Remotely sensed data have been used to assist in mineral exploration for decades, with applications in bedrock and surficial geological and alteration mineral mapping ,which can
be integrated with other data for remote predictive mapping or prospectivity analyses. Here, we present remotely sensed data for the Hope Bay orogenic Au deposit and the Hackett River Ag-bearing VMS deposit, both in Nunavut, Canada. Data from three
different sensors types will be examined: airborne hyperspectral imagery from the Geological Survey of Canada¿s SINED survey in 2009, commercially available Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data, and WorldView-3
from DigitalGlobe¿s satellite launched 13 August, 2014. The objective is to demonstrate how remotely sensed data can provide exploration targets for deposits in Canada¿s north, as well as compare and contrast results from the different sensors.
ASTER is a 14 band multispectral sensor launched by NASA and Japan¿s METI (Japan Space Systems) in December 1999. ASTER has bands in the visible to near infrared, short-wave infrared and thermal (with spatial resolutions of 15, 30 and 90 m,
respectively), and has been widely used world-wide to generate regional-scale mineral exploration targets. WorldView-3 is a 17 band multispectral sensor with a 31 cm resolution panchromatic band, 8 bands in the visible to short-wave infrared and 8
bands in the short-wave infrared, with native or collected spatial resolution of 1.2 and 3.7 m, respectively. Current US regulations will limit the spatial resolution of the SWIR sensor to 7.5 m when released.
|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. This abstract will compare and contrast the various outlined methods of remote sensing for mineral exploration in
Canada's north. these methods are "green" and can significantly shorten the discovery phase of mineral exploration.
