NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Business and Significant Accounting Policies

Business and company formation

Solitario Resources Corp. (“Solitario,” or the “Company”) is an exploration stage company as defined by rules issued by the United States Securities and Exchange Commission (“SEC”). Solitario was incorporated in the state of Colorado on November 15, 1984 as a wholly owned subsidiary of Crown Resources Corporation. In July 1994, Solitario became a publicly traded company on the Toronto Stock Exchange through its initial public offering. Solitario has been actively involved in mineral exploration since 1993. Solitario’s primary business is to acquire exploration mineral properties or royalties and/or discover economic deposits on its mineral properties and advance these deposits, either on its own or through joint ventures, up to the development stage. At or prior to development, Solitario would likely attempt to sell its mineral properties, pursue their development either independently or through a joint venture with a partner that has expertise in mining operations, or create a royalty with a third party that would continue to advance the property. Solitario has never developed a property. Solitario is primarily focused on the exploration of its precious metal, zinc and other base metal exploration mineral properties. In addition, Solitario evaluates new mineral properties for potential acquisition, and from time-to-time evaluates potential strategic transactions for the acquisition of new precious and base metal properties and assets with exploration potential or business combinations that Solitario determines to be favorable.

Solitario has recorded revenue in the past from the sale of mineral properties, including the sale of certain mineral royalties. Revenues and / or proceeds from the sale or joint venture of properties or assets, although potentially significant when they occur, have not been a consistent annual source of cash and would only occur in the future, if at all, on an infrequent basis.

Solitario currently considers its carried interest in the Florida Canyon zinc project in Peru (the “Florida Canyon project”), its interest in the Lik zinc project in Alaska (the “Lik project”), and its Golden Crest project in South Dakota (the “Golden Crest project”) to be its core mineral property assets. Nexa Resources, Ltd. (“Nexa”), Solitario’s joint venture partner, is continuing the exploration and furtherance of the Florida Canyon project and Solitario is monitoring progress at the Florida Canyon project. Solitario is working with its 50% joint venture partner in the Lik project, Teck American Incorporated, a wholly owned subsidiary of Teck Resources Limited (both companies are referred to as “Teck”), to further the exploration and evaluate potential development plans for the Lik project. In addition, Solitario has two early-stage projects, the Cat Creek project in Colorado (the “Cat Creek project”) and the Bright Angel project in Colorado (the “Bright Angel project”). Solitario is conducting mineral exploration on its Golden Crest project, the Cat Creek project and the Bright Angel project on its own.

Solitario anticipates using its cash and short-term investments, in part, to fund costs and activities to further the exploration of its core mineral projects, the Florida Canyon project, Lik project and Golden Crest project, as well as its Cat Creek and Bright Angel projects, and to 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 early-stage and advanced mineral exploration projects or other related assets at potentially attractive terms.

The accompanying interim condensed consolidated financial statements of Solitario for the three and six months ended June 30, 2026 are unaudited and are prepared in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). They do not include all disclosures required by generally accepted accounting principles for annual financial statements, but in the opinion of management, include all adjustments necessary for a fair presentation of the interim results as presented. Interim results are not necessarily indicative of results which may be achieved in the future or for the full year ending December 31, 2026.

These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto which are included in Solitario’s Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 5, 2026 (the “2025 Annual Report”). The accounting policies set forth in those annual financial statements are the same as the accounting policies utilized in the preparation of these condensed consolidated financial statements, except as modified for appropriate interim financial statement presentation.

Table of Contents

Adopted accounting pronouncements

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

Risks and Uncertainties

Solitario is subject to various risks and uncertainties that are specific to the nature of its business and the exploration of its mineral properties. Solitario also faces various macro-economic risks and uncertainties, such as risks related to health epidemics, pandemics, and other outbreaks or resurgences of communicable diseases, the occurrence of natural disasters, rising geopolitical tension and instability, acts of war or terrorism, global economic uncertainty, inflationary pressures, interest rate volatility, and volatility and disruption in national and international financial markets. These risks and uncertainties could significantly disrupt Solitario’s operations and may materially and adversely affect its business and financial condition. Certain of these risks and uncertainties are discussed under the heading “Risk Factors” in Item 1A of our 2025 Annual Report and generally identified under the heading “Forward-Looking Statements.”

Financial reporting

The condensed consolidated financial statements include the accounts of Solitario and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles and are expressed in US dollars.

Cash equivalents

Cash equivalents include investments in highly liquid money-market securities with original maturities of three months or less when purchased. As of June 30, 2026, $50,000 of Solitario’s cash is held in brokerage accounts and foreign banks, which are not covered under the Federal Deposit Insurance Corporation rules for the United States.

Money market funds

Solitario invests in money market funds that seek to maintain a stable net asset value. These funds invest in high-quality, short-term, diversified money market instruments, short-term treasury bills, federal agency securities, certificates of deposits, and commercial paper. Solitario includes its money market funds in short-term investments. Solitario believes the redemption value of these funds is likely to be the fair value, which is represented by the net asset value. Redemption is permitted daily without written notice. At June 30, 2026 Solitario’s money market funds of $8,500,000 are included in short-term investments.

