This paper provides an update on the development of mineral potential models for orogenic, epithermal and intrusion-related gold (IRG) mineralisation for onshore Zealandia. GNS Science has adopted a mineral systems approach to define parts of the mineralisation process that are critical to ore formation which are then mapped from publicly available geoscience data and combined to form a model of mineral potential. The project capitalises on the release of new geological, geophysical and geochemical digital data sets as well as the recent modelling for clean technology minerals (Morgenstern et al., 2018) and aggregate potential (Hill, 2018) using a similar approach and data sets at a national-scale. A wealth of knowledge about some specific mineral systems in New Zealand and well-studied mineral deposits provides an excellent framework for mineral potential modelling. The preliminary results from this study illustrate examples of regions where gold, silver and critical elements such as tungsten, bismuth, antimony, and molybdenum are more likely to be found in economic quantities. The study has also identified key data sets which can be collected or created from existing data that would improve future iterations of mineral systems modelling.
