Locksley's Mojave Antimony Sampling Yields High-Grade Results
Event summary
- Locksley Resources announced high-grade antimony results from a batch sampling program at the DAM deposit within its Mojave Project in California.
- The program targeted mineralized vein material, with Batch 1 returning a weighted average of 25.7% antimony (Sb).
- Subsequent batches, designed for metallurgical testwork, yielded 21.3% and 11.4% Sb averages, with a combined total of 18.7% Sb across 287kg of samples.
- Locksley previously produced a 68.1% antimony concentrate in late 2025, following a 325kg sample.
The big picture
Locksley’s focus on antimony aligns with the broader push for critical mineral independence within the U.S., particularly driven by national security concerns and the energy transition. The company’s strategy of targeting primary antimony sources, rather than byproduct recovery, positions it to potentially capture a significant share of a market currently reliant on foreign imports. The results from the batch sampling program represent a positive step, but the company’s success will depend on translating these findings into a commercially viable mine.
What we're watching
- Resource Definition
- The consistency of high-grade antimony across multiple batches will be crucial in defining the extent and economic viability of the DAM deposit, and whether the initial results can be replicated across the broader Mojave Project.
- Downstream Partnerships
- The success of Locksley’s ‘mine-to-market’ strategy hinges on the ability to secure and scale downstream technology partnerships, particularly given the stated need for antimony in the defense and energy sectors.
- Market Dynamics
- The U.S. government’s stated demand for domestically sourced antimony will influence pricing and offtake agreements, and Locksley’s ability to capitalize on this demand will be a key indicator of long-term success.
