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.

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.
