About Geotronics

Who are we?

Our ethos at Geotronics is 3 things:

  1. We are enjoyable to deal with – We like people and we make the process easy.
  2. We are trustworthy – We are trusted advisors to our clients.  Only trust makes this possible.
  3. We deliver top quality work – We have experience, knowledge, and a hunger to provide the best work with the most cutting edge techniques.


Founded in 1968, Geotronics is headed by David Mark who has over 46 years of experience in mining exploration, geotechnical, and environmental geophysics.

David began his work in the mining industry in 1959 as a prospector then graduating from the University of British Columbia in 1965 with a major in Geophysics and a minor in Geology. His knowledge of geology is unusual for a geophysicist.

Geotronics itself was founded in 1968 by Tom Rollston. David took over as chief geophysicist in 1969 and exploration manager in 1970, assuming more and more of the roles within the company and purchasing the company outright in 1972.

Geotronics began by offering a wide variety of services, including seismic, magnetic and various types of EM, gravity, and soil sampling surveys (including MMI), as well as many others – all of which are still offered today. In 1970 Geotronics was employed to do extensive seismic work for BC Hydro on the Moran Dam site and has continued to work with BC Hydro for a number of decades.

Further, the company has extensive experience in a wide variety of climates, elements, and terrains having worked year-round in: temperate and conniferous forests, borreal forests, alpine tundra, prairies, frozen conditions and extreme cold (well below 0), deserts, and in mountainous conditions.  That includes having conducted surveys on every inhabited continent with the exception of Australia.

Geotronics is well known not only for the quantity of surveys it offers, but the extensive experience it has compiled in all these areas. This allows for a very holistic approach to the surveying work in its mining exploration, geotechnical, and environmental fields.



Reports & 43-101s

At Geotronics, we pride outselves on the quality of our reports. Both their technical quality, but also their accessibility to a non-technical reader.

And this isn't just our opinion. We've written hundreds of reports, and in our home province of BC are one of the top report submitters.

We also pride ourselves on the variety of techniques we employ. We are constantly searching for new techniques, whether that's playing a role in the development of induced polarisation, being an early adopter of MMI soil sampling, or our incorporation of 3D surveying and analysis. Our goal is getting our clients accurate results, however possible.

Over 45 years of exploration experience.
