Current report

Our exploration expense decreased to $182,000 during the three months ended March 31, 2026 compared to exploration expense of $239,000 during the three months ended March 31, 2025. The decrease was primarily a result of (i) a decrease in expenses at our Golden Crest project to $149,000 during the three months ended March 31, 2026 compared to exploration expense of $216,000 during the three months ended March 31, 2025; (ii) a decrease in our exploration expenditures at our Lik project to $5,000 during the three months ended March 31, 2026 compared to $11,000 during the three months ended March 31, 2025; and (iii) a reduction in our exploration expenditures at our Cat Creek project to $1,000 during the three months ended March 31, 2026 compared to $5,000 during the three months ended March 31, 2025. These reductions in costs were partially offset by the expenditures of $20,000 at our Bright Angel project during the three months ended March 31, 2026, with no expenditures for that project in the prior year period. Our full-year 2026 total exploration and development budget is approximately $5,673,000, which reflects potential drilling programs both at the Golden Crest project during 2026 budgeted at $2,217,000 and the Cat Creek project during 2026 budgeted at $516,000 as well as a proposed limited exploration program at the Lik and Bright Angel projects. All of the planned drilling during 2026 is dependent on receiving required permits and availability of third-party drilling contractors. Nexa is responsible for all planned 2026 exploration expenditures at the Florida Canyon Project. The proposed 2026 budget does not reflect any exploration costs for new projects or assets we may acquire during 2026. Our planned exploration activities in 2026 may be modified, as necessary for any drilling programs we may undertake or other projects we may acquire. Changes may occur to our planned 2026 exploration expenditures related to any number of factors including permitting delays, potential acquisition of new properties, joint venture funding, commodity prices and changes in the deployment of our capital. We expect our full-year exploration expenditures for 2026 to be higher than the exploration expenditures for full-year 2025.

Current report

We recorded interest and dividend income of $65,000 during the three months ended March 31, 2026 compared to interest income of $46,000 during the three months ended March 31, 2025. The increase in interest income is related to an increase in the balance of our short-term investments during the three months ended March 31, 2026 compared to the three months ended March 31, 2025 primarily as a result of ATM equity sales during the 2026 period in excess of exploration and other expenditures during the three months ended March 31, 2026. We anticipate our interest income will be comparable during the full year of 2026 and 2025 as we plan to use our short-term investments and our cash balances during the remainder of 2026 for ordinary overhead, operational costs, and the exploration, evaluation and / or acquisition of mineral properties discussed above. See “Liquidity and Capital Resources” below for further discussion of our cash and cash equivalent balances.

Current report

During the three months ended March 31, 2026 we sold 1,640,425 shares of Solitario common stock through our ATM program at an average price of $0.76 per share for net proceeds of $1,201,000 after commissions and other expenses. We did not issue any shares through our ATM program during the three months ended March 31, 2025. During the three months ended March 31, 2025 we received $156,000 from the issuance of common stock from the exercise of stock options, discussed above in Note 10, “Employee Stock Compensation Plans,” to the condensed consolidated financial statements. No options were exercised during the three months ended March 31, 2026. We anticipate we may issue additional shares through the ATM program during the remainder of 2026, depending on our cash needs and market conditions.

There have been no new proposed or adopted accounting pronouncements applicable to Solitario since those described in the Company’s 2025 Annual Report.

Previous report

Our net exploration expense decreased to $1,645,000 during the three months ended September 30, 2025 compared to exploration expense of $2,067,000 during the three months ended September 30, 2024 primarily as a result of (i) lower exploration expense at our Golden Crest Project to $1,522,000 during the three months ended September 30, 2025 compared to $1,957,000 during the three months ended September 30, 2024 as a result of fewer holes being drilled as well as a slightly lower cost per hole for our drilling program during the three months ended September 30, 2025 compared to the drilling program during the three months ended September 30, 2024; and (ii) reductions in our exploration activity at our Cat Creek Project and reconnaissance work during the three months ended September 30, 2025 to $15,000 compared to exploration expense of $29,000 for those projects during the three months ended September 30, 2024. Partially offsetting these decreases in exploration expense were (i) an increase in exploration expense at our Lik Project in Alaska to $102,000 during the three months ended September 30, 2025 compared to exploration expense of $81,000 during the three months ended September 30, 2024; and (ii) work performed at our newly-acquired Bright Angel Project during the three months ended September 30, 2025 of $6,000 with no similar expenditures in 2024. We have budgeted approximately $3,910,000 for the full-year exploration expenditure for 2025, which includes approximately $1,911,000 for drilling at the Golden Crest Project. We expect our full-year exploration expenditure for 2025 to be comparable to our full-year exploration expenditure for 2024.

