The Shell No.17 occurrence is located at 1173 metres elevation on the southeastern slopes of Anarchist Mountain, 8 kilometres due east of Osoyoos, British Columbia. The Shell No.17 is located on the southwest corner of the Ket 30 claim.
The showing is underlain by metaquartzite, chlorite schist, quartz-biotite schist, black phyllite and greenstone of the Carboniferous to Permian Anarchist Group. These metasediments have been highly metamorphosed. Chlorite and sericite alteration are prevalent. Foliated hornblende granodiorite, granite, quartz monzonite and syenite of the Middle Jurassic Nelson intrusions have intruded these Anarchist rocks to the immediate southwest. The main foliation strikes 140 degrees and dips 70 degrees east. Some tight folds were observed.
The showing consists of a massive sulphide breccia developed adjacent to the contact between granodiorite and siliceous quartzite. It appears to follow the main foliation which strikes 130 degrees and dips 50 degrees southwest. Mineralization consists of massive pyrite, pyrrhotite with minor sphalerite, chalcopyrite and galena banding, interlayered with chlorite and sericite schist. Good silver values are reported associated with massive sulphides (Assessment Report 2926). Dump material indicates massive mineralization to be a minimum of 1.5 metres wide. Widespread banded pyrite mineralization was traced over an area 400 by 700 metres around the shaft. The mineralization suggests the potential for stratiform or volcanogenic massive sulphide type mineralization.
Rock grab samples taken from this shear zone in 1971 yielded 2.23 to 2.36 per cent zinc, 0.10 to 0.12 per cent copper, trace to 0.3 per cent lead, up to 3.4 grams per tonne silver and trace nickel and gold (Assessment Report 2926). Several rock samples taken in 1991 yielded the following results. Sample 91KT14-D39R returned 0.05 gram per tonne gold, 0.20 per cent copper and greater than 1 per cent zinc (Assessment Report 22199). Sample 91KT14-D137R yielded 0.10 gram per tonne gold, 6.0 grams per tonne silver, 0.10 per cent copper and 0.30 per cent zinc (Assessment Report 22199).
Work History
The Shell No.17 showing was first discovered at the turn of the century. A 21-metre shaft was sunk on the showing in 1903. Two 15-metre drifts extended from the bottom of the shaft. Several surface trenches were also dug but are now backfilled. A trench, in quartzite, was found 305 metres to the southeast. The showing is currently owned by Crownex Resources (Canada) Ltd.
During 2008 through 2012, Grizzly Discoveries Inc. completed programs of geochemical (rock, stream sediment and soil) sampling, geological mapping and airborne and ground geophysical surveys on the Dayton-Sidley area of the Greenwood Property.
