The hopper on the starboard side of the dredge is visible. The dredge processed the gravel through jigs as opposed to sluices. With the volume of material the dredge handled, a sluice would have been impractical. A jig has a diaphragm driven by an electric motor which pulsates. The Yuba jigs were about 42 inches long by 42 inches across. A bed in the jig was filled with steel shot. As the gravel material floated across the steel shot, the jig's pulsating diaphragm raised the steel shot-bed up and gold, being so much heavier than the gravel and the steel shot, would work its way down through the shot-bed. The jig bed usually has a 1/8-inch mesh stainless steel screen so that any gold finer than 1/8 inch will pass through the screen. The jig pulsated between 60 and 100 times a minute, a "steady throb." Gold coarser than 1/8 inch, being very heavy, would be held on top the screen beneath the bed of steel shot.
