Capsule Geology

The George Lake showing is located on the northwest side of George Lake, approximately 23 kilometres northwest of Peachland.

The area is underlain by quartz diorite/granodiorite of the Early Jurassic Brenda stock, which is part of the Pennask Batholith.

Locally, as indicated by drilling, steeply south east- dipping quartz-feldspar veinlets host disseminated to blebby chalcopyrite and molybdenite mineralization. Barren quartz-microcline veins are noted in the area.

In 2007, diamond drilling intersected long intervals of weekly mineralized Brenda style copper-molybdenum mineralization. Results included (Assessment Report 30902):

During the exploration boom around the Brenda mine (MINFILE 092HNE047) in the 1960s, this showing was held by the Noranda Exploration Company Limited. In 1970, Arrow Inter-America completed an airborne magnetic survey, totalling 752 line-kilometres, on the area as the Tic and Toc claims. During 2006 through 2012, Bitterroot Resources completed programs of rock, silt and soil sampling, geological mapping, 147.6 line-kilometres of ground magnetic surveys, a 66.2 line-kilometre ground induced polarization survey and five diamond drill holes, totalling 1397.8 metres, on the area as the North Brenda property.
