NRW subsidiary Action Drill & Blast has won a $100 million contract with John Holland at the Isaac Plains mine.
The three year contract will see Action supply explosives and blasting services at the Isaac Plains coal mine.
It has been operating at the mine since July this year on a short term contract, and welcomed the move to a longer term agreement.
Jules Pemberton, NRW's CEO, said "it is pleasing to see Action secure long term contracts with organisations such as John Holland Group".
This agreement comes less than a week after Ausenco won a $66 million contract to provide operations for the Isaac Plains mine's coal handling and preparation plant.
