Thiess has won a $2.3 billion contract to extend operations at the Lake Vermont coal mine in Queensland.
A new six year agreement will expend the contract's current operations and double production from four million tonnes to eight million tonnes per annum.
It expands the company's current work on mining and maintenance at the coal mine.
Bruce Munro, Thiess' managing director, said this large contract is an endorsement of the relationship between Thiess and mine owner Jellinbah Group, which began with Thiess' work at the mine in 2007.
"Thiess is very proud to continue its involvement at the Lake Vermont mine where we’ve been working with the Jellinbah Group from the very beginning to plan, build and operate the mine," Munro said.
Jellinbah CEO Greg Chalmers added that Thiess's continuation of work at the mine will "ensure the ongoing delivery of cost competitive coal from the mine".
The existing site team at Lake Vermont is gearing up for the new contract and is "mobilising ultra-class mining fleets to meet the increased production requirements and we are truly excited by the opportunities this brings to the people of the Dysart area," Thiess' Australian Mining executive general manager Michael Wright said.
Lake Vermont is around 20 kilometres north of Dysart and has a workforce of about 350.
