The NSW Government has ruled out considering a significant proportion of the state’s coal regions for proactive release under the Strategic Release Framework for Coal and Petroleum Exploration. In these mapped areas, new coal exploration can continue to occur directly adjacent to an existing coal title, if an exploration licence applicant meets approval requirements. If a coal exploration licence is granted, an operator is not permitted to access the land unless they have an access arrangement with the landholder. The grant of a coal exploration licence is not a guarantee of mining. An operator would still need to obtain development consent under the planning framework.

The Competitive Allocation Pathway is designed to maximise the value of a suitable unallocated coal resource through a competitive process. The Department of Regional NSW’s (Regional NSW) Guideline for the Competitive Allocation of Coal (December 2020) sets out when the Competitive Allocation Pathway applies.

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.

Identifies areas in the Lightning Ridge Mineral Claims District and White Cliffs Mineral Claims District where the Department has declared reserves over which mineral claims cannot be granted, or can only be granted provided that special conditions are met, as defined by Part 17, Division 2, Section 367 of the Mining Act 1992 No 29.

The New South Wales 1:1 500 000 scale geology has been compiled from numerous geological maps and regional geological synthesis datasets from the Geological Survey of New South Wales and Geoscience Australia. As part of a project to produce a surface geology map of Australia, Geoscience Australia (Liu et al. 2005) undertook substantial simplification and generalisation of these datasets to produce a seamless geology dataset of New South Wales at 1:1 000 000. This 1:1 000 000 geology dataset has been further simplified, generalised and updated by the Geological Survey of New South Wales to produce the present data set at 1:1 500 000

Geothermal gradient model (2023) created by Geognostics with support from government and industry. The geothermal gradient describes how temperature increases with depth inside the Earth. It is expressed in degrees Celsius per kilometre (°C/km). The linear geothermal gradients are from the top of SEEBASE to the surface. These were calculated using the combined heat-flow contribution of multiple crustal heat sources including upper mantle, radiogenic upper crust, and sediment thickness. The highest calculated geothermal gradients are generally related to areas interpreted to be underlain by granitic intrusions in the basement. The composition and heat production characteristics of the granites are largely unconstrained by analyses

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.

An index of 1:250 000 map sheets covering NSW. The index shows maps where the total statewide geophysics package has been clipped and re-imaged to enhance colour stretch for the local regions. Each map sheet suite contains grids and images for up to 40 different layers, including: - Total Magnetic Intensity (TMI) - TMI Reduced to the Pole (RTP) - First Vertical Derivative (1VD) of TMI RTP - Second Vertical Derivative (2VD) or TMI RTP - Tilt Angle Filter of TMI RTP - TMI RTP and TMI RTP Tilt composite - Analytical Signal (AS) of TMI RTP - 250m and 500m Upward Continuations (UC) of TMI RTP - 1VD of TMI RTP UC products - Potassium percentage (Kperc) - Thorium parts per million (Thppm) - Uranium parts per million (Uppm) - Potassium-Thorium-Uranium ternary (KThU) - Zero mean normalised Kperc - Zero mean normalised Thppm - Zero mean normalised Uppm - Dose Rate - Uranium squared divided by Thorium (U2/Th) - Thorium divided by Potassium (Th/K) - Uranium divided by Potassium (U/K) - Uranium divided by Thorium (U/Th) - Airborne & Ground Bouguer gravity - Airborne & Ground Bouguer gravity and TMI RTP Tilt composite - Airborne & Ground Bouguer gravity 1VD - Airborne & Ground Isostatic gravity - Airborne & Ground Isostatic gravity and TMI RTP Tilt composite - Airborne & Ground Isostatic gravity 1VD - Digital Elevation Model (DEM) - Terrain colour stretch - Pseudocolour colour stretch - Greyscale colour stretch
