Résumé(disponible en anglais seulement)
To assist mineral exploration in northern Canada, several indicator mineral research activities were undertaken at the Geological Survey of Canada as part of the Geomapping for Energy and Minerals (GEM) Program (2008-2013). Project goals included: 1) the compilation/database population of heavy mineral data collected from surficial sediments in Canada's north, 2) improving and publishing a till sampling protocol for till geochemistry and heavy minerals, and 3) methodology development to demonstrate how indicator minerals can be used to explore for various commodities.
Information about indicator mineral data is continually being acquired from published government reports, assessment files, unpublished reports, and private exploration company holdings. These data will complement the KIDD-KIMC and till geochemistry data sets provided by territorial partners, and include indicator minerals of all commodities. The information is captured in the Canadian Database of Geochemical Surveys (CDoGS), which accommodates the comprehensive metadata required for all varieties of geochemical and indicator mineral surveys. The CDoGS web portal ( exposes these surveys in query-able fashion so that those of interest can be identified for further examination. The results of various indicator mineral commodity types are displayed using Google EarthTM, where instant linkages and interpretations can be made from seeing the data plotted in association with regional glacial landforms.
Drift prospecting research, in collaboration with industry and academic partners, was initiated at the Izok Lake Zn-Cu-Pb-Ag VMS deposit and Kiggavik uranium deposit in Nunavut and the Pine Point Pb-Zn MVT district in the Northwest Territories. These study areas are located in regions either affected by multiple ice flow trajectories, ice divide migration, or thicker glacial drift. Landforms, striae, clast dispersal, till stratigraphy, till geochemistry, till micromorphology and indicator minerals provide records of simple to complex net transport. Preliminary results, from GSC Open Files published and/or in press are presented and provide the exploration industry with a proven methodology for mineral exploration in the glaciated terrain of northern Canada.
