| Abstract | Bedrock-geology mapping was conducted in the summer of 2016 in the Tehery Lake - Wager Bay area on the northwestern coast of Hudson Bay, Nunavut, as part of amultiyear,multidisciplinarymapping campaign
led by theGeological Survey of Canada, through Phase 2 of the Geo-mapping for Energy and Minerals program (GEM-2), and the Canada-Nunavut Geoscience Office. Fieldwork resulted in the identification and spatial constraint of rock units in the northern
and western parts of the study area, which were sampled for geochemical, geochronological and petrographic analysis, as well as to assess their economic potential. Mapping has revealed the presence of a large granulite-facies metamorphic domain in
the southern part of the study area; the possibility of two different supracrustal rock sequences; thewestern continuations of the Chesterfield fault zone andWager shear zone; and generally high, but locally variable, peakmetamorphic conditions
across the study area. Further analytical work is required to fully characterize rock units, compare and correlate them with other well-studied units, and determine the geological history and economic potential of the Tehery Lake - Wager Bay area.

| Summary | (Plain Language Summary, not published)
Geology mapping was done in the summer of 2016 in the western and northern parts of the Tehery Lake-Wager Bay study area on the northwestern coast of
Hudson Bay, Nunavut. This work is part of a large multi-year project led by the Geological Survey of Canada's Geo-mapping for Energy and Minerals program and the Canada-Nunavut Geoscience Office. Rock samples were collected to analyze their
chemistry, age, and mineral make-up, and to find out if any have economic metals in them. The mapping revealed several new discoveries: 1) a large part of the southern map area has rocks that were changed due to high temperatures (800-900°C); 2)
there are two different groups of sedimentary rocks, likely deposited in different environments and times; 3) the Chesterfield fault and Wager shear zone were traced further to the east and west, respectively; 4) rocks in the study area have been
heated and pressurized due to mountain-building processes, but conditions were not the same everywhere. |
