Business and Summary of Significant Accounting Policies Business and company formation Solitario Zinc Corp. (“Solitario,” or the “Company”) is an exploration stage company as defined by rules issued by the United States Securities and Exchange Commission (the“SEC”). Solitario was incorporated in the state of Colorado on November 15, 1984 as a whollyowned subsidiary of Crown Resources Corporation ("Crown"). In July 1994, Solitariobecame a publicly traded company on the Toronto Stock Exchange (the "TSX") 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 itsown or through joint ventures, up to the development stage. At that point, or sometime prior to that point, Solitario would likely attempt to sell its mineral properties, pursue theirdevelopment either on its own or through a joint venture with a partner that has expertise in mining operations, or create a royalty with a third party that continues to advance theproperty. Solitario is primarily focused on the acquisition and exploration of precious metal, zinc and other base metal exploration mineral properties. In addition to focusing on itsmineral exploration properties and the evaluation of mineral properties for acquisition, Solitario also evaluates potential strategic transactions for the acquisition of new precious andbase metal properties and assets with exploration potential or business combinations that Solitario determines to be favorable to Solitario. Solitario has recorded revenue in the past from the sale of mineral properties. Revenues and / or proceeds from the sale or joint venture of properties or assets have not been aconsistent 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 project in Peru, its interest in the Lik project in Alaska and its interest in the Golden Crest project in SouthDakota 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 projectand Solitario is monitoring progress at Florida Canyon. Solitario is working with its 50% joint venture partner, Teck American Incorporated, a wholly owned subsidiary of TeckResources Limited (both companies are referred to as “Teck”), in the Lik deposit to further the exploration of the Lik project, and to evaluate potential development plans for the Likproject. Solitario is conducting mineral exploration of its Golden Crest project on its own. As of December 31, 2022 and 2021, Solitario has balances of cash and shortterm investments that Solitario anticipates using, in part, to further the development of the FloridaCanyon project, the Lik project and the Golden Crest project and to potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity priceshave contributed to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of earlystageand advanced mineral exploration projects or other related assets at potentially attractive terms. Financial reporting The consolidated financial statements include the accounts of Solitario and its wholly owned subsidiaries. All significant intercompany accounts and transactions have beeneliminated in consolidation. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("generallyaccepted accounting principles") and are expressed in US dollars. Revenue recognition Solitario has recorded revenue from the sale of exploration mineral properties and joint venture property payments. Solitario’s policy is to recognize revenue from the sale of itsexploration mineral properties (those without reserves) on a propertybyproperty basis, computed as the cash received and / or collectable receivables less any capitalized cost. Payments received for the sale of exploration property interests that are less than the properties cost are recorded as a reduction of the related property's capitalized cost. In addition,Solitario’s policy is to recognize revenue on any receipts of joint venture property payments in excess of its capitalized costs on a property that Solitario may lease to another miningcompany. 9 Solitario has not recognized any revenue during 2022 or 2021. Solitario expects any property sales in the future to be on an infrequent basis. Solitario last recognized revenue in2019 from the sale of certain royalties and in 2018 from the sale of its royalty in the Yanacocha property. Solitario does not expect to record joint venture property payments on any of itscurrently held properties for the foreseeable future. Historically, Solitario’s revenues have been infrequent and significant individual transactions have only been from sales to wellknown or vetted mining companies. Solitario has never had a return on any of its sales recorded as revenue in its history and does not anticipate it will recognize any estimated returnson any potential future recorded revenues. Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect thereported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expensesduring the reporting period. Actual results could differ from those estimates. Some of the more significant estimates included in the preparation of Solitario's financial statements pertainto: (i) the recoverability of its investment in mineral properties related to its mineral exploration properties and their future exploration potential; (ii) the fair value of stock option grants toemployees; (iii) the ability of Solitario to realize its deferred tax assets; and (iv) Solitario's investment in marketable equity securities. In performing its activities, Solitario has incurred certain costs for mineral properties. The recovery of these costs is ultimately dependent upon the sale of mineral propertyinterests or the development of economically recoverable mineral reserves and the ability of Solitario to obtain the necessary permits and financing to successfully place the propertiesinto production, and upon future profitable operations, none of which is assured. Cash and cash equivalents Cash equivalents include investments in highly liquid moneymarket securities with original maturities of three months or less when purchased. At December 31, 2022,approximately $293,000 of Solitario’s cash and cash equivalents are held in brokerage accounts and foreign banks, which are not covered under the Federal Deposit InsuranceCorporation (“FDIC”) rules for the United States. Shortterm investments At December 31, 2022, Solitario has United States Treasury securities (“USTS”) with maturities of 15 days to one year, recorded at their fair value of $3,951,000 compared toUSTS recorded at their fair value of $4,236,000 at December 31, 2021. At December 31, 2021, Solitario also held FDIC insured bank certificates of deposit (“CD’s”) with face valuesbetween $100,000 and $250,000 and maturities of three months to one year, which are recorded at their fair value of $851,000. Solitario’s shortterm investments are recorded at their fairvalue based upon quoted market prices. During the year ended December 31, 2022 and 2021 the noncash decrease in the fair value of its shortterm investments, due primarily tochanges in interest rates on held securities, was $108,000 and $102,000, respectively. The shortterm investments are highly liquid and may be sold in their entirety at any time at theirquoted market price and are classified as a current asset. Mineral properties Solitario expenses all exploration costs incurred on its mineral properties prior to the establishment of proven and probable reserves through the completion of a feasibilitystudy. Initial acquisition costs of its mineral properties are capitalized. Solitario regularly performs evaluations of its investment in mineral properties to assess the recoverability and/orthe residual value of its investments in these assets. All longlived assets are reviewed for impairment whenever events or circumstances change which indicate the carrying amount ofan asset may not be recoverable, utilizing established guidelines based upon undiscounted future net cash flows from the asset or upon the determination that certain explorationproperties do not have sufficient potential for economic mineralization. Derivative instruments Solitario accounts for its derivative instruments in accordance with ASC 815, "Accounting for Derivative Instruments and Hedging Activities" (“ASC 815”). During 2019,Solitario acquired certain Vendetta Mining Corp. (“Vendetta”) units, which included Vendetta Warrants (defined below). Changes in fair value of the Vendetta Warrants are recognizedin the statements of operations in the period of change as gain or loss on derivative instruments. Solitario has entered into covered calls from time to time on its investment in KinrossGold Corporation (“Kinross”) marketable equity securities. Solitario has not designated its covered calls as hedging instruments and any changes in the fair value of the covered callsare recognized in the statements of operations in the period of the change as gain or loss on derivative instruments. 10 Fair value Financial Accounting Standards Board ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”) establishes a framework for measuring fair value and requiresenhanced disclosures about fair value measurements. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer aliability in an orderly transaction between market participants. Solitario's shortterm investments in USTS and CD’s, its marketable equity securities and any covered call options againstthose marketable equity securities are carried at their estimated fair value based on quoted market prices. See Note 8, “Fair Value of Financial Instruments,” below. Marketable equity securities Solitario's investments in marketable equity securities are carried at fair value, which is based upon quoted prices of the securities owned. Solitario records investments inmarketable equity securities for investments in publicly traded marketable equity securities for which it does not exercise significant control and where Solitario has no representation onthe board of directors of those companies and exercises no control over the management of those companies. The cost and realized gain or loss on marketable equity securities sold isdetermined by the specific identification method. Changes in fair value on Solitario’s holdings of marketable equity securities are recorded as unrealized gain or loss in the consolidatedstatement of operations. Foreign exchange The United States dollar is the functional currency for all of Solitario's foreign subsidiaries. Although Solitario's South American exploration activities during 2022 and 2021were conducted primarily in Peru, a portion of the payments for the land, leasehold and exploration agreements as well as certain exploration activities are denominated in United Statesdollars. Intercompany funding is transacted in United States dollars. Foreign currency gains and losses are included in the results of operations in the period in which they occur. Income taxes Solitario accounts for income taxes in accordance