Wheal Carne is a name relating to a section of what became Geevor mine.

Derived from an early small mine or tin bounds where the name has been incorporated into a later working.

The Wheal Carne workings are located on the south-eastern side of the B3306 road, lying to the east of Wethered's Shaft and to the south-west of Pendeen church. Ironically the name Wheal Carne is commemorated by a terrace of cottages called Wheal Carne Row, pretty much opposite the entrance of Geevor Mine.

Dines makes reference to it in the first paragraph of the entry on Geevor mine. Plate III A is a view across the collapsed collar of Wheal Carne Shaft.

Some early work at Geevor Mine was undertaken through Wheal Carne Shaft.



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


Note:
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.
