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 ...
Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870.. The modern form of hydraulic mining, using jets of water directed under very high pressure through hoses and nozzles at gold-bearing upland paleogravels, was first used by Edward Matteson near Nevada City, California in 1853 during the California Gold Rush.

Gold mining is one of the most common uses for the staking of mining claims. In Alaska, state mining claims may be up to 160 acres (0.65 km 2), and there is no distinction between lode or placer claims. The boundaries of the claim must follow the 4 cardinal directions, with an exception being adjustments for existing valid claims.
Nevada City is twinned with Penzance, a seaside town in Cornwall, UK, and the nearby tin and copper mining town of St Just in Penwith, Cornwall, UK. [52] The twinning is a result of Cornish migration during the Californian gold rush in which Cornish mining expertise migrated to the area.
The gold uncovered from the town's underground river channels and placer mines contributed to the Union's success during the American Civil War. [36] Chili Gulch was the richest placer mining section in Calaveras County. [37] Mokelumne Hill was the richest placer mining section of Calaveras County and one of the principal mining towns of ...
