Grab Sample - Mining Fundamentals

Grab sampling takes equal amounts of ore at selected intervals from a mine dump or muck pile. This method is not usually considered a reliable one. Other mining sampling methods are bulk sampling, channel sampling, and chip sampling. The results of all these methods are combined in order to determine the grade of the ore body.

Sampling and Evaluation – Western Mining History

7. WHEN SAMPLING FAILS Not all placers lend themselves to the usual forms of sampling and there are some which cannot be sampled by any means short of mining the entire deposit. This problem usually reflects one of two things: (1) The gold or other mineral occurrence is so erratic that usual sampling or evaluation methods break down hopelessly.

are commonly employed; 1) pumped and 2) depth sampling. Samples can be collected using a bailer but due to the volume of water that needs to be removed, this method is not commonly selected over other methods. Where these methods are thought to be inadequate or cannot be used, a variety of in-situ sampling methods may be employed.
