Minicomputers Used in Mineral Exploration, or Backpacking a Box Full of Bits into the Bush

Recently, extensive field use has been made of a digital minicomputer incorporated into a modified geophysical prospecting method. This is a generalized induced polarization (IP) system called complex resistivity (CR) and has been successfully used in sulfide mineral exploration. The ease of use, portability and cost effectiveness of this computer-controlled method has provided a viable exploration tool based on a complex data acquisition system. Without the computer, this method would still be relegated to tedious laboratory measurements and theoretical studies.
