For the last two years we’ve held a hands-on prospectors training session in the Iowa Hill district of California’s Mother Lode country as a part of our Gold Prospecting and Mining Summit event.

I love it when I am in the middle of a high trash area and all the ferrous bars go away, the screen number goes to a three or an eight, and the meter is forty to a hundred. I don’t know for sure that I have found gold, but it narrows the odds down.
We split up in order to cover a larger area and found good color almost everywhere. The bedrock was shallow on both sides of the river, but the inside bend was where we concentrated our prospecting.
I got a signal but knew it was small. Still, I was very happy to find something. I continued and got another signal. Yes! A bigger nugget! Then I got another signal.
