The main mineralization event (Fimiston) in the Kalgoorlie gold camp (~2,300 t Au; Yilgarn craton) formed from Au-Te-rich, magmatic-hydrothermal fluids associated with mantle-derived magmas localized to ca. 2675 Ma D2b zones of transtension. This early mineralization event was overprinted by D2c contractional deformation and Oroya lodes at ca. 2665 Ma and by D3 dextral shearing and Mt. Charlotte mineralization at ca. 2650 Ma. This refined framework and genetic model for the camp suggests that the bulk of gold endowment formed at ca. 2675 Ma, prior to the late-stages of cratonization in the Yilgarn craton, from a metasomatized lithospheric mantle source.
