Mineral Resources (MinRes) and WorkSafe WA have declined to elaborate on safety changes to a private haulage road where six trucks have rolled in under a year. The mining company built the $2.6 billion road in the state's north to transport iron ore 150 kilometres from its Ken Bore mine to Port of Ashburton. Since August there have been six truck accidents, the most recent last week. Two days later, after receiving a notice from WorkSafe WA regarding "controls and risk-mitigation of the road train operations", MinRes briefly paused haulage. Operations resumed on Monday after "constructive discussions with WorkSafe WA", the company told shareholders. Shareholders felt the brunt of the shutdown with MinRes' share price dropping almost $4 to $21.87 on Wednesday afternoon last week. In the days since, the share price has started to recover. MinRes has refused to elaborate on what safety changes have been made, and WorkSafe WA said it would not publish the notice issued to MinRes. The WA government department has declined to comment further. Local concerned by truck rollovers The road, once described by MinRes as "one of Australia's most impressive pieces of transport infrastructure", is part-owned by international investment firm Morgan Stanley. Onslow resident Ashley Norton said he and others in the community were concerned over the prospect of increased haulage on public road networks due to safety issues on the private road. During the haulage pause, contractor trucks used the North West Coastal Highway, Onslow Road, and Warrida Road to cart iron ore — all primarily dual-lane roads with little room for overtaking. An emergency services volunteer, Mr Norton said the prospect of more trucks on the road could mean headaches during emergencies. "Should something like that happen there's no capacity to actually [drive] around whatever incident there is," he said. Mr Norton is frustrated by a lack of community consultation and wants to see MinRes and road authorities engage more with concerned locals. Plan for autonomous road trains The mining company plans to have autonomous road trains, each capable of carrying 330 tonnes of ore, on the road this year. The project represents Mineral Resources' attempt to innovate pit-to-port transport, setting itself apart from the region's mining giants. The road was also damaged this year by heavy weather, leading to major resurfacing works. David Cliff, a mines safety expert at the University of Queensland, said it was "surprising" it took six rollovers for haulage to be paused. "One may occur because of storm damage, but once one of those events has occurred there should be corrections put in place to make sure that doesn't happen again," Professor Cliff said. Professor Cliff said incidents like these could have a major impact on a company's reputation. MinRes was rocked by scandal in 2024 when managing director and founder Chris Ellison announced he would step down amid allegations of tax evasion. At the time MinRes said the scandal had adversely impacted its reputation and economic confidence. Mineral Resources did not respond to specific ABC questions regarding the road's ongoing safety.
