting principles. These measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.

“Total cash costs, net of by-product credits, per payable gold ounce”, and “All-in sustainable costs, net of by-product credits, per payable gold ounce”, are non-GAAP financial measures calculated by the Company as set forth below and may not be comparable to similar measures reported by other companies.

“Total cash costs, net of by-product credits, per payable gold ounce,” includes all direct and indirect operating cash costs associated with the physical activities that would generate doré products for sale to customers, including mining to gain access to mineralized materials, mining of mineralized materials and waste, milling, third-party related treatment, refining and transportation costs, on-site administrative costs and royalties. Total cash costs do not include depreciation, depletion, amortization, exploration expenditures, reclamation and remediation costs, sustaining capital, financing costs, income taxes, or corporate general and administrative costs not directly or indirectly related to the Rodeo project. By-product credits include revenues from silver contained in the products sold to customers during the period. “Total cash costs, net of by-product credits”, are divided by the number of payable gold ounces generated by the plant for the period to arrive at “Total cash costs, net of by-product credits, per payable gold ounce.”

“All-in sustainable costs per payable gold ounce, net of by-product credits” begins with “Total cash costs, net of by-product credits, per payable gold ounce”, and includes capital and sustaining capital.

“Cost of metals sold”, reported as a separate line item in our Condensed Consolidated Statements of Operations for the nine-month period ended September 30, 2021, is the most comparable financial measure, calculated in accordance with GAAP, to “Total cash costs, net of by-product credits”. “Cost of metals sold” includes adjustments for changes in inventory and excludes third-party related treatment and refining costs, which are reported as part of revenue in accordance with GAAP.  The following table presents a reconciliation for the nine months ended September 30, 2021 between the non-GAAP measure of “Total cash cost, net of by-product credits” to the most directly comparable GAAP measure, “Cost of metals sold”.

Rodeo Exploration

In October 2021, we completed an exploration drilling program at Rodeo aimed at expanding the resource.  The program included about 5,680 meters in 82 shallow holes at selected near-surface targets located immediately adjacent to the current pit. In June, August, and October 2021, we announced the results from the drilling program, which included several potentially resource-grade intercepts on the north, south and west sides of the currently planned open pit.  In July, to accelerate the program, we added a reverse circulation (RC) drill because the progress of core drilling has been slower than expected due to the highly silicified nature of the host rock. The drill program included 47 RC holes totaling 3,187 meters and 35 core holes totaling 2,493 meters.  We believe the program has the potential to modestly extend the life of the Rodeo mine beyond the currently estimated life of around 2.25 years.  Full results will be available in Q4 2021, and any newly added resources will be incorporated into the Company’s production plans.

Velardeña

The Velardeña Properties contain two underground mines that were last operated in late 2015, at which point mining activities were suspended when a combination of low metals prices, mining dilution and metallurgical challenges rendered operations unprofitable. We elected to preserve the asset for future use, and since that time we have evaluated and tested various mining methods and processing alternatives that could enable sustainable profitable operations.  

The recent rise in precious metals prices, the advancement of alternative processing technologies in the industry, and the results of our testing activities prompted us to pursue the preparation of an updated preliminary economic assessment (PEA) based partly on projected increased gold recoveries from a proposed bio-oxidation circuit to treat gold-bearing pyrite concentrates. In April 2020, we announced positive results from the updated PEA.

In June we began limited scale mining activities at our Velardeña underground mine to obtain further bulk samples for use in final optimization of the bio-oxidation plant design and for use in additional flotation separation studies that will indicate how we can best separate the gold-bearing minerals into the pyrite-arsenopyrite concentrate that is proposed for processing in the bio-oxidation circuit.  We are also testing mining methods to ensure that we can effectively control

28

mining dilution to obtain the head grades that we expect based on our PEA study.  We expect to have the results of these studies in early 2022.  No development decision has yet been made regarding a potential restart of the Velardeña mines.  

Yoquivo

In September 2020, we began a 3,400-meter, 15-hole drill program to test the most promising portions of certain veins in the Yoquivo property in Chihuahua, Mexico. We completed the drill program in December 2020 and identified four separate vein systems in which surface sampling has returned grades up to 4,050 g/t silver and 27.7 g/t gold from surface. Of substantial interest is the discovery of a new vein parallel to and east of the Pertenencia vein. While the other principal veins have been partially mined from surface to the water table (up to 130 meters) in the case of San Francisco and Pertenencia, and over a much less extensive vertical interval in the case of El Dolar and Esperanza, the new vein is unmined from surface. We began a second phase drill program in October 2021, planned to be about 2,500 meters of core drilling.  

El Quevar

On April 2020, we entered into the Earn-in Agreement with Barrick, pursuant to which Barrick has acquired an option to earn a 70% interest in the Company’s El Quevar project located in the Salta Province of Argentina (the “Option”).  For a description of the Earn-In Agreement, see our Annual Report Form 10-K for the year ended December 31, 2020.  During the earn-in period, in addition to the exploration spending, Barrick will fund the holding costs of the property, which will qualify as work expenditures. Barrick will reimburse us for expenses related to maintaining the exploration camp, which will initially be run by us under a service agreement, and which will also qualify as work expenditures.  Through September 30, 2021, approximately $0.9 million of expenses incurred by us have been or are expected to be reimbursable under the Earn-in Agreement. As of September 30, 2021, Barrick had met the $1 million in work expenditures that would allow them to withdraw from the Earn-in Agreement.

Sarita Este

In December 2019 we paid $150,000 to enter into an option agreement with Cascadero Minerals Corporation (“Cascadero”) to acquire a 51% interest in the gold/copper Sarita Este concession, located in the northwest portion of the Province of Salta, Argentina, located near the Taca Taca project owned by First Quantum Minerals.  The option agreement calls for us to spend at least $0.3 million in exploration expenditures and complete a 2,000-meter drill program by the end of 2021, another $0.5 million by the end of 2022, and another approximately $1.6 million by 2023 for a total $2.5 million.    

We are finishing a 2,500-meter core drilling program in 10 drill holes on the Sarita Este property. The last hole is still in progress.  We are targeting a copper porphyry system in the northeast portion of the Sarita Este claim at the Kachi target and a high sulfidation gold-silver system in the southern portion of the concession at the Sico target.  We expect to release data for those holes completed and an update of our plans for continuing exploration at Sarita Este later in the fourth quarter 2021.

