Gold Rush: Dave Turin's Lost Mine - Season 4

The team divides in the remote Idaho Rockies, as half prospects historic Mores Creek and Dave helicopters into the remote back country of Warren Meadows. Then, already behind schedule, Dave is forced to make a bet that can make or break the season.

Dave gets a lead on a remote claim in Northeastern Alaska, rumored to produce major nuggets. But as he struggles up north, the rest of the team hopes to surprise him with a successful prospect at a lost mine at Skinners Ranch, Montana.

Dave's crew fights to keep their hopes of mining in the lower 48 alive with a last-minute lead in Montana. Meanwhile Dave ventures further into the wilds of Alaska where a Hail Mary prospect outside Valdez becomes his most promising ever.

Team Turin arrives in Alaska to mine their new Glacier Creek claim. But with equipment still in transit, the crew must come to grips with the aging machinery on the mine site, as rookie Andrew gets his first taste of gold mining.

One week into mining on Glacier Creek, Dave brings his high-tech wash plant The Roach into the fight to increase production. But the crew faces two new dangerous foes: flood and mud.

The team runs two wash plants at the same time, but a water pump malfunctions, turning the cut into muddy soup. Dave turns to a local miner for help as the crew tries to rally for a solid gold weigh to stay on target.

A major Alaskan rainstorm triggers a landslide that threatens Team Turin's camp. In a bid to make up on the gold, Dave has an idea that speeds up production but puts The Roach in a vulnerable position.

As Jason battles a flooded cut, Team Turin's latest super weapon in the hunt for gold, The Eagle, arrives in Alaska. But the crew must navigate the 34-ton machine across the river by creating a mobile dam.

Team Turin prepares to fire up The Eagle for the first time, when Casey receives shocking news from home. With their 600-ounce season goal in the balance, the team must double up and push forward as a skeleton crew.

Tensions mount when Dave and Jason clash on strategies to stay on the gold. And problems with the new wash plant put Chris in a vulnerable position.

With the team struggling, Dave's business partner arrives on the claim to observe the operation. But his presence creates tension when he identifies one of the miners as the weak link.

With winter closing in fast, Dave and Lance hedge their bet with a prospect in a historical mining district in the foothills of Mt. Denali. Back on the claim, the team faces obstacles from mother nature and machine, but break a long-time team gold record.

Dave tests positive for COVID and entrusts team mechanic Nathan with a solo prospect deep into the Alaskan wilderness. Back in Valdez, equipment breakdowns force greenhorn Andrew to step up and save the team's gold.

Dave gets the call from Rob Towner for a once-in-a-lifetime prospect at Gravely Ranch, Montana where he uncovers the best gold-bearing ground he's ever seen in the lower 48. But to mine it, he must earn the trust of a ranching family wary of miners.

Back in Alaska, Dave's risky move with the washplant proves disastrous. Then, with the big final push to close out the season about to begin, one crew member contemplates moving on early.

In the epic season finale, an approaching snowstorm threatens to shut Team Turin down, but the miners face down snow, ice and deadly conditions in an effort to best their gold goal.