with ASC 740, “Accounting for Income Taxes” (“ASC 740”). Under ASC 740, income taxes are provided for the tax effects oftransactions reported in the financial statements and consist of taxes currently due plus deferred taxes related to certain income and expenses recognized in different periods for financialand 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 whenthe 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 incometaxes, 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. Accounting for uncertainty in income taxes ASC 740 clarifies the accounting for uncertainty in income taxes recognized in a company's financial statements. ASC 740 prescribes a recognition threshold and measurementattribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition,classification, interest and penalties, accounting in interim periods, disclosure, and transition. ASC 740 provides that a company's tax position will be considered settled if the taxingauthority has completed its examination, the company does not plan to appeal, and it is remote that the taxing authority would reexamine the tax position in the future. These provisionsof ASC 740 had no effect on Solitario's financial position or results of operations. See Note 6, “Income Taxes,” below. Earnings per share The calculation of basic and diluted earnings (loss) per share is based on the weighted average number of shares of common stock outstanding during the years endedDecember 31, 2022 and 2021. Potentially dilutive shares, consisting of outstanding common stock options of 5,390,000 and 5,513,000, respectively, exercisable for Solitario commonshares were excluded from the calculation of diluted loss per share for the year ended December 31, 2022 and 2021 because the effects were antidilutive. 11 Employee stock compensation and incentive plans Solitario classifies all of its stock options as equity options in accordance with the provisions of ASC 718, “Compensation – Stock Compensation.” See Note 10, “EmployeeStock Compensation Plans,” below. Risks and Uncertainties Solitario faces risks related to health epidemics and other outbreaks of communicable diseases, which could significantly disrupt its operations and may materially andadversely affect its business and financial conditions. Solitario’s business still could be adversely impacted by the effects of the coronavirus (“COVID19”) or other epidemics or pandemics. Solitario continues to evaluate theeffects of COVID19 on its operations and at times during the pandemic has taken proactive steps to address the impacts on its operations, including at times reducing costs, inresponse to the economic uncertainty associated with potential risks from COVID19. These prior cost reductions included implementing salary reductions and evaluating and reducingcertain planned 2021 exploration programs through its joint venture partners at the Florida Canyon and Lik exploration projects. Certain of Solitario’s joint venture partners have, fromtime to time, modified plans with respect to the projects in which Solitario holds an interest in response to the COVID19 pandemic. Also, Solitairo has evaluated the potential impacts onits ability to access future traditional funding sources on the same or reasonably similar terms as in past periods. Solitario will continue to monitor the effects of COVID19 on itsoperations, financial condition, and liquidity. However, the extent to which COVID19 ultimately impacts Solitario’s business, including its exploration and other activities and the marketfor its securities, will depend on future developments, which are highly uncertain and cannot be predicted at this time, and include the duration, severity and scope of any new outbreakand the actions taken to contain or treat the COVID19 pandemic. 2. Mineral Properties: The following table details Solitario’s capitalized investment in exploration mineral property: (in thousands) December 31, 2022 2021 Exploration Lik project (Alaska – US) $15,611 $15,611 Golden Crest (South Dakota – US) 1,035 695 Total exploration mineral property $16,646 $16,306 Exploration property Solitario's exploration mineral properties at December 31, 2022 and 2021 consist of use rights related to its exploration properties, and the value of such assets is primarily drivenby the nature and amount of economic mineral ore believed to be contained, or potentially contained, in such properties. The amounts capitalized as mineral properties includeconcession and lease or option acquisition costs. Capitalized costs related to a mineral property represent its fair value at the time it was acquired or the cost to acquire the property, asappropriate. At December 31, 2022, none of Solitario’s exploration properties have production (are operating) or contain proven or probable reserves. Solitario's exploration mineralproperties represent interests in properties that Solitario believes have exploration and development potential. Solitario's mineral use rights generally are enforceable regardless ofwhether proven and probable reserves have been established. 