Offer and submit drill cores

Before ceasing activities on the mineral title, as the titleholder, you must request approval to dispose of drill cores, cuttings or other geological samples collected from the following title areas:

  • exploration licences (EL)
  • exploration retention licences (ERL)
  • extractive mineral leases (EML).

This is a requirement under the Mineral Titles Act 2010.

As soon as you are finished analysing drill cores or cuttings, and before ceasing activities on the mineral title, you should offer them to the Northern Territory Geological Survey (NTGS).

Each drill core offer is evaluated for inclusion in the core library collection.

You must deliver samples that are selected for the drill core library to the NTGS Core Facility in Alice Springs or Darwin.

Samples not selected for the core library collection may be disposed of after you have received written authorisation from NTGS.
