The NTGS Pine Creek Ground Gravity Survey is currently underway and will acquire almost 13,000 ground gravity readings at station spacing of 4 km to 500 m across the northwest of the Northern Territory. The survey covers an area of over 40 000 square km stretching from the northwest coastline across to Kakadu National Park in the east and extending as far south as Katherine. The survey was funded through the Northern Territory Government's Resourcing the Territory program with industry contributions funding acquisition of over one third of the total readings acquired. Contract management for the survey is being undertaken by Geoscience Australia in collaboration with NTGS.
This dataset improves the resolution and quality of the previous 11km spaced Bureau of Mineral Resources regional-scale ground gravity acquired in 1967 and meets Resourcing the Territory's key objectives of underpinning exploration success through enhanced geophysics and accelerating resource development in known mineral provinces.
Data will be updated progressively with the most recent data released on 20/10/2024.
The preliminary data is now available for download from NTGS' FTP site.
