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” “we” “our” or “us”), 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. Interim results are not necessarily indicative of results for a full year; accordingly, these interim condensed consolidated 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, 2025, filed with the SEC on April 1, 2026 (the “2025 Annual Report”).

The Company is considered an exploration stage issuer under the criteria set forth by the SEC under Subpart 1300 of Regulation S-K (“S-K 1300”) as the Company has not yet demonstrated the existence of mineral reserves at any of the Company’s properties. As a result, and in accordance with GAAP for exploration stage companies, all expenditures for exploration and evaluation of the Company’s properties are expensed as incurred. As such, the Company’s financial statements may not be comparable to the financial statements of mining companies that have proven and probable mineral reserves. Such companies would typically capitalize certain development costs including infrastructure development and mining activities to access the ore. The capitalized costs would be amortized on a units-of-production basis as reserves are mined. The amortized costs are typically allocated to inventory and eventually to cost of sales as the inventories are sold. The Company cannot be certain that any deposits at any of its properties will ever be confirmed or converted into S-K 1300 compliant “reserves.”

Operating Segments and Related Disclosures

We manage our company as one reportable operating segment, exploration activities. The segment information aligns with how the Company’s Chief Operating Decision Maker (“CODM”) reviews and manages our business. The Company’s CODM is the Company’s Chief Executive Officer. Financial information and annual exploration plans and forecasts are prepared and reviewed by the CODM at a consolidated level. The CODM assesses performance for the exploration activities segment and decides how to better allocate resources based on consolidated net income or loss that is reported on the interim Condensed Consolidated Statements of Operations. The Company’s objective in making resource allocation decisions is to optimize the consolidated financial results. The accounting policies of our exploration activities segment are the same as those described in the summary of significant accounting policies. Refer to Note 3 to the financial statements included in the Company’s 2025 Annual Report for a description of our Significant Accounting Policies.

2. Liquidity, Capital Resources and Going Concern

As at June 30, 2026, we did not have sufficient resources to meet our expected cash needs for a period of twelve months beyond the filing date of this 2026 Quarterly Report on Form 10-Q. At June 30, 2026, we had current assets of approximately $2.6 million, including cash and cash equivalents of approximately $2.5 million. On the same date, we had accounts payable and other current liabilities of approximately $1.0 million.

The Company’s only near-term opportunity to generate cash flow to meet its expected cash requirements is from asset sales, equity, or other external financing. The Company is evaluating and pursuing alternatives, including the potential sale of the Company, seeking buyers or partners for the Company’s other assets or obtaining equity or other external financing. During the six months ended June 30, 2026, the Company (a) completed the sale of all issued and outstanding shares of Minera William, S.A. de C.V. to Streamline Metals Capital Ltd. (“Streamline”) and Horizon Silver Resources Ltd. (“Horizon”) for aggregate cash consideration of $1.2 million, and (b) completed a private placement of 3,740,000 shares of common stock to Streamline for aggregate gross proceeds of approximately $856,463 (see Notes 3 and 10). These transactions improved the Company’s cash position.

These interim 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, as noted above, our continuing long-term operations will be dependent upon our ability to secure sufficient funding to generate future profitable operations. The underlying value and recoverability of the amounts shown as property, plant and equipment in our consolidated financial statements are dependent on our ability to generate positive cash flows from operations and to fund general administrative, and exploration activities that would lead to additional profitable mining and processing activities or to generate proceeds from the disposition of property, plant and equipment.

Based on the Company’s cash-flow needs and taking into account the proceeds of the sale of Minera William and the May 2026 private placement, the Company expects its cash resources to fund operations into early to mid-2027. Notwithstanding the improved near-term liquidity resulting from these transactions, the Company has no revenue-generating operations and will require additional financing or asset monetization to sustain operations beyond the current forecast horizon. These conditions continue to raise substantial doubt about the Company’s ability to continue as a going concern for the twelve months following the issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

3. Assets Held for Sale and Discontinued Operations

The following tables present the results and financial position of the Company’s discontinued operations for the periods presented. The Company’s Mexico and Argentina operations were substantially concluded during 2024 and 2025, including the Velardeña Properties, Silex Argentina (El Quevar), Yoquivo Project, and related Mexican subsidiaries. For information regarding the individual transactions, refer to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, and prior quarterly reports filed with the SEC.

