A copper-cobalt mine owned by ZCCM. The deepest mine on the Zambian copperbelt. Two shafts below 1,300 meters and 3 small open pits until 1984.

The mine exploits reduced facies type copper-cobalt ore beds, hosted in sedimentary rocks of the Lower Roan group along the southwestern margin of the Kafue Anticline. Along their strike length of 14 km, the beds are frequently replaced by siliceous dolomite, forming barren gaps. They also are cut by veins with U-Mo-V mineralization. The Rokana deposit consist of the Mindoa, Central and South orebodies.

A 1975 discovery yielded the largest and finest libethenite crystals ever found.
