US Antimony Corp Jumps 22% After Securing $245 Million Sole-Source Defense Deal

TradingKey - United States Antimony Corporation (USAC) announced Tuesday that it has signed a five-year, sole-source contract with the U.S. Defense Logistics Agency (DLA) worth up to $245 million to supply antimony metal ingots to the U.S. National Defense Stockpile.

The high-profile contract ignited strong investor confidence, sending USAC’s stock soaring more than 20% intraday on Tuesday and pushing its market capitalization above $1 billion.

The agreement is an “indefinite-delivery, indefinite-quantity” (IDIQ) contract, with the core purpose of replenishing the defense stockpile’s inventory of antimony metal ingots.

“It’s incredibly meaningful for all our employees to play such a strategic role in strengthening our nation's defense readiness," USAC CEO Gary C. Evans said in a statement. He added that the company would immediately begin fulfilling the contract from its North American facilities, with the first shipment expected this week.

The contract is the result of months of intensive negotiations and further deepens the partnership between USAC and the U.S. Department of Defense — a relationship that has accelerated significantly since late 2024.

As the operator of two of only a few antimony smelters in North America, USAC holds a uniquely advantageous position in executing this strategic contract. The company stated that its North American smelting facilities are fully capable of producing antimony metal ingots that meet the U.S. government’s stringent specifications.

To support long-term supply and enhance U.S. supply chain resilience, USAC is actively expanding its raw material sourcing channels. The company is procuring antimony ore globally while simultaneously advancing domestic project development.

Recently, USAC has commenced mining operations at its Alaska site, where preliminary exploration data indicate high-grade ore. Meanwhile, development of its mineral rights in Montana is also progressing steadily.

In its announcement, USAC specifically emphasized that all other potential antimony suppliers — whether domestic or overseas — are at least three years away from achieving commercial-scale production, and it remains uncertain whether they can consistently meet the strict specifications required for defense applications.

Antimony metal is highly valued for its critical role in the defense industry and is widely used in munitions, military batteries, flame retardants, and specialty chemical manufacturing. Pentagon officials have previously identified antimony as a “vulnerable link” in the U.S. industrial base. In today’s complex and volatile geopolitical environment, ensuring a stable supply of critical minerals is of irreplaceable importance to national security and economic independence.
