The Greenlaws Mine is located approximately 1 km south of St. John's Chapel. Two parallel veins, the Greenlaws East and West were worked by the mine, but the east vein appears to have been far more productive. The Greenlaws East Vein was worked by the Beaumont Company between 1850 - 1884 for lead, and for a short period there-after by the Weardale Lead Company. Attempts to reopen the mine in the 1940's for fluorspar were reportedly unsuccessful. Dunham (1990) reports the presence of a small belt of cavity-bearing flats adjacent to the Greenlaws East Vein at the High Flats horizon in the Great Limestone, along with some in the upper portions of the Scar Limestone.

Superb specimens of lemon yellow fluorite from the mine (thought to be from flats in the Scar Limestone in the lower levels of the mine) are held in the collection of the Natural History Museum, London, together with other specimens collected by Arthur Russell, exhibiting a bewildering variety of colour variations.

Since 2010, a group of collectors have been rehabilitating a shaft accessing the mine and are recovering specimens of deep purple, and amber/purple zoned, fluorite. The mine is run as a managed project, with ongoing exploration and scientific research into the genesis of Weardale orebodies. Superb specimens have recently been found, of second and third generation overgrowths of fluorite crystals, overlying large crystal fragments broken from the walls of cavities. The colour variety of these is related to differing pulses of fluids, and ongoing research is aimed at understanding these, and explaining the complex crystal morphology of the overgrowths.
