From 26 September 2025, contractor road trains operating at Onslow Iron transitioned off public roads and solely onto the 150-kilometre private haul road.
A progressive ramp-down of contract road trains will commence at the end of September and continue through to the end of October. MinRes now has its full fleet of 140 jumbo road trains on site, with an average of 120 in operation.
Notwithstanding the roadworks, the project shipped a record 3.2 million tonnes of ore in August 2025.
Roadworks included seal binder upgrades and cement stabilisation to enhance pavement strength and moisture resistance, as well as asphalting along the entire length of the road. Minor ancillary works off the road continue and are scheduled for completion next month.
The width of the private haul road spans 11 sealed metres from edge to edge, two metres wider than typical public roads used for heavy haulage in the Pilbara region.
"Onslow Iron has continued to perform very strongly even during the upgrade of the private haul road," said MinRes Managing Director Chris Ellison.
"The resumption of unconstrained haulage marks another significant milestone as we focus on safely delivering the project's FY26 volume guidance.
"Onslow Iron is now established as a cash generative, low-cost asset that underpins the deleveraging of our balance sheet while driving stable, long-term growth."