Financial Results of Operations

For the results of continuing operations discussed below, we compare the results from operations for the three and nine months ended September 30, 2021, to the results from operations for the three and nine months ended September 30, 2020.  

Three Months Ended September 30, 2021

Revenue from the sale of metals.  We recorded $8.5 million in revenue from doré sales for the three months ended September 30, 2021. We did not record any revenue from doré sales for the three months ended September 30, 2020.

Costs of metals sold.  For the three months ended September 30, 2021 we recorded $4.3 million of costs of metals sold.  We did not record any cost of metals sold during the three months ended September 30, 2020.  

Revenue from oxide plant lease. We recorded revenue of $2.1 million during three-month period ended September 30, 2020, related to the lease of our Velardeña oxide plant to a third party. The Velardeña oxide plant lease was terminated in November 2020. We did not record any revenue during the three-month period ended September 30, 2021.

29

Oxide plant lease costs. We recorded $0.6 million of costs related to the oxide plant lease during the three-month period ended September 30, 2020. The costs consist primarily of reimbursable labor and utility costs which for accounting purposes are also included in revenue from the oxide plant lease. The Velardeña oxide plant lease was terminated in November 2020. We did not record any costs related to the oxide plant lease during the three-month period ended September 30, 2021.

Exploration expense. Our exploration expense, including property holding costs and allocated administrative expenses, totaled $2.1 million and $1.2 million for the three months ended September 30, 2021, and September 30, 2020, respectively.  The higher exploration expense for 2021 is primarily related to increased exploration at our Velardeña Properties, Rodeo operation in Mexico and Sarita Este property in Argentina during the period.

Velardeña care and maintenance costs. We recorded $0.4 million and $0.2 million for the three-month periods ended September 30, 2021 and September 30, 2020, respectively, for expenses related to care and maintenance at our Velardeña Properties as the result of the suspension of mining and processing activities in November 2015.

El Quevar project expense. We incurred $0.1 million and $0.1 million for the three-month periods ended September 30, 2021, and September 30, 2020, respectively, related to holding and evaluation costs for the Yaxtché deposit at our El Quevar project in Argentina. During the three months ended September 30, 2021 and September 30, 2020, approximately $0.2 million and $0.1 million of costs actually incurred were offset by reimbursements from Barrick, respectively as discussed above.

Administrative expense.  Administrative expenses totaled $0.9 million for the three months ended September 30, 2021. Administrative expenses, including costs associated with being a public company, are incurred primarily by our corporate activities in support of the Rodeo Property, Velardeña Properties, El Quevar project and our exploration portfolio. The $0.8 million of administrative expenses we incurred during the three months ended September 30, 2021, is comprised of $0.3 million of employee compensation and directors’ fees, $0.3 million of professional fees and $0.3 million of insurance, rents, travel expenses, utilities and other office costs. Administrative expenses totaled $0.9 million for the three months ended September 30, 2020. The $0.9 million of administrative expenses we incurred during the three months of 2020 is comprised of $0.2 million of employee compensation and directors’ fees, $0.4 million of professional fees and $0.3 million of insurance, rents, travel expenses, utilities and other office costs.  

Stock based compensation. During each of the three-month periods ended September 30, 2021, and September 30, 2020 we incurred approximately $0.1 million of expense related to stock-based compensation. Stock based compensation varies from period to period depending on the number and timing of shares granted, the type of grant, the market value of the shares on the date of grant and other variables. Stock based compensation was higher in the 2021 period due primarily to stock awards granted to executives and a consultant.

Reclamation and accretion expense. During each of the three months ended September 30, 2021, and September 30, 2020 we incurred approximately $0.1 million of reclamation expense related to the accretion of an asset retirement obligation at the Velardeña Properties and environmental liabilities associated with the Rodeo operation.

Other operating income (expense), net. We recorded $0.1 million of other operating income for the three months ended September 30, 2021, primarily related to the amortization of deferred income related to the option agreement for the sale of the Santa Maria property, as discussed above.  We recorded a nominal amount of other operating expense for the three months ended September 30, 2020, primarily related to the sale of equipment in Argentina.

Depreciation, depletion and amortization. During the three-month periods ended September 30, 2021, and September 30, 2020, we incurred depreciation, depletion and amortization expense of approximately $0.1 million and $0.2 million, respectively.  

Interest and other expense, net. We recorded a nominal amount of interest and other expense, net for both the three-month periods ended September 30, 2021 and September 30, 2020.

Gain (Loss) on foreign currency losses. We recorded a foreign currency gain of approximately $0.1 million for the three months ended September 30, 2021. We recorded a nominal foreign currency loss for the three months ended September 30, 2020. Foreign currency gains and losses are primarily related to the effect of currency fluctuations on monetary transactions incurred by our foreign subsidiaries that are denominated in currencies other than US dollars.

30

Income taxes. We recorded a $188,000 tax expense for the three months ended September 30, 2021, and $18,000 of tax expense for the three months ended September 30, 2020.

Nine Months Ended September 30, 2021

Revenue from the sale of metals.  We recorded $16.1 million in revenue for the nine months ended September 30, 2021, all from the sale of gold and silver bearing doré from the Rodeo Operation in Mexico. We did not record any revenue from doré sales for the nine months ended September 30, 2020.

Costs of metals sold.  For the nine months ended September 30, 2021, we recorded $9.2 million of costs of metals sold. We did not record any cost of metals sold during the nine months ended September 30, 2020.  

Revenue from oxide plant lease. We recorded revenue of $4.6 million during nine-month period ended September 30, 2020, related to the lease of our Velardeña oxide plant to a third party. The Velardeña oxide plant lease was terminated in November 2020. We did not record any costs related to the oxide plant lease during the nine-month period ended September 30, 2021.

Oxide plant lease costs. We recorded $1.6 million of costs related to the oxide plant lease during the nine-month period ended September 30, 2020. The costs consist primarily of reimbursable labor and utility costs which for accounting purposes are also included in revenue from the oxide plant lease. The Velardeña oxide plant lease was terminated in November 2020. We did not record any costs related to the oxide plant lease during the nine-month period ended September 30, 2021.

