Sanborn Geophysics Group has expanded its deployment of airborne Time Domain Electromagnetic (TDEM) survey systems to support critical minerals exploration. This technology provides high-resolution mapping of subsurface electrical conductivity, aiding in the identification of geological formations related to nickel, copper, cobalt, lithium, and rare earth elements.

By mapping regions quickly from the air, exploration teams can prioritize drilling efforts on promising targets, thereby reducing environmental impact. The TDEM surveys are also utilized in regional geologic mapping initiatives to create high-resolution datasets for resource assessment.
