Hosted in Aquifer– Drillers report water intersections in running sands
– Samples lifted by Air Core drilling
– Higher grades report to sand/mud contact (e.g. Beverley)
Hydrogeological confinement– Consistent intersections of the lower T mudstone
– Drillers report pressurized aquifers
Typical Mineralogy– Anatase, uraninite, pyrite & LREE enriched hydrated phosphates
Evidence of variable disequilibrium– Up-to 5x in TNG006MD
Low salinities– TDS ~2000mg/L in air-lifted water samples
Low carbonate– Average = 0.15% Ca from diamond core of channel & mud facies
Forward Exploration Program
Focus on Tertiary Hosted Uranium– Reconnaissance Rotary Mud Program & gamma/resistivity
– 800m & 1600m spacing within interpreted paleo-valleys– Drill along EM lines– Map oxidation fronts– Understand Tertiary facies distribution
