BHP and the South Australian government are close to finalising talks over a multibillion-dollar desalination plant for the Upper Spencer Gulf as the miner grows more confident in its ability to deliver a 55 per cent production boost at its nearby copper mines.
Reporting a $US6.6 billion ($10.1 billion) underlying profit for the six months to December 31 on Tuesday, BHP outlined a clearer pathway to grow its SA copper division to produce more than 500,000 tonnes of the metal each year.
