1.       Business and Significant Accounting Policies
 
Business and company formation
 
Solitario Zinc Corp. (“Solitario,” or the “Company”) is an exploration stage company as defined in Industry Guide 7, asby 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 ("Crown"). In July 1994, Solitario became 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 its own 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 their development 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 the property. Solitario is primarily focused on the acquisition and exploration of zinc-related exploration mineral properties; however, Solitario will evaluate and acquire other base and precious metal mineral exploration properties. In addition to focusing on its mineral exploration properties and the evaluation of mineral properties for acquisition, Solitario also 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 to Solitario.
 
Solitario has recorded revenue in the past from the sale of mineral property,properties, including (i) the sale of (i) certain mineral royalty properties to SilverStream SEZC, a private Cayman Island royalty and streaming company (“SilverStream”) for Cdn$600,000 in January 2019 (the “Royalty Sale”), and (ii) the sale in June 2018 of its interest in the royalty on its Yanacocha property. In addition, Solitario has received proceeds from (i) the sale in 2015 of its former interest in Mount Hamilton LLC (“MH-LLC”), the owner of its former Mt. Hamilton project; (ii) the sale of a royalty on its former Mt. Hamilton projectproperty and (iii) joint venture property payments. Revenues and / or proceeds from the sale or joint venture of properties or assets, although 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 project in Peru and its interest in the Lik project in Alaska to be its core mineral property assets. Nexa Resources, Ltd. (“Nexa”), Solitario’s joint venture partner, is expected to continue the exploration and furtherance of the Florida Canyon project and Solitario is monitoring progress at Florida Canyon. Solitario is working with its 50% joint venture partner in the Lik deposit, 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.
 
As of March 31, 2020,2021, Solitario has significant balances of cash and short-term investments that Solitario anticipates using, in part, to fund costs and activities intended to further the exploration of the Florida Canyon, Lik and LikGold Coin 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 months ended March 31, 20202021 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. Interim results are not necessarily indicative of results, which may be achieved in the future or for the full year ending December 31, 2020.2021.
 
These financial statements should be read in conjunction with the financial statements and notes thereto which are included in Solitario’s Annual Report on Form 10-K for the year ended December 31, 2019.2020. The accounting policies set forth in those annual financial statements are the same as the accounting policies utilized in the preparation of these financial statements, except as modified for appropriate interim financial statement presentation.
 

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 and adversely affect ourits business and financial conditions.
 
Solitario’s business could be adversely impacted by the effects of the coronavirus (COVID-19)(“COVID-19”) or other epidemics or pandemics. TheSolitario has recommended all of its employees and contractors follow government guidelines for health and safety policies for employees and contractors, including encouraging tele-commuting and working from home where possible. Solitario has evaluated the effects of COVID-19 on its operations and taken pro-active steps to address the impacts on its operations, including reducing costs, in response to the economic uncertainty associated with potential risks from COVID-19. Also, Solitairo has evaluated the potential impacts on its 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 COVID-19 on its operations, financial condition and liquidity. However, the extent to which the coronavirusCOVID-19 impacts Solitario’s business, including our exploration and other activities and the market for itsour 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 the outbreak and the actions taken to contain or treat the coronavirus outbreak. Solitario has taken steps to conserve its financial resources including reducing costs, in response to the economic uncertainty associated with these risks. See Item 1A “Risk Factors” below.

Financial reporting
The 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 consolidated financial statements are prepared in accordance with generally accepted accounting principles and are expressed in U.S. 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 its exploration mineral properties (those without reserves) on a property by property 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 mining company.
Solitario has recognized revenue during the three months ended March 31, 2019 of $408,000 related to the Royalty Sale in accordance with Accounting Standards Codification (“ASC”) 606. Solitario expects any property, royalty or asset sales in the future to be on an infrequent basis. Solitario does not expect to record joint venture property payments on any of its currently held properties for the foreseeable future. Historically, Solitario’s revenues have been infrequent and significant individual transactions and have only been from sales to well known 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 returns on its current or 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 the reported 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 expenses during 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 pertain to: (i) the recoverability of mineral properties related to its mineral exploration properties and their future exploration potential; (ii) the fair value of stock option grants to employees; (iii) the ability of Solitario to realize its deferred tax assets; (iv) Solitario's investment in marketable equity securities; and (v) the collectability of the SilverStream Note (as defined below).
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 property interests or the development of economically recoverable ore reserves and the ability of Solitario or its joint venture partners to obtain the necessary permits and financing to successfully place the properties into production, and upon future profitable operations, none of which is assured.
 
