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. Rock types in the stock are trachytic porphyritic syenites, melanocratic aegirine-rich syenites and a carbonate-rich mafic syenite cut by veins of pink syenite.
