Mine mainly worked the Black Ashgill Cross Vein with extensions that reached
the Caplecleugh High Level in the northwest and the Woodmere Well Vein in the
southeast of the mine. The mine did actually connect with Caplecleugh (27m
below) via the Middle Steed Sump. A level was also driven southeast under
Perry's Dam, but there are no details on which vein this was. Looking at dates
on plans, level driving had terminated by 1820 - 1824. The cross vein was
worked around 250m in the Great Limestone. Ore was raised in 1792 by James
Johnson and Company and in 1813 the mine was leased to the London Lead Company.
There are approximately 1.5km of passages.
The mine is on private land.
