Feb 24, 2012 (A Wilson) - The pegmatite dike strikes N50E and has a width of 20-25 feet and extends for 175 feet along strike. The dike appears to be zoned into a white albite-quartz pegmatite wall zone and a pink microcline-quartz zone. Scapolitic pyroxenite also occurs in the vicinity of the dike.

Feb 24, 2012 (A Wilson) - A grab sample collected by the OGS (R-77-44-4) from the hornblende rich phase of the pegmatite assayed 8 ppm U3O8 and 608 ppm Th. A grab sample collected from a fracture in the pegmatite (R-77-44-2) assayed 10 ppm U3O8 and 1733 ppm Th. Sample R-77-44S-1 collected from a very hot spot on the pegmatite assayed 2500 ppm U3O8 and 5.2% Th.
