The Koolan Island hematite mining operation is located approximately 140 kilometres north of Derby in Yampi Sound, off the northern Kimberley coast of Western Australia. Almost 70-million tonnes of high-grade (Fe @ 67%) iron ore were mined by BHP from Koolan Island from 1959 to 1993.
Koolan iron ore is very high quality and low in impurities. Mount Gibson acquired the project through its successful takeover of Aztec Resources in early 2007. Hematite shipments commenced in June 2007, and passed the 20 million tonne milestone in February 2014.
Operations were suspended in November 2014 following a seawall failure which resulted in the flooding of Main Pit. The operation is currently being reviewed to determine options to rebuild the Main Pit seawall and resume large scale production.
