Point Location Description: Old pits on quartz veins
Location Method: Other Literature
Access Description: Access is via an 18 km all-weather gravel road that turns off of highway 519 just west of the town of Dubreuilville. Dubreuilville is on highway 519, 44 km east of the junction of Highway 17 and 519. The occurrence is located on the south east side of Maskinonge Lake and is most easily accessed by following the water intake road from the Kremzar mill to Maskinonge Lake.
1930's: Michael Syndicate - stripping, trenching. 1985: Ferderber Geophysics - airborne geophysical survey.

Metamorphism Type: Regional
Metamorphism Grade: Greenschist
Dec 07, 2005 (A Wilson) - The deposit lies within the Northern 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 Northern Domain of the GLDZ is located immediately south of the Maskinonge Lake stock and is composed of brittle to brittle-ductile high-strain zones oriented at high angles to the 70 degree striking regional foliation These narrow brittle to ductile high-strain zones are up to tens of metres wide and may contain concordant quartz veins, and millimetre- to centimetre-scale brittle shears or fractures. The NE striking high-strain zones display sinistral, oblique-slip displacement, while the NW-striking shears display dextral, olblique-slip displacement.

Dec 07, 2005 (A Wilson) - The occurrence has been described as a fine-grained dike of silicified porphyry intruding sheared mafic metavolcanic rocks. The porophyry is schisted an silicified in places. The sheared zone along the dike is 8-10 feet wide in places and a band about 2 feet wide heavily mineralized with sulphide lies in this zone.
