Locksley Resources Mojave Project: Critical Antimony and Rare Earth Development

Understanding the Locksley Resources Mojave Project and Its Strategic Importance

The Locksley Resources Mojave Project represents a pivotal development in America's quest for critical mineral independence, targeting both antimony and rare earth elements in California's mineral-rich Mojave Desert. This dual-commodity exploration venture has captured attention from federal financing agencies and policy makers as the United States seeks to reduce dependence on foreign mineral supplies, particularly from China.

Located in Inyo County, California, the project spans 20.9 square kilometres of mineral claims positioned strategically adjacent to the historic Mountain Pass Mine complex. This proximity to established rare earth infrastructure provides potential operational synergies and access to existing processing capabilities, transportation networks, and technical expertise developed over decades of rare earth operations in the region.

The project's significance extends beyond its geological potential. With antimony imports comprising 100% of U.S. consumption and China controlling approximately 80% of global antimony supply, the Mojave Project addresses critical national security vulnerabilities. Similarly, while the United States has domestic rare earth mining through Mountain Pass, the concentration of processing capabilities in China creates supply chain risks for materials essential to defence systems, clean energy transition security technologies, and advanced manufacturing.

Strategic Location and Geological Advantages

The project's positioning within a proven geological district provides substantial advantages for exploration and potential development. The Mojave Desert region has a documented history of rare earth and base metal mineralisation, with the nearby Mountain Pass Mine serving as the only operating rare earth mine in the United States.

Proximity Benefits and Infrastructure Access

The strategic location offers several operational advantages:

• Processing Infrastructure: Potential access to rare earth processing facilities and expertise
• Transportation Networks: Established logistics routes for mineral transport
• Technical Knowledge: Access to geological and metallurgical expertise from neighbouring operations
• Regulatory Experience: Understanding of local permitting and environmental requirements

Geological Context and Mineralisation Potential

Surface sampling programmes have identified promising mineralisation across both target commodities. Antimony concentrations have reached 46% Sb in select samples, while rare earth rock chip assays have returned values up to 12.1% total rare earth oxides (TREO) with neodymium-praseodymium concentrations of 3.19% in individual samples.

These preliminary results, while encouraging, represent surface expressions that require subsurface validation through systematic drilling programmes. The Bureau of Land Management has approved drilling permits for the Desert Antimony Mine portion of the project, indicating regulatory pathway progress and environmental compliance achievements.

Addressing Critical U.S. Supply Chain Vulnerabilities

The Antimony Supply Crisis

Antimony represents one of the most acute supply chain vulnerabilities in U.S. critical minerals policy. The metal serves essential functions in flame retardants, battery technologies, military applications, and semiconductor manufacturing. Furthermore, the strategic antimony loan developments demonstrate growing federal recognition of this supply gap.

The absence of domestic antimony production creates vulnerabilities across multiple sectors. Defence contractors rely on antimony for munitions and protective equipment, while technology manufacturers require the metal for specialised alloys and flame retardant applications. Any supply disruption could cascade through American manufacturing and defence capabilities.

Rare Earth Strategic Positioning

While the United States operates the Mountain Pass Mine, the nation remains heavily dependent on Chinese processing capabilities for rare earth elements. In addition to antimony concerns, escalating US-China trade tensions highlight the urgency of developing domestic alternatives.

Critical Applications for Targeted Elements:

• Neodymium-Praseodymium: Permanent magnets for electric vehicles, wind turbines, and defence systems
• Heavy Rare Earths: Advanced electronics, missile guidance systems, and precision instruments
• Processing Synergies: Potential integration with existing Mountain Pass operations
• Supply Chain Security: Reduced dependence on foreign processing capabilities

Technical Progress and Development Milestones
