AMERICAN TUNGSTEN ADVANCES METALLURGICAL AND INFRASTRUCTURE STUDIES AT THE IMA MINE

American Tungsten Corp. has reached several milestones toward advancing the Ima mine, the company's past-producing tungsten mine located in Idaho, United States, including: the launch of a comprehensive metallurgical testing program led by Bomenco Minerals Engineering Corp. and SGS Laboratories and the commencement of geotechnical investigations by NewFields MTDs to support the design of the mine's tailings and waste rock storage facilities. These programs will provide critical technical data to support future engineering, environmental and mine development studies.

Metallurgical testing program -- Ima mine processing studies

American Tungsten has engaged Bomenco Minerals Engineering to manage a comprehensive metallurgical testing program for the Ima mine. Matt Bolu, MSc, PEng, principal engineer at Bomenco, will oversee all metallurgical activities and co-ordinate testing through SGS Laboratories, a globally recognized provider of mineral testing and process development services.

The program is designed to develop technically and economically viable tungsten recovery processes and generate data required for future engineering and economic evaluations. Results from the program will support the company's continuing assessment of potential processing routes and contribute to the design of a future processing facility for the mine.

Bomenco brings extensive experience in metallurgical process development and project evaluation within the mining industry while SGS is recognized globally for its technical expertise in mineral processing and metallurgical testing. Together, the organizations will provide the technical framework necessary to advance processing studies at the Ima mine.

Geotechnical program -- surface infrastructure design

American Tungsten has retained NewFields MTDs to undertake geotechnical investigations supporting the design and evaluation of the mine's proposed tailings storage facility and waste rock storage facility.

The scope of work will include site characterization, geotechnical testing, engineering assessments and design recommendations that will support responsible mine planning and future infrastructure development. The studies will be completed in accordance with industry best practices and are intended to support future engineering and environmental planning activities.

Information generated through the program will form an important component of future mine design and permitting efforts while helping establish the technical foundation for long-term infrastructure planning at the mine.

Ali Haji, chief executive officer of American Tungsten, stated: "The metallurgical and geotechnical programs represent important milestones in advancing the restart of the Ima mine. Results from the metallurgical program will support process flowsheet optimization, recovery and future engineering studies, while the geotechnical work will provide critical design criteria for tailings and waste rock storage infrastructure. Together, these programs are intended to reduce technical risk and support the company's phased strategy of processing existing surface tailings and ultimately restarting the historical underground operations of 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 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.
