The Australian mining sector has reportedly had mixed performance. On the negative side, exploration expenditure fell 6.8% to AU$655 million in the June 2020 quarter and revenue has fallen by an estimated 14.1% over 2019-20. The largest decrease by minerals sought during exploration activities came from expenditure on selected base metals. Additionally, Australia's aluminium is being priced out of the global market due to high energy costs as global demand has slumped causing aluminium producers to consider the viability of their facilities.
