Copper Nuggets, mined from Native Copper, is one of the three ores that can be smelted directly into copper, and can also be combined with other ores to create five different alloys. Native Copper is found as veins in sandstone and in all igneous extrusive layers.

• Copper bars
• Brass - with sphalerite
• Bronze bars - with cassiterite
• Trifle pewter - with 2 cassiterite
• Fine pewter - with 3 cassiterite
• Billon - with silver nuggets, horn silver, galena, or tetrahedrite
