Galena is an ore of both lead and silver. It is found as veins in a variety of locations. When galena ore is smelted, it will produce 4 lead bars and 04 silver bars (with a 50% chance of each silver bar being produced). On average, each nugget of galena will produce two bars of silver when smelted.
