The East Riverina Mapping Project provides up-to-date data to aid mineral exploration and to inform regional land-use decisions. Land-use pressure has increased in the east Riverina region, particularly in the new residential zones around Wagga Wagga and along the Hume Highway corridor. The latest Wagga Wagga 1:250 000 geological map was released in 1966 before the development of modern mapping and data collection techniques that allow interpretation of geology below deep alluvial cover.

The project area is in the central Lachlan Orogen and includes the Wagga tin or metamorphic belt, and the Gilmore and Kancoona fault zones. The area is prospective for a range of deposit-styles, including intrusive tin-tungsten deposits (e.g. Ardlethan), orogenic gold and copper-gold porphyry systems.

Systematic field mapping is integrated with specialist studies such as mineral systems, geochronology (with Geoscience Australia), palaeontology, spectral analysis, geophysical modelling, reinterpretation of seismic lines, 3D modelling of geology and fluid flow, and hydrogeochemistry (with CSIRO).

Products will include 1:100 000 (or better) geological mapping that will be incorporated into statewide digital geoscience datasets, annual technical and specialist reports, mineral prospectivity assessments and 3D models.
