That fleet is already onsite and operating at mine, includes excavators, trucks, dozers and other ancillary equipment.
The company said that, combined with the already owned dragline and coal handling and preparation plant, it had the plant and equipment required to achieve its 2 million tonne coal sales profile at the Blair Athol Coal mine for the 2021 financial year and beyond.
Terracom CEO Danny McCarthy said the purchase of the mobile fleet was the final key step for the mine to operate independently.
"We are extremely pleased with and proud of the efforts from the entire team at Blair Athol to complete the transition to owner operator," he said.
"Production levels have remained consistent throughout the transition and this is a testament to the determination from all of the staff and workforce onsite who have adapted to the change in circumstances very well."
