MinEx Cooperative Research Centre (MinEx CRC) activities will be undertaken across the greater Cobar region. However, the MinEx CRC National Drilling Initiative will only focus on North and South Cobar.

Current activities

There are no current field activities in the Cobar area.

Completed activities

Water sampling was conducted in May to September 2019 across the greater Cobar region. 86 samples were collected, and analysed for a range of elements, and parameters such as salinity and pH. The age of some of the water samples was determined. Results were forwarded to landholders in May 2020  and will be available on MinView soon.

The results are currently being interpreted by CSIRO researchers.

Low-level airborne survey in Cobar–Lake Cargelligo region

GSNSW and Geoscience Australia coordinated an airborne electromagnetic (AEM) survey to measure the natural electrical properties of rocks and soil to a maximum of 400 m deep in the Cobar–Lake Cargelligo area. These properties vary depending on the type of rocks and soil, and the water content and salinity. The information collected will improve our knowledge of the geology and groundwater resources of the area, which will inform mineral explorers and farmers.

New Resolutions Geophysics (NRG) was contracted to undertake the survey. A helicopter flew at a height of 60 m, with the sensor suspended 30 m below, along 116 east–west lines. The lines were typically about 55 km long and between 2.5 km and 5 km apart. An interactive map of the survey lines is shown below.

The data has been processed and is publicly available. If you are interested in receiving a copy of the data please email us at minex.crc@planning.nsw.gov.au. The data is also available from MinView.

We would like to thank the local community for their support.

Community information sessions

The Geological Survey of NSW held free drop-in sessions for landholders and the wider community in Cobar and Lake Cargelligo in April 2019.
