    Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sortin

The recovery had two steps: bringing the gravel containing gold to the surface and then separating the gold from the gravel using water and gravity separation, as a result access to water was important since it was necessary for the separation process and could also be used thawing the permanently frozen ground and washing down gravels from the upper terraces.
