What about making a magnetic blanket to drag in a gold-bearing river? Then take the black sands (magnetite) and process them for any possible gold? People save the black sands from their concentrates usually because they are just timid about panning the very small Gold out of the black sands (Hematite and Magnetite) in the concentrates.

The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron. Other precious metals were also used mainly for gilding or coinage. Initially, many metals were obtained through open-pit mining, and ore was primarily extracted from shallow depths, rather than though the digging of deep mine shafts.
