American Tungsten Advances Underground Drill Program at IMA Mine

Vancouver, British Columbia--(Newsfile Corp. - January 13, 2026) - American Tungsten Corp. (CSE: TUNG) (OTCQB: TUNGF) (FSE: RK90) ("American Tungsten" or the "Company) is pleased to announce an update on advancing the underground drill program at the IMA mine. To date, 2,120 feet of drilling consisting of six holes has been completed.

Drill Program Highlights: at the first D-Level drill station to be completed

• 2,120 feet across six holes completed since early December, with the final hole from the first D-Level drill station now underway;

• Drilling continues to intersect quartz veins with hubnerite (MnWO₄) mineralization; vein intersections occur over an area 400 feet along strike and 250 feet up-dip from the D-level;

• Drift to the second D-Level drill station completed; the rig will be moved after AT25-07, which will test the up-dip extension;

• An additional 3,850 feet of drilling planned across nine holes from the second and third D-Level drilling stations as part of the Phase 1 Program;

• Underground rehabilitation advancing on both, the upper D Level and the Zero Level, to support ongoing drilling activity; and

• Zero Level drill program expanded from 6,700 to 8,000 feet with the addition of a new drill station for Phase I and II Programs.

"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. 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," said Ali Haji, CEO of American Tungsten Corp.

ABOUT THE IMA MINE

The IMA Mine is a past producing underground tungsten mine situated on 22 patented claims located in East Central Idaho. Between 1945 and 1957, the property produced approximately 199,449 MTUs of WO3 and was subsequently explored for molybdenum and tungsten by various operators between 1960-2010. American Tungsten Corp is currently conducting an exploration drill program and assessing potential for re-start of underground tungsten mining operations at the IMA Mine.
