A gold dredge is a machine that extracts gold from sand, gravel, dirt, etc., using water and mechanical methods to extract the gold. A gold dredge uses a mechanical method to dig up material (sand, gravel, dirt, etc.) using either steel "buckets" on a circular, continuous, steel "bucketline" at the front end of the dredge, or suction. The material is then sorted/sifted, using water. On large gold dredges, at the tipping point of each bucket on the bucketline, the material falls into a steel rotating cylinder (the "screen or trommel") that is sloped downward toward a rubber belt (the "stacker") that carries away oversize material (rocks) and dumps the rocks behind the dredge. The cylinder has many holes drilled into it to allow undersize material (including gold) to fall into a box. The material that is washed or sorted away is called tailings. The rocks deposited behind the dredge (by the stacker) are called "tailing piles." The holes drilled in the screen were intended to screen out rocks (e.g., 3/4 inch holes in the screen sent anything larger than 3/4 inch to the stacker
