In placer mining, there are fundamentally two kinds of sampling: 1) Discovery: Attempting to locate a higher-grade deposit of value inside of a larger volume of lower-grade material. 2) Quantification: Extracting and analyzing smaller portions, to gain a perception of how much value exists within a larger volume. The general concept behind sampling is to minimize investment …
