Recent developments

Purchase of Zazu

On July 12, 2017,

Business and company formation
Solitario Zinc Corp. (“Solitario”Solitario,” or the “Company”) completed the acquisition of Zazu Metals Corp. (“Zazu”) pursuant to a definitive arrangement agreement between Solitario and Zazu (the "Arrangement Agreement") whereby Solitario agreed to acquire all of the issued and outstanding common shares of Zazu (the "Zazu Shares") by way of a statutory plan of arrangement (the "Arrangement") under theCanada Business Corporations Act (the “Acquisition”). The Arrangement was approved by the Ontario (Canada) Superior Court of Justice on July 7, 2017. Per the Arrangement, Solitario issued 19,788,177 shares of its common stock on July 12, 2017 in exchange for all of the issued and outstanding Zazu Shares, which represented 0.3572 shares of Solitario common stock for each outstanding Zazu Share. Solitario granted stock options to acquire an aggregate of 1,782,428 shares of Solitario common stock to Zazu option holders the (“Replacement Options”) in connection with the Acquisition. The issuance of the shares of Solitario common stock as consideration for the Acquisition was approved at the 2017 annual meeting of Solitario shareholders held on June 29, 2017 (the “Annual Meeting”), with 98.27% of the Solitario shareholders who voted voting “for” the issuance of the shares pursuant to the Arrangement Agreement. The total purchase price of $16,227,000 recorded during the three and nine month periods ending September 30, 2017 is detailed below. Results of operations for Zazu are included in Solitario’s condensed consolidated financial statements from the date of the Acquisition.

The Acquisition was treated as an asset purchase in accordance with Accounting Standards Update No. 2017-01, “Business Combinations,” (“ASU 2017-01”). Solitario adopted the provisions of ASU 2017-01 during the quarter ended September 30, 2017, which provides guidance on the classification of the treatment of business acquisitions as either the purchase of an asset or the purchase of a business. See “Recent Accounting Pronouncements, below. Accordingly, as the purchase of an asset (essentially the interest in the Lik project in Alaska) Solitario capitalized related transaction costs associated with the Acquisition, including the following costs:

The transaction costs and accounts payable assumed, and subsequently paid, less the cash acquired are shown as the cash transaction costs for the nine months ended September 30, 2017 on the condensed consolidated statement of cash flows.

Name Change to Solitario Zinc Corp.

Solitario shareholders voted at the Annual Meeting in favor of an amendment to Solitario’s Articles of Incorporation to change Solitario’s name to “Solitario Zinc Corp.” from “Solitario Exploration & Royalty Corp.” The name change was subject to the completion of the Acquisition and became effective on July 17, 2017. Subsequent to the Acquisition, Solitario’s core mineral property assets are its 39% ownership in the Florida Canyon zinc project (formerly called the Bongará zinc project) in Peru and its 50% ownership interest in the Lik zinc deposit (acquired in the Acquisition).

Convertible Debenture Financing

On April 26, 2017, concurrent with the signing of the Arrangement Agreement, Solitario provided Zazu interim debt financing through a secured convertible debenture issued by Zazu in the principal amount of US$1.5 million (the "Debenture"). The Debenture was secured by way of a general security and pledge agreement on Zazu’s assets and bore interest at a rate of 5% per annum. The Debenture was convertible, at the option of Solitario into Zazu Shares at a price of US$0.22 per Zazu Share. Upon completion of the Acquisition, the Debenture was cancelled.

Business and company formation

Solitario is an exploration stage company as defined in Industry Guide 7, as 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 focus onpartner that has expertise in mining operations, or create a royalty with a third party that continues to advance the acquisition of precious and base metal properties with exploration potential and the development or purchase of royalty interests. As a result of the Acquisition,property. Solitario is moreprimarily focused on the acquisition and exploration of zinc-related exploration mineral properties. However,properties; however Solitario intends to continue towill evaluate for acquisitionand acquire other mineral propertiesbase and hold a portfolio ofprecious metal mineral exploration properties and assets for future sale, joint venture or to create a royalty prior to the establishment of proven and probable reserves. Although Solitario’s mineral properties may be developed in the future by Solitario, through a joint venture or by a third party, Solitario has never developed a mineral property.properties. In addition to focusing on its current assetsmineral exploration properties and the evaluation of mineral properties for acquisition, or purchase of royalty interests, Solitario also expects to continue to evaluateevaluates potential strategic corporate transactions for the acquisition of new precious and base metal properties and assets with exploration potential or business combinations it believesthat Solitario determines to be favorable to Solitario.

Solitario has recorded revenue in the past from the sale of mineral property, including (i) the sale of certain mineral royalty properties includingto 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 theits former Mt. Hamilton project, joint venture property payments andproject; (ii) the sale of a royalty on its former Mt. Hamilton property. Proceedsproject and (iii) joint venture property payments. Revenues and / or proceeds from the sale or joint venture of Solitario’s properties andor assets, although significant when they occur, have not historically been a consistent annual source of cash or revenue and would only occur in the future, if at all, on an infrequent basis in the future.

basis.

Solitario currently considers its carried interest in the Florida Canyon project in Peru and its interest in the Lik project (acquired in the Acquisition)Alaska to be its core mineral property assets. Nexa Resources, Ltd. (“Nexa”), Solitario’s joint venture partner, is expected to continue the developmentexploration and furtherance of the Florida Canyon project and Solitario will monitoris monitoring progress at Florida Canyon. Solitario is currently evaluatingworking 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 September 30, 2017,March 31, 2020, 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 developmentexploration of the Florida Canyon and Lik projectprojects and to potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices has contributedcontribute 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.

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, 2016.2019. 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 our business and financial conditions.
Solitario’s business could be adversely impacted by the effects of the coronavirus (COVID-19) or other epidemics or pandemics. The extent to which the coronavirus impacts Solitario’s business, including our exploration and other activities and the market for 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 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 condensed consolidated financial statements include the accounts of Solitario and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles and are expressed in U.SU.S. dollars.

