2005-11-1  The Cauê Formation, that hosts the iron ore reserves, consists of (oxide facies) banded iron formation formed by (1 mm to 1 cm thick) bands of iron oxides intercalated with bands (with similar thickness) of quartz and/or dolomite, named Itabirite in Brazil. The fresh rock (protore) averages 35 45% Fe. Its origin is sedimentary chemical.

Paper: Cockatoo Island: pit dewatering and wall

Abstract: The Cockatoo Island iron ore mine located in the Kimberley of Western Australia has had a history of instability related to critical seawall infrastructure over the last 15 years. This is in part due to the challenging setting of excavating an open pit directly adjacent to the sea. Seawall infrastructure has been constructed over thick very soft marine sediments to enable mining to
