| Abstract | The Mazenod Lake - Lou Lake area is centred in the southern Great Bear magmatic zone, Wopmay Orogen, Northwest Territories. The area comprises a 1.87-1.84 billion year old volcanic and plutonic terrane
interpreted as a continental magmatic arc that developed on a locally exposed metamorphosed and tilted sedimentary basin. Intense alteration is superimposed on supracrustal rocks culminating in a diversity of mineral occurrences that range from
iron-oxide-copper-gold (IOCG), including the NICO and Sue-Dianne deposits, to late vein-hosted uranium deposits, including the past-producing Rayrock Mine. This geological map was compiled in 1999 following Geological Survey of Canada fieldwork from
1987 until 1996, initially under the Canada-Northwest Territories Mineral Development Subsidiary Agreement (1987-1991). Updates and transformation of this map into a GIS-ready publication was supported by Multiple Metals - Great Bear Region,

| Summary | (Plain Language Summary, not published)
This geological map of the Mazenod and Lou Lake area covers the south end of an ancient volcanic belt of the Northwest Territories named Great Bear
magmatic zone. The area hosts the two Iron Oxide Copper-Gold (IOCG) deposits discovered in Canada: NICO and Sue Dianne (gold, cobalt, bismuth, copper, silver). Resources total 40 million tons (Mt) and the Multiple Metals?Great Bear Project,
Geomapping for Energy and Minerals Program (GEM, 2008-2013), launched by the Geological Survey of Canada and the NWT Geoscience Office, has now shown a broader IOCG and affiliated deposit potential for base, precious, high-technology, green-energy
and nuclear metals. This geological map, compiled by Dr. Sunil Gandhi in 1999 under contract for Hudson Bay Exploration, is based on data gathered under the Canada-Northwest Territories Mineral Development Subsidiary Agreement (1987-1991) and updated
by GEM. Last spring, the Tlicho government opened the area for mineral exploration. Publication of this map in support of future mineral exploration and resource development is therefore very timely. |
