Follow the lives of ambitious miners as they head north in pursuit of gold. With new miners, new claims, new machines and new ways to pull gold out of the ground, the stakes are higher than ever. But will big risks lead to an even bigger pay out?

Between the third and the fourth seasons, Todd Hoffman and several crew members traveled to South America to prospect for gold in Peru, Chile, and Guyana. This was covered in several episodes, in a summer season for Gold Rush.
