This vector file contains the location of reprocessed surveys and their acquisition parameters. These reprocessed surveys are from airborne geophysical surveys that have been submitted to the NSW government by exploration and mining companies. They have been publicly released under the NSW Mining Act 1992.

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.

In 2016, the Geological Survey of NSW (GSNSW) published a state-wide depth to basement 3D model (Robinson 2016, 2017). Since then, new geological and geophysical data have been released and used for the construction of basin-scale 3D geological models for the southern Thomson Orogen and the Sydney, Gunnedah and Bowen basins (Davidson 2019; Oliveira and Davidson 2019; Oliveira et al. 2019). The basement topography under these regions was modelled using constraints from drillholes, seismic, Seamless Geology, magnetics and gravity data. The results have now been incorporated into the updated Statewide 3D Basement Elevation Model reported herein.

The Competitive Allocation Pathway is designed to maximise the value of a suitable unallocated coal resource through a competitive process. The Department of Regional NSW’s (Regional NSW) Guideline for the Competitive Allocation of Coal (December 2020) sets out when the Competitive Allocation Pathway applies.

The isotope geochemistry database contains geochronology and geological process data managed by the Geological Survey of NSW (GSNSW). Isotopic systems / techniques are U/Pb, K/Ar, Ar/Ar, Rb/Sr, Pb/Pb, Re/Os, Sm/Nd, Lu/Hf and stable sulfur, carbon, oxygen and hydrogen. The database stores location and sample collection information, lithological description, analytical and interpretation information for geological samples in New South Wales. The database includes links to stratigraphic unit, mineral occurrence and drill hole data. Some fields are controlled by look up tables.

EM-IP-MT 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.

Gazetted Reserves which exclude mining and/or exploration operations. Specifically for use in the Lightning Ridge and White Cliffs areas.

Identifies Opal Prospecting Areas for the State of NSW as defined by Part 10, Division 1, Section 220 of the Mining Act 1992 No. 29.

This collection contains mineral specimens from locations of economic mineral importance in NSW>

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.
