Open cut mining, also known as open-pit or open-cast mining, is a method employed to extract valuable minerals or rocks from the earth. This type of mining is characterised by the creation of a large visible pit or hole in the ground, as opposed to tunnelling into the earth, which is typical of other forms of mining.

Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
