Solitario Zinc Corp. reported that it has received assay results for an additional 19 surface trench samples for its Golden Crest Project, South Dakota (see Downpour Zone Image for a detailed map depicting the relative orientation of all four trenches). Trenching highlights include: Trench 1: 27.0 meters (90.0 ft.) @ 15.0 grams per tonne gold ("gpt") Additional new sampling at the western margin of Trench 1 increased the average grade significantly and added to its length by 3.0 meters from the previously reported (March 1, 2022) 24.0 meters @ 9.69 gpt gold.

Assays are pending for an additional extension of 6 meters of trenching immediately west of Trench 1. Trench 2: 30.0 meters (101.1 ft.) @ 11.1 gpt gold. Trench 2 is oriented roughly north-south and perpendicular to Trench 1. Assay results in this trench consist entirely of newly reported assay intervals.Trench 3: 12.0 meters (40.4 ft.) @ 0.56 gpt gold. Trench 3 is situated 30 meters south of Trench 2. Assays are pending for the thirty meters between Trench 2 and 3. Trench 4: 9.0 meters (30.3 ft.) @ 2.61 gpt gold; Trench 4 is situated about 9 meters east of Trench 1. Soil cover is too deep between Trench.

1 and 4 to obtain a representative sample. Results are pending for 7 samples (21.0 meters) east of Trench 4. Drill hole permitting has advanced significantly since its initiation in the spring of 2022, when a Plan of Operations was filed with the U.S. Forest Service. Environmental baseline studies in support of permitting documents required for drilling are currently in progress.

Core drilling is scheduled to begin in the second quarter of 2023. Solitario's exploration programs in 2021 and 2022 have consisted of surface prospecting and a pilot level induced polarization geophysical survey. Surface prospecting has included sampling of bedrock, float rocks and soils.

Future plans include additional geophysical surveys, geologic mapping and continued surface sampling. Permitting has been initiated for a core drilling program scheduled to be conducted next spring and summer. The 28,000-acre Golden Crest property is located in southwestern South Dakota.

Solitario's property position constitutes a 100%-owned strategic land position along the western extension of the Homestake-Wharf mining district that has produced approximately 52 million ounces of gold with another 30 million ounces in historical resources. Approximately 60% of the land position is subject to mining leases with a private party. The project area is in a safe jurisdiction with highly developed infrastructure, an unbroken 145-year record of continuous gold mining, a skilled mining workforce, and a history of high-grade, underground mineable gold deposits.
