Hoov, Deputy beat me to the punch with that request...thanks Deputy. Great lay out in laymans terms, thanks, My question, would it be possible to set up a subsurface grid, surround the target in question with sensors in existing drill holes, then have a receiver placed down hole certainly central and well above the circular array of sensors, is this being done, can or could it be done?

These discussions on Z-TEM, most seem to be using it around the ROF, have peaked my interest, in the Vanadium news release there's mention of the use of Ground Magnetometer technology. I found a site which explains it quite well i think, link below, a good read, especially the sections on multisensor and advancements in this type of technology.
