Sander Geophysics is Back in IrelandMarch 2025 - Sander Geophysics is very pleased to have resumed flying high resolution multi-parameter geophysical surveys in Ireland, with flights this season planned over the counties of Kerry and Clare using two of SGL's Twin Otter aircraft. This current campaign is part of the Geological Survey of Ireland's ongoing Tellus project to collect geochemical and geophysical data across Ireland. Minister Darragh O’Brien said: “By the end of the survey, we will have flown all the far corners of the country and everywhere in between, collecting detailed geophysical data. The airborne data is being used to improve our geological maps and search for critical raw materials.” Press release: Geological Survey plane collecting geophysical data in Kerry and Clare in 2025 Government of Ireland (gov.ie), 20 March 2025 Survey plane collecting geophysical data in Clare The Clare Herald (clareherald.com), 20 March 2025 Tellus survey to fly final phases over Kerry and Clare Agriland (agriland.ie), 20 March 2025 |
