As can be seen in [25], it is difficult to reduce the peak transient grounding resistance (P-TGR) value by increasing the number of the grounding electrode or improving the topology of the grounding system at the assumed ground conductivity and permittivity.

As the Crazy Creek Zone is covered by overburden, and only known from geophysics and limited historical drilling, a ground conductivity survey (EM31) was completed over the Zone in 2003 to determine if the intersected mineralization outcrops on surface, to better define the extents of the near surface mineralization and to help constrain the planned trenching program.
However, increasing the relative permittivity will result in a longer TGR lasting time, while the increase of the ground conductivity can both decrease the peak value and the TGR lasting time.
