MAPPING INDUCED POLARIZATION WITH NATURAL ELECTROMAGNETIC FIELDS FOR EXPLORATION AND RESOURCES CHARACTERIZATION BY THE MINING INDUSTRY

[摘要] In this quarter we completed the manufacture and bench testing of the first prototype of the MT-24/LF system to be used in the natural IP survey. The MT-24/LF will dramatically reduce field costs by simplifying field operations through the use of high accuracy GPS synchronization between wide band high accuracy (24 bit) autonomous recording systems. The simplification of field operations comes about from the elimination of the need for long lengths of telemetry cable and also from the elimination of trained operators for field data acquisition. Instead, all data is now synchronized by GPS and recorded to compact Flash media which is quickly and efficiently recovered and brought back to base for processing.
