Alluvial Gold Goldrush Mining A clean alluvial gold

Due to the dissolution of silver that accompanies gold, chemical concentration also takes place. For this reason, alluvial gold is poorer in silver content compared to strand gold. Under the action of infiltration waters, a separation of grains and golden sheets is produced, which from the surface, gradually descends to the base.

Prospecting Placer Gold Deposits

The formula for calculating the value per cubic yard represented by each drill sample is as follows: C x M/A x D x 27 = theoretical value per cubic yard. where, 27 = cubic feet in a cubic yard, C= value of gold in cents per milligram, A = area of drive shoe, square feet, D = length of sample in feet, M=milligrams of gold recovered from sample.
