Induced polarization detects a gold deposit and Image2D™ illustrates an increase in sulphides at depth
![]() |
This Ontario lode gold deposit is situated on a geological contact zone, beneath a layer of conductive overburden. |

The IP pseudo-section clearly shows a large anomaly between station 0+00 and 1+20S. The resistivity pseudo-section displays a more complex image. Additional interpretation is required to plan an efficient drilling program. |

The Image2DTM resistivity true-depth section locates the geological contact more clearly; The Image2DTM chargeability section distinguishes the deposit south of the contact zone and illustrates that sulphide content increases with depth. These results were confirmed by drilling |
