Originally a lead mine operated by the London Lead Company from 1770 to 1880, this mine transitioned to producing barytes in 1884 and continued operations until 1937. Athol G Allen Ltd held the lease from 1939 to 1981, during which they explored the ground for witherite and barytes, with some production.

The provided grid reference is for the main adit, which has since been blocked. The mine worked several veins, including Wensley Vein, Read Vein, Nacky or Old Sun Vein, White Vein, Little White Vein, Cavern Vein, Lunehead No 1 Vein, and Hunters Vein. The workings intersected extensive sections of cave passage, and the dumps from this adit provided the first Northern Pennine occurrence of carbonate-cyanotrichite.
