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.

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).
