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.

Tailings Dump Licences mainly licences from 1860 to 1930 Being digitized to help in identifying land where native title claims may be rejected.

Expired Mining and Extractive Licences

Exploration Licences that are no longer Active that expired since 1965. This layer is an amalgamation of ELHST and HISTVIC

Exploration Graticules are used as the main boundaries for Exploration Licences since 1973 - GDA94 - Effective 1st July 2005

Exploration Graticules are used as the main boundaries for Exploration Licences since 1973 - AGD66 - Expires 30th June 2005

Mine Shaft Locations were collected by a variety of methods from 1869 in some areas of the state. Mainly concentrating in Ballarat and Bendigo. In places a shaft may be recorded multiple times with a different source. In cases where several shaft locations are shown close together (generally with separations less than stated position errors) and they have different sources, it is possible that one shaft has been mapped several times. In cases where several shaft locations are shown close together but they have the same information source, it is possible that each shaft location represents a different shaft on the ground. <a href=&#09;http://geology.data.vic.gov.au/searchAssistant/reference.html?q=reference_id:107279&#09;>Bendigo Mines Hazard Data - a Review and History</a> The above created a dataset of around 19000 records More recently, information has been compiled from data from David Bannear - 2017 DELWP - 2017 Parks Vic - 2017 Peter Ward - 2019 - Public Contributor for the Victorian High Country Fred Sargent - 2019 to 2022 - Public Contributor for the Victorian High Country (many thousands added) Peter Quinn - 2019 to 2022 - Public contributor Source for these is marked as Private survey - and source comment contains details. Data is largely shafts. Sometimes quarries, open stopes, adits or workings. Another useful dataset is MINSITE aka Vicmine aka Mines and Mineral Occurrences (more for resource, production, reference links and mineplans)

The areas occur usually when part of an Exploration Licence is relinquished. It means that no-one can apply over the vacant ground for usually 3 months from when the moratorium began. Refer to the Mineral Resources (Sustainable Development) Act (MRSDA) for more detail.

Regions showing the extent of Exploration Licences & Moratorium Periods currently lodged with Earth Resources Regulations. The boundaries are derived from a combination of entering graticular boundaries (exact MGA or 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) for more detail.

Contains details only on current titles. The idea is to save the original area and when the title finally expires, transfer it to the expired layers eg ELHST