Segment reporting

Solitario operates as a single operating segment in accordance with FASB ASU 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.All financial information is presented on a consolidated basis and reviewed by Solitario’s Chief Executive Officer as the Chief Operating Decision Maker (“CODM”). The CODM uses consolidated net loss, as presented in the condensed consolidated statement of operations, to assess segment performance and allocate resources. The measure of segment assets is reported on the balance sheet as total consolidated assets.

Earnings per share

The calculation of basic and diluted earnings (loss) per share is based on the weighted average number of shares of outstanding common stock during the three and six months ended June 30, 2026 and 2025. Potentially dilutive shares related to outstanding common stock options of 5,425,000 and 5,565,000, respectively, for the three and six months ended June 30, 2026 and outstanding common stock options of 4,570,000 and 4,320,000, respectively, for the three and six months ended June 30, 2025 were excluded from the calculation of diluted loss per share because the effects were anti-dilutive.

2. Mineral Properties

The following table details Solitario’s capitalized mineral properties:

(in thousands)	June 30,		December 31,
	2026		2025
Exploration
Lik Project (Alaska – US)	$	15,611	$	15,611
Golden Crest Project (South Dakota – US)		1,078		1,078
Cat Creek Project (Colorado – US)		12		12
Bright Angel Project (Colorado – US)		31		31
Total exploration mineral properties	$	16,732	$	16,732

Solitario's mineral properties at June 30, 2026 and December 31, 2025 consist of use rights related to its exploration properties. The amounts capitalized as mineral properties include initial concession and lease or option acquisition costs. None of Solitario’s exploration properties have production (are operating) or have established proven or probable reserves. Solitario's mineral properties represent interests in properties that Solitario believes have exploration and development potential.

Exploration expense

The following items comprised exploration expense:

(in thousands)	Three months ended June 30,				Six months ended June 30,
	2026		2025		2026		2025
Geologic and field expenses	$	1,429	$	620	$	1,556	$	782
Administrative		79		51		134		128
Total exploration costs	$	1,508	$	671	$	1,690	$	910

Asset Retirement Obligation and Reclamation Liabilities

Solitario recorded an asset retirement obligation of $125,000 upon the acquisition of its interest in the Lik project for Solitario’s estimated reclamation cost of the existing disturbance at the Lik project. This disturbance consists of an exploration camp including certain drill sites and access roads at the camp. The estimate was based upon estimated cash costs for reclamation as determined by Solitario and its joint venture partner, Teck, and is supported by a permitting bond required by the State of Alaska, for which Solitario has retained a reclamation bond insurance policy in the event Solitario or Teck do not complete required reclamation.

Solitario has not applied a discount rate to the recorded asset retirement obligation as the estimated time frame for reclamation is not currently known, as completion of reclamation is not expected to occur until the end of the related project life, which would follow future development and operations, the start of which cannot be estimated or assured at this time. Additionally, no depreciation will be recorded on the related asset for the asset retirement obligation until the Lik project goes into operation, which cannot be assured.

As of June 30, 2026 and December 31, 2025, Solitario has no reclamation liability at its Florida Canyon Project as Nexa is responsible for the costs at the Florida Canyon project, including reclamation, if any. In addition, the activities to date at Solitario’s Cat Creek and Bright Angel projects of staking claims and mapping, soil and rock sampling, and assaying have not created any material environmental or other disturbances.

Solitario is also involved in certain matters concerning its drilling programs since 2024 through June 30, 2026 regarding remediation at its Golden Crest project. Generally, the bulk of remediation at the Golden Crest project associated with its drilling programs is currently and has been carried out concurrently with drilling activities, with only ongoing contouring and reseeding of drill sites remaining as of June 30, 2026. Solitario has a reclamation liability of $20,000 in asset retirement and reclamation liabilities at both June 30, 2026 and December 31, 2025 related to the drilling on its Golden Crest project.

During the three and six months ended June 30, 2025, Solitario sold its holdings of 100,000 shares of Kinross common stock for gross proceeds of $1,401,000, which was netted by the settlement of $403,000 to close out its $10.00 Kinross covered call covering all 100,000 shares of Kinross previously held by Solitario, which had a May 16, 2025 settlement date, resulting in net proceeds of $998,000, after fees and commissions. Solitario recorded a gain on sale of $1,319,000 on the date of sale. See also Note 7 “Derivative Instruments” below. Also, during the three and six months ended June 30, 2025, Solitario sold 34,055 of its Vox Royalty shares for proceeds of $106,000 and recorded a gain on sale of $32,000 on the date of sale.

Table of Contents

4. Leases

Solitario leased one facility, its Wheat Ridge, Colorado office, that had a term of more than one year (the “WR Lease”). The WR Lease was classified as an operating lease which terminated on February 28, 2026. There is no remaining lease asset or lease liability related to the WR Lease at June 30, 2026. At December 31, 2025, the right-of-use office lease asset for the WR Lease was classified as other long-term assets and the related liability as current operating lease liabilities in the condensed consolidated balance sheet. The amortization of right-of-use lease asset expense was recognized over the lease term, with variable lease payments recognized in the period those payments were incurred.

