When galena ore is smelted, it will produce 4 lead bars and 0-4 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. Galena can also be used in alloy reactions requiring silver-bearing ore. Because these reactions treat the galena nugget as the ...

Galena can also be used in alloy reactions requiring silver-bearing ore. Because these reactions treat the galena nugget as the equivalent of 4 silver bars, the resulting alloy will show a roughly 30% increase in value over smelting the galena separately.
