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

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.

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

antimony (sb) technical

"a batch sampling program at the DAM antimony (Sb) deposit, part of the Mojave"

Antimony (Sb) is a brittle, silvery-gray metal used as an ingredient in flame retardants, lead-acid batteries, solder, and certain electronic and chemical applications; think of it as a small but essential helper that gives other materials useful properties, like making them more heat-resistant or durable. Investors watch antimony because its price and availability affect costs and profits across several industries, and supply disruptions or changes in demand can quickly influence related stocks and commodity markets.

premium concentrate technical

"including a 325kg sample and the production of a 68.1% Sb premium concentrate"

A premium concentrate is a high-quality, higher-purity version of a concentrated product—such as an oil, extract, or food ingredient—created to deliver stronger potency, cleaner composition, or better performance than standard grades. For investors it signals potential for higher pricing, stronger margins, and brand differentiation, but also may require stricter quality control, certification and supply-chain costs; think of it like espresso versus regular coffee in terms of concentration and price.

metallurgical technical

"to provide a representative range for metallurgical testwork, returning weighted"

Metallurgical describes the processes and techniques used to extract, separate, refine and test metals from ore or recycled material, including crushing, melting, chemical separation and quality assays. For investors, metallurgical performance determines how much saleable metal a project yields, how costly and risky production will be, and whether a mine or plant can meet product and environmental standards—like the recipe and kitchen that turn raw ingredients into a marketable product.

rare earth elements (rees) technical

"targeting rare earth elements (REEs) and antimony. Locksley is executing a"

Rare earth elements (REEs) are a group of 17 metallic elements used as specialized ingredients in many modern technologies — from smartphones and electric vehicles to wind turbines and defense systems. They matter to investors because their supply is limited and concentrated in a few countries, which can cause sharp price swings, create strategic risks for manufacturers, and influence the profitability and competitiveness of companies that rely on these materials.

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."

Locksley Resources (https://www.locksleyresources.com.au) is focused on critical minerals in the U.S. The company is actively advancing the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley is executing a mine-to-market strategy for antimony, aimed at reestablishing domestic supply chains for critical materials, underpinned by strategic downstream technology partnerships with leading U.S. research institutions and industry partners. This targeted approach, combined with resource development with innovative processing and separation technologies, positions Locksley to play a role in advancing U.S. critical materials independence.
