Résumé(disponible en anglais seulement)
Analogous to kimberlites, base metal and uranium deposits have characteristic suites of indicator minerals that can be recovered from surficial sediments. However, limited research has been conducted to document the abundance and chemistry of these minerals within the deposits and how they are dispersed in glacial sediments. To address this knowledge gap, the Geological Survey of Canada (GSC) through its Geo-mapping for Energy and Minerals (GEM) Program, has collected suites of bedrock and till samples around two base metal and one uranium deposit in Canada. The objectives of these case studies are to characterize the geochemical and mineralogical signature of specific deposit types at the deposit- and camp-scale at varying distances up- and down-ice, to define background and to establish methods for indicator mineral recovery and characterization. Results from case studies at the Izok Lake Zn-Cu-Pb-Ag VMS deposit, Pine Point Pb-Zn MVT deposits, and the Kiggavik U deposit will be presented. These case studies add to the broad spectrum of commodities (diamonds, base and precious metals, uranium) that indicator minerals methods are now used for.
