With his trommel no longer in operation, Todd Hoffman decide to merge the two groups into one big group at Indian River, and not lay anyone off. Upon setting up, the wash plant breaks down, but they are able to use Jack's excavator to run the plant, even though no one told him. In the end, they are able to get 46 ounces.
At Porcupine Creek, "Dakota" Fred, Dustin Hurt, and Melody are finally running good, until a massive bolder breaks their de-rocker. After fixing it, they are able to get 24 oz, bringing them to a total of 104 ounces so far for the season.
