Resources
These resources are near surface, making them well-suited to low-cost open pit mining. And because most of the ore is gold oxide, it can be recovered relatively inexpensively.

Figures updated January 5, 2010 using 0.5 g/t cut-off with the exception of Bomboré which uses various cut-offs as indicated below.
1 Mineral Resources are not mineral reserves and do not have demonstrated economic viability. All figures have been rounded to reflect the relative accuracy of the estimates.
2 Mineral Resources constrained within a US$ 800 Whittle pit shell and above a cut-off of 0.24g /t for the oxide material, 0.25 g/t for the transition material and 0.52 g/t for the fresh material. Resource estimate performed by Orezone and audited by SRK Consulting (Canada) Inc. from Toronto, Canada, November 2008.
3 Mineral Resources outside a US$ 800 Whittle pit shell, but above a cut-off of 0.24 g/t for the oxide material, 0.25 g/t for the transition material and 0.52 g/t for the fresh material. Resource estimate performed by Orezone and audited by SRK Consulting (Canada) Inc. from Toronto, Canada.
4 Mineral Resources above a cut-off of 0.5 g/t. Resource estimate performed by Orezone and audited by Met-Chem Canada Inc. from Montreal, Canada, October 2007.
5 Mineral Resources above a cut-off of 0.5 g/t. Resource estimate performed by Orezone and audited by Met-Chem Canada Inc. from Montreal, Canada, March 2008.
