The data contains sub-surface geological rock units. Multiple datasets may exist over some tiles, numbered as SGEOLn. The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by other datasets representing geology outcrop and boundaries, structural lines, miscellaneous lines and points, miscellaneous polygons, metamorphism, and placer deposits.

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.
