Solitario Cuts 24.0-Meter Channel Sample Grading 9.69 GPT Gold and Reports Additional High-Grade Grab Samples*1 Up to 126 GPT Gold on its Golden Crest Project

DENVER, CO / ACCESSWIRE / March 1, 2022 / Solitario Zinc Corp. ("Solitario") (NYSE American:XPL)(TSX:SLR) is pleased to report that it has received assay results for 24 meters (78.8 feet) of continuous rock chip-channel sampling for its Downpour Zone - Golden Crest Project, South Dakota. The grade of the entire 24-meter interval averaged 9.69 grams per tonne ("gpt") gold. Importantly, gold mineralization, defined by the channel samples, is open in all directions. Assay results for each of the eight three-meter chip-channel samples are provided in Table 1 and the attached google earth image (See for Downpour Zone Image).

In addition to the channel samples, results for 14 new composite grab samples were received. Highlights of this sampling include 126.0, 83.5, 52.3, 30.1, 23.3, 19.4 and 15.2 gpt gold. Results of all 14 new samples and 11 previously reported Downpour composite grab samples are reported in Table 2 (See Downpour Zone Image).

Chris Herald, President and CEO of Solitario, stated: "We have had an absolutely amazing start to this exciting project. These chip-channel results confirm that our initial high-grade surface results at Downpour represent significant bedrock mineralization. Starting in mid-2021 from virtually ground zero, our geologic team has learned a lot about the nature of mineralization at Golden Crest. The results here are just the beginning of our planned aggressive 2022 exploration program to discover new areas of mineralization, further define known drill targets, and exploration drilling, pending permitting."

*²True width/ thickness of mineralization cannot be determined because of the lack of sufficient outcrop.

Initial assay results at the high-grade Downpour Zone were not received until late in the 2021 field season. Immediately after receiving the first high-grade samples, Solitario's exploration crews laid-out 105 meters of chip-channel sampling in rocks that appeared mineralized. Unfortunately, a significant snowstorm occurred early in this program and only 8 samples were collected before road closures prematurely terminated sample collection. Completing this chip-channel sampling program will be a priority early in the 2022 field season.

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

14 Target Zones Discovered to Date
In addition to the Downpour Zone, Solitario has identified another 13 separate zones of gold-bearing mineralization (see news release dated February 14, 2022; 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. We anticipate reporting another 25 additional composite grab sample results within the next several weeks.

Chris Herald, President and CEO of Solitario, commented further, "As I've stated before, we firmly believe that the Golden Crest project could emerge into one of the most important greenfield exploration projects in North America. 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."

*² Sampling Methodology, Chain of Custody, Quality Control and Assurance
The collection of all surface grab rock samples was supervised by project geologists, including chain of custody. Rock grab samples were reconnaissance select composite samples that usually displayed alteration, typically 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. Chip-channel samples were more systematically collected as a measured continuous sample of bedrock. The chip channel assays are thought to be more representative of bedrock mineralization in comparison to grab samples. 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.
