The 1st edition OS map of 1871 shows four shafts to the south-east of the county boundary and west of Waen Farm (SJ26905390). The 2nd edition map shows old levels on the slopes of the Nant-y-ffrith Woods to the north-east of Gorse (SJ26405370), which appears to be the centre of the mining activity.

To the south of this road shaft mounds can be located in the fields to the west of Waen Farm and to the east and south of Gorse.

The veins are marked on the Brenton Symons Map of 1865, but little evidence remains.
