Downer has secured a four year contract extension with Karara Mining until March 2022.
The additional work will add around $350million in value.
Downer CEO Grant Fenn said he was pleased with the new contract, and development of their ongoing relationship.
“This extension is an endorsement of Downer’s strong safety and productivity performance and we look forward to bringing further value to Karara’s operations by reducing operating costs, increasing productivity and enhancing safety,” Fenn said.
The company has been providing mining services to Karara since operations began in 2012.
Last month, Downer won a two year extension for services at Stanwell’s Meandu coal mine and a technical services agreement with Adani.
