Locksley Resources found a new thorium and rare earth anomaly near California’s Mountain Pass mine, hinting at a larger deposit.

Locksley Resources has identified a new thorium anomaly 700 meters east of its high-grade El Campo rare earths prospect in California’s Mojave project, using ultra-high-resolution aerial surveys. The discovery, near MP Materials’ Mountain Pass mine, suggests potential for a larger, district-scale rare earth deposit, supported by radiometric data and geological patterns. The site also yielded high-grade antimony and silver samples. Ground verification and drilling are planned for 2026, with the project spanning over 490 contiguous claims and holding strategic value for U.S. critical mineral supply chains.