Revenue recognition

Solitario records delay rental paymentshas 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 revenue in the period received. Any paymentscash 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. Proceeds which exceedIn 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 capitalized costthree 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, without reserves are recognized as revenue. Payments receivedroyalty 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 saleforeseeable 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 properties with reserves are recognizedits sales recorded as revenue to the extent the proceeds exceed the proportionate basis in the assets sold.

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) Solitario’s carrying value of short-term investments; (ii) the recoverability of mineral properties related to its mineral exploration properties and their future exploration potential; (iii)(ii) the fair value of stock option grants to employees; (iv)(iii) the ability of Solitario to realize its deferred tax assets; and (v)(iv) Solitario's investment in marketable equity securities.

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 September 30, 2017, a portionMarch 31, 2020, $425,000 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. At September 30, 2017, Solitario holds short-term investments in United States Treasury securities (“USTS”) of $10,723,000.

Short-term investments

As of September 30, 2017,March 31, 2020, Solitario has $10,723,000$6,325,000 of its current assets in USTSUnited States Treasury Securities (“USTS”) with maturities of 3015 days to 1915 months. The USTS are recorded at their fair value, based upon quoted market prices. As of September 30, 2017,In addition, Solitario has $1,248,000 in separatetwo bank certificates of depositdeposits (“CDs”CD’s”) each with a maximum value of $250,000, and each of which are covered by FDIC insurance to the full face value of the CDs. At September 30, 2017, the CDs have maturities of between 30 days$250,000. The USTS and 18 months. Solitario’s short-term investmentsCD’s are recorded at their fair value, based upon quoted market prices. The short-term investmentsUSTS 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 Solitario’sits mineral properties are capitalized. Solitario capitalizes all of its development expenditures on its projects, subsequent to the completion of a feasibility study. 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, "Accounting for Derivative Instruments and Hedging Activities" (“ASC 815”). Solitario acquired its investment in Vendetta units, including the Vendetta Warrants during 2016. During the three and nine months ended September 30, 2017 Solitario exercised all of its Vendetta Warrants (as defined below in Note 4) and no longer owns any Vendetta Warrants. See Note 4 below. Solitario classified the Vendetta Warrants as derivative instruments under ASC 815 and prior to their exercise recorded the Vendetta Warrants at their fair value as other assets on the consolidated balance sheet. Changes in fair value of the Vendetta Warrants are recognized in the statement of operations in the period of change as gain or loss on derivative instruments.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 and its Vendetta Warrants are recognized in the statement of operations in the period of the change as gain or loss on derivative instruments.

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

Financial Accounting Standards Board (“FASB”)

ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”) establishesestablished a framework for measuring fair value of financial instruments and requires enhancedrequired 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 a liability in an orderly transaction between market participants. 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 CDs,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. The fair value of Solitario’s investment in the Vendetta Warrants was determined by a Black-Scholes model.

See Note 6, “Fair Value,” below.

Marketable equity securities

Solitario's investments in marketable equity securities are classified as available-for-sale and are carried at fair value, which is based upon quoted prices of the securities owned. Solitario records investments in marketable equity securities as available-for-sale 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 in accumulated other comprehensive income within shareholders' equity, unless a decline in fair value is considered other than temporary, in which case the decline is recognized as aunrealized gain or loss in the condensed consolidated statementsstatement 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 20172019 and 2016 have beenthe first quarter of 2020 were conducted primarily in Peru, a portion of the payments under the 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. These provisions of ASC 740 had no effect on Solitario's financial position or results of operations.


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 three and nine months ended September 30, 2017March 31, 2020 and 2016.2019. Potentially dilutive shares totaling 1,928,428 related to outstanding common stock options of 4,373,000 and 4,373,000, respectively, for Solitario common shares for the three and nine months ended September 30, 2017March 31, 2020 and 2019 were excluded from the calculation of diluted earnings (loss)loss per share because the effects were anti-dilutive. There were no similar potentially dilutive securities outstanding during the three and nine months ended September 30, 2016.

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.”

Recent

Recently adopted accounting pronouncements

On January 5, 2017, the

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurements of Credit Losses on Financial Statements (“ASU 2017-01.No. 2016-13”). Among other things, these amendments require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2017-01 clarified the definition of the acquisition of a business or an asset under Accounting Codification Standard 805 (“ASC 804”). ASU 2017-10 utilizes a series of tests or screens to determine if a business combination is the acquisition of a single identifiable asset or of a business. Under the definition of ASU 2017-01, the Acquisition would fall under the classification of the acquisition of an asset. ASU 2017-01No. 2016-13 is effective for Solitario for fiscal year, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted.2019. Solitario adopted the provisions of ASU 2015-01 during the three months ended September 30, 2017, and has accounted for the Acquisition in accordance with the provisions of ASU 2017-01. The adoption of ASU 2017-01 had no other effect on Solitario’s consolidated financial position.

In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09,Revenue from Contracts with Customers (Topic 606, (“ASU No. 2014-09”),2016-13 effective January 1, 2020 which amended the existing accounting standards for revenue recognition. ASU No. 2014-09 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. In July 2015, the FASB deferred the effective date for annual reporting periods beginning after December 15, 2017. The amendments may be applied retrospectively to each prior period (full retrospective) or retrospectively with the cumulative effect recognized as of the date of initial application (modified retrospective). Solitario will adopt ASU 2014-09 in the first quarter of 2018 and apply the full retrospective approach and doesdid not expect the impact on its consolidated financial statements to be material.

In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU No. 2016-02”), which will require lessees to recognize a right-of-use asset and a lease liability for all leases that are not short-term in nature. For a lessor, the accounting applied is also largely unchanged from previous guidance. The new rules will be effective for Solitario in the first quarter of 2019. Solitario does not anticipate early adoption. As ASU No. 2016-02 does not apply to mineral leases, Solitario does not expect the adoption of ASU No. 2016-02 to materially change its current accounting methods and therefore it does not expect the adoption to have a material impact on its consolidated financial position or results of operations.

