b'Geophysics in the SurveysNewsGeological Survey of New South Wales: New products and dataThe Geological Survey of New South Wales (GSNSW) collects, manages and distributes geological, geophysical, geochemical and geospatial data to inform government, resource industries and the community about the states geology, and mineral and energy resources.Important regional projects are supported by the New Frontiers Initiative, which is funded by industry through mineral and petroleum annual rental fees. The initiative aims to improve knowledge of under-explored areas within NSW, which includes acquisition of precompetitive geophysical data that provides essential support for geoscience mapping and mineral exploration.Some GSNSW key achievements from the past year are outlined below.Cobar MinEx CRC airborne EM survey commencing soonGSNSW has committed $16 million over ten years towards the MinEx CRC National Drilling Initiative. Mineral Allocation Areas have been declared in five undercover regions around Cobar, Dubbo, Mundi and Forbes. GSNSW will acquire new data in these areas to learn more about the mineral potential of the underlying bedrock. As part of the first project, a regional-scale airborne electromagnetic (AEM) survey will beFigure 1.Area of the Cobar MinEx CRC AEM survey over first vertical derivative magnetics image.

The survey will be flown along eastwest lines spaced 2.5 km and 5 km apart, and may also incorporate closer spaced infill lines funded by industry. The survey is being managed by Geoscience Australia and will start in September.Contact: astrid.carlton@planning.nsw.gov.au (02) 4063 6611.For more information about GSNSW MinEx CRC activities, please visit: https://resourcesandgeoscience.nsw.gov.au/miners-and-explorers/geoscience-information/minexcrcStatewide 3D fault model releasedA new statewide 3D fault model has been released (Figure 2).
