NRW Holdings has won a $180 million contract at Rio Tinto’s Nammuldi iron ore mine in the Pilbara.
The contract will include bulk earthworks for the processing plant, mine service facilities, a stockyard and an explosives compound.
The project is expected to run for 37 weeks, with a peak workforce of more than 400 people.
NRW has been the front runner of many major mining projects of late.
The company won a $140 million drilling contract for Fortescue Metals' Cloudbreak mine in February.
While in October, they were awarded a $90 million contract as part of Rio Tinto's Yandi Sustaining Project for its Yandicoogina iron ore mine.
Earlier this year, Rio Tinto announced an expansion of its iron ore operations in the Pilbara with a $3 billion dollar investment set to create more than 2000 jobs in the region.
Premier and state development minister Colin Barnett said the West Australian economy was set to benefit from the investment.
“This major investment by Rio Tinto will create almost 1 500 construction jobs and secure ongoing employment for more than 700 people,” Barnett said.
“The Nammuldi mine, 60km north-west of Tom Price, includes a major investment in mine infrastructure, which will see iron ore mined below the water table and increase the mine’s production limit from eight to 23 million tonnes a year.
