Renowned for its stunning apple-green fluorite, specimens of which grace the collection of the Natural History Museum in London, this mine has been the subject of recent exploration efforts via the main shaft. Unfortunately, these efforts yielded no significant findings. However, numerous straw to light brown fluorite groups were collected, with some displaying excellent quality. These specimens often feature cubes measuring up to 10 centimeters (4 inches) and are frequently partially coated with siderite.