Exploration expense. Our exploration expense, including work at Rodeo and other properties, property holding costs and allocated administrative expenses, totaled $4.0 million and $3.7 million for the nine months ended September 30, 2021, and September 30, 2020, respectively.  The higher exploration expense for 2021 is primarily related to increased exploration at our Velardeña Properties and Rodeo operation in Mexico and Sarita Este property in Argentina during the period.

El Quevar project expense. For the nine months ended September 30, 2021, and September 30, 2020, we incurred $0.2 million and $0.6 million, respectively related to holding and evaluation costs for the Yaxtché deposit at our El Quevar project in Argentina. During the nine months ended September 30, 2021, and September 30, 2020, approximately $0.5 million and $0.2 million of costs were reimbursed by Barrick, respectively as discussed above.

Velardeña care and maintenance costs. We recorded $0.8 million and $0.9 million for the nine months ended September 30, 2021, and September 30, 2020, respectively, for expenses related to shut down and care and maintenance at our Velardeña Properties as the result of the suspension of mining and processing activities in November 2015. The reduced costs for 2021 are primarily the result of costs associated with activities at the Velardeña Properties being allocated to the Rodeo operation.

Administrative expense.  Administrative expenses totaled $3.5 million and $2.8 million for the nine months ended September 30, 2021, and September 30, 2020, respectively. Administrative expenses, including costs associated with being a public company, are incurred primarily by our corporate activities in support of the Velardeña Properties, El Quevar project and our exploration portfolio. The $3.5 million of administrative expenses we incurred during the nine months of 2021 is comprised of $1.6 million of employee compensation and directors’ fees, $1.0 million of professional fees and $0.9 million of insurance, rents, travel expenses, utilities and other office costs. The $2.8 million of administrative expenses we incurred during the nine months of 2020 is comprised of $0.9 million of employee compensation and directors’ fees, $1.0 million of professional fees and $0.9 million of insurance, rents, travel expenses, utilities and other office costs.  Compensation expense was higher in the 2021 period due primarily to cash bonuses paid to executives.

Stock based compensation. During the nine months ended September 30, 2021, we incurred approximately $1.5 million of expense related to stock-based compensation. During the nine months ended September 30, 2020, we incurred approximately $0.8 million of expense related to stock-based compensation.  Stock based compensation varies from period to period depending on the number and timing of shares granted, the type of grant, the market value of the shares on the date of grant and other variables. Stock based compensation was higher in the 2021 period due primarily to stock awards granted to executives and a consultant.

31

Reclamation and accretion expense. During each of the nine-month periods ended September 30, 2021, and September 30, 2020, we incurred approximately $0.2 million of reclamation expense related to the accretion of an asset retirement obligation at the Velardeña Properties.

Other operating income (expense), net. We recorded $0.5 million of other operating income for the nine months ended September 30, 2021, primarily related to the amortization of deferred income related to the option agreement for the sale of the Santa Maria property, as discussed above. We recorded $0.1 million of other operating expense for the nine months ended September 30, 2020, related to the write-off of a non-strategic exploration property in Mexico.

Depreciation, depletion and amortization. During the nine-month periods ended September 30, 2021, and September 30, 2020, we incurred depreciation, depletion and amortization expense of approximately $0.5 million and $0.8 million, respectively.

Interest and other expense, net. We recorded approximately $0.3 million of interest and other expense, net for the nine-month period ended September 30, 2021, primarily related to write-off of deferred costs related to the Lincoln Park Capital program. We recorded $0.1 million of interest and other expense, net for the nine months ended September 30, 2020, primarily related to interest accrued during the period on the Sentient loan and Autlán deposit.

Gain (Loss) on foreign currency. We recorded a $0.2 million foreign currency gain and a $0.1 million foreign currency loss for the nine months ended September 30, 2021, and September 30, 2020, respectively. Foreign currency gains and losses are primarily related to the effect of currency fluctuations on monetary transactions incurred by our foreign subsidiaries that are denominated in currencies other than US dollars.

Income taxes. We recorded a $203,000 tax expense for the nine months ended September 30, 2021 and $18,000 tax expense for the nine months ended September 30, 2020.

Liquidity and Capital Resources

At September 30, 2021, our aggregate cash and cash equivalents totaled $8.8 million, compared to the $9.7 million in similar assets held at December 31, 2020. The September 30, 2021 balance is due in part from the following expenditures and cash inflows for the nine months ended September 30, 2021.  Expenditures totaled $10.6 million from the following:

● $4.0 million for exploration expenditures at the Rodeo, Yoquivo and other properties;

● $1.2 million for capital expenditures primarily related to construction of the new regrind mill circuit related to the Rodeo operation;

● $0.8 million in care and maintenance costs at the Velardeña Properties;

● $0.2 million in exploration and evaluation activities, care and maintenance and property holding costs at the El Quevar project, net of reimbursements from Barrick;

● $3.5 million in general and administrative expenses; and

● $0.9 million related to a net working capital increase due primarily to an increase in inventories and value added tax receivables associated with the Rodeo operation, partially offset by an increase in accounts payable and other accrued liabilities, also related to the Rodeo operation.

The foregoing expenditures were offset by cash inflows of $9.7 million from the following:

● $6.9 million of net operating margin from the Rodeo operation (defined as revenue from the sale of metals less the cost of metals sold).

● $1.8 million, net of fees from the ATM Program (as further described above in Note 15); and

● $1.0 million from the exercise of warrants issued in prior offerings (as further described above in Note 15).

32

In addition to the $8.8 million cash balance at September 30, 2021, we expect to receive approximately $11.0 million to $12.0 million in net operating margin from the Rodeo Property (defined as revenue from the sale of metals less the cost of metals sold) during the twelve months ending September 30, 2022, assuming an average gold and silver price during that period of $1,800 and $25.00 oz respectively (our realized prices for the nine months ended September 30, 2021, as shown above, were $1,797 and $25.64 for gold and silver, respectively). Our forecasted cash inflows during the twelve months ending September 30, 2022 also now include the anticipated second installment of $1.5 million from the sale of the Santa Maria property to Fabled, scheduled to be paid in December 2021, as discussed above, as the Company believes the likelihood of receiving this installment has increased.

