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.

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.

Regions showing the extent of Prospecting Licences currently lodged with Earth Resources Regulations. The boundaries are derived from a combination of entering graticular boundaries (exact MGA co-ordinates) and digitizing along areas of land status (Earth Resources version of plm25) which are unable to be mined or explored. Refer to the Mineral Resources (Sustainable Development) Act (MRSDA) 1990 for more detail.

Regions showing the extent of Mining Licences currently lodged with Earth Resources Regulations. The boundaries are derived from a combination of entering graticular boundaries (exact AMG co-ordinates) and digitizing along areas of land status (Earth Resources version of landmmt100) which are unable to be mined or explored. Refer to the Mineral Resources (Sustainable Development) Act (MRSDA) 1990 for more detail. (MIN is included in ML) NOTE: For GeoVic, "Operating Gold Mines" are a subset of this dataset where during the current financial year the tenement recorded production in excess of 100 kg Au, and/or are currently at an advanced stage of resource development with a target production rate of at least 100kg Au per year.

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.

A composite map layer that displays the land tenure of Tasmania classified as to whether or not prospecting is allow, this is overlaid and over-ridden by a subset of the areas unavailable under the Mineral Resources Development Act 1995. The layer also shows all current mineral tenements, and declared fossicking areas.
