Copper Scrap And Mill Sampling Technique

Mining Geology Sampling Methods: Channel, Chips, Core

Assuming ideal conditions and a perfect core, the value of the hole (or the sample increment) would be determined by use of the following equation: cents per cubic yard = W x V x 27/A x D. in which W = weight of gold in milligrams. V = value of gold in cents per milligram. A = effective area of drive shoe in sq. ft.
