Former working area of the mine has been cleared and is now occupied by two mobile homes at SJ 1535 7695, opposite the entrance to Waen Farm. Additional shafts and trial workings in the field to the northeast of the crossroads have been lost due to agricultural improvements. To the southeast of the crossroads, modern housing now occupies the sett once worked by the nineteenth-century Plantation Mine. The air shaft for Waen Mine was reportedly located at SJ 1560 7660.

Waen Mines Ltd worked the Merllyn Lode, cutting an east-to-west vein near Waen Pig Farm. The mine also intersected the Gorsedd Day Level, which had been re-opened in 1878 after being cut in from the north near Tre-Eden-Owain.
