The Cosalá mining district is located in the east-central portion of the state of Sinaloa, Mexico along the western edge of the Sierra Madre Occidental, an extensive tertiary volcanic province covering approximately 800,000 km2. It is accessible from the town of Cosalá via rural paved and dirt roads. All primary access roads can accommodate standard highway vehicles. Mineralization in the Cosalá district is related to granodioritic or granitic intrusions emplaced between 140 and 45 million years ago into Cretaceous sedimentary rocks that overlie older basement terranes.
In 2015, production from the Cosalá Operations totaled 1.16 million silver ounces and 2.40 million silver equivalent ounces at a cash cost of $10.80 per ounce and an all-in sustaining cost of $14.89 per ounce.
