Locksley Hits High-Grade 16.9pc Antimony in California

Why It Matters

Domestic antimony supply would lessen US reliance on imports and bolster national security, aligning with critical‑minerals policy.

Key Takeaways

• Surface grab samples hit 16.9% antimony
• Historical underground work showed up to 25.7% antimony
• Diamond drilling started to define resource geometry
• Antimony classified as US critical mineral for defense
• Project could supply domestic antimony, reducing import reliance

Pulse Analysis

The United States has elevated antimony to critical‑mineral status because of its essential role in flame‑retardants, alloys, and military applications. Current supply chains are heavily dependent on imports from China and a few other producers, creating strategic vulnerabilities. Federal initiatives, including the Department of Energy’s Critical Minerals program, are therefore seeking to diversify sources and encourage domestic projects that can deliver reliable, secure output.

Locksley Resources’ recent 16.9% antimony grab sample at the Mojave project provides a tangible proof point for investors and policymakers alike. The result corroborates historic underground assays that averaged 25.7% antimony, indicating a robust, high‑grade stibnite vein system that extends to the surface. By initiating a diamond‑drilling campaign, the company aims to delineate the three‑dimensional geometry of the mineralisation, generate a resource estimate, and feed data into a comprehensive 3D geological model that will guide future extraction and processing plans.

If drilling confirms a sizable, economically extractable deposit, the Mojave Antimony Mine could become a cornerstone of a US‑based antimony hub, reducing import exposure and supporting defense‑related manufacturing. The project also aligns with broader strategic goals, such as the Inflation Reduction Act’s clean‑energy and critical‑minerals incentives, potentially unlocking federal funding for metallurgical testing and infrastructure. Consequently, Locksley’s progress is likely to attract heightened interest from both the investment community and government agencies focused on securing the nation’s critical mineral supply chain.
