other various rich sedimentary sand. Detection of natural gold nuggets want to look for the metal coins,

adjusted to balance. In the ore, gold with extremely broken forms and blends in with the sands, sediment
and heavy metal ore often has a large number of signals and black metal, caused by the mixture of the
