Why Use SAMSON?
SAMSON is our most sensitive Deep Search technique. Under ideal conditions, it brings mineral exploration to the limits of financially feasible depth-of-interest. SAMSON is capable of recording data at the background noise level - meaning that this existing commercial technology is touching on the limits of what is achievable for information discrimination.
SAMSON was developed for high conductance ore bodies such as Cu and Ni Sulphide deposits.
What is SAMSON?
SAMSON utilises our TM-7 receiver system to perform a time-domain electromagnetic survey using a total field cesium vapour sensor. It is similar to our SAM technique, but instead acquires data through five minute acquisitions at fixed points, rather than being a moving survey.
In order to achieve extra low noise levels, surveys use one of Gap GeoPaks high powered transmitters. Developed in collaboration with EMIT, the system can operate at the very low base frequencies needed for determining the true late-time decay constant of a deep target.
Fast Surveying at Greater Exploration Depth
From modelling studies, a large conductive target can be detected at depths approaching 1000m or more, even under conductive cover.
The setup and time at each station is very low as the total field (scalar) measurement allows for the surveys to be logistically simple. In-built navigation helps ensure efficient terrain traversal. Surveys can be carried out in rugged terrain without the need for a level pad for the sensor.
The system is excellent at discriminating highly conductive targets – even when within conductive terrain. EMIT’s Maxwell software can easily model the total field EM responses.
