We’ve commenced diamond drilling at our Tennessee Mountain #Tungsten Project in Nevada, advancing the evaluation of a potential company-controlled tungsten feedstock source within our U.S. critical minerals strategy.

Two Energold diamond rigs are on site, operating double shifts, to complete approximately 3,000m of HQ diamond drilling across 17 approved drill pads. The program is designed to verify historical mineralisation and test potential extensions along strike and at depth.

Outstanding historical high-grade tungsten drill results include 24.9m at 0.65% WO₃, including 10.67m at 0.91% WO₃, and 18.38m at 0.72% WO₃, including 13.17m at 0.91% WO₃.

Tennessee Mountain is being evaluated as a potential future feedstock source for the Del Sol Refinery’s proposed ammonium paratungstate (APT) circuit, alongside third-party concentrate and offtake opportunities.

Our Mineral Intelligence Engine™ framework will assess potential feedstock sources against Del Sol Refinery APT circuit feed requirements to support commercial sourcing decisions.

Drilling is scheduled to run to December 2026, subject to weather, with assay results expected in Q1 2027.
