| Abstract | This report releases the field database and analytical results from a targeted stream sediment and till sampling survey completed during six days in 2016 over parts of NTS 76-H and 76-I as part of the
Geological Survey of Canada's GEM-2 Thelon tectonic zone project, southeast of Bathurst Inlet, mainland Nunavut. The survey covers parts of the Thelon tectonic zone and adjacent Slave craton, and crosses the terminus of the Dubawnt Lake ice
stream.
Field observations and geochemical data from 39 stream sampling stations are published in spreadsheet format. Mineralogical data derived from heavy mineral concentrate samples collected at 17 of the 39 stream stations are included with
this report. Surface till samples were collected at 11 field stations proximal to stream stations. Matrix geochemistry, indicator minerals, clast lithology and grain size distribution were determined in till samples. Field observations and till
compositional datasets appear in separate spreadsheets in the appendices. A preliminary interpretation of the combined datasets with implications for mineral potential in three follow-up areas is presented at the end of the report. |
| Summary | (Plain Language Summary, not published)
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 stream 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. |
