Discovering buried copper porphyry mineralization : geochemistry and indicator minerals in till / [by] A. Plouffe and T. Ferbey. : M183-2/7680E-PDF

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. The first part of our study demonstrated that sediments deposited by glaciers contain certain type of minerals and metals that are indicative of metal enrichment in the underlying bedrock. Such enrichment, if significant enough, has the potential to become a mine. Therefore, the presence of those minerals and metals in the glacial sediments can help find mines. We have tested this hypothesis by looking at the composition of glacial sediments in a region where there is no mine. Our results indicate that in two zones, certain minerals enriched in copper and gold found in glacial sediments could be indicative of undiscovered mineralization in rock. This study was completed as part of the Targeted Geoscience Initiative-4 of the Geological Survey of Canada.
