(The digging equipment may also be mounted on a separate barge or on the same barge as the plant.) Material is dug from the sides and bottom of the mining pond and deposited into the washing plant's hopper. "In certain cases, placer material is most economically excavated with a shore-mounted dragline or backhoe and a floating (barge-mounted) concentrating plant. The barge consists of a large two-story building using machineries such as pulleys, conveyor belts, buckets and cables to dredge for gold. Four men in a boat(?) are about to dock near one of the several side entrances to the gold dredging barge.
