For all those that may be interested in knowing the finer details of resistivity and how it may affect their fortunes!!
I did a bit of reserch and came up with the following 4 links all courtesy of wikipedia.

https://en.wikipedia.org/wiki/Vertical_electrical_sounding
https://en.wikipedia.org/wiki/Electrical_resistivity_tomography
https://en.wikipedia.org/wiki/Magnetotellurics
There are many more arcticals just follow the "Notes"
