The Queensland Government is now in caretaker mode until after the state election. Minimal updates will be made to this site until after the election results are declared.

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.

Legislative obligation to submit core and cuttings samples

We collect core, cuttings and other samples submitted by exploration companies as part of legislative requirements.

How to submit core and cuttings samples

As there is limited storage capacity at the Exploration Data Centre Core Library in Brisbane and John Campbell Miles store at Mount Isa, new drill hole samples are being vetted against existing samples to determine if they offer a new or more representative stratigraphic section for the region.

Provide details of proposed drill hole material prior to lodgement. We will assess your samples and notify you which samples are required to be submitted.

Notification and offer of core and cuttings samples: Petroleum and coal seam gas

This section relates to offers of core and cuttings by petroleum tenure holders under the Petroleum and Gas (Production and Safety) Act 2004.

Before lodging your sample, email us at geological_info@dnrme.qld.gov.au with the required details of the drill hole material you are planning to submit.

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

For offers of core, please advise:

  • tenure type and number
  • operator name
  • well name and number
  • well location (i.e. grid coordinates and datum)
  • core type (e.g. full hole core)
  • cored interval(s) with top and bottom and recovery specified in metres
  • core diameter as specified in original units of measure
  • core general condition
  • core recovery date (i.e. the date at the which last cored interval in the well was recovered)
  • number of core boxes
  • number of pallets
  • geological information (e.g. the formations and/or other stratigraphic units intercepted and depth in metres, or any evidence of fault intersections or other geological points of interest)
  • note sections of removed core (e.g. core remaining in analysis) if relevant
  • core photography.

For offers of cuttings, please advise:

  • tenure type and number
  • operator name
  • well name and number
  • well location (i.e. grid coordinates and datum)
  • volume of cuttings collected (e.g. frequency of sampling per interval, amounts in weight per sample bag, number of packing boxes)
  • method of storage (e.g. in cloth or plastic sample bags)
  • whether cuttings been washed and air dried.

Packaging and delivery of samples

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

Notification and offer of core and cuttings samples: Minerals and coal

This section relates to offers of core and cuttings by mineral and coal tenure holders under the Mineral Resources Act 1989.

Before lodging your sample, email us at geological_info@dnrme.qld.gov.au with the required details of the drill hole material you are planning to submit.

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

For offers of core, cuttings, bulk samples, etc. please advise:

  • tenure type and number
  • principal holder name
  • bore name and number
  • bore location (i.e. grid coordinates and datum)
  • sample type (e.g. full hole core, cuttings, bulk sample, etc.)
  • relevant interval(s) with top and bottom and recovery specified in metres
    (Note: This component is intended to describe the downhole element of a sample, in addition to the provenance, i.e. sieved fractions.)
  • volume of sample
  • method of storage (e.g. plastic sample bags, drum, cloth, steel core tray, etc.)
  • core diameter as specified in original units of measure
  • sample general condition (e.g. washed, dried, weathered, etc.)
  • core recovery date (i.e. the date at the which last cored interval in the well was recovered)
  • number of core boxes
  • number of pallets
  • geological information (e.g. formations and/or other stratigraphic units intercepted and depth in metres, or any evidence of fault intersections or other geological points of interest)
  • note sections of removed core (e.g. core remaining in analysis) if relevant
  • available sample photography.

Packaging and delivery of samples

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.

Contact the Exploration Data Centre for more information.

For a listing of bore holes held by us, you can search in GeoResGlobe or in QSpatial. Select the Boreholes core, cutting or sidewall held layer to search for specific cores.

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

Site facilities

We have sampling and slabbing facilities on site, and rock cutting is a service our staff can provide to our customers.

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

Read the Exploration Data Centre brochure (PDF, 2MB) 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.

The Hylogger is currently being used full time as part of the GSQ Reference Collection Project. We are no longer offering commercial HyLogging services.

If you are interested in collaborating with GSQ as part of this project by either donating or loaning drill core, please email Geological_Info@dnrme.qld.gov.au.

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.

Contact us

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