Locksley Resources Ceases Mojave Project Exploration Amid Antimony Price Collapse
Locksley Resources (ASX: LKY) has reached a pivotal milestone in its development of the Mojave Antimony and Rare Earths Project, formally submitting drilling permits to the Bureau of Land Management (BLM) for its high-grade Desert Antimony Mine.
The timing couldn't be more advantageous, with the project poised to benefit from President Trump's March 2025 Executive Order mandating fast-tracked approvals for critical mineral developments to secure America's supply chains.
Located a mere 1.4 kilometers from Mountain Pass Mine—the only producing rare earth mine in the United States—Locksley's Mojave Project combines exceptional antimony grades with significant rare earth potential in what is rapidly becoming America's most strategic minerals district.
Surface sampling at the Desert Antimony Mine has returned extraordinary results that establish the project's world-class potential:
This high-grade antimony system is particularly significant as antimony is classified as a critical mineral by the U.S. Department of Interior, with limited domestic supply options. Recent discoveries by Warriedar Resources at their Ricciardo gold deposit have also highlighted the growing importance of antimony in the resources sector.
| Mineral | Peak Grade | Strategic Significance |
|---|---|---|
| Antimony | 46% | Critical for defence applications, batteries, flame retardants |
| Silver | 1,022 g/t | Precious metal byproduct enhancing project economics |
| Rare Earths (El Campo) | 12.1% TREO | Essential for EVs, wind turbines, electronics |
| NdPr (El Campo) | 3.19% | High-value rare earth elements for permanent magnets |
While the antimony results alone would make the Locksley Resources Mojave Project development noteworthy, Locksley's holdings also demonstrate exceptional rare earth element (REE) potential:
The proximity to Mountain Pass Mine is critically important—this neighbouring operation represents the only domestic source of rare earth elements in the United States, giving the Locksley Resources Mojave Project development enhanced strategic significance in a nation seeking to reduce dependence on Chinese critical minerals. In the rare earth space, companies like Prospech with their Finnish REE project are also making significant strides with high-grade discoveries.
Nathan Lude, Chairman of Locksley Resources, commented on the strategic timing of the company's permitting application:
"Our formal permit submission coincides perfectly with the U.S. government's renewed focus on domestic critical mineral development. The BLM has already indicated they'll expedite the Environmental Assessment requirements that typically delay projects by a year or more. With the March 2025 Executive Order specifically targeting minerals like antimony and rare earths, we anticipate a streamlined approval process."
The company is particularly encouraged by recent developments at Dateline Resources' Colosseum Project, located approximately 10km north of Mountain Pass. This project received public endorsement from the U.S. Department of Interior and was highlighted by President Trump as America's potential "second rare earth mine."
Antimony is one of the least recognised yet most strategic metals in the U.S. critical minerals list. It serves essential functions in:
The United States currently has no domestic antimony production, relying entirely on imports—primarily from China and Russia. This supply vulnerability has been identified as a national security concern, with the Defense Logistics Agency actively seeking new sources. Furthermore, Trigg Minerals' recent acquisition of antimony-gold projects demonstrates the growing industry interest in securing this critical mineral.
With grades reaching 46% Sb, Locksley's Desert Antimony Mine represents one of the highest-grade undeveloped antimony resources in North America. For context, operating antimony mines typically process ore at 1-5% Sb, highlighting the exceptional nature of the Desert Antimony discovery.
The company has outlined a focused strategy to advance the Mojave Project:
The Locksley Resources Mojave Project development will benefit from the federal mandate to accelerate critical mineral projects through:
Locksley Resources presents a compelling investment opportunity at the intersection of multiple high-value catalysts:
Strategic Critical Minerals Focus – The company's antimony and rare earth elements are at the forefront of U.S. national security and industrial policy priorities.
Exceptional Grades – Surface sampling has confirmed world-class antimony concentrations (up to 46%) and significant rare earth values (up to 12.1% TREO), suggesting strong economic potential.
Prime Location – Being situated just 1.4km from America's only producing rare earths mine adds immense strategic value and development potential to the Locksley Resources Mojave Project development.
Policy Tailwinds – Recent executive orders specifically designed to accelerate projects like Mojave create a favourable regulatory environment.
Two-Pronged Opportunity – The dual focus on antimony and rare earths provides multiple pathways to value creation and risk diversification.
With upcoming catalysts including drill permit approvals, potential federal project designation, and further exploration results, Locksley Resources offers investors direct exposure to America's critical mineral renaissance at precisely the right moment. The strategy mirrors success seen in other mineral sectors, where companies like KGL Resources at their Jervois project and Hammer Metals with their Queensland discoveries have created significant value through strategic mineral exploration.
The company's position in both antimony and rare earths markets—both facing severe supply constraints and growing demand—provides a unique opportunity to capitalise on two of the most strategically important mineral segments in today's geopolitical landscape.
