Australia's third-biggest gold miner, Evolution Mining, has approved a $250 million expansion of its Mungari operations near Kalgoorlie, despite concerns about the overheated construction sector. 

The expansion would more than double the capacity of the processing plant from 2 million tonnes a year to 4.2 million tonnes.
