Iron rocks are a protruding rock containing iron ore. A player with a Mining level of 15 or higher can mine iron ore from rocks found in various mines, granting 35 Mining experience for each ore mined. After being mined, an iron rock takes 5.4 seconds to respawn. When inside the Members' area of the Mining Guild, an iron rock takes 2.4 seconds to respawn. The faster respawn time makes it the best place to powermine iron, with an experience rate around 67k xp/h.
There are currently 14 locations in Runescape that have three iron rocks in a triangle formation.
A gem table has a 1/256 chance to roll instead of the main drop table.[1] If the player is wearing a charged amulet of glory, amulet of glory (t), or amulet of eternal glory, the probability increases to 1/86.[2][3] If the table successfully rolls, the player may receive an uncut gem or nothing, meaning players can receive no items from a rock even if they were guaranteed to receive an ore in the main drop table.[4] This neither depletes the rock nor grants mining experience.
The probability for a player to receive an iron ore drop is shown for varying levels in the figure below.[5] The rock will deplete after receiving the iron ore.
