Nether Ores is a mod that adds various world generating ores to the Nether only. These ores need to be smelted before they can be used in any way and they typically yield two times of their respective ores and their products. Mining these ores has a good chance of angering nearby Zombie Pigmen. Additionally, mining nether ore adjacent to another nether ore can cause them to explode, which can even cause a chain reaction.
