Exploration History

1934: Discovered by the Powell Brothers of Saganaga Lake, minor trenching was conducted. 1956: The Consolidated Mining and Smelting Company of Canada Limited conducted trenching and drilled 3 DDH. 1965: Area mapped by F. R. Harris for the Ontario Department of Mines. 1971: Dome flew an airborne geophysical survey. Addicks Canadian Properties Inc. flew an EM survey. 1984-5: Curran Bay Resources drilled 23 DDH totalling 1212 m (20 holes on the Powell showing and 3 holes on the East Beaverpond showing) and conducted line cutting, VLF-EM and magnetometer geophysical surveys, geological mapping, trenching and sampling. 1987: Wye Resources optioned the property from Curran Bay and conducted trenching and sampling. 1988: Wye did line cutting, IP and magnetometer surveys, geological mapping, and drilled 23 DDH totalling 1850 m. 1991: Wye conducted 360 m of drilling on the Powell and Starr zones. 1992: Wing Resources Inc. conducted geological mapping, VLF-EM and ground magnetometery surveys, and drilled 3 DDH totalling 61 m on the Starr Zone, 2 DDH totalling 95 m on the East Beaverpond showing and 1 DDH totalling 69 m west of the Starr Zone. 1993: Wing Resources and Wye Resources drilled 2 DDH totalling 91 m in the Starr Zone. 1995: Wye Resources conducted stripping, sampling, mapping and drilled 10 DDH totalling 360.5 m on the Powell and Starr zones. 2005: Benton Resources Corp. entered into an option agreement with Wing Resources to gain a 100% in the property. Benton conducted grid cutting, mapping, trenching, sampling, IP and ground magnetic surveys. 2006: Teck Cominco Ltd. optioned the property from Benton Resources. 2007: Teck Cominco conducted a humus geochemical survey, geological mapping, airborne geophysical surveys, and a diamond drill program. 2008: Benton Resources conducted mapping, trenching and sampling. 2010: Benton Resources conducted geophysical surveys. 2012: Benton Resources drilled 16 DDH totalling 2654 m. 2020-22: Metallica Metals optioned the property from Benton Resources and conducted airborne magnetometer and electromagnetic geophysical surveys, prospecting, sampling, and drilled 30 DDH totalling 4426 m including 6 DDH totalling 684 m on the Powell showing.

Lithology

Lithology Comments

Jun 23, 2023 (Therese Pettigrew) - The main lithology encountered the six holes drilled at the Powell zone was mafic volcanic. This unit was generally fine grained, massive to weakly foliated locally, with randomly oriented quartz stringers up to 2 mm in thickness throughout. These stringers are often discontinuous and are not found to be associated with any sulphide mineralization. Localized zones of epidote alteration and hematite alteration are observed. Of the six holes drilled in 2021, three of them intersected the Powell vein; STR21-009, 010, and 011. Occurring at an average depth of 85 meters, the drilled width of the Powell vein ranged from 0.5 to 2 meters and had a near vertical dip. Visually the Powell vein was commonly brecciated leading to a “stock-work like” appearance with local intervals of moderate to intense chlorite banding. Quartz feldspar porphyry dykes were observed cutting the mafic volcanics in all the holes at the Powell zone. This unit has coarse grained feldspar phenocrysts and lesser amounts of quartz (blue) phenocrysts. A fine-grained gray matrix surrounding the phenocrysts was found to occasionally contain trace amounts of disseminated pyrite (Pettigrew, 2022).

Mineralization

Mineralization Comments

Aug 28, 2015 (Therese Pettigrew) - A quartz vein striking 40-55 degrees varying in width from 0.9-6 m is exposed along strike for up to a length of 121 m. The vein is hosted by massive metavolcanics with associated felsic porphyritic intrusions. Mineralization consists of pyrite and chalcopyrite. A major NE-trending fault is located several hundred metres south of the occurrence. Reported sampling results from 1956 range from 3.48 g/t Au over 0.15 m to 8.9 g/t Au over 0.5 m (Harris, 1968). The best samples from the Curran Resources drill program in 1985 assayed 0.83 oz/t over 9.3 ft, 0.77 oz/t over 4.9 ft and 0.55 oz/t over 2.3 ft. According to Kretschmar (1988, AFRI 52B07SW0012), at the Powell Showing there are 3 main ore-bearing horizons and several others that have been drilled over a strike length of 100 m. Boudinaged gold-bearing quaitz-carbonate, pyrite, chalcopyrite veins occur in a 20 m wide structure in pillowed andesites and tuffs. The ore occurs in shoots with unknown rake. Drilling extended the mineralization to a maximum depth of 75 m. The best assay was 2.95 m true width, averaging 32.77 g/T from a high grade lens. Gold-bearing quartz veins occur in a stratigraphic package consisting of fine-grained green andesitic tuffs, black chloritic tuff or chlorite alteration, pyrite, white and pink carbonate, minor jaspery silica alteration, hematite, magnetite, and a cherty siliceous unit that may be chert or may represent silica flooding (e.g. 88-13, about 43 meters). This ore-bearing stratigraphic package (or structure) is contained in massive and pillowed flows of similar composition (AFRI 52B07SW0012). DDH STR21-10 returned 0.53 g/t Au over 42.5 m including 2.01 g/t Au over 8.35 m (Pettigrew, 2022).
