Sierra Madre: La Guitarra Turns the Corner as Expansion Accelerates

Mining Stock Daily · Sep 25, 2026 · 15m

Sierra Madre Gold and Silver CEO Alex Langer joins Mining Stock Daily from Beaver Creek to discuss the continued ramp-up of the La Guitarra silver-gold mine in Mexico. Langer outlines the move toward 750–800 tonnes per day, plans to ultimately expand toward 1,200–1,500 tonnes per day, and a new 30,000-metre drill program designed to test dozens of vein systems across the property. The conversation also covers the newly acquired Del Toro project, where Sierra Madre is evaluating both a potential production restart and a much larger exploration opportunity.
