Copper Ore is a type of Ore that is primarily obtained from Mining. It can be used to make Bronze Bars with a Furnace, consuming 1 Oil. Since Bronze Bars sell to the NPC Shop for 5 Coins, smelting Bronze Bars is a common way to obtain coins, especially at early levels. Copper Ore will yield 1 Mining XP per ore with a Pickaxe, making it the most efficient Ore to level Mining.
