Summary(Plain Language Summary, not published)
This report presents data and maps for indicator minerals recovered from surficial sediment sampled during a survey undertaken by the Geological Survey of Canada in 2012. The study area is bounded by Mary Frances Lake (to the northeast), Whitefish Lake (to the southwest) and the Thelon River (to the east), and lies to the southwest of the Thelon wildlife sanctuary and to the east of the area of interest for Thaidene Nene. Results from this study suggest potential for mafic-ultramafic related styles of mineralization, and Mn-rich banded iron formation (BIF) in the vicinity of Williams Lake. Ultramafic-mafic and BIF rock types have not previously been recognized in the study area.
