Presentation Abstract:
Mineral Exploration Using Multispectral Satellite Imagery
Multispectral satellite dataset analysis is a reliable and effective mineral exploration technology. The sun’s earth-reflected radiance is captured by satellites and processed to obtain bottom-of-the-atmosphere reflectance. Each pixel in an image contains a spectral blend of elements, molecules, minerals, and other components. Images can routinely contain up to 100 million pixels.
Extracting specific mineral spectra from a pixel can be roughly compared to collecting partial fingerprints from each pixel-sized “crime” scene and matching them to well-defined reference imprints in a spectral database. For a geologist, the reference imprints are laboratory-generated rock and mineral spectra maintained in spectral libraries by organizations like the US Geological Survey. The idea is to obtain, from each pixel, abundance estimates for one or more selected target minerals and related pathfinders. The economic objective is to identify exploration areas consisting of high-abundance pixel clusters.
The presentation will start with a brief review of the spectral analysis process and free satellite imagery options; followed by a field verification example to demonstrate the reliability and precision of the process. Then, actual projects will be described. The spectral analysis workflow generates spectacular images, sometimes with a target definition of a specific pixel.
Presenter Bio:
Richard Boulay, B.SC.
Rick Boulay holds a Bachelor of Science degree in Geology from Carleton University. He has worked continuously for over 50 years in the minerals and hydrocarbon industries as an exploration geologist, mining analyst, project financing banker, and public company executive. He has worked extensively in Canada, the western United States, Australia, Mexico, Peru, Argentina, Uruguay, Paraguay, Tanzania, and Kenya. As a geologist and prospector, he develops and directs exploration projects using multispectral satellite datasets to generate exploration targets.
