Capsule Geology

The Copper 6 occurrence is located near a small creek on a plateau to the east of Thunder Creek, approximately 4.5 kilometres north of its mouth on the Bridge River.

The area is underlain mainly by intrusive rocks of the Lord Pluton, an Early Tertiary intrusive complex of the Coast Plutonic Complex. Locally, Pleistocene volcanic rocks of the Garibaldi Group overlie the pluton. The dominant rock types include quartz monzonite, biotite granodiorite and quartz diorite with minor amounts of gabbro, hornblendite and intrusive breccia. Dykes of aplite, andesite, feldspar porphyry and gabbro also cut older intrusive rocks.

Locally, four zones (Number 3, Contact, Windy and West) of mineralization are exposed near the contact with the overlaying Miocene basalts over an area of 400 by 1000 metres. The zones consist of a mineralized quartz stock work hosted by sericite- altered granites of the Bridge River pluton. Mineralization consists of chalcopyrite, bornite and tetrahedrite. The zones are west- dipping and primarily north to north west trending, 025 to 040 degrees.

A historic sample, from 1931, is reported to assay an average of 3.36 per cent copper over 9.1 metres from four samples; while a 24.5 metre open cut across the zone yielded 0.44 per cent copper (Assessment Report 28271).

In 2008, a grab sample from the Number 3 zone yielded values up to 5.31 per cent copper, 0.076 per cent molybdenum, 88.3 grams per tonne silver, 0.31 gram per tonne gold and 0.194 per cent antimony. A sample from the Contact zone assayed 0.22 per cent copper, 0.006 per cent molybdenum, 15.8 grams per tonne silver and 0.106 per cent antimony over 0.8 metres (Assessment Report 30991).

In 2012, sampling immediately to the west of the known occurrences along a 350 metre long north trending zone of copper mineralization, yielded values up to 1.53 per cent copper, 0.20 per cent molybdenum, 9.2 grams per tonne gold and 52.3 grams per tonne silver (Sample 15405; Assessment Report 32065).

The area was originally explored by Cominco in the 1930’s. During 2005 through 2012, programs of prospecting, geochemical sampling, trenching and an induced polarization survey were completed on the area as the Copper 1-25 claims.
