Returning for Season 5 is Parker, who proved himself in his rookie season mining the Klondike when he brought in over 1,000 ounces of gold worth $1.4 million. This time around, he's set a lofty goal to double his take.

Todd is also back after hitting rock bottom in the jungles of Guyana, South America, where he lost his land, most of his money, and ultimately his crew.

Finally, Tony aka "The Viking," and his team return after buying a $1 million, 75-year-old floating gold dredge he hopes will be his ticket to wealth.
