    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.
