Approximately 70 flakes (2 grams) of gold in its natural form were found in a concentrated area intermixed in a field of lead shot and sand at the south end of the site.

Of West African gold dust on board the Concorde. According to Lt. Ernaut, for example, in addition to the 516 slaves, "fourteen ounces of gold in powder" was taken aboard in Judas.
