Core library services and drill core submission

The Geological Survey of Queensland has a large collection of cores and cuttings from Queensland's known mineral deposits and coal and petroleum basin strata.

These have been contributed by in-house field programs as well as by private companies as part of their compliance with Queensland's exploration legislation.

Submitting core and cutting samples

We collect core submitted by exploration companies as part of legislative requirements.

Read the core and cuttings submission guidelines (PDF, 557KB) for more detail on submitting material to the core collection.

Contact the Exploration Data Centre if you are unsure about your submission obligations or for more information about how to submit core.

Pre-lodgement notification

Before lodging your sample, send us a drill hole metadata form (PDF, 547KB) with details of the drill hole material you are planning to submit. Refer to the drill holes samples data dictionary (PDF, 530KB) for a description of terms.

Send your form to either the Exploration Data Centre or the John Campbell Miles Drill Core Facility.

We will assess your samples to determine whether they duplicate existing material and let you know which samples you should lodge.

Packaging and delivery of samples

Once you have been notified of what you need to supply:

  1. Package the required samples and read the sample trays, pallets and delivery guidelines (PDF, 1.3MB) for detailed instructions.
  2. Make sure you include a drill hole sample submission form (PDF, 279KB) with each shipment.
  3. Send your shipment to the nominated core library.

Inspecting and sampling core and cuttings

You can inspect any open file sample held by the Geological Survey of Queensland. You can also obtain samples for further analysis, subject to terms and conditions.

For a listing of bore holes held by us, you can search in GeoResGlobe or in QSpatial.

To request an inspection, contact the manager at the Exploration Data Centre or the John Campbell Miles Drill Core Storage Facility. You will need to make a written request to obtain samples.

Site facilities

We have sampling and slabbing facilities, or you can request that our staff do this for you.

We supply acid, sample bags, tags and geology picks or hammers.

Read the Exploration Data Centre brochure (PDF, 2.0MB) and the John Campbell Miles Drill Core Storage Facility guide (PDF, 297KB) for more details.

Note: You must wear covered footwear at all times in our facilities.

HyLogger data

HyLogging is an advanced technique from CSIRO that helps geologists to non-destructively assess the mineralogical distribution of an entire drill core, with minimal sample preparation or removing from its original tray.

The data produced by the Queensland Government’s HyLogger contributes to the AuScope National Virtual Core Library (NVCL) project.

This project in turn contributes to the AuScope National GeoTransects Program, which is progressively building a high-resolution image of the geology of the upper 1-2 km of the Australian continent.

You can access Queensland’s HyLogger data through the Geoscience Portal.

  • Under the Add Data menu in the layers panel, expand the Boreholes heading, and click on National Virtual Core Library.
  • Use the drop-down to select Provider = Queensland, then click Add data to Map.

Note: Because of its commitments under the national program, the Geological Survey of Queensland is no longer able to offer commercial HyLogging services to industry.
