The uranium-molybdenum mineralization occurs in lenticular sandstone that cluster in three zones, defining a basal, main, and and upper mineral mineralised zone where containing > 60 ppm uranium (Cole and Wipplinger, 2001). The main zone contains uranium values of 802 to 7,716 ppm and molybdenum values of 55 to 871 ppm. The primary uranium ore minerals are coffinite and uraninite, and molybdenum in molybdenite.
