Canadian Mining Geophysics Ltd is pleased to offer a selection of geophysical technologies to best suit your exploration needs.

Tri-Axial Magnetics with VLF-EM

The CMG airborne magnetic gradiometer and VLF-EM system is based on GEM Potassium sensors to provide the highest sensitivity available in the industry. CMG uses the larger volume (75 mm) sensors that are specifically designed for low-gradient applications such as exploration for gold, silver, platinum & palladium and mapping geologic structures that are weakly magnetic and may have concentrated precious metals.

Radiometrics (Gamma Ray Spectrometry)

CMG utilizes a state of the art gamma ray spectrometry technology optimized for high sample, full spectrum data collection. The revolutionary RSX-5 digital airborne gamma-ray spectrometer (Figure 6) is designed for the detection and measurement of low-level radiation from both naturally occurring and man-made sources. Historically, gamma ray spectrometry has been widely used for uranium exploration as a direct measurement technique. However, the use of gamma ray spectrometry to determine concentrations of the three primary radioactive elements in nature (Potassium, Uranium, and Thorium) enables alteration mapping in a wide range of geological settings. Common settings where radiometric techniques have been successful include uranium deposits, porphyry copper deposits, gold exploration, radioactive halos over hydrocarbon deposits as well as in diamond exploration.

CMG offers level one data interpretation as part of the cost quoted to you, but we have the ability to get involved in your exploration program on several different levels; from survey design to generation of drill targets. We want to become a part of your team, if only temporarily, to get the best results possible for your exploration efforts. We are currently available on short notice to mobilize our system across the country or abroad.


Geophysical Interpretation

Three dimensional inversion of magnetic data using UBC inversion or Fullagar inversion routines. Forward modeling of selected structures to obtain depth estimates and dip direction. Structural interpretation of magnetic data included with all survey contracts. Full integration of all available geologic data into geophysical map products. The aim of the advanced interpretation is to outline drill targets.


Geophysical Products

Our triaxial gradiometer allows the measurement of individual magnetic gradients providing detailed information in each axis important for precise calculations of many advanced geophysical products. At CMG, we offer a wide variety of geophysical products to our clients to add the most value to our surveys.
