American Tungsten Corp. Engages United Supply Co. to Secure

Strategic Offtake and U.S. Defense Sector Relationships Amid

Growing National Security Concerns & Announces New Board

Appointment

Vancouver, BC, March 10, 2025 – American Tungsten Corp. (CSE:TUNG)

(OTCQB:DEMRF) (FSE:RK9) (“American Tungsten ” or the “ Company”) is pleased to

announce that it has engaged United Supply Co. (“United Supply”), a specialized advisory group

focused on securing offtake agreements and stra tegic partnerships within the U.S. defense

manufacturing sector. This initiative is a direct response to increasing concerns over the domestic

supply of tungsten – a critical mineral essentia l for national defense – following China’s recent

ban on tungsten exports and the U.S. Governme nt’s policy shift towards onshoring domestic

production and supply of critical minerals.

United Supply provides strategic support for defense and defense-adjacent companies, specializing

in sales, manufacturing execution, and procurement. With over $75 million in closed defense deals,

United Supply connects buyers with mission-critical solutions and secures key contracts. United

Supply also oversees manufacturi ng operations from concept to production, ensuring efficient

execution. By integrating at any stage of a co mpany’s operations – whether providing high-level

strategy or direct execution – United Supply strengthens the resilience of domestic manufacturing

and supply chains, supporting the long-term sustainability of the U.S. defense industry.

The Company’s engagement with United Supply aligns with the latest policy direction outlined by

President Donald Trump, who reaffirmed his administration’s commitment to bolstering domestic

production of critical minerals. American Tungsten is seeking to position itself at the forefront of

this effort by advancing the development of secure, onshore tungsten sources in the United States.

Tungsten is a vital material for defense app lications, with unparalleled hardness and high-

temperature resistance, making it indispensa ble for armor-piercing ammunition, missile

components, and aerospace manufacturing. The U. S. Department of Defense and the Defense

Industrial Base Consortium, of which the Company is an active member of, classifies tungsten as

a critical mineral. Yet, the country remains heav ily reliant on imports – primarily from China,

which dominates over 80% of global supply . The recent ban on tungsten exports by China

underscores the need to establish a stable, Nort h American supply chain to safeguard national

security interests.

“We’re excited to have United Supply in our corner as we look to advance discussions and form

strategic relationships with key United States government agencies. The United States can no

longer afford to depend on foreign sources for ma terials critical to its national defense,” said

Murray Nye, CEO of American Tungsten. “China ’s recent export restrictions on tungsten are a

wake-up call, and we are taking decisive action to develop a secure domestic supply. With the

Biden administration previously prioritizing critical minerals and now President Trump doubling

down on the urgency of U.S. production, we believe the time is now to establish American tungsten

independence.”

With United Supply now engaged, the Company w ill look to accelerate discussions with U.S.-

based defense manufacturers and government stak eholders to secure long-term contracts that

support the re-shoring of tungste n production. Through advancing its tungsten project, the IMA

Mine, the Company is committed to potentially playing a leading role in ensuring that the United

States has a reliable and secure supply of this essential mineral, reducing dependency on foreign-

controlled supply chains.

The IMA Mine is a past produc ing underground tungsten mine s ituated on 22 patented claims

located in East Central Idaho. Between 1945 and 1957, the property pr oduced approximately

199,449 MTUs of WO3 and was subsequently explored for molybdenum and tungsten by various

operators between 1960-2008(1).

Board Appointment

The Company is also pleased to announce the appoi ntment of Mr. Austin Zi nsser to its Board of

Directors effective March 7, 2025. Mr. Zinsser ha s over 15 years of experience in applied

member of SME.

Gold Project, and has worked on other critical mineral projects in the western U.S. as an
