The Snowstorm occurrence is located at the head of Cascade Creek at 2255 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 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 quartz veins containing minor galena, sphalerite, and pyrite mineralization hosted within siltstone of the Broadview Formation. The veins are exposed in 26 trenches covering an area of about 7.5 hectares. The largest vein is about 1 metre wide, strikes 313 degrees and dips 39 degrees to the east. Grab samples have assayed 572 grams per tonne silver, 2.81 grams per tonne gold, 22.4 per cent lead, and 0.06 per cent zinc (Assessment Report 16433; 23669).
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 Snowstorm 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 Juno, West Ridge (082KSW197), and White Eagle (082KSW126) showing areas (Assessment Report 23669).
