Additional information | US Disclosure Port facilities The Pilbara Property’s mining assets are facilitated by port facilities in Dampier and Cape Lambert in Western Australia. These facilities include car dumping, conveying, stacking, reclaiming, screening and ship loading assets. One facility includes crushing and assets to handle crushed and deslimed ore from the Robe Valley operations. Stockyards allow for product management and blending to obtain the requisite specification requirement. There are seven operational wharf facilities with a total of 14 marine berths protected by berthing dolphins. Cape Lambert marine berths are capable of berthing vessels up to 280,000 deadweight tonnage. Further, Rio Tinto owns a fleet of tugs for the management of vessels during arrival and departure from the wharfs for the Pilbara Property.

Water supply systems at the Pilbara Property incorporate drinking water source protection plans, bores, pipelines, pumps and storage tanks and water treatment and disinfection assets. Wastewater from towns, mines, rail, ports and camps at the Pilbara Property is collected by the Rio Tinto managed sewerage systems and treated by onsite wastewater treatment facilities. Water supply and wastewater systems are regulated by Australian regulators (the Economic Regulation Authority, the Department of Water and Environmental Regulation and the Department of Mines, Industry Regulation and Safety).