In January 2016,operations as of or for the three months ended March 31, 2020.

The FASB issued ASU No 2016-01, Financial InstrumentsNo. 2018-13, Disclosure FrameworkRecognition andFair Value (topic 820): Changes to Disclosure Requirements for Fair Value Measurement of Financial Assets and Financial Liabilities (Topic 825) (“ASU No. 2016-01”2018-13”). Among other things, these amendments change the required disclosures regarding (i) transfers between Level 1 and Level 2 fair values; (ii) unrealized gains / losses included in earnings and other comprehensive income for Level 3 instruments; and (iii) amount, reason and policies regarding transfers between Levels. ASU No. 2016-01 revises the classification and measurement of investment in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU No. 2016-01 requires the change in fair value of many equity investments to be recognized in net income. ASU No. 2016-012018-13 is effective for Solitario for fiscal year, and interim and annual periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted.2019. Solitario will adoptadopted ASU No. 2016-01 in the first quarter2016-13 January 1, 2020 which did not have a material impact on its consolidated financial position or results of 2018. Adoption of ASU No. 2016-01 may result in a cumulative effect adjustment to the consolidated statement of equity retained earningsoperations as of or for the three months ended March 31, 2020.
Recently issued accounting pronouncements
The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC. These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) and, following a two-year transition period, the SEC Modernization Rules will replace the historical property disclosure requirements for mining registrants that are included in SEC Industry Guide 7. Under the SEC Modernization Rules, consistent with global standards as embodied by the Committee for Reserves International Reporting Standards (“CRIRSCO”), registrants will be required to disclose specified information concerning mineral resources that have been identified on one or more of its mineral properties. Consistent with CRIRSCO standards the SEC Modernization Rules have added definitions to recognize “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources.” The Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules until its fiscal year beginning January 1, 2021.
Upon adoption of the year of adoption. SolitarioSEC Modernization Rules, among other requirements, the Company will be required to report its mineral resources, if any, as Measured, Indicated or Inferred Mineral Resources in accordance with the SEC Modernization Rules. This will allow investors to evaluate the Company’s resources on a comparable basis with other mining and exploration issuers registered with the SEC. In addition, the SEC Modernization Rules will require the Company to disclose exploration results, mineral reserves, if any, and mineral resources based upon information and supporting documentation prepared by a mining expert (the “qualified person”). The SEC Modernization Rules will require the Company to obtain a dated and signed technical report summary from the qualified person identifying and summarizing the information reviewed and conclusions reached by the qualified person(s) about the mineral resources or reserves for each mineral property. The Company is currently evaluating the new guidancerequirements under the SEC Modernization Rules and has not determined the impact of ASU No. 2016-01what effect adoption will have on its consolidated financial statements.

Royalty sale
On January 22, 2019, Solitario acquiredcompleted the Lik project duringRoyalty Sale to SilverStream for Cdn$600,000. On closing of the Royalty Sale, Solitario received Cdn$250,000 in cash and a convertible note from SilverStream in the principal amount of Cdn$350,000 (the “SilverStream Note”). The SilverStream Note was originally due December 31, 2019, accrued 5% per annum simple interest, payable on a quarterly basis, and is convertible into common shares of SilverStream, at the discretion of SilverStream, by providing Solitario a notice of conversion. In December of 2019, Solitario and SilverStream agreed to extend the due date of the SilverStream Note to June 30, 2020, and to increase the interest rate to 8% per annum simple interest. All other terms of the SilverStream Note remained the same. During the three and nine months ended September 30, 2017 inMarch 31, 2020 and 2019, Solitario recorded interest income from the Acquisition, seeSilverStream Note 1 “Recent developments” above.

Asset Retirement Obligation

In connection with the Acquisition,acquisition of 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, Resources Limited (“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.

Solitario sold 2,000,000 shares of Vendetta Mining Corp. (“Vendetta”) common stock during the three months ended March 31, 2020 for proceeds of $76,000 and recorded a gain on sale of $25,000 on the date of sale. Solitario did not sell any marketable equity securities during the three months ended March 31, 2019 and the change in the fair value of marketable equity securities was related entirely to the unrealized loss on marketable equity securities related to their fair values based upon quoted market prices for the marketable equity securities held by Solitario during that period.
Vendetta Warrants
On July 31, 2019, Solitario purchased 3,450,000 Vendetta units for a total of $233,000. Each Vendetta unit consisted of one share of Vendetta common stock and one Vendetta warrant (the “Vendetta Warrants”). Each Vendetta Warrant entitles the holder to purchase one additional share of Vendetta common stock for a purchase price of Cdn$0.13 per share for a period of three years. On the purchase date Solitario recorded marketable equity securities of $165,000 for the Vendetta shares acquired and $68,000 for the Vendetta Warrants based upon an allocation of the purchase price of the Vendetta units, based upon (i) the fair value of the Vendetta common shares received, based upon the quoted market price for Vendetta common shares and (ii) the fair value of Vendetta Warrants based upon a Black Scholes model. During the three and nine months ended September 30, 2017,March 31, 2020, Solitario sold 2,000,000 and 3,480,000, respectively, Vendetta common shares,charged loss on derivative instruments $7,000 for cash proceeds of $407,000 and $666,000. In addition, during the three and nine months ended September 30, 2017, Solitario exercised Vendetta Warrants, discussed belowchange in Note 4, “Other assets” and received 5,000,000 and 7,240,000, respectively, common shares of Vendetta. Solitario transferred the fair value of the Vendetta Warrants based on a Black Scholes model.
4.        Leases
Solitario adopted ASU 2016-02 effective January 1, 2019 and accounts for its leases in accordance with ASC 842. Solitario leases one facility, its Wheat Ridge, Colorado office (the “WR Lease”), that has a term of more than one year. Solitario has no other material operating lease costs. The WR Lease is classified as an operating lease and has a term of 11 months at March 31, 2020, with no renewal option. At March 31, 2020, the right-of-use office lease asset for the WR Lease is classified as other assets and the related liability as current office lease liabilities in the condensed consolidated balance sheet.

