| Summary | (Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience
knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. High-resolution airborne hyperspectral imagery was collected over the Hope Bay Volcanic Belt, Nunavut. Our analysis of
the imagery obtained for the area indicates that the method is effective in mapping the distribution of so-called hydrothermal alteration minerals that are associated with known gold and base-metal mineral deposits and which occur around them, and
also highlights areas for which there are no known deposits. The remotely sensed data can be incorporated together with existing geological and geophysical datasets to produce predictive maps of orogenic gold deposit locations. Thus, hyperspectral
remote sensing is a viable part of the mineral explorationist¿s toolbox of methods in some parts of Canada¿s north. |
