An extensive mine complex producing micaceous Hematite for use in rust preventing paint until about 1950. Peak production of about 2500 tons / year was achieved in the 1940's one of the biggest uses being the Navy's battleship grey paint. The last record of mining as late as 1969. The sett comprises 5 east-west lodes worked principally by adits with few shafts. These can be viewed from the public footpath. The workings are barred and reported to be very unsafe. The high quality of the ore gained it the term 'Shining ore' which was adopted by the geological survey.
