Point Location Description: Precise
Location Method: Conversion from MDI
Access Description: The prospect is located in claim K 919 on the eastern shore of Trafalgar Bay of Upper Manitou Lake, about 1.8 km south of Gold Rock community at the north end of Trafalgar Bay. It is 1.2 km WSW of the northern tip of Selby Lake and 40 km SSE of Dryden. (Historical File F07NE00010, SMDR#001418, Kenora Resident Geologist Office)
Selby Lake Mines Limited was organized in 1936 to develop a group of three claims that adjoin the Laurentian and the Big Master Mines to the south. The company was privately financed. Intensive surface work and diamond drilling had disclosed 11 quartz veins by the end of 1936. Work was concentrated on the extension of the Jubilee vein, and an ore shoot 2.7 metres wide and 97.0 metres long was reported to average 0.37 oz. Of gold per ton. In the autumn of 1937, a mining plant was installed and underground work begun. A two compartment shaft was sunk to 76.2 metres with levels at 125 ft. and 250 ft. Drifting was carried out on the 250 ft. level. /the results of this work was probably not encouraging since the mining plant was moved to the Big Master property in 1939. The assets of Selby Lake Mines Ltd., were taken over by Kenwest Gold Mines, Ltd., and operations thereafter were confined to the Big Master property.

Feb 24, 2010 (C Ravnaas) - Early Precambrian greenstones, contain horizons of porphyritic lavas which occur locally in the flows and may be traced for considerable distances along the strike. A narrow band of agglomerate and tuff occurs along the shore line of Upper Manitou Lake. The lavas have been intruded by felsite dykes. These rock assemblages belong to Superior Structural Province. A number of NE - striking quartz veins were found. They are mostly quartz lens located along zones of shearing in the volcanics. The main vein, near the lake shore on claim K 919, lies along a sheared zone that follows the contact between a felsite dike and metabasalt. The sheared zone was exposed in trenches for a distance of 135 m, attaining a width of 1.6 - 2.4 m. It contains quartz lenses and stringers banded by graphite and chlorite schist. The vein material ranges from a few cm to about 2.4 m. An ore shoot 2.7 m wide and 97 m long was reported to average 12.7 g/ t (0.37 oz/ton ) Au.
