Real de Catorce Mining Convention Q3 2026: the silver, zinc, lead and copper appointment of the Sierra Madre Oriental in San Luis Potosí, July through September
July, August and September are the quarter when the San Luis Potosí mining industry — Real de Catorce, Cerro de San Pedro, Charcas, Villa de la Paz — calibrates its procurement calendar with the OEM suppliers, maintenance service providers, regional manufacturing shops and the IMMEX operations based in Matehuala and the Altiplano. The Mining Convention is the day those suppliers sit down with the mine technical coordination, with procurement and with the IMMEX operations still receiving parts from the mining corridor. We produce the exhibitor merch with consolidated delivery to the host venue in Real de Catorce and CFDI 4.0 with the Foreign Trade Complement when the supplier is IMMEX.
