Q1 2026 Business Summary

During the first quarter of 2026, the Company continued to focus on preserving cash resources, maintaining a significantly reduced cost structure, managing its exploration portfolio and evaluating strategic alternatives.

Subsequent to quarter end, on May 14, 2026, the Company completed the sale of all of the issued and outstanding shares of Minera William, S.A. de C.V. ("Minera William") to Streamline Metals Capital Ltd. for total consideration of $1.2 million. The assets of Minera William include net operating losses, a Capital Contribution Account ("CUCA"), the Par de Tres 2 mining concession and the San Diego royalty. With the completion of this transaction, the Company has substantially concluded its business in Mexico and is focused on its exploration properties in Argentina and Nevada.

In connection with the sale of Minera William, the Company entered into a private placement agreement with Streamline Metals Capital Ltd. pursuant to which the Company agreed to issue 3,740,000 shares of common stock at a purchase price of $0.2290 per share for aggregate gross proceeds of approximately $856,000. The private placement remains subject to approval of the Toronto Stock Exchange and is expected to close on or around May 20, 2026. The proceeds from the Minera William sale and the private placement are not reflected in the Company's March 31, 2026 financial statements.

The Company controls 67% of the Desierto Project, located in the Puna geological region of Salta Province, Argentina. During the first quarter of 2026, the Company continued discussions with Cascadero Copper Corporation regarding joint venture arrangements. 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 remains subject to completion of joint venture documentation and the availability of sufficient funding.

In January 2025, the Company exercised its option to earn a 60% interest in the Sand Canyon Project, an exploration-stage gold-silver project located in Humboldt County, Nevada. The parties continue to finalize joint venture documentation. During the first quarter of 2026, no drilling was planned, and the Company continued to review historical exploration data to inform future exploration planning.

2026 Liquidity Discussion

At March 31, 2026, the Company had aggregate cash and cash equivalents of $0.9 million, compared to $1.3 million in cash and cash equivalents (plus restricted cash of $0.5 million). Combined cash, cash equivalents and restricted cash decreased by $0.9 million during the three months ended March 31, 2026, primarily reflecting:

• a $0.5 million disbursement of restricted cash to settle value added tax obligations of subsidiaries disposed of during 2025;

• $0.5 million in general and administrative expenses;

• $0.06 million in exploration expenditures; and

• $14,000 of income from discontinued operations.

The Company continued to operate with a reduced cost structure during the quarter, while preserving capital for corporate purposes and maintaining its exploration portfolio in Argentina and Nevada.

Capital Resources and 2026 Financial Outlook

The Company does not currently have sufficient resources to meet its expected cash needs for a period of twelve months beyond the filing date of its Quarterly Report on Form 10-Q for the quarter ended March 31, 2026. At March 31, 2026, the Company had current assets of approximately $1.0 million, including cash and cash equivalents of approximately $0.9 million, and accounts payable and other current liabilities of approximately $0.9 million.

Subsequent to March 31, 2026, the Company completed the sale of Minera William, S.A. de C.V. for total proceeds of $1.2 million. In connection with that transaction, the Company also entered into a private placement agreement to issue 3,740,000 shares of common stock at a purchase price of $0.2290 per share for expected gross proceeds of approximately $856,000. The private placement remains subject to approval of the Toronto Stock Exchange and is expected to close on or around May 20, 2026.

Based on current forecasts and taking into account the completed sale of Minera William and the expected proceeds from the private placement, the Company expects its cash resources to fund its cash requirement into early 2027. The Company's only near-term opportunities to generate cash flow to meet its expected cash requirements are from the sale of additional assets, equity or other external financing. The Company is evaluating alternatives, including the potential sale of the Company, seeking buyers or partners for certain of the Company's remaining assets, or obtaining equity or other external financing.
