Lithology Comments

Jan 27, 2017 (A Wilson) - The main showing at the north side of the small lake is an exposure of medium-grained pale-green diopside rock about 50 ft. long and 15 ft. wide. Patches of mica are present. Fracture planes are coated with scattered grains of titanite and more rarely, uraninite. The diopside rock is cut by veins of white albite and one fissure vein of salmon-pink calcite in which the wall s are lined with albite and mica.

Mineralization Comments

Jan 27, 2017 (A Wilson) - Geiger counter readings were 4x-10x with occasional spot-highs on uraninite grains. The shallow holes below this exposure cut diopside rock with high radioactivity over widths of 1-2 feet at depths up to 25 feet. Radioactivity in pegmatites is of secondary interest due to a high thorium to uranium ratio.
