Notes:
- The mineral resources have been reported in accordance with the classification criteria of the South African Code for Reporting of Mineral Resources and Mineral Reserves (the SAMREC Code). SRK Consulting considers that the mineral resources estimate would be identical if reported in accordance with CIM standards.
- The mineral resource was estimated by Dr. Carina Lemmer of Geological & Geostatistical Services, an independent consultant, and reported to a cut-off of 30 cmkg/t U3O8 for Dominion and Rietkuil, and 0.00 g/tonne gold.
- Mineral resources are not mineral reserves and do not have demonstrated economic viability.
In addition, Uranium One has declared an Indicated uranium and gold resource for surface tailings material located on the Dominion property.

Notes:
- The mineral resources have been reported in accordance with the classification criteria of the South African Code for Reporting of Mineral Resources and Mineral Reserves (the SAMREC Code). SRK Consulting considers that the mineral resources estimate would be identical if reported in accordance with CIM standards.
- Mineral resources estimated by Mr. Charles Muller, B.Sc (Hons), Pr.Sci.Nat. of Global Geo Services (Pty) Ltd., an independent consultant. The surface tailings material is reported at a 0 cmkg/t cut-off and is inclusive of the entire surface tailings material, i.e. zero selectivity. Depletion of the mineral resource due to mining activities during 2007 has been calculated by Dr. Richard Stewart, PhD, Pr.Sci.Nat. of Uranium One.
- Mineral resources are not mineral reserves and do not have demonstrated economic viability.
