Where to Farm Obsidium Ore
This guide is updated for patch 4.3.
Obsidium is one of three ores (the other two being Pyrite and Elementium) that were introduced with Cataclysm. It is the lowest level of the three ores and you can begin farming it at about level 78 with a Mining skill level of 425. Obsidium will be a popular ore to farm in Cataclysm because there will be a demand for it at the higher end profession levels. It will not, however, be as valuable as Elementium or Pyrite because those ores will be harder to obtain.
Where to Mine Obsidium in Mount Hyjal
Mount Hyjal: Levels 78-82
I’ve chosen Mount Hyjal as a good farming spot for Obsidium because the other zones that contain it have a lot of underwater mining involved. The circuit on the map is easy to follow and there aren’t really any special instructions that you need to know about.
