The Nkana Mine produces copper and cobalt ore from four sources: North Shaft, Mindola Sub Vertical, Central Shaft and South Ore Body ("SOB"). In addition, Nkana was produced copper from open pits. All the open pits are exhausted except "Area Nose" and area J, both of which were placed on care and maintenance in 2019.
