Mineral Resources are inclusive of Mineral Reserves. All tonnes relate to metric units. Rounding-off of figures may result in minor computational discrepancies – where this happens it is not deemed significant.
In Australia (Agnew and St Ives), a gold price of A$1,650 and A$1,500 was used to determine the Mineral Resources and Mineral Reserves respectively. Mineral Resources for the South Africa region was determined at R420,000/kg, while the Mineral Reserves was determined at R380,000/kg.
In South America (Cerro Corona) and West Africa (Damang and Tarkwa), the Mineral Resources and Mineral Reserves were determined using a gold price of US$1,650/oz and US$1,500/oz, and a copper price of US$3.90/lb and US$3.50/lb respectively.
Growth projects are reported independently under the Growing Gold Fields section on p112 – 119 of the report.

3 The BBBEE transaction concluded in December 2010 grants an empowerment consortium 10% of South Deep. Based on the relevant sliding scale of the vesting of the economic benefit attached to the 10%, and the current LoM profile, the Mineral Resources and Mineral Reserves portion attributable to Gold Fields is 92.1%
