Ground surveyed gravity 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 NSW Mine Reuse project investigated the occurrence of critical metals in mining waste material. It involved a preliminary geochemical and mineralogical characterisation study across multiple metalliferous and coal sites on various waste material types, aiming to identify subsequent secondary prospectivity opportunities. The study was completed in collaboration between the Geological Survey of NSW, the Sustainable Minerals Institute at The University of Queensland, Geoscience Australia and RMIT University. The program consisted of hand-auger drilling and sample collection from various waste sources, including tailings, waste rock, slags, coal rejects and fly ash. Each sample then underwent a 48-element geochemical analysis, with targeted mineralogy and mineral chemistry conducted on selected samples to better understand the distribution of elevated critical elements.

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).

AEM 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 AEMsurveys and acquisition parameters.

The NSW Government has acquired hyperspectral data to aid geological interpretation. The location of hyperspectral coverage is contained within this layer. 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 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.

The Central NSW 10 metre grid package is a dataset containing best available open-file geophysical data spanning twelve 1:250,000 geological mapsheets, from Cobar in the northwest to Bathurst in the southeast. Available within the package are merged grids and high resolution imagery providing excellent geophysical coverage of the region. Gridded products include: • Digital Elevation Model (DEM) • Total Magnetic Intensity (TMI) • Total Magnetic Intensity Reduced to The Pole (TMI RTP) • Total Magnetic Intensity Reduced to The Pole First Vertical Derivative (TMI RTP 1VD) • Total Magnetic Intensity Reduced to The Pole Second Vertical Derivative (TMI RTP 2VD) • Total Magnetic Intensity Reduced to The Pole Tilt Angle Filter (TMI RTP Tilt) • Potassium Percentage (Kperc) • Thorium Parts Per Million (Thppm) • Uranium Parts Per Million (Uppm) • Radiometric K-Th-U Ternary (KThU) • Radiometric Dose Rate (Dose) • Thorium divided by Potassium (ThdivK) • Uranium divided by Potassium (UdivK) • Uranium divided by Thorium (UdivTh) • Uranium Squared divided by Thorium (U2divTh) • Isostatically Corrected Bouguer Gravity (Iso Grav) Images for each grid are also available, with the addition of: • DEM (Terrain) • TMI RTP overlaid on TMI RTP Tilt • Iso Grav overlaid on TMI RTP Tilt
