07:56 AM EDT, 10/24/2025 (MT Newswires) -- American Tungsten ( TUNGF ) announced Friday that it has competed rehabilitation work on the D level adit at the Ima Mine in Idaho, and begun underground development in preparation for diamond drilling.

About 1,000 feet of the D level have been rehabilitated, and mobilization of the diamond drill rig is in progress, with drilling expected to commence in the middle of next month.

The company has also begun preliminary discussions and technical evaluations to assess the potential transition from a direct shipping ore (DSO) model to full-scale onsite milling.

"We remain on track to commence diamond drilling in November 2025. This program is designed to validate and expand upon historical high-grade intercepts through systematic underground drilling. The shift in our development plan - from a DSO model to establishing our own mill onsite - reflects our commitment to unlocking greater long-term value. The flowsheet program outlined by WSP will be a critical step in that journey, laying the technical foundation for engineering, economic modeling, and full-scale production," said chief executive Ali Haji.
