Interesting Fact: The Rogerley Mine was developed in the 1970s on a mineralized vein discovered in a disused limestone quarry located near the village of Frosterley by local collectors Lindsay Greenbank and Mick Sutcliffe. The mine was worked for fluorite specimens by the partners on a weekend basis until the mid-1990s, when it was turned over to a group of American collectors who have operated the mine on a seasonal basis since. The mine accesses a series of mineralized flats which have produced a fair amount of green fluorite, much of simply average quality. During the summer of 2007 a new mineralized zone was encountered that has yielded specimens of a much higher quality.