Our forecasted expenditures during the twelve months ending September 30, 2022, apart from Rodeo cost of metals sold, which is already included in our forecast of net operating margin, total approximately $10.0 million as follows:

● Approximately $4.9 million on exploration activities and property holding costs related to our portfolio of exploration properties located in Mexico, Argentina and Nevada, including project assessment and evaluation costs relating to additional exploration at Rodeo, Yoquivo, and other properties;

● Approximately $0.8 million at the Velardeña Properties for care and maintenance;

● Approximately $0.6 million at the El Quevar project to fund care and maintenance and property holding costs, net of reimbursement from Barrick; and

● Approximately $3.7 million on general and administrative costs.

Our forecasted cash resources of approximately $21.3 to $22.3 million, which include cash on hand at September 30, 2021, the forecasted net operating margin from the Rodeo Property, and the anticipated second installment of $1.5 million from the sale of the Santa Maria property to Fabled, are greater than our forecasted expenditures of approximately $10.0 million.  The actual net operating margin received from the Rodeo Property could be negatively impacted if further interruptions due to COVID-19 occur in Mexico.  The actual amount of cash receipts that we receive during the period from the Rodeo operation may also vary significantly from the amounts specified above due to, among other things: (i) unanticipated variations in grade, (ii) unexpected challenges associated with our proposed mining plan, (iii) decreases in commodity prices below those used in calculating the estimates shown above, (iv) variations in expected recoveries, (v) increases in operating costs above those used in calculating the estimates shown above, or (vi) interruptions in production at Rodeo.  In addition, the actual amount of cash that we receive from the anticipated second installment of $1.5 million from the sale of the Santa Maria property to Fabled is dependent on Fabled’s decision to pay the amount that is due to us under the terms of the Fabled Option Agreement on a timely basis. The actual amount of cash expenditures that we incur during the twelve-month period ending September 30, 2022 may vary significantly from the amounts specified above and will depend on a number of factors, including variations in the anticipated care and maintenance costs at the Velardeña Properties or at El Quevar, and costs for continued exploration, project assessment, and development at our other exploration properties.  Likewise, if cash expenditures are greater than anticipated or if cash receipts are less than anticipated, we may need to take certain actions to maintain sufficient cash balances over the next twelve months, including additional asset dispositions or raising additional equity capital through sales under the ATM Program or otherwise.

The condensed consolidated financial statements have been prepared on a going concern basis under which an entity is considered to be able to realize its assets and satisfy its liabilities in the normal course of business.  However, our continuing long-term operations may be dependent upon our ability to continue currently profitable operations and to secure sufficient funding, if needed, to generate future profitable operations.  The underlying value and recoverability of the amounts shown as property, plant and equipment in our condensed consolidated financial statements are dependent on our ability to continue to generate positive cash flows from operations and to continue to fund exploration and development activities that would lead to additional profitable mining and processing activities or to generate proceeds from the disposition of property, plant and equipment.  There can be no assurance that we will be successful in continuing to generate profitable mining and processing activities or to securing additional funding, if needed, to generate future profitable operations on terms acceptable to us or at all. We believe the cash on hand, anticipated positive net operating margins from the Rodeo operation, the potential use of the ATM Program, and the potential for additional asset dispositions make it probable that we will have sufficient cash to meet our financial obligations and continue our business strategy beyond one year from the filing of our condensed consolidated financial statements for the period ended September 30, 2021.

Recent Accounting Pronouncements

In December 2019, the FASB issued No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). The guidance removes certain exceptions to the general principles of ASC 740 and simplifies several other areas. ASU 2019-12 is effective for public business entities for annual reporting periods beginning after December 15, 2020, and interim periods within those reporting periods.  The Company has adopted ASU 2019-12 beginning in 2021.  One of the amendments within ASU 2019-12 eliminates a limitation on the amount of income tax benefit that can be recognized in an interim period when a year-to-date loss exceeds the anticipated loss for the year.  The Company has applied this guidance in the calculation of the tax benefit included in “Income taxes” in the Condensed Consolidated Statements of Operations.  The adoption of this guidance did not result in a material impact on our consolidated financial position or results of operations.

During the first quarter 2020, we adopted ASU No. 2016-13. ASU 2016-13 modifies the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the timelier recognition of losses. As our principle credit risk is related to its lease receivables, the adoption of this update did not result in a material impact on our consolidated financial position or results of operations.

On April 12, 2021, the SEC published a statement relating to accounting and reporting considerations for warrants issued by Special Purpose Acquisition Companies (SPACs). The SEC statement raised accounting and reporting considerations for all reporting entities that restrict the use of the exception noted above under ASC 815-40-25-7 thru 8 that allows for equity treatment, under certain conditions, for warrants that allow cash settlement in certain change of control transactions. The restriction put forth by the SEC would prevent equity treatment in cases where cash is received disproportionately between shareholders and warrant holders in such transactions.  All of the outstanding warrants granted by us are recorded in equity at September 30, 2021 and December 31, 2020 following the guidance established by ASC Topic 815-40.  Our warrants allow for the potential settlement in cash if certain extraordinary events are effected by us, including a 50% or greater change of control in our common stock.  Since those events have been deemed to be within our control, we continue to apply equity treatment for these warrants.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We invest substantially all of our excess cash in U.S. government and debt securities rated “investment grade” or better. The rates received on such investments may fluctuate with changes in economic conditions. Based on the average cash and investment balances outstanding during the first nine months of 2021, a 1% decrease in interest rates would have resulted in only a nominal reduction in interest income for the period.

Foreign Currency Exchange Risk

Although most of our expenditures are in U.S. dollars, certain purchases of labor, supplies and capital assets are denominated in other currencies, primarily in Mexico. As a result, currency exchange fluctuations may impact the costs of our exploration and mining activities. To reduce this risk, we maintain minimum cash balances in foreign currencies and complete most of our purchases in U.S. dollars.

35

Commodity Price Risk

We are primarily engaged in the exploration and mining of properties containing gold, silver, zinc, lead and other minerals. As a result, decreases in the price of any of these metals have the potential to negatively impact our ability to establish reserves and mine on our properties. We currently hold no commodity derivative positions.