12 Golden Crest On May 27, 2021, Solitario entered into a lease agreement (the “Golden Crest Agreement”) whereby Solitario acquired exclusive exploration rights in certain claims (the “GCClaims”) in the Black Hills region of South Dakota. The GC Claims are part of Solitario’s Golden Crest project. Terms of the Golden Crest Agreement include scheduled payments to theunderlying owner of $65,000 paid upon signing and the payment to the underlying owner of $60,000 at the first anniversary date during 2022. Solitario recorded an initial acquisition costof $125,000 during 2021 related to these required payments. In addition, to continue the lease, Solitario has agreed to pay, at its option, the underlying owner escalating annual paymentsover five years that total $340,000 and annual payments of $150,000 thereafter, which will be expensed as paid. Solitario has agreed to pay the underlying owner an additional successfee of $1.00 per ounce of gold in the event Solitario files a 43101 qualified resource of up to 1.5 million ounces of gold or a maximum of $1,500,000. Solitario has agreed to escalating workcommitments, at Solitario’s option, on the GC Claims and an area of interest around the GC claims totaling $3,000,000 during the first five years of the lease, with the firstyear minimumexploration expenditures of $200,000, which Solitario exceeded during 2022. The term of the Golden Crest Agreement is for twenty years and is automatically extended as long as Solitariois performing any exploration, development or mining activities on the GC Claims. The underlying owner retained a 2.0% Net Smelter Return royalty. Solitario will have the option, butnot the obligation, to reduce the Net Smelter Return royalty to 1.0% by paying the owner $1,000,000. In addition, through December 31, 2022, Solitario has staked additional mineral claims, including some claims included in an area of interest of the GC Claims and claims notrelated to the GC Claims, as part of the Golden Crest project. As of December 31, 2022 and 2021 Solitario has capitalized costs for staking, initial filing fees, legal and other costs of$1,035,000 and $695,000 as initial acquisition costs related to the Golden Crest project. Lik Property Solitario holds a 50% operating interest in the Lik zinclead sliver property in northwest Alaska, which we acquired as part of the acquisition of Zazu Metals Corporation(“Zazu”) in July 2017. Solitario recorded its acquisition cost of $15,611,000 as mineral property at the date of acquisition. Teck is Solitario’s 50% partner on the Lik Project and acted asthe project manager during 2022 and 2021. Florida Canyon In addition to its capitalized exploration properties, Solitario has an interest in its Florida Canyon exploration concessions, which are currently subject to a joint ventureagreement where joint venture partners made standby joint venture payments to Solitario prior to January 1, 2015. Solitario previously recorded joint venture property payment revenuereceived in excess of capitalized costs. Per the joint venture agreement, as of December 31, 2022, no further standby jointventure payments are due to Solitario on the Florida Canyonproject. At December 31, 2022 and 2021, Solitario has no remaining capitalized costs related to its Florida Canyon joint venture. Per the joint venture agreement with Nexa covering theFlorida Canyon project, Solitario currently holds a 39% interest in the Florida Canyon zinc project. Nexa is required to fund 100% of exploration expenditures at Florida Canyon, untilNexa commits to put the project into production based upon a positive feasibility study, at which time Nexa’s interest will increase from its current 61% interest to a 70% interest. Discontinued projects During 2021 Solitario recorded $17,000 of mineral property impairment related to its decision to abandon its Gold Coin project in Arizona. Solitario did not record any mineralproperty impairments during 2022. Exploration Expense The following items comprised exploration expense: For the year endedDecember 31, (in thousands) 2022 2021 Geologic and field expenses $2,121 $1,092 Administrative 162 106 Total exploration expense $2,283 $1,198 Asset Retirement Obligation Solitario recorded an asset retirement obligation of $125,000 for Solitario’s estimated reclamation cost of the existing disturbance at the Lik project. This disturbance consists ofan 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 jointventure 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 orits 50% partner, Teck, do not complete required reclamation. 13 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 reclamation is notexpected to occur until the end of the Lik 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 December 31, 2022, Solitario has no reclamation liability at its Florida Canyon project as Nexa is responsible for the costs at Florida Canyon, including reclamation, if any.In addition, the activities to date at Solitario’s Golden Crest project of staking claims and mapping, soil and rock sampling, and assaying have not created any material environmental orother disturbances. Historically Solitario’s exploration activities have not resulted in any longterm environmental disturbances or liabilities and where there have been requiredrestoration of disturbances, these have been completed contemporaneously with the completion of our mineral exploration activities. 3. Marketable Equity Securities During 2022 Solitario sold 1,250,000 shares of Vendetta common stock for proceeds of $63,000 and recorded a realized loss on sale of $201,000. During 2021, Solitario sold (i)2,550,000 shares of Vendetta common stock for proceeds of $112,000 and recorded a realized loss on the sale of $269,000; (ii) 430,000 shares of TNR Gold Corp.

