In situ mining (see mining solution page) can be more environmentally friendly than underground mining and is cheaper than many mining methods (Ulmer ). However, in situ mining cannot be implemented in all cases as the ore needs to be beneath the water table (the level at which the ground is saturated with water) and it

To do this, prospectors used pans to test the surface gravels or dug straight down to a point just above bedrock where placer gold tends to collect. They then tunneled horizontally to follow the richest ground. This approach is called drift mining (the horizontal tunnel is the drift). These shafts and tunnels were typically dug in winter so
