Areas unavailable for mineral exploration or mining across Tasmania. Polygons delineate areas in which exploration licence and mining lease holders are not permitted to explore for or extract minerals or atomic substances. Areas include those areas defined as unavailable under the Mineral Resources Development Act 1995 and areas which have been administratively excluded by Mineral Resources Tasmania.

Mining Lease polygons and production licence polygons for all mineral categories across Tasmania, with tenement information derived from the TIGER system; administered by Mineral Resources Tasmania (MRT), Department of State Growth. Mining Lease polygons delineate areas in which lease holders are permitted to conduct mining operations. Mining Leases may be granted over both Crown and private land, so long as that land falls under the Mineral Resources Development Act 1995. Mining operations include: obtaining and treating minerals, storing and containing minerals or waste material generated on a lease or another area, and activities associated with mining. Mining also includes production activities in relation to a category 4 mineral or a category 6 mineral.

The Mining (Strategic Prospectivity Zones) Act 1993 recognises the high mineral prospectivity of many areas of Tasmania. Within the Strategic Prospectivity Zones (SPZ) there are restrictions on changes of the status of parcels of Crown Land. The status of Crown land parcels <500 ha in size can only be changed with the agreement of the Director of Mines; those of > 500 ha in size cannot be changed without the approval of both houses of parliament. Should a change in land status made by the State have the effect of revoking a mining lease or an exploration licence, the tenement holder is entitled to compensation. The State is, however, not responsible for actions of the Australian Government which may preclude exploration or mining. activity, such as the nomination of parcels of land for World Heritage status. Changes in status of land can also be made in extreme circumstances, for example if a species of flora or fauna was to become rare, vulnerable or endangered as a result of mining activity, or where an area having cultural or natural heritage value could suffer substantial effects as a result of mining operations. In these cases the Crown may, after a recommendation from the Resource Planning and Development Commission and some Ministers, change the status of that piece of land, and compensation is payable for this action.

Current Exploration Licence polygons (including applications and exploration release areas) across Tasmania, with tenement information derived from the Tasmanian Information on Geoscience and Exploration Resources (TIGER) system; administered by Mineral Resources Tasmania (MRT), Department of State Growth. Exploration licence polygons delineate areas in which licence holders are permitted to explore for the listed categories of minerals: Category 1: metallic minerals and atomic substances; Category 2: coal, peat, lignite, oil shale and coal seam gas; Category 3: rock, stone, gravel, sand and clay used in construction, bricks and ceramics; Category 4: petroleum products except oil shale; Category 5: industrial minerals, precious stones, semi-precious stones; Category 6: any geothermal substance. Exploration licences may be granted over both Crown and private land, so long as that land falls under the Mineral Resources Development Act 1995. Mineral exploration activities may include: geological, geophysical and geochemical surveys, drilling, and taking samples of rock, soil, water or other substances for analysis. Mining is not an exploration activity and cannot occur on an exploration licence.

The state of Western Australia is divided into various mineral fields, some are further divided into districts under powers contained in Section 16 of the Mining Act 1978. This dataset was formally known as Mineral Field Boundaries (DMP-004)

Declared fossicking areas as defined under section 116 of the Mineral Resources Development Act 1995

Non-current mining Lease polygons and production licence polygons for all mineral categories across Tasmania, with tenement information derived from the TIGER system; administered by Mineral Resources Tasmania (MRT), Department of State Growth. Non-current records include leases that were registered but never granted (application withdraw, lapsed or refused) as well as leases that were granted and later ceased to be current (e.g. expired, surrendered, renewal refused, revoked etc.). In cases where a partial surrender was approved during the term of the lease, only the final area is represented in this dataset. Mining Lease polygons delineate areas in which lease holders are permitted to conduct mining operations. Mining Leases may be granted over both Crown and private land, so long as that land falls under the Mineral Resources Development Act 1995. Mining operations include: obtaining and treating minerals, storing and containing minerals or waste material generated on a lease or another area, and activities associated with mining. Mining also includes production activities in relation to a category 4 mineral or a category 6 mineral.

The geology of Macquarie Island was mapped December 1994 - January 1996 in a joint project involving Mineral Resources Tasmania, the Australian Antarctic Foundation and the Australian Antarctic Division.

Mineral occurrences, including operating and abandoned mines, located in Tasmania, with summary mineral occurrence data, derived from the Mineral Occurrence Database, which is a component of the Tasmanian Information on Geoscience and Exploration Resources (TIGER) system; administered by Mineral Resources Tasmania (MRT). Mineral occurrences include operating and abandoned mines, prospects, mapped occurrences and mineral fields or mineralised areas. Mineral occurrences are shown subdivided by commodity type, which largely corresponds to the mineral categories defined in the Mineral Resources Development Act 1995; Fuel Minerals, including geothermal (Categories 2, 4 and 6), Construction Minerals (Category 3), Industrial minerals (Category 5) and metallic minerals (Category 1). Alluvial, placer and man-made (tailings dam) occurrences are shown separately (commodities are mineral Categories 1 and 5) and occurrences (generally abandoned mine workings) where there are no records of the commodity of interest, are shown as unknown. The summary Mineral Occurrence data includes: the Mineral occurrence name (note that an occurrence may have multiple names or aliases), the commodity type (as defined above), the nature of the occurrence (e.g., mine or prospect, mineralised area), the commodity or commodities present, the geological unit that hosts the occurrence and the positional accuracy of the record. A Details field provides a link to a Mineral Occurrence Details page where further information, including references and public domain resource figures, may be available.

Catalogue of published geoscience maps produced by Mineral Resources Tasmania. Map themes include geology, engineering geology, land stability and geohazards, mineral deposits, groundwater resources, and geophysics. Maps have been produced at various scales ranging from statewide maps to more detailed regional mapping. The map catalogue can be searched and map images downloaded on the MRT website https://www.mrt.tas.gov.au/products/database_searches/map_catalogue or more popular maps and map series are listed in the MRT Publication List https://www.mrt.tas.gov.au/__data/assets/pdf_file/0005/229640/Price_list_v2.2.pdf