(“Vox”) common stock for proceeds of $8,000 and recorded arealized gain on the sale of $2,000. On July 31, 2019, Solitario purchased 3,450,000 Vendetta units for aggregate consideration of $233,000. Each unit consisted of one share of Vendetta common stock and onewarrant which allows the holder to purchase one additional share of Vendetta common stock at a purchase price of Cdn$0.13 per share for a period of three years (the “VendettaWarrants”). The Vendetta Warrants expired unexercised during 2022. During 2022 and 2021, Solitario recorded a loss on derivative instruments of $4,000 and $46,000, respectively, for thechange in the value of the Vendetta Warrants. At December 31, 2022 Solitario owns the following marketable equity securities: Year endedDecember 31, 2022 Year endedDecember 31, 2021 shares Fair value(000’s) shares Fair value(000’s) Kinross Gold Corp 100,000 $409 100,000 $581 Vendetta Mining Corp. 7,750,000 229 9,000,000 356 Vox Royalty Corp. 134,055 311 134,055 370 Highland Silver Corp. 200,000 Total $949 $1,307 The following tables summarize Solitario’s marketable equity securities and adjustments to fair value:(in thousands) Year endedDecember 31, 2022 2021 Marketable equity securities at cost $1,440 $1,704 Cumulative unrealized loss on marketable equity securities (491) (397)Marketable equity securities at fair value $949 $1,307 The following table represents changes in marketable equity securities:(in thousands) Year endedDecember 31, 2022 2021 Cost of marketable equity securities sold $264 $395 Realized loss on marketable equity securities sold (201) (248)Proceeds from the sale of marketable equity securities sold (63) (147)Net loss on marketable equity securities (295) (166)Additions to marketable equity securities Change in marketable equity securities at fair value $(358) $(313) 14 The following table represents the realized and unrealized gain (loss) on marketable equity securities: (in thousands) Year endedDecember 31, 2022 2021 Unrealized (loss) gain on marketable equity securities $(94) $82 Realized loss on marketable equity securities sold (201) (248)Net loss on marketable equity securities $(295) $(166) Other Income During 2022, Solitario sold rights to certain exploration data on a nonowned mineral property upon which Solitario had previously done exploration activities. The data was soldto Highland Silver Corp., a Canadian exploration company (“Highland”) for $20,000 cash and 200,000 shares of Highland common stock. On the date of sale, the Highland common stockcarried a restrictive legend. The shares were not available for trade on the date of sale and at December 31, 2022 and no value has been assigned to the common stock. Solitario recorded$20,000 of other income on the date of the sale. Any future changes to the value of the Highland common stock owned by Solitario will be recorded as changes in value of marketableequity securities. 4. Operating Lease Solitario accounts for its leases in accordance with ASC 842. Solitario leases one facility, its Wheat Ridge, Colorado administrative office (the “WR Lease”), that has a term ofmore than one year. Solitario has no other significant operating lease costs. The WR Lease was extended to October 2023 during 2021 and Solitario recorded a net increase in right of useassets of $99,000 during 2021 upon the extension of the WR Lease. The WR Lease is classified as an operating lease and has a remaining term of 10 months at December 31, 2022. Therightofuse office lease asset for the WR Lease is classified as other assets and the related liability as a current office lease liability in the consolidated balance sheet. Lease expense isrecognized on a straightline basis over the lease term, with variable lease payments recognized in the period those payments are incurred. During 2022 and 2021, Solitario recognized $40,000 and $40,000, respectively, of noncash lease expense for the WR Lease included in general and administrative expense. Cashlease payments of $39,000 and $39,000, respectively, were made on the WR Lease during 2022 and 2021 and this amount, less $3,000 and $4,000, respectively, of imputed interest during2022 and 2021, reduced the related liability on the WR Lease. The discount rate within the WR Lease is not determinable and Solitario applied a discount rate of 5% based uponSolitario’s estimate of its cost of capital in recording the WR Lease. Solitario has $36,000 remaining cash payments as of December 31, 2022. The following is supplemental cash flow information related to our operating lease for 2022 and 2021: (in thousands) Year endedDecember 31,2022 Year endedDecember 31,2021 Cash paid for amounts included in the measurement of lease liabilities Operating cash outflows from WR Lease payments $39 $39 Noncash amounts related to the WR lease Right of use assets recorded in exchange for new operating lease liabilities $ $99 5.

