Quarrying is the cutting or digging of stone, and related materials, from an excavation site or pit and it usually leaves behind a large hole in the ground. An ore is a deposit containing an economically viable amount of a mineral, which itself is a crystalline inorganic compound, usually containing a metal. It is the metal that is of value.
