Inclusive of the Ore Reserve component.
(2)
It is anticipated that 8.7Moz of the South African Region’s published Mineral Resources will be taken up in stabilising pillars.
(3)
The Obuasi 2005 Ore Reserve is a major component of the Ghana total and is based on a Mineral Resource Model estimated in early 2005, using the techniques
against which the conversion factors between Mineral Resource and Ore Reserve have historically been determined. The Obuasi 2005 Mineral Resource was
estimated during the fourth quarter of 2005, using improved techniques. Consequently, the Modifying Factors between this in situ Mineral Resource and the ore
delivered to the mill have as yet not been quantified and are being determined by ongoing reconciliation.

Comments
The changes are due to a revised gold recovery model.
Increases due to exploration drilling were offset by the exclusion of WHEX due to leach pad capacity constraints.

Notes:
(1)
A range of cut-off grades indicates variable ore types.
(2)
Where no dilution factor is indicated the dilution is inherent in the resource model estimate.
(3)
A range of plant recoveries indicates variable ore types.
* Dilution: The difference between the tonnage broken in stopes and the tonnage milled from underground sources. For example, if 100 tonnes broken in the stopes amounts
to 132 tonnes milled, then the dilution is 32%.
** Mine Call Factor (MCF): The ratio expressed as a percentage, which the specific product accounted for in the recovery, plus residues, bears to the correponding product
called for by the mine's measuring methods.