During the three and six months ended June 30, 2026 cash lease payments of $nil and $7,000, respectively, were made on the WR Lease. During the three and six months ended June 30, 2025, cash lease payments of $11,000 and $22,000, respectively, were made on the WR Lease. During the three and six months ended June 30, 2026 and 2025, Solitario recognized $nil and $7,000, respectively, of non-cash amortization of right-of-use lease asset expense for the WR Lease included in general and administrative expense. During the three and six months ended June 30, 2025, Solitario recognized $10,000 and $20,000, respectively, of non-cash amortization of right of use lease asset expense for the WR Lease included in general and administrative expense. These cash payments less imputed interest for each period, reduced the related liability on the WR Lease. The discount rate within the WR Lease was not determinable and Solitario applied a discount rate of 7% based upon Solitario’s estimate of its cost of capital to determine the asset and liability upon the extension of the WR lease during 2023.

5 Other Assets

Other assets consisted of the following items:

	June 30,		December 31,

Table of Contents

7. Derivative Instruments

From time-to-time Solitario sold covered call options against its prior holdings of shares of common stock of Kinross Gold Corp. (“Kinross”) that were included in its marketable equity securities. The business purpose of selling covered calls was to provide additional income on a limited portion of shares of Kinross that Solitario may sell in the near term, which is generally defined as less than one year and any changes in the fair value of its covered calls are recognized in the statement of operations in the period of the change.

Solitario has no derivative instruments outstanding at June 30, 2026 and December 31, 2025. In August 2024, Solitario sold covered calls against its holdings of Kinross for net proceeds of $39,000. During the three and six months ended June 30, 2025, Solitario recorded a loss on derivative instruments of $130,000 and $336,000, respectively related to its Kinross calls. Solitario settled its Kinross calls in May 2025, upon the sale of its holdings of Kinross.

8. Income Taxes

Solitario accounts for income taxes in accordance with ASC 740 Income Taxes. Under ASC 740, income taxes are provided for the tax effects of transactions reported in the condensed consolidated financial statements and consist of taxes currently due plus deferred taxes related to certain income and expenses recognized in different periods for financial and income tax reporting purposes. Deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred taxes are also recognized for operating losses and tax credits that are available to offset future taxable income and income taxes, respectively. A valuation allowance is provided if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

At both June 30, 2026 and December 31, 2025, a valuation allowance has been recorded, which fully offsets Solitario’s net deferred tax assets, because it is more likely than not that the Company will not realize some portion or all of its deferred tax assets. The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that the deferred tax assets can be realized prior to their expiration.

During the three and six months ended June 30, 2026 and 2025, Solitario recorded no deferred tax expense.

9. Commitments and contingencies

At June 30, 2026 and December 31, 2025, Solitario has recorded an asset retirement and reclamation liability obligation of $145,000, related to its Lik project and Golden Crest project. See Note 2 “Mineral Properties,” above.

10. Employee Stock Compensation Plans

2013 Plan:

On June 18, 2013, Solitario’s shareholders approved the 2013 Solitario Exploration & Royalty Corp. Omnibus Stock and Incentive Plan, as amended (the “2013 Plan”), which expired in April 2023.

At the Market Offering Agreement

On December 19, 2023, Solitario entered into an amendment to its at-the-market offering agreement that was originally entered into in 2021 (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which Solitario may, from time to time, issue and sell shares of Solitario’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 $10.0 million (the “ATM Program”). The common stock is 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 between purchasers and during the period of distribution. The ATM Agreement provides that Wainwright is entitled to compensation for its services at a commission rate of 3.0% of the gross sales price per share of common stock sold.

During the three and six months ended June 30, 2026 Solitario sold 1,747,519 and 3,387,944 shares, respectively, of Solitario common stock under the ATM program at an average price of $0.83 and $0.78, respectively, per share for net proceeds of $1,446,000 and $2,647,000 after commissions and other expenses. During the three and six months ended June 30, 2025, Solitario sold an aggregate of 147,067 shares of common stock under the ATM Agreement at an average price of $0.67 per share for net proceeds of $94,000, after commissions and sale expenses.

Private Placement

On May 13, 2026, Solitario closed on a private placement of 305,195 shares of Solitario common stock, pursuant to a Stock Purchase Agreement (the “SPA”) with Newmont Overseas Exploration Ltd. (“Newmont”), for a price of $0.77 per share for net proceeds of $228,000 after certain legal and regulatory expenses of $7,000.

In June 2025, Solitario closed on a private placement of 1,587,300 shares of Solitario common stock, pursuant to the SPA with Newmont, for a price of $0.63 per share for net proceeds of $980,000 after certain legal and regulatory expenses of $20,000.

In June 2025, Solitario closed on a private placement of 5,555,555 shares of its common stock (the “Shares”) at a price of $0.63 per share for net proceeds of $3,431,000 after certain legal and regulatory expenses of $69,000. The sale of the Shares was made through a subscription agreement between Solitario and a single third-party investor.

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

The following discussion should be read in conjunction with the information contained in the consolidated financial statements of Solitario for the years ended December 31, 2025 and 2024, and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Solitario’s 2025 Annual Report. Solitario's financial condition and results of operations as of and through June 30, 2026 are not necessarily indicative of what may be expected in future periods. Unless otherwise indicated, all references to dollars are to U.S. dollars.

