A single level enters the hillside behind ‘Green Acres,’ with a small spoil heap outside. The sleeper impressions of a former tramway can still be seen on the floor of the level. The mineworkings extend across the southern and western slopes of Roundton Hill, including a level with a former tramway and a spoil tip containing a probable building platform. Other features include a substantial open cut, an adit, and shallow surface trial workings. Much of the site consists of dispersed workings, some of which may have been no more than exploratory trials.

Early mining activity, possibly for lead, dates back to 1772 (Britnell, Martin & Hankinson, 2000) and is likely associated with the level shown on Ordnance Survey maps from 1882. By the later 19th century, the site was primarily worked for barytes. Mining was fairly extensive but remained small-scale, with many of the workings likely being exploratory trials.
