SGL Completes Large-Scale Gravity Survey over AustraliaNovember 2024 - Sander Geophysics has completed an extensive airborne gravity survey over Victoria, Australia. The survey provides the State Government of Victoria with consistent, high quality, evenly distributed gravity data, including over areas that are difficult to access on the ground. According to the State Government, the new gravity data will greatly improve Victoria’s gravity model and the accuracy of real-world heights from GPS positioning, as well as aiding in the understanding of southeast Australia’s geology. State Government of Victoria (land.vic.gov.au), 12 November 2024 |

SGL Flying a Large Fixed Wing and Helicopter Survey over the Eastern USAugust 2024 - Sander Geophysics is pleased to have been selected to fly a large magnetic and radiometric fixed wing and helicopter survey over the eastern US that includes broad areas of North Carolina, South Carolina, Virginia and West Virginia. This survey will be flown between 300 to 1,000 feet above the ground as part of the USGS Earth Mapping Resource Initiative (Earth MRI) project. This nationwide initiative coordinated by the USGS will enhance the fundamental knowledge of the geologic framework of the area and according to the USGS the benefits provided include the ability to evaluate natural resources such as critical minerals, groundwater and earthquake hazards.

SGL Contributes to the New South Wales, Australia Gravity ModelAugust 2024 - Sander Geophysics is delighted to have been involved in creating NSW's statewide gravity model. Sander Geophysics flew the airborne geophysical survey with AIRGrav (SGL's purpose-built airborne gravimeter) from the end of 2022 through much of 2023. The government of NSW Spatial Services describes the benefits of this kind of model along with existing data sets as a "game changer" and also states “The future global economy and the pathway to lower emissions will be founded on minerals that NSW is rich in, such as cobalt, rare earth elements and copper” Once the work on the data set is complete the Geological Survey of NSW will make it freely available to the public.

SGL Flying a Helicopter Survey over Montana and IdahoAugust 2024 - Sander Geophysics is pleased to have been selected to fly this helicopter survey which encompasses a section of western Montana and eastern Idaho. This survey is part of the USGS Earth Mapping Resource Initiative to increase the geologic framework knowledge of the United States, and in this case within the Great Falls tectonic zone and the Montana-Idaho Porphyry Belt, with the aim to encourage exploration, and also to map faults for earthquake hazard studies. SGL's helicopters will be flying the survey in a grid pattern at about 300 feet (100 meters) above the ground and higher (1,000 feet) over populated areas.
