Fortescue Metals Group will convert dozens more haul trucks at its Pilbara iron ore operations to autonomous system technology.

Under an 18-month contract announced on Thursday, CIMIC mining services provider Thiess will install the driverless technology in at least 65 Komatsu 930E and Caterpillar 789D trucks at FMG’s Christmas Creek operations, along with ancillary equipment across the miner’s Chichester hubs.

The value of the contract was not disclosed.

Thiess Managing Director Douglas Thompson said: “We are pleased to continue working with Fortescue to deliver autonomous systems to its mining fleet.

“Our work at Christmas Creek builds on our strong record of delivery for Fortescue at their Solomon Mine, where we assisted in the upgrade of their autonomous fleet.”

FMG marked a significant milestone earlier this year after trucks fitted with the AHS technology started operation at Christmas Creek.

The conversion of 100 haul trucks at its Chichester hub made the mining giant the first iron ore operation in the world to have a fully autonomous fleet.

Since the introduction of the technology at Solomon in 2013, AHS trucks have moved more than half a billion tonnes of material and achieved an increase of more than 30 per cent in productivity levels.
