Amendment Description This Amendment No. 1 on Form 10-K/A (this “Amendment”) to the Annual Report on Form 10-K of Solitario Zinc Corp. (the “Company”) for the fiscal year ended December 31, 2019, initially filed with the Securities and Exchange Commission (the “SEC”) on March 2, 2020 (the “Original Filing”), is being filed to correct an administrative error in the Original Filing. The Original Filing inadvertently failed to print the conformed signature of Plante & Moran, PLLC on the Report of Independent Registered Public Accounting Firm (the “Audit Report”). Solitario had received the manually signed Audit Report from Plante & Moran, PLLC prior to filing the Original Filing. This Amendment is being filed solely to add “/s/ Plante & Moran, PLLC” to the Audit Report. This Amendment includes Item 8, “Financial Statements and Supplementary Data” in its entirety and without change from the Original Filing other than the addition of the conformed signature of Plante & Moran, PLLC on the Audit Report. In addition, pursuant to the rules of the SEC, the exhibit list included in Item 15 of Part IV of the Original Filing has been amended to contain currently-dated certifications from the Company’s Chief Executive Officer and Chief Financial Officer, as required by Section 302 of the Sarbanes-Oxley Act of 2002. The certifications of the Company’s Chief Executive Officer and Chief Financial Officer are filed as exhibits to this Amendment. Except for the foregoing amended information, this Amendment does not amend or update any other information contained in the Original Filing. Therefore, this Amendment should be read together with other documents that the Company has filed with the SEC subsequent to the filing of the Original Filing. Information in such reports and documents updates and supersedes certain information contained in the Original Filing.
