Access Description: The prospect lies approximately 3.2 km northeast of Ripple and 1.2 km south of McKellar Lake. It is approximately 29 km northwest of Marathon in Walsh Township (claim map G636, Walsh Township). Access may be gained using an old trail which extends about 2 km northeast from Highway 17 at a point near the McKellar Creek bridge. The showings are located just west of a small, unnamed lake. A quad-runner trail leads to the northwest from a small logging/mining road located 500 m west of Deadhorse Creek.
1873: Discovery of Little Pic Silver Mine; D. MacKellar. 1875: Stripping, trenching, shaft sinking (1.8 m by 3.3 m by 9.5 m deep), bulk sampling (1.81 t) and camp construction; D. MacKellar (?). The bulk sample was reported to have returned encouraging results but apparently no production ensued. 1952: Geological mapping, prospecting and sampling; Saratoga Exploration Company Limited. 1954: Diamond drilling (9 holes totalling 609.4 m); MacKellar Bay Mines Limited. 1965: Airborne geophysical survey (MAG, EM); Keevel Mining Group Limited. 1968: Geochemical soil survey; Halren Mines Limited. 1981: Ground geophysical survey (MAG, EM), geological mapping, lithogeochemical sampling and diamond drilling (1 hole, 161.2 m long); Canadian Nickel Company Limited. 1984: Compilation work, geological mapping and diamond drilling; J. Ternowsky. 1985: Property examination and lithogeochemical sampling; SH Resident Geologist staff (OGS). 1988-1990: Geological mapping, geochemical and geophysical surveys and diamond drilling were conducted in the vicinity of the Goldbar Lake, Marlhill and Prairie River (West) properties located to the west of the MacKellar Bay Mines Prospect; Noranda Exploration Company Ltd., Cumberland Resources Limited and Redfern Resources Limited. 1998: Major General Resources carried out linecutting and magnetometer survey. 2008: D. Michano, B. Gionet, J.G. Michano, and W. Michano staked the property and carried out prospecting. 2010-11: D. Michano, B. Gionet, J.G. Michano, and W. Michano carried out prospecting and sampling.

Dec 07, 2005 (D McKay) - Hinzer (1984, assessment files) describes the geology of the area as follows: The claim group lies within the eastern end of the Schreiber greenstone belt and is underlain by basic to felsic metavolcanic tuffs and metasediments. The rocks are strongly sheared in an east west direction and contain numerous north-south faults. The greenstone belt appears to be a steeply north to vertically dipping south facing homoclinal sequence. The Foxtrap-Glorylake batholith (1 km to the north) has strongly influenced the local structure and metamorphic grade. The stratigraphy is younging to the south, with sediments containing local iron formations capping a westward thickening volcanic pile. Numerous graphitic, ferruginous chert and sulphide iron formation allow good stratigraphic correlation. Numerous north bearing faults can be projected from both geological and geophysical data, many other minor faults are also indicated. Rapid lateral facies changes from east to west especially around Goldbar Lake are in part due to major north south faulting in this area. East of Goldbar Lake, a single mafic to felsic to sedimentary cycle is present on the property. West of Goldbar Lake two felsic to mafic cycles are present, and the felsic-sedimentary contact is interbedded with several iron formation zones. Folding is not readily observed. A major fold axis has been postulated passing through the north end of Goldbar lake centred on the quartz-sericite schists and several amphibolite zones. Perry (1982, assessment files) describes the nature of the MacKellar Bay zone as follows: A fracture or fault zone mineralized with pyrite, sphalerite and galena can be traced along a series of pits over a strike length of about 600 m near the northeastern part of the claim block. The fracture occurs within rhyolitic and dacitic tuffs. The mineralized zone is reported to vary in width from 2 to 15 feet.

Dec 07, 2005 (D McKay) - DeGagne (1989, assessment files) described the MacKellar Lake showings as associated with sulphidic iron formations and brecciated felsic tuff. Resident geologist staff observed sulphidic iron formation on both the south shore of Goldbar Lake and at the Michano Occurrences located approximately 1 km northeast of the MacKellar Bay property. The MacKellar Bay occurrence is considered to represent similar vein style mineralization to the Deadhorse Creek North and South occurrences, and may be related to the intrusion of the Coldwell Alkaline Complex to the east.

Dec 07, 2005 (D McKay) - The ore minerals consist of pyrite, sphalerite and galena. Native silver was reported by McKellar (1878?, Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay) DeGagne (1989, assessment files) stated that the mineralization consists of veined to massive galena and sphalerite. He reports the best historical results from the MacKellar Bay property as: 13.0% Zn, 7.14% Pb and 21.80 ounces per ton Ag across 4.5 feet at the shaft and 32.31% Zn, 1.14% Pb and 2.20 ounces per ton Ag across 3.5 feet from a trench. Bulk sampling by McKellar (1878?) returned high assays. Average values were approximately $125 silver and $50 to $60 lead to the ton of sorted ore (approximately 100 ounces per ton Ag, Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay). Grab samples collected from the occurrence in 1981 by Canadian Nickel Co. Ltd. returned assay results of up to 275 ppm Cu, 3.76% Pb, 8.92% Zn, 2.4 ounces/ton Ag and <5 ppb Au. Grab samples collected from the occurence in 1985 by OGS Resident Geologist staff returned assay results which varied from: <0.01 to <0.01 opt Au, 0.54 to 6.62 opt Ag, 1140 ppm to 13.4% Zn and 180 to 5160 ppm Pb.
