So I've been thinking about adding a new ore/s to The Nether, because at the moment, with only Venomite, Necromite, Nether Quartz and Ichorite (plus magma, but magma isn't really an ore), mining isn't too exciting. And the Nether  is, after all, a huge cavern, so I think there should be more of a focus on mining there.

What types of ores would you like to see?
