Sep 24, 2016 (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.

Sep 24, 2016 (A Wilson) - A flat-lying kimberlite dike was intersected at depth. It is described as a lamprophyre in the drill logs. It is black in colour, biotite rich and fine-grained. Some descriptions identify a reddish colouration to the dike. Analysis of the dike by De Beers revealed 28 garnets from 9 kg of core, of which 26 are G9 and the remaining 2 are G-10 type garnets. Several of the probed spinel grains fall within the diamond inclusion field. The majority of the spinels are considered to be mantle derived. The clinopyroxene that was probed all plot within the vicinity of garnet-peridotite compositional fields. Kimberlite was identified in DDH 97- 31, 97-33, 97-34, 97-35 and 97-36. The dike is narrow and in sharp contact with the surrounding mafic to intermediate metavolcanic rocks.
