Runite rocks are a type of scenery which give runite ore when mined. Level 85 in the mining skill is required to mine runite rocks, the highest mining requirement in the game. Doing so gives 125 experience when mined successfully.
A depleted rock takes between 12 and 15 minutes to respawn, depending on the population of the server.
They are by far the most scarce and inaccessible mining rocks in RuneScape Classic with only four rocks in existence, and all of them in difficult to reach and/or dangerous locations.
