Guardian Metal Resources PLC (GMTL) reported new tungsten drilling results from the Tremor and Good Hope Zones at its 100%-owned Pilot Mountain project in Nevada. At the Tremor Zone (north), mineralization has been confirmed over about 200m of strike and 190m of dip, with key intercepts including 64.15m @ 0.20% WO3 (including 14.27m @ 0.34% WO3) in hole PM26-088 and 15.20m @ 0.28% WO3 in PMR26-078. At the near-surface Good Hope Zone, results included 12.95m @ 0.79% WO3 from 12.19m in GH26-01 and 13.11m @ 0.42% WO3 from 2.13m in GH26-02, together representing an apparent 23m thickness at an average 0.58% WO3.

No mineral resource estimate has yet been prepared for Tremor or Good Hope; further drilling and evaluation are required.
Guardian Metal Resources PLC (GMTL) has signed a collaboration agreement with Oritain Global Limited to develop a forensic origin database for tungsten. The database will cover tungsten from Guardian Metal’s co‑flagship Tempiute and Pilot Mountain projects in Nevada and is intended to support provenance verification for governments, industry and end consumers. The initiative is framed around new U.S. defense procurement rules, including Section 854 of the FY2024 NDAA effective January 1, 2027 and Executive Order 14415, which are expected to increase traceability and verified U.S.-origin requirements across the tungsten supply chain. Guardian Metal positions this as a step toward a fully verifiable, domestically sourced U.S. tungsten supply chain and as a strategic differentiator for its Nevada projects.
