Dec 07, 2005 (C Salo) - Geological mapping (Wright 1922; Pyke 1976; Jensen and Baker 1986; Johnstone and Steele 1989; McClenaghan et al. 1988, 1987; Steele 1988) indicates that bedrock in the area consists mainly of weakly metamorphosed (greenschist or lower metamorphic grade except marginal to large felsic intrusive bodies, where amphibolite grade contact aureoles may be developed) subaqueously deposited volcanic rocks of the (Archean) Kinojevis Group and large felsic intrusive bodies.

Dec 07, 2005 (C Salo) - The discovery is near the Keewatin schist-granite contact. The main outcrop is near the centre of the four claims, and consists of Keewatin schists, hornblende and chlorite schist being the two prevailing types. The strike of the schist varies from east to west astronomic to north 35 degrees west. The dip is to the north and northeast at steep angles of 65 to 75 degrees. The Keewatin schists have been intimately intruded by narrow granite, some porphyritic, dikes. The dikes have no regular strike, but in a general way it is parallel to the schistosity of the Keewatin. In the main outcrop there is a sheeted zone slightly over 100 feet wide and exposed along the strike for several hundred feet. The schists in this zone strike north 37 degrees west, dip 65 degrees NE and are cut by a narrow quartz vein striking south 53 degrees east. The intervening rock and the quartz veins are slightly mineralized with cubical iron pyrites. The schists are locally altered to a ferruginous carbonate. There is a series of joint fissures at right angles to the main fracture. Grab samples, as nearly representative as possible, taken from sixteen different points across this sheeted zone, gave low gold values (p.21).
