Immediately west of the entrance to Furness (Horseshoe) Quarry, close to the road but hidden in vegetation. Worked for fluorspar in the late 1970s/early 1980s. Entrance collapsed in mid-1990s.
No known access restrictions. Obvious parking spots close to base of crags and in lay-bys in the dale and next to electricity sub-station at foot of Eyam Dale. DO NOT BLOCK the sub-station entrance. Take care, as area is notorious for thefts from parked vehicles.
Parts of the mine are in an unstable condition.
