Prominent Hill achieving design throughput – Oz Minerals miningweekly.com By: Creamer Media Reporter 4th May 2009 JOHANNESBURG (miningweekly.com) – Australia’s third-largest diversified miner, Oz Minerals, said on Monday that its flagship Prominent Hill copper/gold mine was achieving its design throughput rates, about a month after delivering its first ore shipment in April. Oz Minerals executive GM for project and technical services John Nitschke said the processing plant at the mine, in the north of South Australia, was routinely achieving desired performance. “The processing plant is running constantly at around 1 050 t/h throughput, we are achieving head grades averaging 1,55% copper and 0,5 g/t gold, and are now focussed on getting metal recoveries up to the target rate of 88%,” Nitschke said at the Paydirt 2009 South Australian Resources & Energy Investment Conference. “We have also delivered four months supply of ore feed onto Prominent Hill’s run-of-mine stockpile and intend to keep that supply feedstock up. There are many indications that the overall processing operation could well go beyond its design capacity as long as we can keep the ore feed up to it.” Nitschke stated that the company had taken aboard a policy of supporting the local economy as much as possible in the design, equipment ordering and construction phase. “On our numbers, the company in developing the mine, has injected A$470-million into Adelaide’s economy, A$25-million into regional South Australia and A$4-million specifically into Cooper Pedy.” He noted that the total of this expenditure represented about half the project’s total cost premining start. More than 60% of Prominent Hill’s overburden material, which was about 71,8-million bank cubic metres (bcm), has so far been removed, along with 6,l-million bcm of waste and 2,3-million bcm of ore. The highest grade portion of the ore body is now exposed in the bottom of the open pit.
