The purpose of the project, which is part of a collaborative Targeted Geoscience Initiative III (TGI-3) project with the Geological Survey of Canada, is to determine whether gneiss equivalent to the nickel-bearing Ospwagan Group, which has an Archean provenance in the Thompson Nickel Belt (TNB), is also exposed within dominantly Burntwood Group greywacke gneiss at Kawaweyak Lake. Mapping during 2007 showed that the Burntwood Group greywacke gneiss and psammitic to semipelitic units of quartz-rich, calcareous and biotitic gneiss at Kawaweyak Lake are in gradational contact with a distinctive amphibolite–iron formation assemblage. The latter assemblage, which is well exposed at the south end of the map area, can be traced 6 km northeast along strike to the eastern shoreline of Notakikwaywin Lake. A Nd model age of 2.15 Ga on a sample of the semipelite from the quartz-rich rocks at the south end of the Kawaweyak Lake is not consistent with an affinity for the Ospwagan Group, and more consistent with belonging to the juvenile Paleoproterozoic Burntwood Group or an assemblage of amphibolite and siliciclastic rocks that generally overlies the Burntwood Group. The amphibolite has minor gold showings south of Granville Lake, northeast of the map area.
