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).

Operating mines in NSW is a small subset of sites taken from the NSW Mineral Occurrence dataset which represent an active mining operation. An operation is a deposit or group of deposits of similar style within the same district, operated by a common operator. Generally an operation will have a single common processing plant. An operation is considered to be ‘operating’ (active mine) if ore is being produced and a royalty paid from at least one of its deposits. The Operating status of each deposit is maintained in the MetIndex database and based on the following definition. Operating Mines Layer: For the purpose of an operating mines layer for metallic minerals, an operating mine is a mining operation where production is on a continuous or intermittent basis. Operation: An Operation is a deposit or a group of deposits of a similar style within the same district, operated by a common operator. Generally an operation will have a single common processing plant. Operating status: Operating status is continuous where there is reported production at least twice in a 12 month period, operating mines with less reported production are classified as intermittent.

This map layer shows the locations of in-stream water monitoring stations used by coal mining companies to monitor water quality in the Upper Hunter catchment. This information is provided by the coal companies as part of the Upper Hunter Mining Dialogue in cooperation with NSW Minerals Council and the community. A different coloured symbol is used for each coal company.

This data set is modified from the Australian Geological Provinces Database (Geoscience Australia) and contains descriptions and spatial extents of the fundamental geological elements of NSW. Province types include sedimentary basins, tectonic provinces such as cratons and orogens, igneous provinces, and metallogenic or mineral provinces. At its simplest, a province may describe a sedimentary basin and its fill (e.g. the Sydney Basin). However, provinces may also be defined by a complex history of tectonics, metamorphism, magmatism, or metallogenesis. Provinces outlines, including their subsurface extent, are compiled at around 1:1 million scale. Descriptions of the provinces include age and geological history, parent-child hierarchy, constituent stratigraphic units and relations to surrounding provinces.

AEM curtains are a set of cross-sections generated using geophysical inversion to convert AEM data to conductivity (m/S) versus depth below surface (m). These data represent the conductivity of soil and rocks to a depth of about 400 m. A pseudocolour-stretch has been applied to the data. Blue represents low conductivity values and red represents high values. The colours vary due to; (1) natural variations in the electrical properties of soils, rocks, minerals and groundwater, (2) man-made structures, radio-transmissions and lightning strike and (3) AEM system artefacts.

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 is the coal subset of the NSW drilling dataset available from Geoscientific Data Warehouse. The drillhole data has been compiled over time from various sources including mineral exploration reports and departmental records.It provides drill collar information for coal drillholes and associated data including classification of drilling purpose, drill type, licencee/driller information, date the hole was drilled, depth of hole drilled and references. This data is part of the New South Wales Geoscientific Data Warehouse (NSW GDW) series.

The coal seam gas drillholes dataset stores information about CSG sites within NSW. The dataset has been developed to record summary data on CSG exploration and development drilling for holes drilled in New South Wales. The dataset contains summary information about each drillhole such as location, total depth, azimuth/dip, wireline logs, core availability and library location and DIGS references. This data is part of the New South Wales Geoscientific Data Warehouse (NSW GDW) series.

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