Such would be a great candidate for a Gold Cube which uses about 1100 gallon per hour 12 volt pump and can process from what the inventors claim up to 1000 pounds of classified material per hour or about a half a yard for such a little tool, i have not had that kind of volume yet to try to run on a timed basis, though i hope to this summer yet. From what i read your friend has rices sized nuggets/pickers which would make them able to pass through about 10-12 mesh, for the most part and an 8 mesh screen most all the time unless its really long wire type gold. While i have not built my own dredge, i have run a couple and have thought about building one a time or two or improving an existing one.