Previous report

We recorded interest and dividend income of $82,000 during the three months ended September 30, 2025 compared to interest income of $94,000 during the three months ended September 30, 2024. This decrease was primarily due to a decrease in our funds held in our money market account during the three months ended September 30, 2025 compared to the funds held in our money market account during the three months ended September 30, 2024 as well as a lower average interest rate earned on our short-term money market account during the three months ended September 30, 2025 compared to 2024. In addition, we did not earn any dividend income during the three months ended September 30, 2025 compared to dividend income of $3,000 during the three months ended September 30, 2024 from our holdings of Kinross common stock, which was sold in May 2025.

Comparison of the nine months ended September 30, 2025 to the nine months ended September 30, 2024

Previous report

We had a net loss of $3,324,000 or $0.04 per basic and diluted share for the nine months ended September 30, 2025 compared to a net loss of $3,768,000 or $0.05 per basic and diluted share for the nine months ended September 30, 2024. As explained in more detail below, the primary reasons for the decrease in our net loss were (i) a decrease in exploration expense to $2,555,000 during the nine months ended September 30, 2025 compared to exploration expense of $2,908,000 during the nine months ended September 30, 2024; (ii) a decrease in general and administrative expense to $1,257,000 during the nine months ended September 30, 2025 compared to general and administrative expense of $1,511,000 during the nine months ended September 30, 2024; and (iii) a realized and unrealized gain on sale of marketable equity securities of $666,000 during the nine months ended September 30, 2025, compared with an unrealized and realized gain on sale of marketable equity securities of $420,000 during the nine months ended September 30, 2024. Partially offsetting these decreases in the net loss during the nine months ended September 30, 2025 compared to the net loss during the nine months ended September 30, 2024 were (i) an increase in the loss on derivative instruments to $336,000 during the nine months ended September 30, 2025 compared to a loss on derivative instruments of $43,000 during the nine months ended September 30, 2024; and (ii) a decrease in interest and dividend income to $180,000 during the nine months ended September 30, 2025 compared to interest and dividend income of $295,000 during the nine months ended September 30, 2024. The significant changes for these items are discussed in more detail below.

Previous report

Our net exploration expense decreased to $2,555,000 during the nine months ended September 30, 2025 compared to $2,908,000 during the nine months ended September 30, 2024. The primary reasons for the decrease were (i) exploration expenditures at our Golden Crest Project decreased to $2,373,000 during the nine months ended September 30, 2025 compared to $2,742,000 during the nine months ended September 30, 2024 as our drilling program during 2025 included fewer holes and a slightly lower cost per hole compared to our drilling program during 2024. In addition our expenses at our Golden Crest Project were lower as a result of a reduction in permitting and other activities at the Golden Crest Project during the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024; (ii) a decrease in expenditures at our Cat Creek Project during the nine months ended September 30, 2025 to $24,000 compared to the nine months ended September 30, 2024 of $32,000; and (iii) a reduction in reconnaissance exploration expenditures to $20,000 during the nine months ended September 30, 2025 compared to reconnaissance exploration expenditures of $29,000 during the nine months ended September 30, 2024. Partially offsetting these increases in exploration expenditures were (i) an increase in our exploration expenditures at our Lik Project in Alaska to $132,000 during the nine months ended September 30, 2025 compared to $105,000 during the nine months ended September 30, 2024; and (ii) initial work at our newly acquired Bright Angel Project of $6,000 during the nine months ended September 30, 2025. We do not expect significant additional exploration expenditures during the fourth quarter of 2025 as our drilling program ended shortly after the end of September 2025.

