Very cool, thanks for sharing! When I was at 29 Palms I had a friend who was a geology major and he built a contraption that fit in the back of his pickup to enable him to rapidly pan for gold in the streams of Joshua Tree. When we first arrived in Okinawa we were brainstorming how to leach platinum out of catalytic converters using chemical baths, but the automotive centers on base wouldn't sell us cats so that idea died. I think he went back to get a Masters in Petroleum Engineering and then wanted to move into undersea robotic mining. I can see how it can become an addictive yet rewarding hobby.
