Name: GQ, PERRY RIVER, SECOND CREEK, SW, SE, NE
Several new pegmatite-related Au-W-Cu-Bi occurrences were discovered northeast of Shuswap Lake in September, 1999 by geologist Warner Gruenwald. He was following up silt samples with anomalous gold values that he had collected during the summer. The showings outcrop on new logging roads in the Second Creek drainage, a northwest flowing tributary of the Anstey River. The GQ claims were staked in fall 1999 to cover the area.
Quartz-sulphide zones have been located in outcrop over an area of about 1.5 by 1.5 kilometres on the GQ claims, and anomalous gold values have been encountered at the SW, SE and NE showings. The mineralization is hosted by garnet-bearing paragneiss, orthogneiss and quartz-mica schist, and lesser calc-silicate rock, marble and amphibolite of the Shuswap metamorphic complex. These high-grade metamorphic rocks occur in the hangingwall of the Monashee decollement, to the west of the Frenchman's Cap gneiss dome, part of the Monashee complex. Massive to foliated, granitic intrusive rocks of the mid-Cretaceous Long Ridge pluton (92-94 Ma, U-Pb, R.R. Parrish, 1995, CJES Vol. 32) occur a few hundred metres to the west of the SW showing. The schist/gneiss package is also intruded by abundant pegmatite dikes, some of which contain tourmaline and minor pyrrhotite.
Mineralization consists of 10 to 30 centimetre wide lenses of quartz, calc-silicate and sulphides which occur along the margins of conformable or slightly discordant, locally tourmaline-bearing pegmatite sills, where they are in contact with marble or schist. Sulphide content ranges from a few percent up to 20-30 per cent in semi-massive pods, consisting mainly of pyrrhotite, minor pyrite and traces of chalcopyrite and scheelite.
