Locksley Resources (ASX: LKY) Jumps 15% on Antimony Supply Deal

Locksley Resources  — Antimony Supply Agreement Expands U.S. Critical Minerals Strategy

Locksley Resources (ASX: LKY) caught investors’ attention this morning with a sharp 15 percent surge after revealing a new partnership that could reshape its growth path. The company has entered a non-binding heads of agreement with EV Resources to secure future antimony supply, while also committing a 0.75 million AUD strategic investment in EVR. Antimony, though little known outside specialist circles, is a critical input in everything from electronics to flame retardants and energy storage. It is precisely these applications that make the market so strategically important and so closely tied to global supply chains.

For Locksley, the arrangement offers access to feedstock from EVR’s Los Lirios project in Peru, neatly complementing its own Mojave Desert antimony project in California. Together, these assets speak to a bigger story: the race to establish secure, non-Chinese supply of a mineral the US has labeled critical to national security. The question for investors now is whether Locksley can turn this momentum into lasting value. That is where the deeper analysis begins.

Locksley Resources Targets U.S. Critical Minerals with Mojave Project Push

Locksley Resources is an exploration company focused on critical minerals in the United States, where demand for secure supply is growing rapidly. The company is advancing work across two key assets, including the Mojave Project in California, which is prospective for both rare earth elements and antimony. By pursuing targeted exploration and development in this mineral-rich region, Locksley is positioning itself to create long-term shareholder value through the discovery and advancement of strategically important resources.

Locksley Secures Third Party Ore to Advance U.S. Antimony Processing Vision

The purpose of this agreement is to provide Locksley Resources with access to third party ore, strengthening the commercial pathway for its proprietary DeepSolve processing technology. For context, if investors are familiar with Metallium’s electrothermal approach to rare earth processing, Locksley’s technology follows a similar principle, designed to deliver more efficient outcomes.

From a strategic perspective, Locksley resources development supports U.S. domestic security of supply for antimony, a mineral considered essential in defense, semiconductors, and advanced alloys. Locksley, in partnership with Rice University, is progressing research on a green, low energy solvent process for antimony using resources from its Mojave Project in California, now complemented by third party feedstock. This alignment not only advances the company’s commercialisation strategy but also reinforces the broader vision of re-establishing U.S. based antimony processing. In doing so, Locksley is positioning itself as a potential cornerstone supplier in a market that remains heavily reliant on Chinese imports.

The investors Takeaway 

The announcement highlights Locksley’s progress as an early mover in rebuilding a domestic U.S. antimony supply chain. If the strategy succeeds, the combination of the Mojave project, third-party ore sourcing, and the company’s proprietary processing technology could create meaningful strategic value. However, investors should also recognise that the current agreement is non-binding, with no obligation on either party to complete it. In addition, execution risk remains high, as the DeepSolv™ process is still undergoing validation and continued research and development, and has not yet been commercially proven.
