Joint venture partners Downer EDI and Ausenco have been awarded a $312 million contract at OZ Minerals’ Carrapateena copper-gold project in South Australia.

The scope of works includes engineering, procurement and construction (EPC) of a new minerals processing plant, including the non-process infrastructure to support the operations.

Downer and Ausenco have also been contracted for site power distribution, plant bore fields development for regional water supply, and full communications and telemetry network.

The JV will start work under a limited notice to proceed (LNTP) agreement, with these activities valued at around $100 million.

Construction of the plant is scheduled to launch at the end of first quarter 2018. The full contract is estimated to be worth around $312 million.

Downer chief executive officer Grant Fenn said the Carrapateena project would play a critical role in boosting the existing and future copper export capacity for OZ and South Australia.

“Today’s announcement builds on the joint venture partners’ extensive and specialist skills in the development of large-scale materials handling infrastructure and combines Downer’s national construction expertise with Ausenco’s world-class mineral processing capability,” Fenn said.

Ausenco chief executive officer Zimi Meka said the JV and OZ had already developed excellent working relationships.

“With our complementary values, people, approaches and absolute commitment to a safe and cost-effective project, we are delighted to be working with Downer and look forward to delivering a successful project for OZ Minerals,” Meka said

OZ officially approved development of the $916 million Carrapateena operation in August. It expects to be producing from the mine in the second half of 2019.
