This report combines large-scale observations (i.e. remapping drill core logs and hand sample observations) and small-scale observations (petrography, whole rock geochemistry, isotopes coupled with argon geochronology on hydrothermal alteration) with chemical attributes of the fluid(s) responsible for alteration and mineralization. The knowledge gained from this research has highlighted the potential of far-field vectors to identify Cu-PGE mineralization in the richly mineralized Sudbury mining district.
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. The TGI4 Ni-Cu-PGE project Podolsky activity was designed to constrain the nature, origin, significance and relevance of the alteration in the context of the SIC mineralization and exploration. Thus, alteration-specific mineralization can be fully characterized and chemically fingerprinted which could be used to provide criteria for vectoring towards mineralization in other, more complex areas. The footwall environment of the Sudbury Igneous Complex (SIC) hosts high-grade Cu(-Ni)-PGE deposits which have in recent years become prime exploration targets due to increases in metal prices and occurrence in a mature mining district. This is a release of databases.
