The Columbia VI showing is located 27 kilometres southeast of Port Alberni.

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.

A shear zone contains ankerite and quartz veinlets heavily mineralized with pyrite. A sample from a quartz or pyrite vein containing massive pyrite hosted in silicified basalt assayed 16.22 grams per tonne gold, 3.7 grams per tonne silver and 0.08 per cent copper (Assessment Report 17769).

The area was first explored by Gunnex Ltd. between 1963 and 1966. This work involved regional silt sampling and prospecting. Between 1985 and 1987, JBL Resources completed programs of geological mapping, geochemical sampling, prospecting and VLF-EM and magnetometer surveys on the area as the Kitkat claims. In 2011, Gold Ridge Explorations Inc. completed a regional program of litho-geochemical sampling, helicopter-borne versatile time domain electromagnetic (VTEM) and aeromagnetic geophysical surveys, totalling 34 square kilometres, on the area as the Columbia Shear property. 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.
