New mining exploration system


  • Anonymous


Barringer Research, Inc., reports the use of a new exploration system which is being flown across potential mining areas in the Pacific. The system, called ‘Radiophase’ uses broadcast radio signals in the VLF band—15 to 30 KHz and measures the slight effects that subsurface structures have on the propagation characteristics of these signals. The effects are in proportion to the structure's conductivity and, hence, their possible sulphide content.