Previous report

General and administrative costs, excluding stock option compensation costs discussed below, were $893,000 during the nine months ended September 30, 2025 compared to $971,000 during the nine months ended September 30, 2024. The major components of the costs were (i) salary and benefit expense during the nine months ended September 30, 2025 of $275,000 compared to salary and benefit expense of $292,000 during the nine months ended September 30, 2024; (ii) legal and accounting expenditures of $170,000 during the nine months ended September 30, 2025, compared to $180,000 during the nine months ended September 30, 2024; (iii) office and other costs of $96,000 during the nine months ended September 30, 2025 compared to $104,000 during the nine months ended September 30, 2024; and (iv) travel and shareholder relation costs of $352,000 during the nine months ended September 30, 2025 compared to $395,000 during the nine months ended September 30, 2024.

Previous report

During the nine months ended September 30, 2025 and 2024, Solitario recorded $364,000 and $540,000, respectively, of stock option expense for the amortization of unvested grant date fair value with a credit to additional paid-in capital. The increase during the nine months ended September 30, 2024 was primarily related to the grant of options for a total of 2,125,000 shares of our common stock during June of 2024, which resulted in the amortization of $280,000 of grant date fair value on the date of grant of those options.

Previous report

We recorded a realized and unrealized gain on marketable equity securities of $666,000 during the nine months ended September 30, 2025 compared to a realized and unrealized gain on marketable equity securities of $420,000 during the nine months ended September 30, 2024. These amounts represent a realized gain on the sale of an aggregate of $1,411,000 during the nine months ended September 30, 2025, which was comprised of (i) a realized gain on the sale of our Kinross common stock of $915,000; (ii) a realized gain of $93,000 on the sale of our Vox Royalty common stock; and (iii) a realized gain from the settlement of our call on Kinross stock of $403,000. This realized gain during the nine months ended September 30, 2025 compared to a realized gain of $54,000 during the nine months ended September 30, 2024 from the sale of our Highlander Silver common stock. In addition, we recorded an unrealized loss on marketable equity securities of $745,000 during the nine months ended September 30, 2025 compared to an unrealized gain on marketable equity securities of $366,000 during the nine months ended September 30, 2024. The non-cash unrealized gain during the nine months ended September 30, 2025 was primarily related to (i) the transfer of $915,000 of unrealized gain on our holdings of Kinross common stock to realized gain upon the sale of shares of Kinross during the nine months ended September 30, 2025; and (ii) the transfer of $92,000 of unrealized gain on our holdings of Vox Royalty common stock upon the sale of the shares of Vox Royalty common stock during the nine months ended September 30, 2025. These transfers of prior unrealized gains (as an unrealized loss) in the value of our marketable equity securities during the nine months ended September 30, 2025 along with a decrease in the value of our holdings of Vendetta common stock of $25,000 based on quoted market prices were partially offset by (i) an increase in the value of our holdings of Kinross common stock through the date of sale of $71,000; and (ii) an increase in the value of our Vox Royalty common stock sold of $35,000 through the date of sale for the Vox Royalty shares sold: and (iii) an increase in the value of remaining holdings of Vox Royalty common stock for the nine months ended September 30, 2025 of $181,000. The non-cash unrealized gain during the nine months ended September 30, 2024 was primarily related to (i) an increase in the fair value of our holdings of 100,000 shares of Kinross common stock at September 30, 2024 of $331,000 based on quoted market prices; (ii) an increase in the fair value of our holdings of 134,055 shares of Vox Royalty common stock of $129,000 based on quoted market prices; and (iii) an increase of $22,000 in the fair value of our holdings of 100,000 shares of Highlander common stock to the date of the sale of our holdings of the Highlander shares. These unrealized increases in the value of our marketable equity securities during the nine months ended Se…

Previous report

We recorded interest and dividend income of $180,000 during the nine months ended September 30, 2025 compared to interest and dividend income of $295,000 during the nine months ended September 30, 2024. The decrease in interest income was primarily related to a decrease in our average outstanding balance of money market holdings during the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. We anticipate interest income will increase during the remainder of 2025, as a result of the completion of private placements of our common stock during the second quarter of 2025 for net proceeds of $4,411,000. However, we anticipate we will utilize the funds in the money market account to fund our exploration and general and administrative expenditures, which will mitigate the future interest income during the remainder of 2025 and the sale of our holdings of Kinross common stock will eliminate our dividend income for the remainder of 2025. See “Liquidity and Capital Resources” below for further discussion of our cash and short-term investment balances.

