|“||Mithril! All folk desire it. It could be beaten like copper, and polished like glass; and the Dwarves could make of it a metal, light and yet harder than tempered steel. Its beauty was like to that of common silver, but the beauty of mithril did not tarnish or grow dim.||”|
–Gandalf in The Fellowship of the Ring, A Journey in the Dark
Mithril ore can only be found in the Misty Mountains (this includes the Misty Mountain foothills) at layer 16 or below. Every chunk in the Misty Mountains has a one in four chance of spawning a Mithril vein. Each vein can be up to six blocks in size, which leads to an average of 2.2 Mithril ore per ten-thousand blocks.
As of Public Beta 23, Mithril ore may be mined with any pickaxe of iron strength or higher. Prior to Public Beta 23, mining Mithril ore required a pickaxe of Mithril strength, but a Dwarven pickaxe or mattock would work as well.
When you look at the picture, you'll notice that it is quite difficult to tell the five ores apart in for example a dark cave. You can recognize Mithril ore by its unique texture, it's slight purple or light blue tinge, and its unique glimmer effect that occurs every few seconds.
- Prior to Public Beta 33 mithril ore could be found in Meneltarma. An in-depth explanation as to why it was removed can be found on that page.
