BHP Billiton has spent $US8 billion over the last six years on improvements to Escondida, the giant copper mine in Chile in which it and Rio Tinto own stakes of 57 per cent and 30 per cent respectively. Escondida is tipped to produce between 1.13 million and 1.23 million tonnes of copper in 2018, and BHP is aiming for annual production of 1.2 million tonnes per annum over the next decade. However, the quality of the copper grade produced by Escondida is expected to decline over this period.
