The West Ridge occurrence is located at the head of Cascade Creek at 2225 metres elevation above sea level in the Slocan Mining Division.
Regionally, the area lies within the Selkirk Mountains of southeastern British Columbia. The occurrence is within the Kootenay Arc, a curving belt of highly deformed metasedimentary and metavolcanic rocks which includes the Upper Proterozoic Horsethief Creek Group, the Upper Proterozoic to Lower Cambrian Hamill Group, the Lower Cambrian Badshot Formation, and the Paleozoic Lardeau and Milford groups. The volcano-sedimentary sequence is intruded by numerous Paleozoic to Mesozoic granitoid plutons and has been metamorphosed to at least middle greenschist facies before the emplacement of the mineralization.
The West Ridge property is underlain by andesite, sandstone, siltstone and phyllite which forms the lower portion of the Broadview Formation of the Lardeau Group. The rocks have been folded in a series of northwest-trending folds that were subsequently thrusted in a northeasterly direction along local faults (Geological Survey of Canada Bulletin 193).
The occurrence consists of a 30 centimetre wide milky quartz vein striking 119 degrees and dipping 45 degrees southwest. The vein is mineralized with disseminations and pods of argentiferous galena, tetrahedrite and stibnite. A selected grab sample of the mineralized vein assayed 1540 grams per tonne silver, 41.1 per cent lead, 16.1 per cent antimony and 1.58 per cent copper (Assessment Report 18136).
The vein has been explored with several trenches and a 15-metre deep shaft. Boulders of massive galena-stibnite mineralization up to 1 metre across are reported from a dispersion train below the workings for a distance of 137 metres (see Noonday, 082KSW127 - Prospectus, Ambergate Exploration Inc., 1988)
During 1987 and 1988 Ambergate Explorations conducted an exploration program which consisted of 1:10000 scale mapping, a soil survey, and trenching on their Amber 1-4 claims in which the West Ridge showing is located. A follow-up to the 87-88 exploration program was done in 1994 by Lumby Resources Corporation, an optionee of Kenrich Mining Corporation, formerly Ambergate Explorations. This program extended the soil survey in the West Ridge, Juno (082KSW125), and White Eagle (082KSW126) showing areas (Assessment Report 23669).
