Mar 11, 2010 (A Wilson) - Radioactive quartz-pebble conglomerate lies directly on the basement granite. Narrow interbeds of argillite (greywacke) in the conglomerate are sometimes strongly radioactive. The best uranium mineralization occurs in the bedded argillite between conglomerate beds. The No. 1 Zone consists of a radioactive argillite bed 18 inches thick, striking S80E and dipping 55°N.

Dec 11, 2017 (A Wilson) - A 15.8 ft. section of core from Assembly DDH A-82 returned 0.056% U3O8. The uraninite is considered to be detrital in origin. Assays of the No. 2 Zone returned 0.48% U3O8 (chemical) and 0.05% ThO2 (chemical) and 0.065% U3O8. The No. 2 Zone consists of interbedded argillite and conglomerate. Samples assayed 0.08% U3O8.
