CuBAS – Structural and sedimentological reconstruction and fluid flow simulations for copper exploration in the Yeneena Basin – Paterson Orogen, WA

The Challenge

Copper deposits in sedimentary basins can lie deep and often under thick cover, which makes their exploration difficult. Integrated multidisciplinary approaches are needed to help reduce the search space and overcome the limitations of traditional surface-based methods.

Proposed Solution

This project showcases an integrated workflow combining structural restoration, stratigraphic forward modelling, and fluid flow simulation to improve exploration for sedimentary-hosted copper in the Yeneena Basin (WA). The study identified Officer Basin evaporites as a likely brine source, with sub-basin architecture and permeability anisotropy controlling fluid migration. Thermal convection and blind faults were shown to be critical for mineralisation in the Broadhurst Formation. The approach enhances predictive targeting and is applicable to other sedimentary basins.

Proposed Benefits to WA

This project enhances Western Australia’s global leadership in mineral exploration by developing advanced, integrated modelling tools that reduce exploration risk and cost. It supports more efficient discovery of copper resources critical to the clean energy transition, strengthening the state’s economic resilience and contribution to a low-carbon future.
