In vein cutting grey Ordovician limestone.

"Colourless, light-green and mauve fluorite occurs with white, pink and light brown platy barite in coarsely crystalline white calcite. The colourless fluorite fluoresces yellowish white and the calcite fluoresces bright pink when exposed to ultraviolet rays ('short' rays more effective than 'long').

The deposit was discovered in 1918 by G.M. Wallbridge. It was worked for fluorite from open cuts and two shafts (125 feet and 50 feet deep) first in 1920-22 and later (by Dominion Fluorspar Company Limited) in 1941-43. The Herrington fluorite mine ajoins this mine to the north (150 feet) and the Lee Senior fluorite mine is about 300 yards to the south. There is a large dump near the main shaft which has been fenced off."