6.        Fair Value

Solitario accounts for its financial instruments under ASC 820. For certain of Solitario’s financial instruments, including cash and cash equivalents short-term investments and payables, the carrying amounts approximate fair value due to their short termshort-term maturities. Solitario’s short-term investments in USTS, CD’s, and marketable equity securities are carried at their estimated fair value primarily based on quoted market prices. The Vendetta Warrants are carried at their estimated fair value at December 31, 2016 of $735,000; based upon a Black-Scholes valuation model, see Note 4, “Other Assets,” above.

Solitario accounts for its financial instruments under ASC 820. ASC 820 establishes a framework for measuring fair value and requires enhanced 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 a liability in an orderly transaction between market participants. ASC 820 also requires 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 significant levels of inputs as follows:

15

·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; or
·Level 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 the three and nine months ended September 30, 2017March 31, 2020 there were no reclassifications in financial assets or liabilities between Level 1, 2 or 3 categories.

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 hierarchy as of September 30, 2017:

7.        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 September 30, 2017both March 31, 2020 and December 31, 2016, Solitario2019, a valuation allowance has been recorded, nowhich fully offsets Solitario’s net deferred tax assets. A valuation allowance, which fully offsets the net deferred tax assets, has been recorded 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.

Itemtem 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, 20162019 and 2015,2018, 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, 2016.2019. 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) Recent Developments

As further described in Note 1 “Business and Significant Accounting Policies,” “Recent developments,” on July 12, 2017 we completed the acquisition of Zazu pursuant to the Arrangement Agreementand acquired all of the Zazu Shares by way of the Arrangement. As a result of the Acquisition Zazu became a wholly-owned subsidiary of Solitario. At closing, we issued 19,788,177 shares of common stock for all of the issued and outstandingZazu Shares. We also grantedtheReplacement Options in connection with the Acquisition. The Acquisition was recorded during the three and nine months ended September 30, 2017 as the acquisition of assets in accordance with ASU 2017-01. The total purchase pricefor the Acquisition was $16,227,000 and has been allocated to the assets acquired, less liabilities.Results of operations for Zazu have been included in our consolidated financial statements from the date of Acquisition.

Effective July 17, 2017 an amendment to our Articles of Incorporation became effective that served to change our name to “Solitario Zinc Corp.” from “Solitario Exploration & Royalty Corp.” Subsequent to the Acquisition, our core mineral property assets are the 39% interest in the Florida Canyon zinc project in Peru and the 50% ownership interest in the Lik zinc deposit (acquired in the Acquisition). We believe the name “Solitario Zinc Corp.” reflects the increased focus of the Company on zinc-related assets.

(b) Business Overview and Summary

We are an exploration stage company under Industry Guide 7, as issued by the SEC, with a focus ofon the acquisition of precious and base metal properties with exploration potential and the development or purchase of royalty interests. Upon the completion of the Acquisition, we have shiftedCurrently our primary focus towardis 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 assets and the evaluation of mineral exploration properties, for acquisition or purchase of royalty interests, we also from time to time evaluate potential strategic corporate 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, 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, we have one exploration property in Peru. We are conducting independent exploration activities in Peru and through joint ventures operated by our partners in Peru and the United States. 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 sale of MH-LLC during 2015, joint venture property paymentsRoyalty Sale in January 2019 and the sale in June 2018 of aour interest in the royalty on our former Mt. Hamiltonthe Yanacocha property. ProceedsRevenues and / or proceeds from the sale or joint venture of our properties or assets, although generally significant when they have occurred in the past, have not historically been a consistent annual source of cash or revenue and would only occur in the future, if at all, on an infrequent basisbasis. We have reduced our exposure to the costs of our exploration activities in the future.

We currently consider our carried interest in our Florida Canyon project in Peru and our recently acquired interest inpast through the Lik project in Alaska to be our core mineral property assets. We expect ouruse of joint ventures. Although we anticipate that the use of joint venture partnerfunding for some of our exploration activities will continue the development and furtherance of the Florida Canyon project and we will monitor progress at Florida Canyon. We are currently evaluating potential exploration and development plans for the Lik project.

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 September 30, 2017,March 31, 2020, we have significant balances of cash and short-term investments that we anticipate using, in part, to (i) fund costs and activities intended to further the developmentexploration of the Lik project, (ii) fund costs and activities intended to further the exploration at the Florida Canyon project, (iii) conduct reconnaissance exploration and (iv) potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices has contributedcontribute 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 Contents

March 31, 2020, the effects of the COVID-19 virus have not had a material effect on Solitario’s activities related to the exploration of its Lik and Florida Canyon projects. However, going forward for the remainder of 2020, we will continue to monitor planned activities for the full year 2020 at both Florida Canyon and Lik. 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.

 (b) Results of Operations

Comparison of the quarter ended September 30, 2017March 31, 2020 to the quarter ended September 30, 2016

