How EV Resources Is Unlocking High-Grade Antimony at Los Lirios

Exploration Momentum Builds at Los Lirios

EV Resources Limited (ASX – EVR) has reported significant progress in its exploration efforts at the Los Lirios Antimony Project, located in Oaxaca State, Mexico. The company’s recent fieldwork has focused on trenching, channel sampling, geological mapping, and infrastructure upgrades, all aimed at advancing the project to a drill-ready stage. This systematic approach is designed to underpin EVR’s maiden drilling program and the subsequent JORC-compliant resource estimate.

To date, nine trenches have been completed along a 5-kilometre mineralised structure, with over 30 channel samples collected from key stopes confirming the continuity of high-grade antimony mineralisation. Detailed geological mapping has identified key mineralising features, including gypsum dike-strata and brecciated monzonite dikes, which are interpreted as primary conduits for antimony mineralisation.

Infrastructure and Community Engagement

Recognising the importance of logistics in exploration success, EVR has undertaken extensive road cleaning, reconditioning, and extension works to ensure safe and efficient access to the main pits. These improvements are critical for the mobilisation of drilling rigs and equipment in the near term. Concurrently, the company continues to foster strong relationships with local communities, ensuring ongoing support for exploration and future development activities.

Strategic Importance Amid Global Supply Risks

Antimony is a critical mineral with limited global supply, predominantly controlled by China and Russia. Geopolitical tensions and export restrictions have heightened supply chain risks, prompting strategic initiatives by the U.S. and allied nations to secure independent sources. EV Resources’ Los Lirios project positions the company as a promising non-China supplier of high-grade antimony, aligning closely with U.S. Department of Defense priorities and broader critical minerals policies.

EVR Chairman Shane Menere emphasised the project’s potential, noting that the exploration work is unlocking one of the highest-grade undeveloped antimony deposits in the Americas. He highlighted the project’s role in EVR’s near-term production strategy and its significance in addressing worsening antimony scarcity globally.

Next Steps and Outlook

The company is currently finalising assay results from channel and trench samples, with progressive releases expected. Preparations for the maiden drilling program are underway, including the finalisation of drill pad locations. EVR also continues its community and environmental engagement to support necessary approvals. Looking ahead, the initial drilling results will feed into a maiden JORC resource estimate, laying the groundwork for near-term mining operations and ore supply to a nearby processing facility under development.

While the exploration progress is promising, EVR cautions that forward-looking statements are subject to risks including resource confirmation, financing, and regulatory approvals. Nonetheless, the company’s methodical advancement at Los Lirios reflects a strategic response to critical mineral supply challenges and positions EVR as a key player in the evolving antimony market.
