Copper Ore

Copper Ore is an early game ore, which spawns on the surface as well as in the Underground and Cavern biomes. It is the weakest and most easily obtained tier of ore in the game. Its primary use is to make Copper Bars, which can be used to create the Copper tier of equipment. The equivalent of Copper Ore is Tin Ore, which will sometimes replace Copper in a world. Copper Ore has a small chance to appear as a bonus drop from Slimes.

New characters will always start with copper tools, no matter what ores the world spawns.

Tips

 * New players may want to avoid wasting effort trying to mine copper ore as wood/cactus armor and tools easily outweigh the usefulness of this ore. However, it is used in some decorative recipes.
 * The Copper Shortsword that you start with is made of Copper Bars, which can be crafted from Copper ore. It's not a good idea making a shortsword out of copper unless you lost it.
