Moderately large operation for Lead which continued to operate up until the 1950's. Extensive spoil tips can be seen across the valley floor and all the way up the hillside, much of which are disappointingly barren, although excavating into the spoil, particularly higher up the hillside shows indeed the existence of minerals
