Point Location Description: Drill collars in SW SSM 1174694
Location Method: Data Compilation
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. Walk approximately 200 m up the hill to the open pit and then up the old drill road for another 200 m. The zone is defined by a line of drill collars.

Metamorphism Grade: Greenschist
Nov 16, 2010 (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 systems 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 felsic 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.

Nov 16, 2010 (A Wilson) - The zone lies within intensely sheared mafic metavolcanics which lie on either side of a feldspar porphyry dike. Gold values occur along the contacts of both units within an intensely sheared quartz-carbonate schist. This zone is roughly coincident with one of the zones defined on the adjacent Cline Mine property. Three shear zones have been identified and traced over a distance of 800 m. The shear strikes approximately east-west and dips 75-85° N.

Nov 16, 2010 (A Wilson) - Assays from Pele's 1997 drilling returned values of 4.2 g/t Au over 0.3 m, 2.23 g/t Au over 0.66 m, 4.97 g/t Au over 0.37 m, 1.334 g/t Au over 0.4 m and 3.184 g/t Au over 0.63 m. Surface grab samples as high as 17.76 g/t Au over 0.3 m and 12.75 g/t Au over 2.64 m have been reported by Pele Mountain Resources.
