Resistivity Tomography:
This is a 120 Channel Resistivity Tomography system. It is one of the longest survey array’s available allowing for survey lines up to 1,200 meters survey length. Array configuration can reach depths of up to 500 meters below ground level for gold exploration in difficult terrain.
2 sets of 120 channels detectors Multi-Electrode Resistivity Survey System. Multiple function in one machine: The instrument has four functions including long lead IP instrument, 2D high density resistivity meter, 2D high-density IP instrument, and medium-power short lead transmitter.
1 rectifier 3Kw, 1 Honda 1800 W generator as well as connection/communication cords, 1 testing board, 1500 meters of cables, connectors, 60 used batteries, spare fuses, spare resistors, 1 Hilti 7E 7OATCC Performance Package Combi-hammer with hammer drill bits and pointed chisel, fieldwork tools, etc.
Processing and Imaging Software includes an Inversion Software specifically developed for this equipment. In 2010-2011 further developed software in collaboration with the University of Alberta.
