Geology Comments

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.

Lithology Comments

Dec 07, 2005 (A Wilson) - Host rocks include strongly deformed mafic metaintrusive rocks (gabbroic), pillowed mafic metavolcanic rocks and quartz-feldspar porphyry dikes. The mafic rocks are altered to Fe-carbonate, sericite, quartz and pyrite. Gold mineralization is hosted by quartz veins which occur in all of the host rocks, but are preferentially localized at the sheared contacts between the felsic porphyry dikes and the mafic rocks.

Mineralization Comments

Dec 07, 2005 (A Wilson) - Values in the zone are low but persistent across good widths. Diamond drilling completed in 1925 intersected values of 0.226 oz/t Au across 8.1 feet and 0.11 oz/t Au across 3 feet. In 1981 an average grade of 0.104 oz/t Au for a length of 220 feet. The highest assay returned from channel sampling completed by Patricia in 2000 was 106.21 g/t Au over 0.5 m (41.98 g/t Au over 1.5 m) from the A zone portion of the trench. The best assays from diamond drilling returned values up to 1.55 g/t Au. The C zone portion returned a best assay of 87.2 g/t Au.

Geologist: A Wilson

Notes: The No. 8 zone is localized within a 80-85 degree striking high-strain zone. The dominant foliation in the rocks surrounding the No 8 zone is oriented between 45 and 5 degrees with an 80 degree north dip. Brittle, brittle-ductile an dductile fractures are found in the immediate vicinity of the No. 8 zone.
