Epiroc will continue to support Roy Hill as it enters the final stage of its autonomous haulage system (AHS) from March 2023. This will convert Roy Hill's mixed fleet of 96 haul trucks to driverless operation, creating the world's largest autonomous mine. The project's production verification phase is complete, and 10 haul trucks have been converted to driverless operation using ASI Mining's Mobius traffic management and on-board automation systems to navigate the mine's virtual map and communicate with other vehicles and with the Remote Operations Centre (ROC) in Perth.

The AHS fleet is meeting the desired safety and productivity metrics and achieving higher productivity rates than the conventional haul truck fleet, which was a key objective of the program over the past two years. The autonomous haul trucks are running 24/7 in a dedicated autonomous operating zone, interacting safely with two excavators and numerous ancillary vehicles at intersections, waste dumps and load areas. The project's progressive expansion will see autonomous haul truck numbers grow steadily from March 2023 and throughout 2023.

The fleet will comprise 54 Caterpillar trucks and 42 Hitachi trucks. In addition, more than 200 ancillary vehicles will interact with the autonomous haul trucks.
