Olympic Dam Tailings Dam Embankment Raising

York Civil was engaged in an eight year contract with Western Mining Corporation to continually raise 11km of tailing dam embankments, to assist with the ongoing expansion and production of the Olympic Dam multi-mineral mining operation.

The contract went through various extensions and transferred to BHP Billiton when they acquired Western Mining Corporation in 2005.
