This amalgamated layer is made up of several layers. These are: Tailings Licences - Expired (tlhst), Gold Mining Licences - Expired (gmlhst), Mineral Leases - Expired (milhst), Expired Extractive Industry Work Authorities (ewahst), Expired Mining Licences (minhst), Exploration Licences - Not Active (1973+) (elhist), Exploration Licence Moratorium Period Areas (mp), Proposed Work Authorities (wap), Mining Licences (min), Extractive Industry Work Authorities (ewa), Exploration Licences (el). The boundaries are derived from a combination of entering graticular boundaries (exact AMG co-ordinates) and digitizing along areas of land status (Minerals and Petroleum version of landmmt100) which are unable to be mined or explored. Refer to the Mineral Resources Development Act (MRDA) for more detail.

Non-current Exploration Licence polygons 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. Non-current licences includes licences which were registered but never granted (e.g. application was withdrawn, lapsed or refused) as well as licences that were granted and later ceased to be current (expired, surrendered, renewal refused etc.). In cases where a partial surrender was approved during the term of the exploration licence, only the final area is represented in this dataset. Exploration licence polygons delineate areas in which licence holders are permitted to explore for the listed categories of minerals. 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.

Resource authorities partially surrendered in Queensland during the last year. Reports are published where data is available for the relevant period. If a change or approval has not occurred during a period, there will be no report available.

Section 19 – Under Section 19 of the Mining Act (1978) the Minister, or his delegate, may exempt any land, (not being private land or land that is the subject of a mining tenement or of an application therefore), from mining or any specified provisions of the Mining Act. The distinguishing factor is that a S19 can only exist by Ministerial approval and Gazettal and although a S19 can be created over any land it can never co-exist with private land or mining tenure. The primary purpose of a S19 is to provide a 24-month period for the interested party to organise the reserving or leasing of the area but a S19 can also be created for other reasons subject to the Minister or his delegate being satisfied it is warranted. There is provision that the Minister, or his delegate, may vary, cancel and extend the term of a S19 for a period or periods (not exceeding 2 years at a time) and this is commonly done. Any creation, variation or cancellation of a S19 must be published in the Government Gazette. The S19 will expire if is not extended. Prior to 14 October 1995 S19s were created with an indefinite term and can only be removed by having the Minister cancel the S19.

Resource authorities renewed in Queensland. Reports are published where data is available for the relevant period. If a change or approval has not occurred during a period, no report will be available.

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.
