Geoscience Map 2008-1 presents a 1:100 000-scale geology map in the northern Selkirk Mountains. 


The Selkirk Mountains straddle the boundary between rocks assigned to the North American miogeocline and the pericratonic Kootenay Terrane. Lower Paleozoic rocks of the northern Selkirk Mountains host numerous volcanogenic massive sulphide occurrences, that include the Goldstream copper-zinc mine, which produced 78 270 tonnes of copper and 8 000 tonnes of zinc from 2 221 228 tonnes milled until shut down in January, 1996 and the arsenical, gold-rich J&L deposit which has probable and possible reserves in excess of 5 million tonnes averaging 2.71 % Pb, 4.33 % Zn, 7.23 g/t Au and 72 g/t Ag. The stratiform nature of these deposits makes understanding the regional stratigraphic and structural setting fundamental to exploration for new VHMS deposits.


This 1:100 000 scale colour compilation map is based on fieldwork conducted between 1994 and 1996, compilation of 3 previously published 1:50 000 scale Open file maps as well as mineral exploration assessment reports. It covers approximately 2200 km2 of the northern Selkirk Mountains in the area that extends from the northern boundary of Mount Revelstoke National Park to the head waters of French Creek and from the headwaters of Goldstream River and Downie Creek west to Revelstoke Lake.


This map presents new geochronology, palaeontology, updated mineral occurrences and prospective exploration targets (exhalative horizons) to aid exploration for base metal deposits in this region.
