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

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.

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.

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.

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).

Total magnetic intensity reduced to the pole (TMI RTP) image overlain on tilt-filtered (Tilt) total magnetic intensity reduced to the pole image. The image is a partially-transparent pseudocolour layer of TMI RTP, with a histogram-equalised colour-stretch, overlain on a greyscale intensity layer of the Tilt, with a histogram-equalised stretch. Cooler colours indicate lower values and warmer colours represent higher TMI RTP values. Dark tones indicate lower values and lighter tones represent higher values of the Tilt. Reduction to the pole filters magnetic anomalies to appear as if the Earth's magnetic field were locally vertical, as at the magnetic pole (assuming all magnetic sources are inductively magnetised). The tilt-angle filter produces a positive maximum over the centre of a magnetic source and is zero near the edge of the source, and is useful for tracing geological structure below variable depths of cover. Variations in the magnetic field are caused by lithological factors, principally magnetite (and/or pyrrhotite) content. This Statewide image was generated by merging many individual airborne magnetic surveys.

A subset of the NSW water bore dataset focused specifically on Cobar.

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.

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.
