Kipoi Central is the principal deposit at the Kipoi Project, and contains a zone of high-grade copper mineralisation within a larger, lower grade global resource.
In December 2013, the Measured and Indicated Resource at Kipoi Central was 29.1 million tonnes at 1.7% copper for 623,500 tonnes of contained copper and the Inferred Resource was estimated at 1.8Mt at 1.1% copper for 19,000 tonnes of contained copper. This estimate was completed by Cube Consulting Pty Ltd to update the estimate from May 2012 following additional drilling and incorporating the mining depletion at Kipoi Central to 30 November 2013.
In January 2014, an updated Ore Reserve estimate for the Kipoi Central deposit completed by Cube Consulting increased to 30.14Mt at 1.31% Cu for 394,500 tonnes of contained copper.
The increased reserve at Kipoi Central will be mined and processed through the Stage 2 solvent extraction electrowinning (SXEW) plant which commenced copper cathode production in May 2014.
