Snapshot	Mufulira underground copper mine is a part of Mopani Operation. The operation produces copper cathodes as its main product. It is one of the most historically significant mines in Zambia, with mining and processing dating back to the early 1920s. The Mufulira asset consists of: underground Mufulira mine, Henderson Shaft, Mufulira Concentrator, Smelter and refinery Acid plants. Mufulira Henderson Shaft is one of the deepest shafts ever sunk in Zambia at 1,547 metres. Shaft development completed in March 2019. The project has added at least 25 years to the economic life of the Mufulira Mine. Mopani Copper Mines PLC has since 2014 sunk and equipped a brand new shaft (Henderson) to replace the old infrastructure at Mufulira mine site.

Deposit type

• Sediment-hosted

Summary:

The rocks of the Mufulira Basin are asymmetrically folded, moderately dipping on the south western flank and sub vertical on the north eastern limb, outcropping at Mokambo on the DRC border. The Roan sediments in the Mufulira syncline in the vicinity of the mine dip at approximately 45º to the north east. Small folds and minor faults are present within the mine area. The Lower Roan arenaceous quartzites and greywackes are the host rocks to the copper mineralisation.

In the Mufulira mining area, the Basement Complex topography appears to have exerted a significant structural control during deformation. The distribution of ore minerals in all three orebodies is stratigraphically controlled, occurring dominantly as disseminations, blebs and irregular masses. The principal copper minerals are chalcopyrite (60%), bornite (40%), and minor/trace chalcocite. Oxide minerals are confined to near surface occurrences, and supergene enrichment zones. Generally the deposit is structurally simple being characterised by three main folds that are in part overturned with a plunge and dip approximately 10º to the northeast. The basin is open and untested at depth.
