Industry data capture

Dedicated programs to upgrade the Northern Territory geoscience databases and online delivery systems.

A major program is underway by the Northern Territory Geological Survey (NTGS) to capture all remaining legacy open-file exploration drilling and geochemistry data across the Northern Territory (NT), commencing with the McArthur Basin, Tennant Creek and Barkly regions.

In October 2016 a project to collect all the drilling and geochemistry from all currently held exploration leases in the NT was initiated.

This project is largely complete and has led to the release of:

  • More than 298,000 geolocated samples, and
  • Over 18,500 new drillhole collars.

Digital back-capture of legacy drilling and geochemistry commenced with a data capture project covering the prospective Batten Fault Zone area in the McArthur Basin in 2018 and early 2019. In 2019‑20, legacy data capture was undertaken in the Tennant Creek mineral field and then extended over the remainder of the Barkly region.

Since Resourcing the Territory commenced, data has been digitally captured from 1,457 company reports. This data includes the location of 70,334 drillhole collars, with 344,414 geochemical assays from these drillholes.  A further 142,215 surface geochemical assays (including stream, soil and rock-chip geochemical analyses) have been captured and spatially geolocated.

This newly captured data will provide explorers in the Tennant Creek and Barkly region with immediate access to a complete and spatially located dataset of all historic drilling and geochemistry in the area. This is an important pre-competitive dataset to allow industry to rapidly assess and interpret past exploration in the area.

This new data is being progressively released as part of the Territory-wide Drilling and Geochemistry GIS datasets are available through STRIKE, the NTGS Digital Information Package DIP001 or via the NT-wide geoscience datasets webpage.
