Due to the complexity of drilling loose sands and gravels at surface with fine interstitial mineralization in the form of carnotite a specialized aircore rig was imported from Australia. This rig has commonly been used to drill similar style deposits in Australia and Africa. During the drilling of the majority of the holes reported herein, the loss of significant quantities of fine material was observed from the drill. At drill hole 46 modifications were made to the drills cyclone system to reduce loss of fines and 5 holes were selected for re-drilling. Overall the re-drills (see table below) with the cyclone modifications resulted in uranium grades higher than in the initial drilled holes.
