Pan American-Dolores Mine
Dolores is an open pit silver-gold mine located in Chihuahua, Mexico, and was acquired in 2012 as part of Pan American’s acquisition of Minefinders Corporation Ltd.
Silver and gold mineralization is present as structurally controlled, low to medium sulphidation epithermal veins, silica stock works, breccias, and replacements. Mining at Dolores is currently by standard open pit methods using shovels, loaders, and haul trucks. The mine currently uses conventional cyanide heap leaching technology to produce gold and silver doré.
