EV Resources Acquires 70% Stake in Mexican Antimony Mine to Boost Critical Mineral Supply

Los Lirios Project Strengthens Strategic Positioning in the Americas

EV Resources (ASX: EVR) has finalized its acquisition of a 70% stake in the Los Lirios antimony mine in Mexico, marking a major step in the company’s strategy to build a critical minerals portfolio aligned with U.S. and allied strategic interests. The deal was completed through the creation of a wholly owned Mexican subsidiary, S9bcorp, which executed a promissory agreement for the assignment of mining rights.

The Los Lirios project spans 1,552 hectares across three mining concessions and includes historic open pits and underground workings. Though the site has a history of high-grade direct shipping ore (DSO) production, it has never housed on-site processing facilities—an opportunity EVR aims to leverage as part of its downstream ambitions.

Joint Venture Structure and Pilot Plant Plans Underway

Ownership will be held through a new joint venture company, Exploraciones Mineras los Lirios, with EVR holding 70% via S9bcorp and the original owners retaining 30% equity. EVR will manage project development and capital costs until the mine achieves a daily output of 300 tonnes. The company will also pay outstanding licensing fees and hold power of attorney over the concessions.

EVR is evaluating gravity recovery-based pilot processing and is in talks with owners of permitted plant sites in Mexico. This method has shown promising results for antimony recovery in the region. The company recently collected 30 kg of ore samples for mineralogical and recovery testwork, with results expected soon.

Antimony Emerges as a Priority for Western Governments

Antimony is classified as a critical mineral by the U.S. government, given its vital role in energy storage, military-grade alloys, flame retardants, and semiconductors. With China dominating global supply and processing, Western nations are looking to Mexico and other nearby jurisdictions as secure, alternative sources.

Los Lirios positions EVR at the forefront of this trend, offering early-stage access to a resource with strategic relevance for North American supply chains. EVR also confirmed its intent to align project development with local communities and regional economic priorities, a move designed to strengthen its social license to operate.

ScrapInsight Editorial Commentary

EV Resources’ entry into Mexico’s antimony sector marks a timely move as Western nations seek to de-risk critical mineral supply chains. With upstream access secured, EVR must now focus on downstream integration and scalable processing solutions. If successful, Los Lirios could serve as a template for strategic mineral development in the Americas.
