The Re-Os isotope data indicate different crustal sources for the ore-forming elements at the Grasberg Cu-Au deposit and support a model in which gold is derived from sedimentary protoliths, that may have been pre-enriched by sedimentary processes. The gold derived from these sources is concentrated by magmatic/hydrothermal systems.
