Locksley To Expand Exploration of Rare Earths Potential in Mojave North Block

• Structural and geological field mapping campaign expected to commence late this month to define high priority rare earth elements (REE) and antimony target areas.
• Four priority areas to be mapped with two focusing on REE potential within the North Block of the Mojave Project and two targeting strike extensions from mineralization identified at the Desert Antimony Prospect.
• Planning and contractor engagement underway for focused magnetic, radiometric and gravity surveys to provide additional high-resolution data sets for target refinement and prioritization.
• North Block offers significant potential for further polymetallic discoveries across its underexplored 20 sq km, expanding the critical minerals footprint of the Mojave Project.
• Technical team advancing high priority targets to build on established REE potential at El Campo.

SAN BERNARDINO, Calif., Aug. 13, 2025 /PRNewswire/ -- Locksley Resources Limited (ASX: LKY; OTCQB: LKYRF) announced it will commence an expanded geological and structural mapping program within the North Block of the Mojave Project in California. The field program, expected to commence later this month, will focus on expanding knowledge gained from the recent structural mapping program completed at the Desert Antimony Prospect. Additionally, it will include regional mapping across prospective areas within the North Block claims with potential for REE mineralization.

These new mapping target areas complement the established prospect at El Campo, which has high grade rock chip results of up to 12.1% TREO and Nd/Pr up to 3.19%. "The program is set to expand REE potential into the North Block, which lies immediately adjacent to MP Materials' Mountain Pass Mine, the only rare earths mine currently operating in the U.S.," said Nathan Lude, chairman of Locksley Resources. He added that the recent decision by both the U.S. Department of Defense and Apple to make strategic investments in MP Materials highlight the recognition by government and industry of the importance of and need for critical minerals located within the U.S.
