The Yilgarn Iron Producers Association was formed in 2010 as a consortium of iron ore mining and exploration companies, including Golden West Resources, Radar Iron, Mindax, Legacy Iron Ore, Mineral Resources, Cazaly Resources, and Cliffs Natural Resources, that sought to cooperatively develop rail and port infrastructure to enable their Western Australian iron deposits to be exploited. Overview The Yilgarn iron province extends from Wiluna to Koolyanobbing near Southern Cross, and west of the Leonora-Kalgoorlie-Esperance rail to port infrastructure. The port of Esperance is located about to the south of Kalgoorlie.
