Project activity Mineral Potential Mapping
Supporting mineral exploration in Australia.
Mineral systems describe all the physical and chemical processes that are necessary for a mineral deposit to form. Our understanding of Australia’s mineral potential is based on many different types of geoscience data that are used to map these processes, combined with decades of mineral systems expertise. Mineral potential mapping brings this data and expertise together to predict which areas of Australia have higher potential for different mineral systems to occur.
The aim of the mineral potential mapping study is to better understand key mineral systems in Australia and predictively map their potential. This narrows the search space and reduces the risk of exploration for industry. This is particularly important in unexplored or underexplored regions of Australia, including in areas covered by thick layers of regolith. It also supports the search for resources such as copper, zinc, and rare earth elements, which are critical for Australia’s transition to net zero.
As part of the Exploring for the Future program, mineral potential maps are being produced for a range of mineral systems, including:
- carbonatite-related rare earth elements
- sediment-hosted base metals (zinc, lead and copper)
- alkaline rocks-related rare earth elements
- iron-oxide copper gold mineral systems.
These maps provide a guide for mineral explorers on the most prospective parts of Australia and support exploration for commodities, including critical minerals.

Objectives
The national mineral potential mapping study aims to:
- improve our understanding of the processes involved in the formation of different mineral systems
- reduce the search space for mineral explorers by evaluating the potential for mineral systems of high interest
- identify new regions for mineral exploration, including under cover.
What are we doing?
As part of the mineral potential mapping study we are compiling a wide variety of multidisciplinary geoscience data, including geology, geophysics, and geochemistry. We are comparing these data to known mineral deposits to help us better understand the complex processes involved in their formation. We can then use this understanding to predict where similar types of mineral deposits might form.
As well as providing new information on which datasets are the most informative for predicting mineralisation, study results provide a guide for mineral explorers on the most prospective parts of Australia for different mineral systems. This supports exploration for new resources such as copper, zinc, and rare earth elements, which are critical for Australia’s transition to net zero.
Outputs
Important to know
All data produced by Geoscience Australia, including the data from this study, will be made publicly available through the Exploring for the Future Data Discovery Portal after quality assurance has been performed.
