Australia’s third-largest copper-gold producer, OZ Minerals, is planning to begin production of copper from its underground mine at Carrapateena by 2019. The construction plan has been revised to AUD$975 million from the original plan of AUD$3 billion in 2014. The mine is expected to produce about 67,000 tonnes of copper and 76,000 ounces of gold per year during the first three years of operations. The plan is to mine 4 million tonnes per year, with copper concentrate starting in 2019. The total expenditure by OZ Minerals includes a $150 million concentrate treatment plant, infrastructure and port options. The mine is to be located 130 km north of Port Augusta in South Australia and 100 km south-east of BHP Billiton’s copper-uranium Olympic Dam mine. OZ Minerals is also holding discussions with the steel company, Arrium Ltd.
