After a record one-million-dollar season last year, Team Turin have been hit with nothing but obstacles. Failing to find good ground in six states during the off-season, Dave and his crew must compete against prospectors grabbing claims at a record pace in a new recession-driven gold rush.

Join the adventure in an all-new fourth season of GOLD RUSH: DAVE TURIN'S LOST MINE on Friday, May 20 at 9PM ET/PT on Discovery and discovery+.

With the clock ticking, Dave and team have a new secret weapon - a mobile wash plant they call "The Beetle" to help them reach more remote mines. However, in a string of disappointments, Team Turin rallies and must decide whether or not to gamble on the biggest unknown claim of all - in Big Sky Country, Montana.

Facing not only tough competition, the miners are challenged at every turn with health issues, floods, avalanches, and dangerous wildlife before they can even get a scoop of paydirt. Can they break their previous gold record?

Payday is coming.

When pandemic travel restrictions make mining in Alaska impossible, Team Turin sets their sights on Colorado. Determined for redemption and armed with a top-of-the-line wash plant, the crew begins to dig at an American lost mine with huge gold potential. With the price of gold at an all-time high, Dave's dream of reaching financial freedom seems possible until tragedy strikes the gold claim.

GOLD RUSH: DAVE TURIN'S LOST MINE premieres Friday, March 19 on Discovery and stream the first two episodes on discovery+, the definitive non-fiction, real-life subscription streaming service, following the GOLD RUSH season finale. The following week, new episodes will air at 8PM ET/PT.

With the Rocky Mountain summer heat on their backs, Team Turin's search for legendary ‘main channel' gold is their most epic to date. Facing local resistance and the toughest ground they've ever mined, the crew must dig deep. But by looking to the lessons from history and using their seasoned skills as lost mine detectives, they soon begin to strike big hauls of gold. But success turns bittersweet when a devastating turn of events shake the crew to their core. Dave must find a way to move forward and keep the dream alive in order to achieve the record-breaking season he wants to give his crew.
