BHP Billiton Iron Ore, Western Australia Iron Ore site tour, 27 September 2011 Slide 2 Disclaimer Exploration results and mineral resources This presentation includes information on Exploration Results (Potential Mineralisation), Mineral Resources (inclusive of Ore Reserves) and Ore Reserves. The range of Potential Mineralisation is estimated from geological information including boreholes, outcrops and geophysical information, and is shown as a range (black bars). The potential quantity is conceptual in nature, there has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource. This data has been compiled by: P Whitehouse (MAusIMM) – Western Australian Iron Ore (WAIO). This is based on information in the BHP Billiton Annual Reports from 2007 to 2011 and other investor presentations which can be found at www.bhpbilliton.com, except for Potential Mineralisation figures for 2007, 2009 and 2011 which are reported here for the first time and are compiled by J Knight (MAIG) – WAIO.
