Provide deep-crustal seismic data over the Macquarie Arc, imaging Earth's crust down to about 40-60km, using specialised equipment along existing roads and tracks.
NSW Resources is supporting NSW energy transition through the critical mineral and high-tech metals strategy by:
A seismic survey in Central NSW will help to image deep structures in Earth’s crust, like an ultrasound. This image will improve our understanding of the structures and geology of the Hermidale Terrane, Hill End Trough and Macquarie Arc in the Central Lachlan Orogen. These areas are prospective for critical and high-tech metals needed for NSW energy transition, and for deep groundwater sources in sandstones (the Great Artesian Basin).
The project follows on from seismic acquisition in 2025. Seismic acquisition needs to start by March 2026. Acquisition must be complete by early June.
Seismic data will inform us about:
All data acquired will be made publicly available (as pre-competitively data). Seismic data is used by explorers, engineers and geoscientist to better understand rocks.
Approximately 400 km Hybrid shallow and deep-crustal reflection seismic data over Central NSW with traffic control and possibly a ground gravity survey, if the budget permits. For technical details, please see Part D - Statement of Requirements.
