Bis has had its haulage and site services contracts for Minara Resources at the Murrin Murrin mine in the north-eastern Goldfields extended by four years.
The Brad Rogers-led mining logistics company said it had delivered a range of services at the Murrin Murrin site since the operation begun in 1998.
The services provided include haulage and haul and road maintenance services, calcrete services, and bulk logistics services.
"We are proud to have been part of the Minara operations for over 20 years, working in collaboration with Minara to deliver safe and innovative solutions that add value to their operation," he said.
"We look forward to continuing our successful relationship with our colleagues at Murrin Murrin.”
