Locksley Resources' Underground Mapping Reveals Major New Target Boosting High-Grade Antimony Potential at its Mojave Project Desert Antimony Mine

Locksley Resources (OTCQX: LKYRF / ADR: LKYLY) reported that underground mapping at the Desert Antimony Mine within its Mojave Project identified a new exploration corridor, the Beefeater Shear, mapped at widths of 10–15 meters.

Rhea-AI Summary

Locksley Resources (OTCQX: LKYRF / ADR: LKYLY) reported that underground mapping at the Desert Antimony Mine within its Mojave Project identified a new exploration corridor, the Beefeater Shear, mapped at widths of 10–15 meters. The Stage III review combined high-resolution underground mapping and regional structural analysis.

Management said the Beefeater Shear shares structural timing with the DAM vein system, that radiometric targets were validated, and that targeted sampling and drilling will follow to confirm mineralization and economic potential.

Positive

• Identification of the Beefeater Shear mapped at 10–15 meters width

4 terms

shear zone technical

"the Beefeater Shear, is a shear zone corridor mapped at widths"

A shear zone is a band of rock that has been intensely deformed and broken by sideways motion, producing fractures, displaced layers and altered material over a measurable width. For investors in mining and exploration, shear zones matter because they often channel mineral-bearing fluids or concentrate metals, so they can indicate where ore is likely to be found, affect how much resource can be recovered and influence drilling strategy, costs and project risk.

radiometric technical

"validation of project-wide radiometric targets, pave the way for targeted"

Radiometric describes tools or methods that detect and measure radiation — from visible light and heat to X-rays and gamma rays — and turn those signals into numerical readings. Investors care because radiometric accuracy and reliability determine product performance, safety, regulatory approval and market demand across medical imaging, environmental monitoring, security and remote sensing — like how a thermometer’s precision affects trust in a weather report.

assays technical

"We look forward to receiving assays from the various surface and underground"

Assays are laboratory tests that detect or measure a specific substance, molecule, or biological activity—for example whether a drug reaches its target, how much of a chemical is present, or whether a diagnostic marker exists. Think of them like quality-control checks or sensors that tell you if an ingredient and its amount meet a standard. For investors, assay results drive clinical decisions, regulatory approval, manufacturing quality and timelines, all of which affect a company’s value and risk.

rare earth elements technical

"The company is actively advancing the Mojave Project in California, targeting rare earth elements (REEs)"

Rare earth elements are a set of 17 chemical metals used to make powerful magnets, batteries, catalysts and many tiny components inside electronics, renewable energy equipment and defense systems. They matter to investors because they are essential inputs for fast‑growing industries, and limited or concentrated supply can drive prices, create production bottlenecks or shift competitive advantage — like a factory running short of a specialized ingredient that halts output and affects profits.

SAN BERNARDINO, Calif., Feb. 10, 2026 /PRNewswire/ -- Locksley Resources Limited (ASX: LKY; OTCQX: LKYRF/ADR: LKYLY) announced a major new target zone revealed by underground mapping at its Desert Antimony Mine (DAM), part of the company's Mojave Project.

This notable finding, the Beefeater Shear, is a shear zone corridor mapped at widths of up to 10-15 meters and a result of a comprehensive Stage III technical review focusing on the Northern Block. This included high-resolution underground mapping at the DAM and regional structural analysis.

"Locksley's geology team considers Beefeater to share the same structural timing and kinematic history as the DAM mineralized vein system to the West," said Kerrie Matthews, Managing Director and CEO of Locksley. She added that these insights along with the validation of project-wide radiometric targets, pave the way for targeted sampling and drilling to confirm mineralization and economic potential. "This allows us to focus on extensions with greater certainty," she said, noting that by mapping the underground workings at DAM the company has essentially "unlocked" the geometry of the system.

"We now see exactly how high-grade, mineralized blocks have been created by later structural events," she affirmed adding the identification of the 10-15 meter Beefeater Shear provides Locksley with a new exploration target that can increase the exploration pipeline of critical mineral projects on the Mojave claims. "We look forward to receiving assays from the various surface and underground sampling," she said.

Locksley Resources (https://www.locksleyresourcescom.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.
