The Battle for Antimony: U.S. Races to Secure Domestic Supply
Securing Critical Supply Chains: The Urgency of Domestic Antimony Production

The global landscape for critical metals is shifting rapidly, and antimony is now front and center. This vital mineral, indispensable for semiconductors, military technologies, and energy storage, has become a critical national security concern following China’s export restrictions. With prices soaring and supply chains under pressure, nations like the United States are taking decisive steps to secure their antimony reserves.
The Geopolitical Impact of China’s Export Ban
In 2024, China, the dominant player in antimony production, disrupted global markets by restricting exports. This strategic move sent shockwaves through industries reliant on the mineral. Prices skyrocketed, trading at record highs of $40,000 per metric ton. The ban underscores a broader effort by China to consolidate its mineral dominance and control supply chains critical to global economies.
Antimony’s Role in National Defense
Antimony’s applications in ammunition, protective gear, and flame-resistant materials make it indispensable for military preparedness. Without a domestic supply, the U.S. faces vulnerabilities in its defense capabilities. Adam Burstein, a key figure in the Department of Defense, emphasized, “Secure sourcing of critical minerals is critical to the defense industrial base.”
Perpetua Resources: A Beacon of Hope for U.S. Supply
Perpetua Resources (Nasdaq: PPTA) is leading the charge to establish a domestic antimony supply. The company’s Stibnite Gold Project in Idaho is poised to produce 148 million pounds of antimony over six years, potentially meeting 35% of U.S. demand. CEO Jon Cherry highlighted the project’s significance: “This project is a win for national security and the environment.”
Military Metals Corporation: Diversifying North American Supplies
Military Metals Corp. (CSE: MILI) is making strategic moves to secure North America’s antimony supply. With key acquisitions in Nevada, Slovakia, and Canada, the company is positioning itself as a major player in the critical metals race. Their Last Chance Antimony-Gold Property in Nevada holds immense potential, with exploration campaigns set to begin in 2025.
United States Antimony Corporation: Strengthening Domestic Capabilities
United States Antimony Corporation (NYSE American: UAMY) operates the only primary antimony smelter in the U.S. The company’s partnerships, including a collaboration with Perpetua Resources, aim to create a robust domestic supply chain. CEO Gary C. Evans remarked, “We’re committed to ensuring the U.S. has the critical minerals it needs.”
Conclusion: Securing the Future of Antimony
As global tensions rise, securing a reliable antimony supply is crucial for economic resilience and national security. Companies like Perpetua Resources, Military Metals Corp., and United States Antimony Corporation are at the forefront of this critical endeavor. By investing in domestic projects and diversifying supply chains, the U.S. is taking significant steps to reduce its reliance on foreign sources and ensure a stable future for its critical industries.
