Directorate Change

Guardian Metal Resources plc (LON:GMET/OTCQB:GMTLF), a strategic mineral exploration and development company focused on tungsten in Nevada, U.S., is pleased to announce that Mr. Michael X. Schlumpberger, PE MBA, is to be appointed to the Board as a Non-Executive Director, subject to completion of the required AIM due diligence process.

Michael's extensive operational and executive experience in the critical minerals space is uniquely suited to Guardian Metal as it progresses its co-flagship projects to help reshore U.S. tungsten production. During Michael's 20 years at PotashCorp, the world's largest potash producer prior to its merger to form Nutrien, he held a myriad of senior operational roles, refining his skillset in mine development and maintenance, downstream operations, and ESG compliance. Since then, he has gone on to hold a series of operational and executive positions, including most recently Managing Director and Chief Executive Officer at ASX-listed American Pacific Borates Ltd, where, during his tenure, he grew the company from a market cap of AUS$20M to over AUS$900M. Michael currently acts as non-executive director for Rapid Critical Metals, a critical mineral exploration company focused on Australia and North America, and as the President of mining and management consultancy Schlumpberger Inc.. Michael is an American citizen based in New Mexico, U.S.

Michael is replacing Mr. Mick Billing, who will step down from his role as Non-Executive Director upon Michael's appointment to the Board. Mick is retiring following a four year tenure with Guardian Metal. The Board sincerely thanks Mick for his significant contribution to the Company and wishes him the best for his retirement.

J.T. Starzecki, Executive Chairman of Guardian Metal, commented:

"It brings me great pleasure to welcome Michael to the Board. Michael's record of achievements in his almost 40 years in the industry speaks to his distinguished skillset in mining operations, development and management, and will be particularly well-suited to guide Guardian Metal as it advances Pilot Mountain and Tempiute through to development, to ultimately become the cornerstone of U.S. tungsten supply. I look forward to working closely with him as we transform Guardian Metal into the leading producer of American-made tungsten.

"On behalf of the Board, I would like to sincerely thank Mick for his commitment and service to Guardian Metal, during which the Company established itself as a critical component in U.S. efforts to strengthen defence supply chain resilience. He has been instrumental in the rapid advancement of the Company's offering and focus to date, and we wish him all the best for his retirement."

A further announcement, including regulatory disclosures, will be made in due course.
