Recent advances in geochemical modelling may yet breathe life into mineral exploration. Empirically based exploration geochemistry has seen few improvements in the last decade and its use as a mainstream exploration tool is in decline. The inherent complexities of geochemical thermodynamics and geochemical modelling in general have also hindered progress in the educational and academic sectors. The Predictive Mineral Discovery CRC (pmd*CRC) has formed a core geochemical modelling group as the hub of a broader Australian collaboration, and significant progress has been made on many of the problem areas. Here we demonstrate some applications of this new technology to mineral exploration in greenstone terranes, with examples of fluid-rock reaction, the role of intrusions, outflow above buried deposits, dispersion halos and forward modelling of geophysical signatures.