On May 14, 2026, the Company, through its subsidiaries ECU Silver Mining Inc. and Golden Minerals Services Corp., completed the sale of all of the issued and outstanding shares of Minera William, S.A. de C.V. (“Minera William”) to Streamline and Horizon for aggregate cash consideration of $1.2 million. Minera William represented the residual component of the Company’s Mexican operations, which were classified as discontinued operations. The Company recognized a gain on disposal of approximately $1.1 million.

The following table summarizes the major line items for our Mexico operations, both during the current and the comparative periods, that are included in Income (loss) from discontinued operations, net of taxes in the interim Condensed Consolidated Statements of Operations:

4. New and Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which requires disaggregated disclosure of certain costs and expenses. As clarified by ASU 2025-01, ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity. The ASU is effective for annual periods beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact of adopting the ASU on its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which introduces a practical expedient allowing entities to assume that current conditions will not change when estimating expected credit losses on certain current assets. The ASU became effective for annual periods beginning after December 15, 2025. The Company adopted ASU 2025-05 effective January 1, 2026. The adoption did not have a material impact on the Company’s consolidated financial statements.

5. Prepaid Expenses and Other Assets

	June 30,		December 31,
	2026		2025

Recoupable deposits and other		49		49
	$	177	$	107

During the six months ended June 30, 2026, the Company financed its annual insurance premiums through a commercial premium finance arrangement. As of June 30, 2026, prepaid insurance and a related insurance financing liability of approximately $124,000 and $106,000, respectively, are included in prepaid expenses and other assets and in accounts payable and other accrued liabilities.

6. Property, Plant and Equipment, Net

	June 30,		December 31,
	2026		2025
	(in thousands)
Accounts payable and accruals (Note 12)	$	713	$	1,058
Accrued employee compensation and benefits		313		306
	$	1,026	$	1,364

8. Fair Value Measurements

Financial assets and liabilities and nonfinancial assets and liabilities are measured at fair value on a recurring basis under a framework of a fair value hierarchy that 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 Topic 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 that estimate what market participants would use in pricing the asset or liability.

The following table summarizes the Company’s financial assets and liabilities measured on a recurring basis at fair value by respective level of the fair value hierarchy:

	Level 1		Level 2		Level 3		Total
	(in thousands)
At June 30, 2026
Assets:
Cash and cash equivalents	$	2,454	$	—	$	—	$	2,454
	$	2,454	$	—	$	—	$	2,454

At December 31, 2025
Assets:
Cash and cash equivalents	$	1,339	$	—	$	—	$	1,339
	$	1,339	$	—	$	—	$	1,339

At June 30, 2026 and December 31, 2025, the Company did not have any financial assets or liabilities classified within Level 2 or Level 3 of the fair value hierarchy.

9. Income Taxes

The Company accounts for income taxes in accordance with the provisions of ASC Topic 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. For the three and six months ended June 30, 2026 and 2025, the Company recorded zero income 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 interim Condensed Consolidated Balance Sheets. As of June 30, 2026 and December 31, 2025, the Company had no deferred tax assets and no deferred tax liability on the interim Condensed Consolidated Balance Sheets due to a valuation allowance offsetting the net deferred tax assets of the Company.

