Overview
Mithril is the rarest naturally occurring ore in Survival 303. It is found on only 5 of the islands in the archipelago, and can be used to create    high-end equipment rivalling that of Bluesteel. It is easily recognized with its signature gleaming purple appearance. Mithril ore requires a Steel Pickaxe or better to mine. It takes about 15 minutes to respawn.

Trivia

 * Refined Mithril used to be transparent and white in color. It was likely changed to purple because the white mithril equipment looked too much like steel equipment.
 * The color of both Mithril Ore and Refined Mithril may be a reference to RuneScape, and in that game Mithril is a gear type that is moderately powerful
 * Mithril as a concept, is first mentioned in The Hobbit by J.R.R Tolkien in 1937, is actually a shiny silver metal with a worth "Ten times that of gold." Also note that "Mithril" is also simply an elvish name, the common tongue referring to it as "Moria-Silver".
