This approximately circular stock some 3 km in diameter, is emplaced in Archaean volcanics, which are fenitized near the contact, and unconformably overlain by Aphebian sediments of the Montgomery Lake and Hurwitz Groups.

This circular magnetic anomaly is considered to be the signature of an alkaline complex. Hand specimens which unfortunately have not been described, are anomalously radioactive.
This is an ellipsoidal body of 7x2 km lying along the north shore of an arm of Kaminak Lake beneath which 35% of the complex lies. It is intruded between Archaean greenstones and tonalite, both of which are fenitized for up to 300 m from the contact.
