El Boleo
From Wikipedia, the free encyclopedia
El Boleo is a copper-cobalt-zinc-manganese deposit located adjacent to the port city of Santa Rosalía, Baja California Sur in Mexico. It includes a historic open pit copper mine, as well as underground workings. Mining began in the 1860s, and continued, off and on, until the 1980s. The property is currently under development by a consortium of Korean companies led by Korea Resources Corporation. Preliminary underground mining began in 2012. The $1.75 Billion project is scheduled for completion in 2013.
