The Succoth Cu (-Ni, Pd) deposit is large, taxite-hosted, magmatic sulphide deposit located in the West Musgrave Province of Western Australia. Mineralisation consists of disseminated, matrix, and massive Cu-Fe sulphides and lesser Ni-Fe sulphides hosted within a mafic intrusive body. The intrusive was emplaced within a sequence of earlier Proterozoic mafic intrusives and meta-volcanics during the Giles Event (1085–1040 Ma) and subsequently ductile-deformed and strongly overprinted by hydrous alteration phases, predominantly amphiboles. An igneous architecture is presented based on contact and xenolithic relationships and internal fractionation trends in existing diamond drill holes, and the silicate and sulphide mineralogy of the host and wall rock units are detailed. Sulphide geochemistry and stable isotope data are interpreted to reflect modifications to the magmatic signature of the mineralised intrusion as a consequence of wall-rock contamination and hydrothermal overprinting. Genetic implications of different PGE chemistry between disseminated and massive sulphides in the system are discussed.
