the electromagnetic enomaly

ARe there any geos out there that can lead us in the right direction as to what the electromagnetic enomaly may be in gold bearing country around tennant creek.

Using this form of technology the old gold miners never had in the early days.

Could it be more gold, iron, copper nickel, PNG,

I myself have no idea ( just have it in my head that it may be a massive amount of gold in a large deposit) but i could be right off the track on this one.

Anyone have a better idea of what it may be????????
