So I travelled to the nether today in an attempt to find some of that rare iridium ore that everyone loves. What struck me as odd when I started flying around with my jetpack is that the only ore I could find was pyrite ore, and boy was there a lot of it. I was under the impression that basically every ore available in the overworld would also be in the nether. After noticing this I began to get worried that there were no iridium ores generated in my nether either. Any info on this topic would be appreciated.
