Lithology Comments

Aug 29, 2019 (Sheree Hinz) - The area comprises a basin-shaped remnant of deformed Huronian sedimentary rocks lying unconformably on a granite basement complex. The Mississagi Formation consists of quartzite, arkose, with argillite partings and scattered thin interbedded pyritic quartz-pebble conglomerate. Radioactivity increases towards basement contact.




Mineralization Comments

Aug 29, 2019 (Sheree Hinz) - In trenches the following assays were obtained: 0.027% U3O2, 0.038% U3O2. In the initial drill hole in 1957 the following assays were obtained: 0.044% U3O8 over 1 foot, 0.042% U3O8 over 3.5 feet, 0.032% U3O8 over 2 feet. In the follow-up drill program in 1958, all assays were less than the previously stated and the property lapsed.
