here is something that each of you should try
get some gold. don't need much even a ring will work , put it on the table.
tie your wedding ring or someother gold ring to a cotton thread and hold it above the gold on the table. see if the ring will slowly start to swing in a circle around the gold. not everyone can do this but my good wife (caz) can gess who now has to come prospecting with me.
it will be walk up creek till you come to a crack instead of scraping out now all I have to do is get caz to suspend the ring over the creak and see if it starts spinning.
