• Excellent high grade final flotation concentrate of 68.1% achieved
• Concentrate is 95% of technical maximum stibnite grade with minimal impurities
• Concentrate grade significantly exceeds marketable sales requirement of minimum 55%

Locksley Resources Ltd has provided an update on the rapidly advancing metallurgical test work program being conducted on surface samples collected from the Desert Antimony Mine (DAM) Prospect. Second stage cleaner flotation testwork has delivered a high-grade concentrate containing up to 68.1% antimony, substantiating that the Mojave Project has the potential to deliver feedstock superior to current market supply streams and prospects. Grades at this level of purity advance the pathway to a high quality 100% Made in America antimony product aligned with US government priorities for a fully integrated antimony supply chain for defence and industrial base resilience particularly munitions, semiconductors and energy systems. The updated metallurgical program has produced a concentrate grade far in excess of the minimum marketable grade of >55% Sb, approaching the theoretical maximum stibnite grade of 71.68% Sb. Antimony recovery in the cleaner flotation testwork achieved 60.5%, with the balance of 21.4% reporting to the cleaner flotation tail which will undergo recirculation in a closed circuit with further regrinding and re-flotation expected to recover most of the remaining antimony metal. Further testwork and optimisation of the flotation process will be undertaken to improve the recovery to the cleaner concentrate with overall total recoveries expected to exceed 80% as demonstrated by the rougher flotation testwork.
