Capsule Geology

The Monkey showing is located 27 kilometres east of Port Alberni. Two old short adits, driven on a gold-bearing quartz vein, were found on this claim.

The area is underlain by rocks of the Paleozoic Sicker Group comprising the Upper Devonian McLaughlin Ridge Formation and the Devonian Nitinat Formation. These rocks consist primarily of andesitic, basaltic and dacitic tuffs and flows, lesser argillite and chert and minor conglomerate or breccia.

A conformable quartz vein occurs within a thick band of argillite. The vein is heavily mineralized with pyrite (up to 50 per cent) and sphalerite (up to 10 per cent), and minor chalcopyrite and galena. The vein is up to 7.5 centimetres wide with a 7.5 centimetre zone of silicified wallrock containing many quartz stringers, and has been traced for 120 metres. Two other small quartz veins, one possibly an offshoot of the main vein and the other similar in appearance but thinner, occur in the area. A fault is parallel to the main vein 2 to 3 metres to the north and separates argillite from Tertiary(?) feldspar porphyritic andesite, believed to be intrusive.

A 1984 grab sample from a quartz vein assayed 1.04 grams per tonne gold, 10.8 grams per tonne silver, 0.13 per cent copper, 0.07 per cent lead and 1.08 per cent zinc (Assessment Report 12564).
