• Diamond drilling has commenced at the El Campo Rare Earth Element (REE) Prospect
• Maiden program comprises four initial diamond drill holes targeting sheared carbonatite-hosted REE mineralisation
• Drilling will test the depth and lateral continuity of mineralisation along 900m of strike, where previous surface sampling returned results of up to 12.1% TREO

Locksley Resources Limited (ASX: LKY, OTCQX: LKYRF, FSE: X5L) has announced the commencement of diamond drilling at the El Campo Rare Earth Element (REE) Prospect, part of its Mojave Project in California. The initial drilling program comprises four diamond drill holes and is designed to evaluate the scale, continuity, and geological characteristics of REE mineralisation identified through historical work and recent surface sampling. Previous surface sampling has returned results of up to 12.1% TREO, underscoring the potential for high-grade REE mineralisation at the project. The program aims to test the depth and lateral continuity of REE mineralisation along approximately 900 metres of strike, validate geological and structural interpretations, and obtain core samples for detailed analysis and future metallurgical testwork. The drilling is expected to take 3 weeks to complete, with first assay results delivered upon submission for analysis. El Campo is strategically located approximately 4 miles southeast of MP Materials' Mountain Pass REE Mine, one of the world's most significant rare earth operations globally. This strategic position within a well-established mineral province places El Campo as a highly prospective REE target in a Tier-1 jurisdiction, with excellent access to existing infrastructure and processing knowledge. The current drilling program at El Campo forms part of Locksley's broader strategy to advance domestic U.S. critical minerals supply, contributing to national security and supply chain resilience.

Locksley Resources is executing a mine-to-market strategy for antimony, aimed at re-establishing domestic supply chains for critical materials, underpinned by strategic downstream technology partnerships with leading U.S. research institutions and industry partners. This integrated approach combines resource development with innovative processing and separation technologies, positioning Locksley to play a key role in advancing U.S. critical minerals independence.
