I'm hoping to find a prospector friend like you to go Prospecting with. I bought my sluice box and detector almost two months ago and having a partner to go out Prospecting with would really be cool. It would be more fun and it's safer going into the mountains or desert (quartsite for now). Happy Birthday!
Man, be careful. What looks like an adit can be a collapsed stope or just a slump from the adit below.. There can be a "bridge" of soil and rock and then who knows how deep below it. I've checked out lots of mines in oregon. Don't mess with anything that has crumbly rock, even a nice open adit. If you hear a nice echo it is a good sign but have the right gear...Best of luck
