Geological Age: Neoarchean Geochronological Age: 2750 MA Geochron. Age Ref.: GOO VOL 1
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 consisting of quartz veins in a breccia zone within a mafic metavolcanic schist. The host rock has been altered to biotite.

Dec 07, 2005 (A Wilson) - The quartz veins are described as being crushed but having few sulphides. The vein system forks and the northwest branch contains vein quartz with some pyrrhotite and chalcopyrite. The gold samples from this locality have not given high assays and there are no reported assays from the occurrence.
