OAN field survey, located by GPS to an accuracy of +/- 1m. Building remains on the south side of mountain road. The site consists of a low earthfast stone wall that runs for 10m with the north eastern wall return surviving. Other building divisions can be seen running upslope to the south. At the roadside appears to be a building of three bays. To the south is another possible four bay building and to the west there is a large upcast spoil heap and disused shaft The site is probably related to the extensive quarrying and mining processes of Minera. 2002/10/16/OAN/NW
