| Description | Procedures for placer samples involved gravimetric recovery of visible gold and platnium was performed on the sediment samples and the remaining concentrate was ground to 140 mesh. ICP spectroscopic analysis was peformed to determine the elemental composition of the concentrates. Further analysis by atomic fluorescence spectroscopy was performed to deterimine the quantity of gold and platnium group elements in the placer concentrates. |