Cash equivalents
 
Cash equivalents include investments in highly liquid money-market securities with original maturities of three months or less when purchased. As of March 31, 2020, $425,0002021, $1,389,000 of Solitario’s cash and cash equivalents are held in brokerage accounts and foreign banks, which are not covered under the Federal Deposit Insurance Corporation (“FDIC”) rules for the United States.
 
Short-term investments
 
As of March 31, 2020,2021, Solitario has $6,325,000$3,529,000 of its current assets in United States Treasury Securities (“USTS”) with maturities of 15 days to 159 months. In addition, at March 31, 2021, Solitario has twosix bank certificates of deposits (“CD’s”) each with a face values between $250,000 and $100,000 recorded at their total fair value of $250,000.$1,306,000. The CD’s have maturities of one month to one year. The USTS and CD’s are recorded at their fair value, based upon quoted market prices. The USTS are not covered under the FDIC insurance rules for United States deposits. Solitario’s USTS and CD’s are highly liquid and may be sold in their entirety at any time at their quoted 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 feasibility study. Initial acquisition costs of its mineral properties are capitalized. Solitario regularly performs evaluations of its investment in mineral properties to assess the recoverability and/or the residual value of its 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 established guidelines based upon undiscounted future net cash flows from the asset or upon the determination that certain exploration properties do not have sufficient potential for economic mineralization.

Leases
Solitario accounts for its leases in accordance with ASC 842,Leases(“ASC 842”) by recognizing right-of-use assets and lease liabilities on the condensed consolidated balance sheet and disclosing key information about lease arrangements. Solitario has elected the practical expedient option to use January 1, 2019, the effective date of adoption of ASC 842, as the initial date of transition and not to restate comparative prior periods and to carry forward historical lease classification. In addition, Solitario has elected the option not to apply the recognition of assets and liabilities provisions of ASC 842 to operating leases with initial terms of less than one year. See Note 4 “Operating Leases” for more information and disclosures regarding Solitario’s leases.
Derivative instruments
Solitario accounts for its derivative instruments in accordance with ASC 815.  Solitario has entered into covered calls from time to time on its investment in Kinross Gold 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 calls are recognized in the statement of operations in the period of the change as gain or loss on derivative instruments, and as a change to operating activities in the statement of cash flows for the non-cash portion of the gain or loss.
Fair value
ASC 820 established a framework for measuring fair value of financial instruments and required disclosures about fair value measurements. For certain of Solitario's financial instruments, including cash and cash equivalents and accounts payable, the carrying amounts approximate fair value due to their short-term maturities. Solitario's short-term investments in USTS and CD’s, its marketable equity securities and any covered call options against those marketable equity securities are carried at their estimated fair value based on quoted market prices. See Note 6, “Fair Value,” 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 in marketable equity securities for investments in publicly traded marketable equity securities for which it does not exercise significant control and where Solitario has no representation on the board of directors of those companies and exercises no control over the management of those companies. The cost of marketable equity securities sold is determined by the specific identification method. Changes in fair value are recorded as unrealized gain or loss in the condensed consolidated statement 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 2019 and the first quarter of 2020 were conducted primarily in Peru, a portion of the payments under land, leasehold and exploration agreements of Solitario are denominated in United States dollars. Realized 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 of transactions 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 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.
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 measurement attribute 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 taxing authority 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.

Earnings per share

Asset Retirement Obligation
 
In connection with the acquisition of its interest in the Lik project in 2017, 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 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 the permitting bond required by the State of Alaska, for which Solitario has purchased a reclamation bond insurance policy in the event Solitario or its 50% partner, 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 reclamation is not expected 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.

8.        Income Taxes
 
Solitario accounts for income taxes in accordance with ASC 740. Under ASC 740, income taxes are provided for the tax effects of transactions 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 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 March 31, 20202021 and December 31, 2019,2020, 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 months ended March 31, 20202021 and 2019,2020, Solitario recorded no deferred tax expense.