Our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer) have evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of September 30, 2021, (the “Evaluation Date”). Based on such evaluation, such officers have concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer to allow timely decisions regarding required disclosure.

(b)  Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.     Legal Proceedings

During April 2021, we became aware of a lawsuit in Mexico against one of our 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 we have 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 our 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 our 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 our ability to operate the Rodeo mine, which is held through a different Mexico subsidiary, or continue with our evaluation plans for a potential Velardeña mine restart or move forward with any of our other exploration programs in Mexico.  Unifin is seeking recovery for as much as US$12.5 million.  We believe there is no basis for this claim and will defend ourselves if and when we are formally served with notice of the lawsuit.  As such, we have not accrued an amount for this matter in our Condensed Consolidated Balance Sheets or Statements of Operations as of September 30, 2021.

Item 1A. Risk Factors

The risk factors for the nine months ended September 30, 2021, are substantially the same as those set forth in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2020.

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, 2020 and filed with the SEC on February 18, 2021.

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 7), 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 our 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 that 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 company under SEC criteria since it has not yet demonstrated the existence of proven or probable mineral reserves, as defined by SEC Industry Guide 7, at any of its properties. Until such time, if ever, that the Company demonstrates the existence of proven or probable reserves pursuant to SEC Industry Guide 7, we expect to remain as an exploration stage company.

2. New Accounting Pronouncements

In December 2019, the FASB issued No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). The guidance removes certain exceptions to the general principles of ASC 740 and simplifies several other areas. ASU 2019-12 is effective for public business entities for annual reporting periods beginning after December 15, 2020, and interim periods within those reporting periods.  The Company has adopted ASU 2019-12 beginning in 2021.  One of the amendments within ASU 2019-12 eliminates a limitation on the amount of income tax benefit that can be recognized in an interim period when a year-to-date loss exceeds the anticipated loss for the year.  The Company has applied this guidance in the calculation of the tax benefit included in “Income taxes” in the Condensed

Consolidated Statements of Operations.  The adoption of this guidance did not result in a material impact on the Company’s consolidated financial position or results of operations.

During the first quarter 2020, the Company adopted ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 modifies the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. The adoption of this update did not result in a material impact on the Company’s consolidated financial position or results of operations.

On April 12, 2021, the SEC published a statement relating to accounting and reporting considerations for warrants issued by Special Purpose Acquisition Companies (SPACs). The SEC statement raised accounting and reporting considerations for all reporting entities that restrict the use of the exception under ASC 815-40-25-7 thru 8 that allows for equity treatment, under certain conditions, for warrants that allow cash settlement in certain change of control transactions. The restriction put forth by the SEC would prevent equity treatment in cases where cash is received disproportionately between shareholders and warrant holders in such transactions.  All of the outstanding warrants granted by the Company are recorded in equity at September 30, 2021 and December 31, 2020 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.

3.     Cash and Cash Equivalents and Short-term Investments

Of the $8.8 million reported as “Cash and cash equivalents” on the Condensed Consolidated Balance Sheets at September 30, 2021, 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 20.  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 September 30, 2021 and December 31, 2020:

			Estimated		Carrying

The short-term investments at September 30, 2021 and December 31, 2020 consist of 1,000,000 common shares of Fabled Silver Gold Corp., formerly known as Fabled Copper Corp. (“Fabled”), 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 7). The 1,000,000 common shares were issued to the Company as partial consideration per the terms of the option agreement.

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.

At September 30, 2021, the Company recorded a net value added tax (“VAT”) paid in Mexico of $1.1 million, related to the Velardeña Properties and the Rodeo operation, as a recoverable asset, which appears in “Value added tax receivable, net” on the Condensed Consolidated Balance Sheets.  Mexico law allows for certain VAT payments to be recovered through ongoing applications for refunds. During the third quarter ended September 30, 2021, the Company recovered approximately $1.5 million of the VAT receivable recorded at June 30, 2021.  The Company expects that the current

amounts will be recovered within a one-year period.  At September 30, 2021, the Company recorded approximately $0.4 million of VAT payable as a reduction to the VAT receivable in Mexico.

The Company has also paid VAT in Mexico as well as other countries, primarily related to exploration projects, which has been charged to expense as incurred because of the uncertainty of recoverability.

El Quevar Earn-In Agreement

On April 9, 2020, the Company and several of its directly and indirectly wholly-owned subsidiaries entered into the Earn-in Agreement with Barrick, pursuant to which Barrick has acquired an option (the “Option”) to earn a 70% interest in the Company’s El Quevar project located in the Salta Province of Argentina. Pursuant to the terms of the Earn-in Agreement, in order to earn an undivided 70% interest in the El Quevar project, Barrick must: (A) incur a total of $10 million in work expenditures over a total of eight years ($0.5 million per year in years one and two, $1 million per year in years three, four and five, and $2 million per year in years six, seven and eight); (B) deliver to the Company a National Instrument 43-101 compliant pre-feasibility study pursuant to the parameters set forth in the Earn-in Agreement; and (C) deliver a written notice to exercise the Option to the Company within the term of the Earn-in Agreement. Barrick may withdraw from the Earn-in Agreement at any time after spending a minimum of $1 million in work expenditures and upon providing 30 days’ notice to the Company. The Company will form a new entity (“NewCo”) that will hold the El Quevar properties.  Upon satisfaction of the Earn-in conditions and exercise of the Option, NewCo will be 70% owned by Barrick and 30% owned by the Company. Funding of NewCo will be based on Barrick’s and the Company’s respective ownership and industry standard dilution mechanisms will apply in the case of funding shortfalls by either shareholder.  As of September 30, 2021, Barrick had met the $1 million in work expenditures that would allow them to withdraw from the Earn-in Agreement.  

In connection with the Earn-in Agreement, the Company and Barrick also entered into a Subscription Agreement (the “Subscription Agreement”) dated as of April 9, 2020 pursuant to which Barrick purchased 4,719,207 shares of the Company’s common stock at a purchase price of $0.2119 per share in a private placement transaction (see Note 15).

