'Cliff mining' is one of the most primitive types of mining, and it usually supplies minuscule amounts of ores, particularly iron and coal. 'Cliff mining' is usually performed in ravines that are either above ground or below (typically above since lava frequently spawns in underground ravines). This method is carried out by creating a staircase to one of the ravine's various overhangs.
