The SSW Probe Sulfides, Susceptibility, Waste

Your New High-Tech Weapon to
Reduce Blasting and Dilution in Exploration
Holes and Production Holes

The SSW is a light, portable and efficient electromagnetic instrument which independently measures the content of conductive and/or magnetic material in the ore of a production hole. It can even measure conductive bodies in a magnetic environment, and vice versa.

The SSW probe directly measures three parameters : the relative conductivity (HFR - conductor content), the intrinsic conductivity (Rt - conductor quality) and the relative susceptibility of the material (MAG - magnetic content).

  • The HFR value (High Frequency Response) represents a specific reaction of the high frequency, in hertz, to the presence of a conductor near the probe. The HFR gives the quantity of conductive material (relative conductivity).

  • The Rt value (Ratio) indicates the quality of a conductor and is independent of the quantity of present material (intrinsic conductivity). The Rt is unaffected by the quantity of conductive material and qualifies the conductor based on a scale between 0 % (poor) to 100 % (excellent).

  • The MAG value (Magnetic) represents a specific reaction of the probe, in hertz, to the presence of a magnetic body, in particular one containing magnetite (relative susceptibility).

Below, a Falconbridge crew (Steve Falconer and Chris Morley) logging 4 1/2" production holes with the SSW system at Craig Mine, Sudbury. Please see Documents for a presentation explaining the concept.

Logging diamond drill holes in several nickel mines has demonstrated that the ore content (nickel, copper, cobalt, PGM), as assayed in the core, is proportional to the intensity of the probe’s electromagnetic response that we call HFR.

By lowering the probe in a blast hole, a profile of the ore content is instantly measured and recorded from the intensity of the probe’s electromagnetic response (EM).

The probe also measures the intrinsic conductivity of the sulphides and the percentage of magnetite.
