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.

In 1994 the Lightning Ridge Mining Board determined that the title ‘Preserved Fields’ would be applied to older mining areas which would not be returned to their previous land use, adopting less strict rehabilitation standards.

Survey Pegs used to mark out Mineral Claims in the Lightning Ridge and White Cliffs areas of NSW, Australia.

This vector contains the boundary of the MinEx Collaborative Research Centre (CRC) Cobar Airborne Electromagnetic (AEM) surveydivided into three areas. This division is based on the flight line spacing which varies from 2.5 to 5.0 km. This survey was a collaboration between the Geological Survey of NSW and Geoscience Australia.

Identifies areas in the Lightning Ridge Mineral Claims District and White Cliffs Mineral Claims District where the Department has declared reserves over which mineral claims cannot be granted, or can only be granted provided that special conditions are met, as defined by Part 17, Division 2, Section 367 of the Mining Act 1992 No 29.

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 refined and the results have now been incorporated into the updated state-wide depth to basement 3D model reported herein.

In 2023, the Geological Survey of NSW (GSNSW) engaged Geognostics to perform a review and update of the previous OZ SEEBASE 2021. Previous SEEBASE® studies of NSW basins undertaken by Frogtech Geoscience were undertaken over 15 years ago, and significant new data have been acquired since that time (drillholes, gravity, magnetics, seismic, etc.), along with on-going research and consolidation of statewide interpretations undertaken by the Geological Survey of NSW (GSNSW; i.e., the Seamless Geology Map of NSW by Colquhoun et al., 2022).

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.

This layer shows the boundary of the AusLAMP NSW survey and the station locations. Data were acquired by a collaboration between GSNSW and Geoscience Australia. Data were used to create a 3D resistivity model of the crust from 10 km depth to 200 km depth.
