Apr 29, 2020 (Therese Pettigrew) - An occurrence of higher radioactivity was located on the southwest tip of Coveney Island, Sturgeon Lake. It occurs on the contact zone between the Sturgeon Lake syenite and the altered volcanic country rock. A small pit, 4-5 feet across and about 6 feet deep, has been sunk on a radioactive, highly altered, red-coloured contact phase of the syenite. This is a red feldspar rock containing purple fluorite, minor magnetite, traces of sulphides and an unidentified black mineral. Abundant secondary carbonate occurs in both the volcanic rocks and the syenite. Qualitative spectrographic analysis of a grab sample taken by the author from this pit gave: about 0.05 percent niobium; detectable amounts of thorium, cerium, and lanthanum; and 0.06 percent U3O8 equivalent (Rogers 1964). Four radioactive dykes were located on Coveney Island. The best assays were 0.15% U3O8 and 0.48% ThO2 (radiometric equivalent) and 0.015-0.020% Nb2O5 (radiometric equivalent) (Robertson and Gould, 1983).
