Brief Notes on: The Economics and Benefits of Mid-sized Airborne Geophysical Survey Contractors and the Operation of and Advances in Using Geophysical Drones.

There is no doubt that one of the first and most important steps in exploration for new mineral resources should be to conduct airborne geophysical surveys which aid in geological mapping of the subsurface and even detection of potential economic mineral deposits. But what is the most economical and beneficial approach, contractors or Unmanned Aerial Vehicles AKA drones? This talk will discuss some of the critical points of both approaches from real-world experience.
