The Old Gunnislake Mine Gunnislake, Callington District Cornwall, England

摘要

The Old Gunnislake mine is well known among collectors of Cornish minerals as the source of classic old specimens of metatorbernite, most of them found around 1811-1812. The mine finally closed in 1872, and surface areas where mining took place have been reclaimed. Some of the underground workings are still accessible, but are quite radioactive.
