URL: https://geoscience.data.qld.gov.au/dataset/cr136135 In 2019, the Geological Survey of Queensland (GSQ) commenced the New Economy Minerals Initiative (NEMI), a 5-year program aiming to build up a comprehensive systematic physical and virtual reference collection of samples and associated geological data characterising signatures and footprints of the major mineral systems and their key constituent deposit types and styles in the Mount Isa Province, Queensland (the so-called Reference Collection project). The initial phase of the project was funded under the Queensland Government's Strategic Resources Exploration Program (2017-2021), which is extended into NEMI-2 (2022-2024) Program. This Reference Collection project was planned out to be implemented in several stages, including: - Acquisition of drill core and samples representative of ore and mineralisation from major IOCG, Pb-Zn-Ag and Cu-Au deposits, now permanently housed at the John Campbell Miles drill core facility in Mount Isa - Continuous core scanning using hyperspectral (HyLogger) and X-ray core scanning instruments (Minalyzer, TruScan - targeted campaigns) on the drill core housed at our drill core facility, along with an expanded sample collection provided by the industry partners (HyLogger and Minalizer data in this data release) - Extending a systematic collection of multi-element whole-rock and mineral geochemistry data (Multi-element whole-rock is included this data release; mineral geochemistry in the next data release) - Collection of integrated in situ micro-analytical datasets and imaging to enable more meaningful interpretation of the data, including data integration across different scales (macro to micro). This will include micro-analytical techniques, such as SEM, TIMA, EPMA, LA-ICP-MS and MicroXRF (MAIA), that are required to characterise host rocks, alteration hellos and importantly the endowment of both base-metals and critical metals (initial data in the next data release).

URL: https://geoscience.data.qld.gov.au/dataset/mr009629 The sixteenth edition of Queensland mineral, coal and petroleum operations and resources map was updated in January 2014. The Map shows the Major mining projects and mineral resources under the categories of Metals, Industrial minerals and rocks, Gemstones and Mineral sands. The Map also shows the Major coal and petroleum operations and resources under the categories of Coal, Conventional Petroleum, Coal Seam Gas, Oil Shale, Pipelines and LNG. The map product is available to all government agencies, industry and the public for reference. Major mineral coal and petroleum operations, resources and infrastructure.

The Heavy Mineral Map of Australia Project -- Data Release 1: The Darling-Curnamona-Delamerian Region
공공데이터포털
The National Geochemical Survey of Australia (NGSA) is Australia’s only internally consistent, continental-scale geochemical atlas and dataset. The present dataset contains additional mineralogical data obtained on NGSA samples selected from the Darling-Curnamona-Delamerian (DCD) region of southeastern Australia for the first partial data release of the Heavy Mineral Map of Australia (HMMA) project. The HMMA, a collaborative project between Geoscience Australia and Curtin University underpinned by a pilot project establishing its feasibility, is part of the Australian Government-funded Exploring for the Future (EFTF) program. The selected 223 NGSA sediment samples fall within the DCD polygon plus an approximately one-degree buffer. The samples were taken on average from 60 to 80 cm depth in floodplain landforms, dried and sieved to a 75-430 µm grainsize fraction, and the contained heavy minerals (HMs; i.e., those with a specific gravity >2.9 g/cm3) were separated by dense fluids and mounted on cylindrical epoxy mounts. After polishing and carbon-coating, the mounts were subjected to automated mineralogical analysis on a TESCAN® Integrated Mineral Analyzer (TIMA). Using scanning electron microscopy and backscatter electron imaging integrated with energy dispersive X-ray analysis, the TIMA identified over 140 different HMs in the DCD area. The dataset, consisting of over 29 million individual mineral grains identified, was quality controlled and validated by an expert team. The data released here can be visualised, explored and downloaded using an online, bespoke mineral network analysis tool (MNA) built on a cloud-based platform. Accompanying this report are a data file of TIMA results and a mineralogy vocabulary file. When completed in 2023, it is hoped the HMMA project will positively impact mineral exploration and prospectivity modelling around Australia, as well as have other applications in earth and environmental sciences.
