Mineral Resources Limited (ASX: MIN) has announced the safe completion of upgrades to the Onslow Iron private haul road, enabling unconstrained haulage to resume at normal speeds.
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 sealed road. Minor ancillary works off the road continue and are scheduled for completion next month.
Notwithstanding the roadworks, the project shipped a record 3.2 million tonnes of ore in August 2025.
The width of the upgraded private haul road spans 11 sealed metres from edge to edge, 2m 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,” managing director Chris Ellison said.
“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.”
