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. A new approach to characterizing and classifying mineral deposits based on whole rock geochemistry is currently being developed jointly by the mineral exploration industry, two universities and the GSC. The project is focused on the correct/best metric to use and a decision tree approach to ore deposit classification, amongst others. Research done to date, shows that this approach has successfully identified a wide range of mineral deposit types including porphyry, lode gold, PGE, skarn, sedimentary hosted massive sulphides, volcanic hosted massive sulphides, Mississippi-type lead-zinc deposits. Geochemical data of unknown metallogenic affinities can be classified and existing classifications can be enhanced/re-defined. The results of this project will assist in advanced mineral exploration programs
