AMERICAN TUNGSTEN RAMPS-UP EXPLORATION OPERATIONS; INITIATES 35,000 FT SURFACE AND UNDERGROUND DRILLING PROGRAM AT IMA MINE

American Tungsten Corp. has made a significant expansion of exploration activities at the Ima mine property in Lemhi county, Idaho. The company has two surface drill rigs on site, in addition to two underground drill rigs. Thirty-five thousand feet of drilling is currently planned on the property, including 33 underground holes and 20 surface holes. In addition, a new crosscut is being developed on the D-level to establish underground drill stations to extend previously identified mineralization.

"While advancing our initial tailings-focused program, we are now accelerating into the next phase of drilling, positioning the company for a steady stream of results across multiple work programs," stated Ali Haji, chief executive officer of American Tungsten. "With four rigs currently operating across surface and underground, this expanded campaign is designed to extend known mineralization and test high-priority targets adjacent to historic workings. The scale and pace of this program underscore our confidence in the Ima mine and our focus on systematically unlocking its full potential through a disciplined, multiphase exploration strategy."

The expanded drilling program has multiple objectives:

• Expand limits of mineralization in the No. 5 to No. 7 vein system above the D-level from a newly developed footwall crosscut;
• Establish additional along-strike continuity of the D-level vein system to the south through surface drilling, following up on previously announced sampling of surficial vein exposures;
• Confirm and expand mineralization in historical drilling and sampling from the second zero-level drill station targeting tungsten and molybdenum mineralization occurring at the upper intrusive contact;
• Assess continuity of mineralization in the western vein system from surface and underground holes, as initially intersected in AT26-16 and historical 2008 drill holes; and
• Define lateral extents of the main Ima vein system below the lower levels of the mine through surface drilling, as intersected in initial zero-level drill holes.

Rockhead Consulting LLC has been contracted to provide additional drilling services and has mobilized two track-mounted surface core rigs to site. One is currently operating, and the second will start drilling by the end of May. To date, Rockhead Consulting has completed 38 drill holes totalling over 16,500 feet and driven over 660 feet of drift at the Ima mine.

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 metric thermal units of WO3, and was subsequently explored for molybdenum and tungsten by various operators between 1960 and 2010 (National Instrument 43-101 technical report on the Ima mine, Patterson, Idaho, United States, page 29; B. LeBlanc, PEng (2025), A-Z Mining Professionals, dated June 6, 2025, on SEDAR+ for American Tungsten). American Tungsten is currently conducting an exploration drill program and assessing potential for the restart of underground tungsten mining operations at the Ima mine.

About American Tungsten Corp.

American Tungsten is a Canadian-based exploration and development company focused on advancing the Ima mine project, a high-quality, private-patented, past-producing underground tungsten mine located in Idaho, United States. The company's strategy is centred on advancing the Ima mine back into commercial production through a clearly defined, phased development approach. Phase 1 involves the evaluation and potential processing of existing surface tailings, providing a lower-capital pathway to near-term production. Phase 2 is focused on the rehabilitation and restart of the historic underground mine, leveraging the site's extensive existing infrastructure and historical production profile.

With tungsten recognized as a critical metal for defence, industrial manufacturing and advanced technologies, American Tungsten is focused on re-establishing domestic tungsten production and supporting North American supply chain security.
