Description:
This one-day short course will share recent advances in drift exploration principles in complex glacial terrain and methodology development in exploration for various commodities. Since playing a key role in the discovery of the Lac de Gras diamond field, indicator mineral methods have since expanded to explore for polymetallic base and precious metal deposit types, and associated alterations. These mineral exploration methods rely on sampling of sediments such as glacial and stream sediments, and detection of mineral deposit pathfinder elements and indicator minerals glacially eroded, entrained, transported and deposited down-ice. This short course will address how these exploration methods are part of a spectrum of clastic sediment-based methods that range from boulder tracing to detection of detrital debris or their weathering products by chemical analysis of C-horizon soils and sediments. The short course will consist of presentations by some of the most experienced practitioners in the field, representing government, academia and industry.
