Mine Life = The extraction period in years for scheduled Ore Reserves comprising Proved and Probable Reserves only.For the multi-product operations, the ROM tonnage figures apply to each product.The Saleable tonnes cannot be calculated directly from the ROM reserve tonnes using the air dried yields as presented since the difference in moisture content is not taken into account.Attributable percentages for country totals are weighted by Saleable tonnes and should not be directly applied to the ROM tonnes.Footnotes appear at the end of the section.Thermal – Export refers to low- to high-volatile thermal coal primarily for export in the use of power generation; quality measured by calorific value (CV).Thermal – Domestic refers to low- to high-volatile thermal coal primarily for domestic consumption for power generation; quality measured by calorific value (CV).Synfuel refers to a coal specifically for the domestic production of synthetic fuel and chemicals; quality measured by calorific value (CV).Ore Reserves and Mineral ResourcesAnglo American plc Annual Report 2012 205
