Managing water consumption in mining

Water for the project has to be sourced from two dams and Lake Argyle, meaning it could have potential impacts on ground water. In 2005 the mine used more than 3,500 megalitres of water from the lake to run operations. By 2009 they had reduced this to 300 megalitres – a 95% drop.
