Survey undertaken in May 1997 of extensive area of tinworking in the lower Walkham valley. Masonry remains had been assumed to be connected with 19th century copper mining. However a spread of dark red tin slimes suggests that this was the site of a tin dressing floor. As there are no buddles the floor may date to pre 1850. Other buildings and a flue form part of the complex and may have ben used for roasting/burning tin ore to remove arsenical and other impurities.

Building complex comprising an enclosure with a six-room building at the east end. Two possible chutes emerge from openings in rear wall of building. An open-fronted chamber with arched roof has a flue which can be traced up hill to the square base of a presumed stack. The east end of complex has a long retaining wall with a levelled terrace. The discoloration of tin slimes suggesting tin dressing.
