Highlights

  • American Tungsten launches next phase of Idaho-based IMA Mine rehabilitation

  • Rehabilitation and infill drilling part of broader plan for tungsten supply security

  • Strategic discussions ongoing with US federal agencies to support development

Canadian critical minerals company American Tungsten (CSE:TUNG) is intensifying development at the historical IMA Mine in Idaho as it works to address North America’s reliance on secure tungsten supply. While not part of the ASX 200 or All Ordinaries, American Tungsten’s North American positioning places it at the intersection of growing strategic focus on domestic sourcing of key industrial and defense metals.

The company has commenced rehabilitation of the zero level drift at the IMA Project, a foundational move in assessing the condition of historical underground infrastructure and establishing access to drill stations that support exploratory activities.

Rehabilitation and Development Plan in Motion

The rehabilitation strategy includes engineering assessment of portals, confirmatory infill drilling, and metallurgical sampling to determine the technical feasibility for future operations. In parallel, the company is finalising the development scope and execution timelines for this advanced-stage project.

American Tungsten has confirmed it secured preliminary approval for its remediation plan. The project aims to restore vital underground infrastructure to support long-term development while addressing environmental compliance.

Resource Definition and Drilling Program Scheduled for Q3

The upcoming exploration phase will feature a diamond drilling program targeting both tungsten resource expansion and assessment of underlying molybdenum porphyry systems. Data from the drill program, along with compiled historical records, will contribute to defining an initial resource estimate for the IMA Mine.

This dual-track approach—revitalising a historically significant mine while mapping new resource potential—aligns with the broader movement to re-establish domestic mineral production hubs in the region.

Strategic Momentum and Federal Engagement

The company remains focused on strengthening its position in the critical minerals ecosystem through collaboration with engineering and environmental teams. Ongoing dialogue with the US Department of Defense and Department of Energy is aimed at securing non-dilutive financing and forming long-term strategic partnerships.

American Tungsten’s CEO noted that the company is advancing as a cornerstone of the region’s critical metal framework, with a mission to support secure and sustainable resource development for industrial, technology, and defense applications.
