Kumba Iron Ore

The Ore Reserve and Mineral Resource estimates were compiled in accordance with The SAMREC Code, 2007. The Mineral Resources are reported as exclusive of those Mineral Resources modified to produce the Ore Reserve figures, i.e. the Ore Reserves are excluded from the Mineral Resource figures. In contrast, in 2007, Anglo American reported Mineral Resources for Kumba Iron Ore inclusive of Ore Reserves. The change to an exclusive reporting basis is in alignment with Anglo American’s reporting practice. These exclusive Mineral Resources are taken from the Kumba Iron Ore Annual Report of 2007.

The figures reported represent 100% of the Ore Reserves and Mineral Resources, the percentage attributable to Anglo American plc is stated separately. Rounding of figures may cause computational discrepancies.

Mining method: OP = Open Pit.
The tonnage is quoted as dry metric tonnes and abbreviated as Mt for million tonnes.
Kumba Iron Ore delimit resources within an economic shell based on double the Free On Rail forward-looking long-term iron ore price.
The Mineral Resources in addition to those considered for the Life of Mine (LOM) are reported as Outside Pit.
The Zandrivierspoort Project is no longer reported as Anglo American’s shareholding (23.3%) is below the internal threshold for reporting. Details of this project are presented in the Kumba Iron Ore Annual Report.
(1)
Sishen Iron Ore Mine – Ore Reserves: Decrease is predominantly reflective of production with a lesser contribution from changes to the geological model.
(2)
Sishen South Iron Ore Project – Ore Reserves: Increase is attributable to an updated geological model, changes in economic assumptions including the increased forward-looking Free On Rail iron-ore price and a reduced cut-off grade.
(3)
Sishen Iron Ore Mine – Outside Pit: Increase is due to revision of geological model based on exploration drilling and the increased forward-looking Free On Rail iron-ore price.
(4)
Sishen South Iron Ore Project – Within Pit: Increase is mainly a response to the increased forward-looking Free On Rail iron-ore price.
The Mineral Resources of the following operations were reviewed during 2008 by independent consultants: Sishen Iron Ore Mine.
