Keywords: drill, interpretation

The aim of the advanced interpretation is to outline drill targets

(drill collar coordinates, dip & azimuth, target depths)

Level 1 - Written Assessment Level Report (Included with all surveys)

  • Explanation of all geophysical products, what they mean and how they should be used
  • Structural analysis of geophysical data including vector diagrams outlining structures of interest
  • General geological summary and integration with geophysical data
  • Recommendations addressing which anomalous regions should be pursued in more detail

Structural interpretation of magnetic data included with all survey contracts

Level 2 - Written Interpretation with Geological Input

  • Full integration of all available geologic data into geophysical map products
  • Correlation of data with surface sampling records, known showings and drill results
  • Advanced product generation (Tilt derivative, RTP, 2VD) explanation and interpretation
  • Comprehensive write up with additional recommendations
  • Face to face presentation and discussion of survey results

Advanced product interpretation with geologic integration

Level 3 - Advanced 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
  • 3D modeling of drill hole results with survey data integration
  • Provided drill collar locations and/or trenching coordinates with anticipated intersections

Inversion modeling of magnetic data (Mt. Milligan deposit, Li, 1996)

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.


Mineral Exploration

CMG uses the larger volume 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.


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.
