Mopani Copper Mines mineralisation occur within the ore shale. Copper mineralisation in the deposits changes from mostly chalcopyrite in the South Orebody, to chalcopyrite-bornite in the Central area and to bornite-chalcopyrite at Mindola. Cobalt occurs as carrollite and cobaltiferous pyrite in approximately equal proportions. The mine produces copper and cobalt from three sources: Mindola Shaft, Central Shaft and South Orebody Shaft. Vertical crater retreat is the predominant mining method while sublevel open-stopping and sublevel caving methods are also used. In April 2011 Mopani announced its intentions to sink a new $295 million shaft at Mufulira, this should extend the life of the mine
