NSW minerals, coal and petroleum
New South Wales has abundant mineral and coal resources, including world-class deposits of gold, copper, lead, silver, zinc and mineral sands.
Maps and other products
Hard copy geological maps are available at several scales.
There is almost complete coverage of the state at 1:250 000 and there are several statewide maps.
Most of the mineral deposit maps are 1:250 000 metallogenic maps.
Other maps are the 1:50 000 metallogenic maps of the Broken Hill and New England areas, and the 1:500 000 metallogenic map of Sydney.
Statewide and regional geophysical maps resulting from airborne surveys can be purchased.
Heritage maps and documents
Over 500 heritage geological maps have been catalogued, conserved, scanned and archived.
There is also a unique collection of over 800 geologically notated parish maps.
Memoirs, images, mine records and plans, even newspaper cuttings going back to 1851, are among the many documents archived in the DIGS® database.
They can be accessed and downloaded online.
An authoritative range of publications can help you learn more about mining and minerals in NSW, including books, newsletters, fact sheets, brochures and scientific papers.

Mineral Resources geoscience activities
The Mineral Resources unit of NSW Department of Industry, Resources & Energy supports the profitable and sustainable development of mineral resources.
Our geoscientists use state-of-the-art methods and systems to collect, synthesise and store accurate information about the geology, mineral, coal and petroleum resources of NSW.
This information is then shared with the exploration and mining industries, government and the community.
Geoscience activities in Mineral Resources are managed by:
Some of the main functions of Mineral Resources geoscience are:
- Geological mapping
- Geophysical surveys
- Mineral systems studies
- Sedimentary basin studies
- Online services
- Mineral, coal and petroleum exploration and mining assessment
- Land use assessment
- Drill core library management
- Database management
