Jack Hoffman's excavator gets stranded and requires emergency surgery. Also, the crew fine-tunes its wash plant, which doubles their efficiency at finding gold.
The Hoffman Crew run night and day to get to the gold, while a federal mining inspector visits both Fred and Parker. He finds safety violations and both operations face closure.
The Hoffmans are held up by their broken excavator, Parker Schnabel totals his season's hold and hands the mine back to his grandpa, and the Dakota boys work to re-open their mine.