March 31, 2019

We had a net incomeloss of $77,000$607,000 or approximately $0.00$0.01 per basic and diluted share for the three months ended September 30, 2017,March 31, 2020 compared to a net loss of $1,119,000$441,000 or approximately $0.03$0.01 per basic and diluted share for the three months ended September 30, 2016.March 31, 2019. As explained in more detail below, the primary reasonreasons for the change toincrease in the net income forloss in the three months ended September 30, 2017 from aMarch 31, 2020 compared to the loss in the first three months of 2019 were (i) the Royalty Sale revenue, net, loss forof $408,000 during the three months ended September 30, 2016 was (i) recording a creditMarch 31, 2019 with no similar mineral property revenue during the 2017 periodthree months ended March 31, 2020 and (ii) a loss on derivative instruments of $25,000 during the three months ended March 31, 2020, with no similar loss in the three months ended March 31, 2019. Partially offsetting the above items were (i) a reduction in exploration expense to $113,000 during the three months ended March 31, 2020 compared to exploration expense of $163,000 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, 2020 compared to general and administrative expense for certain Acquisition related costs, previously expensed, which were capitalized to the purchase price of the Acquisition upon the adoption of ASU 2017- 01; (ii) a decrease in non-cash stock option compensation expense, included in general and administrative expenses to $23,000$425,000 during the three months ended September 30, 2017 compared to $939,000, which included expenses related to the cancellation of options of $721,000 during the three months ended September 30, 2016;March 31, 2019; (iii) an increase in interest income to $38,000$81,000 during the three months ended September 30, 2017March 31, 2020 compared to interest income of $27,000$72,000 during the three months ended September 30, 2016; andMarch 31, 2019; (iv) an increasea reduction in gainthe non-cash loss on sale ofunrealized loss on marketable equity securities to $357,000$233,000 during the three months ended September 30, 2017March 31, 2020 compared to a non-cash unrealized loss on marketable equity securities of $326,000 during the three months ended March 31, 2019 and (v) a gain on sale of marketable equity securities of $10,000$25,000 during the three months ended September 30, 2016. These were partially offset by an (i) increase in exploration expense to $180,000March 31, 2020 with no similar gain during the three months ended September 30, 2017 compared to exploration expenseMarch 31, 2019. Each of $132,000the 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 items during the three months ended September 30, 2016; (ii) a reduction in the gain on derivative instrumentsMarch 31, 2020.
Our net exploration expense decreased to a loss of $18,000$113,000 during the three months ended September 30, 2017March 31, 2020 compared to a gainexploration expense of $163,000 during the three months ended September 30, 2016;March 31, 2019 as a result of (i) a decrease in our reconnaissance exploration activities primarily related to the evaluation of mineral properties and (iii) income tax expense of $74,000/ or entities for potential acquisition or other strategic transactions and (ii) a decrease in our activities at our La Promesa project in Peru and Lik project in Alaska during the three months ended September 30, 2017March 31, 2020 compared to and income tax benefit of $27,000 during the three months ended September 30, 2016. The significant changes for these items are discussed in more detail below.

          Our netMarch 31, 2019, when we were carrying out community work at La Promesa and working with our joint venture partner, Teck, on reviews of exploration expense increased to $180,000 duringdata at Lik. During the three months ended September 30, 2017 compared to exploration expenseMarch 31, 2019 we had three contract geologists in Peru, and our Denver personnel spent a majority of $132,000 during the three months ended September 30, 2016. We increased ourtheir time on reconnaissance exploration activities duringdescribed above and related matters. We have budgeted approximately $976,000 for the three months ended September 30, 2017 primarily related to the completionfull-year exploration expenditure for 2020, which includes approximately $528,000 for Solitario’s share of a preliminary economic assessment on our Florida Canyon project (the Florida Canyon PEA”). The Florida Canyon PEA was completed by SRK Consulting (U.S.), Inc., an independent and internationally recognized mining engineering firm, and reported duringjoint drilling program with Teck at the third quarter of 2017. In addition, we continued to evaluate exploration properties and /or companies for potential acquisitions or other strategic transactions. We anticipate we will continue with our current exploration activities, including evaluation of our newly-acquired Lik project in Alaska, which the bulk of those expenses are planned for the third and as a result wefourth quarter of 2020. We expect our full-year exploration expenditures for 2017 will exceed2020 to be below the exploration expenditures for full-year 2016.

2019, however these expenditures may be impacted by the effects of the COVID-19 pandemic, as discussed above.

Exploration expense (in thousands) by project for the three and nine months ended September 30, 2016March 31, 2020 and 20152019 consisted of the following:

General and administrative costs, excluding stock option compensation costs, discussed below, were $17,000$251,000 during the three months ended September 30, 2016March 31, 2020 compared to $274,000$337,000 during the three months ended September 30, 2016.March 31, 2019. The major components of these costs were related to (i) salaries and benefit expense of $83,000 during the first three months of 2020 compared to salary and benefit costs of $108,000 during the three months ended September 30, 2017 of $162,000 compared to salariesMarch 31, 2019, as we reduced staff and benefits expense of $150,000 in the same period of 2016;taken salary reductions during 2020; (ii) a net credit of $224,000 to legal and accounting related to previously expensed Acquisition expenditures which were capitalized as part of the Acquisition purchase price upon the adoption of ASU 2017-10$11,000 in the first three months ended September 30, 2017, see Note 1 to the condensed consolidated statements “Recent developments,” above,of 2020 compared to $67,000$53,000 in the first three months ended September 30, 2016;of 2019; (iii) office rent and expenses of $24,000$43,000 during the three months ended September 30, 2017March 31, 2020, compared to $23,000$42,000 during the three months ended September 30, 2016;March 31, 2019; and (iv)Directors and officer liability insurance charged to operations of $14,000 during the three months ended September 30, 2017, with no similar item during the same period of 2016 and (v) travel and shareholder relation costs of $39,000$112,000 during the first three months of 2020 compared to $133,000 during the three months ended September 30, 2017 compared to $32,000 during the three months ended September 30, 2016.March 31, 2019. We anticipate the non-stock option compensation and non-Acquisitionfull-year general and administrative costs will be incurred at a comparable ratelower for 2020 compared to the rate in the three months ended September 30, 2017 for the remainder of 2017.

2019.

We recorded $85,000 of stock option expense for the amortization of unvested grant date fair value with a credit to additional paid-in-capital of $23,000 during the three months ended September 30, 2017March 31, 2020 compared to $218,000$88,000 of stock option compensation expense during the three months ended September 30, 2016. During the three months ended September 30, 2016, the holders of options to acquire our common stock voluntarily surrendered for cancellation all options previously granted to such persons and we cancelled the options upon surrender. Upon cancellation, we recorded an additional $721,000 ofMarch 31, 2019. These non-cash stock option compensation expense for the unamortized grant date fair value as of the date of cancellation. See Note 9, “Employee Stock Compensation Plans,” to the condensed consolidated financial statements, above.

