Weight. Gold is much heavier than sand, gravel, or water. When panning (or sluicing), gold is worked to the bottom of the pan (or riffles) and the lighter materials washed away. A speck of "color" sits in the very lowest point in the pan- while sand and water can be "swished" around, but the "color" sits very still- almost as if glued to the pan.
