As part of the Southern Mackenzie Surficial activity (2017-2020), under the Geological Survey of Canada's (GSC) Geo-mapping for Energy and Minerals (GEM-2) Program (2013-2020), stream sediments and till samples were collected across a 35,000 km2 region and processed for heavy minerals. This research activity is being conducted in a region with no prior surficial mapping and very limited surficial sampling for heavy minerals by Cominco Limited in the early 1980s (mostly industry-confidential data). Despite hosting the past-producing world-class Mississippi Valley-type (MVT) Pb-Zn district, almost no other mineral showings occurring at the bedrock surface have been documented in this extensive region, despite significant interpreted potential for additional mineral resources, and extensive reports of Pb-Zn mineralization at depth. In this paper we provide results which illustrate the potential for new, undiscovered targets in the region, and further highlight how heavy mineral assemblages and geochemical and isotopic compositions are powerful tools for exploration in glaciated regions.