Sale of Santa Maria Property

On July 14, 2020, the Company entered into a binding letter of intent (“Letter of Intent”) with Fabled for a potential transaction pursuant to which Fabled would acquire the Company’s option to earn a 100% interest in the Santa Maria mining claims located in Chihuahua, Mexico (the “Option”). On December 4, 2020, the Company entered into a definitive option agreement (“Option Agreement”) to sell its option to Fabled.  The period to exercise the Option (the “Exercise Period”) expires on December 4, 2022, unless extended by the parties under the terms of the Option Agreement. As consideration for the Option, Fabled (i) paid $500,000 in cash to the Company and issued to the Company 1,000,000 shares of Fabled’s common stock (the “Closing Consideration”); (ii) will pay $1,500,000 in cash to the Company on the one year anniversary date following the closing of the Option Agreement; (iii) will pay $2,000,000 in cash to the Company on the two year anniversary date following the closing of the Option Agreement; and (iv) upon exercise of the Option, will grant

the Company a 1% net smelter return royalty on the Maria, Martia III, Maria II Frac. I, Santa Maria and Punto Com concessions (the “Concessions”).  Pursuant to the Option Agreement, during the Exercise Period, Fabled is obligated to pay to each of the owners of the Concessions any remaining required payments due to the owners pursuant to the various underlying option agreements between the owners and the Company, and to make all payments and perform all other requirements needed to maintain the Concessions in good standing.  As of September 30, 2021, there was approximately $0.2 million of concession payments remaining to be paid by Fabled over the next approximately one year.  Should Fabled not complete its obligations described above, the Santa Maria mining claims will revert to the Company and the Company will be entitled to keep any payments made by Fabled under the terms of the Option Agreement.  

The Company recorded the $0.5 million received from Fabled upon execution of the agreement to Deferred revenue on the accompanying Condensed Consolidated Balance Sheets and is amortizing the amount to income over a one-year period. At September 30, 2021, there is a remaining unamortized balance of approximately $0.1 million.

The deferred offering costs at September 30, 2021 are associated with the ATM Agreement (see Note 15).  The deferred offering costs at December 31, 2020 were associated with the ATM Agreement and the Commitment Purchase Agreement (see Note 15). The Commitment Purchase Agreement expired during June 2021, and as of September 30, 2021 the Company had written off the remaining balance of $353,000 of deferred LPC Program costs to “Interest and Other Expense” on the Condensed Consolidated Statement of Operations.

The right of use assets at September 30, 2021 include approximately $0.4 million related to certain office leases and $0.3 million related to a mining equipment lease at our Rodeo Property.  The right of use assets at December 31, 2020 include approximately $0.5 million related to certain office leases and $0.5 million related to a mining equipment lease at our Rodeo Property.  

The Company took possession of new office space and began a new long-term lease for its principal headquarters office with an effective commencement date of June 1, 2019. The new office lease will expire five years and eight full calendar months following the commencement date. There are no options to extend the lease beyond the stated term. The Company recorded a right of use asset of approximately $465,000 and a lease liability of approximately $450,000 in the second quarter of 2019 based on the net present value of the future lease payments discounted at 9.5%, which represents the Company’s incremental borrowing rate for purposes of applying the guidance of Topic 842. As required, the Company will recognize a single lease cost on a straight-line basis.

The Company also has long-term office leases in Mexico and Argentina that expired in 2019 and recorded a combined lease liability of approximately $45,000 and combined right of use asset of approximately $45,000 relating to both of those leases at January 1, 2019. In November 2019, the Company renewed its Mexican office lease for four years and recorded a right of use asset and lease liability of approximately $174,000. In December 2019, the Company also renewed its Argentina office lease for two years and recorded a right of use asset and lease liability of approximately $18,000.

In December 2020, the Company’s wholly-owned subsidiary, Minera de Cordilleras S. de R.L. de C.V., entered into an agreement with Triturados del Guadiana, S.A de C.V. (“Trigusa”), whereby Trigusa will carry out mining activities at the Rodeo Property.  Per the terms of the mining agreement, Trigusa will provide services for the 27-month period beginning in December 2020 and ending March 31, 2023, with the potential for an extension of time upon mutual agreement of both parties. The Company has determined that the mining agreement contains an embedded lease, relating to the mining equipment provided by Trigusa, per the guidance of ASU 2016-02 and Topic 842. The Company did not elect the practical expedient permitting the combination of lease and non-lease components of the mining agreement.  The

Company recorded a right of use asset and a lease liability of approximately $420,000 based on the net present value of the future lease payments discounted at 7.0%, which represents the Company’s incremental borrowing rate.

The lease liabilities noted above have been included in “Other liabilities”, short term and long term (Note 11), in the Company’s Consolidated Balance Sheets at September 30, 2021 and December 31, 2020.

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.

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 nine months of 2021, the Company recognized approximately $196,000 of accretion expense.

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:  Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2:  Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

Level 3:  Unobservable inputs due to the fact that there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

The following table summarizes the Company’s financial assets and liabilities at fair value on a recurring basis at September 30, 2021 and December 31, 2020, by respective level of the fair value hierarchy:

	Level 1		Level 2		Level 3		Total

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 nine months ended September 30, 2021, the Company recognized $203,000 of income tax expense, of which $162,000 represented a current tax expense and $41,000 was a deferred tax expense. Of the total amount for the nine months ended September 30, 2020 the Company recognized $18,000 of income tax expense, all of which was a current 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 September 30, 2021, the Company had no net deferred tax assets or net deferred tax liabilities on the Condensed Consolidated Balance Sheets, and as of December 31, 2020, the Company had no net deferred tax assets or net deferred tax liabilities reported on its balance sheet.

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 September 30, 2021 or December 31, 2020.

Public offering

On July 21, 2020, the Company entered into an Amended and Restated Underwriting Agreement (the “Underwriting Agreement”) with H.C. Wainwright & Co., LLC as representative of the underwriters named therein (the “Underwriters”), providing for the issuance and sale by the Company in a firm commitment offering (the “Offering”) of 17,857,143 shares of common stock at a price to the public of $0.42 per share (the “Offering Shares”). In addition, the Company granted the Underwriters an option to purchase, at the public offering price per share of common stock, up to an additional 2,678,571 shares of common stock, exercisable for 30 days from the date of the Underwriting Agreement (the “Option Shares”).  The Offering Shares and Option Shares were registered pursuant to the Company’s registration statement on Form S-3 (File No. 333-220461), and a prospectus supplement thereto filed with the Securities and Exchange Commission.  On July 24, 2020, the Underwriters acquired the Offering Shares and the full amount of the Option Shares from the Company.  After the underwriting discount of 6% and total offering expenses of approximately $155,000 the Company received net proceeds of approximately $8.0 million from the sale of the Offering Shares and the Option Shares.  

