Things You'll Need
Instructions
Build a framework of the gold sluice of either metal or wood. Cut a flat piece of light sheet metal 16 inches wide and 36 inches long. Use a hammer and flat surface to create a bend on both long sides of the sheet metal two inches from the edge. The final product will look like a broad U-shape with two-inch walls on each side.
Line the sluice box frame with rubber matting. Look for a ribbed rubber material that will catch the heavy gold. Some door or car mats fit the description, although the prospector will need to shop around for the ideal rib pattern. Look for ribs of about an eighth of an inch for work in faster water with less of a rib used on slower moving waters.
Place a cover of ̶0;miner̵7;s moss̶1; over the rubber matting. Miner̵7;s moss is commercially available, but an effective substitute can be found in the door mat department of many home improvement stores. Look for a material that resembles an open rubber mat made of smaller strands woven or intermixed in a mesh pattern.
