Metallurgy Mod 1.6.4

Metallurgy is a vast enhancement to the basic mining system, adding well over 48+ new metals (based on which submods you use). Our goal is to create a balanced atmosphere for players to explore and enjoy mining. Metallurgy 2 is also modular, configurable, and entirely tailoring for the player’s experience.

You can find the configs in your .minecraft folder under Config/Metallurgy/(Metal Set)
