base metals is a mod responsible for adding new mineral resources to the generation of Minecraft worlds. Some of them are real metals, for example zinc, silver, tin, mercury, nickel, lead and copper. In addition, we can create the following alloys: bronze, steel, brass, invar and electro. Finally, we will also find new invented metals, such as mithrill, diamantine, aquarium, star steel and cold iron.

Most of these new materials will be found in Minecraft Overworld, although we can also find two other minerals in the Nether Dimension and one in the End Dimension. With these new materials we can create many tools, weapons, pieces of armor, decorative blocks and various objects.