(a) Business Overview and Summary

We are an exploration stage company as defined by rules issued by the SEC, with a focus on the acquisition of precious and base metal properties with exploration potential and the development or purchase of royalty interests. Currently our primary focus is the exploration of our precious metals, zinc and other base metal exploration mineral properties. However, we continue to evaluate other mineral properties for acquisition, and we hold a portfolio of mineral exploration properties and assets for future sale, joint venture or on which to create a royalty prior to the establishment of proven and probable reserves. Although our mineral properties may be developed in the future by us, through a joint venture or by a third party, we have never developed a mineral property. In addition to focusing on our current mineral exploration properties, from time-to-time we also evaluate potential strategic transactions for the acquisition of new precious and base metal properties and assets with exploration potential.

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 June 30, 2026, 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, described 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 in South and North America.

We have recorded revenue in the past from the sale of mineral properties, however revenues and / or proceeds from the sale or joint venture of properties or assets, although generally significant when they have occurred in the past, have not been a consistent source of revenue and would only occur in the future, if at all, on an infrequent basis. We have reduced our exposure to the costs of our exploration activities in the past through the use of joint ventures. Although we anticipate that the use of joint ventures to fund some of our exploration activities will continue for the foreseeable future, we can provide no assurance that these or other sources of capital will be available in sufficient amounts to meet our needs, if at all.

As of June 30, 2026, 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, the Cat Creek project and the 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.

The extent to which our business, including our exploration and other activities and the market for our securities, may be impacted by public health threats, rising geopolitical tension, general economic uncertainty and market volatility will depend on future developments, which are highly uncertain and cannot be predicted at this time. Please see Part I, Item 1A, “Risk Factors,” in our 2025 Annual Report.

(b) Results of Operations

Comparison of the three months ended June 30, 2026 to the three months ended June 30, 2025

We had a net loss of $1,830,000 or $0.02 per basic and diluted share for the three months ended June 30, 2026 compared to a net loss of $943,000 or $0.01 per basic and diluted share for the three months ended June 30, 2025. As explained in more detail below, the primary reasons for the increase in our net loss in the three months ended June 30, 2026 compared to the net loss during the three months ended June 30, 2025 were (i) an increase in exploration expense to $1,508,000 during the three months ended June 30, 2026 compared to exploration expense of $671,000 during the three months ended June 30, 2025;(ii) an increase in general and administrative expense to $451,000 during the three months ended June 30, 2026 compared to general and administrative expense of $388,000 during the three months ended June 30, 2025; and (iii) a decrease in the realized and unrealized gain on marketable equity securities to $56,000 during the three months ended June 30, 2026 compared to a realized and unrealized gain on marketable equity securities of $201,000 during the three months ended June 30, 2025. Partially offsetting these increases in our net loss compared to the prior year period were (i) an increase in interest and dividend income to $77,000 during the three months ended June 30, 2026 compared to interest and dividend income of $52,000 during the three months ended June 30, 2025; and (ii) no loss on derivative instruments during the three months ended June 30, 2026 compared to a loss on derivative instruments of $130,000 during the three months ended June 30, 2025. Each of the major components of these items is discussed in more detail below.

Our net exploration expense increased to $1,508,000 during the three months ended June 30, 2026 compared to exploration expense of $671,000 during the three months ended June 30, 2025 primarily as a result of (i) an increase in exploration expense at our Golden Crest project to $1,404,000 during the three months ended June 30, 2026 compared to $635,000 during the three months ended June 30, 2025 as a result of earlier commencement of drilling at the Golden Crest project during the second quarter of 2026, compared to the drilling in the second quarter of 2025; (ii) an increase in exploration expense at our Lik project in Alaska during the three months ended June 30, 2026 of $25,000 compared to exploration expenditures of $19,000 during the three months ended June 30, 2025; (iii) an increase in exploration expense at our Cat Creek project to $28,000 during the three months ended June 30, 2026 compared with $10,000 during the same period of 2025 and (iv) an increase in exploration expense at our Bright Angel project to $44,000 during the three months ended June 30, 2026, with no exploration expenses during the same period of 2025. Drilling commenced in May 2026 at our Golden Crest project which resulted in approximately $1,140,000 in drilling expenditures in the three months ended June 30, 2026 compared to $347,000 in drilling expenditures in the three months ended June 30, 2025 as drilling did not commence until June in the three months ended June 30, 2025. We have budgeted approximately $5,673,000 for the full-year exploration expenditure for 2026, which includes approximately $2,217,000 for drilling at the Golden Crest Project. We expect our full-year exploration expenditure for 2026 to be higher than our full-year exploration expenditure for 2025.

Exploration expense (in thousands) by project consisted of the following:

	Three months ended June 30,				Six months ended June 30,
Project Name	2026		2025		2026		2025
Golden Crest	$	1,404	$	635	$	1,553	$	851

Reconnaissance		7		7		14		14
Total exploration expense	$	1,508	$	671	$	1,690	$	910

General and administrative costs, excluding stock option compensation costs, discussed below, were $351,000 during the three months ended June 30, 2026 compared to $263,000 during the three months ended June 30, 2025. The major components of our general and administrative costs were (i) salaries and benefit expense of $185,000 during the three months ended June 30, 2026 compared to salary and benefit costs of $79,000 during the three months ended June 30, 2025 as a result of salary increases and bonuses paid in 2026; (ii) legal and accounting expenditures of $54,000 in the three months ended June 30, 2026 compared to $61,000 in the three months ended June 30, 2025; (iii) office rent and expenses of $39,000 during the three months ended June 30, 2026 compared to $17,000 during the three months ended June 30, 2025; and (iv) travel and shareholder relation costs of $73,000 during the three months ended June 30, 2026 compared to $106,000 during the three months ended June 30, 2025. We anticipate the full-year general and administrative costs will be comparable for 2026 and 2025.

