“Koolan Island is located off the Kimberley Coast of Western Australia, about 80 miles (130 km) north of Derby. The 6,375-acre (2,580-hectare) island is rich in high-grade iron ore and has been open-pit mined since 1963. In 1994 — after 68 million tonnes of ore had been extracted — the mine was temporarily closed and intentionally flooded with seawater, allowing a marine ecosystem to develop within the bounds of the pit. Mining recommenced in 2007 and continues today.”“Koolan Island is located off the Kimberley Coast of Western Australia, about 80 miles (130 km) north of Derby.
