Summary(Plain Language Summary, not published)
This scientific presentation was given at the SEG-PDAC Student Mineral Colloquium during the 2018 Prospectors and Developers Association of Canada (PDAC) convention. It provides a summary of ongoing MSc research conducted through the Geological Survey of Canada's Targeted Geoscience Initiative to develop a 3D geological model of the Double Eagle - Black Thor intrusive complexes in northwestern Ontario. The 3D model is constrained by diamond drillhole datasets, geological maps and a revised structural interpretation based on drillcore re-logging and high-resolution magnetic data. Being able to visualize this complex hard-rock setting in 3D space will help unravel the subsurface architecture of the magmatic system and provide critical insight into the spatial relationship of the separate mineralization events.
