Workings remain as shafts and mounds in the woodland to the south of the Hendre Valley and the A541 Road. Large shafts are present in the Garreg-Boeth Woods and Big Wood at SJ 1865 6760, continuing eastward to SJ 1915 6755 along the Garreg-Boeth vein.

The Tyddyn-y-barcud Vein ran east to west across these setts, while the North Hendre Vein cut north to south. According to Smith (1921), seven shafts along the Tyddyn-y-barcud Vein were identified as Robert’s, Pritchard’s, Eyton’s, Willianson’s, Marquis, Tyddyn-y-barcud, and Ddol, all of which can still be traced through the woodland.
