China’s Antimony Export Ban Sparks Concerns for US Defense and Tech Industries

The ban is part of a broader move by Beijing to leverage its control over critical minerals in the ongoing US-China trade conflict. With China dominating nearly 50% of global antimony mining and 80% of its production, the United States now faces a precarious reliance on foreign sources for this essential material.

For major defense contractors like Lockheed Martin (NYSE: LMT), the world’s largest, the implications are profound. The company’s key programs, including the F-35 fighter jet and missile defense systems, rely heavily on stable access to advanced materials like antimony. This situation highlights the urgent need for diversification of supply chains and reduced dependency on potentially adversarial nations.

In response to this crisis, several companies are stepping up efforts to secure alternative sources of antimony and other critical minerals. Military Metals Corp. (OTCQB: MILIF) (CSE: MILI) has emerged as a promising player in this space, focusing on acquiring and developing mineral-rich properties in stable jurisdictions across Europe and North America. The company’s recent acquisitions in Slovakia, including the Trojarová, Tienesgrund, and Medvedi projects, position it to potentially become a significant supplier of antimony and gold.

Perpetua Resources Corp. (Nasdaq: PPTA) is advancing the Stibnite Gold Project in Idaho, which could become the only domestic source of mined antimony capable of meeting U.S. defense requirements. The company has secured significant funding under the Defense Production Act to support the project’s development, emphasizing its strategic importance to national security.

United States Antimony Corporation (NYSE: UAMY) is also playing a crucial role as the only North American antimony smelter. The company has expanded its presence in Alaska’s Tok region, securing additional mining claims to develop domestic sources of critical minerals. USAC’s integrated business model and expansion initiatives position it to address growing demand effectively while supporting national priorities.

The antimony export ban has exposed vulnerabilities in the U.S. supply chain for critical minerals, prompting a reevaluation of sourcing strategies across industries. As geopolitical tensions continue to shape resource markets, companies focused on developing secure domestic supplies of antimony and other critical minerals are likely to play an increasingly important role in ensuring national security and technological innovation.

This situation serves as a wake-up call for policymakers and industry leaders alike, highlighting the need for investment in domestic mineral exploration, processing capabilities, and the development of alternative sources. As the global landscape of critical mineral supply continues to evolve, the ability to secure stable access to these resources will be crucial for maintaining technological leadership and national security in the years to come.
