(PbS) Galena is the main ore of lead mined in the North Pennines. Very small amounts of silver could be extracted from it - typically in the ounces range from a ton of galena. This was smelted at Bail hills to produce lead used in making pipes, waterproof roofs and musket ball ammunition amongst other uses.
