The Pant-du Vein extends eastward from the River Alyn, cutting through a limestone ridge.

Evidence of mining remains scattered across three distinct areas. The first consists of shafts and spoil heaps descending the northern slopes of the limestone ridge, just south of the road leading to Burley Hill Quarry. A second group of shafts and spoil heaps lies in a field west of Pant-du farm buildings, extending up the southern foothills of the limestone hill. In the western flanks of Big Covert woodland, a stone chimney still stands at SJ 2030 5960, though its outer stonework has deteriorated on the western side. Despite this damage, its flues remain intact, though no other mining structures survive in the immediate vicinity.

Additionally, the whim shaft west of Tir-y-Coed Farm, known as the Truro Whim, is recorded in historical documents but is considered unlikely to have been part of the Pant-du workings.

Mining activity in the area developed over several distinct locations, with shafts and spoil heaps marking the landscape. The Pant-du Company eventually incorporated the earlier workings of the Goodwins’ Mine, which had been in operation prior to this consolidation. The Goodwin’s Shaft is now identifiable as a mound at SJ 2060 5950. The Pant-du Engine Shaft is located to the west of Goodwin’s Shaft.
