The Geological Survey of Victoria welcomes delegates to the International Mining and Resources Conference (IMARC) 2022

Victoria is a world-class gold province. The central gold province alone has produced 2500 t Au (~80 Moz Au). Results from the Geological Survey of Victoria’s Gold Undercover (2006-2009) initiative estimates that the undiscovered gold endowment of the northern parts of Victoria suggest that there may be an estimated 75 Moz Au yet to be discovered. The 24 Gold Undercover reports and data sets are free to download.

Critical minerals

Victoria has world-class mineral sand deposits that contain demonstrated resources of titanium, zirconium and rare earth elements. There are also other opportunities throughout regional Victoria, such as copper, antimony, high purity alumina and silica, in addition to promising early-stage mineral exploration for other critical technology minerals.

The Victorian Government has launched the ‘Developing Victoria’s Critical Minerals’ initiative to understand the state’s capacity to derive value from the potential production and processing of critical minerals that underpin the global energy and technology transition.

State Drill Core Library

Based at Werribee, the State Drill Core Library is an invaluable geoscientific asset, allowing rock and mineral samples to be studied and reanalysed at minimal/no extra cost.

The collection includes rock samples from minerals drill holes, petroleum wells, groundwater bores, government stratigraphic and co-funded industry drilling, geotechnical/infrastructure drilling, extractive drill holes, coal bore holes, geothermal drill holes, government mapping programs as well as hardcopy reports and maps.

Visits are by appointment only. To arrange please email or phone +61 3 9623 1503.


GeoVic is a free online mapping portal. You can build your own earth resource related maps, perform searches and access data, using a huge range of data sources.

Search across mineral, petroleum and extractive industry tenements. Look at geological maps and interpretations at various scales. Find land-use data, aerial photography as well as gravity, magnetic and radiometric images, borehole and well data. You can also access surface geochemistry results, mines and mineral occurrences and renewable energy data (eg solar, geothermal and wind).

There are also useful instructions to assist with your search.

Victoria's exploration and mining performance

Published annually, the Earth Resources Sector Indicators (ERSI) report series captures the performance of the earth resources sector in Victoria.

3D geological models of the state

3D geomodelling can be a powerful aid to exploration. The Geological Survey of Victoria uses a multidisciplinary approach to building 3D models. Multiple geoscientific datasets are integrated to increase the likelihood of a realistic representation of the structure of the rocks and sediments in the subsurface on a regional scale.

More information about the various Victorian models can be found at the 3D geological modelling page.

Otway Basin Airborne Gravity Survey

An airborne gravity, gravity gradiometry and magnetic survey has been undertaken as part of the Victorian Gas Program, using CGG’s FALCON® airborne data acquisition system.

The survey was acquired using two small aircraft that were flown out of Warrnambool Airport. The surveyed region includes approximately 16 000 km2 of the Otway Basin in Victoria, stretching from the edge of the Otway Ranges to the South Australian border, and from south of the Grampians to approximately 18 km offshore.

For more information see the report Full Spectrum FALCON® airborne gravity and aeromagnetic survey Otway Basin Victoria.
