Capsule Geology

The Columbia VI East occurrence is located at an elevation of approximately 280 metres on the east side of a ridge separating Rift Creek and the Nitinat River, approximately 2.4 kilometres north of their junction.

The area is underlain by rocks of the Devonian Nitinat Formation and the Upper Devonian McLaughlin Formation which occur along the western part of a 10-kilometre belt of the Paleozoic Sicker Group, known as the Cowichan uplift. The volcanics consist of massive and pillowed basalt with minor chert and jasper. Small patches of epidote, and lesser amounts of quartz are common throughout the sequence. These rocks are steeply dipping and become younger to the west. The metamorphic grade is usually lower greenschist facies.

Locally, a 150 square metre area of float and outcrop contains silicified chloritic volcanic rocks with pyrite and chalcopyrite mineralization.

In 2017, three samples (1726, CS-R1724 and CS-R1725) assayed 4.55, 2.47 and 2.2 per cent copper, respectively, with up to 5.5 grams per tonne silver (MacIntyre, D. (2017-10-12): Amended Technical Report - Columbia Shear Mineral Property).

Work History

In 2012 and 2013, Golden Peak Minerals Inc. completed programs of geological mapping, geochemical (soil, rock, and silt) sampling and a 24.35 line-kilometre ground magnetometer survey on the area. In 2017, New Point Exploration Corp. completed a program of rock, soil, silt, and moss mat sampling on the area as the Columbia Shear property.
