Apr 11, 2014 (A Wilson) - On surface, the highest scintilometer readings were obtained where uranium oxide stain was observed in association with coarse biotite in the pegmatite dikes. Sexsmith (1958) also reports that 'assay results from selected (surface) samples (collected in 1957 prospecting) ranged from 0.02 to 0.87% U3O8.' The highest assay obtained in drill core from the Kassagimini Lake occurrence was 0.08 % U3O8. Assay results from selected samples ranged from 0.02 to 0.87% U3O8
