Metamorphism Grade: Greenschist
Nov 16, 2010 (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 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. 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 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.

Nov 16, 2010 (A Wilson) - The best assays are associated with massive to pillowed mafic metavolcanic rocks and with sheared mafic metavolcanic rocks. The B Zone is east-striking and dips 85° north. The shear zone occurs along the contact between mafic metavolcanic rocks and iron formation. The mineralized zone ranges from 0.3 to 2.5 m wide.
Nov 16, 2010 (A Wilson) - The best assay obtained by Algoma Steel was 0.09 oz/t Au and 860 ppm Zn from a grab sample from a trench. A grab sample from sheared mafic metavolcanic rocks approximately 180 m to the south east returned an assay of 0.05 oz/t Au, 1520 ppm Zn and 470 ppm Cu. Gold assays from sampling completed by Pele Gold returned values ranging from 1.34 to 23.2 g/t Au over a distance of approximately 50 m along strike.