Subscription agreement

In connection with the Earn-in Agreement (see Note 7), the Company and Barrick entered into the Subscription Agreement dated as of April 9, 2020 pursuant to which Barrick purchased 4,719,207 shares of the Company’s common stock at a purchase price of $0.2119 per share in a private placement transaction. The shares were offered and sold without registration under the Securities Act of 1933, as amended (the “Act”) in reliance on the exemptions provided by Section 4(a)(2) of the Act and/or Regulation D promulgated thereunder. The net proceeds of the Subscription Agreement of approximately $0.9 million were recorded in equity.

Offering and private placement

On April 20, 2020, the Company entered into a securities purchase agreement with certain institutional investors providing for the issuance and sale of 15,000,000 shares of the Company’s common stock at a price of $0.20 per share, and in a concurrent private placement transaction, the issuance of an aggregate of 11,250,000 warrants, ultimately consisting of 7,500,000 series A warrants and 3,750,000 series B warrants (collectively, the “Warrants”), to purchase up to 11,250,000 shares of our common stock at an exercise price of $0.30 per share, for aggregate gross proceeds of $3.0 million (the “Offering”). Each Warrant is exercisable six months from the date of issuance on April 22, 2020 and has a term expiring five years after such initial exercise date. The Warrants contain so-called full-ratchet anti-dilution provisions which may be triggered upon any future issuance by the Company of shares of its common stock or common stock equivalents at a per share price below the then-exercise price of the Warrant, subject to certain exceptions; provided, however, that with respect to the Series B warrants, the adjusted exercise price will not be less than $0.26.

The net proceeds of the Offering were recorded in equity. Total costs for the Offering were approximately $334,000, including listing fees, legal and other costs, and the placement agent fee of six percent of aggregate gross proceeds; however, a reduced fee was accepted with respect to one investor. All such costs were recorded as a reduction to “Additional paid in capital” on the Condensed Consolidated Balance Sheets.  Using the Black Scholes model, and assuming no triggering events take place to reduce the exercise price of the Warrants, the fair value of the combined Series A and Series B warrants issued was approximately $1.9 million on April 22, 2020, the date of issuance of the Warrants. The Black Scholes inputs included the closing stock price on April 22, 2020 (the date of issuance of the Warrants) of $0.24, the exercise price and exercise period of the Warrants, the Company’s applicable volatility rate for the period of the Warrants of 95%, and the applicable risk-free rate of 0.41%.

Commitment purchase agreement

On May 9, 2018, the Company entered into a commitment purchase agreement (the “Commitment Purchase Agreement”) with 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.

During the nine months ended September 30, 2021, the Company did not sell any shares of common stock to LPC under the Commitment Purchase Agreement. 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” on the Condensed Consolidated Statement of Operations during the three-month period ended March 31, 2021.  

During the nine months ended September 30, 2020, the Company sold 900,000 shares of common stock to LPC under the Commitment Purchase Agreement at an average sales price per share of approximately $0.27, resulting in net proceeds of approximately $216,000.  In addition, approximately $24,000 of Commitment Purchase Agreement costs were amortized, resulting in a remaining balance of $353,000 of deferred LPC Program costs, recorded in “Other long-term assets” on the Condensed Consolidated Balance Sheets as of September 30, 2020.

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 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.  At September 30, 2021 there was a remaining balance of $71,000 of deferred ATM Program costs, recorded in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheets as of September 30, 2021.

During the first nine months of 2020, the Company sold an aggregate of 823,452 shares of common stock under the ATM Agreement at an average price of $0.28 per share of common stock for net proceeds of approximately $223,000.  In addition, approximately $8,000 of deferred ATM Program costs were amortized, resulting in a remaining balance of $129,000 of deferred ATM Program costs, recorded in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheets as of September 30, 2020.

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 September 30, 2021 and the changes during the nine months then ended:

		Weighted
		Average Grant
		Date Fair
	Number of	Value Per

Restrictions lifted during the period	(265,668)		0.47
Forfeited during the period	—		—
Outstanding September 30, 2021	293,334	$	0.61

For the nine months ended September 30, 2021, the Company recognized approximately $139,000 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 $98,000 over the next 21 months. During the nine months ended September 30, 2021, 335,000 shares were granted to nine employees, with one-third of the grants vesting on the grant date and the remaining shares vesting equally on the first and second anniversaries of the grant date. Also during the period, restrictions were lifted on the normal vesting of 154,002 shares granted to six employees in prior years.

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 September 30, 2021 and the changes during the nine months then ended:

		Weighted

Outstanding September 30, 2021	3,910,038	$	0.70

For the nine months ended September 30, 2021, the Company recognized approximately $162,000 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 $127,000 over the next 9 months. During the nine months ended September 30, 2021, 50,000 RSUs were granted to each of the six board members for a total of 300,000 RSUs.

During the nine months ended September 30, 2021, the Company granted a consultant 100,000 RSUs and recognized $67,000 of stock compensation expense. 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 September 30, 2021 and December 31, 2020.

During the nine-month period ended September 30, 2021, the Company granted 1,605,000 KELTIP Units to two officers of the Company and recognized approximately $1.0 million of stock compensation expense related to the grants.  During the nine-month period ended September 30, 2020, the Company granted 1,400,000 KELTIP Units to two officers of the Company and recognized approximately $0.5 million of stock compensation expense related to the grants. There were 5,330,000 and 3,725,000 KELTIP Units outstanding at September 30, 2021 and December 31, 2020, respectively.

The warrants relate to prior registered offerings and private placements of the Company’s stock.

