Yes, it is fun to speculate what is going on at depth. Great Fun!
Do you know how deep that geomag imaging goes? I keep thinking that red and purple on the map might indicate that those yellow gold bars may join down under. Thats probably crazy but it is either that or a echo from the surface metals. I assume they can get readings at whatever depth they want and if they can do that I have to assume there is more to the picture than we are seeing now.
Feel free to pick this apart as I am not an authority on the subject.
You may have to raise your stink bids.
