Exploration History

1983: Agassiz Resources carried out trenching and geological survey. 1984: Agassiz Resources carried out geophysical and lithogeochemical surveys. 1989: Western Troy Capital Resources staked the property and carried out geological and geophysical surveys. 1991: Western Troy Capital discovered the showing and carried out stripping, sampling, mapping, EM surveys, and drilled 3 DDH totalling 36.6 m. 1992: Western Troy Capital established a small gold mill on the property and commenced a 250-ton bulk sampling program. From 1992-94, Western Troy Capital processed approximately 1000 tons from the Wagg Prospect. 1994: Western Troy Capital drilled 6 short DDH. 2005: B.

Lithology

Lithology Comments

Dec 17, 2019 (Therese Pettigrew) - The Wagg prospect is situated within the Off-Burditt lakes greenstone belt and is underlain by medium- to fine-grained, mafic pillowed flows and massive coarse-grained flows. The mafic metavolcanic rocks contain narrow units of chert and tuffaceous interflow metasediments, and minor intermediate to felsic metavolcanic rocks. The metavolcanic rocks are intruded by numerous granitic, dioritic and pegmatitic dikes; small, felsic, porphyritic plugs; and diabase dikes. The Wagg prospect is about 400 m east of the contact between the metavolcanic rocks and granitic rocks of the Sabaskong Batholith. Host rocks are fine- to medium-grained, massive mafic flows and fine-grained, variolitic and hyaloclastic pillowed flows that are metamorphosed to upper greenschist facies. The rocks contain abundant biotite and epidote. The dominant structural fabric is a northeast-trending foliation. Wall rock alteration is minimal and consists of chloritization in sheared rock immediately adjacent to the quartz veins. Wall rocks may also contain up to 2% disseminated pyrite, pyrrhotite and chalcopyrite. Western Troy Capital reported that a silicified, quartz-stringer alteration zone occurs in pyritic, sheared wall rocks adjacent to the 'B' and 'D' veins. This alteration extends outwards, for about 0.5 m, from either side of the veins (Parker et al., 1993).

Mineralization

Mineralization Comments

Dec 17, 2019 (Therese Pettigrew) - Vein A is located at the most easterly point of the zone. Here a 0.5 to 1.75 m wide vein was uncovered for a length of about 13 meters. At the south end, the vein terminates into quartz stringers and at the north end the vein runs into a swamp. A 10 kg representative, composite sample from this vein averaged 0.939 ounces per ton gold. The arithmetic average of 7 samples taken in the quartz vein was 2.932 oz/ton. Grab samples from Vein A returned 0.064, 3.171, and 11.96 oz/t Au. Vein B was located about 10 meters west of Vein A. The vein here averages 0.5 m in width and was traced for about 13 m. At the north end the vein is cut by a porphyry intrusive and at the south end the vein runs into an area that was covered with mud and water. A 10 kg composite sample of the vein assayed 1.046 oz/ton gold. The arithmetic average of eleven samples taken in the quartz was 1.251 oz/ton. A channel sample from Vein A returned 2.848 oz/t Au over 1.0 m. A chip sample from Vein B returned 6.495 oz/t Au over 0.5 m. Vein C was located about 20 m west of Vein B. The vein averaged 0.45 to 0.75 m wide and was traced for a length of 12 m. At the north end the vein appears to be terminated by a bedrock lineament and at the south end the vein appears to terminate at the end of the outcrop. The arithmetic average of six samples taken in the quartz was 1.912 oz/ton. In Vein D, located about 15 m west of Vein C, the vein was 0.7 to 0.85 m wide and was traced for about 24 m. The vein appears to be open at both ends. A 10 kg composite sample from this vein averaged 1.406 oz/ton gold. At the east end of the trench a composite sample was made from 5 in-situ blocks of quartz covering a length of about 1.75 m and this sample assayed 0.345 oz/ton gold. The arithmetic average of sixteen samples taken in the quartz was 0.786 oz/ton. Vein E was located about 10 m north of the south end of Vein D and the quartz vein here varied from 0.8 to 0.9 m in width and was traced for a length of about 11 m. The vein appears to be open at both ends. A 10 kg composite sample from this vein averaged 2.045 oz/ton gold. The arithmetic average of ten samples taken from the quartz was 1.274 oz/ton. Vein F starts at about 20 m north of Vein B and extends for about 46 m north. The vein varies from 0.3 to 2.0 m wide and possibly connects with Vein E to the south and terminates at a porphyry intrusive to the north. A secondary offshoot vein parallels Vein F about 2 to 5 m southeast of Vein F. Assays from the offshoot vein were considerably lower than those from Vein F. A 10 kg composite sample from Vein F assayed 0.850 oz/ton. The arithmetic average of 23 samples taken from the quartz was 1.137 oz/ton. The veins are composed of fine to medium grained sugary quartz, and vary in colour from white to light brown to dark red. The veins tend to be fairly porous throughout, and vuggy sections are cannon. Mineralization consists of fine to occasionally coarse native gold, one to two percent fine pyrite,.lesser chalcopyrite often coated by covellite, and minute quantities of bornite, molybdenite and native copper. Hematite and limonite amount to one to two percent of the veins as stain and vug coatings. Black hematite crystals were observed at one location and traces of tourmaline have been observed within float vein material. A pinkish-white mineral that may be either a weathering product or a species of potassium feldspar was encountered with some regularity along fractures and the walls of sealed fissures. Gold is most abundant near and along vein walls, in and around vuggy portions of the veins, and in areas exhibiting some degree of structural complexity or strong iron staining. There appears to be little if any correlation between local sulphide abundance and gold content (Assessment report 52C13NW0015).

Dec 17, 2019 (Kristen Wiebe) - Sampling of the tailings pond material produced from treatment of approximately 907.18 tonnes of gold-bearing material resulted in an average gold content of 4.28 g/t from a total of 120 samples ranging from 1.008 g/t to 116.169 g/t Au (Assessment report 20000008962). Sample 32766 returned 24.002 ppm Au and sample 32770 returned 13.63 ppm Au (Assessment report 20000002087).
