One of the last areas in the Northern Territory to be upgraded to a modern standard of gravity coverage has now been completed. The Pine Creek region was previously covered by regional scale ground gravity data at 11km spacing as part of the Australia wide gravity data program acquired by the Bureau of Mineral Resources in 1967. The NTGS Pine Creek Ground Gravity Survey commenced during field season 2024 and is now complete, covering more than 40,000 square kilometres, spanning from the northwest coastline to Kakadu National Park in the east and southwards to Katherine. Resolution is improved from historic 11km spacing to station spacing ranging from 500m to 4km.
Funded through the Northern Territory Government’s Resourcing the Territory program, the Survey aligns with the key objectives to drive exploration success through improved geophysical data and to accelerate resource development in established mineral regions. The Survey received significant industry support, with more than one-third of the gravity readings financed by private sector contributions. Geoscience Australia is managing the contract in partnership with NTGS.
The final data is now available for download via GEMIS.
Ground gravity acquisition will now continue westward as part of the NTGS West Arnhem Ground Gravity Survey.
