Unitary authority : Powys
NGR : SN8525082100
Site Type (preferred type first) : POST MEDIEVAL LEAD MINE

Summary :
Lead mine (Pre 1845-1871). By 1861 there was a deep adit and 2 levels. In 1864 a shaft was cut near the present A44 road. The remains of these workings are badly preserved with the shaft being infilled as well as the levels on higher ground above the road. Buildings included a horizontal 14" steam engine house for pumping and drawing at the 1864 shaft together with an adjacent 25ft boiler housing. The dressing floors were powered by a 20ftx6ft waterwheel & 2 smaller wheels. The foundations of these structures have been almost totally destroyed. A crusher house base and washing/picking/jigging platforms were present along with traces of round buddles. All of these features have been extensively damaged by removal of the structural fabric for hardcore in farm roads and for infilling mine workings.
