The United States Antimony Corporation (USAC) has received $27m in funding from the Department of War (DoW) under Title III of the Defence Production Act (DPA) for critical domestic materials extraction.
This investment aims to boost, innovate and expand the extraction, processing and refining of critical materials.

It is part of a broader initiative by the US Government to increase the production of essential minerals, as outlined in Executive Order 14241 issued in March 2025.
The funding will support USAC’s efforts to modernise and expand its Montana facility to enhance the production of antimony, essential for flame retardants, batteries, munitions and other defence uses.
Additionally, it will help USAC establish antimony excavation and extraction operations in Alaska with the aim of securing domestic feedstock.
This grant is part of three investments totalling $58.5m made by the DPA Purchases Office since the start of fiscal year 2026.

Global concerns have heightened due to China’s recent ban on exporting critical minerals including antimony, exacerbating supply chain vulnerabilities.
The US faces an urgent need to rebuild its domestic capacity for antimony production to ensure military readiness and long-term supply chain stability.
In response to these challenges, USAC received a sole-source contract by the US Defence Logistics Agency (DLA) Strategic Materials, valued at up to $245m.
USAC’s expertise allows it to produce several strategic derivatives of antimony.
Antimony trioxide is utilised in flame retardants and various polymers, antimony trisulfide is used in munitions and solar panels, and antimony metal serves sectors like semiconductors and night vision technologies.
USAC chairman and CEO Gary Evans said: “The US has historically relied too heavily on foreign sources for antimony, despite its role in munitions, fire protection and emerging energy technologies. As the only domestic processor of antimony, USAC is uniquely positioned to further support our nation’s strategic and commercial needs.
“This additional financial support announced today will allow us to continue accelerating our current expansion and in our operations as the only fully integrated antimony miner and producer located in the world, outside of China and Russia.”
