Sediment-hosted stratiform Cu deposits, one of the most important types of copper deposits all over the world, are always prospecting targets for mining companies. The Neoproterozoic Central African Copper-Cobalt belt is one of the greatest sediment-hosted stratiform Cu-Co provinces in the world. The deposits are stratabound and mostly restricted to the Roan Group within the Lower Roan Ore Shale (LOS). The Chambishi Cu mine is a successful project for Chinese companies operated in Zambia. This work presents comprehensive studies of the geological features, ore-forming background, diagenetic and mineralization processes in the Chambishi Southeast ore district. The results reveal that the host rocks and orebodies are strictly controlled by the paleo-sedimentary environment and the paleo-topography of basement, the orebodies were formed in an epeiric shallow sea evaporitic environment and has experienced a major marine transgression-regression process. A full understanding of the geologic features and distribution of the sediment-hosted stratiform Cu deposits in Zambia is helpful for exploration and mining investments. The Copperbelt Province and North-West Province have great potential for prospecting copper and cobalt deposits in the future.
