Mists of Pandaria - patch 5.0.1
Manticite Ore was introduced in the World of Warcraft expansion: Mists of Pandaria. It will spawn in the mid level zones to high end zones where you may find yourself leveling from 87-90. Maps and routes are not yet available for Manticite Ore, but as the expansion gets closer to release there will be a Manticite Ore Mining Guide made available to you on a map below.
You will need a mining skill of at least 550 to be able to mine Manticite Ore. It is comparable to what Elementium Ore was in Cataclysm or Saronite Ore in Wrath of the Lich King. It is the mid level ore to Mists of Pandaria.
