Lockley Resources Limited, operating under the stock symbols ASX: LKY and OTCQX: LKYRF, has made crucial advancements in its exploration for rare earth minerals in California. Recently, the company announced assay results from its initial diamond drilling program at the El Campo Rare Element (REE) prospect, located in the Mojave region of California. The findings confirm the presence of high-grade neodymium (Nd) and praseodymium (Pr) mineralization, pivotal for technologies demanding permanent magnets such as electric vehicles and defense systems.
Located about 3.4 miles southeast of MP Materials' Mountain Pass Mine, the only active rare earth mine in the U.S., the El Campo project showcases significant mineralization that is attracting attention. The assays indicate that neodymium and praseodymium oxides account for approximately 25% of total rare earth oxides (TREO). Among the promising drill intercepts are some notable highlights:
- - A peak value of 6.03% TREO over a length of 0.7m in drill hole ECDD0002.
- - A longer interval of 7.2m @ 2.93% TREO in the same hole, which includes a more concentrated section of 3.75m @ 4.45% TREO.
- - Additional findings from drill hole ECDD0004 included 0.90m @ 1.09% TREO.
These results reinforce the strategic significance of the rare earth elements discovered, especially neodymium and praseodymium, which are essential ingredients in various advanced technologies and manufacturing processes. Ian Stockton, the non-executive technical director at Locksley Resources, emphasized the importance of these results, stating, "Diamond drilling at the El Campo prospect represents the first test of the depth extensions of known REE minerali attractions that can be traced back to the surface. The initial findings are encouraging and align well with the observations collected through surface mapping and sampling."
Furthermore, Locksley Resources reported concurrent drilling success at its Dam Antimony Mine (DAM), which intersected substantial antimony mineralization beneath historically mined areas. Notable assay results from the final two of eight completed drill holes included:
- - A peak value of 6.44% Sb over 0.3m in DADD0007.
- - An additional 0.3m @ 2.90% Sb also in DADD0007.
These findings at the DAM add another layer of promising developments for Locksley, potentially extending antimony mineralization towards the south while remaining open along the strike and at depth. Stockton expressed confidence regarding the importance of these results, stating that they confirm the presence of high-grade antimony mineralization that is expected to continue beyond the historic mining areas.
Locksley Resources’ focus on critical minerals includes ongoing initiatives to advance the Mojave Project, targeting both rare earth elements and antimony. By implementing a mine-to-market strategy for antimony, the company aims to re-establish domestic supply chains for essential materials, supported by strategic partnerships with leading research institutions and industry leaders in the U.S. With innovative processing methods, Locksley Resources is positioning itself as a key player in the field of U.S. critical materials independence. As exploration continues at El Campo and DAM, the interest in rare earths and antimony is likely to escalate, positioning Locksley at the forefront of resource development in a crucial sector.
