MK became a savior of sorts when it employed over 10,000 locals during its work on the Cerrejon coal mine.
It’s located in the basin of the Rancheria River, southeast of La Guajira Department in Colombia. It is an open-pit mine, and is one of the largest mines in the world. The coal mine was divided into three main corresponding areas Cerrejon North Zone, Cerrejon Central Zone and Cerrejon South Zone. The mine extends over 170,000 acres where the company moved 80,000,000 cubic yards of rock and dirt annually.
