Abstract(unpublished)
Mineral resources of Arctic Canada are most notably associated with the Canadian Cordillera of Yukon and western Northwest Territories, the Slave craton of Northwest Territories and Nunavut, the Rae and Hearne cratons and the Paleoproterozoic orogens including Wopmay Orogen west of the Slave craton and the Trans-Hudson Orogen (Cape Smith belt) of northern Quebec. The Canadian Cordillera (and Arctic Canada in general) features important resources of Mississippi Valley-type deposits (seven), sedimentary-exhalative (Sedex) deposits (five), lode gold deposits of various kinds (14), polymetallic silver lead zinc (five), volcanogenic massive sulphides (VMS, four), porphyry deposits (five), copper and tungsten skarns (six), nickel copper PGE (one) and placer gold (11 districts) of which the largest is the Klondike. The Slave craton is noted for its orogenic gold deposits (12), VMS (three), productive kimberlite camps (five) and a REE deposit. The Rae craton features iron (two), orogenic gold (four), uranium (four), nickel (one) and commercially-significant kimberlites (two). To the south and east, the Hearne craton has nickel (two), uranium (one), VMS (one) and orogenic gold (one). In the Paleoproterozoic orogens mineral resources are associated with ultramafic rocks in the Cape Smith belt (nickel copper PGE: three deposits), and in the Great Bear batholith of Wopmay orogen where resources include iron oxide copper gold (two), polymetallic veins (two) and vein uranium (one).
Summary(Plain Language Summary, not published)
This report provides readers with an overview of the known mineral deposits of Yukon, Northwest Territories and Nunavut. It is accompanied by ten map figures that serve to locate the deposits, and seven plates that illustrate the rocks containing ore minerals and the setting of established mines. The mineral wealth of the territories amounts to deposits of zinc and lead (12) some mined out, copper and zinc in a volcanic setting (8), lode gold (27) several exhausted, placer gold (11 districts), copper and gold associated with iron oxides (5), polymetallic silver veins (7), nickel copper and platinum group elements (7), intrusion-related copper-molybdenum deposits (5), copper and tungsten skarns that have formed in the aureole of young intrusive rocks (6), diamond deposits (5), sedimentary iron (4), and a rare earth deposit.
