Iron Ore: Kumba Iron Ore
The Ore Reserve and Mineral Resource estimates were compiled in accordance with The SAMREC Code, 2007. Rounding of figures may cause computational discrepancies. The Mineral Resources are reported as inclusive of those Mineral Resources modified to produce the Ore Reserve figures, i.e. the Ore Reserves are included in the Mineral Resource figures. The figures reported represent 100% of the Ore Reserves and Mineral Resources, the percentage attributable to Anglo American plc is stated separately.

Mining method: OP = Open Pit.
The tonnage is quoted as metric tonnes and abbreviated as Mt for million tonnes.
(1) Sishen Iron Ore Mine: New economic assumptions and revised Optimistic Pit shell applied.
(2) Thabazimbi Iron Ore Mine: New economic assumptions and revised Optimistic Pit shell applied.
(3) Sishen South Iron Ore Project – Ore Reserves: The process of converting Mineral Resources to Ore Reserves is time-consuming and as the geological model update was only completed late in 2007, the Ore Reserves reported are based on previous geological models. Globally the Mineral Resource estimates between the two models are similar with local variations which could impact the Ore Reserve estimates when updated in 2008.
(4) Sishen Iron Ore Mine – Outside Pit: Previously reported as ‘Underground’. Updated economic assumptions and a change in the long term outlook on exploitation of these resources resulted in the underground option no longer being considered.
(5) Thabazimbi Iron Ore Mine – Outside Pit: Previously reported as ‘Underground’. Updated economic assumptions and a change in the long term outlook on exploitation of these resources resulted in the underground option no longer being considered.
(6) Sishen South – Within Pit: Based on new geological models and a Mineral Resource update late in 2007.
(7) Sishen South – Outside Pit: Previously reported as ‘Underground’. Updated economic assumptions and a change in the long term outlook on exploitation of these resources resulted in the underground option no longer being considered.
