EV Resources (ASX: EVR) has purchased 200 dry tonnes of high-grade antimony ore from the Chinantla mine in Mexico to feed a proof-of-concept (PoC) processing campaign at the Tecomatlán plant. The ore has been mined and stored approximately eight kilometres from the Tecomatlán gates, with haulage scheduled to commence within the fortnight. Executive chair Shane Menere said the PoC campaign would test the company’s regional hub model from third-party ore purchasing through to concentrate production. “This is the point where the strategy moves from assembling the pieces to demonstrating the complete commercial cycle—buying regional ore, processing it through our own plant, and producing a marketable antimony concentrate,” he said. EV Resources is building an integrated North American antimony value chain, combining regional ore supply and processing at Tecomatlán with potential future proprietary feed from its Los Lirios antimony project, and direct US exposure through its Nevada assets.
