Unlock Subsurface Mineral Exploration Data With Electromagnetic (EM) Surveys

Contact SJ Geophysics to get started.

What are controlled source electromagnetic surveys?

Controlled source electromagnetic surveys use the principals of electromagnetic induction to measure the electrical properties of the ground. EM data is acquired by transmitting a time-varying signal that induces currents in the ground which are then detected by a receiver unit. The induced currents in the ground are generated by the transmitter using either a surface loop or a grounded wire dipole. The measured response provides information on the subsurface distribution of rocks and minerals whose electrical properties are known to span many orders of magnitude.

Key Features And Benefits Of EM Surveys

Low-Impact Survey Method

Based on the principals of induction, no ground contact is required by the receiver units or transmitter.

Specialized Techniques

Wide variety of EM techniques are available including ground, borehole and airborne options.

Conductive Deposit Identification

Ideally suited to identify conductive bodies within resistive host rocks.

Precision

EM is successfully used to identify conductors such as highly conductive nickel deposits, massive sulfide deposits, conductive brines in search of lithium, graphite, and buried metallic cultural objects.
