Solitario Receives Final US Forest Service Approval of its Revised Plan of Operations for Drilling on its Golden Crest Gold Project

DENVER, June 24, 2024 - Solitario Resources Corp. ("Solitario") (NYSE American:XPL)(TSX:SLR) is pleased to announce that its final revised Plan of Operations for its Golden Crest project has been signed by US Forest Service. Additionally, the South Dakota Board of Minerals has accepted Solitario's reclamation bond paving the way for exploration drilling to begin. We are now in the process of mobilizing drilling equipment and organizing support equipment necessary for our drilling operations. Several drill targets are planned to be tested, including Downpour, Whirlwind, Matchstick and Mirage. None of these high-quality gold targets have ever been drilled before.

Chris Herald, President and CEO of Solitario, stated: "Final US Forest Service signoff on our Plan of Operations represents a milestone event for Solitario. We are excited to initiate drilling at Golden Crest where we have discovered and developed multiple outstanding drill targets during the past couple of years. Phase-One of the 2024 drilling program consists of 5,000 meters of drilling, and we are prepared to quickly expand the scope of Phase-One 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 and incorporated modifications to the original plan as required under US Forest Service regulations and the NEPA public input process. In addition, the South Dakota Department of Agriculture & 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 ground water quality. We are confident that we will be able to execute our program in a safe and responsible manner."

Walter Hunt to Retire / Golden Crest Management Team Strengthened

Walter Hunt, Solitario's COO, will be retiring from Solitario at the end of June. Walt has been with the Company for over 30 years directing various exploration, development and permitting activities for Solitario.

Chris Herald, President and CEO, stated: "Solitario has been very fortunate to have had such a dedicated and talented executive on its team for his many years of service. Among Walt's many accomplishments for Solitario were directing the discovery team of the high-grade Florida Canyon zinc deposit in Peru, expansion of resources and completion of a feasibility study and mine permitting at our former 80%-owned Mt. Hamilton gold deposit in Nevada. More recently, Walt directed the exploration team at Golden Crest, including managing the drill hole permitting process. Although Walt could have retired several years ago, he made the commitment to complete the initial drill hole permitting process at Golden Crest. With final Forest Service signoff on Golden Crest's Plan of Operation, Walt has decided it's the right time to retire and let our experienced Golden Crest exploration team move the project forward from here.

On a personal note, I have known Walt since my Colorado School of Mines graduate school days in the late 1970's. We are not only long-term Solitario employees that have worked closely together for decades, but are also close personal friends. I wish Walt nothing but the best in his new adventures in retirement and thank him for his incredible contributions to Solitario over the years. Although Walt will be missed on a day-to-day basis, he remains committed to assist Solitario as a valued advisor whenever needed."

Walt Hunt commented further: "This was a difficult decision. Golden Crest is the most exciting gold project I've ever worked on with exceptional potential. However, there comes a time in everyone's career when it's time to step down and go in another direction in one's life. I have total confidence in our Golden Crest team in taking this project to the next level. Our advanced stage zinc projects are also in great hands with our managing partners, Teck and Nexa Resources."

Solitario recently expanded its Golden Crest project management team with the addition of Sandor ("Shawn") Ringhoffer. Sandor comes to Solitario with over 36 years in the gold exploration arena, 19 years of which were spent with Agnico Eagle. Most recently, Sandor was project manager for Agnico Eagle's Gilt Edge gold mine re-evaluation project in the Black Hills. Work on this project included establishing a community relations team, diamond core drilling, geophysics, and complying with a three-way administrative settlement agreement with State and Federal agencies which authorized work on the project. Sandor worked six years in the Black Hills from 1988 through 1994 in the position of Mine Geologist at Golden Reward and at Gilt Edge.

Chris Herald commented: "Sean is a valuable addition to our Golden Crest team with his extensive experience in exploration and permitting in the Black Hills. I am confident that our current management and geologic team at Golden Crest, together with our highly dedicated South Dakota staff, will be successful in advancing Golden Crest."
