Dec 14, 2012 (A Wilson) - The metadiorite sill has a width of approximately 800 feet. North of the main sill, there is a complex of mafic metavolcanic flows and sill-like basic intrusion of gabbroic. Along the south contact, metadiorite is intensely chloritized and base metal mineralization occurs intermittently along it for approximately 8.05 km. The felsic metavolcanics south of the metadiorite consist of rhyolte breccia and tuff lenses. Four types of dikes are recognized in the mine area. They include lamprophyre, diorite, gabbro and diabase dikes. The diabase dikes are considered to be post-ore development.

Dec 14, 2012 (A Wilson) - Two types of ore are found to the south of the sill. The ore occurs as lenses of massive, high-grade chalcopyrite and in steeply dipping, fissure-filling quartz-carbonate, and chalcopyrite veins. Diamond drilling to the north of Island 725 by Abex Mines Ltd. returned 0.108% Cu, 0.24% Ni, 0.08% Co over 25ft in DDH 5; 1.01% Cu, 0.25% Ni over 36.2 ft in DDH 9 and 1.85% cu, 0.05% Ni and 0.025% Co over 6.25 ft in DDH 8. Assays from diamond drilling completed by Frontenac Exploration returned: 2.55% Cu, 0.49% Ni and 0.055% Co over 10 ft and 1.42% Cu, 0.36% Ni and 0.044% Co over 25 ft in DDH 77; 1.10% cu, 0.47% Ni and 0.061% Cu over 17 ft. and 1.00% Cu, 0.30% Ni and 0.060% Co over 29.5 ft in DDH 84. Three lenticular zones were identified during the drilling conducted in 1951-53. These zones occur on Timagami Island along the strike-faulted southern contact of the diorite sill. Zones 1 and 3 are separated by 600 feet.
