Botallack Mine (Cornish: Bostalek) is located near the village of Botallack near St. Just, Cornwall. The mine site is now in the care of the National Trust. Part of the site appeared in both the 1970s and 2015 drama series of Poldark. In the recent series much of Botallack appeared as Grambla Mine. It is located close to Wheal Owles which featured as Wheal Leisure in the same series.
