Guardian Metal Resources (NYSE:GMTL) has delineated approximately 550 acres of tungsten-enriched historical mine tailings at its Tempiute Tungsten Project and has staked 193 mining claims, increasing the project's footprint by more than 375%.
Tempiute, a past-producing tungsten operation in south-central Nevada, could offer a nearer-term source of domestically produced tungsten and a reclamation outcome if tonnage and grade support reprocessing.
"We believe the historical tailings represent a unique opportunity that could provide near-term support to the U.S. tungsten supply chain alongside a meaningful reclamation outcome," Oliver Friesen, CEO.
Subject to permits, an auger drilling programme is targeted to commence in June 2026 and is expected to take approximately three months to characterise tailings material and surrounding soils for environmental evaluation and resource potential.
Previously milled material at surface and existing on-site infrastructure mean a reprocessing route could compare favourably on cost and timeline with a conventional mining project, subject to confirmation of sufficient tailings tonnage and grade.
An independent metallurgical study has been commissioned to identify the most effective recovery method for tungsten and other metals from the tailings, with results expected in the coming months.
The work forms part of Guardian Metal's push to help rebuild a U.S. supply chain for the defence-critical metal while progressing its environmental inquiry at Tempiute.
