A copper mineral showing reported at Stony Islands was close enough to the 1973 field map area to be examined in the course if the Precambrian Shield fieldwork. Stony Island refers to a group of four islands within the Slave River and for ease of reference they have been designated - West, Mid, East and Tid Islands. A preliminary geological examination was carried out on West Island involving about half a day.
