Nether Metals is a mod responsible for modifying the generation of mineral resources in the Nether dimension. With this mod installed we can find common Overworld minerals, such as gold, diamond, red stone, lapis lazuli, iron, coal and emerald.

This way, the mineral resources most used in the game will no longer be owned by the Overworld, and will now be part of the Nether dimension. Also, if we add other mods such as Base Metals, all their mineral resources will also be added to the Nether dimension.
