Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
Gold (19.30 grams/cubic centimeter) has a much higher density than copper (8.94 grams/cubic centimeter), so if you can successfully pan the copper you will have little trouble panning gold.
