In the winter of 2013 the Yukon Geological Survey (YGS) contracted Mira Geoscience to undertake a 3D geologically constrained modelling exercise to take advantage of a wealth of new geological and geophysical data. These data include new gravity and aeromagnetic surveys, new bedrock geology maps, rock property data and a seismic survey. The area of interest covers much of the northern Whitehorse trough south and east of Carmacks and extends west to Aishihik and Sekulmun Lakes. The goals of this project were to develop a better understanding of the geological relationships in an area of poor bedrock exposure, extending this knowledge to the subsurface and ultimately to provide insight into targeting for mineral and oil and gas exploration.
This project was funded under the SINED (Strategic Investments for Northern Economic Development) program. The new aeromagnetic surveys used in the development of the inversion models were products of the GEM (GeoMapping for Energy and Minerals) program of Natural Resources Canada. Detailed gravity surveys were funded through SINED and new bedrock mapping through YGS’s internal operating budget.