We recorded $100,000 of stock option compensation expense for the amortization of unvested grant date fair value with a credit to additional paid-in-capital during the three months ended June 30, 2026 compared to $125,000 of stock option compensation expense during the three months ended June 30, 2025. These non-cash charges related to the expense for vesting on stock options outstanding during the three months ended June 30, 2026 and 2025. The primary reason for the decrease in stock option compensation expense during the three months ended June 30, 2026 compared to the three months ended June 30, 2025 was as a result of certain options from prior years becoming fully vested or forfeited in prior periods with no grant date fair value amortized on those option during the three months ended June 30, 2026 compared to 2025. The remaining expense related to the amortization of grant date fair values of outstanding unvested options for the three months ended June 30, 2026 and 2025 was comparable. See Note 10, “Employee Stock Compensation Plans,” above, for additional information on our stock option expense.

We recorded a realized and unrealized gain on marketable equity securities of $56,000 during the three months ended June 30, 2026 compared to a realized and unrealized gain on marketable equity securities of $201,000 during the three months ended June 30, 2026. The realized and unrealized gains and losses are detailed below.

We recorded a non-cash unrealized loss on marketable equity securities of $82,000 during the three months ended June 30, 2026 compared to an unrealized loss on marketable equity securities of $1,150,000 during the three months ended June 30, 2025. The non-cash unrealized loss on marketable equity securities of $82,000 during the three months ended June 30, 2026 was as a result of (i) a decrease in the fair value of 5,700 shares of Vox Royalty common stock of $3,000 based on quoted market prices, and (ii) the transfer of $138,000 of prior unrealized gain to realized gain on the sale of 34,300 shares of Vox Royalty common stock. These decreases were partially offset by (i) an increase in the fair value of our 7,750,000 shares of Vendetta Mining Corp. (“Vendetta”) common stock of $27,000 during the three months ended June 30, 2026 based on quoted market prices and (ii) an unrealized increase of $32,000 in the value of the 34,300 shares of Vox Royalty sold during the three months ended June 30, 2026.

The non-cash unrealized loss during the three months ended June 30, 2025 of $1,150,000 was related to (i) the transfer $915,000 of unrealized gain on our holdings of Kinross common stock to realized gain upon the sale of shares of Kinross during the three months ended June 30, 2025; (ii) the transfer of $32,000 of unrealized gain on our holdings of Vox Royalty common stock upon the sale of the shares of Vox Royalty during the three months ended June 30, 2025; and (iii) a decrease of $264,000 in the value of the holdings of our Kinross shares during the three months ended June 30, 2025 to the date of sale of the shares. Partially offsetting this non-cash unrealized loss on marketable equity securities during the three months ended June 30, 2025 was (i) an increase of $6,000 on our Vox Royalty common shares sold during the three months ended June 30, 2025 to the date of sale; (ii) an increase of $31,000 in the value of our holdings of Vendetta common stock during the three months ended June 30, 2025; and (iii) an increase of $24,000 in the value of our remaining holdings of Vox Royalty common stock during the three months ended June 30, 2025.

During the three months ended June 30, 2026 we recorded a realized gain on sale of $138,000 from the sale of 34,300 shares of Vox Royalty common stock compared to the three months ended June 30, 2025 when we recorded a realized gain of $1,319,000 from the sale of 100,000 shares of Kinross common stock and a realized gain of $32,000 from the sale of 34,055 shares of Vox Royalty common stock.

We recorded interest and dividend income of $77,000 during the three months ended June 30, 2026 compared to interest income of $52,000 during the three months ended June 30, 2025. This increase was primarily due to an increase in our funds held in our money market account during the three months ended June 30, 2026 compared to the funds held in our money market account during the three months ended June 30, 2025.

During the three months ended June 30, 2025, we recorded a non-cash loss on derivative instruments of $130,000 with no comparable income or loss during the three months ended June 30, 2026, as we no longer held Kinross calls. The Kinross calls were settled upon the sale of our holdings of Kinross common stock, discussed above. See Note 7, “Derivative Instruments,” above for a discussion of our Kinross calls.

We regularly perform evaluations of our mineral property assets to assess the recoverability of our investments in these assets. All long-lived assets are reviewed for impairment whenever events or circumstances change which indicate the carrying amount of an asset may not be recoverable utilizing guidelines based upon future net cash flows from the asset as well as our estimates of the geological potential of an early-stage mineral property and its related value for future sale, joint venture or development by us or others. During the three and six months ended June 30, 2026 and 2025, we recorded no property impairments.

Table of Contents

We recorded no income tax expense or benefit during the three and six months ended June 30, 2026 or 2025 as we provide a valuation allowance for the tax benefit arising out of our net operating losses for all periods presented. As a result of our administrative expenses and exploration activities, we anticipate we will not have currently payable income taxes during 2026. In addition to the valuation allowance discussed above, we provide a valuation allowance for our foreign net operating losses, which are primarily related to our exploration activities in Peru. We anticipate we will continue to provide a valuation allowance for these net operating losses until we are in a net tax liability position with regard to those countries where we operate or until it is more likely than not that we will be able to realize those net operating losses in the future.

