The government will consider releasing a limited number of new areas for coal exploration under the Strategic Release Framework for Coal and Petroleum Exploration. Under this Framework, the government may refer an area to the Advisory Body for Strategic Release (ABSR). If a coal exploration licence is granted, an operator is not permitted to access the land unless they have an access arrangement in place with the landholder. Release of an area for exploration is not a guarantee of mining. An operator would still need to obtain development consent under the planning framework.

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.

AEM data has been acquired by the NSW government through NSW Exploration, Discovery 2000 and New Frontiers Initiative funding. Contained within this vector file is the location of AEMsurveys and acquisition parameters. The information contained in this publication is based on knowledge and understanding at time of writing (February 2017). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date. The information contained in this publication may not be or may no longer be aligned with government policy nor does the publication indicate or imply government policy.

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 Geological Survey of NSW developed a Seamless Geology of UTM Zone 56 during 2014 as part of a project to develop a seamless vector geology dataset of the best available geological mapping data covering the whole of NSW.The overarching aims of the Statewide Seamless Geology Project were to: (i) compile the different original scales, formats and rock unit naming conventions into a consistent, statewide format; (ii) edge-match the geology across existing map sheets; and (iii) interpret the basement geology under cover. The resulting geodatabase comprises a series of layers which include: (i) solid basement geology; (ii) cover rocks (defined as undeformed and unmetamorphosed); (iii) Mesozoic igneous rocks; and (iv) Cenozoic sedimentary and igneous rocks. The project was divided into 3 major stages corresponding to the UTM zones which divide New South Wales. This dataset includes the seamless geology layers from the NSW portion of UTM Zone 56 (ie.east of 150 degrees longitude to the coast).

This layer shows the boundaries of each airborne gravity survey acquired by the NSW Government. Details on the spacing and age of the gravity data within each project area are in the attributes. The information contained in this publication is based on knowledge and understanding at time of writing (April 2017). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date. The information contained in this publication may not be or may no longer be aligned with government policy nor does the publication indicate or imply government policy.

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

Pseudocolour image of the ratio between uranium and potassium 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 potassium and warmer colours represent the opposite. Variations in U/K ratio are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

Pseudocolour image of the ratio between thorium and potassium 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 thorium relative to potassium and warmer colours represent the opposite. Variations in Th/K ratio are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.
