American Tungsten Announces Strategic Advancements in IMA Mine

Rehabilitation and Exploration Program

Vancouver, BC, July 30, 2025 – American Tungsten Corp. (CSE:TUNG) (OTCQB:DEMRF)

(FSE:RK9) (“American Tungsten” or the “Company”) is pleased to provide a corporate update

on its ongoing efforts to reha bilitate the historic IMA Mine in Patterson, Idaho and advance its

expanded drilling programme. This programme is a critical step toward unlocking long-term value

and reinforcing the Company’s position to play a vital role in ore supply of tungsten in North

America for defense, industrial and technology applications.

“As global demand for secure critical metals inte nsifies, American Tungsten continues to build

strategic momentum, reinforcing its role as a cornerstone of North America's tungsten supply

chain. The Company’s dual approach—revitalizi ng a historically rich asset while defining a

maiden resource, positions American Tungste n at the forefront of sustainable resource

advancement. Following several months of detailed environm ental assessment, engineering

design, and community engagement, American T ungsten is entering the next phase of its IMA

Mine rehabilitation strategy. With a full y-funded programme, the Company has secured

preliminary approval for its site remediation plan, which focuses on restoring the existing

infrastructure to support future production goals,” said Ali Haji, CEO of American Tungsten Corp.

IMA Mine Project entering next phase of rehabilitation strategy

About the IMA Mine Project:

The IMA Mine is an advanced, readily permittable, past producing tungsten-molybdenum property

situated in the Idaho porphyry belt and located on patented mining claims. American Tungsten has

an immediate opportunity to ad vance strong identifi ed molybdenum-bearing intrusion targets

located below historic tungsten production area through step-out drilling program.

The IMA mine is a past-producing underground t ungsten mine situated on 22 patented claims

located in east central Idaho. Between 1945 and 1957, the property produced approximately

199,449 metric ton units of tungst en trioxide (WO3). It was subsequently explored for

molybdenum and tungsten by various operators between 1960 and 2008.

The mine was last in production in 1957 with significant underground rehabilitation and

development conducted on the zero level by Midwest Oil and Inspiration Development Co. in the

1960s and late 1970s, including development of new drifts around unstable areas and construction

of underground drill stations. Current rehabilita tion efforts aim to re-establish safe access to

previously rehabilitated areas and underground drill stations.

American Tungsten has contracted Rockhead Consulting LLC to perform initial underground

rehabilitation of the mine. Rockhead Consulting is an established underground mining contractor

based in Sheridan, Montana, with over 40 year s experience and an emphasis on safety and

productivity. Rockhead provides a wide range of mine development services including engineering

and construction of tunnels, decl ines, raises, shaft rehabilitati on and de-watering projects of

various sizes and complexity.

Key Strategic Priorities

IMA Mine Rehabilitation Underway:

 Site remediation commenced, focused on restoration and long-term sustainability;

 Work on the IMA project will begi n with rehabilitation of the zero level drift to assess

condition of underground infrastructure, estab lish access to underground drill stations on

the zero level, and inform access to the upper D level for underground exploration drilling;

 Continue assessment of existing portals in collaboration with mining engineers to

determine rehabilitation needs; and

 Finalize development plan and scope of work including necessary rehabilitation

upgrades, confirmatory infill drilling, and metallurgical testing.

Define IMA Mine Resources:

 Complete exploratory drilling to expand tungsten resources and assess underlying

molybdenum porphyry system;

 Over 6,000 feet of underground diamond drilling planned in Q3-2025 across geological

targets to bolster American Tungsten’s long-term supply capabilities by enhancing

resource definition;

 Compile and validate historical information;

 Define and finalize scope of work to complete a mineral resource estimate in Q3-2025;

and

 Digitize historical drilling records, assay data / production volumes, and construct digital

geological models.

Foster and Secure Key Strategic & Financial Partnerships:

▪ Continue discussions to secure key strategic partnerships and non-dilutive financing with

the U.S. Department of Defense and U.S. Department of Energy;

▪ Expand shareholder base and introduce new long-term, growth-oriented capital partners

to reinforce financial sustainability and future expansion; and

▪ Received conditional approval for listing on the TSX Venture Exchange, marking a

significant advancement for the Company and reflecting its continued corporate growth

and aligning with the strategic development of our tungsten asset.
