Have anybody watched the season 3? I think they are jokers not miners. Such amateurs comparing to Bering sea gold, or gold rush (and even a Jungle gold!). They find few microscopic grains of gold and they are so excited.... here are some great comments about the show: http://www.imdb.com/title/tt2812850/reviews
I watched bering sea gold for a couple of episodes, I thought they were jokers, going out with little understanding of the sea, mechanics or gold recovery. The dredger knew what he was doing but the rest were just a danger to themselves. Still, I recommend everyone to watch an episode of it just to see the lengths people will go! Then watch an episode where they go diving under the frozen sea, then never watch it again.
