United States Antimony Corp (NYSEAMERICAN: UAMY) has made a move to expand its global footprint in the critical minerals sector.
The company announced on Sunday that it has submitted a confidential, non-binding proposal to acquire all shares of Australia-based Larvotto Resources Limited (ASX: LVR) (OTCMKTS: LRVTF) through a scheme of arrangement under Australian law.
Under the proposal, Larvotto shareholders would receive six USAC shares for every 100 Larvotto shares, representing a significant premium compared with Larvotto’s last equity raise on July 25, 2025, and recent trading levels.
The deal remains subject to shareholder approval, regulatory clearance, and the signing of a binding agreement. However, USAC has already purchased about 10.0 per cent of Larvotto’s issued shares on the open market, making it the company’s largest single shareholder.
Chairman and chief executive officer Gary C. Evans said the proposed combination reflects USAC’s commitment to building a world-class critical minerals company. He added that the merger offers Larvotto investors the chance to join a stronger, more diversified organization with global reach and financial stability.
In addition, Evans emphasized the shared strategic and cultural values between the two firms, noting that the merger would enhance both technical expertise and production capacity. Furthermore, he expressed confidence that the deal would create long-term value for all shareholders.
USAC, a leading producer and processor of antimony, zeolite, and other critical minerals, has appointed Jett Capital Advisors and Henslow as financial advisers. The company also named Ashurst as its Australian legal counsel and Duane Morris as its U.S. legal counsel.
Both companies expect continued discussions as the proposal advances toward potential completion.

Department of defense providing supply chain assistance
The United States continues to take decisive action to reduce its reliance on China for critical minerals essential to defense and technology. Through a combination of regulatory reforms, federal investments, and partnerships with domestic producers, Washington is working to secure long-term access to strategic materials. One of the most important initiatives supporting this effort is the FAST-41 program, which streamlines the permitting process for projects considered vital to national security.
Perpetua Resources Corp (TSE: PPTA) (NASDAQ: PPTA) is one of the companies benefitting from this framework. Its Stibnite Gold Project in Idaho has received FAST-41 designation, giving it priority treatment during environmental and regulatory reviews. The project holds particular importance because it contains significant deposits of antimony, a mineral critical for U.S. defense manufacturing. Antimony is used in munitions, flame retardants, and other advanced defense technologies. While it is not officially classified as a “critical mineral,” it remains on the Department of Defense’s essential minerals list.
In addition, Perpetua Resources has received funding from the U.S. Department of Defense to help re-establish a domestic supply chain for antimony. The department has been pursuing contracts with qualified American producers to ensure long-term access to these minerals. Furthermore, multi-year procurement agreements are helping the government maintain strategic stockpiles that might otherwise depend on imports from foreign suppliers. These steps aim to reduce the risk of supply disruptions and to protect industries vital to defense and advanced manufacturing.

Policymakers view domestic producers as strategic partners
China currently dominates global antimony production, and its export restrictions have intensified U.S. efforts to build local capacity. Consequently, American policymakers have started to view domestic producers as strategic partners in strengthening supply chains. The renewed focus on antimony illustrates the goal of diversifying the nation’s mineral base and reducing exposure to geopolitical risks.
NevGold Corp (CVE: NAU) (OTCMKTS: NAUFF) (FRA: 5E50) is another company that could play a future role in this shift. The Vancouver-based explorer recently reported high-grade oxide antimony discoveries at its Limousine Butte Project in Nevada. Early drilling results showed strong mineral recovery potential from surface, signalling economic viability. Additionally, the company’s work aligns with the government’s push to identify new domestic sources for defense related materials.
If supported by federal initiatives, such discoveries could help position NevGold as a valuable contributor to the U.S. supply chain. Meanwhile, the broader effort to establish a self-sufficient minerals sector continues to gather momentum. Programs like FAST-41 and Defense Department partnerships, the United States is building a foundation for a secure and sustainable resource future that is less dependent on foreign control and more capable of supporting national security needs.
