mining

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.

These deposits form a mineralized commodity that is of economic interest to the miner, and is typically done in a large scale inside a mine (place).
