Meltdown

Dave hits pay dirt when he gets access to an old stamp mill, a device used to crush rocks into powder to get the gold out. Diego heads to a racetrack because he thinks he might find old silver horseshoes, but when a trainer suggests he might find silver and platinum at the nearby horse hospital, he goes there instead. Meanwhile, Rich heads out to a Wild West-themed ranch used for movie shoots and weddings hoping to find precious metal antiques.
