Geophysical Exploration Continues Its Rapid Pace

Mining geophysics in 1967 continued to expand with greater application in the exploration and development of mineral deposits. Moreover, geophysical activity increased without the particular emphasis of a Pine Point or Timmins discovery to spur interest. This trend is expected to continue through 1968 as geophysics more and more becomes an integral part of a mineral exploration program. This past year saw the "little black box" of the old-fashioned "doodlebugger" pushed further into the background, replaced by increasingly sensitive equipment of sophisticated design. The trend also is away from the one man geophysical operation wherein the same individual is responsible for the development, design and operation of the field gear, the planning and execution of a survey and analyzing and interpreting the data. In today's technology a staff of specialists, electronics engineers, mathematicians, physicists-to name but a few- are required to back up the exploration geophysicist in the development of new methods and techniques, in the reduction of the voluminous amount of field data and in the interpretation of the anomalies which can be enhanced by various high-speed computer techniques. Obviously a full back-up staff of these varied abilities is impractical to most exploration companies. However, the equivalent function is provided to the lone staff geophysicist by the many competent geophysical contractors and individual consultants.
