In contrast to lode deposits, placer deposits are much more accessible and require less specialized equipment and knowledge to mine. Placer deposits are created when gold is eroded from its original lode deposit and concentrated by the forces of water, wind, or gravity. Placer deposits can be found in streambeds, river channels, and other areas where the …
