ProgramTargeted Geoscience Initiative (TGI-4), Mafic-Ultramafic Ore Systems
The Ni-Cu-PGE-Cr Ore Systems project is one of six national minerals projects in the Geological Survey of Canada¿s Targeted Geoscience Initiative (TGI-4) geoscience program with a mandate to employ public geoscience in the development of new geoscience knowledge and techniques in support of more effective exploration for buried ore deposits (Villeneuve, 2011). Nickel-copper-platinum group element (PGE) deposits are key exploration targets given high precious metal prices. These ore deposits occur in highly variable geologic settings with complex geochemical and mineralogical and geophysical signatures that challenge successful exploration, particularly in the deeper, or covered parts of established and emerging terranes.
We focus on data-rich established and emerging mining camps in Canada to optimize exploration-related geoscience knowledge with national district- and deposit-scale studies in selected areas (see Ames and Houlé, 2011). A multidisciplinary approach is focussed on improving the geological knowledge of the ore environments by determining footprints of fertile ore systems and better vectors towards their mineralized parts in high-magnesium ultramafic to mafic systems, with a report by Houlé et al., this volume (42); and hydrothermal-magmatic copper-PGE-rich systems, the subject of this paper. This project will also provide an opportunity to acquire knowledge on less understood, and mostly underexplored deposit types, such as the orogenic nickel-copper systems that host the Giant Mascot and Turnagain deposits in British Columbia.
This contribution highlights research activities within the Magmatic-hydrothermal Cu-PGE subproject carried out in collaboration with provincial and territorial governments and agencies, academia and the exploration and mining sector.
