Guardian Metal Resources (LSE:GMET) has lodged its first S-K 1300 Technical Summary Report alongside an updated, pit-constrained Mineral Resource Estimate for the Desert Scheelite deposit at its Pilot Mountain tungsten project in Nevada. The update points to a 16% lift in indicated resources compared with a 2018 scoping study and supports the potential for an open-pit mining operation.
The project is underpinned by a US$6.2 million investment from the U.S. Department of War’s Defense Production Act, providing momentum for a full pre-feasibility study. Guardian Metal has assembled a broad group of specialist engineering and environmental consultants to progress the work and has mobilised a second drill rig to expand exploration across several target zones.
The company is aiming to complete the pre-feasibility study by the end of the first half of 2026, followed by accelerated permitting. Subject to approvals and development timelines, first commercial production is targeted before the end of 2028, potentially marking the first new domestic tungsten mine in the United States in over ten years.