The Company, a Delaware corporation, and its subsidiaries file tax returns in the United States and in various foreign jurisdictions. The tax rules and regulations in these countries are highly complex and subject to interpretation. The Company’s income tax returns are subject to examination by the relevant taxing authorities and in connection with such examinations, disputes can arise with the taxing authorities over the interpretation or application of certain tax rules within the country involved. In accordance with ASC 740, the Company identifies and evaluates uncertain tax positions and recognizes the impact of uncertain tax positions for which there is less than a more-likely-than-not probability of the position being upheld upon review by the relevant taxing authority. Such positions are deemed to be “unrecognized tax benefits,” which require additional disclosure and recognition of a liability within the financial statements. The Company had no unrecognized tax benefits at June 30, 2026 and December 31, 2025.

10. Equity

Private Placement

On May 22, 2026, the Company completed a private placement of 3,740,000 shares of its common stock at a price of $0.2290 per share to Streamline, for aggregate gross proceeds of approximately $856,463. Net proceeds after share-issuance costs of approximately $803,744 (gross proceeds of $856,463 less share-issuance costs of $52,719, pertaining to professional and regulatory fees) were recorded as an increase to common stock of $37,400 and additional paid-in capital of $766,344. Share-issuance costs totaled approximately $52,719, of which $7,609 was paid in cash during the period and the remaining $45,110 was unpaid at June 30, 2026 and included in accounts payable and other accrued liabilities.

On February 26, 2026, the Company granted 200,000 RSUs to the Company’s CFO under the equity incentive plan. The RSUs vest in two equal installments, with 50% vesting on the first anniversary of the grant date and the remaining 50% vesting on the second anniversary of the grant date, subject to continued service with the Company.

As of June 30, 2026, 2,670,079 restricted stock units were outstanding, comprising 600,000 nonvested units and 2,070,079 units that have vested but for which the underlying common shares have not yet been issued. Vested restricted stock units are settled in common shares upon the holder’s separation from service or a change of control and remain outstanding until settled.

As of June 30, 2026, total unrecognized compensation cost related to nonvested restricted stock units was $121,000, which is expected to be recognized over a weighted-average period of 1.1 years.

		7,427,587

All outstanding common stock warrants are recorded in equity at June 30, 2026 and December 31, 2025, following the guidance established by ASC Topic 815-40. The Company’s common stock warrants allow for 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 common stock warrants.

11. Commitments and Contingencies

Previously disclosed claims related to the Company’s former operations in Mexico and prior employee and supplier claims have been fully resolved. For information regarding those claims and the Unifin Lawsuit, where the Company does not believe that any future liability would arise, see Item 3, Legal Proceedings, in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Mexican Mining Concession

In July 2025, the Company was notified by the Mexican Mining Registry of an outstanding balance of approximately $403,000 in fees, penalties, and late fees related to the Rucio mining concession, originally requested by Minera de Cordilleras, a subsidiary sold earlier in 2025. Under the terms of that sale, the Company would be responsible for this claim. The Rucio concession was originally requested in 2011 by a former manager of Minera de Cordilleras, was not issued until 2018, and the Company was never notified of its issuance or any associated payment obligations. The Company elected not to make payment pending further investigation, and the concession has since been cancelled by the Mining Registry. No enforcement action has been filed. The Company has initiated a concession annulment action to challenge the validity of the claim. As of June 30, 2026, no provision has been recorded as management believes that the outcome of this matter is uncertain.

Argentina Labor Claims

During 2025, the Company received three labor claims against its Argentina subsidiary from former employees seeking compensation. One of the labor claims has placed a lien on the Company’s Desierto concessions. As of June 30, 2026, the Company has accrued $250,000 for these matters, representing management’s best estimate of a probable loss. The Company intends to vigorously defend these claims.

As a result of the Company’s reduced or ceased operations in Argentina, the Company has been and may in the future be exposed to claims from former employees, labor unions, suppliers, consultants or contractors and tax and environmental claims, which may individually or in the aggregate be material.

