DIGS is a public, online archive that provides access to non-confidential reports and other important documentary material held by the Resources & Energy Division.  A new version was released in October 2016, with new spatial searching and filtering capabilities.

What information is held within DIGS?

DIGS includes a wealth of exploration, geological and mining information in the form of departmental reports, publications, maps, plans and heritage records as well as reports, data and mine plans produced by exploration and mining companies that have been submitted to the department to comply with the NSW mining-related regulations.

There are over 140 000 reports, with approximately 3.5 million pages - that’s 2 terabytes of digital data dating back to 1875.

Details of the DIGS collections

The records are presented as two collections: reports and publications.  These are based on the source databases; the original DIGS archive and the Geoscience Product Catalogue respectively. As a result, they have different metadata which can be used to sort or filter.

Report collection includes:

  • Exploration and mining company reports
  • Company environmental reports
  • Title licence conditions
  • Mine records
  • Mine plans, record tracings and survey diagrams
  • Technical and research reports
  • Cartographic plans
  • Heritage maps

Publication collection includes:

  • Maps
  • Explanatory Notes
  • GIS data packages
  • Geophysical survey images
  • Bulletins
  • Quarterly Notes
  • Coal and Mineral Industry Profiles
  • Books
  • Mine Records
  • Field excursion guides
  • Fact sheets
  • Scientific posters
  • Presentations
  • Promotional materials

Access to reports and publications

Confidential reports: Company reports for mineral exploration remain confidential whilst the title is active. Generally reports are made open file (non-confidential) when the title expires and there is no flow-on licence.  Approximately 88% of documents are classified open file and therefore can be read or downloaded from the DIGS system.

Free download: Publications that have no cost and are available in a digital format can be downloaded directly from DIGS at no charge.

Purchase online: Items with an associated cost can be ordered using a credit card at the Online shop or directly from the department using an order form or by phoning.
