Geophysical surveys measure variations in the Earth's physical properties such as magnetic susceptibility, radioactive element concentration, and conductivity. Any change in the Earth's near-surface that causes a measurable change in these parameters presents a potential application for airborne geophysics and its many uses. While not all mineral deposits respond directly to geophysical exploration methods, most mineral deposits are associated with mappable geophysical features related to geology, mineralization, alteration, and structure that help exploration managers increase their chances for success. With modern computer systems, radar/laser altimeters, GPS positioning, high sensitivity sensors, innovative data processing techniques, and skilled interpretation, airborne geophysical data are often superior to ground surveys at a much lower cost and with no environmental impact.
Precision GeoSurveys Inc. has experience in providing ground and airborne geophysical surveys across North America and globally. From our head office in Vancouver, British Columbia, we have worked in mountains, rain forests, frozen tundra, and deserts around the world. Most of our experience has been in the collection of airborne magnetic and radiometric data for mineral exploration, where we have earned a good reputation for providing cost-effective and reliable surveys in remote and mountainous terrain. Geophysics can be a very significant asset to mineral exploration decision makers, especially for early to mid stage projects.
Different geophysical methods measure different things. Therefore, not all geophysical methods are suitable for all exploration projects. Basic knowledge of the geology of the exploration area and the type of mineral deposit being sought are critical. Let us show you how to maximize your exploration investment, by helping to plan your survey and choose the right technology.

As a geologist with 40 years’ experience, I understand the challenges that mineral exploration managers face every day. Every time a new mineral deposit is found, the next one will be more difficult to discover because it will be deeper and more remote. Exploration projects and even companies can succeed or fail by the decisions that their geologists make. Having timely, high quality data from state-of-the-art technologies is critical for exploration success. Airborne geophysical survey technology is now an indispensable tool in mineral exploration, however, the best technology is only as effective as the skill of the pilot operating it. As a helicopter pilot for 30 years, I understand what is needed to safely and accurately produce quality data from complex airborne survey technology in difficult terrain. Precision GeoSurveys is dedicated to combining the best technology available with safe and precise flying procedures, to help our customers make better business decisions. I set the highest standards for the quality of work we do, and I take pride in the reputation we have earned for meeting those standards. – Harmen J. Keyser, P.Geol., President
