Locksley Announces High-Grade Antimony Assays at Desert Antimony Mine Confirm Surface Continuity

Rhea-AI Summary

Locksley Resources (OTCQX: LKYRF / ADR: LKYLY) reported high-grade antimony assays from surface grab sampling at the Desert Antimony Mine on March 3, 2026, with a peak value of 16.90% Sb.

Surface earthworks identified extensions of stibnite-bearing veins along strike and above historical underground workings; maiden diamond drilling is underway to refine geometry and evaluate resource potential.

Positive

• Peak assay of 16.90% antimony (Sb)
• Surface continuity of high-grade stibnite along strike confirmed
• Maiden diamond drilling currently underway to refine geometry

Negative

• Grab samples are selective and may not represent bulk grade

SAN BERNARDINO, Calif., March 3, 2026 /PRNewswire/ -- Locksley Resources Limited (ASX: LKY; OTCQX: LKYRF/ADR: LKYLY announced high-grade antimony (Sb) assays received from surface exposure grab sampling, with a peak value of 16.90% Sb confirm continuity of high-grade stibnite mineralization along strike and above the historical undergro8und workings at the company's Desert Antimony Mine located within the Company's Mojave Project in California.

These samples were collected from earthworks conducted during preparation for the maiden drilling program currently underway. The work identified extensions of stibnite-bearing mineralized veins at surface, further validating the system's high-grade continuity and strike potential.
