Greenstone holistic mineral systems approach to mineral exploration as a tool for developing targeting criteria, particularly for Ni and Au (McCuaig et successions developed after c. 3000 Ma show a complex al., 2010). In this review, examples from the Kambalda district in the history of juvenile crust generation and crustal Eastern Goldfields region illustrate how the size, distribution and reworking. There are at least three periods of greenstone- concentration of Au and Ni deposits are controlled by factors from related magmatism in the Yilgarn Craton. The earliest the craton to the regional scale, down to the deposit cluster and recognised greenstone development consists of volcanic individual deposit scale. While there has been little recent, regional- scale work on Yilgarn VHMS deposits, comparison with similar and sedimentary successions deposited between c. 3000– terrains in Canada suggests that the fundamental controls on Ni 2900 Ma.
