EV Resources (ASX: EVR) has secured its first five-year binding ore supply agreement for the Tecomatlán plant in Mexico, advancing the refurbished and upgraded facility towards proof-of-concept production. The aim is to establish the processing of regional antimony ore through Tecomatlán and provide operational and commercial data to support a development strategy. First Binding AgreementExecutive chair Shane Menere confirmed it was the first regional feedstock MoU to be converted into a binding agreement under the company’s hub processing strategy. “This is an important milestone as we are progressively bringing together every component required for the Tecomatlán proof-of-concept campaign—the plant, the processing flowsheet, tested high-grade ore and now our first binding long-term commercial supply relationship,” he said. Alongside its broader third-party regional supply strategy, EV continues to work towards a future proprietary source of antimony supply at its 70%-owned Los Lirios project.
