Pan American-La Colorado
La Colorada is an underground polymetallic silver mine located in Zacatecas, Mexico, and was acquired by Pan American in 1998. Silver, gold, zinc, and lead mineralization is present as epithermal veins, breccia pipes, mantos, and lime stone replacements in three main zones known as Candelaria, Estrella, and Recompense. The mining method used at all three mines is cut and fill stoping.
The operation currently produces approximately 430 tpd of oxide ore and 870 tpd of sulphide ore. Each type of ore is processed through separate circuits which share a single crushing plant. The daily processing capacity of the oxide plant is nominally 650 tonnes of ore and the capacity of the sulphide plant is nominally 750 tonnes.
