The remains of the workings can still be seen as shafts and mounds to the south of the Hendre Valley and the A541 Road. The largest shafts are located in the Garreg-Boeth Woods and Big Wood at SJ 1865 6760, extending eastward to SJ 1915 6755.

Historically, the Garreg-Boeth Vein was further developed by the South Halkyn and Rhydymwyn Mining Company when the Halkyn Deep Level Tunnel reached the sett in 1908.
