Sierra Madre Gold and Silver Ltd. is a precious metals producer and exploration company focused primarily on silver and gold assets in Mexico. The company’s flagship operation is the La Guitarra mine, located in the historic Temascaltepec mining district within Mexico’s prolific Silver Belt. This fully permitted underground mine complex includes an on-site 500 tonne-per-day processing mill, and commenced commercial production under Sierra Madre’s stewardship in January 2025 following previous operations through 2018. La Guitarra features extensive exploration potential with over 100 known epithermal veins and several past-producing zones spread across a 39,714-hectare property, emphasizing district-scale growth opportunities.

Sierra Madre also operates the Tepic project in Nayarit, which hosts low-sulfidation epithermal gold and silver mineralization and is recognized for its potential to expand historic resources both in grade and tonnage. Supported by an experienced management team with a track record in advancing significant gold and silver assets, the company plays a vital role in supplying precious metals for both investment and industrial applications, positioning itself as an emerging contributor in Mexico’s mining sector.
