Different Kinds of Sampling - New 49ers Prospecting Club

Sampling is a careful, organized method of attempting to locate high-grade mineral deposits; and then, obtain a reasonable perception of the value they contain. Here are a few basic sampling principles: 1) The larger the sample, the more accurately the sample results will represent the larger volume of material that has not been analyzed.

Sampling Methods | MINING

GRAB SAMPLING This method can be used on a stope after blasting at a mine car or in the transportation of ore. This work faster than chip sampling. Samples taken at random. This method also does not provide a thorough overview that can represent the existing ore deposits. 3. BULK SAMPLING In bulk sampling, samples are taken in large quantities.

Sampling practice and theory

Once the shinny content is verified as gold, then further sampling may be justified. To begin with, mark the location of the samples on a contour map, such as a USGS topo map, and delineate the area to be sampled, realizing that it will be in the drainage area, which is located at the lower elevations on the map.
