The Central African Copperbelt is a world-class metallogenic province which stretches from the Copperbelt Province in Zambia, through the Katangan Province of the Democratic Republic of Congo and into the North- Western Province of Zambia. The Lumwana Project lies within the North-Western Province of Zambia and contains two major copper deposits, Malundwe and Chimiwungo, which are structurally controlled shear zone hosted deposits considered to be an end member of Central African Copperbelt class of deposits. The Lumwana Project consists of two major copper deposits, Malundwe and Chimiwungo. Malundwe is the smaller deposit but has a higher copper grade and contains discrete zones of uranium and gold mineralization with occasional sporadic high cobalt (>0.1%). Chimiwungo is a much larger deposit that is lower in copper grade and contains a number of significant high grade (>0.1%) cobalt zones in addition to some uranium mineralization. Chimiwungo can be sub-divided into the Chimiwungo Main, Chimiwungo South, Chimiwungo North and Chimiwungo East mineralized zones. The copper mineralization at Malundwe (including Kanga) and Chimiwungo is hosted almost entirely within high grade metamorphosed, intensely mylonitized, recrystallized muscovite–phlogopite–quartz–kyanite schists with disseminated sulphides (typically <5%) dominated by chalcopyrite and bornite which is locally referred to as Mineralized Ore Schist. The ore host, Mineralized Ore Schist, has an intensely transposed ........

There are two mining areas; Malundwe and Chimiwungo, which are 7 km apart in a direct line. Malundwe was the first pit to be mined, commencing in 2008. However Chimiwungo now contains 93% of the remaining reserves. The Chimiwungo mining area consists of three separate pits; South, Main and East. Malundwe was the first pit to be mined, commencing in 2008. However Chimiwungo now contains 93% of the remaining reserves. The Chimiwungo mining area consists of three separate pits; South, Main and East. Sulphide copper ore at Lumwana is mined by open pit methods that follow the typical sequence of tasks: grade control drilling, blasthole drilling, blasting, loading by hydraulic shovels (15 m3 and 27 m3 ), and hauling by off-highway trucks (254 t). The mine started operations in 2008, and now mines an average daily capacity of 260,000 t of total material mined. Mining is done primarily by Lumwana personnel and equipment; however production is also supplemented by a contractor with specialized small articulated fleet of trucks to meet pre-stripping requirements, particularly the stripping of weathered material in the wet season. They use 40 tonne capacity Volvo articulated trucks and 90 tonne tracked excavators. The contractors move 45,000 tonnes per day and are scheduled by the Lumwana Mine Engineering Department to coordinate material movements. During the fourth quarter of 2022, Barrick began a transition to an owner miner fleet at Lumwana. With the transition, Lumwana will inv ........
