ORE RESERVES AND MINERAL RESOURCESCOALestimates as at 31 December 2012METALLURGICAL COALThe Coal Reserve and Coal Resource estimates were compiled in accordance with the Australasian Code for Reporting of Exploration Results,Mineral Resources and Ore Reserves (The JORC Code, 2004) as a minimum standard. The figures reported represent 100% of the Coal Reserves andCoal Resources, the percentage attributable to Anglo American plc is stated separately. Rounding of figures may cause computational discrepancies.Anglo American Metallurgical Coal comprises export metallurgical and thermal coal operations located in Australia and Canada.Metallurgical Coal – Australia OperationsROM Tonnes (3) Yield (4) Saleable Tonnes (3) Saleable QualityMineCOAL RESERVES (1) (2)Attributable % Life Classification 2012 2011 2012 2011 2012 2011 2012 2011Callide (OC) 100 24 Mt Mt ROM % ROM % Mt Mt kcal/kg kcal/kgThermal – Domestic Proved 192.2 199.9 97.9 98.0 188.2 195.8 4,380 4,380Probable 52.0 52.0 98.0 98.0 51.0 51.0 4,250 4,250Total 244.2 251.9 97.9 98.0 239.2 246.8 4,350 4,350Capcoal (OC) 76.8 23 CSN CSNMetallurgical – Coking Proved 69.9 77.1 19.8 20.4 14.4 16.3 7.0 7.0Probable 72.5 72.5 16.4 16.4 12.3 12.3 6.5 6.5Total 142.4 149.5 18.0 18.5 26.7 28.6 7.0 7.0kcal/kg kcal/kgMetallurgical – Other Proved 46.3 46.3 33.6 37.0 6,970 6,970Probable 46.5 46.5 35.0 35.0 6,990 6,990Total 46.4 46.4 68.7 72.1 6,980 6,980kcal/kg kcal/kgThermal – Export Proved 2.7 2.8 2.0 2.3 7,070 7,060Probable 2.3 2.3 1.7 1.7 7,030 7,030Total 2.5 2.6 3.7 4.0 7,050 7,050Capcoal (UG) 70.0 11 CSN CSNMetallurgical – Coking Proved 36.0 40.6 75.1 73.7 28.5 31.6 9.0 9.0Probable 14.7 14.7 72.0 72.0 11.2 11.2 9.0 9.0Total 50.7 55.3 74.2 73.2 39.7 42.7 9.0 9.0Dawson (OC) 51.0 35 CSN CSNMetallurgical – Coking Proved 180.7 15.0 24.0 19.9 44.7 3.1 7.5 7.5Probable 227.2 149.0 21.0 16.0 49.1 24.5 7.5 7.5Total 407.9 163.9 22.4 16.4 93.8 27.5 7.5 7.5kcal/kg kcal/kgThermal – Export Proved 51.6 65.2 95.8 10.0 5,440 6,500Probable 53.6 59.4 125.3 90.9 5,340 6,500Total 52.7 59.9 221.1 101.0 5,380 6,500Drayton (OC) 88.2 2 kcal/kg kcal/kgThermal – Export Proved 7.9 3.2 76.0 75.3 6.0 2.4 6,650 6,260Probable 4.2 19.7 76.0 75.6 3.2 14.9 6,600 6,260Total 12.0 22.9 76.0 75.6 9.2 17.3 6,630 6,260Foxleigh (OC) 70.0 3 kcal/kg kcal/kgMetallurgical – Other Proved 1.9 4.1 83.0 79.3 1.7 3.5 6,870 6,940Probable 12.6 13.7 77.7 77.2 10.4 11.3 6,800 6,810Total 14.5 17.8 78.4 77.7 12.1 14.8 6,810 6,840Moranbah North (UG) 88.0 17 CSN CSNMetallurgical – Coking Proved 109.5 114.8 76.6 76.4 88.5 92.6 8.0 8.0Probable 11.3 11.3 72.7 72.7 8.7 8.7 8.0 8.0Total 120.8 126.1 76.2 76.1 97.2 101.3 8.0 8.0Australia Metallurgical – Coking 70.6 Mt Mt Plant % Plant % Mt Mt CSN CSNProved 598.0 454.6 58.4 68.2 176.0 143.5 8.0 8.0Probable 394.4 332.8 32.9 35.8 81.3 56.6 7.5 7.5Total 992.5 787.4 50.3 59.0 257.3 200.1 8.0 8.0Australia Metallurgical – Other 75.8 kcal/kg kcal/kgProved 48.1 49.1 35.3 40.5 6,970 6,970Probable 53.7 54.0 45.5 46.3 6,940 6,940Total 51.2 51.7 80.8 86.8 6,950 6,960Australia Thermal – Export 52.9 kcal/kg kcal/kgProved 52.0 57.3 103.8 14.7 5,540 6,550Probable 53.5 60.7 130.2 107.5 5,390 6,480Total 52.9 60.3 233.9 122.2 5,460 6,480Australia Thermal – Domestic 100 kcal/kg kcal/kgProved 97.9 98.0 188.2 195.8 4,380 4,380Probable 98.0 98.0 51.0 51.0 4,250 4,250Total 97.9 98.0 239.2 246.8 4,350 4,350Metallurgical Coal – Canada OperationsROM Tonnes (3) Yield (4) Saleable Tonnes (3) Saleable QualityMineCOAL RESERVES (1) (2)Attributable % Life Classification 2012 2011 2012 2011 2012 2011 2012 2011Trend (OC) 100 10 Mt Mt ROM % ROM % Mt Mt CSN CSNMetallurgical – Coking Proved 17.9 20.3 66.3 65.0 12.4 13.9 7.0 7.0Probable 2.3 2.3 61.7 61.7 1.5 1.5 7.0 7.0Total 20.2 22.6 65.8 64.7 14.0 15.4 7.0 7.0kcal/kg kcal/kgThermal – Export Proved 0.7 0.7 0.1 0.1 5,070 5,070Probable 0.8 1.1 0.0 0.0 5,070 5,070Total 0.7 0.7 0.2 0.2 5,070 5,070Mining method: OC = Open Cut, UG = Underground. Mine Life = The extraction period in years for scheduled Ore Reserves comprising Proved and Probable Reserves only.For the multi-product operations, the ROM tonnes 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.Metallurgical – Coking refers to a high-, medium- or low-volatile semi-soft, soft or hard coking coal primarily for blending and use in the steel industry; quality measured as Crucible Swell Number (CSN).Metallurgical – Other refers to semi-soft, soft, hard, semi-hard or anthracite coal, other than Coking Coal, such as pulverized coal injection (PCI) or other general metallurgical coal for the export ordomestic market with a wider range of properties than Coking Coal; quality measured by calorific value (CV).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).200 Anglo American plc Annual Report 2012(5)(5)
