🧲 What is a magnetic anomaly? A variation in Earth’s magnetic field that can reveal changes in rock type, faults, dykes, buried objects & more. The key isn’t just finding an anomaly—it’s understanding what caused it. gemsys.ca #GEMSystems #Geophysics

A recent UAV magnetic survey using the GSMP-35U potassium magnetometer at the Martello Gold Project in Ontario covered more than 770 line-km to help improve the geological understanding of the project area. irw-press.com/en/update-re-m… #Geophysics #Magnetics #MineralExploration
