Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits.The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total
The gold also moves more slowly. Cracks, crevices, holes and barriers in the bedrock can trap the gold out of the flow of water and material. And of course, this happens much more along the general gold path than off of it. Gold deposits along the general gold path can be small or large, depending upon the size of the gold …