Previous report

During the nine months ended September 30, 2025, we recorded a non-cash loss on derivative instruments of $336,000 related to the Kinross calls, which were settled during the nine months ended September 30, 2025 upon the sale of our holdings of Kinross. During the nine months ended September 30, 2024, we recorded a non-cash loss on derivative instruments of $43,000 related to Kinross calls as a result of an increase in the value of the underlying Kinross common stock.

Previous report

During the nine months ended September 30, 2025, we used $3,050,000 for net purchases of short-term investments, compared to the provision of cash of $2,038,000 for net sales of short-term investments during the nine months ended September 30, 2024. The increase in our short-term investments was as a result of the funds received from (i) the sales of marketable equity securities discussed above; (ii) stock option exercises; and (iii) cash received through stock sales, discussed below. As discussed above, during the nine months ended September 30, 2025 we received $1,631,000 in proceeds from the sale of marketable equity securities less the cash paid for the settlement of our outstanding Kinross call, compared to proceeds of $54,000 from the sale of marketable equity securities during the nine months ended September 30, 2024. During the nine months ended September 30, 2025 we acquired a mineral property of $5,000 compared to mineral property acquisitions of $55,000 during the nine months ended September 30, 2024. During the nine months ended September 30, 2024 we acquired equipment and other assets used in our exploration activities of $12,000, with no similar purchases during the nine months ended September 30, 2025. We received cash proceeds of $39,000 from the sale of Kinross calls during the nine months ended September 30, 2024, with no similar derivative instrument sale during the nine months ended September 30, 2025.

Reworded paragraphs (21)

Previous wording

Our current geographic focus for the evaluation of potential mineral property assets is in North and South America; however, we have conducted property evaluations for potential acquisition in other parts of the world. At September 30, 2025, we consider our Golden Crest Project in South Dakota, our carried interest in the Florida Canyon Project in Peru, and our interest in the Lik Project in Alaska to be our core mineral property assets. In addition, we own the Cat Creek Project in Colorado and the Bright Angel Project in Colorado, neither of which have been explored to the degree of any of our three core assets, identified above. We are conducting exploration activities in the United States on our own at the Golden Crest Project, the Cat Creek Project and the Bright Angel Project, and through joint ventures operated by our partners in Peru at the Florida Canyon Project and in Alaska at the Lik Project. From time to time we also conduct potential acquisition evaluations in other countries located in South and North America.

Current wording

Previous wording

As of September 30, 2025, we have balances of cash and short-term investments that we anticipate using, in part, to (i) fund costs and activities intended to further the exploration of our Lik Project, Florida Canyon Project, Golden Crest Project, Cat Creek Project and Bright Angel Project; (ii) conduct reconnaissance exploration and (iii) potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices contribute to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of advanced mineral exploration projects or other related assets at potentially attractive terms.

As explained in more detail below, the primary reasons for the decrease in our net loss in the three months ended September 30, 2025 compared to the net loss during the three months ended September 30, 2024 were (i) a decrease in exploration expense to $1,645,000 during the three months ended September 30, 2025 compared to exploration expense of $2,067,000 during the three months ended September 30, 2024; (ii) a decrease in general and administrative expense to $379,000 during the three months ended September 30, 2025 compared to general and administrative expense of $383,000 during the three months ended September 30, 2024; and (iii) no loss on derivative instruments during the three months ended September 30, 2025 compared to a loss on derivative instruments of $22,000 during the three months ended September 30, 2024. Partially offsetting these decreases in net loss were (i) a decrease in interest and dividend income to $82,000 during the three months ended September 30, 2025 compared to interest and dividend income of $94,000 during the three months ended September 30, 2024; and (ii) a reduction in the realized and unrealized gain on sale on marketable equity securities to $80,000 during the three months ended September 30, 2025 compared to a realized and unrealized gain on marketable equity securities of $110,000 during the three months ended September 30, 2024.
