Surface time-domain EM (TDEM) is the primary geophysical method for the exploration of base metals, precious metals, carbon based minerals and energy exploration. TDEM surveys are an essential tool for any conductive mineral exploration program.


  • Base Metals: Copper, Iron, Lead, Nickel, Zinc
  • Precious Metals: Palladium, Platinum, Gold, Silver
  • Carbon Based Minerals: Coal, Diamonds, high grade Graphite
  • Energy Exploration: Uranium


  • In Loop: This technique involves laying out a large transmitter loop and recording the EM response along grid lines inside the loop.
  • Fixed Loop: This technique involves laying out a large transmitter loop and recording the EM response along grid lines both inside and outside the loop.
  • Moving Loop: This technique uses a transmitter loop and an EM receiver. The receiver takes a measurements inside the loop and then the loop is moved and the process repeated.
  • Slingram: This technique is the same as moving loop but EM measurements are made both inside and outside the loop.


IES uses the instruments and software developed by ElectroMagnetic Imaging Technology:

  • SMARTx4 Geophysical Transmitter: The SMARTx4 is EMIT’s next-generation quality EM transmitter system for reliable, efficient and safe operation.

  • SMARTem24 Receiver Systems
    : The SMARTem24 is cutting edge technology with 24-bit ADCs, up to 16 channels, GPS synchronization and the powerful SMARTem signal processing.

  • SMART Fluxgate
    : The SMART fluxgate is a solid, hard wearing platform integrating accelerometers for orientation measurement. Accurately calibrated for orientation and sensitivity, they are fully compatible with SMARTem24. Geomagnetic field (total and vector) measurement is also available.

IES uses Maxwell software to process and interpret EM data. Maxwell is industry-standard for dealing with EM geophysical data whether it is time-domain, frequency-domain, ground or borehole.


​​IES is primarily engaged as a turn key geophysics contract company. We also subcontract and partner with large national and international geophysics companies, work as 'in house' crews and we often train Client and Government employees how to properly conduct geophysical surveys for themselves.
IES was the primary geophysical contractor for Hudbay Minerals from 2009-2014. During this time IES engaged up to 50 personnel and gathered over 300,000 meters of borehole EM and 1000 kilometers of surface EM.
