A metal mine complex with an extensive set of buildings surviving.  The Cornelly, Jones or Townsend's Mine, was worked intermittently for lead in 1845, 1866 to 1874 and 1884. Considerable quantities of ore were extracted, averaging 35ozs of Silver per ton of Lead, but these were insufficient to cover working costs.


Uniquely, its engine house, which has been consolidated, lacked a lintel in order to better accommodate the beam of its original engine.  The main structures enclosed by the protective fence also include a chimney, boiler bases, an office block with the pay window downstairs and a heated drawing office upstairs, a winding house and a small ore store. The last probably dates from an early period, as also the long running bundle, with an angled dividing wall, just to the north-east of the enclosure. There are traces of a circular buddle nearby and a substantial adit was exposed when storm water burst forth from the deads (spoil heap). 


A simple powder house, fenced shafts and (private) remains of a sub-rectangular dam may be found in the boggy rough ground across the track to the south. The quantity of granite incorporated in the buildings is testimony to the nature of the rock that the workings had penetrated. It is said that there was a belief among the miners that the granite was more productive than the slate which may explain the repeated reopenings of this mine.
