The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.

Gold in Guyana—Part II: Process Optimization at Sacre Coeur Minerals' Lower Puruni Alluvial Mining Project
In Part Two of my two-part series I describe the mechanized alluvial gold mining operation on the lower Puruni River launched by Sacre Coeur Minerals in 2011.

While river dredging in fast water, don’t be afraid of being swept out of your dredge hole by the current. If this happens—and it most certainly will in fast water—there is no need to panic. Don’t try to swim against the current because you will waste much energy in an effort to conquer the river. Just let it take you downstream.
