sayed gold values, and as late as 1945 recovery of free gold averaged only 70-75% (Spiller, 1983). Moreover, it is likely that most remaining placer deposits have a higher percentage of fine gold than placers worked during the gold rush. It is understandable, then, that today more care is given to the re-covery of fine gold.

I have had a lot of success with the Fine Gold Sluice Box, catching this "fine stuff", but there are many ways to target lighter gold particles. Another good way is to slow down the flow through your sluice and classify your shoveled materials down to 1/4" and smaller. What I am actually aiming for using this method is to catch black sand.