Guarantee — Sale of Minera William

In connection with the May 2026 sale of Minera William, S.A. de C.V., the Company, as guarantor, guaranteed the obligations of ECU Silver Mining Inc. and Golden Minerals Services Corp. to Streamline and Horizon under the Share Purchase Agreement. The Company’s aggregate liability under the guarantee is limited to the $1,200,000 purchase price (with breaches of non-fundamental representations and warranties capped at $600,000), and the underlying representations, warranties and covenants survive for 24 months from closing, through May 14, 2028. The Company has assessed the guarantee under ASC 460 and ASC 450 and concluded that the fair value of the stand-ready obligation is immaterial and that a loss is not probable; accordingly, no liability has been recognized. The Company reassesses this conclusion at each reporting date.

12. Related Party Transactions

Accounting and Financial Reporting Services

Since June 1, 2025, the Company has outsourced its Chief Financial Officer function, together with certain other accounting functions, to Avisar Everyday Solutions Ltd. (“Avisar”), of which the Company’s Chief Financial Officer is a director, officer and principal shareholder. Amounts incurred for these services, which include the Chief Financial Officer function with no separate payment made to the Chief Financial Officer, were $62,887 for the six months ended June 30, 2026 and $16,109 for the comparable 2025 period (approximately one month, following commencement of the arrangement on June 1, 2025). As of June 30, 2026, $9,864 was owing to Avisar (December 31, 2025: $13,237).

Directors Compensation

As of June 30, 2026, amounts owing to directors for fees and expense reimbursements from prior years total $211,367 and are included in accounts payable and other accrued liabilities on the Condensed Consolidated Balance Sheet (December 31, 2025: $211,367). Since December 2024, the directors have continued to serve without cash compensation in order to preserve the Company’s liquidity, and no director fees were accrued during the six months ended June 30, 2026.

Streamline Metals Capital Ltd.

In May 2026, Streamline acquired all of the issued and outstanding shares of Minera William (jointly with Horizon; see Note 3) and separately subscribed for 3,740,000 shares of the Company’s common stock in a private placement (see Notes 3 and 10). As a result of the private placement, Streamline holds approximately 19.8% of the Company’s outstanding common stock, has the right to nominate a director to the Company’s board of directors, and is considered a related party. These transactions are described in the notes referenced above.

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. We are an exploration company holding or controlling majority interests in the Desierto and Sarita Este concessions, adjoining gold-silver-copper exploration projects located in northwest Salta Province, Argentina, and have earned a 60% interest in Sand Canyon, an exploration-stage gold-silver project in northwestern Nevada. Following the completion of the sale of Minera William in May 2026, the Company has completed its exit from Mexico, and its remaining focus is on advancing exploration at the Sarita Este/Desierto project in Argentina and the Sand Canyon project in Nevada, together with its corporate activities and the review of additional exploration opportunities, primarily in South America.

During 2024 and 2025, the Company substantially divested its operations in Mexico and Argentina, including the Velardeña Properties, the El Quevar silver project, the Yoquivo exploration property, and several Mexican subsidiaries. On May 14, 2026, the Company completed the sale of its remaining Mexican subsidiary, Minera William, S.A. de C.V., for total proceeds of $1.2 million; the assets of Minera William included net operating losses, a Capital Contribution Account (“CUCA”), the Par de Tres 2 mining concession, and the San Diego royalty. Because we have divested our mining operations, our near-term liquidity is principally dependent on proceeds from asset sales and equity financing, as further described under “Item 1. Financial Statements—Note 2. Liquidity, Capital Resources and Going Concern.”

2026 Highlights

During the three and six months ended June 30, 2026, other than the completed sale of Minera William, the Company had no new exploration activity or transactions of significance. The Company continued to focus on preserving cash resources while managing its exploration portfolio and evaluating strategic alternatives.

Sarita Este / Desierto Project

The Desierto project is located in the Puna geological region of Salta Province, Argentina. The Company controls 67% of the Desierto Project and continued its efforts to complete joint venture documentation with Cascadero Copper Corporation during the six months ended June 30, 2026. Following completion of the joint venture agreement, the Company anticipates initiating a Phase I drill program designed to test extensions of gold mineralization from the adjacent Sarita Este property. The timing of any drilling program depends on completing joint venture agreements and securing sufficient funding.

