Sander Geophysics to Resume Flying in IrelandJune 2024 - Sander Geophysics will be flying a high resolution geophysical survey during the summer over the counties of Kerry, Cork and parts of Limerick as part of the Geological Survey of Ireland's ongoing Tellus project. Dr James Hodgson, Geological Survey Ireland and Tellus project manager, says: "With over 80% of the island already covered, our team is looking forward to tackling the remaining portion of this substantial project. The airborne data already produced has helped us to improve our geological maps, enhance radon risk mapping and facilitated new research on environmental pollution, agricultural productivity, and the study of peatlands."

AIRGrav Data to Improve Geological Knowledge and Refine the Geoid Around Melbourne, AustraliaFebruary 2024 - Sander Geophysics is flying a high resolution magnetic and gravity survey over the Melbourne area as part of a larger project covering parts of Victoria and South Australia. The survey is being flown with AIRGrav, which is SGL's purpose-built airborne gravimeter. Susan Haydon, Senior Geophysicist, Geological Survey of Victoria states that the aim of the survey work is to "build a more consistent and accurate map of Victoria's gravity to improve the vertical precision of GPS and our understanding of the state's geological architecture."

Australian Gravity Data ReleasedOctober 2023 - Preliminary gravity data acquired by Sander Geophysics for the Geological Survey of Victoria and Geoscience Australia have been released. Gravity grids covering areas of Greater Melbourne and eastern Victoria can be downloaded from Earth Resources Victoria or the Geological Survey of Victoria Catalogue. Further processing is going to be performed on this high quality preliminary data, so minor updates are to be expected when the final data are released. Haydon, S.J./Bates, M., 2023.

SGL Flying a Helicopter Survey over Southwest MontanaJuly 2023 - Sander Geophysics is pleased to have been selected to fly this helicopter survey which is located around Butte, Montana. The Montana Bureau of Mines and the US Geological Survey are collaborating on this project and have identified this area for further study due to its mineral potential. The preplanned lines will be flown at 80-100 metres (260-300 feet) above the surface and around 1,000 feet over populated areas. This survey is part of the USGS Earth Mapping Resource Initiative to increase the geologic framework knowledge of the United States and initiate exploration in areas deemed to have potential for undiscovered critical minerals.

SGL Flying Large Survey over Iowa, Nebraska, Minnesota and South DakotaMay 2023 - Sander Geophysics is thrilled to have been selected to fly a magnetic and radiometric fixed wing survey for the USGS over the Spirit Lake tectonic zone, which encompasses parts of northwest Iowa, northeast Nebraska, southwest Minnesota and southeast South Dakota. According to the USGS, this survey will better map the Precambrian rocks at depth and help to evaluate the potential for critical mineral deposits in the area. Once the final data compilation is complete the information will be made public. USGS (usgs.gov), 10 May 2023 |