Income Taxes: Consolidated loss before income taxes includes losses from foreign operations of $37,000 and $136,000 in 2022 and 2021, respectively. The net deferred tax assets/liabilities in the December 31, 2022 and 2021 consolidated balance sheets include the following components: (in thousands) 2022 2021 Deferred tax assets: Loss carryovers $11,652 $12,148 Investment in Mineral Property 1,669 1,669 Capitalized Exploration Costs 778 418 Stock option compensation expense 152 309 Unrealized loss on derivative securities 121 98 Other 65 91 Unrealized loss on shortterm investments 20 Lease Liability 9 18 Valuation allowance (14,309) (14,561)Total deferred tax assets 157 190 Deferred tax liabilities: Unrealized gains on marketable equity securities 149 173 Lease Asset 8 17 Total deferred tax liabilities 157 190 Net deferred tax liabilities $ $ A reconciliation of expected federal income taxes on income (loss) from continuing operations at statutory rates, with the expense for income taxes is as follows: (in thousands) 2022 2021 Expected income tax benefit $(825) $(497)Equity based compensation 238 4 Foreign tax rate differences (3) (12)State income tax (166) (98)Expiration of Capital Loss and Foreign Tax Credit Carryovers 18 1,385 Adjustment to Deferred Taxes 11 (82)Foreign currency exchange 968 (32)Change in valuation allowance (251) (489)Change in Tax Rates 13 (194)Permanent differences and other (3) 15 Income tax (benefit) expense $ $ During 2022, the valuation allowance increased primarily due to the addition of deferred tax assets related to current year net operating losses. During 2021, the valuationallowance decreased primarily due to the expiration of capital loss carryovers. At December 31, 2022, Solitario has unused US Federal net operating loss carryovers of $22,905,000 and unused US State net operating loss carryovers of $24,811,000 whichbegin expiring in 2027. As a result of the ownership change of Zazu Metals (Alaska) Corp, utilization of some of these federal and state losses will be limited due to the annual limitationprovided by Section 382 of the Internal Revenue Code. Solitario has unused capital loss carryovers of $380,000 for US Federal and US State purposes which begin expiring in 2025.Solitario has Canadian loss carryforwards of $9,294,000 which begin expiring in 2027. Other foreign loss carryforwards for which Solitario has provided a full valuation allowance relatedto Solitario’s exploration activities in Peru. The Peru losses do not expire. 16 Solitario adopted ASC 740, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position takenor expected to be taken in a tax return. ASC 740 requires that Solitario recognize in its consolidated financial statements only those tax positions that are “morelikelythannot” of beingsustained as of the adoption date, based on the technical merits of the position. As a result of the implementation of ASC 740, Solitario performed a comprehensive review of its materialtax positions in accordance with recognition and measurement standards established by ASC 740. The provisions of ASC 740 had no effect on Solitario’s financial position, cash flowsor results of operations at December 31, 2022 or December 31, 2021, or for the years then ended as Solitario had no unrecognized tax benefits. Solitario and its subsidiaries are subject to the following material taxing jurisdictions: United States Federal, State of Colorado, State of Alaska, State of South Dakota, Canadaand Peru. Solitario’s United States federal, Canada and State of Alaska returns for years 2019 and forward and Solitario’s Peru and State of Colorado returns for tax years 2018 andforward are subject to examination. Solitario’s policy is to recognize interest and penalties related to uncertain tax benefits in income tax expense. Solitario has no accrued interest orpenalties related to uncertain tax positions as of December 31, 2022, or December 31, 2021 or for the years then ended. 7. Derivative Instruments: Covered call options From timetotime Solitario has sold covered call options against its holdings of shares of common stock of Kinross included in Marketable Equity Securities. The businesspurpose of selling covered calls is 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 thanone 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. During 2021, Solitario sold covered calls againstits holdings of Kinross for cash proceeds of $8,000 all of which expired unexercised. As of December 31, 2022 and 2021, Solitario has no remaining liability related to Kinross calloptions. 