During the three months ended September 30, 2017 we sold marketable equity securities for proceeds of $407,000 and recorded a gain on the sales of $357,000, compared to sales of marketable equity security sales for proceeds of $16,000 and a recorded gain on the sales of $10,000 for the three months ended September 30, 2016. During the three months ended September 30, 2017 we sold 2,000,000 Vendetta common shares, and used the bulk of the proceeds of $407,000 to exercise 5,000,000 Vendetta Warrants for $411,000. See Note 3, “Marketable Equity Securities,” above. The sale of marketable equity securities during 2016 consisted of the sale of 3,000 shares of Kinross common stock. We anticipate we will continue to sell some of our holdings of marketable equity securities during the remainder of 2017 related to our overall cash management strategy.

We adjust the fair value of the Vendetta Warrants at each balance sheet date, based upon a Black-Scholes model. During the three months ended September 30, 2017 we recorded a loss on derivative instruments of $31,000charges related to the Vendetta Warrants, compared to a gainexpense for vesting on derivative instruments of $91,000stock options outstanding during the three months ended September 30, 2016. During the three months ended September 30, 2017 we recorded a gain on derivative instruments related to our Kinross calls of $13,000 compared to a gain on derivative instruments during the three months ended September 30, 2017 of $72,000. Upon the exercise of the Vendetta Warrants discussed above, we no longer have any Vendetta Warrants as of September 30, 2017,March 31, 2020 and as a result do not expect to record significant swings in our gain or loss on derivative instruments during the remainder of 2017.

We recorded a deferred tax expense of $74,000 and a deferred tax benefit of $15,000, respectively, during the three and nine months ended September 30, 2017 related to the gains and losses and related valuation allowance related to gains and losses in other comprehensive income during 2017. During the three and nine months ended September 30, 2016, we recorded deferred tax benefits of $27,000 and $264,000, respectively, related to changes in other comprehensive income in the three and nine months ended September 30, 2016. As a result of our exploration activities and other tax deductible expenses, we anticipate we will not have currently payable income taxes during 2017. We provide a valuation allowance for our United States and foreign net operating losses, which are primarily related to our general and administrative expenses and our exploration activities in Peru, respectively. 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.

Comparison of the nine months ended September 30, 2017 to the nine months ended September 30, 2016

We had a net loss of $453,000 or $0.01 per basic and diluted shared for the nine months ended September 30, 2017 compared to a net loss of 1,770,000 or $0.05 per basic and diluted share for the nine months ended September 30, 2016. As explained in more detail below, the primary reasons for the decrease in the net loss during the nine months ended September 30, 2017 compared to the net loss during the nine months ended September 30, 2016 were (i) a decrease in non-cash stock option compensation expense, included in general and administrative expenses to $23,000 during the nine months ended September 30, 2017 compared to $939,000, which included expenses related to the cancellation of options, discussed above, of $721,000 during the nine months ended September 30, 2016; (ii) we recorded interest income of $114,000 during the nine months ended September 30, 2017 compared to interest income of $40,000 as a result of increased interest rate on our outstanding short-term investments during 2017 compared to 2016; (iii) an increase in gain on sale of marketable equity securities to $578,000 during the nine months ended September 30, 207 compared to gain on sale of marketable equity securities of $40,000 during the nine months ended September 30, 2016; and (iv) we recorded a loss on the sale of other assets of $14,000 during the nine months ended September 30, 2016 related to the closure of our Mexico exploration office, with no similar item during 2017. These reductions in net loss were partially offset by (i) an increase in exploration expense to $519,000 during the nine months ended September 30, 2017 compared to exploration expense of $474,000 during the nine months ended September 30, 2016; (ii) depreciation expense increased to $8,000 during the nine months ended September 30, 2017 compared to $4,000 during the same period in 2016 as a result of the addition of $100,000 of exploration equipment at Lik during 2017; (iii) we recorded a reduction in the gain on derivative instruments to $267,000 during the nine months ended September 30, 2017 compared to a gain on derivative instruments of $295,000 during the nine months ended September 30, 2016; and (iv) we recorded a deferred tax benefit of $15,000 during the nine months ended September 30, 2017 related to changes in other comprehensive income compared to deferred tax benefit of $27,000 during the nine months ended September 30, 2016, as discussed above.

Our net exploration expense increased to $519,000 during the nine months ended September 30, 2017 compared to $474,000 in the comparable period of 2016. See the discussion of the comparison of the three months ended September 30, 2017 compared to the three months ended September 30, 2016, above with the major increase in the nine month period of 2017 related to the Florida Canyon PEA and an increase in reconnaissance exploration.

General and administrative costs, excluding stock option compensation costs discussed below, were $877,000 during the nine months ended September 30, 2017 compared to $941,000 in the same period of 2016. The major components of the costs were (i) salaries and benefit expense during the nine months ended September 30, 2017 of $477,000 compared to salaries and benefit expense of $631,000 in the same period of 2016, which included a bonus of $152,000 during 2016 with no similar item during the nine months ended September 30, 2017; (ii) legal and accounting expenditures of $109,000 in the nine months ended September 30, 2017 compared to $90,000 in the same period of 2016; (iii) other costs of $75,000 during the nine months ended September 30, 2017 compared to $66,000 in the same period of 2016; and (iv) travel and shareholder relation costs of $175,000 during the nine months ended September 30, 2017 compared to $154,000 in the same period of 2015.

During the nine months ended September 30, 2016, we recorded $970,000 of non-cash stock option expense with a credit to additional paid-in capital for the amortization of unvested grant date fair value, including $721,000 of non-cash stock option expense of unamortized grant date fair value upon the cancellation of options, compared to $23,000 of non-cash stock option expense during the nine months ended September 30, 2017.2019. See Note 9, “Employee Stock Compensation Plans,” above, for a further discussion ofadditional information on our stock option activity duringexpense.

During the ninethree months ended September 30, 2016.

