Sep 26, 2016 (A Wilson) - The area lies between two NNW trending faults and the observed deformation is believed to be related to the Goudreau Lake Deformation Zone that lies to the west. The GLDZ is up to 4.5 km in width and strikes in a gentle sigmoid-form for at least 30 km, sub-parallel 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. 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.

Dec 07, 2005 (A Wilson) - Elevated gold and copper values have been obtained from a folded iron formation hosted by intermediate to mafic metavolcanic rocks.
Dec 07, 2005 (A Wilson) - Grab samples from a series of bedrock trenches returned assays of 13.85 g/t Au and 30700 ppm Cu; 3870 ppb Au and 30400 ppm Cu.
