Aug 04, 2022 (Q Unknown) - The occurrence is located within a wide east-trending sheared and carbonatized quartz feldspar porphyry dike which intrudes mafic metavolcanic rocks of the Kawashegamuk Lake group (Kresz 1987). The felsic dike is strongly altered to sericite and iron carbonate. On the north wall of the open cut, the schistosity (130°/79° NE) is seen to be rotated into the shear fabric (140°/90°) indicating a west-side-down, dip-slip sense of movement in the shear zone. Two quartz veins in the north wall of the open cut strike 140°/90° and 160°/ 66° E respectively, and merge together at the bottom of the wall. The quartz-carbonate veins are white to light grey in colour, and opaque. The quartz has a ribbon texture defined by layers of chlorite. Mineralization consists up to 2% pyrite and chalcopyrite, with some visible gold. The two veins vary from 4 cm to 56 cm wide where they merge, and can be traced over a 15 m length beyond the end of the open cut. Six grab samples were taken by the author. The best samples returned 0.34 ounce gold per ton, 8620 ppb, and 5720 ppb gold on analysis. (OFR 5731, p. 93 - 95)
