Mithril ore detail.png

Mithril ore is a type of ore that can be obtained through the Mining skill in various places throughout RuneScape. See the mithril rocks article for details regarding locations for mining mithril ore. It can be smelted with 4 heaps of coal through the Smithing skill at level 50 to form a mithril bar, which can then be smithed into various types of weapons and armour.

Mithril ore can be mined with a Mining level of 55 or higher, granting 80 Mining experience. After being mined, a mithril rock takes 2 minutes to respawn.


Mithril ore can be found in different mining sites around RuneScape such as:

Other ways of obtaining

  • Its noted form can sometimes be found inside barrels.
  • At 55 Mining, it can be obtained at Motherlode Mine from mining and cleaning pay-dirt.
  • Ordan sells mithril ore starting at 243 coins, but it may be cheaper to buy from other players instead.

Respawn rate

As of 17 July 2014 and according to the Boss Pets and Spawn Rates update:

Spawn rates of pretty much everything in Old School will now be consistent throughout all worlds...[and] resources and monsters now spawn at a standardised rate throughout all worlds regardless of how many people are currently online.
— Mods Alfred, Ash, John C, Mat K, Reach, Ronan & Weath

That means mithril ore spawns at a standardised spawn rate, which is 2 minutes after it was last mined, no matter how many players are on a world. Whether it's zero or 2000 players in a single server, all ore across the game will respawn at the same rate.
