Revolutionizing Antimony Processing: Inside Locksley Resources' Mojave Project Strategy
Antimony processing is undergoing a transformative shift in the United States, with Locksley Resources' Mojave project positioned at the forefront of this revolution. The strategic partnership with Rice University marks a pivotal development in addressing critical supply chain vulnerabilities while establishing domestic processing capabilities for this essential mineral.
What Makes Antimony a Critical Strategic Mineral?
Antimony has emerged as a vital resource in modern industrial applications, with particular significance for national security and emerging technologies. Understanding its importance provides context for why the Mojave project represents such a strategic opportunity.
The Strategic Importance of Antimony in Modern Applications
Antimony serves as a crucial component across multiple strategic sectors, with defense applications representing one of its most critical uses. The metal plays an essential role in ammunition production, where it hardens lead bullets and improves their performance characteristics. Beyond ammunition, antimony finds application in explosives, propellants for missiles and rockets, and various components of armored vehicles.
The mineral's flame-retardant properties make it indispensable in military equipment, aircraft, and protective gear. These flame-retardant applications extend to civilian sectors, including building materials, electronics, and transportation safety systems.
In the rapidly evolving energy sector, antimony compounds are increasingly utilized in certain battery technologies and energy storage systems. As renewable energy integration accelerates, these applications are expected to grow in importance over the coming decade.

Current Supply Chain Vulnerabilities
The antimony supply landscape presents significant challenges for the United States and its allies. According to USGS data, China produced approximately 48,000 metric tons of antimony in 2022, representing about 55% of global production, which totaled around 87,000 metric tons.
More concerning is that approximately 95% of refined antimony supply currently comes from countries outside U.S. alliance networks. This extreme dependency creates substantial supply chain vulnerabilities, especially considering antimony's critical minerals directive and applications in defense systems and infrastructure.
The Trump administration recognized these vulnerabilities by designating antimony as a critical material under executive orders focused on increasing domestic mineral production and reshoring supply chains. This designation acknowledges antimony's strategic importance and the risks associated with its current supply structure.
The absence of domestic processing capacity represents perhaps the most significant vulnerability. Currently, the United States lacks any commercial-scale antimony processing operations, creating a critical gap in the domestic supply chain even when raw materials might be available.
How Is Locksley Resources Addressing the Antimony Processing Gap?
Locksley Resources has developed a comprehensive strategy to address the antimony processing deficit through its Mojave project. This approach combines strategic antimony insights with innovative processing solutions through academic partnerships.
