The Deep Search term is applied to geophysical surveys that are particularly good at deep ground penetration. This is particularly important for mineral exploration, where it is possible to have viable resources more than a kilometre below the surface.
Historically, the depth of exploration has been limited by the capabilities of the instrumentation. By increasing instrument resolution and the power of our transmitters, we have significantly increased detection depth. Improvements to the signal processing algorithms has also offered further consistent noise reduction.
The Gap Geo survey philosophy is that we endeavor to survey with the best technology available. Our survey data is at the approximate ambient noise levels inherent to the background, and our depth of detection is down to seemingly practical mining limits. If our survey finds nothing, we know with confidence that there has been nothing meaningful missed.
The following methodologies are appropriate for Deep Search exploration:
