Downer EDI Limited (Downer) announced today that it had been awarded a contract with OZ Minerals Carrapateena Pty Ltd (OZ Minerals), valued at approximately $660 million over six and a half years, to provide underground mining services at the Carrapateena copper gold project in South Australia.

The scope of work to be carried out by Downer includes:

•  site setup and development to the top of the ore body and infrastructure excavation;

•  production setup and ramp up; and

•  bedding in steady-state operations at nameplate site capacity.
