Francis Thomson's Company Details
GPX Surveys are internationally recognised experts specialising in the collection, processing and interpretation of airborne and ground remotely sensed data. GPX offers a suite of airborne systems, both fixed wing and helicopter collecting magnetics, radiometerics, electromagnetics, altimetry, and gravity. Using these state of the art geophysical systems, we can make scientifically based calculations of the following surface and below-surface characteristics of the geological formations and nature of the regolith:• Magnetic susceptibility and depth to magnetic basement using magnetic measurements • Conductivity and relative thickness of conductive layers, such massive sulphides (copper, Nickel, etc and even seawater depths) using electromagnetic measurements from our own XTEM system • Rock Density using airborne and ground based gravity measurements • Relative content of radio isotopes using gamma ray spectroscopy
