Locksley Resources Limited has delivered substantial advancements at its Mojave Project in California during the September 2025 quarter. The company has made significant progress on multiple fronts, including advancing strategic partnerships, strengthening its downstream positioning, and achieving key regulatory milestones. Locksley has partnered with Rice University to develop the DeepSolv™ clean-tech extraction technology, which aims to create a scalable, low-carbon pathway for antimony refining. The company has also engaged with the U.S. Department of War and EXIM Bank to access non-dilutive funding and align the Mojave Project with critical minerals and defense initiatives. Locksley has expanded its strategic land position, staking an additional 249 claims, and has refined high-priority drill targets through fieldwork. The company has also bolstered its board and executive team with key appointments. Locksley completed a A$5.3 million oversubscribed placement, ensuring it is fully funded for the planned exploration programs. Subsequent to the quarter, the company successfully cast the first 100% American-made antimony metal ingot in decades, demonstrating the technical feasibility of restoring domestic antimony refinement.

Locksley Resources is targeting the production of antimony and rare earth elements from its Mojave Project in California. The company has not provided any specific financial guidance for the upcoming financial/calendar year.

Locksley Resources is focused on advancing its mine-to-market strategy for antimony, aimed at re-establishing domestic supply chains for critical materials. The company is leveraging strategic downstream technology partnerships to develop innovative processing and separation technologies, positioning it to play a key role in advancing U.S. critical minerals independence.
