Geology Comments

Sep 15, 2014 (Therese Pettigrew) - The Foisey property covers 2 km2 of the 39 km2 Kaby Lake stock within the SE sector of the stock. The Foisey system is a complex structural zone situated internally to the intrusive within 1.4 km of the intrusion’s SE contact zone. The 2008 drill program determined the Foisey Fault Structure to be an anomalous gold-bearing geologic feature along an 850 m strike length, open to the NW and SE, with a potential length in excess of 1.6 km. The structure was probed to an average vertical depth of 75 m (Hanych and Ewanchuk, 2010 AFRI 20000004782). The Hematite Shear is a separate structure 100 ft east of the Foisey Vein and has tested gold. The Central Vein is a 3-4 m wide quartz vein in a weakly sheared granite, in a strongly sheared, silicified hematite-pyrite alteration zone. The Central Vein is continuous for 1000 ft but no significant gold values have been returned from prospecting or trenching (Walker, 1990 AFRI 42E13SE0072). The property is almost exclusively underlain by granodiorite. This unit is a massive, equigranular, medium- to coarse-grained intrusive which usually contains 25-30% blue quartz grains. Fine-grained mafic dykes were often observed intruding the granodiorite and show a general 160-170° trend. The main showing is located within a 2-50 m wide ankerite alteration zone which contains varying amounts of pyrite mineralization. The alteration has widths of 5-30 m and was traced for a length of 1.1 km and may be open in either direction beneath overburden cover. Both the main ankerite-pyrite alteration zone and mafic dykes trend between 160-170°. A later cross-structure (possible faulting) trends between 120-140° (Bellinger, 1992 AFRI 42E13NE8333).

Mineralization Comments

Sep 15, 2014 (Therese Pettigrew) - 1933: An article in the Northern Miner reported gold values on the Foisey find of up to 0.45 opt and up to 15 ft wide. Burwash stated in the Canadian Mining Journal that samples from the Foisey occurrence, with 1.5 m widths gave values up to 0.23 opt. Grab samples where the fracture zone crosses a lamprophyre dyke returned 0.41 to 0.62 opt and channel samples yielded 0.16 to 0.26 opt. The vein was traced over an 850 ft length.1988: Channel samples of 0.566 oz/t Au over 0.44 m and 522-2178 ppb Au over 1.62 were collected. Grab samples had results of 6218 ppb and 7812 ppb Au over 0.3-0.4 m. Freewest collected channel samples that assayed up to 0.593 oz/t and grab samples that assayed up to 0.62 oz/t. 1989: Foisey vein returned a channel chip of 5.5 g Au over 2.0 m. Grab samples from the Foisey vein returned 19.36, 5.66 and numerous values in the 1-2 g/t Au range. 1991: Grab samples from the Foisey vein returned values of 20.86 g/t and 7.41 g/t Au. 2007: Mantis’ channel sample program had average Au values of 0.858 ppm along 8.97 m and 0.444 ppm along 6.23 m, with the highest value attained being 5.13 ppm. 2008: The 8 DDH program had the following results: FVS08-01: average Au value of 0.102 ppm. Between 77-82.49 m, values range from 0.263 to 1.305 ppm. FVS08-02: Gold values at 33.18 m and 139.0 m are 0.432 ppm and 0.567 ppm respectively. From 52.0-60.0 m, gold values are 0.181 ppm to 1.31 ppm with an average of 0.585 ppm. FVS08-03: 105.3 m – 0.797 ppm Au, 156.8-158.3 m, 166.5 m, 172.0 m and 174.35 m – gold levels are between 0.531 ppm and 1.225 ppm. FVS08-04: 155.5 m – 0.430 ppm Au. 180.5-185.0 m – 0.184 to 0.96 ppm Au. FVS08-05: 62.9 m – 3.29 ppm Au. 156.85 – 0.771 ppm Au. 157.85 m – 0.947 ppm Au.FVS08-06 : 37.0 m - 0.042 ppm Au. 77.3 m – 0.03 ppm Au. 81.5-85.5 m and 92.5 m – Au ranges from 0.059 to 0.105 ppm. FVS08-07 : from 85.35-86.26 m, Ag values in quartz vein stockworks are 0.538 to 0.557 ppm. 112.84 m – 0.603 ppm Au. 136.77-141.26 m – 0.553 to 1.05 ppm Au. FVS08-08: 40.5 m – 0.065 ppm Au. 153.0 m – 0.103 ppm Au. 158.99 m – 0.142 ppm Au.132.5 m – 0.119 ppm Au. Ag values range from 0.2 to 6.0 ppm in most holes and generally correlate with Au values. The mineralized system of the structure can be defined by two zones: an upper and lower, extending over an average of 80 m in drill width. The upper zone is defined by the fault structure of various alterations, namely hematite, sericite, and silica crushed rock-gouge of an earlier quartz vein phase. This zone is a strong structure that has been inundated by multiphase quartz veining. The average width of the upper zone is 42 m in drill width. The lower zone, with which the best gold values are associated, is characterized by intense silicification, in some cases manifest as massive grey quartz flooding. The grey clouding of the quartz is due to finely disseminated molybdenite. The average width of the lower zone is 5.55 m in drill width. Between the upper and lower zones is a variably silicified, hematized and quartz-veined quartz diorite averaging 32 m in drill width, containing 1-3% disseminated pyrite with anomalous gold values up to 0.298 g/t. The bedrock geology in the trenches reveals a complex, NW-trending (130° azimuth), 7-10 m wide zone of brittle deformation generated by a multi-phase quartz vein-silica stage that brecciated the host granodiorite. Within this zone, mafic inclusions, intense silicification, pervasive hematization and 1-3% disseminated pyrite occur. Gold mineralization is associated with ubiquitous, fine to medium-grained, anhedral to euhedral pyrite, with higher values where pyrite is concentrated in veins or along vein margins. Chalcopyrite and molybdenite mineralization are also present (Hanych and Ewanchuk, 2010 AFRI 20000004782).

Geologist: Robert Cundari

Notes: From OFR6302: The main Foisey occurrence was visited by staff of the Thunder Bay North Resident Geologist office in the fall of 2014. A 5 to 6 m wide by 45 m long northwest-striking stripped bedrock exposure was examined. The exposure consists of quartz stockwork and breccia, with veins averaging 0.5 to 4.0 cm wide in pink to red, hematite-altered, medium- to coarse-grained quartz diorite to granodiorite. In places, both the quartz vein material and granodiorite have been heavily recrystallized and sericitized. Mineralization generally consists of 1 to 2% disseminated, fine-grained subhedral to euhedral pyrite with the greatest amounts in areas of heaviest gossan. Samples collected by staff of the Thunder Bay North Resident Geologist office along the trend of the exposure returned values ranging from 317 ppb Au to 5.62 g/t Au.
