Guardian Metal Resources PLC supplements its May 8, 2026 prospectus to register the resale by selling shareholders of up to 72,111,177 ordinary shares, including in the form of American Depositary Shares. Each ADS represents five ordinary shares. The resale is by the selling shareholders or their transferees and is registered on a prospectus supplement filed May 21, 2026.
The supplement also attaches a Form 6-K disclosing the appointment of Dr. Mark Thorpe as an Independent Non-Executive Director, replacing Mark Burnett, subject to completion of the required AIM due diligence process.
Guardian Metal Resources PLC has appointed Dr. Mark Thorpe to its Board as an Independent Non-Executive Director, subject to completion of the required AIM due diligence process. He replaces Mark Burnett, who steps down as Non-Executive Director to focus on other business interests after helping build the company over the past five years.
Dr. Thorpe brings more than 30 years of global mining experience, specialising in sustainability, environmental permitting, community engagement and mine-life-cycle management. The company describes his appointment as an important step as it advances its Nevada tungsten projects and pursues its strategy to help re-establish U.S.-mined tungsten supply.
Guardian Metal Resources PLC reports a major update on historical mine tailings at its Tempiute Tungsten Project in Nevada. Mapping and sampling show tungsten-enriched tailings covering about 550 acres (2.23 km²), and the company has staked 193 mining claims, increasing the Tempiute footprint by over 375%.
Subject to permits, an auger drilling program is targeted to start in June 2026 and run for around three months to characterize tailings and surrounding soils for both environmental evaluation and tungsten resource potential. An independent metallurgical study will assess how best to recover tungsten and other metals and inform the final reclamation design.
Tempiute, a past-producing tungsten mine, is positioned as a co-flagship asset alongside Pilot Mountain as Guardian Metal pursues its strategy to help re-establish a secure, domestically mined U.S. tungsten supply chain for defense and industrial uses.
