Production numbers released on Tuesday for the miner’s current core mines were broadly in line with analyst estimates, including record first-half output at its Australian iron ore operations. It produced 69.7 million tons of iron ore overall in its second quarter, up 5% on the same period a year ago, and reaffirmed its annual production guidance.

The target has since agreed to tie up with fellow copper heavyweight Teck Resources Ltd.
