EV Resources Advances Mexico Antimony Hub Toward Near-Term Production

Why It Matters

The advances bring EV Resources closer to a maiden JORC resource estimate in 2026 and position it to become the first North American antimony producer, a critical metal for electric‑vehicle batteries and flame‑retardants. Early production could capture premium pricing and support supply‑chain diversification.

Key Takeaways

• 11 diamond holes drilled at Lirios 1, assays pending.
• New “San Miguel” vein shows up to 3.05% antimony by XRF.
• 13‑km CSAMT survey targets Lirios Fault Zone for mineralisation fingerprint.
• Tecomatlán plant refurbishment on track for H2 2026 start.
• Near‑term plan processes artisanal ore, reducing capital spend.

Pulse Analysis

Antimony, a key component in flame‑retardant polymers and emerging electric‑vehicle battery chemistries, has faced tight supply and price volatility as traditional producers in China grapple with environmental constraints. EV Resources’ Mexico hub offers a rare opportunity to diversify the global supply chain, leveraging the country’s stable mining jurisdiction and proximity to North American end‑users. By integrating exploration, processing and a low‑capital production model, the company aims to capture a growing market niche while mitigating the geopolitical risks that have plagued the sector.

The latest field campaign underscores the project’s technical momentum. Eleven diamond drill holes at the Lirios 1 prospect have been logged, and a previously unknown shallow vein—dubbed “San Miguel”—exhibited handheld XRF readings as high as 3.05% antimony, confirming surface‑grade mineralisation. Complementary geophysical work, including a 13‑kilometre CSAMT line and ground‑magnetics survey across the Lirios Fault Zone, is being used to develop a fingerprint that can accelerate drill targeting across the largely unexplored 90% of the property. These data feed directly into EV Resources’ goal of delivering a maiden JORC‑compliant resource estimate by Q3 2026.

Equally critical is the refurbishment of the Tecomatlán processing plant, which will host a gravity‑based concentrator capable of achieving over 90% antimony recovery. The five‑week grinding‑circuit upgrade keeps the plant on schedule for H2 2026 commissioning, allowing the company to process ore from local artisanal miners while the Los Lirios deposit ramps up. This low‑capex pathway reduces upfront risk and positions EV Resources to meet near‑term demand, with upcoming catalysts including drill‑hole assay releases, geophysical results and potential off‑take agreements.
