Carne (1822) reported a new mineral from this locality, which he named "isopyre". It later turned out to be impure opal.

Greg & Lettsom (1858) and Hall (1868) list several zeolites as occurring at Wheal Carne. As pointed out by Russell, this is most likely a confusion with Wheal Cock Carn, i.e. that part of the cliff between Crowns Rock and Wheal Cock Zawn below which a prehnite-bearing vein crops out.
