The Logan showing is located on Rift Creek near its outlet into the Nitinat River.
The showing occurs at the southern extent of the Cowichan Thrust which cuts through the Logan claims. Paleozoic Sicker Group rocks comprising of the Devonian Nitinat and/or McLaughlin Ridge formations, are exposed in the hangingwall of the fault. The Sicker Group rocks are intruded by Jurassic Island Plutonic Suite. In the footwall, rocks of the Nitinat Formation are intruded by Triassic diabase sills and overlain in fault contact with pillowed and massive flows of the Upper Triassic Karmutsen Formation, Vancouver Group.
Mineralization occurs primarily on the Logan 2 claim which staddles the northwest striking fault zone. Outcrops in this area show intensive fracturing, shearing and brecciation and silicification, epidotization and pyritization are reported. Mineralization consists of pyrite and chalcopyrite in silicified zones and as fillings in vugs and narrow fractures.
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 1988, Anthony Resources completed a prospecting program. Fourteen chip samples averaged 6.44 grams per tonne gold and 6.34 grams per tonne silver with a maximum value of 12.75 grams per tonne gold and 10.97 grams per tonne silver (Property File - Antony Resources Ltd. Prospectus, May 1988).
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.
