 Employing the concept that a radio signal is absorbed (attenuated) as it propagates through the rock and soil mass. Its speed and rate of attenuation are functions of its frequency and the electrical conductivity of the rock and soil. By placing a transmitter of a radio signal at one point and a receiver at another its possible to measure the signal loss of the path between the two points.

A radio frequency at a specific frequency travels faster and further through low conductivity media (limestone, coal, potash ) than through materials with high conductivity (shale, mudstone, clay, ore zones etc).

  • Variable Multi frequency scans capability  (Typical frequencies for the BGMS are from 2.5 KHz to 1 Mhz).

  • BGMS provides diagnostic information, often in the form of an image of the conductivity contrasts, on a plane surface in the earth.

  • BGMS is used to locate and define features in the earth with different electrical conductivity’s, which intersect a plane defined by;

Ø      Two or more parallel or existing drill-holes

Ø      Drill-holes and surface lines radiating from the drill-hole collar.
