Solitario Amends Technical Report and Clarifies Technical Disclosure for Its Florida Canyon Zinc Project

DENVER, CO / ACCESSWIRE / May 28, 2021 /Solitario Zinc Corp. ("Solitario" or the "Company") (NYSE American:XPL)(TSX:SLR) announces that, as a result of a review by staff of the Ontario Securities Commission, the Company is issuing the following news release regarding its technical disclosures made with respect to the Florida Canyon Project in Peru.

On April 7, 2021, the Company filed on Sedar "NI 43-101 Technical Report on Resources Florida Canyon Project, Amazonas Department, Peru ("2021 Technical Report")." Subsequent to that filing, the Company referred to technical information contained in its previously issued 2017 "NI 43-101 Technical Report Preliminary Economic Assessment Florida Canyon Zinc Project Amazonas Department, Peru ("2017 PEA")" in a news release dated April 7, 2021., on its website related to the Florida Canyon project and a corporate presentation (PDAC Virtual Conference) made on March 8, 2021. The 2021 Technical Report did not incorporate certain required disclosure information from the 2017 PEA to allow the Company to refer to the 2017 PEA. The Company has amended the 2021 Technical Report to include all such information required from the 2017 PEA to allow the Company to refer to information contained in the 2017 PEA on its website and in corporate presentations. The resource estimates from the 2021 Technical Report did not change as a result of this amendment.

In addition, the Company posted a video on its website on March 6, 2021 and information on slide 7 in a corporate presentation (PDAC Virtual Conference) made March 8, 2021, that contained information from an internal analysis concerning mine life and cash flows that are not supported by a technical report and should not be relied upon. For this reason, the Company is retracting all references to this internal study.

Information contained within this release is approved by Mr. Walt Hunt, COO for Solitario Zinc Corp., who is a qualified person as defined by National Instrument 43-101.
