MinEx Cooperative Research Centre (MinEx CRC) activities will be undertaken in the Mundi Mundi Plain and surrounding areas northwest of Broken Hill. However, the MinEx CRC National Drilling Initiative will only focus on the Mundi Mineral Allocation Area MAA (Figure 1).

Current activities

Geological mapping and sampling

Rock samples will be collected from outcrops during field mapping in 2020-2021. Samples will be analysed for geochemistry, mineralogy and age dating. View more information and a video explaining geological mapping here.

Results will be incorporated into the NSW Seamless Geology Geodatabase which is available on MinView.

Low-level airborne survey in Mundi Mundi region

GSNSW and Geoscience Australia will coordinate an airborne electromagnetic (AEM) survey in the Mundi Mundi area to measure the natural electrical properties of rocks and soil to a maximum of 400 m deep. 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.

A specialist geophysical contractor will undertake the survey in March 2021. They will operate a light aircraft or helicopter flying at a height of 60 m, along east–west lines. The planned lines are around 40 km long and spaced up to 5 km apart. A map of the proposed survey area is shown below. An interactive map of the proposed survey lines will be available online in the weeks before the survey starts flying.

The data acquired will be processed and made publicly available in the second half of 2021 on MinView. If you are interested in receiving a copy of the data please email us at minex.crc@planning.nsw.gov.au.

Community information sessions

The Geological Survey of NSW is planning to hold free drop-in sessions for landholders and the wider community in Broken Hill in September 2021.

Completed activities

A reconnaissance field trip to the area was organised as part of the Uncover Curnamona Conference in 2019 (GS2019/0702). An audit and gaps study of the area followed and is available on DIGS (GS2019/1237).
