OZ Minerals' new Carrapateena mine has now achieved nameplate mill throughput rate, with stable operational periods at 500t/hr and in excess of 90% runtime achieved for 24 hour periods. Flotation recovery for several shifts has already exceeded 90%, with concentrate grades in excess of 40% copper. The underground crusher and conveyor system are also now operating to design expectations. As previously announced, the larger sub-level cave footprint and optimised mine design is expected to improve cave establishment, enable a faster 12-month ramp-up to the 4.25Mtpa run rate by end-2020 and increase throughput rates to target 4.7­5.0Mtpa from 2023. The processing plant will continue to be tested and optimised through the first half of 2020, and together with the mine production ramp-up this will drive progressively higher throughput and concentrate production during the second half of the year.