Comparison of the six months ended June 30, 2026 to the six months ended June 30, 2025

We had a net loss of $2,324,000 or $0.03 per basic and diluted share for the six months ended June 30, 2026 compared to a net loss of $1,454,000 or $0.02 per basic and diluted share for the six months ended June 30, 2025. As explained in more detail below, the primary reasons for the increase in our net loss were (i) an increase in exploration expense to $1,690,000 during the six months ended June 30, 2026 compared to exploration expense of $910,000 during the six months ended June 30, 2025 and (ii) a decrease in the realized and unrealized gain on marketable equity securities to $58,000 during the six months ended June 30, 2026, compared with a realized and unrealized gain on marketable equity securities of $586,000 during the six months ended June 30, 2025. Partially offsetting these increases in our net loss during the six months ended June 30, 2026 compared to the net loss during the six months ended June 30, 2025 were (i) a decrease in general and administrative expense to $827,000 during the six months ended June 30, 2026 compared to general and administrative expense of $878,000 during the six months ended June 30, 2025; (ii) no loss on derivative instruments during the six months ended June 30, 2026 compared to a loss on derivative instruments of $336,000 during the six months ended June 30, 2025; (iii) an increase in interest and dividend income to $142,000 during the six months ended June 30, 2026 compared to interest and dividend income of $98,000 during the six months ended June 30, 2025 and (iv) a decrease in depreciation to $7,000 during the six months ended June 30, 2026 compared to depreciation expense of $14,000 during the six months ended June 30, 2025. The significant changes for these items are discussed in more detail below.

Our net exploration expense increased to $1,690,000 during the six months ended June 30, 2026 compared to $910,000 during the six months ended June 30, 2025. The primary reasons for the increase were (i) exploration expenditures at our Golden Crest project increased to $1,553,000 during the six months ended June 30, 2026 compared to $851,000 during the six months ended June 30, 2025 as our drilling program in 2026 started earlier in the six months ended June 30, 2026, with drilling and related expenditures of approximately $1,140,000 through June 30, 2026 compared with $347,000 through June 30, 2025; (ii) an increase in our exploration expenditures at our Cat Creek project to $29,000 during the six months ended June 30, 2026 compared to $15,000 during the six months ended June 30, 2025 and (iii) expenditures at our Bright Angel project of $64,000 during the six months ended June 30, 2026, with no similar amount during the six months ended June 30, 2025. We anticipate a significant increase in exploration expenditures at our Cat Creek project in the second half of 2026 primarily due to planned drilling on the project, as discussed above.

General and administrative costs, excluding stock option compensation costs discussed below, were $660,000 during the six months ended June 30, 2026 compared to $627,000 during the six months ended June 30, 2025. The major components of the costs were (i) salary and benefit expense during the six months ended June 30, 2026 of $258,000 compared to salary and benefit expense of $197,000 during the six months ended June 30, 2025; (ii) legal and accounting expenditures of $121,000 during the six months ended June 30, 2026, compared to $114,000 during the six months ended June 30, 2025; (iii) office and other costs of $67,000 during the six months ended June 30, 2026 compared to $46,000 during the six months ended June 30, 2025; and (iv) travel and shareholder relation costs of $214,000 during the six months ended June 30, 2026 compared to $270,000 during the six months ended June 30, 2025.

During the six months ended June 30, 2026 and 2025, Solitario recorded $167,000 and $251,000, respectively, of stock option expense for the amortization of unvested grant date fair value with a credit to additional paid-in capital. The decrease during the six months ended June 30, 2026 was primarily related to a fewer options granted during 2025 compared to 2024, discussed above.

During the six months ended June 30, 2026 Solitario recorded a realized gain of $175,000 and unrealized loss on marketable equity securities of $117,000 netting to a realized and unrealized gain of $58,000 compared to a realized gain of $1,351,000 and unrealized loss of $765,000 netting to a realized and unrealized gain on marketable equity securities of $586,000 during the six months ended June 30, 2025. These are detailed below.

We recorded an unrealized loss on marketable equity securities of $117,000 during the six months ended June 30, 2026 primarily as a result of (i) an unrealized loss on the transfer of prior unrealized gain on the sale of 44,300 shares of Vox Royalty upon their sale of $175,000 and (ii) an unrealized loss during the six months ended June 30, 2026 of $2,000 on our holdings of 7,750,000 shares of Vendetta common stock. These losses were partially offset by (i) an increase in the value of our 5,700 shares of Vox Royalty of $17,000, and (ii) an unrealized gain of $43,000 on our holdings of 44,300 shares of Vox Royalty share through the date of their sale during the six months ended June 30, 2026.

The unrealized loss on marketable equity securities of $765,000 during the six months ended June 30, 2025 was primarily related to (i) the transfer of $915,000 of unrealized gain, as an unrealized loss, on our holdings of Kinross common stock to realized gain upon the sale of shares of Kinross during the three months ended June 30, 2025; and (ii) the transfer of $33,000 of unrealized gain, as an unrealized loss, on our holdings of Vox Royalty common stock upon the sale of the shares of Vox Royalty during the three months ended June 30, 2025. These unrealized losses on marketable equity securities were partially offset by (i) an increase in the value of our holdings of Kinross through the date of sale of $71,000; (ii) an increase in the value of our holdings of Vendetta common stock of $4,000 based on quoted market prices; and (iii) an increase in the value of our Vox Royalty common stock sold of $6,000 through the date of sale for the Vox Royalty shares sold and an increase in the value of remaining holdings of Vox Royalty common stock for the six months ended June 30, 2025 of $102,000.

