Select a location on the map to discover more about our operations.
Our core operations are in Mexico, a country with significant geological resources, strong potential for continued growth, a skilled workforce and solid infrastructure, with a mining history extending more than 500 years.
Fresnillo has seven operating mines; Fresnillo, Saucito, Ciénega (including Las Casas Rosario & Cluster Cebollitas), Herradura, Soledad-Dipolos1, Noche Buena and San Julián (Veins and Disseminated Ore Body); two development projects - the Pyrites Plant at Fresnillo and Juanicipio, both of which have been completed and awaiting tie-ins of plants to national electricity grid, and three advanced exploration projects – Orisyvo, Rodeo and Guanajuato, as well as a number of other long term exploration prospects.
We have a strong and long tradition of mining, a proven track record of mine development, reserve replacement, and production costs in the lowest quartile of the cost curve for silver, with mining concessions and exploration projects in Mexico, Peru and Chile.
Our goal is to maintain the Group's position as the world's largest primary silver company and Mexico's largest gold producer.
