Six (6) rock chip samples grading >0.5% Sb
Highlights
- Locksley’s Exploration team has been mobilised to follow-up on the high-grade Desert Antimony Mine results in the North Block at the Mojave Project
- The Desert Antimony Mine returned rock chip samples as high as 11.2% & 8.33% Antimony (Sb)
- High-grade antimony is represented by historic underground mine workings on quartz-stibnite (Sb2S3) veins
- Mindat.org outlines historic production ranged from 100 to 1,000 tons with grades ranging from 15 to 20% Sb at the Desert Antimony Mine
- Antimony is listed as a critical mineral by the U.S. Department of Interior as it is used in a wide variety of military, energy, industrial and consumer applications
- USA has no domestic primary mined source of Antimony and China has announced it will cut off the global supply of antimony from 15 September 2024
- Additionally, a sample to the south-east of the Desert Antimony Mine assayed at 4.12% Cu
EL CAMPO PROSPECT – Rock-chip Geochemistry
Highlights
- The Mojave Project consists of three areas: The North Block comprised of 184 claims totaling 14.9km², North East Block comprised of 71 claims totaling 5.7km², South Block comprising of 37 claims totaling 3.5km², and the El Campo Prospect comprising of 5 claims totaling 0.34km²;
- Five (5) of the 25 rock-chip samples collected at the El Campo Prospect returned high grade TREO results of 3.74% to 9.49% within a 6-metre-wide mineralized zone;
- The Mojave North Block lies 1.4 km to the north-east of the Mountain Pass Open Pit Mine, the largest rare-earth element (REE) mine in the U.S;
- The Mojave Project has potential to host numerous REE deposits. Rare earth elements (REE) are indispensable for the functioning of modern society, powering technological innovations and enabling advancements in renewable energy, electronics, and defense systems;
- The Mojave Project is located on California’s south-eastern border with Nevada, USA;
The Mojave Project is positioned next to one of the highest-grade REE mines in the world and multiple significant carbonatite REE veins have been identified. 13 targets, 19 interpreted geophysical features and 4 REE mineral prospects have been identified for field review.
The El Campo Prospect has produced high grade samples with five of the twenty-five rock-chip samples collected, returning TREO results with assays up to 9.49%. These samples were collected from outcrops of syenite, shonkinite and carbonatite comprising a 6-meter-wide mineralised zone.
Occurrences of dykes of mid-Proterozoic intrusive rocks including syenite, shonkinite and carbonatite have been documented in the El Campo claim blocks and are interpreted to also be found in the North and South blocks. The Proterozoic carbonatite terrane at Mountain Pass hosts the largest resource of REE’s in North America.
The close proximity of the El Campo Prospect to the Mountain Pass Mine and high-grade rockchip samples provides strong potential for further significant REE discoveries within the exploration package
