Anglo Platinum - Operations (by Reef)

The Ore Reserve and Mineral Resource estimates were compiled in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves (The JORC Code, 2004) as a minimum standard. Where relevant, the estimates were also prepared in compliance with regional codes and requirements (e.g. The South African Code for Reporting of Mineral Resources and Mineral Reserves, The SAMREC Code, 2007). The Mineral Resources are additional to the Ore Reserves. Merensky and UG2 Reef Mineral Resources are reported over an economic and mineable cut appropriate to the specific reef. The mineable cuts collectively form the basis of the consolidated reef figures. Details of the individual operations appear in the Anglo Platinum Annual Report.

The figures reported represent 100% of the Mineral Resources and Ore Reserves attributable to Anglo Platinum Limited unless otherwise noted. Anglo American plc's interest in Anglo Platinum is 79.64%. Rounding of figures may cause computational discrepancies.

Tonnage: quoted as dry metric tonnes.

Grade: 4E PGE is the sum of platinum, palladium, rhodium and gold grades in grammes per tonne (g/t).
(3)
Merensky Reef and UG2 Reef: In 2008 Anglo Platinum sold its 22.4% share in Northam to Mvelapanda Resources. The associated Merensky Reef and UG2 Reef Ore Reserves have been excluded from the 2008 Ore Reserve figures (16.1Mt equivalent to 2.5Moz).
(4)
Merensky Reef: The reserve pay-limit varies across all operations between 2.3g/t and 5.7g/t. The variability is a function of various factors including the depth of the orebody, geological complexity and infrastructure.
(5)
Merensky Reef: Increase in Ore Reserves is mainly attributable to changes at Amandelbult due to a re-evaluation of the structural and geological model. The re-evaluation shows a reduction in the geological losses and a commensurate increase in the Normal Merensky Reef facies. These increased Mineral Resources have been converted into Ore Reserves.
(6)
UG2 Reef: The reserve pay-limit varies across all operations between 1.6g/t and 4.7g/t. The variability is a function of various factors including the depth of the orebody, geological complexity and infrastructure.
(7)
UG2 Reef: Increase in Ore Reserve tonnage is mainly attributable to Amandelbult and Rustenburg. At Amandelbult re-evaluation of the geological losses was undertaken and at Rustenburg a change in the modifying factors resulted in increased Ore Reserves.
(8)
UG2 Reef: Application for conversion to New Order Mining Rights for Modikwa Platinum Mine is in the process of being finalised and it is expected that the application will be lodged early March 2009. Modikwa Platinum Mine has until 30 April 2009 to lodge this application.
(9)
Platreef: The reserve cut-off is 1.7g/t for fresh ore and 3.0g/t for weathered/oxidised ore.
(10)
Platreef stockpiles: These are reported separately as Proved Ore Reserves and aggregated into the summation tabulations.
(11)
Alternative units: tonnage in million short tons (Mton) and grade in troy ounces per short ton (oz/ton).
(12)
Tailings: These are reported separately as Ore Reserves but are not aggregated in the total Ore Reserve figures. Operating tailings dams for current mining operations cannot be geologically assessed and therefore are not reported as part of the Ore Reserves. At Rustenburg Section historical dams have been evaluated and the tailings are included in the Ore Reserves statement.

Merensky Reef and UG2 Reef: In 2008 Anglo Platinum sold its 22.4% share in Northam to Mvelapanda Resources and expects to complete the sale of its 50% share in Booysendal in 2009. Consequently the Mineral Resources associated with Booysendal (Merensky Reef: 113Mt and 16.3Moz, UG2 Reef: 314Mt and 38.5Moz) and a component of Der Brochen (Merensky Reef: 24Mt and 3.7Moz, UG2 Reef: 31Mt and 4.9Moz) are excluded from the 2008 Mineral Resource figures.
