SAM Survey Operators

HIGH RESOLUTION SURVEYS

  1. Sub-Audio Magnetics (SAM)
  2. High-Performance Transmitters
  3. Fast sampling TM-7 receiver
  4. Ground or Airborne acquisition

AIrborne SAM

Our helicopter system - HeliSAM - delivers cost-effective, regional-scale deep EM characterisation
A UAV platform is being developed which offers fast data acquisition at lower altitude

Deep Search Exploration

High-powered, deep search technology produces highest quality data

  1. Surface - SAM EM; SAMSON; SmartEM
  2. Downhole - EMIT DIgiAtlantis

SAMSON

SAMSON is a powerful, low noise, deep search technique. Stations are typically faster to acquire than SQUID or fluxgate.
SAMSON has successfully detected high conductance (Cu, Ni) ore bodies in excess of 700m below surface.

SAFETY FIRST

Gap Geophysics is committed to the health and safety of all our staff and care for the environment and communities we work in

Focus ON Quality

Our staff are dedicated to producing the highest quality data, from data acquisition and in-field quality control through to processing and final reporting

About Us

Gap Geophysics (GapGeo) is a progressive technology developer and service provider to the mineral exploration and environmental geophysics industries. GapGeo is managed by a committed group of geophysicists and engineers with over 30 years experience in development of advanced survey instrumentation and techniques.

GapGeo has developed a range of proprietary exploration techniques, with advanced instrumentation and high performance transmitters that enable greater depth of exploration and higher resolution surveys. This allows us to provide clients with better quality & less ambiguous data that are obtained in more efficient & cost-effective ways than possible with conventional instruments and techniques .

What Our Clients Say

Spectrum’s Managing Director, Paul Adams said “We are extremely pleased with the quality of the data received from our recent SAM survey at Penny West. The subsequent interpretation, utilizing all of the lithological and geochemical studies we have also recently undertaken, have contributed to a much greater understanding and appreciation of the prospectivity of the Penny West project area.”

Black Cat’s Managing Director, Gareth Solly said: “The drilling results on the interpreted SAM targets are extremely encouraging. The drilling at SAM Target 1 shows that the intersection of the NS and NE structures contains thick, high grade mineralisation. At SAM Target 2, we have identified a mineralised structure providing a clear vector towards potentially high grade mineralisation. SAM surveys are proving to be an effective targeting tool at Bulong.

“Gap provided great assistance by identifying targets for significant groundwater resources”
