Core library services and drillcore

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.

We are also interested in collecting any core that companies want to make available.

Read the core and cuttings submission guidelines 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 with details of the drill hole material you are planning to submit. Refer to the drill holes samples data dictionary 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. Read the sample trays, pallets and delivery guidelines for detailed instructions.
  2. Make sure you include a drill hole sample submission form 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.

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 and the John Campbell Miles Drill Core Storage Facility guide for more details.

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