8. Fair Value of Financial Instruments: For certain of Solitario's financial instruments, including cash and cash equivalents, payables and shortterm debt, the carrying amounts approximate fair value due to their shortmaturities. Solitario's marketable equity securities, including its investment in shares of Kinross common stock, Vendetta common stock, Vox common stock and TNR common stock arecarried at their estimated fair value based on publicly available quoted market prices. Solitario applies ASC 820 that establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. ASC 820 clarifies that fairvalue is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820 alsorequires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy for which these assets and liabilities must be grouped, based on significantlevels of inputs as follows: Level 1: Quoted prices in active markets for identical assets or liabilities;Level 2: Quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; orLevel 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. During theyears ended December 31, 2022 and 2021, there were no reclassifications in financial assets or liabilities between Level 1, 2 or 3 categories. 17 The following is a listing of Solitario’s financial assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchyas of December 31, 2022: (in thousands) Level 1 Level 2 Level 3 Total Assets Shortterm investments $3,951 $ $ $3,951 Marketable equity securities $949 $ $ $949 The following is a listing of Solitario’s financial assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchyas of December 31, 2021: (in thousands) Level 1 Level 2 Level 3 Total Assets Shortterm investments $5,087 $ $ $5,087 Marketable equity securities $1,307 $ $ $1,307 Vendetta Warrants $ $3 $ $3 Items measured at fair value on a recurring basis: Shortterm investments: At December 31, 2022 and 2021, Solitario’s holdings of shortterm investments consist of USTS and CD’s at December 31, 2021, both recorded at their fair valuebased upon quoted market prices.Marketable equity securities: At December 31, 2022 and 2021, the fair value of Solitario’s holdings in shares of Vendetta, Kinross, and Vox marketable equity securities are based uponquoted market prices.Vendetta Warrants: At December 31, 2021 the fair value of Solitario’s Vendetta Warrants is based upon a Black Scholes model, using market inputs. During the year ended December 31, 2022, Solitario did not change any of the valuation techniques used to measure its financial assets and liabilities at fair value. 9. Commitments and Contingencies: In acquiring its interests in mineral claims and leases, Solitario has entered into lease agreements, which may be canceled at its option without penalty. Solitario is required tomake minimum rental and option payments in order to maintain its interests in certain claims and leases. See Note 2, “Mineral Properties,” above. Solitario estimates its 2023 propertyclaim, lease and option payments for properties Solitario owns, has under joint venture or Solitario operates to be approximately $1,274,000. Assuming that Solitario’s joint venturescontinue in their current status and that Solitario does not appreciably change its property positions on existing properties, approximately $419,000 of these estimated 2023 propertyclaim, lease and rental payments are paid or are reimbursable to us by Solitario’s joint venture partners. Solitario may be required to make further payments in the future if it acquires newproperties or enters into new agreements. 10. Employee Stock Compensation Plans: On June 18, 2013, Solitario’s shareholders approved the Solitario Exploration & Royalty Corp. Omnibus Stock Incentive Plan (the “2013 Plan”). Under the terms of the 2013 Plan,as amended, a total of 5,750,000 shares of Solitario common stock are reserved for awards to directors, officers, employees and consultants.

Wainwright & Co., LLC (“Wainwright”), under whichSolitario may, from time to time, issue and sell shares of Solitario’s common stock through Wainwright as sales manager in an atthemarket offering under a prospectus supplement foraggregate sales proceeds of up to $9.0 million (the “ATM Program”). The common stock is distributed at the market prices prevailing at the time of sale. As a result, prices of thecommon stock sold under the ATM Program may vary as between purchasers and during the period of distribution.
