SOLITARIO RECEIVES POSITIVE USFS DECISION MEMO APPROVING ITS PONDEROSA DRILLING PLAN OF OPERATIONS

The U.S. Forest Service -- Northern Hills district, has issued its decision memo for Solitario Resources Corp.'s Ponderosa drilling program in South Dakota. The decision memo documents the completion of the NEPA process for the project. Subject to Solitario incorporating several additional design features into the plan and submitting these modifications to the U.S. Forest Service, Solitario can proceed with its drilling program in mid-May.

The Ponderosa prospect displays the largest high-grade-gold area discovered to date on the Golden Crest property position. Surface rock grab samples containing multigram gold are scattered over an area nearly 2.0 by 1.5 kilometres in size. Forty-nine drill platforms were approved in the Ponderosa permit.

Chris Herald, president and chief executive officer of Solitario, stated: "We are excited to initiate drilling on the Ponderosa area of the Golden Crest project, where we have defined multiple outstanding drill targets during the past couple of years. Phase 1 of the 2026 drilling program consists of 5,000 metres of drilling, and we are prepared to quickly expand the scope of phase 1 drilling should early results warrant. We now look forward to reporting our progress and results.

"Our exploration team designed a comprehensive program that protects the environment, including water and surface resources, and the safety and health of our employees and other parties using the forest. The U.S. Forest Service has thoroughly vetted our proposed surface activities and impacts, solicited stakeholder input, and incorporated modifications to the original plan as required under U.S. Forest Service regulations. In addition, the South Dakota Department of Agriculture and Natural Resources has also provided input and guidance to our proposed drilling activities to ensure compliance with all state regulations, especially as it pertains to ensuring groundwater quality. We are confident that we will be able to execute our program in a safe and responsible manner."
