Does gold float in water?
Gold is hydrophobic: it repels water. Because of this, even if the piece of gold is first completely submerged, if it gets near the surface it will throw off the water above it and float. Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.
