Point Location Description: Shaft

Location Method: Data Compilation

Access Description: Access is via Highway 11, then north at its junction with Highway 623 to the setlement of Sapawe on the southern shore of Sapawe Lake. The old Walsh shaft is due north from here, across Sapawe Lake and 400m north from the northern shore of Sapawe Lake.

Exploration History

1901: A shaft was sunk on Mining Location BJ118 to a depth 40 feet by J.J. Walsh. 1907: Shaft sunk to 50 feet, 18 tons milled. 1928: the Jackson Syndicated dewatered the shaft, and carried out considerable trenching, stripping and sampling 1930-34: Worked by Central Canada Mines, shaft continued to 92 feet. Installation of 25 ton amalgamation mill. Minor tonnage milled. Drilled 18 DDH totalling 1829 m. 1966-67: Anjamin Mines Limited completed 8 diamond drill holes for 583 m of drilling on claim FF15090. On claim FF15092, adjacent east of FF15090, 8 drill holes were completed with 442m. of diamond drilling. Trenching was also preformed during this time. 1984: Kenergy Resources Corp. optioned the property and carried out line cutting, geological mapping, prospecting, sampling, and ground geophysical survyes. 1985: Interquest Resources drilled 13 DDH. 2001-02: OGS staff carried out sampling. 2004: Freewest Resources Canada optioned the property and carried out stripping and sampling. 2009: TerraX carried out prospecting, sampling, and reprocessing airborne magnetic data. 2010: TerraX conducted resistivity, IP, and magnetics surveys, and sampling. 2012: TerraX drilled 3 DDH totalling 363.04 m.

Lithology

Lithology Comments

Jul 31, 2020 (Therese Pettigrew) - The general geology consists of basalt, chlorite schist and gabbro which have been intruded by felsic intrusive rocks, including quartz porphyry and aplite. The area is situated less than 1 km north of the Quetico Fault, a major east-trending regional structure. The general geology consists of basalt, chlorite schist and gabbro which have been intruded by felsic intrusive rocks, including quartz porphyry and aplite. The area is situated less than 1 km north of the Quetico Fault, a major east-trending regional structure. The quartz veins display crack-seal to ribbon textures, with abundant tourmaline, pyrite, chalcopyrite and arsenopyrite (Schnieders et al., 2003).

Mineralization

Mineralization Comments

Jul 31, 2020 (Therese Pettigrew) - Gold mineralization is hosted by quartz-tourmaline veins, within sheared, deformed, carbonatized and sericitized quartz porphyry. Historical reports indicated up to 7 parallel and extensional quartz vein sets over a strike length of 1000 m and across a width of 400 m. A grab sample of vein material was collected by OGS staff member J. Scott returned up to 0.44 oz/t Au (15.1 g/t Au) (Schnieders et al., 2003)..Gold mineralization is associated with east-northeast-trending quartz-iron carbonate veins with minor pyrite and local tourmaline and/or arsenopyrite. These veins are more common in or close to porphyry bodies than in the mafic rocks, and have locally been folded and dismembered. TerraX samples all had detectable gold, and seven samples had >250 ppb Au. This includes results of 2.8, 4.48, and 22.9 g/t Au. In November 2010, TerraX collected 123 channel samples. The highest channel sample was 0.45 m @ 7.5 g/t Au, west of the shaft in an area were previous grab sampling returned up to 39.6 g/t Au. The outcrop west of the shaft had three closely spaced, highly anomalous sets of channel samples from the same channel, namely: 12 m @ 334 ppb Au, 2.0 m @ 2510 ppb Au, and 6.2 m @ 325 ppb Au. The outcrop south of the shaft had a chain of samples which collectively ran 2.65 m @ 754 ppb Au. DDH CC12-01 returned 1.32 g/t Au over 10.61 m including 4.77 g/t Au over 1.82 m. DDH CC12-02 returned up to 1.35 g/t Au over 1.92 m. DDH CC12-03 returned 0.83 g/t Au over 23.30 m including 7.36 g/t Au over 0.63 m and 4.44 g/t au over 1.86 m (Assessment report 20000009230).
