b'Geophysics in the surveysNewsGeological Survey of Queensland: Current GSQ geophysics programmes and future workIt has been a busy year for the geophysics group at the Geological Survey of Queensland. We have been rolling out data and reports from the New Economy Minerals Initiative (NEMI) geophysics programmes. In July, the Queensland Government announced an additional $37.5 million in support of critical minerals exploration in Queensland as part of the Queensland Resources Industry Development Plan. This funding package includes an expansion and continuation of the Collaborative Exploration Initiative and $10 million for an expanded geophysical programme over the next few years. Geophysical project planning for these additional funds is well underway with programmes to be progressively announced over the next 12 months. Applications for the next round of the Collaborative Exploration Initiative will be open from 1 December 2022 until 11January 2023.We have been hard at work on interpretation and modelling projects to value add to existing datasets. Following the release of the 2021 Kamilaroi airborne magnetic and radiometric survey a new merged set of magnetic and radiometric grids was generated in the Mount Isa region. This new dataset, the Mount Isa Region Airborne Data Merge 2022 was produced from the five recently flown high-resolution GSQ geophysical airborne magnetic and radiometric survey and data from seventeen surrounding open-file exploration surveys. The final set of merged grids covers an area of approximately 44 000 km2 of the highly prospective North West Mineral Province with a cell size of 10 m (Figure 1).A large-scale reinterpretation of existing deep crustal seismic has been an ongoing focus for the Regional Compilations team in the GSQ.
