How the IP effect is useful for low conductivity minerals such as Sphalerite. Image2Dô inversion used for target selection.

The Normetal VMS deposit, one of the deepest ever mined in Canada, is located in the Abitibi Greenstone belt of Quebec.

While Sphalerite (ZnS) is a non-conductive mineral, it is often chargeable.

The Induced Polarization technique proved successful at Normetal.

Image 2DTM inversion indicated that the volume of sulphide may increase with depth. This was confirmed by drilling.
