With the exception of Tilwezembe Mine, all of the mineralized properties of KCC are localized within the Kolwezi Nappe, a northeast striking synclinal basin with major and minor axes of approximately 20 km and 10 km respectively. Tilwezembe Mine is located about 20 km to the east of Kolwezi.

The mineralized zone of Tilwezembe is located in a northeast-southwest anticlinal structural lineament, which extends further to the east where known copper and cobalt deposits (Kisanfu, Myunga, Kalumbwe and Deziwa). Strongly brecciated siliceous dolomites and shales of the Mwashya Formation (or R4) dominate with interstitial bands of haematite and oolites. The strata strike almost east-west and dips at about 45° to the south.

The mineralization at Tilwezembe Mine is atypical being hosted by the Mwashya or R4 Formation. The mineralization generally occurs as infilling of fissures and open fractures associated with the brecciation. The typical mineralization consists mainly of copper minerals (chalcopyrite, malachite and pseudomalachite), cobalt minerals (heterogenite, carrolite and spherocobaltite) and manganese minerals (psilomelane and manganite).

Tilwezembe Open Pit (Kananga) The cobalt-rich Tilwezembe open pit operation is located 30 kilometers southeast of Kolwezi.

The historical drilling was undertaken by GCM, and the information was the basis for the first Mineral Resources estimates for Tilwezembe Mine undertaken by SRK. The drilling information included holes on a 25 m spacing within the operational Tilwezembe pit and 100 m x 50 m on Tilwezembe East.

The procedures adopted during the sampling of the cores from Kananga and Tilwezembe are similar.

KTC currently comprises the following operations. Ore crushing and milling
- Oxide ore crushing and milling section treating mixed ore; and
- Sulphide ore crushing and milling section treating sulphide ore Flotation
- Oxide ore flotation treating mixed ore; and
- Sulphide ore flotation treating sulphide ore.

Concentrate handling The Luilu Plant currently comprises the following operations:
- Concentrate Receiving;
- Roasting;
- Leaching;
- Copper circuit;
- Cobalt circuit;
- Solvent extraction;

Mixed ore from the KOV OP is transported by truck and stockpiled near the oxide crushing area. It is blended before being crushed by jaw crushers and conveyed to stockpiles in the milling section.

Milled mixed ore is processed in the flotation circuit to produce a final sulphide concentrate, a final oxide concentrate, and a tailings stream. This is achieved by first treating the milled mixed ore in a roughing s ........
