The Wolfenden (Coqueis) showing is located on Coqueis Creek, south of Quatsino Sound.
The area is underlain primarily by andesite flows and tuffs of the Lower Jurassic Bonanza Group. The volcanics are underlain by calcareous siltstones, shales, sandstones and limestones of the Upper Triassic Parsons Bay Formation. These have been intruded by quartz diorites of the Lower to Middle Jurassic Island Plutonic Suite.
The Coqueis showing is exposed for 65 metres in a stream bed, 5 metres wide, in a tributary of Coqueis Creek. Mineralization, consisting of sphalerite, pyrite, minor pyrrhotite and trace chalcopyrite, occurs associated with silicified and brecciated andesites.
The showing averages 0.86 gram per tonne gold, 9.6 grams per tonne silver and 2.78 per cent zinc; with individual samples returning up to 3.55 grams per tonne gold, 11.8 grams per tonne silver and 9.10 per cent zinc (Assessment Report 30273).
Work History
The area was originally explored in the late 1980’s, after a regional stream silt survey identified anomalous gold, silver and zinc values in the area. These claims were allowed to lapse. In 2007, A.I. Betmanis restaked the area and continued exploration through 2008. During 2015 through 2019, Karmamount Mineral Exploration Inc. completed minor programs of geological mapping and geochemical (rock and soil) and biogeochemical sampling and a 12.9 line-kilometre induced polarization survey on the area as the Yreka property.