At the Market Offering Agreement
On February 2, 2021, Solitario entered into an at-the-market offering agreement (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 $9.0 million (the “ATM Program”).   The common stock will be 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 as between purchasers and during the period of distribution. The ATM Agreement provides that Wainwright will be 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 months ended March 31, 2021, Solitario recorded $79,000 as a charge to additional paid-in-capital for one-time expenses related to entering into the ATM Agreement.

During the three months ended March 31, 2021, Solitario sold an aggregate of 150,400 shares of common stock under the ATM Agreement at an average price of $1.21 per share for net proceeds of $177,000 after commissions and sale expenses.  
 
Share Repurchase Program
 
On October 28, 2015, Solitario’s Board of Directors approved a share repurchase program that authorized Solitario to purchase up to two million shares of its outstanding common stock. During 2019,2020, Solitario’s Board of Directors extended the expiration date of the share repurchase program through December 31, 2020.2021. Solitario did not purchase any shares under the share repurchase plan during the three months ended March 31, 2021. During the three months ended March 31, 2020 and 2019, Solitario purchased 16,700 and 27,900 shares of Solitario common stock respectively, for an aggregate purchase price of $3,000 and $9,000, respectively.$3,000. As of March 31, 2020,2021, Solitario has purchased a total of 986,000994,000 shares for an aggregate purchase price of $465,000$467,000 under the share repurchase program since its inception.

11.        Subsequent Event
In April 2020, in response to significant market volatility and uncertainty and the resulting need for Solitario to conserve its financial resources, Solitario applied for and received a loan in the amount of $70,000 (the “PPP Loan”) pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) to help fund Company payroll, rent and utilities obligations. The PPP Loan has a two-year term and bears interest at a rate of 1.0% per annum. Monthly principal and interest payments are deferred for six months after the date of disbursement. The PPP Loan may be prepaid at any time prior to maturity, under certain conditions, with no prepayment penalties. The Promissory Note contains events of default and other provisions customary for a loan of this type. The Paycheck Protection Program provides that the PPP Loan may be partially or wholly forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. Solitario intends to use the proceeds from the PPP Loan for qualifying expenses and to apply for forgiveness of the PPP Loan in accordance with the terms of the CARES Act. However, Solitario cannot completely assure at this time that such forgiveness of the PPP Loan will occur.
 
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, 20192020 and 2018,2019, and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Solitario’s Annual Report on Form 10-K as amended, for the year ended December 31, 2019.2020. Solitario's financial condition and results of operations 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 under Industry Guide 7, 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 acquisition and exploration of zinc-related exploration mineral properties. However, we will 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, we also from time to time 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 March 31, 2020,2021, we consider 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, at March 31, 2020,2021, we have an interest in one exploration property in Peru.Arizona. We are conducting independent exploration activities in Peru and the United States both on our own and through joint ventures operated by our partners in Peru and the United States.States, respectively. We also conduct potential acquisition evaluations in other countries located in South and North America.
 
We have recorded revenue in the past from the sale of mineral properties, including from the Royalty Sale in January 2019 and the sale in June 2018 of our interest in the royalty on the Yanacocha property. 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 venture funding for 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 March 31, 2020,2021, 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 theour Lik project, (ii) fund costs and activities intended to further the exploration at theour Florida Canyon project, (iii) fund costs and activities to further our Gold Coin project; (iv) conduct reconnaissance exploration and (iv)(v) potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices contribute to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of advanced mineral exploration projects or other related assets at potentially attractive terms.
 

As of March 31, 2020,2021, we do not expect the effects of the COVID-19 virusto have not had a material effect on Solitario’s planned activities related to the exploration of its Lik and Florida Canyon projects. However, going forward for the remainder of 2020,2021, we will continue to monitor planned activities for the full year 20202021 at both Florida Canyon, Lik and Lik.our Gold Coin project. The extent to which the coronavirusCOVID-19 impacts our business, including our exploration and other activities and the market for our securities, will depend on future developments, which are highly uncertain and cannot be predicted at this time. Please see Item 1A, “Risk Factors,” below.

in our Annual Report on Form 10-K for the year ended December 31, 2020.
 
 (b) Results of Operations
 
Comparison of the quarter ended March 31, 20202021 to the quarter ended March 31, 20192020.
 
