Sir t_hunter44, thank you for sharing your precious knowledge to us and taking time to protect this group from misleading THs. Sir what i am trying to tell mathew633 is that it might be a gold aura(blueish gas form) but it is just a possibility. Sir it would be best if you can consult a geologist friend which i am sure that you have, so he confirm or refute this newbie theory and please include the radiation effect of a ton of gold to its surroundings like soil. It will be very helpful to all of us. thanks a lot sir.
Mathew363, regarding your latest pics, is the soft spot in triangular shape? then the rest is hard rock?
