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 mine access road is located approximately 2 km east of the junction of the new Goudreau Road and the old Goudreau Road. The showing is accessible via the road to the mine water intake line.
Pre-1927: trenching and sampling. 1929: Algoma Exploration Company - sampling.

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 is described as cellular vein quartz in association with chlorite schist. The Kremzar float is thought to have come from this showing due to a similarity in appearance.
Dec 07, 2005 (A Wilson) - Gledhill (1927) indicates that gold could be panned in the oxidized zone but was scarce in the solid rock below.
