| Abstract | The Neoproterozoic Coates Lake Group is a known host for copper mineralization in the central Mackenzie Mountains. The previously documented 300 km long northwest-southeast trending outcrop belt of
Coates Lake Group is extended by approximately 85 km to the northwest based on mapping observations from the Geo-mapping for Energy and Minerals program of the Geological Survey of Canada. Two units of the Coates Lake Group, Thundercloud Formation
and Coppercap Formation, are herein documented from the Bonnet Plume Lake (NTS 106B) and Ramparts River (NTS 106G) map areas, including the region around Arctic Red River. No evidence of copper mineralization within the Coates Lake Group was observed
in the Bonnet Plume Lake or Ramparts River map areas; however, observations in the region are limited. |
| Summary | (Plain Language Summary, not published)
This report documents the distribution of a copper-bearing map unit known as the Coates Lake Group in the northwestern Mackenzie Mountains of the
Northwest Territories, in a region where it had not previously been documented. No copper mineralization was observed in the newly documented area. |
