Anglo Base Metals - Nickel

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. The Mineral Resources are additional to the Ore Reserves.

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.

(1)
Barro Alto: Mineral Resources are quoted above a 0.9% Ni cut-off. An additional 0.42Mt of stockpiled ferruginous material with an estimated grade of 1.50% Ni containing 6,000 tonnes of nickel is available. Ore from Barro Alto is currently being processed at the Codemin plant. Inferred Mineral Resources external to the LOM comprise 21.8Mt with an average grade of 1.27% Ni, containing 275,000 tonnes of nickel.
(2)
Codemin: Mineral Resources are quoted above a 0.9% Ni cut-off.
(3)
Loma de Níquel: Mineral Resources are quoted above a 0.8% Ni cut-off (less than 35% Fe). Inferred Mineral Resources external to the LOM comprise 4.5Mt with an average grade of 1.50% Ni, containing 68,000 tonnes of nickel. Includes Ore Reserves and Mineral Resources in concessions cancelled by MIBAM, which Anglo American plc anticipates will be restored. Refer to note 37 (iii) to the financial statements for further information regarding these nickel exploration and exploitation concessions.
The Ore Reserves and Mineral Resources of Barro Alto, Codemin and Loma de Níquel will be reviewed during 2009 by independent consultants.
