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.

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 and Gulf regions including the southern McArthur Basin, South Nicholson Basin, Lawn Hill Platform, Murphy Province, Warramunga Province and the northern Georgina Basin

In the first three years of Resourcing the Territory, data has been digitally captured from 2,967 company reports. This data includes the location of 116,436 drillhole collars, with 529,429 geochemical assays from these drillholes.  A further 234,205 surface geochemical assays (including stream, soil and rock-chip geochemical analyses) have been captured and spatially geolocated. This newly captured data is providing explorers in the Tennant Creek, Barkly and Gulf regions 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. With data capture across this region nearly complete, the program will rolled out more broadly across the Territory

This new data is being progressively released as part of the Territory-wide Drilling and Geochemistry GIS datasets are available for download in MapInfo tab, KML, ESRI shapefile and csv file formats through STRIKE, the NTGS Digital Information Package DIP001 or via the NT-wide geoscience datasets webpage.
