John Schnabel net worth and salary: John Schnabel is an American gold miner who has a net worth of $5 million dollars. Now in his 90s, John Schnabel owns the Big Nugget mine in Alaska. His son, Roger Schnabel is also a part owner. His grandson, Parker Schnabel, who is just 17 years old, currently runs the family mine, and is hoping to keep it profitable so that it can remain a family-run business. The Schnabel family is part of the cast of "Gold Rush Alaska", also known as "Gold Rush", a series which follows a group of gold miners as they attempt to earn a living mining for gold in Alaska and the Klondike. "Gold Rush Alaska" debuted in December 2010 and is currently in its fourth season. Mr. Schnabel's mine has been successful for quite some time, and the other mining groups often turn to Big Nugget for advice or instruction. John Schnabel suffered a well-publicized heart attack that was a featured story line during the second season of the reality series. Recently, John Schnabel chose to retire from daily mining work but still offers his decades of experience to help guide both his son and grandson as they navigate the competitive and brutal gold mining industry.
