Niobium and Phosphate products
estimates as at 31 December 2009
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 REPORTED AS ADDITIONAL TO 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.

Mining method: OP = Open Pit. LOM = Life of Mine in years based on scheduled Ore Reserves.
Due to the uncertainty that may be attached to some Inferred Mineral Resources, it cannot be assumed that all or part of an Inferred Mineral Resource will necessarily be upgraded to an Indicated or Measured Resource after continued exploration.
- (1)
- Catalão: Mineral Resources include 3.8 Mt oxide material and 47.6 Mt fresh rock and are reported above cut-offs of 0.50% Nb2O5 and 0.70% Nb2O5, respectively. Some 8 Mt of the Mineral Resources reported above are located on an adjacent mining concession that belongs to Fosfértil. An agreement for Mineração Catalão to mine this material is in place subject to royalty payments.

- Copebrás: Mineral Resources are quoted above a 7% P2O5 cut-off and with a CaO-P2O5 ratio between 1.0 and 1.4.
