The petrophysics dataset contains petrophysical (rock physical properties) data acquired by the Geological Survey of NSW. It stores measurements of samples and mapping sites collected under the Field Observations database, including from drillholes. It currently covers the following techniques: mass properties, electrical, radiometric, seismic rock physics, magnetic susceptibility and magnetic remanence. It contains raw readings and calculated results, from field and laboratory environments. Vector and tensor magnetic properties (remanence and anisotropic magnetic susceptibility (AMS)) are oriented to in-situ (geographic) and fold-corrected (stratigraphic) co-ordinates where sample and bedding orientation are known.

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.

Many airborne magnetic/radioelement surveys have been acquired by the NSW government through the NSW Exploration, Discovery 2000 and New Frontiers Initiative funding. Others have been acquired jointly with Geoscience Australia (formerly AGSO). Contained within this vector file are details on each of the surveys and some acquisition parameters, which will help locate survey data stored digitally. Not all of these surveys have both radioelement and magnetic data.Some project areas have grids that have been merged from private exploration company data (that are open file). These are attributed as "private" exploration company data in the shapefile. The information contained in this publication is based on knowledge and understanding at time of writing (December 2016). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date.

Spatial data set showing Mining Divisions within New South Wales. Each Mining Division has a Mining Registrar. A title is considered to be within the Mining Division in which the most northeasterly portion of the title lies.

This layer shows the boundaries of ground gravity surveys acquired by the NSW government. Details on the spacing and age of the gravity station within each project area are in the attributes.

Areas restricted from mining or exploration. Reserves emplaced by external agencies or authorities. If a lease application covers part or all of one of these areas, it must be referred to and approved by the agency which created the restriction.

Drillhole sample geochemistry that has been reported by title holders to the department as part of the mineral exploration reporting requirements. The data is provided annually in the form of exploration data files and stored with the relevant tenement report in DIGS. Data mining of digital exploration data files stored in DIGS is largely complete for the period 2001 to present. Data mining continues for DIGS reports earlier than 2001 using OCR (optical character recognition) software to convert raster data into digital files for loading. Validation of data is an ongoing process. Data available to the public and industry is restricted to DIGS open file reports.

Geological Maps at the 1:100 000 scale for all of NSW. This data has been synthesised into the 1:1 500 000 scale map of NSW, which forms the base layer of Minview.

Marine protected areas are parts of the NSW marine estate managed to conserve marine biodiversity and support marine science, recreation and education. The NSW system of marine protected areas includes: marine parks – six multiple use marine parks cover around one third (approximately 345,000 hectares) of the NSW marine estate aquatic reserves – 12 aquatic reserves cover around 2,000 hectares of the NSW marine estate national parks and nature reserves – include around 20,000 hectares of estuarine and oceanic habitats.
