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.
