The North Star Amber occurrence is located at the head of Meadow Creek at 2360 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 greenschist facies.
The North Star Amber 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 deformed 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 10-centimetre wide brecciated quartz vein emplaced along a thrust plane that separates metasiltstone and carbonate rocks. The vein, which strikes 155 degrees and dips 60 degrees northeast, consists mainly of broken white quartz mixed in a black sulphide-rich gouge. A channel sample of the gouge material assayed 1978 grams per tonne silver, 1.17 per cent copper, 2.74 per cent lead and 1.14 per cent antimony (Assessment Report 18136). Narrow stringers of pyrite also extend through the metasiltstone. The vein is exposed in two trenches and a short, 9-metre long adit.
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 North Star 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).
