5203 |a"The geophysical data sets available for the western Churchill Province have had a bearing on the understanding of its structure, evolution and metal endowment. New data were acquired and interpreted during the Geo-mapping for Energy and Minerals (GEM) Program (2008-2020). Regional, high-resolution aeromagnetic, and targeted gravity and magnetotelluric surveys were collected in GEM, in conjunction with geological mapping projects, in order to provide control on bedrock features beneath widespread glacial overburden and flat-lying sedimentary basins. Quantitative estimates of three-dimensional geometry were obtained in key areas through geophysical models integrating the geophysical characteristics with local rock property measurements. These geophysical data sets contributed to new knowledge and interpretations in three related research fields: 1) location and nature of Rae craton's boundaries within the western Churchill Province; 2) definition of internal Rae architecture; and 3) identification of reactivated structures controlling gold and uranium mineralization. The new data, models and emerging tectonic and metallogenic frameworks will serve as guides for future exploration in this remote, complex, challenging region"--Abstract, page 1.
