Lead Ore is added by the mods Thermal Expansion, Factorization, and GregTech. Lead ore is an ore block that can be smelted into Lead Ingots. It requires at least an Iron pickaxe to mine and can be processed by a macerator making two lead dust or by a pulverizer to produce two pulverized lead as well as a 5% chance of producing extra pulverized silver. The ore is commonly found around layer 25, is a dark blue/grey coloured ore and is fairly common.
Lead ore can often be found together with Silver Ore, so if you're mining for silver your may want to mine any lead you see to ensure there isn't any behind the lead.
