Minerals

Infrastructure upgrades and maintenance, mine closure, plant decommissioning and demolition, tailings management, and progressive rehabilitation across the resource lifecycle.

The Challenge

The Australian minerals sector is upgrading and closing assets at scale. As coal mines transition to closure across the Hunter, Bowen and Latrobe Valleys, and legacy alumina, lead, zinc and copper smelters also approach end-of-life; upgrades to ageing infrastructure in Western Australia are needed to meet continued demand for iron ore.

Boards face mounting pressure to demonstrate that closure liabilities are not just provisioned but actively executable, with balance sheet rehabilitation provisions a material factor in corporate valuations.
