Comments
Description above is misleading. There is an area of mineworkings on S and W slopes of Roundton Hill. See PRNs 80159, 80147, 80148, 80151, 79612 & 80150 for individual component sites. Early workings may have been for lead - records date back to 1772 (Britnell, Martin & Hankinson 2000), and are likely to have been located on the site of the level shown by OS in 1882. Site was worked during the later 19th Century for barytes. Mine workings were fairly extensive, if small-scale. Much of the workings may have been no more than trials. PRN 80147 is a level with former tramway and a spoil tip with probable building platform cut into it (PRN 80148). Workings also include a substantial open cut (PRN 80151), adit (PRN 79612) and shallow surface trial workings (PRN 80150).(CPAT 2001)
