Copper Ore

Copper ore is a mineral block found underground.

Natural generation
Copper ore can be generated anywhere in the Overworld between from Y=10 to Y=138 in veins of maximal size of 16.

Breaking
Copper ore must be mined with a pickaxe, or else it drops nothing.

Breaking copper ore drops the ore itself. The ore has to be smelted using the Forge in order to make Copper Ingots that can be used to craft items.
