Geology Comments

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.

Lithology

Lithology Comments

Dec 07, 2005 (A Wilson) - The occurrence reportedly lies within a segment of brecciated iron formation separating the cycle 2 metavolcanics from the cycle 3 metavolcanics.

Mineralization

Mineralization Comments

Dec 07, 2005 (A Wilson) - The Cu-Zn mineralization is present as disseminations across a width of 1 to 3 feet in the mineralized zone. The mineralization is irregular and spotty in distribution. Most mineralization occurs as narrow veinlets and splashes within pyrite. Assays from diamond drill core collected by Canex returned a best assay of 0.02% Cu and 0.10% Zn. A grab sample reportedly assayed 5.5% Cu.
