First discovered by collectors Lindsay Greenbank and Mike Sutcliffe in an abandoned 19th century limestone quarry during the early 1970's, the Rogerley is to date the only mine operated on a commercial basis solely for specimen recovery in the UK. Operation of the mine was taken over by UK Mining Ventures in 1999.
The principle workings are an adit extending northward along the Greenbank vein at the High Flats horizon of the Great Limestone. Specimens of green fluorite, often associated with galena have been recovered from discontinuous mineralized flats on both the east and west sides of the vein. Some vugs containing opaque purple fluorite have been encountered along the vein. In August 2007 a new series of flats were discovered at the head of the main tunnel, which have yielded some of the best specimens yet found in the mine. Work at the mine continues as of summer 2009.
