Vancouver, British Columbia — February 24, 2026 — Leads & Copy — American Tungsten Corp. has reported additional tungsten-silver assay results from its ongoing underground drilling program at the IMA Mine, located in Lemhi County, Idaho. The drilling program has expanded the No. 5 – No. 7 vein system by over 300 feet up-dip from the D-level and over 350 feet along strike.
According to the company, highlights from the drill results include:
- 14.2 ft grading 0.67% WO3 and 1.15 oz/t Ag in hole AT25-06
- 17 ft grading 1.28% WO3 and 3.53 oz/t Ag in hole AT25-07
Ali Haji, CEO of American Tungsten Corp., stated that the results continue to demonstrate that the IMA Mine hosts a robust and laterally extensive tungsten-silver system. He added that the consistency of mineralization strengthens the company’s confidence in the project’s scale and supports the potential restart of mining operations.
Drillholes AT26-06 and AT26-07 were drilled to expand limits of mineralization up-dip from drillhole AT25-01, as reported February 10, 2026. Both drillholes intersected the No. 5 and No. 7 veins, which have now been delineated over 300 feet up-dip from the D-level. Drillhole AT26-07 intersected the No 7 vein from 273-298 ft, but assay results for this interval of hole have not yet been received.
Drillhole AT26-05 intersected multiple broad zones of sheeted quartz veining containing hubnerite-tetrahedrite mineralization including 20.6 ft grading 0.25% WO3 and 11 ft grading 0.23% WO3. These intercepts establish continuity of mineralization over 350 south of intercepts in AT25-01. Additional drilling from locations 400 ft to the north is designed to further test the vein system up-dip and along strike.
American Tungsten has completed 11 drillholes on the D level and three drillholes on the Zero level totaling approximately 5000 feet. Drilling on the zero level is being conducted in a series of upward inclined fan holes from new drill stations in the footwall of the No.5 and No.7 vein systems. Mineralization in the principal veins consists of variable assemblages of hubnerite, scheelite, tetrahedrite, galena, sphalerite, and chalcopyrite, plus fluorite and rhodochrosite. Additional mineralization is associated with minor veins and stockworks within intervening metasedimentary host rocks.
Drilling operations are ongoing from the second D level drill station and excavation of the drift to the third drill station is underway. Currently, at least six additional holes totaling approximately 2800 feet are planned from on the D level and more holes may be added to the program based on results. Drilling and mine rehabilitation operations are also being conducted on the Zero level. Drilling on the zero level will include up to 20 holes totaling approximately 10,000 feet from three locations.
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.
American Tungsten Corp. is a Canadian exploration company focused on high-potential tungsten and magnetite assets in North America. The Company is advancing the IMA Mine Project in Idaho to commercial production, addressing critical metal scarcity in North America. The Company’s IMA Mine Project is a historic and high-quality underground tungsten past-producing property on private-patented land well above the water table with significant infrastructure. The Company holds an exclusive option to acquire full ownership (subject to a 2% royalty) and has expanded its land position with 113 additional federal claims covering nearly 2,000 acres.
