Mining is a gathering skill that allows players to extract ores, gems, rune essence, geodes, and other resources from rocks throughout RuneScape. Mined ores can be smelted at a furnace, turning them into bars that can be made into metal objects using the Smithing skill, Construction skill, or Crafting skill. Gems and geodes can be cut utilising the Crafting skill.

Walls within the 49 tiles (7x7) of a cave entrance cannot be mined. Be careful, as mining without supports may cause a cave-in that can cause HHP and SHP damage and will kill you if you get hit by too many. Mining drains stamina based on the type of the tool used, it's quality and the hardness of the tile relative to a character's mining ability.
