Exploration of mineral deposits

Exploration of deposits is the classic field of geophysics. The methods have been adapted to investigate also the small-scale deposits of the industrial minerals like sand, gravel and clay.
We have completed more than 150 geophysical investigation for the mineral industry.

The methods - mainly resistivity - allow a fast and cost-effective investigation, especially over large areas.  The principal objective is always to reduce drilling to a minimum.  Volumes of overburden and raw material can be calculated.
