AbstractThe Non-renewable Resource Assessment is a legislated requirement in the Northwest Territories' Protected Area Strategy and is used to facilitate informed decision making on land use issues, special management areas, protected areas, and the establishment of territorial parks. Two Resource Assessments detailing the Mineral and Petroleum potential of the proposed protected area are completed for each area. If these protected areas are granted as such, it is possible that this study may be last geochemical/mineralogical survey conducted within the boundaries of any area that is a candidate for protection. The NRA process is designed to provide as much information as possible on the mineral potential of the proposed protected area and it covers a multitude of potential mineral deposit targets. Thus, an extensive suite analysis is carried out on tills including geochemical analysis of the -63 micron fraction of the indicator minerals. Indicator minerals from a wide variety of deposit types, e.g. kimberlite, base and precious metals and other pathfinder minerals are being evaluated from bulk glacial sediment samples as well. In areas of low relief, basal till is the targeted sample medium whereas in areas with higher relief, stream sediments, and waters as well as pre-concentrated and screened bulk stream sediments are the target media. Since some of the proposed protected areas are composed of low-relief as well as mountainous areas, sometimes a hybrid approach has been employed. The objective is to provide detailed and pertinent information in support of balanced decision-making.