Sand Canyon Project

In January 2025, the Company exercised its option to earn a 60% interest in the Sand Canyon project in Humboldt County, Nevada. The parties are finalizing joint venture documentation. During the six months ended June 30, 2026, no drilling was planned; the Company continued to review historical exploration data to inform future exploration plans.

Financial Results of Operations

For the results of operations discussed below, we compare the results of operations for the three and six months ended June 30, 2026, to the results of operations for the three and six months ended June 30, 2025.

Exploration expense. Our exploration expense, including property holding costs and allocated administrative expenses, totaled $27 thousand and $81 thousand for the three months ended June 30, 2026 and 2025, respectively, and $86 thousand and $152 thousand for the six months ended June 30, 2026 and 2025, respectively, and were lower than in the comparable prior-year periods, reflecting a reduced level of exploration and property-holding activity, primarily as a result of holding fewer properties following the disposition of the Company’s Mexican operations in late 2025.

Administrative expense. Administrative expenses totaled $345 thousand for the three months ended June 30, 2026, compared to $748 thousand for the three months ended June 30, 2025, and $834 thousand for the six months ended June 30, 2026, compared to $1,463 thousand for the six months ended June 30, 2025. Administrative expenses, including costs associated with being a public company, are incurred primarily by our corporate activities in support of our exploration portfolio and consist principally of professional fees, together with ongoing accounting and tax fees; investor-relations,

transfer-agent, listing and regulatory fees, including annual-meeting and proxy costs; insurance; and salaries and benefits. The decrease compared with the prior-year periods primarily reflects lower professional and corporate costs, consistent with the reduced scale of the Company’s activities following the disposition and wind-down of its Mexican operations.

Stock-based compensation. Stock-based compensation expense was $72 thousand for the three months ended June 30, 2026 and $145 thousand for the six months ended June 30, 2026. Stock-based compensation varies from period to period depending on the number and timing of equity instruments granted, the type of grant, the market value of the shares on the date of grant and other variables.

Interest and other income (expense), net. Interest and other income, net, was $6 thousand and $52 thousand for the three months ended June 30, 2026 and 2025, respectively, and $11 thousand and $78 thousand for the six months ended June 30, 2026 and 2025, respectively. The decrease from the prior-year periods primarily reflects lower interest income earned on lower average cash balances.

Income Taxes. We recorded $nil income tax expense for the three and six months ended June 30, 2026 and 2025.

Income (loss) from discontinued operations, net of taxes. Income (loss) from discontinued operations, net of taxes, was $1,128 thousand and $83 thousand for the three months ended June 30, 2026 and 2025, respectively, and $1,142 thousand and $(319) thousand for the six months ended June 30, 2026 and 2025, respectively. In the current year, the Company received approximately $1.2 million on the sale of Minera William; in the prior year, it received approximately $0.6 million on the sale of Minera de Cordilleras. In each period, the remaining amounts consist principally of subsidiary holding costs, which were higher in the prior year owing to the larger number of subsidiaries then held.

Liquidity, Capital Resources and Going Concern

2026 Liquidity Forecast and Going Concern Qualification

During the six months ended June 30, 2026, the Company completed the sale of Minera William for cash consideration of approximately $1.2 million and a private placement for aggregate gross proceeds of approximately $0.9 million (net cash proceeds of approximately $0.8 million). These transactions improved the Company’s cash position. As of June 30, 2026, we had current assets of approximately $2.6 million, including consolidated cash and cash equivalents of approximately $2.5 million, and accounts payable and other current liabilities of approximately $1.0 million. Based on the Company’s internal assessment, we expect our cash resources to fund operations into early to mid-2027.

