Irvine Island (Irvine Island)
Irvine Island is located 11 km off the Kimberley coast of Western Australia in the Buccaneer Archipelago. It is about 250 km northeast of Broome and 140 km north of Derby. Irvine Island is located near Koolan and Cockatoo Islands, on the same iron-mineralized rock formation. Irvine Island has a surface area of 893 ha and is 5 km west of Cockatoo Island.
Irvine Island is composed of rocks of the Yampi Formation, a Paleoproterozoic Statherian-age sedimentary sequence of quartz sandstone, hematitic sandstone, feldspathic sandstone, siltstone, and hematitic conglomerate.
Irvine Island, with two neighboring islands, Koolan and Cockatoo, is part of a belt of iron ore mineralization formed at the base of the Yampi Formation. The ore is mainly of hematite, with small amounts of magnetite. The ore grades laterally into hematitic conglomerate or hematitic sandstone. The sediments of the Yampi Formation were deposited near a shoreline where iron-rich heavy minerals were concentrated on a beach or nearshore bar by prolonged reworking. Mines on Koolan and Cockatoo Islands have been in production since 1951, while the deposits on Irvine island are still in exploration assessment.

The ancestors of Aboriginal Australians began arriving from south east Asia approximately 65,000 years ago, during the last ice age. Arriving by sea, they settled the continent and had formed approximately 250 distinct language groups by the time of European settlement, maintaining some of the longest known continuing artistic and religious traditions in the world. Australia's written history commenced with the European maritime exploration of Australia. The Dutch navigator Willem Janszoon was the first known European to reach Australia, in 1606. In 1770, the British explorer James Cook mapped and claimed the east coast of Australia for Great Britain, and the First Fleet of British ships arrived at Sydney in 1788 to establish the penal colony of New South Wales. The European population grew in subsequent decades, and by the end of the 1850s gold rush, most of the continent had been explored by European settlers and an additional five self-governing British colonies established. Democratic parliaments were gradually established through the 19th century, culminating with a vote for the federation of the six colonies and foundation of the Commonwealth of Australia on 1 January 1901. Australia has since maintained a stable liberal democratic political system and wealthy market economy.
