Mineral deposits of NSW
New South Wales has a rich endowment of mineral resources including world-class deposits of coal, gold, copper, lead, silver, zinc and mineral sands.
The Geological Survey of NSW studies the nature and distribution of the Earth's naturally occurring mineral commodities (such as gold, copper, clay, limestone, or construction materials) and presents this information in the form of metallogenic maps, reports and databases. The data and reports underpin assessments of mineral potential for use by the mining and exploration industries and for landuse advice.
Information on mineral deposits and occurrences is stored in a corporate mineral deposit database named MetIndEx. This database contains over 29,000 records and is regularly updated with new resource information. Information held in MetIndEx can be accessed through the MinView application on the internet.
Commodity reviews of metallic and industrial minerals are also being progressively undertaken, with a focus on new mineral opportunities for New South Wales.
Information on mineral deposits and occurrences is available through:
- Metallogenic explanatory notes
- Metallogenic maps
- Mineral commodities of NSW
- Mineral exploration highlights
- Advanced mineral projects and exploration highlights map
- Mineral Resources project maps
- Scientific papers and publications
Mineral Systems of NSW Project
The aim of the Mineral Systems of NSW Project (MinSysNSW) is to identify and document the key mineral systems across NSW. The project is building on the metallogenic mapping program which documented more than 20,000 mineral deposits and occurrences covering all of the state's major basement outcrop areas.
The project is providing:
- statewide synthesis and dating of mineral deposits
- systematic classification of deposits
- recognition of large mineral systems at a regional scale
Initial inputs include:
Metallogenic Map of NSW project
The Minerals System (MinSys) team is developing a metallogenic map of NSW under the Mineral Systems of NSW project. It will use the recently released 1:3 million scale geological map as a base and will show the distribution of major mineral deposits as key mineral systems identified in the Mineral Systems Classification (Version 4). Mineral deposits are being displayed according to commodity and size criteria. This map will synthesize much of the dating work carried out by the MinSys team and is the initial step in an investigation of the timing of metallogenic events in NSW. This should allow the targeting of individual deposit types for further studies.
Auscope National Virtual Core LibraryThe AuScope National Virtual Core Library (NVCL) is a collaborative federal and state government program aimed at using CSIRO HyLogger™ spectroscopic drill core scanning technology to generate digital information on rock, ore and alteration minerals in drill core. The information will be stored in a state-based network of digital core libraries which will provide digital assay, high resolution hyperspectral data and corresponding photo-logs of drill holes via the web. This will allow core to be viewed remotely and increase access for the exploration industry and for researchers.
Broken Hill Exploration Initiative
Through the NSW government New Frontiers initiative, new exploration methodologies and techniques are applied to the geology of Broken Hill and its environs to encourage exploration investment at Broken Hill. A number of projects lie under the large umbrella of the Broken Hill Exploration Initiative. One of these is the Broken Hill Interpretive Mapping Project which aims to produce a revised stratigraphic map based on the latest geophysics and existing detailed GSNSW lithological mapping. The project will extend under cover and into Neoproterozoic sequences which surround the Curnamona Craton rocks. The interpretation will include regional structural components and use the latest stratigraphic nomenclature based on modern age dating.
