Mineral Resources Ltd (MIN.AU) saw its stock price plummet by 7.96% during intraday trading on Wednesday, following news of a temporary pause in haulage operations at its Onslow Iron project in Western Australia. The sharp decline comes after the company reported a road train accident on its haul road earlier this week.

According to a statement from Mineral Resources, the rear two trailers of a road train tipped onto their side on the haul road on March 17, 2025. The incident was promptly reported to WorkSafe WA, the government agency responsible for workplace safety in the mining sector. As a result, the company has temporarily suspended commercial transport of goods on the Onslow Iron Haul Road while an internal investigation into the cause of the accident is underway.

Despite the setback, Mineral Resources has taken steps to mitigate the impact on its operations. The company stated that haulage is continuing through contractor vehicles using alternative routes. Furthermore, Mineral Resources expressed confidence that it expects to resume haul road operations without affecting its FY25 Onslow Iron volume guidance. This assurance may help alleviate some investor concerns, although the market reaction suggests ongoing uncertainty about the incident's potential long-term implications for the company's performance.
