Nov 19, 2010 (A Wilson) - Ten widely spaced drill holes over an area 1,800 feet by 1100 feet indicated an average grade of 0.046% U3O8 over a width of 4.9 feet. The best intersections obtained by Algom Uranium Mines Ltd. returned 0.035% and 0.03% ThO2 over 1.3 feet and 0.025% and 0.035% ThO2 over 7.5 feet. Two deep holes drilled from the northeast side of the lake intersected 7 radioactive conglomerate bands. A 1.3 thick band at 1310.7 ft. contained 0.04% U3O8 and 0.03% ThO2. A 7.5 foot band at 1338.5 feet contained 0.03% U3O8 and up to 0.04% ThO2.
