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.

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.

Mineralisation Zones are areas of the state that represent Brown Field areas where only 70 Block exploration licence applications are permitted. Outside of these areas (Green Field) 200 block exploration licence applications are permitted. Mining Act 1978 Section 57 - Grant of Exploration Licence (1) Subject to this Act the Minister may on the application of any person and after receiving a recommendation of the mining registrar or the warden in accordance with section 59, grant to that person a licence to be known as an exploration licence on such terms and conditions as the Minister may determine. (2) The area of land in respect of which an exploration licence may be granted shall be a block or blocks but shall not be more than 70 blocks unless subsection (2aa) applies. (2aa) If the area of land referred to in subsection (2) is in an area of the State designated under section 57A(1) it shall not be more than 200 blocks. Section 57A (5) If — (a) an application for an exploration licence is made in respect of an area of land that is in an area of the State designated under subsection (1) (a designated area); and (b) before the application is determined the designation is varied or cancelled under subsection (2) with the result that the area of land to which the application relates ceases to be in a designated area, then, despite that variation or cancellation, section 57(2aa) applies as if the area of land were in a designated area.
