Kipushi is centred on a hydrothermal polymetallic vein deposit and is clearly associated with a set of intersecting faults estimated to be some 600-650 million years old. This makes the deposit distinct from the stratiform copper/cobalt deposits that predominate on the Congolese/Zambian Copper belt. The Kipushi deposit is located on the north limb of an anticline structure in close association with the fault zone cutting dolomitic rocks belonging to the Kundelugan system. It comprises a zone of stringer, massive and semi-massive sulfides about 600 m long and 15 to 75 m wide, striking in a north-easterly direction and dipping about 70º to the northwest. The sulfides occur in the fault plane, in joints, fractures and bedding planes in the dolomite and as subvertical chimneys in carbonate rocks. The orebody has been traced from surface down to the 1,800 m level and it is open at depth.
