Pan American-Morococha Mine

Pan American entered into an agreement in 2004 to purchase the mine and currently has a total ownership interest of approximately 92.3%. Silver, zinc, lead, and copper mineralization is present as a complex system of epithermal veins, mantos, and limestone replacements.

Underground mining operations at Morococha consist primarily of conventional and mechanized overhand cut and fill, long hole open stoping, and stope development. Morococha operates an 803,000 tonne per year capacity mill, known as the Amistad mill, using froth induced selective flotation technology to produce silver in zinc, lead, and copper concentrates.
