Here we are dropping a load in the wash plant, The wash plant runs off of a two inch pump, the hopper has a vibrator motor attached to the bottom to assist in getting the dirt to slide down the hopper and fall into the sluice box, the vibration also help to break apart clumps and shake the gold stuck to rocks off.  All of our water runs off into settling ponds, you can see part of one in this picture.  We built the wash wash plant, although we will be constructing a larger one for next season, the more dirt you can move the more gold you can find.
