Dec 07, 2005 (R Degagne) - Red syenite dikes, believed to be related to a plug of red syenite several miles long and about one-half mile wide, which occurs on the west contact of a large augite syenite intrusive, range in size from a few inches to thirty or more feet. These dikes are radioactive and are columbium bearing. The dikes have penetrated along well defined north-south and east-west fractures and appear to form a fairly continuous pattern in the Port Munro area. The zone extends southward for at least two miles along the west side of the syenite plug. (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay).
