Mineral Resources Limited (ASX: MIN) is hosting an investor and analyst tour of Onslow Iron on 27-28 May 2025, including a visit to Ken’s Bore and the project’s Port of Ashburton operations.
MinRes advises Onslow Iron volume guidance has been revised to 7.8 to 8.0 million tonnes (13.8-14.1Mt, 100% basis), from 8.5-8.7Mt previously. The reduction relates to lower than expected availability of contractor road trains for haulage (actual 65 vs 85-100 target) and below-forecast daily cycles (actual 2.7 vs 4.0 target), despite a steady ramp-up of haulage volumes and as-expected performance of MinRes jumbo road trains.
For the month of May 2025 to date, Onslow Iron has shipped 1.7Mt. Over the past seven days, an average 74kt/day was loaded onto ocean-going vessels, with several days during May above 80kt, and 100kt loaded on a single day. It is expected that 1.9Mt will shipped during May (April 1.3Mt), equivalent to a run rate of 23Mtpa.
The significant month-on-month increase highlights the acceleration of Onslow Iron’s ramp-up, with the project remaining on schedule to achieve its nameplate capacity of 35Mtpa in Q1 FY26.
MinRes anticipates shipping circa 2.3-2.6Mt in June, equivalent to 75-87kt/day and a run rate of 28-31Mtpa.
The fifth transhipper, MinRes Peak, is currently in commissioning at the Port of Ashburton, with the imminent arrival of its tug further increasing transhipping capacity.
