Jan 28, 2020 (Therese Pettigrew) - In general, the main body of the Sturgeon Lake syenite registers 2-3 times the background radioactivity of the surrounding volcanic and sedimentary rocks. The outcrop areas of scapolite-rich syenite in the central part of the intrusion also register above background radioactivity (Rogers, 1964).

Jan 28, 2020 (Therese Pettigrew) - Two zones of higher radioactivity were observed on the northeast shore of the largest island in Sturgeon Narrows, northeast of Seaton Island. The zones are about 2-3 feet wide and are of unknown length. They consist of red, highly altered rock containing abundant carbonate, some hematite, surface staining, and minor amounts of tiny unidentified greenish-black, elongate ferromagnesian mineral(s). A sample from the Sturgeon Narrows zone assayed 0.01% U3O8 (radiometric equivalent) and 0.01% Nb2O5 (Rogers, 1964). DDH 89-2 encountered syenite and fenetized conglomerate with 3-8% disseminated pyrite and purple fluorite (Assessment report 52G15NW0002).