We had a net loss of $528,000 or $0.01 per basic and diluted share for the three months ended March 31, 2021 compared to a net loss of $607,000 or $0.01 per basic and diluted share for the three months ended March 31, 2020 compared to a net loss of $441,000 or $0.01 per basic and diluted share for the three months ended March 31, 2019.2020. As explained in more detail below, the primary reasons for the increasedecrease in the net loss in the three months ended March 31, 20202021 compared to the loss in the first three months of 2019ended March 31, 2020 were (i) the Royalty Sale revenue, net, of $408,000a decrease in general and administrative costs to $280,000 during the three months ended March 31, 2019 with no similar mineral property revenue2021 compared to general and administrative costs of $336,000 during the three months ended March 31, 2020 and2020; (ii) other income of $10,000 from the cancellation of the PPP Loan during the three months ended March 31, 2021, with no similar item in the three months ended March 31, 2020; (iii) a reduction in the loss on derivative instruments to $3,000 during the three months ended March 31, 2021 compared a loss on derivative instruments of $25,000 during the three months ended March 31, 2020, with no similar2020; and (iv) a reduction in the unrealized loss inon marketable equity securities to $122,000 during the three months ended March 31, 2019.2021 compared to an unrealized loss on marketable equity securities of $233,000 during the three months ended March 31, 2020. Partially offsetting the above items were (i) a reductionan increase in exploration expense to $147,000 during the three months ended March 31, 2021 compared to exploration expense of $113,000 during the three months ended March 31, 2020 compared2020; (ii) a reduction in interest income to exploration expense of $163,000$6,000 during the three months ended March 31, 2019; (ii) a reduction in general and administrative expense to $336,000 during the three months ended March 31, 20202021 compared to general and administrative expense of $425,000 during the three months ended March 31, 2019; (iii) an increase in interest income toof $81,000 during the three months ended March 31, 2020 compared2020; and (iii) a reduction in the realized gain on the sale of marketable equity securities to interest income of $72,000$13,000 during the three months ended March 31, 2019; (iv) a reduction in the non-cash loss on unrealized loss on marketable equity securities to $233,000 during the three months ended March 31, 20202021 compared to a non-cash unrealized loss on marketable equity securities of $326,000 during the three months ended March 31, 2019 and (v) arealized gain on sale of marketable equity securities of $25,000 during the three months ended March 31, 2020 with no similar gain during the three months ended March 31, 2019.2020. Each of the major components of these items is discussed in more detail below.
 
          During the three months ended March 31, 2019, we completed the Royalty Sale, discussed above in Note 2 “Mineral Property,” in the condensed consolidated financial statements, and recorded net revenues of $408,000. We received $185,000 in cash and the SilverStream Note for $263,000, less our capitalized cost of $40,000 for the royalties sold. There were no similar itemsOur exploration expense increased to $147,000 during the three months ended March 31, 2020.
Our net2021 compared to exploration expense decreased toof $113,000 during the three months ended March 31, 20202020. The increase was primarily as a result of (i) an increase in expenses to $50,000 related to our Florida Canyon project in Peru, when we substantially completed a 43-101 resource update, which we reported subsequent to March 31, 2021, compared to exploration expenseFlorida Canyon project costs of $163,000$2,000 during the three months ended March 31, 20192020; and (ii) we performed certain initial exploration evaluation expenses of $9,000 during the three months ended March 31, 2021 at our Gold Coin project in Arizona, which we acquired during the fourth quarter of 2020, with no comparable expense during the first quarter of 2020. These increased expenditures were offset by a slight reduction in reconnaissance exploration expenses to $87,000 during the three months ended March 31, 2021 compared to reconnaissance exploration expenses of $105,000 during the three months ended March 31, 2020. These expenditures are normally lower and more comparable during the first quarter of our fiscal year as a result of (i) a decrease in our reconnaissanceweather limitations. In addition, we had limited exploration activities primarily related to the evaluationcosts of mineral properties and / or entities for potential acquisition or other strategic transactions and (ii) a decrease in our activities$1,000 at our La Promesa project in Peru and Lik project in Alaska during the three months ended March 31, 20202021 compared to certain minimal costs at Lik totaling $6,000 during the three months ended March 31, 2019, when we were carrying out community work at La Promesa and working with our joint venture partner, Teck, on reviews of exploration data at Lik.2020. During the three months ended March 31, 20192021 we had threeone contract geologistsgeologist in Peru, one contract geologist working on our Gold Coin project and our Denver personnel spent a majority of their time on reconnaissance exploration activities described above and related matters. We have budgeted approximately $976,000$1,642,000 for the full-year exploration expenditure for 2020,2021, which includes approximately $528,000$500,000 for Solitario’s share of a joint drilling program with Teck at the Lik project, in Alaska, whichwith the bulk of those expensesexpenditures are planned for the third and fourth quarter of 2020.2021. We expect our full-year exploration expenditures for 20202021 to be belowabove the exploration expenditures for full-year 2019, however these expenditures may be impacted by the effects of the COVID-19 pandemic, as discussed above.2020.