The Company’s only near-term opportunity to generate cash flow to meet its expected cash requirements is from asset sales, equity, or other external financing. The Company has been evaluating and pursuing strategic alternatives to address its liquidity requirements. Notwithstanding the improved near-term liquidity from the transactions entered into during the period ended June 30, 2026, the Company has no revenue-generating operations and will require additional financing or asset monetization to sustain operations beyond the current forecast horizon. These conditions continue to raise substantial doubt about the Company’s ability to continue as a going concern.

2026 Liquidity Discussion

At June 30, 2026, our aggregate consolidated cash and cash equivalents totaled approximately $2.5 million, compared to $1.3 million (plus $0.5 million of cash restricted for settlement of a value-added tax payable) at December 31, 2025. There was no restricted cash at June 30, 2026, as the value-added tax payable was settled during the period. During the six months ended June 30, 2026, cash, cash equivalents and restricted cash increased by approximately $0.6 million, reflecting the following:

●

approximately $1.2 million of proceeds from the sale of Minera William;

●

approximately $0.8 million of net proceeds from the private placement; and

●

partially offset by approximately $1.4 million used in operating activities, comprising general and administrative and exploration expenditures.

See Note 2 to the condensed consolidated financial statements and “—2026 Liquidity Forecast and Going Concern Qualification” above for further discussion of the substantial doubt about the Company’s ability to continue as a going concern.

Although we believe the expectations and assumptions reflected in those forward-looking statements are reasonable, we cannot assure you that these expectations and assumptions will prove to be correct. Our actual results could differ materially from those expressed or implied in these forward-looking statements as a result of various factors described in this Form 10-Q, including:

●

The Company’s expected near-term cash needs, including the need to raise additional cash in the near-term and whether we are able to raise the necessary capital required to continue our business on terms acceptable to us or at all;

●

Higher than anticipated exploration, maintenance, general and administrative costs;

●

Plans regarding further advancement of the Sarita Este/Desierto project, including whether we are able to complete the Desierto joint venture documents with Cascadero Copper Corporation;

●

Plans regarding further advancement of the Sand Canyon project, including whether we are able to complete the joint venture documents with Golden Gryphon Explorations, Inc.;

●

Risks related to our exploration properties, including unfavorable results from exploration and whether we will be able to advance our exploration properties;

●

Variations in the nature, quality and quantity of any mineral deposits that are or may be located at our exploration properties, changes in interpretations of geological information, and unfavorable results of drilling, metallurgical and other tests;

●

Potential delays in our exploration activities or other activities to advance properties towards mining resulting from environmental consents or permitting delays or problems, accidents, problems with contractors, disputes under or inability to complete agreements related to exploration properties, high or unanticipated costs and other unexpected events;

●

Our ability to retain key management and exploration personnel necessary to successfully operate and grow our business;

●

Economic and political events negatively affecting the market prices for gold, silver, zinc, lead and other minerals that may be found on our exploration properties;

●

Political and economic instability in Argentina and other countries in which we conduct our business, and future actions of any of these governments with respect to nationalization of natural resources or other changes in mining or taxation policies;

●

Adverse technological changes and cybersecurity threats;

●

Volatility in the market price of our common stock; and

●

The factors discussed under “Risk Factors” in our 2025 Annual Report.

These factors are not intended to represent a complete list of the general or specific factors that could affect us. Many of these factors are beyond our ability to control or predict. Although we believe that the expectations reflected in our forward-looking statements are based on reasonable assumptions, such expectations may prove to be materially incorrect due to known and unknown risks and uncertainties. You should not unduly rely on any of our forward-looking statements. These statements speak only as of the date of this Quarterly Report on Form 10-Q. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.

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 six months ended June 30, 2026, 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, services, supplies and capital assets are denominated in other currencies, primarily in Argentina. 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.

Commodity Price Risk

We are primarily engaged in the exploration 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.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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 June 30, 2026, (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.

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.
