The silver and gold deposits of the world-class Palmarejo district are typical intermediate sulfidation-style epithermal precious metal occurrences hosted in Cretaceous- to Tertiary-age volcanic and intrusive rocks, of the Lower Volcanic Complex (LVC), and now host one of the newest and largest silver and gold producers in Mexico. The district, along with a surface and underground mine and new 6,000 tpd ore processing facility, is owned and operated by Coeur dâ∈™Alene Mines Corporation through its wholly owned subsidiary, Coeur Mexicana S.A. de C.V. Palmarejo is located in the southwest portion of the State of Chihuahua in the Sierra Madre Occidental (SMO) epithermal belt (Fig. 1).
