Description: Program sites are classified by risk category and status as priority (high and extreme risk), surveillance (low and medium risk), and re-commercialised (where a site has subsequently become actively mined or re-purposed to an alternative productive use).
Description: A Vent pipe is installed either; above ground as a vertical pipe or, as a grated vent at surface to allow for the release of air to mitigate the upward pressure impact of rising water table on the cap and/or dangerous gases that can build up over time. Vents can sometimes be offset (e.g.. fence) to reduce the visual and physical impacts to property.
Description: A shaft is primary vertical or non-vertical opening through mine strata used for ventilation or drainage and/ or for hoisting of personnel or materials; connects the surface with underground workings.An adit is an opening driven horizontally into the side of a mountain or hill for providing access to a mineral deposit or for drainage;A decline is a sloping underground opening for machine access from level to level or from surface; also called a ramp.An incline shaft is a principal entrance to a mine sloping at about 45 degrees to follow the dip of an ore body.

Description: One of the main forms of remediation of an abandoned, mine opening (making the opening safe) is the construction of a reinforced, concrete cap at competent rock or, basement material and subsequently, backfilled to original surface. A cadastral connection survey is performed after the cap installation and the excavation is still open. A Mines Plan of the survey is lodged and registered against the property. These can be searched and obtained through the Titles Registry or approved distributors.
Description: Surface mine pits relating to abandoned mines and include benched and un-benched open cuts, strip mining and alluvial mining related pits.

Description: Tailings is residual material that has been crushed and ground and/or washed and rejected from a mill or processing plant after the ore minerals have been extracted. Tailings can be found in engineered constructed tailings storage facilities, contained or uncontained historical tailings, and contained or uncontained slimes from alluvial mining.
Description: These areas contain multiple shafts and other surface working related to underground mining.This includes shafts, adits, declines and inclines used to extract mineral ore have been located and recorded.
Description: Mapping extent derived from historic, underground mine working plans and georeferenced from the local mine grid system to a real-word, reference system. These can be either hardcopy (historic) or more recently, digital file.
