This map was generated from digital geological compilations of the Kootenay Mineral Assessment (Höy et al., 1994) and the East Part of the Okanagan Mineral Assessment (Schiarizza and Church, 1996). Both are available on the Ministry of Mines "Map Place" web site and contain extensive and complete reference lists of government, university and industry research, maps and published reports. Modifications incorporate age determinations and more recent mapping associated with the Intrusive-related gold deposits project (1999-2001) and references within. The intrusion-related mineralization shown represents an updated subset of the MINFILE database for NTS 82F,G,K,M,N. The base map is North American Datum 1983, Zone 11, Transverse Mercator Projection. This map was reviewed by B. Grant, T. Höy, D. Lefebure and P. Schiarizza.
