Jan 27, 2017 (A Wilson) - Geiger readings on the bulldozed strippings were 1x-3x with spot-highs to 12x, and rarely, to 20x. The average is probably about 3x. At the 20x location a pale green diopside rock contains a few minute black grains of what is possibly uraninite-thorianite. On lot 30, concession 16,a syenite pegmatite outcrop has been further exposed by a bulldozed stripping. Geiger readings were 2x except on a fracture in the pyroxene syenite pegmatite giving a count greater than l00x. In this fracture a rusty filling, possibly 1 inch wide, consists of abundant zircon crystals, orange grains of uranothorite, yellow-to-orange kasolite, and pyrite. Four additional bulldozed strippings on this lot expose disintegrated marble with mica-rich bands and silicated marbles. Geiger readings were lx-3x, with spot-highs of 6x and oneof 30x on mica-rich areas. Turbid pink zircon (cyrtolite) crystals up to 5 mm long occur with black coffinite and orange uranothorite in pegmatite. Pink peristerite is a constituent of the pegmatite which contains green pyroxene, black amphibole, titanite, pyrrhotite and goethite. Yellow kasolite has been reported from the deposit.
