Contents

The Geological Survey of Canada carried out geochemical and indicator mineral surveys of tills, stream sediments and waters under the GEM Program in 2012 and 2014 in the Duggan Lake-Ellice River area of Nunavut (NTS 76-H and 76I).  Results revealed two areas with elevated concentrations of base elements (Pb, Cu, Zn, Ag) in silts and one area with gold potential.  Follow-up surveys in these three areas were carried out in 2016.  This open file contains field observations and geochemical data for the till and stream sediment samples collected in 2016. Mineral grains identified in the heavy mineral fraction of tills and stream sediments are reported in separate data spreadsheets.  Geochemical and indicator mineral data support results from earlier surveys indicating potential for both base and precious mineralization in the survey areas.
