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.

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.

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.

The Land Tenure data set contains a representation of the commonly accepted land tenure classifications for Tasmania. Tenure Classifications include Crown Land, Private Land, Local Government and other Statutory Authority Land, Reserved Land, Conservation Covenants, Private Reserves, Permanent Timber Production Zone Land (formerly State Forest). Future Potential Production Forest (FPPF) land is also distinguished where it overlaps Crown and HEC land. This dataset depicts the full extent of classifications and as some or coastal reserve boundaries extend to Low Water Mark, and in some cases include areas of estuary or sea. These classifications generally conform to those represented on the TASMAP Land Tenure Map.

Prior to the introduction of GIS mapping and the Tasmanian Information on Geoscience and Exploration Resources (TIGER) system, all mineral tenements - leases and licences - where mapped on paper. In addition to the individual tenement map, the outline was also charted on a mineral tenement chart, and in some cases a reference to tenement map or survey number was included. As the charts filled up, they would be retired and a new version started with all tenements current at the time transferred across to the new chart. These charts have now all been scanned and a digital index created of the map extents.
