RNS Number : 8644F  Guardian Metal Resources PLC  03 November 2025

3 November 2025

Guardian Metal Resources plc

('Guardian Metal' or the 'Company')

Mr. Michael X. Schlumpberger appointment to the Board

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.

About Guardian Metal Resources

Guardian Metal Resources PLC (LON: GMET, OTCQX: GMTLF) is a strategic mineral
exploration and development company driving the revival of U.S. tungsten
production and strengthening America's independence in defense metals. The
Company is advancing two co-flagship tungsten projects, Pilot Mountain, one of
the largest undeveloped tungsten deposits in the U.S. and Tempiute, formerly
America's largest producing tungsten operation, both located in Nevada, one of
the top-rated mining jurisdictions in the U.S.

In July 2025, Golden Metal Resources (USA) LLC, a wholly-owned subsidiary of
Guardian Metal, was awarded US$6.2M from the U.S. Department of War under
Title III of the Defense Production Act of 1950 to support the rapid
advancement and pre-feasibility study for the Pilot Mountain tungsten
Project.  Guardian Metal Resources joined both the Defense Industrial Base
Consortium and the Cornerstone Program. The Company has also announced plans
to pursue a U.S. listing in the first half of 2026.

Tungsten is a strategic mineral essential to the defense, energy transition,
technology, and industrial sectors. Against the backdrop of evolving
geopolitical dynamics and Chinese export restrictions on tungsten, Guardian is
positioned to play the leading role in rebuilding a reliable domestic supply
chain for this critical metal.
