Correction to the above here is part of the text from there web site.
"Recreational panning for gold is allowed on most of the Uwharrie National Forest. Stream-bed (placer) gold, in most cases, does not exist in sufficient quantities to constitute economically recoverable deposits. No fee or permit is required as long as only shovel and pan techniques are used and no significant stream disturbance results, but one should check with the Uwharrie Ranger Station. Sluice or "shaker" boxes are allowed, but no mechanized or motorized equipment, such as suction dredges are allowed."
Key part
Sluice or "shaker" boxes are allowed, but no mechanized or motorized equipment, such as suction dredges are allowed." Not just pan and shovel.
