Appointment of CFO and Board Changes

Guardian Metal Resources plc (LON: GMET, OTCQX:GMTLF, NYSE A:GMTL), a U.S.-focused exploration-stage company focused on tungsten in Nevada, United States, is pleased to announce the appointment of Mr Jake Mather as Chief Financial Officer ("CFO") with effect from today, 26 March 2026. At the same time, Mr Benjamin ("Ben") James Hodges, currently the Company's Finance Director and executive director of the Company, will step down from his executive role and remain on the Board as a Non-Executive Director.

Jake is an accomplished mining financial professional with over 20 years experience in the industry and a proven track record of maximizing shareholder value through complex financial management, M&A activities, and operational optimization. Previously, Jake was the CFO at Golden Queen Mining Company in California where he supported a divestment process. Most recently, he was the Vice President Business Development at Ceibo, a Chilean based copper sulfide leaching company where he led activities in North America. Jake also worked 12 years at Rio Tinto in a variety of finance & strategy roles, directing corporate strategy efforts including internal investment processes and external contracts. Jake is a U.S. national based in Salt Lake City, Utah.

Ben was appointed Financial Director of Guardian Metal in December 2024. Since his appointment, he has been responsible for aspects of the Company's finance function including audit lead, financial reporting and tax planning, as well the oversight of financial and reporting processes. As such, he has played an integral role in the rapid growth of the Company, including the successful raising of over US$21 million during the course of his tenure, and the acquisition of the Tempiute Tungsten Mine & Mill ("Tempiute"). Ben will today step down as Financial Director and assume his role as a Non-Executive Director, and as Chair of the Audit Committee.

J.T. Starzecki, Executive Chair, commented: 

"We are delighted to welcome Jake to the Guardian Metal team at an important stage for the Company. He brings with him a wealth of experience, including as leader of financial divisions within fast-growing, natural resource organisations, suited to Guardian Metal as we progress the development of our U.S.-based tungsten projects.

"We also express our sincere thanks to Ben who has played a central role in defining and delivering the Company's strategy to date, including equity raises and the acquisition of Tempiute. We are pleased that Ben will remain on the Board as a Non-Executive Director, allowing the Company to continue to benefit from his expertise and deep knowledge of the business, as the team delivers on our next phase of growth."

About Guardian Metal Resources

Guardian Metal Resources PLC (LON: GMET, OTCQX: GMTLF, NYSE A: GMTL) is a U.S.-focused exploration-stage company focused on tungsten in Nevada, United States. Its principal tungsten asset is the Pilot Mountain project, followed by the Tempiute project, which are both situated in historic tungsten districts with well-known occurrences of mineralization that have seen prior tungsten mining activity by third parties.

In July 2025, the U.S. Department of War (DoW), under Title III of the Defense Production Act of 1950, as amended, invested US$6.2 million in Golden Metal Resources (USA) LLC, a wholly-owned subsidiary of Guardian Metal Resources PLC, to support the Pilot Mountain PFS. The Company completed an initial public offering of American Depositary Shares in the United States in March 2026.

Tungsten is used across defense, energy transition, technology and industrial applications. The Company's projects are located in the United States and are focused on potential future development.
