A Downer JV Has Been Awarded a $312 Million EPC Contract from OZ Minerals


A JV between Downer and Ausenco has been awarded a $312 million for OZ Minerals’ Carrapateena copper-gold mine.

According to Downer, the initial works on the contract are valued at around $100 million. It is expected though that the full value of the contract will reach $312 million.

The scope of works stipulated in the contract includes engineering, procurement and construction (EPC) of a new minerals processing plant for OZ Minerals’ Carrapateena copper gold mine in South Australia.

Construction on this project is expected to begin at the end of the first quarter of 2018.

Downer’s chief executive officer Grant Fenn spoke about the significant project;

“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.

“We look forward to working closely with Ausenco and bringing innovative and efficient solutions to OZ Minerals.”


Details on the Carrapateena Copper Gold project

Carrapateena is located in South Australia on the eastern margin of the Gawler Craton.

One of Australia’s largest undeveloped copper deposits, the project will be a 4.25 Mtpa underground operation, with an estimated mine life of 20 years. Infrastructure on site includes an accommodation village, airstrip, processing plant and tailings storage facility.

Construction of Carrapateena is underway and commissioning is scheduled for Q4 2019 after which the project will ramp up to steady state production.

There are two main phases to construction:  

Phase one Q3 2017 – Q1 2018 (underway): construction commences on the accommodation village and airstrip, and development of the dual access decline continues.  

Phase two Q2 2018 – Q4 2019: subject to mining lease approval, phase two includes construction of above ground infrastructure, processing plant, tailings storage facility, western access road, power line and installation of the underground materials handling system.
