DENVER, CO / ACCESSWIRE / February 14, 2022 / Solitario Zinc Corp. ("Solitario") (NYSE American:XPL; TSX:SLR) is pleased to announce that it has discovered significant high-grade gold at surface on its Golden Crest project in South Dakota. High-grade gold was discovered at the Downpour Zone over an area measuring approximately 170 by 70 meters in extent and open in all directions (see Figure 1 and Table 1 below). To date, Solitario has received assay results for eleven surface reconnaissance grab samples in the central part of the Downpour Zone (see map). The average gold content for these eleven samples was 12.6 grams per tonne gold ("gpt"), including 50.2, 47.7, 12.2, 8.1, 7.2 and 5.9 gpt gold.

Chris Herald, President and CEO of Solitario, commented: "These initial surface results at Downpour are stunning. In our team's 40-year history of very successful grass roots exploration, we have never encountered undiscovered gold mineralization with these grades at surface. Equally striking to this evolving story, is the fact that nearly all of the reported Downpour high-grade samples came from rocks exposed in the tracks of a primitive jeep roadbed. This demonstrates the total lack of both modern-day and historical exploration in an area immediately west of the nearby supergiant Homestake-Wharf gold mining district, and strongly suggests that our work to date is literally, just starting to scratch the surface."

¹Reconnaissance rock grab samples are selective in nature, and therefore reported mineralization and assay results may not be representative nor reflect economic viability.
²Previously reported assay.

Initial assay results for rock sampling at the high-grade Downpour zone were not received until late in the 2021 field season. Consequently, work was suspended in early December before we could complete another phase of evaluation. However, we were able to collect 14 additional rock samples and 24-meters of channel sampling, before weather forced the cessation of activities. We anticipate reporting these results within the next few weeks.

14 Target Zones Discovered to Date

In addition to the Downpour zone, Solitario has identified another 13 separate zones of gold-bearing mineralization (see Table 2), many of which contain surface gold grades in excess of 1.0 gpt gold. Nine of these zones are clustered within an area measuring seven by five kilometers in size. Based on these results, and our ongoing exploration program, Solitario has expanded its mineral claim position from approximately 21,300 acres to nearly 28,000 acres of mineral rights, or 44 square miles (113 square kilometers).

Rock and Soil Sampling Program

During the 2021 field season, Solitario collected 972 reconnaissance grab samples of rock and 5,575 soil samples (B-horizon). At Golden Crest there is almost a total lack of outcropping rocks, but generally, there is less than 30 centimeters of soil cover on top of sub-crop and bedrock. Consequently, sampling bedrock is difficult, but soils provide an excellent alternative medium to sample. Solitario's work to date has defined multiple areas of significant anomalous trace elements. Many of these anomalous areas have been found to correlate well with gold-bearing rocks, float or sub-crop.

2022 Work Program

The 2022 exploration program will be one of the most active programs in Solitario's history. Besides the 14 gold prospects that have been defined to date, there remain multiple large areas displaying significant trace element concentrations in soils that have never been prospected, sampled for gold-bearing rocks or evaluated by a geologist. Additional sampling and geologic evaluation of these anomalous areas will be one of Solitario's primary activities for the 2022 work program. With less than 20% of Solitario's land position having been soil sampled or prospected for mineralized rocks, significant additional sampling is also planned for 2022.

Other important work scheduled for 2022 is geophysical surveying of select target areas, permitting drilling sites, and drilling (permitting dependent).

Chris Herald, President and CEO of Solitario, commented further, "The results of our 2021 exploration work at Golden Crest strongly supports our belief that a large gold endowment could exist at depth in limestone covered terrain west of the Super Giant Homestake-Wharf gold district. We are excited about our planned 2022 exploration program and are confident that multiple new high-quality drill targets will be identified. Collecting multi-gram gold samples in the shadow of a +70-million-ounce gold district, in an area with virtually no evidence of any past exploration, is truly remarkable. We firmly believe that the Golden Crest project could emerge into one of the most important greenfield exploration projects in North America."

Sampling Methodology, Chain of Custody, Quality Control and Assurance

The collection of all surface rock samples was supervised by project geologists, including chain of custody. Rock samples were reconnaissance select grab samples that display alteration, usually silicification and hydrothermal brecciation. These samples were derived mainly from residually weathered rock fragments, sub-crop, and less commonly, outcrop. The significance of these samples is limited to determining whether gold, or trace elements usually associated with gold, are present within rocks affected by hydrothermal alteration fluids and assay results may not be representative of, nor verify economically mineable mineralization at depth. Samples were analyzed by Skyline Assayers & Laboratories in Tucson, AZ, a laboratory accredited in accordance with the standards of ISO 17025:2017. The samples were crushed and pulverized, and sample pulps were analyzed using industry standard fire assay methods. A certified reference sample or duplicate was inserted at least every 20th sample.