Our realized gain on marketable equity securities of $175,000 during the six months ended June 30, 2026 was from the sale of 44,300 shares of Vox Royalty shares for net proceeds of $270,000. The realized gain of $1,351,000 during the six months ended June 30, 2025 was from (i) $915,000 transferred from unrealized gain upon the sale of 100,000 shares of Kinross, (ii) $33,000 transferred from unrealized gain upon the sale of Vox Royalty shares and (iii) the recognition of the proceeds of $403,000 for the settlement of the Kinross calls upon the sale of the Kinross shares.

We recorded interest and dividend income of $142,000 during the six months ended June 30, 2026 compared to interest and dividend income of $98,000 during the six months ended June 30, 2025. The increase in interest income was primarily related to an increase in our average outstanding balance of money market holdings during the six months ended June 30, 2026 compared to the six months ended June 30, 2025. We anticipate interest income will decrease during the remainder of 2026, as a result of the use of funds in the money market account to fund our exploration and general and administrative expenditures. See “Liquidity and Capital Resources” below for further discussion of our cash and short-term investment balances.

During the six months ended June 30, 2025, we recorded a non-cash loss on derivative instruments of $336,000 related to the Kinross calls held during the six months ended June 30, 2025 as a result of the increase in the underlying value of our holdings of Kinross common stock, discussed above. These calls were settled during the six months ended June 30, 2025 upon the sale of our holdings of Kinross, with no similar loss or gain on derivative instruments during the six months ended June 30, 2026.

(c) Liquidity and Capital Resources

Cash and Short-term Investments

As of June 30, 2026, we have $9,009,000 in cash and short-term investments. Our short-term investments are comprised of $8,500,000 invested in a money market account with a brokerage firm. We anticipate we will roll over that portion of our short-term investments not used for exploration expenditures, operating costs or mineral property acquisitions as they become due during the remainder of 2026. We intend to utilize a portion of our cash and short-term investments in our exploration activities and the potential acquisition of mineral assets over the next several years.

Table of Contents

Investment in Marketable Equity Securities

Our marketable equity securities are carried at fair value, which is based upon market quotes of the underlying securities. At June 30, 2026, we owned 7,750,000 shares of Vendetta common stock and 5,700 shares of Vox common stock. At June 30, 2026, the Vendetta shares are recorded at their fair value of $55,000, and the Vox shares are recorded at their fair value of $27,000. During the six months ended June 30, 2026 we sold 44,300 shares of our Vox Royalty common stock for proceeds of $270,000 and recorded a realized gain on sale of $175,000. We sold our 100,000 shares of Kinross during the six months ended June 30, 2025 for net proceeds of $998,000, after settlement of our outstanding Kinross call, and recorded a realized gain on sale of $915,000, and we sold 34,055 shares of Vox Royalty shares for net proceeds of $106,000 and recorded a realized gain on sale of $33,000. We anticipate we may sell a portion of our holdings of marketable equity securities during the remainder of 2026 depending on cash needs and market conditions.

Working Capital

We had working capital of $8,584,000 at June 30, 2026 compared to working capital of $7,795,000 at December 31, 2025. Our working capital at June 30, 2026 consists primarily of our cash and cash equivalents, our short-term investments, discussed above, our investment in marketable equity securities of $82,000, and other current assets of $143,000, less our accounts payable of $650,000. The increase in our working capital from December 31, 2025 is primarily the result of our receipt of cash proceeds from sales of our common stock under the ATM Program and in a private placement that we completed in May 2026. As of June 30, 2026, our cash balances along with our short-term investments and marketable equity securities are adequate to fund our expected expenditures over the next year.

The nature of the mineral exploration business requires significant sources of capital to fund exploration, development and operation of mining projects. We will need additional capital if we decide to develop or operate any of our current exploration projects or any projects or assets we may acquire. We anticipate we would finance any such development through the use of our cash reserves, short-term investments, joint ventures, issuance of debt or equity, or the sale of our interests in other exploration projects or assets.

Stock-Based Compensation Plans

As of June 30, 2026, there were options outstanding from the 2013 Plan to acquire an aggregate of 1,825,000 shares of Solitario common stock, all with an exercise price of $0.60 per share. As of December 31, 2025, there were options outstanding from the 2013 Plan to acquire an aggregate of 1,965,000 shares of Solitario common stock, with exercise prices between $0.60 and $0.69 per share. As of both June 30, 2026 and December 31, 2025 there were options outstanding under the 2023 Plan to acquire 3,600,000 shares of Solitario common stock with exercise prices between $0.51 per share and $0.85 per share. We did not grant any options during the three and six months ended June 30, 2026 or 2025. During the three and six months ended June 30, 2026, options for 90,000 shares of Solitario common stock were exercised under the 2013 Plan with exercise prices between $0.69 and $0.67 per share for proceeds of $61,000. During the three and six months ended June 30, 2025, options for 250,000 and 1,028,500 shares, respectively, of Solitario common stock were exercised under the 2013 Plan with an exercise price of $0.20 per share for proceeds of $50,000 and $206,000, respectively. We do not anticipate the exercise of options to be a significant source of capital during the remainder of 2026.

