American Tungsten intercepts 125 feet tungsten-silver mineralization

Expanding Mineralization Beyond Historic Veins- Vancouver, British Columbia--(Newsfile Corp. - June 23, 2026) - American Tungsten Corp. (TSXV: TUNG) (OTCQB: TUNGF) (FSE: RK90) ("American Tungsten" or the "Company) today, reported positive results from drillholes completed on the zero level of the Ima Mine, Lemhi County, Idaho. "These results from hole AT26-21 represent a significant step forward in our understanding of the Ima system. The hole intersected over 125 aggregate feet of tungsten-silver mineralization, including multiple higher-grade zones, confirming the presence of a meaningful secondary vein system east of the historic workings.

Importantly, this mineralization occurs outside our initial target area, reinforcing the broader scale potential of the system and demonstrating that Ima remains open for expansion in several directions," said Ali Haji, CEO of American Tungsten. "This progress builds real momentum as we continue to show that the Ima Mine is evolving into something much larger than historically defined. Our goal is clear: keep pushing, expand the system, and deliver a meaningful resource by the end of the third fiscal quarter." Drill Results Highlights: Hole AT26-21 intersected over 125 feet of aggregate tungsten-silver mineralization in a secondary vein system adjacent to the main Ima vein.

Hole AT26-25 intersected broad intervals of quartz-molybdenite mineralization and tungsten bearing quartz veins within the Ima granitic stock effectively extending the known limits of historically defined molybdenum mineralization. Additional holes drilled on the zero level also intersected significant tungsten mineralization east of the mine. Highlights from hole AT26-21 include: 76.7 feet grading 0.327% WO3 (estimated at 32 feet true width) including multiple discrete intercepts over 0.6% WO3, and 26.2 feet grading 0.41% WO3 (estimated at 11 feet true width), including multiple intercept
