AusGroup subsidiary AGC Industries has formalised its construction contract with Gindalbie Metals for its Karara iron ore project.
The contract, worth more than $160 million, follows on for the award of the early work contract in March last year.
It consists of structural, mechanical, and piping installation works at the magnetite mine,.
AusGroup CEO Laurie Barlow said "this contract further strengthens the successful relationship between AGC and Karara Mining".
To date, AGC have completed the early works contract, as the mine begins peak construction in the lead up to first production in early September.
It has a workforce of 530 already on site at Karara, with the potential to increase this number to around 700 for peak activities.
