Guardian Metal Resources (OTCQB:GMTLF) provided an operational update for its Tempiute tungsten project (October 23, 2025). The company has completed 15 diamond drillholes totaling >2,185m since early September and reports that every hole intersected scheelite-bearing skarn. On-site core logging, cutting and sampling facilities are established to accelerate assays, while mill-site refurbishments continue.
Exploration work includes a 7.35 line-km IP survey showing resistivity correlations with skarn, a 435 line-km drone magnetic survey under inversion, a 100+ sample gallium study with University of Bristol, and beneficiation/metallurgical studies of stockpiles and tailings. Baseline environmental studies are planned for early 2026.
Guardian Metal Resources (OTCQB:GMTLF) has announced exceptional assay results from its 100%-owned Pilot North tungsten-copper project in Nevada. The company collected 92 rock chip samples from the recently staked 102 BLM Lode Claims, revealing significant mineral concentrations including copper grades up to 14.65%, silver up to 708 g/t, and tungsten trioxide up to 0.59%.
The Project, located 15km northwest of the company's Pilot Mountain project, encompasses five historical World War II-era mines: Copper Head, Western Metals, Muller Mountain, Jasper, and Tungsten Valley. The geology mirrors that of Pilot Mountain, with tungsten-copper bearing skarns at granitic intrusion contacts.
This strategic acquisition aligns with Guardian Metal's mission to establish itself as a cornerstone of U.S. tungsten supply, supporting national efforts to reduce foreign supply chain dependence for this critical defense mineral.

Guardian Metal Resources (OTCQX:GMTLF) has launched its first diamond drilling program at the Tempiute tungsten project in Nevada, marking the first drilling activity at the site since the 1980s. The program targets multiple brownfield exploration sites and new skarn zones along the eastern contact zone.
The Phase I program encompasses 19 drill targets, with Phase II targets to be determined based on initial results. The project's proximity to ALS Laboratory in Reno enables efficient sample processing and regular results updates. Tempiute, historically the USA's largest tungsten mine in the 1980s, represents a strategic asset in Guardian Metal's mission to establish domestic tungsten supply chains for U.S. defense and economic security.
Guardian Metal Resources (OTCQB:GMTLF) has strengthened its U.S. government relations through membership in two strategic defense programs: the Defense Industrial Base Consortium (DIBC) and the Cornerstone Program.
