- American Tungsten Corp. (CSE:TUNG) announced progress on its underground drilling at the historic IMA tungsten mine in east-central Idaho
- 646 metres drilled across six holes at the first D-Level station; seventh hole underway, intersecting hubnerite-bearing quartz veins
- Phase 1 program expanded with 1,173 metres of additional drilling planned plus Zero Level program increased to 2,438 metres
- American Tungsten stock (CSE:TUNG) opened trading at C$2.32
American Tungsten (CSE:TUNG) has made progress on its underground drilling at the historic IMA tungsten mine in east-central Idaho. Since early December, the company has drilled about 646 metres across six holes from the first D-Level drill station, with a seventh hole now in progress.
Key highlights
- Drilling continues to intersect quartz veins containing hubnerite (MnWO₄), a tungsten mineral. These veins occur over an area roughly 122 metres along strike and 76 metres up-dip from the D-Level
- The drift to the second D-Level drill station is complete. After finishing hole AT25-07, the rig will move there to test extensions of the vein system
- Phase 1 includes an additional 1,173 metres of drilling across nine holes from the second and third D-Level stations
- Underground rehabilitation is advancing on both the upper D-Level and the Zero Level to support drilling
- The Zero Level drill program has been expanded from 2,042 metres to 2,438 metres with a new drill station added for Phase I and II
The IMA Mine, which produced tungsten between 1945 and 1957, is located on 22 patented claims. It historically yielded about 9,974 tonnes of WO₃ concentrate. American Tungsten is now exploring the potential to restart underground mining.
Phase 1 targets five priority vein systems: No. 5, No. 7, IMA West, Eastern, and Main IMA veins. The goal is to confirm and expand historically identified tungsten veins by the end of Q1 2026.
All drill holes so far have intersected hubnerite-bearing quartz veins, but assay results are pending. Visual mineralization does not guarantee economic grades or viability.

Leadership commentary
“The initial drillholes at the IMA Project are successfully intersecting the vein system along strike of historical resources. While assay results are still pending, these early intersections reinforce the geological model and validate our disciplined, phased approach to resource expansion,” American Tungsten’s CEO, Ali Haji said in a news release on this. “Phase 1 is progressing exactly as designed, and we remain focused on advancing the targets that support our mission to become the first producer of tungsten in the United States.”
