Non-current mining Lease polygons and production licence polygons for all mineral categories across Tasmania, with tenement information derived from the TIGER system; administered by Mineral Resources Tasmania (MRT), Department of State Growth.
Non-current records include leases that were registered but never granted (application withdraw, lapsed or refused) as well as leases that were granted and later ceased to be current (e.g. expired, surrendered, renewal refused, revoked etc.). In cases where a partial surrender was approved during the term of the lease, only the final area is represented in this dataset.
Mining Lease polygons delineate areas in which lease holders are permitted to conduct mining operations. Mining Leases may be granted over both Crown and private land, so long as that land falls under the Mineral Resources Development Act 1995. Mining operations include: obtaining and treating minerals, storing and containing minerals or waste material generated on a lease or another area, and activities associated with mining. Mining also includes production activities in relation to a category 4 mineral or a category 6 mineral.
