Abstract: In this study, we compared traditional lithochemical s le media (soil) with hydrochemical (groundwater), biogeochemical (plant matter of mulga and spinifex), and other near-surface s le media (ferro-manganese crust), in a case study applied to mineral exploration in weathered terrain, through the critical zone at the fault-hosted Prairie and Wolf Zn–Pb (Ag) deposits in Western Australia. We used multi-element geochemistry analyses to spatially identify geochemical anomalies in s les over known mineralization, and investigated metal dispersion processes. In all near-surface s le media, high concentrations of the metals of interest (Zn, Pb, Ag) coincided with s les proximal to the mineralization at depth. However, the lateral dispersion of these elements differed from regional (several km groundwater) to local (several 100′s of meters solid s le media) scales. Zinc in spinifex leaves over the Prairie and Wolf deposits exceeded the total concentrations in all other s le media, while the metal concentrations in mulga phyllodes were not as pronounced, except for Ag, which exceeded the concentrations in all other s le media. These observations indicate potential preferential metal-specific uptake by different media. Pathfinder elements in vegetation and groundwater s les also indicated the Prairie Downs fault zone at the regional (groundwater) and local (vegetation) scale, and are, therefore, potentially useful tools to trace fault systems that host structurally controlled, hydrothermal Zn–Pb mineralization.
