Hey Mark, glad you got something out of that rock, cool. I picked up another two bigger bits yesterday that were also giving off a signal. One piece was about fist sized and similar to the one from our day together, the other is a lump of quartz about half the size of an aussie football. I may have to send all my pices up to you for crushing and panning, i'm getting quite a collection here now :lol: :lol:
