Mining Geology Sampling Methods: Channel, Chips, Core

Drift Mine Sampling. Underground mining procedures are collectively known as "drift mining" where applied to placer gravels. Placers buried under deep masses of low-value gravel or capped by lava flows have been extensively worked in this manner. Drift mining presupposes the concentration of values in a well defined stratum or channel.
