American Tungsten Corp. has surpassed 30,000 feet of completed drilling at the Ima Mine in Lemhi County, Idaho, generating more than 5.5 miles of core since December 2025.

Recent assays from the underground program include hole AT26-43, which intersected 14.8 feet grading 0.470% WO₃ and 1.24 oz/t Ag in the No. 7 vein, alongside 6.7 feet grading 0.547% WO₃ and 2.38 oz/t Ag in the No. 5 vein. On the Zero Level, hole AT26-39 returned 9.4 feet grading 0.802% WO₃ and 0.59 oz/t Ag within the historic 41R vein structure. Surface drilling also yielded deeper intercepts, including 10.6 feet grading 0.955% WO₃ and 1.14 oz/t Ag in hole AT26-48S adjacent to the Ima Stock.

“Crossing the 30,000-foot drilling threshold marks another important step in defining the scale and continuity of the IMA Mine mineral system,” said Austin Zinsser, Vice President of Exploration. “The latest results not only expand the known extent of the No. 5 through No. 7 vein array, but also confirm the historic 41R vein and identifies additional tungsten-bearing zones beyond previously mined areas. Together, these intersections continue to reinforce our view that IMA hosts a significantly larger mineralized system than previously recognized, while highlighting the considerable exploration potential that remains both adjacent to and beyond the historic mine workings.”

Assays for additional completed drillholes are currently pending at the IMA Mine.