During the nine months ended September 30, 2017March 31, 2020, we sold marketable equity securities2,000,000 shares of our holdings of Vendetta common stock for proceeds of $666,000$76,000 and recorded a gain on the sales of $578,000, compared to sales of marketable equity security sales for proceeds of $56,000 and a recorded gain on the sales of $40,000 for the nine months ended September 30, 2016. During the nine months ended September 30, 2017 we sold 3,480,000 Vendetta common shares, and used the bulk of the proceeds of $666,000 to exercise 7,240,000 Vendetta Warrants for $578,000. See Note 3, “Marketable Equity Securities,” above. The sale of marketable equity securities during 2016 consisted of the sale of 3,000 shares of Kinross common stock and the sale of 100,000 shares of International Lithium Corp stock. During the nine months ended September 30, 2016, the proceeds from these sales were $56,000 and we recorded a gain on sale of $40,000 onmarketable equity securities of $25,000. After the completion of the sale of these securities.

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 recorded 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 $326,000 during the three months ended March 31, 2019. The loss during the three months ended March 31, 2020 and 2019 was primarily related to a decrease in the value of our holdings of 12,450,000 shares of Vendetta common stock which decreased from a fair value of $479,000 at December 31, 2019 to a fair value of $350,000 at March 31, 2020 based on quoted market prices. In addition we hold 100,000 shares of Kinross, which decreased from a fair value of $474,000 at December 31, 2019 to a fair value of $398,000 at March 31, 2020, the combination of which accounted for the bulk of the unrealized loss on marketable equity securities during the quarter ended March 31, 2020.
We regularly perform evaluations of our mineral property assets to assess the recoverability of our investments in these assets. All long-lived assets are reviewed for impairment whenever events or circumstances change which indicate the carrying amount of an asset may not be recoverable utilizing guidelines based upon future net cash flows from the asset as well as our estimates of the geological potential of an early stage mineral property and its related value for future sale, joint venture or development by us or others. During the ninethree months ended September 30, 2016March 31, 2020 and 2019, we recorded no property impairments.
At March 31, 2020 and 2019, our net operating loss carry-forwards exceed our built-in gains on marketable equity securities resulting in a loss on other assets of $14,000 and property abandonmentnet tax asset position for which we provide a valuation allowance for all net deferred tax assets. We recorded no income tax expense of $10,000 related toor benefit during the closurethree months ended March 31, 2020 or 2019. As a result of our exploration officeactivities, we anticipate we will not have currently payable income taxes during 2020. 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 Mexico.Peru. We recorded no mineral property write-downs duringanticipate 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 nine months ended September 30, 2017.

As of September 30, 2017,March 31, 2020, we have invested $10,723,000$6,325,000 of our current assets in USTS with maturities of 15 days to 1915 months. The USTS are recorded at their fair value, based upon quoted market prices. As of September 30, 2017,In addition, we have invested $1,248,000 in separate CDstwo CD’s each with maximum values of $250,000, each of which is covered by FDIC insurance to the fulla face value of the CDs. At September 30, 2017, the CDs have maturities of between 30 days$250,000. The USTS and 18 months. The CDsCD’s are recorded at their fair value, based upon quoted market prices. We anticipate we will roll over that portion of our USTS and CDsshort-term investments not used for exploration expenditures, operating costs or mineral property acquisitions as they become due during the remainder of 2017.

2020.

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 stock buy-backshare repurchase program, announced on October 28, 2015, and discussed above in Note 9,10, “Shareholders’ Equity, and Accumulated Other Comprehensive Income” to the unaudited condensed consolidated financial statements. The stock buy-backshare repurchase program may be terminated at any time and does not require Solitario to purchase a minimum number of shares.

Loan to Zazu

On April 26, 2017, concurrent with the signing of the Arrangement Agreement, we provided Zazu interim debt financing in the principal amount of US$1,500,000 through the issuance of the "Debenture. The Debenture was secured by way of a general security and pledge agreement on Zazu assets and bore interest at a rate of 5% per annum. The Debenture was convertible, at our option into Zazu Shares at a price of US$0.22 per Zazu Share. Upon completion of the Acquisition, the Debenture was cancelled. See Note 1, to the unaudited consolidated financial statements, “Recent developments,” above.

During the nine months ended September 30, 2017, we sold 3,480,000 common shares of Vendetta for proceeds of $666,000, and recorded a gain on the sale of marketable equity securities of $577,000. During the nine months ended September 30, 2017 we exercised 7,240,000 of our Vendetta Warrants and received 7,240,000 Vendetta common shares, by paying $574,000 cash to Vendetta. The cost of the shares received from the exercise of the Vendetta Warrants was recorded based upon the total of the (i) exercise price of the Vendetta Warrants exercised, $578,000, and (ii) the fair value of the Vendetta Warrants on the date of exercise, which equaled their intrinsic value, $950,000, for a total value of $1,528,000. As of September 30, 2017, we own 11,000,000 common shares of Vendetta, which are carried at their fair value of $2,382,000 based upon quoted market prices, with any unrealized gain or loss included in other comprehensive income.March 31, 2020. In addition, we own other marketable equity securities with a fair value of $13,000$8,000 at March 31, 2020. During the three months ended March 31, 2020 we sold 2,000,000 shares of Vendetta common stock, as discussed above. We anticipate we may sell some of September 30, 2017.

our marketable equity securities during the remainder of 2020 depending on cash needs and market conditions.

Working Capital

We had working capital of $15,094,000$7,978,000 at September 30, 2017March 31, 2020 compared to working capital of $16,671,000$8,487,000 as of December 31, 2016.2019.

As of September 30, 2017,March 31, 2020, our cash balances along with our short-term investments and marketable equity securities are adequate to fund our expected expenditures over the next year.

23

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, securities, or the sale of other exploration projects or assets.

Stock-Based Compensation Plans

In connection with the Acquisition, on July 12, 2017, we granted 1,782,428 Replacement Options.

