EV Resources (ASX:EVR) has secured 200 dry tonnes of ‘high-grade’ antimony ore, completing the inputs required for its first proof-of-concept processing campaign at the Tecomatlán plant in Mexico.
The company’s Mexican subsidiary, Stibcorp, will purchase the stockpiled ore from Lucero Grupo Minero de Puebla for an estimated MXN$3.2 million (around $264,600), plus value-added tax.
Laboratory analysis returned grades of 13–16% antimony. Previous flotation test work on Chinantla material achieved 81.1% antimony recovery and produced a concentrate grading 42.4% antimony, which EVR says could be upgraded to 62.9%.
The ore is stockpiled about 8km from Tecomatlán, with haulage scheduled to begin within two weeks.
Executive Chairman Shane Menere says the plant’s crushing, grinding, and flotation circuits have been individually commissioned and are ready for feed.
“This purchase provides characterised, high-grade ore only 8km from the plant, and gives us what we need to commence the first Tecomatlán processing campaign,” Menere says.
“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.”
EVR notes it will pay MXN$400,000 on signing, MXN$1.2 million when operations begin, and MXN$1.6 million after processing is completed. The final consideration will be reconciled against the dry tonnes and average antimony grade processed.
The parcel is the first purchase under a binding five-year ore supply agreement announced on 6 August 2026.
EVR says it plans to use the campaign to generate plant throughput, recovery, concentrate grade, and operating cost data while progressing discussions with potential buyers and strategic partners.
The ore forms part of a stockpile containing about 500 tonnes. EVR may purchase the remaining 300 tonnes once the initial parcel has been sold to an end buyer, but is not obliged to acquire the material.
