Locksley Announces High-Grade Antimony Results from Batch Sampling Program at its Mojave Project

Rhea-AI Summary

Locksley Resources (OTCQX: LKYLY) reported high-grade antimony results from a batch sampling program at the DAM deposit, Mojave Project, California on Feb 3, 2026.

Three batches (total 287kg) returned weighted averages of 25.7% Sb, 21.3% Sb, and 11.4% Sb. Prior late-2025 work included a 325kg sample and a 68.1% Sb premium concentrate. Locksley says it is pursuing a mine-to-market strategy with downstream partnerships to rebuild U.S. antimony supply chains.

Positive

• Batch 1 weighted average 25.7% Sb
• Batch 2 weighted average 21.3% Sb
• Produced a 68.1% Sb premium concentrate in late 2025
• Total sampled mass 287kg across three batches

Negative

• Batch 3 weighted average only 11.4% Sb, showing grade variability
• Sample dataset size limited to 287kg, constraining representativeness

SAN BERNARDINO, Calif., Feb. 3, 2026 /PRNewswire/ -- Locksley Resources Limited (ASX: LKY; OTCQX: LKYRF; OTCQX ADR: LKYLY) announced that a batch sampling program at the DAM antimony (Sb) deposit, part of the Mojave Project in California,  returned high grade antimony results.

The batch sampling program, which was designed to further evaluate the high-grade antimony mineralization at DAM following technical milestones achieved in late 2025, including a 325kg sample and the production of a 68.1% Sb premium concentrate, targeted specific mineralized vein material within the historical workings.

"The results exceeded our expectations," said Kerrie Matthews, Locksley Managing Director and CEO. She added, "There were three batches sampled. Batch 1 returned a weighted average of 25.7% while Batches 2 and 3 sampling focused on both high-grade and low-grade material to provide a representative range for metallurgical testwork, returning weighted averages of 21.3% Sb and 11.4% Sb, respectively. The total weighted average grade of all samples combined (287kg) was 18.7% Sb."

Matthews noted that Locksley's consistent return of double-digit percentages at more than 25% underscores the potential for the Desert Antimony Mine. "We aren't just looking at byproduct antimony; we are looking at a rich, primary source of a metal that the U.S. Department of Defense and the energy sector desperately need."
