Accessing the drill core library
The Northern Territory Geological Survey (NTGS) has core libraries in Darwin and Alice Springs.
The libraries hold drill core and cuttings collected during government and industry mineral and petroleum industry exploration drilling.
You can search drill core and cuttings which are catalogued in the drill core database COREDAT.
Viewing or sampling drill core and cuttings
Drill core and cuttings can be viewed and sampled by researchers in industry, government and research organisations.
You will need to make an appointment and obtain approval for any sampling prior to your visit.
To view or sample cores or cuttings, download and submit the request form.
Visit or contact the core library
When visiting the core library you must wear steel-capped boots.
For core library addresses and contact details go to Mines and Energy contacts.
The core libraries are open Monday to Friday 8.00am to 4.15pm.
As sampling usually results in destruction of the sample, you must provide raw data and details of analytical methods used in the sampling six months after sampling. The data is then made available to the public twelve months after sampling.
Sampling of core and cuttings will only be permitted if no similar analysis has been recently completed and there is sufficient sample available for the particular sample interval requested.
Read the core sampling policy.
Core sample reports
You can search reports and data from studies on core and cuttings held in the NTGS core libraries in the Core Sample Reports catalogue.
Water bore cuttings
Cuttings from water bores are also stored at the NTGS core libraries.
