Q3 2025 Business Summary

The Company achieved a significant reduction in liabilities and a meaningful decrease in its cost structure through restructuring efforts initiated in 2024 and continued through the first nine months of 2025. These combined actions strengthened the Company's balance sheet and preserved capital, which will enable the Company to focus on advancing its most prospective exploration assets, as further described below.

The Velardeña Properties transaction closed on October 10, 2025, for a total purchase price of US$3.0 million plus applicable value-added tax (VAT). The full amount has been received, marking the successful completion of the sale. With this closing, the Company has now fully divested its Velardeña operations.

The Desierto Project, located in the Puna geological region of Salta Province, Argentina, has been the subject of surface exploration that has identified alteration zones enriched in clay and silica, characteristics typically associated with precious metal systems. Rock sampling across multiple zones has returned anomalous gold and silver values, and the observed alteration patterns suggest the presence of a potentially larger mineralizing system at depth. The Company anticipates initiating a Phase I drill program targeting extensions of gold mineralization identified at the adjacent Sarita Este Project. The Company is working on joint venture documentation and continues to integrate historical drilling data to refine its regional geological model.

In January 2025, the Company exercised its option to earn-in a 60% interest in the Sand Canyon Project, located in Nevada, pursuant to its agreement with Golden Gryphon Explorations, Inc. The parties are currently finalizing joint venture documentation. While no drilling is planned for 2025, the Company continues to review and integrate historical exploration data and technical studies to support future exploration planning.

2025 Liquidity Discussion

At September 30, 2025, aggregate cash and cash equivalents totaled $1.7 million, compared to $3.2 million at December 31, 2024. The September 30, 2025, decrease is the result of the following expenditures and cash flows for the Nine months ended September 30, 2025.

• $0.3 million cash spent on discontinued operations, primarily related to care and maintenance cost of the Velardeña properties;

• $2.9 million in general and administrative and exploration expenditures.

The above expenditures were partially offset by cash inflows of $1.8 million from the following:

• $1.2 million of proceeds received from the sale of Velardeña Plant 2 and water wells; and

• $0.6 million from the sale of Minera de Cordilleras.

Capital Resources and 2025 Financial Outlook

The Company does not currently have sufficient resources to meet our expected cash needs for a period of twelve months beyond the filing date of this 2025 Quarterly Report on Form 10-Q. At September 30, 2025, we had current assets of approximately $2.0 million, including cash and cash equivalents of approximately $1.7 million. On the same date, we had accounts payable and other current liabilities of approximately $4.3 million, which includes $2.97 million in deferred revenue for the sale of the Velardeña oxide plant and water wells recorded within Current liabilities held for sale on the interim Condensed Consolidated Balance Sheets. As previously disclosed, the Company ceased mining at the Velardeña mines in Mexico in the first quarter 2024 and subsequently sold the mines and certain related assets. As of September 30, 2025, the Company was owed $28,000 plus $5,000 value-added tax ("VAT") of the $3.0 million purchase price plus VAT for the Velardeña Properties. This remaining amount was received during October 2025 and as a result, the Company will recognize the related gain from sale of Velardeña Properties on its 2025 Annual Report.

The Company's only near-term opportunity to generate cash flow to meet its expected cash requirements is from the sale of assets, 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. In the absence of additional cash inflows, the Company anticipates that its cash resources will be exhausted in approximately the second quarter of 2026. If we are unable to obtain additional cash resources or sell the Company, we will be forced to cease operations and liquidate.
