Mineral Resources Limited (MinRes) has resumed transport on a private Pilbara haulage road from its Ken’s Bore mine to Port of Ashburton following a temporary closure due to numerous truck rollovers at the site.
In an announcement released to shareholders, MinRes advised “haulage operations resumed on the Onslow Iron dedicated haul road on the evening of 21 March 2025”. Operations had been closed since March 18, when the most recent of the rollovers occurred.
“MinRes reported to WorkSafe WA that the rear two trailers of a road train had tipped onto their side on the haul road on 17 March 2025,” the company previously said in a statement.
“The prime mover and first trailer remained upright, and the operator was not injured.”
While the road was closed, haulage continued via contractor vehicles using alternative routes, while MinRes says it “strengthened control and traffic management” on the haul road.
The reopening of the road has come following “constructive discussions with Worksafe WA regarding controls and risk mitigation”.
FY25 Onslow Iron volume guidance is maintained.
MinRes has also announced the commissioning of a new transhipper, MinRes Rosily, to help bolster the production ramp-up of Onslow Iron.
The new transhipper arrived in Exmouth in February and travelled to Onslow for testing and commissioning before recently commencing operations.
Onslow Iron’s nameplate capacity is now 35 million tonnes per annum. Each fully-enclosed MinRes transhipper measures 123 metres by 36 metres and has capacity to transport 20,000 tonnes of iron ore to ocean going vessels anchored 40 kilometres from Port of Ashburton.
