The ambitious gold miners are back at it again and the stakes have never been higher. This season, everything has changed – new miners, new claims, new machines and new ways to pull gold out of the ground. Returning in Season 5 is Parker Schnabel who proved himself in only his rookie season mining the Klondike, raking in over 1,000 ounces of gold worth 1.4 million dollars. Last season, Todd Hoffman hit rock bottom after braving the jungles of Guyana, South America, in an attempt to make a fortune along with his father Jack, Dave Turin, Jim Thurber and the rest of the Hoffman crew. This year, Todd is back at square one. Meanwhile, Tony Beets and his crew dive in full-time to take on the unthinkable. Tony, known throughout the Klondike as “The Viking”, buys a million dollar, 75-year-old floating gold dredge. But to resurrect the gold catching monster, he needs to take it apart piece by piece. Can “The Viking” resurrect the machine capable of pulling millions out of the ground or will he be left with a 1,000 metal pieces of junk?
