What's Happening?
Locksley Resources has announced significant assay results from its initial diamond drilling program at the El Campo prospect within the Mojave Project in California. The results indicate the presence of high-grade neodymium and praseodymium-enriched
light rare earth element mineralisation. Located approximately 5.5 kilometers southeast of MP Materials' Mountain Pass Mine, the only operational rare earth mine in the U.S., El Campo's drill-hole ECDD0002 yielded a peak value of 6.03% total rare earth oxide (TREO) over 0.7 meters. The drilling confirmed that rare earth mineralisation continues below the surface and remains open both at depth and along strike within the wider El Campo corridor. These findings suggest the potential existence of a larger carbonatite system at depth, similar to the Mountain Pass-style mineralisation.
Why It's Important?
The confirmation of high-grade rare earth mineralisation at El Campo is significant for the U.S. rare earth supply chain, which is crucial for the production of permanent magnets and various advanced technologies. Neodymium and praseodymium, which account for around 25% of the TREO in key intercepts, are critical components in the manufacturing of these magnets. The development of domestic rare earth resources is vital for reducing U.S. dependence on foreign sources, particularly from China, which currently dominates the global rare earth market. This discovery could enhance the U.S.'s ability to secure a stable supply of these essential materials, supporting technological advancements and national security.
What's Next?
Locksley Resources plans to continue its exploration efforts at the Mojave Project, focusing on refining the extent and lithostructural controls on the rare earth mineralisation. The company intends to integrate the results into ongoing drill targeting plans, supported by a high-resolution ground scintillometer survey across the entire permit footprint. These efforts aim to further delineate the resource and assess its economic viability, potentially leading to the development of a new rare earth mining operation in the U.S.
