Cerro Matoso nickel operation
Cerro Matoso has historically been the lowest cost ferronickel producer in the world. However, it is faced with declining ore grades which is increasing operating costs. BHP Billiton had been looking at options, including heap leaching of low grade ores, which could lead to the doubling of capacity at Cerro Matoso. In 2014, BHP spun off Cerro Matoso as part its move to divest non-core assets into a new company, South 32.
