Obsidian Ochre, the most valuable member of the Dark Ochre family, was only first discovered a decade ago. The sleek black surface of this mineral managed to reflect scanning waves, making Obsidian Ochre asteroids almost invisible. Advances in scanning technology revealed these beauties at last.

Dark Ochre was for years ignored as a worthwile ore to mine until improved refining techniques managed to extract the huge amount of nocxium inside it, the highest ratio of nocxium found in any ore in the world. 400 ore units of Dark Ochre are needed to refine it.
