Wheal Carpenter, Fraddam, Gwinear, St Erth - Gwithian Area, Cornwall, England, UK

A small mine which has a recorded history starting in 1792-1798. The next recorded working was from the early 1800's to 1818. And again from 1850 to 1855. The mine is known to have produced copper, tin and silver ores. But the only recorded output is 1230 tons of copper ore. The silver ore was in the form of capillary native silver. Engine (Red) lode (east-west) is intersected by a cross-course lode (north-south), this is where the silver may have come from. Silver mineralisation associated with the north-south cross-course faulting, is not unknown in Cornwall.

The site was largely destroyed about 20-30 years ago.

Data for period 1854-1855 from "Cornish Mines, University of Exeter (1987)"

Specimens of adamite in the Natural History Museum, London supposedly collected here 1953-55 by Arthur Kinsbury (1906-68) are now considered "implausable" and probably from Lavrion. This is one of a number of likely or definitely falsified Kingsbury localities.
