(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.

Galena (lead sulphide) or galenite is virtually the only source of lead and an important ore of silver. It is found both in masses and crystallized in cubes, but sometimes in truncated octahedra and has the formulae PbS and a relative hardness of 3. It is a very common metallic mineral, its colour is bluish-grey, like lead, but brighter; its lustre...
