It is paramount to know the geochemical footprint and heavy mineral chemistry of the various primary ore deposit types, and to compare those data with heavy mineral chemistry data in the deposit’s sedimentary catchment area. WP4 will complete the principal geological validation for the approach of this project. It will determine geochemical key parameters of heavy minerals for various deposit types, which can then be used in unknown terrains during early stages of greenfields exploration or to refine results of targeting in a more advanced stage of exploration.
