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.

Geological lines (contacts, faults, linears), geological rock units, and structure data derived from 1:50,000 and 1:63,360 Digital Geological Atlas printed map series and 1:25,000 digital geology data where available. Geological units and boundaries have been generalised and compiled for 1:250,000 scale. The digital data is available as a seamless state wide coverage and is used to produce the Digital Geological Atlas 1:250,000 Scale map series.

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.

Stratotectonic map of Tasmania at 1:500,000 scale indicating main elements of Tasmanian geology, including categories of boundaries to elements, and depth to granite batholiths. Accompanied by large-format Time-Space Diagram of Tasmania and report (Seymour, D.B., Calver, C.R., 1995; Explanatory notes for the Time-Space Diagram and Stratotectonic Elements Map of Tasmania. Tasmanian Geological Survey Record 1995/01).

Simplified geology data derived from 1:250,000 digital geology. Structural symbols and boundaries have been removed and lithological subdivisions of the main rock units have been consolidated, whilst preserving the time scale framework of the State's geology. Intended as an input to regional planning processes.

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.

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.

Geological lines (contacts, faults) and geological rock units, derived from 1:250,000 geology data. Rock units have been simplified based on a parent 1:500,000 unit, geological boundaries have been generalised to be suitable for 1:500,000 scale data. The digital data is available as a seamless state wide coverage and is used to produce the Geology of Tasmania 1:500,000 Scale map.

Geological lines (contacts, faults, linears), geological polygons (rock units and alteration or metamorphism) and geological points (outcrops and structure data) derived from existing reports, 1:25,000 1:50,000 and 1:63,360 scale printed maps, new field mapping and interpretation of aerial photography, remote sensing data and airborne geophysical data. Digital data is available as a seamless layer, with the understanding that it may include unresolved edge-matching issues originating from mapping project boundaries in the source data. The digital data is used to produce the Digital Geological Atlas 1:25,000 Scale map series.

The Tasmanian report database provides an index to over 10,000 reports held in hardcopy form by MRT. The reports date from 1878 to the present and form a comprehensive summary of exploration philosophy and activity. This database details many attributes of Department and Company reports and is available for free searching online (http://www.mrt.tas.gov.au). The reports include those issued by the Department of Mines and Mineral Resources Tasmania, and have been issued under various series including Geological Survey Bulletins, Underground Water Supply Papers, Mineral Resource surveys and Geological Survey Records, also printed reports by mining exploration companies on their mineral exploration activities in Tasmania and including seismic surveys and well completion reports relating to petroleum exploration in Tasmanian waters. Items include: title, author, company, tenement, location, key words (minerals, deposits, exploration methods) and a brief abstract.