General and administrative costs, excluding stock option compensation costs, discussed below, were $252,000 during the three months ended March 31, 2021 compared to $251,000 during the three months ended March 31, 2020 compared to $337,000 during the three months ended March 31, 2019.2020. The major components of these costs were related to (i) salaries and benefit expense of $83,000$68,000 during the first three months of 2020ended March 31, 2021 compared to salary and benefit costs of $108,000 during the three months ended March 31, 2019, as we reduced staff and taken salary reductions during 2020; (ii) legal and accounting expenditures of $11,000 in the first three months of 2020 compared to $53,000 in the first three months of 2019; (iii) office rent and expenses of $43,000$83,000 during the three months ended March 31, 2020, compareddue to $42,000salary reductions implemented during 2020 and continuing into 2021; (ii) legal and accounting expenditures of $58,000 during the three months ended March 31, 2019;2021, compared to $11,000 during the three months ended March 31, 2020; (iii) office rent and expenses of $20,000 during the three months ended March 31, 2021, compared to $45,000 during the three months ended March 31, 2020; and (iv) travel and shareholder relation costs of $112,000 during the first three months of 2020 compared to $133,000$106,000 during the three months ended March 31, 2019.2021 compared to $112,000 during the three months ended March 31, 2020. We anticipate the full-year general and administrative costs will be lowerhigher for 20202021 compared to 2019.2020.
 
We recorded $85,000$28,000 of stock option expense for the amortization of unvested grant date fair value with a credit to additional paid-in-capital during the three months ended March 31, 20202021 compared to $88,000$85,000 of stock option compensation expense during the three months ended March 31, 2019.2020. The higher costs in 2020 related to the grant date fair value of certain option grants which became fully vested during 2020 and were no longer being amortized during 2021. These non-cash charges for the amortization of grant date fair values are related to the expense for vesting onof stock options outstanding during the three months ended March 31, 20202021 and 2019.2020. See Note 9,10, “Employee Stock Compensation Plans,” above, for additional information on our stock option expense.
 
During the three months ended March 31, 2021, we sold various shares of our holdings of marketable equity securities for proceeds of $78,000 and recorded a gain on sale of marketable equity securities of $13,000. During the three months ended March 31, 2020, we sold 2,000,000 shares of our holdings of Vendetta common stock for proceeds of $76,000 and recorded a gain on sale of marketable equity securities of $25,000. After the completion of the sale of the Vendetta shares, we hold 12,450,000 shares of Vendetta common stock. See Note 3 “Marketable Equity Securities” to the condensed consolidated financial statements for a discussion of the sale of Vendetta common stock.

We may sell additional shares of our holdings of marketable equity securities during the remainder of 2021; however, we do not expect sales of marketable equity securities to be a significant source of cash for the year ended December 31, 2021.
 
