Specimens of adamite in the Natural History Museum, London supposedly collected here in 1953-55 by Arthur Kingsbury (1906-68) are now considered "implausible" and probably from Lavrion. This is one of a number of likely or definitely falsified Kingsbury localities.
Note on the mineral list: the status of beudantite, carminite, galena, meneghinite, mimetite, and scorodite at this locality has also been changed to "unconfirmed" due to the high probability of fraudulent recording of discovery by A.W.G. Kingsbury.
15 valid minerals.
