Summary(Plain Language Summary, not published)
This geological map covers part of an ancient volcanic belt of the Northwest Territories known as the Great Bear magmatic zone (GBMZ). The area hosts the NICO deposit (gold-cobalt-bismuth-copper), one of two Iron Oxide Copper-Gold (IOCG) deposits discovered in Canada. The Multiple Metals-Great Bear Region Project, Geomapping for Energy and Minerals Program (GEM, 2008-2013), undertaken by the Geological Survey of Canada and Northwest Territories Geoscience Office, has expanded the mineral potential of the GBMZ from known IOCG to related deposit types that could provide base, precious and high-technology metals including those to produce green energy technology. This map is based on data gathered under the Canada-Northwest Territories Mineral Development Subsidiary Agreement (1987-1991), unpublished until now. The Tlicho government opened the area for mineral exploration in spring, 2013, so it is timely to release all relevant documents.
