Antimony Resources Limited (ASX:ANT)

Antimony Resources Limited (ASX: ANT) announced that its Tecomatlán antimony processing plant in Puebla, Mexico has advanced into the integrated processing and concentrate recovery phase of its Proof-of-Concept programme, marking progress toward first bulk antimony concentrate production. Key processing circuits are now operational following commissioning and optimisation, and the plant is undergoing a controlled ramp-up focused on improving throughput, metallurgical recoveries and concentrate quality. The current campaign is targeting about 200 tonnes of previously prepared Chinantla feed material to demonstrate production of a marketable antimony concentrate, while around 40 tonnes of low-grade test material has already been processed and recycled to optimise the flotation circuit. ANT also expects to add on-site XRF analytical capability to improve monitoring before moving to higher-grade feed. The company said its immediate priorities are to establish stable processing conditions, recover first bulk concentrate, and gather operating and metallurgical data, after which it plans sampling and independent assay verification to confirm product specifications and support initial commercialisation activities, including an initial commercial sale under discussion. The announcement also reiterates ANT’s broader strategy of building an integrated North American antimony business centred on Tecomatlán, supported by Los Lirios in Mexico and its Nevada antimony assets, while noting that the current PoC campaign uses third-party Chinantla material and is not based on a JORC resource, ore reserve, production target or feasibility study.
