KBM Resources Group has extended its services in 2019 to become a full-service provider of fixed-wing aeromagnetic geophysical surveys. All geophysics equipment and designated aircraft are wholly owned and operated, providing customers with the ultimate in tailored service and flexibility. KBM strives to be the best value service provider for worldwide aeromagnetic surveying. Services include logistics, data acquisition, data quality control, final data processing and geophysical interpretation.
With the capacity to assemble field teams consisting of geophysicists with utmost international exposure and flight crews with thousands of hours of survey time, KBM is ideally positioned in the industry to optimize the outcome of your project.
Data quality control is performed daily on-site. Final data processing is completed in a timely manner using data processing techniques compliant with Geological Survey of Canada (NRCan) standards.

AIRBORNE GEOPHYSICAL SURVEY AIRCRAFT
KBM’s Piper Chieftain has been equipped with a Lake Central Air Services (LCAS) tail boom installation to support the magnetometer installation. The boom is specifically designed for the Piper Navajo series (including Chieftain) and the installation is authorized by Supplemental Type Certificate (STC).
FCAR is operated with a compliment of 2 flight crew, full fuel and all necessary survey equipment for each flight.
Rabbit Mountain Geophysical Case Study
- Data Acquisition
- Processed Data
An ambitious project to survey Rabbit Mountain, in North-West Ontario, was designed to test out the capabilities of our pilots and our fixed wing system.
Our pilots flew the stringent flight plan very well on the first pass.
The southern end of the plan was flown near perfectly and the northern end had some minor deviations that could be easily fixed with reflight passes.
The acquired data were corrected and analyzed.
Following industry standards, Residual Total Magnetic Field and the First Vertical Derivative of Total Magnetic Field were derived. The final derived data are to industry standard and would be ready for delivery to a client for interpretation.
