Stage 1 is processing a high-grade zone of copper mineralization at Kipoi Central through a heavy-media separation plant and is expected to produce a total of 132,000 mt of copper in concentrate over a 42-month operating life.
The stage 2 feasibility study confirmed the project as a low-cost, high-margin operation capable of producing 538,000 mt of copper cathode over 11 years, processing ore reserves from the Kipoi Central, Kileba, and Kipoi North deposits and reject floats, slimes, and medium-grade ore stockpiles from the stage 1 heavy-media separation operation.
Current planning calls for construction of a heavy-media separation plant to process 250K-mt/yr surface-mined ore.
