Elevation is a greyscale layer with a histogram-equalised colour stretch. Cooler colours indicate lower values and warmer colours represent increasingly higher elevation. Elevation is derived from 5 metre LiDAR coverage of NSW and has been resampled to a uniform 25 metre grid cell size.

Geophysics survey data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters. These surveys use uncommon techniques.

This layer shows a depth slice from a 3D resistivity model of the crust derived from an inversion of the AusLAMP NSW long period MT data.

Greyscale image of first vertical derivative (1VD) of Bouguer gravity. Darker tones indicate lower values and lighter tones represent higher values. Bouguer gravity compensates for variations in latitude, 'free-air' elevation and Bouguer correction (assuming a crustal density of 2.67 T/m³). Attention: Please ensure your version of the NSW gravity merges contains the date ‘2024-10-30’ in their filename. An update was made to remedy location errors in the initial release. Apologies for any inconvenience.

Identifies Mineral Claims Districts in the State of NSW as defined by Part 9, Division 1, Section 173 of the Mining Act 1992 No. 29. There are two current Mineral Claims Districts: Lightning Ridge Mineral Claims District, and White Cliffs Mineral Claims District.

Pseudocolour image of the ratio between uranium and thorium within the upper 20 centimetres of the ground. This image was generated using normalised input grids to avoid ‘divide by zero’ errors. Cooler colours indicate lower abundances of uranium relative to thorium and warmer colours represent the opposite. Variations in U/Th ratio are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

Wind farms dataset displays the location of wind farms in NSW. Wind Farms contain wind turbines, which can be up to 200m tall.

Gravity gradiometry data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

Greyscale image of first vertical derivative (1VD) of isostatic residual gravity (Iso-grav). The 1VD filter shows the rate of change in the isostatic gravity data. Darker tones indicate lower values and lighter tones represent higher values. Attention: Please ensure your version of the NSW gravity merges contains the date ‘2024-10-30’ in their filename. An update was made to remedy location errors in the initial release. Apologies for any inconvenience.

The NSW Government has ruled out considering a significant proportion of the state’s coal regions for proactive release under the Strategic Release Framework for Coal and Petroleum Exploration. In these mapped areas, new coal exploration can continue to occur directly adjacent to an existing coal title, if an exploration licence applicant meets approval requirements. If a coal exploration licence is granted, an operator is not permitted to access the land unless they have an access arrangement with the landholder. The grant of a coal exploration licence is not a guarantee of mining. An operator would still need to obtain development consent under the planning framework.
