Offer and submission of drill cores

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

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

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.

Samples that are selected for the drill core library must be delivered 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.
