Dave Turin returns to gold mining, searching for an abandoned mine to resurrect and chasing the gold left behind by old-timers; backed by financiers and using his expertise, Dave is on a mission to become his own mine boss and make his fortune.

Pressure mounts on Jason to locate legendary main channel gold; but just as the operation begins firing on all cylinders, Dave faces devastating family news.

With Dave home for his father's memorial, Team Turin make a promise to hit it big in his honour, but with the Bank Cut running out, Jason must think outside the box to find new ground and keep them on the gold.

Team foreman Jason takes a huge gamble by opening a new cut, but when mishaps besiege the team, Dave returns to find them in disarray and fights to prove the Vault Cut is a risk worth taking.

As the midsummer Colorado heat bears down on the team, Jesse heads to Montana to salvage parts from the old wash plant; Dave struggles to keep the operation together for another major gold haul.

Dave calls in Freddy Dodge and Juan Ibarra to troubleshoot a faulty hopper; with the vault cut running low, a local old-timer points Dave to new gold-rich ground the old doodlebug dredge missed.
