Centennial Myuna Surveys

Centennial Myuna will undertake a low impact, non-intrusive geophysical exploration survey over approximately 2 weeks starting in early September 2024. Work will take place 7am to 6pm on weekdays and 8am to 1pm on Saturdays. The survey will be completed in two areas of Lake Macquarie as shown below.

This will determine the rockhead cover between the mine workings and the lakebed and identify geological features in the coal seam. The exploration program will involve a boat-towed geophysical survey.

These geophysical survey methods have been previously assessed for environmental impacts, with negligible impacts anticipated. This survey method has been previously used successfully within Centennial Myuna’s Mining Lease for surveys completed in 2020 and 2022.

Hydrographic and Magnetic surveys are commonly undertaken in marine environments, including in Lake Macquarie. Used to develop contours of the lakebed and identify geological features, an example is the monitoring of the Swansea channel, to understand depth and nature of the sediments.
