How EV Resources Is Fast-Tracking a Critical Antimony Project in Mexico

Exploration Momentum at Los Lirios

EV Resources Limited (ASX – EVR) has provided a compelling update on its Los Lirios Antimony Project in Oaxaca, Mexico, highlighting a swift and methodical exploration campaign that is rapidly unlocking the project's potential. With over 3.5 kilometres of mineralised strike now mapped, the company is targeting a large-scale, high-grade antimony deposit that could become a critical supply source in a market under significant strain.

The recent exploration activities have been extensive – 135 channel samples collected to date with approximately 80 more underway, alongside 20 trenches averaging 7 metres in length that confirm the structural continuity of mineralisation across multiple zones. Geological mapping has covered over 20,000 square metres, including a new discovery zone named El Hormiguero, revealing brecciated dikes and structural intersections consistent with high-grade antimony sulphides and oxides.

Infrastructure and Strategic Positioning

Supporting this exploration surge, EV Resources has developed more than 5.5 kilometres of new and rehabilitated roads, ensuring reliable access for field teams and the imminent drilling rigs. This infrastructure upgrade is crucial as the company prepares to commence its maiden drilling program, planned for late October or November, consisting of 10 holes totaling 2,000 metres designed to test mineralised structures to depths of approximately 120 metres.

Beyond antimony, the project exhibits promising precious metals potential, with gold and silver mineralisation observed in quartz and sulphide zones. This dual commodity opportunity could enhance the project's economics and appeal to investors seeking diversified critical mineral exposure.

Market Context and Future Outlook

Los Lirios arrives at a pivotal moment for antimony, a metal critical to various industrial and defence applications. Global supply is heavily concentrated, with China and Russia controlling over 80% of production. The U.S. Department of Defense has recently elevated antimony to the top of its critical minerals list, underscoring the urgency for new, reliable sources outside these dominant producers.

EV Resources Chairman Shane Menere emphasised the project's significance, noting the exceptional pace of exploration and the strategic timing amid historic antimony scarcity. The company is positioning Los Lirios as one of the few high-grade, large-scale antimony projects accessible to U.S. strategic buyers, potentially filling a critical supply gap.

As assay results from channel and trench samples are awaited and environmental approvals progress, the market will be watching closely. The upcoming drilling program and subsequent JORC resource estimate will be pivotal in confirming the project's scale and economic viability.
