Abstract
<div>Sediment-hosted copper (Cu) mineral systems are important sources of base metals and critical minerals such as cobalt that are vital to delivering Australia’s low-carbon economy. In Australia, sediment-hosted Cu resources account for ~11% of the total Cu resources. Given their significance to the Australian economy, national-scale mineral potential models for sediment-hosted Cu have been developed. In addition to the potential for sediment-hosted Cu mineralisation, the uncertainty related to data availability has been examined. Three mineral potential</div><div>models derived from the combination of two mineral systems have been derived from a large volume of precompetitive geoscience data combined with mineral systems expertise, each using a different combination of input maps to assess the influence of incomplete data on the results. The mineral potential models successfully predict the location of major sediment-hosted stratiform Cu and Mount Isa-type Cu deposits while highlighting new areas of elevated prospectivity in under-explored regions of Australia, reducing the exploration search space</div><div>by up to ~84%.</div>

Purpose
National-scale mineral potential maps for sediment-hosted Cu have been developed that incorporate sediment-hosted stratiform Cu and Mount Isa-type Cu mineral systems. In addition to the potential for the copper mineralisation, the uncertainty related to data availability has been examined. The mineral potential maps were created using a mineral systems-based approach where mappable components have been used to assess the prospectivity of each system. Each mineral potential map has been derived from a large volume of multidisciplinary precompetitive geoscience data. The mineral potential maps successfully predict the location of major sediment hosted stratiform Cu and Mount Isa-type Cu deposits while highlighting new areas of elevated prospectivity in under-explored regions of Australia, reducing the exploration search space for sediment-hosted Cu mineral systems.