We recorded an unrealized loss on marketable equity securities of $122,000 during the three months ended March 31, 2021 compared to an unrealized loss on marketable equity securities of $233,000 during the three months ended March 31, 2020 compared to an unrealized loss on marketable equity securities of $326,0002020. The losses during the three months ended March 31, 2019. The loss during the three months ended March 31,2021 and 2020 and 2019 waswere primarily related to a decrease in the value of our holdings, after the sales of 12,450,000marketable equity securities discussed above in Note 3 “Marketable Equity Securities” to the condensed consolidated financial statements, of (i) 100,000 shares of VendettaKinross common stock which decreased from a fair value of $479,000$734,000 at December 31, 20192020 to a fair value of $350,000$667,000 at March 31, 2020 based on quoted market prices. In addition we hold 100,0002021 and (ii) 134,055 shares of Kinross,Vox common stock which decreased from a fair value of $474,000$316,000 at December 31, 20192020 to a fair value of $398,000$256,000 at March 31, 2020,2021 based on quoted market prices, the combination of which accounted for the bulk of the unrealized loss on marketable equity securities during the quarter ended March 31, 2021.
We recorded interest income of $6,000 during the three months ended March 31, 2021 compared to interest income of $81,000 during the three months ended March 31, 2020. This reduction was primarily due to (i) a decrease in the interest earned on our short-term investments in USTS as a result of a decrease in the total amount of outstanding short-term investments during the three months ended March 31, 2021 compared to the three months ended March 31, 2020; (ii) the average interest rates on short term investments decreased during the three months ended March 31, 2020, which increased the value of our existing USTS, recorded as interest income, based upon quoted market prices during the three months ended March 31, 2020, compared to the three months ended March 31, 2021 when average interest rates on short term investments increased slightly, resulting in a reduction in the value of our existing USTS, which was recorded as a reduction in interest income during the three months ended March 31, 2021; and (iii) even with the slight increase in interest rates during the three months ended March 31, 2021, the interest rates during 2021 have been very close to zero on USTS with maturities of a year or less, which compounds the reduction in the amount of interest earned on our lower balance of USTS discussed above.
 
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 stageearly-stage mineral property and its related value for future sale, joint venture or development by us or others. During the three months ended March 31, 20202021 and 2019,2020, we recorded no property impairments.
 
At March 31, 20202021 and 2019,2020, our net operating loss carry-forwards exceed our built-in gains on marketable equity securities resulting in a net tax asset position for which we provide a valuation allowance for all net deferred tax assets. We recorded no income tax expense or benefit during the three months ended March 31, 20202021 or 2019.2020. As a result of our exploration activities, we anticipate we will not have currently payable income taxes during 2020.2021. 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 regards 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.
 

(c) Liquidity and Capital Resources
 
Cash and Short-term Investments
 
As of March 31, 2020,2021, we have $7,269,000had $6,239,000 in cash and short-term investments. As of March 31, 2020,2021, we have $6,325,000had $3,529,000 of our current assets in USTS with maturities of 15 days to 159 months. In addition, as of March 31, 2021 we have twohad six CD’s each with a face values between $250,000 and $100,000, recorded at their total fair value of $250,000.$1,306,000. The USTS and CD’s are recorded at their fair value, based upon quoted market prices. 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 2020.2021.
 
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. We also expect to use a portion of our cash to repurchase shares of our common stock pursuant to the terms of a share repurchase program, discussed above in Note 10, “Shareholders’ Equity,” to the unaudited condensed consolidated financial statements. The share repurchase program may be terminated at any time and does not require Solitario to purchase a minimum number of shares.
 
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 March 31, 20202021, we own 12,450,000owned (i) 10,540,000 shares of Vendetta common stock andwith a fair value of $503,000, (ii) 100,000 shares of Kinross common stock. The Vendetta shares are recorded at their fair market value of $350,000 and the Kinross shares are recorded at their fair value of $398,000 at March 31, 2020. In addition, we own other marketable equity securitiesstock with a fair value of $8,000$667,000, (iii) 134,055 shares of Vox Royalty common stock with a fair value of $256,000 and (iv) 143,000 shares of TNR Gold Corp common stock with a fair value of $7,000. All of our marketable equity securities are carried at March 31, 2020.their fair values based upon quoted market prices. During the three months ended March 31, 2021 and 2020 we sold 2,000,000 sharescertain portions of Vendetta common stock, as discussed above.our marketable equity securities for proceeds of $78,000 and $76,000, respectively and recorded realized gain on sale of marketable equity securities of $13,000 and $25,000, respectively. We anticipate we may sell some of our marketable equity securities during the remainder of 20202021 depending on cash needs and market conditions.
 
