I am lucky where I live, alot of people drive for days to visit this mine. I am lucky to live only 3 hours from it. So I understand, seems this area is rich with minerals.
You sure can, spend the whole day digging or just walking around finding stones.
That is how it is with the beaches around here. I have talked to people who had to drive a long way to get there. I'm 10 minutes from the beach.
