The Critter occurrence is located on a north facing slope of an east trending ridge, approximately 7 kilometres south-southeast of Johanson Lake (Property File - Canadian Superior Exploration Limited, Maps from Company Files, c. 1973).
The regional geology is similar to that of the Independence (094D 028) occurrence, which lies approximately 2 kilometres to the south-southeast.
The Critter occurrence lies near the contact between an unnamed Early Jurassic quartz diorite stock and Upper Triassic Takla Group volcanics. These rocks lie just to the east of the north striking Dortatelle fault. Mineralization consists of chalcopyrite and magnetite near a strong pyritic zone (Property File - Canadian Superior Exploration Limited, Maps from Company Files, c. 1973).