Working Capital
 
We had working capital of $7,978,000$7,521,000 at March 31, 20202021 compared to working capital of $8,487,000$7,875,000 as of December 31, 2019.2020. Our working capital at March 31, 20202021 consists primarily of our cash and cash equivalents, our investment in USTS and CD’s, discussed above, our investment in marketable equity securities of $755,000,$1,433,000, and other current assets of $295,000, which include the SilverStream Note of $253,000 at March 31, 2020,$24,000, less our accounts payable of $294,000$137,000 and other current liabilities of $47,000.$38,000. As of March 31, 2020,2021, 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 other exploration projects or assets.
 
Stock-Based Compensation Plans
 
As of both March 31, 2020,2021, and December 31, 20192020 there were options outstanding that are exercisable to acquire 4,373,0005,437,650 and 5,558,000 shares of Solitario common stock. The outstanding options have exercise prices between $0.77$0.20 per share and $0.28$0.77 per share. During the three months ended March 31, 2021, options for 120,350 shares were exercised with an average exercise price of $0.56 per share for proceeds of $67,000. There were no exercises of options under the 2013 Plan during the three months ended March 31, 2020. We do not anticipate the exercise of options to be a significant source of cash flow during the remainder of 2020.2021.
At the Market Offering Agreement
On February 2, 2021, Solitario entered into the ATM Agreement with 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 $9.0 million. During the three months ended March 31, 2021, Solitario sold an aggregate of 150,400 shares of common stock under the ATM Agreement at an average price of $1.21 per share of common stock for net proceeds after commissions and expenses of approximately $177,000.  During the three months ended March 31, 2021, Solitario recorded $79,000 as a charge to additional paid-in-capital for one-time expenses related to entering into the ATM Agreement.
 

 
Share Repurchase Program
 
On October 28, 2015, our Board of Directors approved a share repurchase program that authorized us to purchase up to two million shares of our outstanding common stock. During 2019,2020, our Board of Directors extended the term of the share repurchase program until December 31, 2020.2021. All shares purchased to date have been cancelled and reduced the number of shares of outstanding common stock. The amount and timing of any shares purchased has been determined by our management and the purchases were effected in the open market or in privately negotiated transactions based upon market conditions and other factors, including price, regulatory requirements and capital availability and in compliance with applicable state and federal securities laws. The repurchase program does not require the purchase of any minimum number of shares of common stock by the Company, and may be suspended, modified or discontinued at any time without prior notice. No purchases have been made outside of the United States, including on the TSX. Payments for shares of common stock repurchased under the program have been funded using the Company’s working capital. No shares were repurchased during the three months ended March 31, 2021. As of March 31, 2020,2021, Solitario has purchased a total of 986,000994,000 shares for an aggregate purchase price of $465,000$467,000 under the share repurchase program since its inception and these shares are no longer included in our issued and outstanding shares. Subject to any legal restrictions and our available financial resources, we anticipate we will continue tomay purchase a limited number of shares under the share repurchase plan during 20202021 as determined by management.
 
 (d) Cash Flows
 
Net cash used in operations during the three months ended March 31, 20202021 increased to $238,000$382,000 compared to $172,000$238,000 of net cash used in operations for the three months ended March 31, 20192020 primarily as a result of the mineral property revenue, net, cash received(i) a decrease in interest income during the three months ended March 31, 20192021 to $6,000 compared to interest income of $185,000 from the Royalty Sale, discussed above, with no similar item$81,000 during the three months ended March 31, 2020. This was partially offset by (i)2020, (ii) an increase in exploration expense to $147,000 during the three months ended March 31, 2021 compared to exploration expense of $113,000 during the three months ended March 31, 2020 (iii) a decreaseuse of cash of $26,000 for the reduction of accounts payable and other liabilities during the three months ended March 31, 2021 compared to the provision of cash from an increase in accounts payable and other liabilities of $56,000 during the three months ended March 31, 2020; and (iv) an increase in non-stock option general and administrative expense to $252,000 during the three months ended March 31, 2021 compared to $251,000 during the three months ended March 31, 2020, compared to $337,000 during the three months ended March 31, 2019, discussed above and (iii) a decrease in exploration expenses to $113,000 during the three months ended March 31, 2020 compared to $163,000 during the three months ended March 31, 2019, as a result of a decrease in exploration activities at our La Promesa and Lik projects and a reduction in reconnaissance exploration during 2020 compared to 2019, discussed above. Based upon projected expenditures in our 20202021 budget, we anticipate continued use of funds from operations through the remainder of 2020,2021, primarily for exploration related to our Lik project and reconnaissance exploration. See “Results of Operations” discussed above for further explanation of some of these variances.
 
