The Koolan Island hematite mining operation is in Yampi Sound, off the northern Kimberley coast of Western Australia. Almost 70 million tonnes of high grade (Fe @ 67%) iron ore was mined by BHP from Koolan Island from 1959 to 1993. Hematite production at Koolan Island recommenced in early 2007 with the first shipment achieved in June 2007.

Located 130km north of Derby, works on the project commenced in September 2007 and involved the management and support of a 120t mining fleet and ancillary equipment and up to 30 personnel on site.

This project consisted of the construction of a permanent seawall to allow for the future expansion of a previously decommissioned pit.

The works completed by Brierty involved the construction of the sea wall.
