Project description An independent feasibility study on the Kamoto mine has just been completed. The study confirms the proposed approach of a phased redevelopment and restoration of economically-viable operations within a very short time, with low capital costs relative to the restored-production capacity.
The mine requires only limited work to restore production. A new trackless equipment fleet will be bought. The existing pumping infrastructure will be upgraded and new ventilation fans will be installed. Limited maintenance of the remaining infrastructure will be required. Mining can begin almost immediately once the equipment arrives on site. Mining will be a combination of the historical room-and-pillar system and newly-introduced longhole retreat stoping. The use of longhole retreat stoping will increase resource recovery to an estimated 80%, as well as improve operational flexibility. Backfill plants will be required to carry out this mining system. The mine's concentrator is currently operating on a limited basis as ore becomes available. Initial work will consist of general maintenance to the plant and mills. Over time, the concentrator will continue to be upgraded as production increases. Beginning in phase three, and continuing to the beginning of phase four, new flotation cells will be added to the circuit. The Luilu metallurgical plant will undergo refurbishment to restore it to a reliable operating state. The plant flow sheet will be retained. However, new filter technology and two new roasters will be added to the plant during the different phases. A substantial resource exists within the Kamoto mine, and an early drilling programme is planned to upgrade high-grade resources in this area with the expectation that beneficial modifications to the current mine plan will follow with more information. The property also hosts several high-quality exploration targets that will be evaluated after operations resume. Value Phase one through four capital expenditure will amount to $426,7-million (+20% to -10%).
Duration The project will be carried out over four years.
