Access Description: The property is located approximately 100 km from the town of Wawa, east of the town of Dubreuilville. Access to the property is via highway 17 west, to highway 519 (Dubreuilville Road) and then via the Goudreau Road for approximately 24 km. From the Edwards Gold Mine, follow road 49 east for approximately 3.5 km to a disused forestry road. Follow this road north east approximately 3 km to a barricaded road. The occurrence lies north of a pond approximately mid way along the road.

Dec 07, 2005 (A Wilson) - The occurrence lies within the Eastern Domain of the Goudreau Lake Deformation Zone. The GLDZ is up to 4.5 km in width and strikes in a gentle sigmoid-form for at least 30 km, subparallel to the stratigraphy and the regional foliation. In the immediate Goudreau-Lochalsh area, the GLDZ is coincident with a major contact between Cycle 2 and Cycle 3 volcanics. There is a strong structural control of the gold-bearing quartz veins systms within each of the 070-075 striking high-strain zones within the deformation zone. The Eastern Domain of the GLDZ is 9 km long and 2 km wide and contains narrow brittle and brittle-ductile high-strain zones displaying dextral, oblique slip displacement. Mineral lineations at the Cline Lake area have a consistent shallow plunge to the east and become moderately to steeply plunging in the Godin Lake area. Within the eastern domain, high-strain zones (as well as laminated, quartz-tourmaline and/or quartz-Fe-carbonate veins, fractures and flesic porphyry dikes) are dominantly parallel or at low angles to the east-striking regional foliation. The eastern domain is truncated on the west by the NW-trending Maskinonge Lake Fault.
