Notes to Table:
1. Figures in table may not add correctly due to rounding.
2. The resources are estimates of recoverable tonnes and grades using Multiple Indicator Kriging with block support correction.
3. Measured resources lie in areas where drilling is available at a nominal 25 x 25 metre spacing, Indicated resources occur in areas drilled at approximately 25 x 50 metre spacing and Inferred resources exist in areas of broader spaced drilling.
4. The resource model extends from 9700mN to 12200mN and to a maximum depth of 2mRL (a maximum depth of approximately 1050 metres below wadi level).