During the three months ended March 31, 2020,2021, we provided $107,000$1,016,000 in cash from investing activities compared to $602,000$107,000 of cash provided from investing activities during the three months ended March 31, 2019.2020. The primary sources of the cash provided related to the net proceeds from short-term investment sales and purchases of $40,000$938,000 and $602,000,$40,000, respectively, during the three months ended March 31, 20202021 and 2019.2020. In addition, during the three months ended March 31, 2021 and 2020 we sold 2,000,000 shares of Vendetta common stockmarketable equity securities for proceeds of $78,000 and $76,000, with no similar item last year.respectively as discussed above in Note 3, “Marketable Equity Securities” to the condensed consolidated financial statements, above. We may sell additional marketable equity securities during the remainder of 2020,2021, as discussed above. However, we do not anticipate the sale of marketable equity securities will be a significant source of cash during the remainder of 2020.2021. We will continue to liquidate a portion of our short-term investments as needed to fund our operations and orour potential mineral property acquisitions during the remainder of 2020.2021. Any potential mineral property acquisition or strategic corporate investment during the remainder of 2020,2021, discussed above under “Business Overview and Summary,” could involve a significant change in our cash provided or used for investing activities, depending on the structure of any potential transaction.
 
During the three months ended March 31, 2021, we received net cash of $98,000 from the issuance of common stock from the ATM program, discussed above, and we received $67,000 from the issuance of common stock from the exercise of stock options, discussed above in Note 10, “Employee Stock Compensation Plans” to the condensed consolidated financial statements with no comparable amount during the three months ended March 31, 2020. We used $3,000 and $9,000, respectively, for the purchase of our common stock during the three months ended March 31, 2020, and 2019,with no comparable amount during the three months ended March 31, 2021, as discussed above under “Share Repurchase Program” in “Liquidity and Capital Resources.” We anticipate the use of funds for additional purchases of our common stock during the remainder of 2020, however, this will be limited to the maximum number of shares, permissible under the share repurchase program.

Item 4.   Controls and Procedures
 
Disclosure Controls and Procedures
 
As required by Rule 13a-15 under the 1934 Act, as of March 31, 2020,2021, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. This evaluation was carried out under the supervision and with the participation of our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer). Based upon and as of the date of that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2020.2021.
 
Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the 1934 Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the 1934 Act is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Risk Factors
 
Except as detailed below with regard to risks related to the coronavirus pandemic and other potential pandemics,As of March 31, 2021, there were no material changes to the Risk Factors associated with our business disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019.
The outbreak of pandemics, including the coronavirus (COVID-19) may affect our operations
We face risks related to health epidemics and other outbreaks of communicable diseases, which could significantly disrupt our operations and may materially and adversely affect our business and financial conditions.
Our business could be adversely impacted by the effects of the coronavirus (COVID-19) or other epidemics or pandemics. In December 2019, a novel strain of the coronavirus emerged in China and the virus has now spread globally, including the areas we operate in - the western U.S., Alaska, and Peru. The extent to which the coronavirus impacts our business, including our exploration and other activities and the market for our 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 the outbreak and the actions taken to contain or treat the coronavirus outbreak. In particular, the continued spread of the coronavirus and travel and other restrictions established to curb the spread of the coronavirus, could materially and adversely impact our business including without limitation, planned exploration programs at our Florida Canyon and Lik projects during 2020, employee health, workforce productivity, increased insurance premiums, limitations on travel, the availability of industry experts and personnel, the timing to process drill and other metallurgical testing, and other factors that will depend on future developments beyond our control, which may have a material and adverse effect on our business, financial condition and results of operations.
There can be no assurance that our personnel will not be impacted by the coronavirus or other pandemic diseases and that we could ultimately see our workforce productivity reduced or incur increased medical costs or insurance premiums as a result of these health risks. In addition, a significant outbreak of coronavirus could result in a widespread global health crisis that could adversely affect global economies and financial markets resulting in an economic downturn that could have an adverse effect on the demand for precious and base metals and our future prospects.2020.
