» Different Kinds of Sampling

First Samples. 6-inch Sampling. 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.

Integrating the Theory of Sampling into Underground Mine

Sampling is a critical component throughout the mine value chain; it includes the sampling of both in-situ and broken material for geological (resource and grade control), geoenvironmental, and geometallurgical purposes [1,2,3,4,5,6,7].Sampling errors generate both monetary and intangible losses [3,8].The data produced must be fit-for-purpose in order to contribute to Mineral Resources/Ore

Using Test Drilling to Sample Gold Deposits

Apr 27, 2016· Test drilling for gold is an important step in prospecting and eventually commercially mining for gold. Test drilling is done to get a continuous sample of the bedrock of a given gold project. The sample is then tested to determine if there is gold in the project area and to estimate the amount of gold that can be mined in the area.

SAMPLING, PREPARATION AND ANALYSIS MINING

A GOLD RESOURCE DEFINITION SCENARIO. You have identified a resource of 1.18 million tonnes of ore, which you believe to. be grade 6.3 g/t Au. That’s about 240,000 oz gold. Your calculation includes a relative standard deviation of 10%. That is 24,000 oz gold or US$36 million in gold value. That’s roughly half the cost of a 450 tpd gold plant.
