Carina ore to be Exported out of the Port at Esperance
At the end of January, 2016, Mineral Resources, trialled train haulage movement to the closer port at Esperance, in preference to the port at Kwinana, to export its Carina Yilgarn iron ore product from Australia. The company believes it can make a savings of $10 for each tonne of ore, by shipping its product out of the Esperance port. To this end it has entered into discussions with the Esperance port management, Southern Ports Authority, grain exporter CBH and Brookfield Rail, in order to progressively transfer its ore exporting from the Kwinana port.
