The Silver Sparrow occurrence is located at the head of Cascade Creek at 2285 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 two separate quartz veins some 90 metres apart. The Silver Sparrow vein consists of iron-stained quartz containing stringers of auriferous pyrite, argentiferous galena and minor sphalerite. The vein strikes 120 degrees, dips 30 degrees northeast and is about 1 metre thick where it is exposed in the trenches. The vein has also been exposed in a 6-metre deep inclined shaft. The best grab sample from the vein assayed 27.5 grams per tonne gold, 1083 grams per tonne silver, 56.2 per cent lead and 0.55 per cent zinc (Assessment Report 18136). The Pine Tree vein is situated 90 metres west of the Silver Sparrow and has similar mineralogy. The vein is exposed for about 20 metres in three trenches. The vein strikes 071 degrees, dips 30 degrees northwest and ranges in width from 7 to 50 centimetres. Both veins are hosted within siltstone of the Broadview Formation.

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 Silver Sparrow 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 (082KSW125), West Ridge (082KSW197), and White Eagle (082KSW126) showing areas (Assessment Report 23669).
