DOWNER AWARDED FIVE YEAR MINING CONTRACT EXTENSION

Downer EDI Limited (Downer) today announced it had been awarded a contract by Millmerran Power Partners to continue the provision of mining services at the Commodore open cut coal mine in South East Queensland. The project is located adjacent to the Millmerran Power Station, approximately 200 kilometres west of Brisbane.

The contract extension is for an additional five-year term and is valued at $286 million. This will see Downer continue operations at Commodore until the end of August 2024.

Downer has been providing a total mining service at Commodore since 2001 to deliver coal to the Millmerran Power Station.

The scope of works includes operating and managing the mine and associated activities, including mine planning and design, drill and blast, overburden removal, coal mining and rehabilitation. Downer also holds statutory responsibility for the mine site.

The Chief Executive Officer of Downer, Grant Fenn, said the contract extension was a clear demonstration of Downer’s ability to deliver value for its customers.

“We are delighted to be continuing this 17-year partnership,” he said. “Downer has a strong record of providing mining services to Millmerran Power Partners and helping it to drive efficiencies across its operations. We look forward to extending our working relationship and continuing to deliver efficient solutions for the Commodore mine,” Mr Fenn said.

The contract builds on Downer’s recent successes in the mining, energy and resources and industrial sectors with the award of a $120 million mining services contract at the CSA mine in New South Wales, a five-year maintenance and support services contract at the Chevron-operated Gorgon and Wheatstone facilities in Western Australia, and a $660 million underground mining services contract at the Carrapateena copper gold mine in South Australia.
