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.

These developments illustrate a period of heightened exploration success and operational scaling across multiple junior miners in Mexico. ## Timeline ### 2026-08-04: Tocvan Ventures reports major gold‑silver discovery in Sonora, Mexico Tocvan Ventures discovered a 215‑m gold‑silver zone in Sonora, Mexico; Galantas got Chilean approvals to restart Andacollo; Guanajuato Silver received drilling permits for El Horcón; Pinnacle Silver reopened El 10 sources. https://clstr.news/cluster/mexican-silver-exploration-projects-advance-with-new-drilling-approvals ### 2026-07-24: Sierra Madre Gold reports cash flow and expansion plans at Mexico's La Guitarra mine Sierra Madre Gold reports $10.1 m revenue, $2.8 m EBITDA and $3.5 m cash flow in Q1 2026, outlines a 30 km drilling program and plans to boost La Guitarra plant capacity to up to 1,500 t/d by 2027. 3 sources. https://clstr.news/cluster/sierra-madre-gold-reports-cash-flow-and-expansion-plans-at-mexicos-la-guitarra-mine --- Cite as: Mexican gold‑silver mining activity 2026.
