Abstract
This map portrays deposits of a range of commodity types. These include metallic, industrial, coal and selected construction material sites with a known commodity endowment (past production and global resources). Sites with a known commodity endowment of less than A$10 000 are shown as a point only. There has been no attempt to reflect the potential of an area. The Bathurst 1:250,000 metallogenic map displays:
- metallic mineral deposits show as a symbol indicating the mineral system type, the relative A$ value and a reference number;
- industrial mineral deposits shown by a symbol indicating the mineral system type (where applicable), the relative A$ value and a reference number;
- selected construction material sites with commodity type, relative A$ value and a reference number;
- the location of aerially extensive gold placers - many of which were mined during the mid to late 19th century;
- the aerial extent of geological units containing significant, generally un-quantified, limestone resources.
The reference number given to each symbol relates to the table below the map. This table gives the deposit name (where known) and its major-(minor) commodities.
Hard rock metallic and industrial mineral deposits shown on the Bathurst 1:250,000 map generally relate to the Ordovician to Carboniferous Lachlan Orogen (see Geological History on the reverse side of the map). As a consequence, younger cover units, including those relating to the Permo-Triassic Sydney Basin, the latest Eocene to late Miocene volcanic units and unconsolidated sedimentary rocks of mainly Quaternary age, are shown as semi-transparent overlay of basement units.

Comments
This is a double sided map where side two of the map contains Mining and Geological History of the Bathurst Region. Not all of the deposits on the map are listed in the 1972 Mine Data sheets.
