Consider that in a commercial placer the relative amount of gold (by volume) may be on the order of one part gold to a hundred-million parts of gravel. To the mineral examiner this means that a single fly speck of gold in a pan of gravel is equivalent to say, 2 to 5 cents per cubic yard, depending on the exact size of the speck.
