Mexican gold‑silver mining activity 2026

In late July 2026, Sierra Madre Gold & Silver reported that its La Guitarra silver‑gold complex in the Temascaltepec district generated operational cash flow and announced a staged expansion of its processing plant, aiming to raise throughput to up to 1,500 t/d by late 2027 and to complete a 30 km drilling program in the East District.

A week later, Tocvan Ventures disclosed a near‑surface gold‑silver discovery at its Gran Pilar project in Sonora, with high‑grade intercepts located close to a planned pilot production facility. The same release also noted additional Mexican mining activity: Guanajuato Silver obtained permits for a surface drilling program at El Horcón in Jalisco, and Pinnacle Silver and Gold reopened historic workings at El Potrero, reporting high‑grade channel samples. These developments illustrate a period of heightened exploration success and operational scaling across multiple junior miners in Mexico.
