Resistivity / Induced Polarization

Abitibi Geophysics has continued investing to improve IP solutions. Recent innovations are IPower3D®, developed to explore through deep, conductive overburden; H2H 3D IP®, which has increased the radius of exploration around and below the hole up to 400 metres with no blind zones. In addition, today’s 2D and 3D processing and inversions facilitate the interpretation of the survey and give precise targets for drilling.

What is Your IP Challenge?

Your Requirements   Our Solutions Best Application
  • Identify gold-bearing veins with sulphides
  • Map disseminated sulphides and stringers surrounding VMS
  • Discriminate between barren and mineralized EM conductors
  • Identify sphalerite, discontinuous banded mineralization, non-conductive sulphides
  • Mapping of alteration zone and structural features controlling mineral deposition (porphyry copper system)
  • Mapping of clay minerals and/or magnetic associated with kimberlitic rocks
  • Resistivity mapping for alteration, basin depth
  • Select the best electrode array for reconnaissance, depth penetration or detail target mapping
 

Ground IP

  • Conventional dipole-dipole / pole-pole / pole-dipole gradient
  • Terrain with shallow overburden
  • Reconnaissance mapping of favourable horizons
  • Locate drill targets
Ipower3D®

Borehole IP

  • Conventional pole-dipole or gradient
  • Area with few holes or very widely (> 500 m) separated holes
  • Map the extension of a the conductive mineralized zone
  • Establish the strike, dip or plunge of a mineralized zone
  Mise-à-la-masse Ground
(resistivity only)
  • For surface mapping
  Mise-à-la-masse Cross-hole
(resistivity only)
  • For borehole correlation
  • Measure (or Map) physical properties of the bedrock units to build a synthetic model and/or to constrain IP inversions
  • Get more accurate physical property values than lab or outcrop measurements
 

Borehole IP Logging

  • Vertical, horizontal or inclined boreholes
  • Measurement of chargeability and resistivity
  • Discriminate between types of mineralization (graphite versus sulphides versus oxides versus clay minerals)
  • Resolve artificial anomalies from anthropogenic features (railroads, pipelines, fences, etc.)
  Spectral IP
Abitibi Geophysics robust Spectral IP algorithm
  • Identify zones of different types of mineralization causing an anomaly - for example, sulphides in a magnetic unit
  • Identify anomalies caused by non-economic sources like clay minerals
