Solitario Reports 2022 Progress and Future Work Plans at Lik and Florida Canyon Zinc Projects

DENVER, CO / ACCESSWIRE / May 18, 2022 / Solitario Zinc Corp. ("Solitario") (NYSE American:XPL)(TSX:SLR) is pleased to update exploration and other associated activities on its Lik and Florida Canyon high-grade zinc projects and joint venture plans for the remainder of 2022.

Lik Zinc Project (Alaska: Joint Venture: 50% Solitario / 50% Teck Resources)

The Lik project (100% basis) hosts an Indicated Resource of 17.6 million tonnes grading 8.07% zinc, 2.68% lead and 50.1 grams per tonne silver and an additional 2.8 million tonnes of Inferred Resource grading 8.64% zinc, 2.73% lead and 38.9 grams per tonne silver. The project is situated approximately 17 kilometers (10.4 miles) northwest of Teck's operating Red Dog mine, one of the world's largest, highest grade and lowest cost zinc mines.

Solitario and its joint venture partner, Teck American Incorporated, a wholly owned subsidiary of Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) ("Teck") recently approved a jointly funded budget for the 2022 Lik work program that consists of exploration drilling and gravity geophysics.

Three core holes totaling 650 meters (2,145 ft.) are planned at Lik during the summer field season to test for resource extensions on the northeast and northwest margins of the currently defined resource footprint, with the third hole on the southern margin. Of note, one of the planned drill holes will also test the potential for stacked mineralization. The Induced Polarization geophysical survey conducted on the Lik property in 2021 suggested that the mineralized horizon hosting the Lik deposit flattens to the west and could be at drillable depths in a valley floor situated approximately three kilometers to the west. The planned gravity geophysical survey will test for gravity anomalies potentially associated with buried zinc mineralization.

Teck Includes the Lik Deposit in its Zinc Satellite Initiative

On May 12, 2022, Teck announced the formation of its Zinc Satellite initiative to surface value from Teck's portfolio of world-class zinc development assets. The Lik Zinc Project is one, among five projects selected for Teck's value creating initiative. View Teck's press release in its entirety here. Teck is currently the world's largest net zinc miner based on zinc production from Red Dog in Alaska and Antamina in Peru.

Florida Canyon Zinc Project (Peru: Joint Venture: 39% Solitario / 61% Nexa Resources)

The Florida Canyon project (100% basis) hosts an Indicated Resource of 2.4 million tonnes grading 10.62% zinc, 1.33% lead and 15.0 grams per tonne silver and an additional 14.9 million tonnes of Inferred Resource grading 9.63% zinc, 1/26% lead and 11.3 grams per tonne silver. Solitario's joint venture partner, Nexa Resources S.A. (NEXA) ("Nexa"), is focusing its 2022 work program in three critical areas to advance the project:

• The first is to finish an access road to several near-by communities that currently have no vehicle access. This effort is part of the joint venture's social commitment to people and communities in the vicinity of the Florida Canyon project area. Several kilometers of new road have been completed, as well as significant upgrading of previously pioneered road. The road is expected to be completed before the end of the year.
• The second significant 2022 program is completion of a comprehensive metallurgical testing program focusing on sulfide dominant mineralization. Nearly five tonnes of previously drilled mineralized core will be subjected to a variety of tests to better estimate zinc, lead and silver recoveries, as well as the grade and quality of Florida Canyon concentrates that would be deliverable to smelters.
• Finally, drill hole permitting is well underway to significantly expand the area permitted for drilling activities for 2023 and beyond. The permit application will enlarge the area permitted for drilling by approximately 500 percent. Over 80 new drill hole sites are planned in areas to the south, east and southeast of the Florida Canyon deposit. Multiple drill holes can be completed from each site. These drill sites are located on trend with the Florida Canyon deposit to the south and a parallel trend a couple kilometers to the east. Both of these multi-kilometer trends have undrilled high-grade zinc mineralization at surface comparable to the surface mineralization at Florida Canyon.

Chris Herald, President and CEO of Solitario, commented, "With all the excitement surrounding the high-grade gold results on our Golden Crest gold project in South Dakota, many of our new shareholders may not realize the significant underlying value of our two high-quality zinc assets that are joint ventured with two of the leading zinc producers in the world.

The three major work programs at Florida Canyon are all critical to the future advancement and development of the project. In addition, the Lik project is clearly entering an exciting new phase with our 2022 drilling program. The drilling program is focused on potentially expanding the Lik resource in three different areas of the existing deposit, while the planned geophysical gravity survey could demonstrate significant new value potential for the project. We are extremely pleased that our two joint venture partners, Teck and Nexa Resources, remain committed to meaningful advancement to both of these large high-grade zinc projects. We look forward to sharing the results of these activities with our shareholders as work progresses."

Background Information on the Lik and Florida Canyon Projects

Total Lik Mineral Resource: Tonnes and Grade

(Refer to SK-1300 Technical Report Summary for important resource estimation assumptions)

The Lik deposit is a large sediment-hosted zinc-lead-silver deposit in the Red Dog mining district that can potentially be mined by open pit mining methods. The Lik South deposit remains open down-dip, while, the Lik North deposit remains open down-dip and to the north. A total of about 38,000 meters (125,300 ft.) of drilling in 229 holes has been completed on the Lik property to date. The Lik property position consists of State of Alaska mining claims totaling 2,460 hectares (6,075 acres). Additional information is available in the Company's 2022 SK-1300 Technical Report Summary (link).

Total Florida Canyon Mineral Resource: Tonnes and Grade

(Refer to SK-1300 Technical Report Summary for important resource estimation assumptions)

The Florida Canyon deposit is a Mississippi Valley Type, carbonate-hosted high-grade zinc deposit. It is an advanced exploration project with approximately $75 million in partner investments (526 drill holes; 134,416 meters). A 43-101 Preliminary Economic Assessment demonstrates robust economics at $1.20/lb. zinc price and can be accessed here (link). The Florida Canyon resource is located within 16 contiguous mining concessions covering approximately 12,600 ha (31,100 acres).
