The feasibility study confirmed the viability of a stand alone processing facility at Lumwana producing concentrate on-site and utilising the Roast-Leach-Electrowin (RLE) process route to produce LME grade copper cathode. The state-of-the-art process plant is designed to treat 18 million tonnes per year of sulphide copper ore stream from both ore bodies to produce 400,000 tonnes copper concentrate per year and during years 6 to 20 when the RLE Plant is commissioned, 100,000 tonnes copper cathode, 1,000 tonnes cobalt powder and 230,000 tonnes concentrated sulfuric acid per year.
The development schedule for Lumwana indicates that the Lumwana project could be brought into production by 2006. Following completion of the study the critical financing stage should take approximately 12 months. This will lead into an 18-month construction period, and commissioning, with production estimated to commence in 2006.
Robert Rigo, Equinox Copper Ventures Project Manager for the Lumwana Project commented "we are very pleased with the comprehensive bankable feasibility study that Aker Kvaerner Australia has delivered and given the favorable Zambian development environment for copper we are optimistic regarding the future of developments of this kind".
The study was completed in the Aker Kvaerner Australia's Perth Office. Aker Kvaerner Australia's contract was for AUD 2.5 million with the total BFS valued at USD 13 million. The completed study covered infrastructure, mining and processing and included preliminary design, engineering and cost estimates for the proposed mining, process plant and associated facilities.
Paul Swinyard, Regional Manager for Aker Kvaerner Australia advised, "We have had positive feedback from the client and look forward to supporting Equinox in the next critical stage of this exciting development".
