1. Type of mine: O/P = open pit/surface. 2. Mineral Reserves of iron ore are shown as recoverable Mineral Reserves of marketable product after accounting for all mining and processing losses. Mill recoveries are therefore not shown. 3. Iron ore Mineral Reserves valuations are based on Rio Tinto’s assessment of the various product premiums which are added to consensus pricing for 62% iron fines. This consensus is the average of long-term forecasts from eleven brokers/banks (Barclays, BMO, BoAML, Citigroup, Deutsche Bank, Goldman Sachs, HSBC, JP Morgan, Macquarie, Morgan Stanley and UBS) and two analysts (CRU and Woodmac) and is USc131/dmtu CFR China. The premiums are estimated by Rio Tinto’s value-in-use models that calculate steelmaking cost savings or benefits arising from differences in product specifications relative to the 62 iron fines index. 4. Australian iron ore Mineral Reserves tonnes are reported on a dry weight basis. 5. Australian iron ore Mineral Reserves are all located on State Agreement mining leases. Prior to mining, state government approvals (including environmental and heritage) are required. Reported Mineral Reserves include select areas where one or more approvals remain outstanding. In these areas, it is expected that these approvals will be obtained within the time frames required in the current production schedule. 6. Australian iron ore deposits (Total Australia) are the equivalent of the Pilbara Property for this Form 20-F . 7. Iron Ore Company of Canada (IOC) Mineral Reserves are reported as marketable product (61% pellets and 39% concentrate for sale) at a natural moisture content of 2%. The marketable product is derived from mined material comprising 208 million dry tonnes at 39% iron, 34% silica, 0.20% alumina, 0.022% phosphorus (Proven) and 358 million dry tonnes at 39% iron, 34% silica, 0.19% alumina, 0.022% phosphorus (Probable) using process recovery factors derived from current IOC concentrating and pellet