As discussed above under “Equity – Offering and private placement”, on April 20, 2020, the Company entered into a securities purchase agreement with certain institutional investors providing for the issuance and sale of 15,000,000 shares of the Company’s common stock and in a concurrent private placement transaction, the issuance of an aggregate of 11,250,000 warrants, ultimately consisting of 7,500,000 series A warrants and 3,750,000 series B warrants.  During the year ended December 31, 2020, and the nine months ended September 30, 2021, 6,400,000 series A warrants and 3,500,000 series B warrants were exercised leaving a balance of 1,100,000 and 250,000 series A and series B warrants outstanding, respectively as of September 30, 2021.

On July 17, 2019, the Company issued 8,653,846 registered shares of common stock in a registered direct offering. In connection with the offering, each investor received an unregistered Series A warrant to purchase a share of common stock for each share of common stock purchased. Each Series A warrant is exercisable six months from the date of issuance and has a term expiring in January 2025.  During the nine months ended September 30, 2021, 200,000 series A warrants were exercised, leaving a balance of 8,453,846 series A warrants outstanding.

In May 2016, the Company issued 8.0 million registered shares of common stock at a purchase price of $0.50 per share in a registered direct offering resulting in gross proceeds of $4.0 million. In connection with the offering, each investor received an unregistered warrant to purchase three-quarters of a share of common stock for each share of common stock purchased. The resulting 6,000,000 warrant shares have an exercise price of $0.75 per share, became exercisable on November 7, 2016 and were exercisable until November 6, 2021, five years from the initial exercise date. In connection with a July 2019 registered direct offering, the Company agreed to exchange, on a one-for-one basis, 4,500,000 of the May 2016 warrants for Series B warrants to purchase 4,500,000 shares of common stock at an exercise price of $0.35 per share. Each Series B warrant is exercisable six months from the date of issuance and has a term expiring in May 2022.  During the nine months ended September 30, 2021, 1,500,000 series B warrants were exercised leaving a balance of 3,000,000 series B warrants and 1,500,000 of the original July 2016 warrants outstanding, respectively.

All outstanding warrants are recorded in equity at September 30, 2021 and December 31, 2020 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.

16. Sale of Metals and Related Costs

During the nine months ended September 30, 2021, the Company sold gold and silver contained in doré bars related to the Rodeo operation and recorded revenue of approximately $16.1 million and related costs of approximately $9.2 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 10-12 days after the product is shipped and customary sales documents are completed.  A final payment is made within 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.

Costs related to the sale of metals products include direct and indirect costs incurred to mine, process and market the products.  

During the nine months ended September 30, 2020 the Company did not sell any doré products or incur any related costs.

For the nine months ended September 30, 2020, the Company recorded revenue of approximately $4.6 million and related costs of approximately $1.6 million associated with the lease of the Velardeña Properties oxide plant. The Company recognizes oxide plant lease fees and reimbursements for labor, utility and other costs as “Revenue: Oxide plant lease” in the Condensed Consolidated Statements of Operations following the guidance of ASC 842.  ASC 842 supports recording as gross revenue the reimbursement of expenses incurred directly by the Company in performing its obligations under the lease in situations where the entity has control over the specific goods or services transferred to a customer as a principal versus as an agent. The actual costs incurred for reimbursed direct labor and utility costs are reported as “Oxide plant lease costs” in the Condensed Consolidated Statements of Operations. The Company recognizes lease fees during the period the fees are earned per the terms of the lease.

On July 7, 2020, the Company received notification from Hecla terminating the Lease Agreement pursuant to the Third Amendment, effective November 30, 2020. Therefore, during the nine months ended September 30, 2021 the Company did not record any income or costs associated with the lease of the oxide plant to Hecla.

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 September 30, 2021.

On April 23, 2021, a new labor law was made official in Mexico that will impact companies that utilize subcontractor structures, effective beginning August 1, 2021.  The Company utilizes subcontractor structures in Mexico, as is common practice among companies in the mining and other industries in Mexico.  The law will disallow a deduction in computing income taxes for labor outsourcing costs, unless the arrangement falls within certain narrowly defined exceptions.  The new law does provide for annual caps on the amount of employee profit sharing a company would be required to pay, which is designed to even out the profit sharing liability over several years.  As of September 30, 2021, the Company has reorganized the functions performed by its various Mexican subsidiaries to comply with the new law.  The Company estimates its profit sharing liability in Mexico will increase for the full year 2021 as a result of the new law taking effect and the completion of the Company’s reorganization process and has accrued approximately $136,000 for such amount, included in “Accounts payable and other accrued liabilities” in the Company’s Consolidated Balance Sheets at September 30, 2021.  

At December 31, 2020, the Company had no gain or loss contingencies.  The Company has certain purchase and lease commitments as set forth in the Company’s Form 10-K for the year ended December 31, 2020.

22.     Related Party Transactions

The following sets forth information regarding transactions between the Company (and its subsidiaries) and its officers, directors and significant stockholders.

Administrative Services, Lease of Equipment:

Beginning in August 2016, the Company began providing limited accounting and other administrative services to Minera Indé, an indirect subsidiary of Sentient.  At September 30, 2021, Sentient, through the Sentient executive funds, holds approximately 23% of the Company’s 162.5 million shares of issued and outstanding common stock.  The administrative services are provided locally in Mexico by the administrative staff in the Company’s Mexico office. The Company charges Minera Indé $15,000 per month for the services, which provides reimbursement to the Company for its costs incurred plus a small profit margin. The Company also leases, from time to time, certain nonessential mining equipment to Minera Indé. Amounts received under the arrangement reduce costs incurred for exploration.  The Company’s Board of Directors and Audit Committee approved the agreement. For the nine months ended September 30, 2021 and 2020, the Company charged Minera Indé approximately $204,000 for services and the use of equipment, offsetting costs that are recorded in “Exploration expense” in the Condensed Consolidated Statements of Operations.

Debt – Related Party

On March 30, 2020, the Company entered into a short-term loan agreement with Sentient whereby the Company received an unsecured loan in the amount of $1,000,000. The Sentient Loan had an interest rate of 10% per annum and was due in full, together with accrued interest and any other amount outstanding under the loan agreement, on December 31, 2020. During August 2020, the Company paid in full the principal amount of the loan plus accrued interest. See Note 10 for a full description of the loan.
