Acquisition Secures Processing Footprint in Idaho

Data source: Company update
The two historical tungsten ore stockpiles are estimated at 2,000 tonnes, though this figure remains a non-JORC compliant historical and foreign estimate. Until a Competent Person completes further evaluation, this tonnage cannot be officially classified as a resource or reserve, highlighted the company update.
Strategic Significance of the Acquisition

Data source: Company update
Furthermore, the company believes that there are additional opportunities to extend known tungsten mineralisation in and around the historic Golden Gate Tungsten Mine. To evaluate the potential areas, the company plans to integrate ground-based exploration, geophysical surveys, analysis of historical data and other technical assessment methods to design and implement a structured exploration program.
Exploration and Development Plans Underway
The company has retained former Golden Gate Mine geologist David R. Hembree, CPG, to help drive the next phase of exploration and development activities. Upcoming work will focus on metallurgical testing on existing tungsten stockpiles and processing studies, alongside detailed engineering reviews and refurbishment assessments. The company will also advance permitting and development pathways, assess the near-term processing potential of existing tungsten stockpiles, and continue discussions aimed at establishing strategic partnerships and potential offtake agreements.
A drill program is expected to begin in the second quarter of 2026.
