It would be great to have a possibility to whitelist or blacklist biomes (or best to have both), in which we want/don't want to see ores from this mod.

E.g. I would like to (but likely not only me) whitelist only mountain biomes, to make the ores and gems from this mod in pair with the vanilla Minecraft emeralds.

If Forge doesn't provide APIs needed to achieve this and you would need to do something hacky (I don't like such solutions unless they are really necessary), please let me know and feel free to close this feature request.

I'm reopening this since it still applies to this repository.
