AbstractThe Canadian Arctic Islands contain many areas that have a high mineral potential. Five geological assemblages are recognized: crystalline Archean to Paleoproterozoic basement; Mesoproterozoic sedimentary basins and volcanic rocks; Lower Paleozoic passive to convergent margin sedimentary rocks, Upper Paleozoic to Mesozoic rift basin sediments and volcanic rocks; and Tertiary passive margin sediments. To date, only two mines have been put into production in the islands: Paleozoic Mississippi Valley-type (MVT) carbonate-hosted Zn-Pb Polaris Mine on Little Cornwallis Island and Proterozoic MVT carbonate-hosted Zn-Pb Nanisivik Mine on northern Baffin Island. There is high mineral exploration potential around these past producers, as well as around known showings of Proterozoic-hosted redbed copper on Victoria Island and Paleozoic-hosted polymetallic (Zn-Pb-Ag-Au) veins on northern Ellesmere Island. There is
also potential for as-yet-unfound i) Zn-Pb SEDEX deposits in the Proterozoic on northern Baffin Island and in the Paleozoic on Melville, Bathurst, and Ellesmere islands; ii) sediment-hosted uranium in the Proterozoic of northern Baffin Island, in the Paleozoic of Melville Island, and in Mesozoic and Tertiary of Banks and Prince Patrick islands; and iii) Noril’sk-style Ni-Cu-PGE deposits in the Proterozoicon Victoria Island and in the Mesozoic on Axel Heiberg Island.

The Canadian Arctic is logistically challenging, making it expensive to explore and develop mines. Mineral exploration is also hampered by a lack of local prospectors, large areas that are mapped in insufficient detail, and the lack of digitally available topography, bedrock and surficial mapping, airborne geophysics, and hyperspectral surveys.
