The former is dant, and often found in beds of large used by miners and the latter by geoloextent. Some ores, as well as native gists and mining engineers. The five metals, are also found in alluvial deposits; gold, platinum, etc., in those known as placers. Placer products, sometimes called placer ores, have been derived from the degradation and wearing away of older rocks, the minerals having been washed out and redeposited by the agency of water.
