      • Airborne FTG for mineral exploration

      See the geology beneath the surface.

      Mineral systems are shaped by structure, density contrasts, alteration, and lithology. FTG helps reveal those patterns by measuring subtle changes in the gravity field, giving geoscientists a richer view of faults, contacts, intrusive bodies, basins, and potential mineralised zones.

      FTG is frequently used to support:

      • Regional geological mapping 
      • Prospect targeting
      • Fault and contact-zone detection
      • Challenging terrain, remote areas, and urban environments
      • Rapid data acquisition when decisions need to move quickly

      Airborne Gravity for Mineral Exploration

      Unlike other geophysical methods, FTG responds to density contrasts in the subsurface, revealing faults, folds, and shear zones across entire exploration districts. From regional surveys that build geological understanding to high-resolution infill surveys that refine drill
      targets, FTG supports exploration at every scale.

      Why Density Matters

      Different rock types, structures, alteration zones, and mineralised systems can create measurable density contrasts. FTG captures the rate of change in gravity caused by these subsurface variations, helping exploration teams interpret geology with greater confidence.

      How Data is Acquired

      Bell Geospace operates three Basler BT-67 aircraft equipped with full tensor gravity gradiometry technology, scalar gravity, and magnetics. They are designed perfectly for long range and low flights and are especially adapted for low noise and low impact.

      Structure Mapping 

      The search for metals requires exploring geological structures that are often under deep cover, difficult to reach or occur as subtle extensions to known deposits.  FTG maps these structures allowing evaluation of their connectivity to known geological trends and prospectivity....
