Hot Rock ?

While detecting I got a signal on this white chalky rock but thought
 it was
just another hot rock. It sounded a little different than most
hot rocks so I stuck it in my pocket and kept it especially since it
was on the edge of a known nugget patch..

When I got back to camp I took a photo just in case and then got
a pair of pliers and cracked it open. What a surprise to find a
 shinny nugget inside it.

Here is a close up of the little nugget, curiosity sometimes pays.
We get a little wiser with each trip.
