HOLLOW AUGER RESULTS


Assay results from the recently completed Hollow Auger (“HA”) drilling across the entire Mokobaesi.

Prospect are on average 47% higher grade than the factored (0.85 factor) radiometric probe grades that were used in the previous resource estimate (June 2008-SRK). Within the interpreted secondary ore zone (as modelled by Optiro using an approximate 50ppm U3O8 cut off grade) at Mokobaesi the HA grades are 17% higher than the factored probe grades.