As of both March 31, 2020, and December 31, 2019 there were options outstanding that are exercisable to acquire 4,373,000 shares of Solitario common stock. The Replacement Options were priced between $2.24 per share and $0.70 per share with terms between 10 months and 18 months. In accordance with the terms of the Acquisition, the Replacement Options were fully vested upon grant. The Replacement Options had a grant date fair value of $164,000, based upon Black-Scholes models with an expected volatility of 67% and a risk-free interest rate of 1.00%. The grant date fair value was capitalized as part of the purchase price of the Zazu assets acquired in the Acquisition.

On September 1, 2017, we granted 200,000 stock options under the 2013 Plan. Theoutstanding options have a five-year life, vested 25% on the date of grant and vest 25% on each of the next three anniversary dates of the date of grant, and have an exercise price ofprices between $0.77 per share and a grant date fair value of $84,000, based upon a Black-Scholes model with a an expected volatility of 64%, and a risk free interest rate of 1.70%. During the three and nine months ended September 30, 2017, we recorded stock option compensation related to these options of $23,000.

On September 1, 2017, we granted, subject to shareholder approval at the next meeting of our shareholders, an additional 2,300,000 stock options under the 2013 Plan to officers and members of the Board of Directors. These options have a five-year life, and exercise price of $0.77$0.28 per share, and a grant date fair value of $970,0000, based upon a Black-Scholes model with a volatility of 64%, and a risk free interest rate of 1.70%. Although the options will vest on the schedule of 25% on date of grant and 25% on each of the next three anniversary dates of the date of grant, the options will not become exercisable in whole or in part unless our shareholders approve the grants, and the option grants will be void if our shareholders do not approve the grants. We will not record any stock option expense related to these options until the shareholder approval is received.

During the nine months ended September 30, 2016 the holders of options to acquire our common stock voluntarily surrendered for cancellation all options previously granted to such persons pursuant to the 2013 Plan and the 2006 Plan. Solitario cancelled the options upon surrender. As a result, there are no outstanding options under the 2006 Plan. See Note 8, “Employee Stock Compensation Plans,” above for a discussion of the activity in our 2013 Plan and our 2006 Plan during 2017.share.

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. On November 7, 2017,During 2019, our Board of Directors extended the term of the share repurchase program until December 31, 2018.2020.

 (d) Cash Flows

Net cash used in operations during the ninethree months ended September 30, 2017 decreasedMarch 31, 2020 increased to $1,308,000$238,000 compared to $1,436,000$172,000 of net cash used in operations for the ninethree months ended September 30, 2016March 31, 2019 primarily as a result of the mineral property revenue, net, cash received during the three months ended March 31, 2019 of $185,000 from the Royalty Sale, discussed above, with no similar item during the three months ended March 31, 2020. This was partially offset by (i) a decrease in non-stock option general and administrative expense 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 generalexploration activities at our La Promesa and administrative expenses notLik projects and a reduction in reconnaissance exploration during 2020 compared to 2019, discussed above. Based upon projected expenditures in our 2020 budget, we anticipate continued use of funds from operations through the remainder of 2020, primarily for exploration related to the Acquisition. Legalour Lik project and accounting costs directly associated with the Acquisition were capitalized in accordance with ASU 2017 – 01, as discussed above in Note 1 “Recent developments.” In addition, as we focused on the Acquisition, we spent less time and expense on other general and administrative matters, including shareholder and investor relations. These reductions were partially offset by a slight increase in exploration expense. We anticipate our cash used from operations will generally continue to be in line with the uses through the nine months ended September 30, 2017.reconnaissance exploration. See “Results of Operations” discussed above for further explanation of some of these variances.

We received $1,478,000

During the three months ended March 31, 2020, we provided $107,000 in cash from investing activities during the nine months ended September 30, 2017 primarily from the sale of $3,254,000 of short-term investments of USTS and CDs. The sale of these short-term investments was anticipated pursuantcompared to our corporate budgets and plans for 2017, after consideration of the expenditures for the Acquisition, and we anticipate we will continue to use short-term investments to fund our operations for the remainder of 2017. As part of the Acquisition, we used $1,500,000$602,000 of cash to extend the loan evidenced by the Debenture, discussed above, and we used net cash for the Acquisition of $417,000, consisting of $899,000 of transaction costs, $491,000 of acquired accounts payable less $974,000 of cash acquired. See Note 1, under “Recent developments,” above. We used $15,518,000 in cashprovided from investing activities during the ninethree months ended September 30, 2016 forMarch 31, 2019. The primary sources of the cash provided related to the net purchaseproceeds from short-term investment sales and purchases of $7,018,000 of CDs$40,000 and $8,500,000 of USTS, discussed above under “Short-term Investments” in “Liquidity$602,000, respectively, during the three months ended March 31, 2020 and Capital Resources.”2019. In addition, during 2016,the three months ended March 31, 2020 we used $289,000 for the purchase of unitssold 2,000,000 shares of Vendetta common stock for proceeds of $76,000, with no similar item last year. We may sell additional marketable equity securities during the remainder of 2020, as discussed above under “Liquidity and Capital Resources,” andabove. However, we used $40,000 for the purchase of royalties on certain non-producing mineral leases in the state of Montana, previously owned by Atna Resources Ltd. We received $666,000 fromdo not anticipate the sale of marketable equity securities during the nine months ended September 30, 2017, from the salewill be a significant source of Vendetta common shares, discussed above, compared to $40,000 from the sale of marketable equity securitiescash during the nine months ended September 30, 2016. We anticipate the use of additional cash for potential exploration and evaluation activities related to our recently acquired interest in the Lik project as well as other on-going exploration activities for the remainder of 2017.2020. We may incur additional costs relatedwill continue to the Acquisition or another potential acquisition or purchase of any additional exploration projects which we anticipate would be funded by the use of funds from the saleliquidate a portion of our short-term investments.

Any potential mineral property acquisition or strategic corporate investment during the remainder of 2020, 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.

We used $28,000$3,000 and $9,000, respectively, for the purchase of our common stock during the ninethree months ended September 30, 2017 compared to the use of $214,000 during the nine months ended September 30, 2016,March 31, 2020 and 2019, as discussed above 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 2017.

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 werecan be no purchasesassurance 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.
