Geology Comments

Feb 09, 2011 (C Ravnaas) - The property is underlain by a tonalite - trondhjemite northeast - southwest trending suite of the Bad Vermilion felsic intrusion. Narrow lenticular xenoliths of mafic and felsic metavolcanic flows are intercalated within the felsic intrusion. In the northeast part of the property under study, the felsic intrusion is in contact with the Bad Vermilion Lake mafic intrusion which is a highly differentiated anorthosite to gabbro suite.

Lithology Comments

Feb 09, 2011 (C Ravnaas) - This drilling defined a lens - shaped quartz vein within the McKenzie - Gray dextral shear zone. This shear zone is very strong, alteration and deformation can be observed up to 50 feet away from the shear. Usually gold bearing quartz veins form lenses along such shear zones. The vein is located within a highly sheared granodiorite in a NW trending fault/shear zone cross cutting the regional foliation. The vein is bounded by fractures and is boudinaged, folded vertically and horizontally, averages l metre in width and is exposed for 100 metres along strike.

May 28, 2019 (Therese Pettigrew) - The property is underlain by coarse-grained tonalite-trondhjemite and minor metagabbro. Metavolcanic xenoliths have been observed in the tonalite. Southwesterly- to northwesterly-striking shear zones host quartz veins (Poulsen, 2000).

Mineralization Comments

Feb 09, 2011 (C Ravnaas) - The lens dips approximately 15 degrees to the northwest along the shear zone plane. On surface, the vein has been trenched for a distance of more than 300 feet and the width of the vein varies from 0.5 to 3.5 feet. The vein has been intersected up to a depth of 200 feet where the width increases to 13 feet and defines a pencil - shape orebody. A tonnage of roughly 100,000 tons grading 0.30 opt Au (gold equivalent) has been estimated. Similar lenses can be expected all along the McKenzie - Gray shear zone. The McKenzie - Gray vein is the only vein containing gold - sulphide mineralization of economic concentrations. The quartz vein is reddish - grey with sericite - filled shear planes within the vein. It contains minor carbonate and tourmaline. Mineralization consists of free gold and gold within sulphides. The sulphides are black, brown and green sphalerite, chalcopyrite, galena and pyrite. The mineralization occurs along the total length of the veining anomalous and high grade sections.

May 28, 2019 (Therese Pettigrew) - The quartz veins contain appreciable amounts of sulphide minerals including pyrite, chalcopyrite and sphalerite. Malachite and calcite were also noted. Two principal systems are exposed on the property. The Main vein has been thoroughly channel sampled at various times on surface, and the following values have been reported: 0.49 oz/t Au over 2.9 feet (0.88 m) for 250 feet (76 m); 0.44 oz/t Au, 2.9 oz/t Ag over 4.0 feet (1.2 m) for 175 feet (53 m); 0.27 oz/t Au over 4.0 feet (1.2 m) for 300 feet (92 m); 0.47 oz/t Au over 3.56 feet (1.09 m) for 270 feet (82 m); and 0.49 oz/t Au over 4.6 feet (1.4 m) for 182 feet (56 m). A recent diamond-drill program revealed low gold values with the best reported intersection of 0.08 oz/t Au over 2.4 feet (0.73 m) of core. An earlier shallow diamond-drill program indicated 0.195 oz/t Au, 0.71 oz/t Ag, and 2.11% Zn over 2.36 feet (0.72 m) for a length of 220 feet (67 m) (Poulsen, 2000). The 25 ton bulk sample taken in 1984 was processed through a local mill. Available data indicates that the mill feed was graded at 7.2 g/t Au, 112.1 g/t Ag, 10-16% Zn, and 0.11% Pb. The 1200 ton bulk sample collected by Nipigon gold in 1990 returned metallurgical test samples with a grade of 5.66 g/t Au, 18 g/t Ag, 2.12% Zn, and 0.125% Cu (Assessment file 20000007340). Samples collected by OGS staff in 1980 recorded the following results: Sample 80LRC-12: 49.59 oz/t Au, 22.65 oz/t Ag, 0.25% Pb, 9.45% Zn, 4.20% Cu; Sample 80BCH-1: 1.46 oz/t Au, 5.80 oz/t Ag (Schnieders and Dutka, 1985).