(d) Cash Flows

Net cash used in operations during the six months ended June 30, 2026 increased to $1,848,000 compared to $1,401,000 of net cash used in operations for the six months ended June 30, 2025 primarily as a result of (i) an increase in exploration expenses to $1,690,000 during the six months ended June 30, 2026 compared to exploration expenses of $910,000 during the six months ended June 30, 2025. Partially offsetting this increase in the use of cash were (i) a decrease in general and administrative expense during the six months ended June 30, 2026 to $827,000 compared to $878,000 during the six months ended June 30, 2025; (ii) an increase in interest and dividend income to $142,000 during the six months ended June 30, 2026 compared to interest income of $98,000 during the six months ended June 30, 2025; (iii) a reduction in the use of cash for prepaid expenses and other current assets to $82,000 for the six months ended June 30, 2026 compared to the use of cash of $163,000 for prepaid expenses and other current assets during the six months ended June 30, 2025. and (iv) a provision of cash from an increase in accounts payable and other current liabilities during the six months ended June 30, 2026 of $435,000 compared to a provision of cash for an increase in accounts payable and other current liabilities of $181,000 during the six months ended June 30, 2025. Based upon projected expenditures in our 2026 budget, we anticipate continued use of funds from operations through the remainder of 2026, primarily for exploration related to our Golden Crest and Cat Creek project as well as our Bright Angel and Lik projects and reconnaissance exploration. See “Results of Operations” above for further explanation of some of these variances.

Table of Contents

During the six months ended June 30, 2026, we used $927,000 for net purchases of short-term investments, compared to the use of cash of $4,300,000 for net purchases of short-term investments during the six months ended June 30, 2025. The increase during 2025 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.

We will continue to liquidate a portion of our short-term investments as needed to fund our operations and any potential mineral property acquisitions during the remainder of 2026, although we are not currently planning any potential mineral property acquisition or strategic corporate investment during the remainder of 2026. However, any such activity could involve a significant change in our cash provided or used for investing activities, depending on the structure of any potential transaction.

During the six months ended June 30, 2026, we received $2,647,000 in net proceeds from the issuance of common stock under the ATM Program, and we received $228,000 from a private placement by Newmont. We also received $61,000 from the exercise of stock options during the six months ended June 30, 2026. During the six months ended June 30, 2025, we received $94,000 in net proceeds from the issuance of common stock under the ATM Program, and we received $4,411,000 from the issuance of common stock from private placements. We also received $206,000 from the exercise of stock options during the six months ended June 30, 2025. See Note 11, Shareholders’ Equity, above.

(e) Mineral Resources

CAUTIONARY NOTE REGARDING DISCLOSURE OF MINERAL PROPERTIES

Mineral Reserves and Resources

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and applicable Canadian securities laws, and as a result we are subject to reporting our mineral resources according to two different standards. U.S. reporting requirements, are governed by Item 1300 of Regulation S-K (“S-K 1300”) issued by the SEC. Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 Standards of Disclosure for Mineral Projects adopted from the definitions provided by the Canadian Institute of Mining, Metallurgy and Petroleum. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards generally embody slightly different approaches and definitions.

In our public filings in the U.S. and Canada and in certain other announcements not filed with the SEC, we disclose measured, indicated and inferred resources, each as defined in S-K 1300. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves, and therefore investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into S-K 1300-compliant reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources, and therefore it cannot be assumed that all or any part of inferred resources will ever be upgraded to a higher category. Therefore, investors are cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically.

(f) Off-balance sheet arrangements

As of June 30, 2026 and December 31, 2025, we had no off-balance sheet obligations.

Table of Contents

(g) Development Activities, Exploration Activities, Environmental Compliance and Contractual Obligations

We are not involved in any development activities, nor do we have any contractual obligations related to any potential development activities as of June 30, 2026. As of June 30, 2026, there have been no material changes to our contractual obligations for exploration activities, environmental compliance or other obligations from those disclosed in our Management’s Discussion and Analysis included in our 2025 Annual Report.

(h) Discontinued Projects

We did not record any mineral property write-downs during the three and six months ended June 30, 2026 and 2025.

(i) Significant Accounting Policies and Critical Accounting Estimates

See Note 1 to the consolidated Financial Statements included in our 2025 Annual Report for a discussion of our significant accounting policies.

Solitario’s valuation of mineral properties is a critical accounting estimate. We review and evaluate our mineral properties for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Significant negative industry or economic trends, adverse social or political developments, geologic results, geo-technical difficulties, or other disruptions to our business are a few examples of events that we monitor, as they could indicate that the carrying value of the mineral properties may not be recoverable. In such cases, a recoverability test may be necessary to determine if an impairment charge is required. There has been no change to our assumptions, estimates or calculations during the three and six months ended June 30, 2026.

(j) Related Party Transactions

As of June 30, 2026, and for the three and six months ended June 30, 2026, we have no related party transactions or balances.

(k) Recent Accounting Pronouncements

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

There can be no assurance that these statements will prove to be accurate as actual results and future events could differ materially from those anticipated in the statements. Except as required by law, we assume no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
