Origin of Material: This standard was made using material provided by Quandra FNX Mining Ltd and SGS Minerals Services. The material is from project areas within the confines or peripheral to the Sudbury Structure and the associated 1.85 billion year old Sudbury Igneous Complex; located approximately 400 km north of Toronto, in close proximity to the City of Greater Sudbury, northeastern Ontario, Canada.
Mineral and Chemical Composition: The vast bulk of sulphides in the Sudbury ores consist essentially of varying proportions of pyrrhotite, chalcopyrite and pentlandite with varying amounts of other Cu-, Ni-, Co-, PGM-bearing minerals and gold.Major element chemistry data from 12 of the labs has been compiled and certified. Uncertified summary statistics for trace element data are set out in the appendix.
