- Copper [forestry + IC2 edition] Any mods that are in the pack by default will have this turned off so CofH core can handle it.
- Firestone ore Pump lots of lava out of the nether and you're bound to find some eventually
- Cobalt gravel ore Worldgen of this is disabled by default, but you can turn it on in the config iirc
- Shiny ore See above
- Steel ore Shouldn't be a thing. But anyway you can get nether pig iron ore which is basically the same thing
- Iridium ore You can get nether iridium ore as a rare spawn now. Overworld iridium was super-rare and I *think* it doesn't appear at all any more
- Dimensional Shard ore You'll only find this at low-ish levels in RFTools dimensions. Not even particularly rare
- Nether Platinum ore This was pretty common in Monster but seems to be a lot rarer in Infinity. Pretty sure it still spawns though
- Nether Nikolite ore [this seems to be a remnant from an old FTB Ultimate-pack mod]
