Abstract: The Riwaka Complex is an elongate mafic-ultramafic intrusive body, about 50 km long and up to 6 km wide, that is partly disrupted by faults. Its intrusion age is late Devonian (366 Ma) and it is dominated by pyroxene, olivine and hornblende-rich mafic and ultramafic units. In the 1970s, exploration for Ni-Cu included stream sediment, rock chip and soil geochemical sampling, ground magnetic surveys and drilling of 33 shallow (
