Discovery's ambitious gold miners are back again, and mining for treasure with even higher stakes.

This season, everything has changed - new miners, new claims, new machines and new ways to pull gold out of the ground. But will bigger risks lead to an even bigger payout? 

In the first episode, the young and ambitious Parker sets an outrageous goal of 2,000 ounces, and Tony Beets - the Viking - buys a 75-year-old gold-catching dredge. Meanwhile, Todd Hoffman is left a broken man - without a crew, and without a plan.
