The stone-lined filled Engine Shaft remains at SJ18666695, now fenced off, believed to be that working the Coed Du cross-course vein. The shaft and engine house lie within a field of many shallow workings. The mine was drained by a day level driven eastwards to a point north of Plas Wilkin (SJ19416695). Shafts are recorded along the Garreg Boeth Vein eastwards from the engine shaft at SJ18626699, SJ18636698, both lying north-west of the engine shaft. Shafts at SJ18866704 and SJ19086706, both remain to the south of Garreg Boeth Farm. Shafts are recorded within Garreg Boeth Wood and Big Wood, together with four shafts within the area of Round Wood. The sett was reached by the Halkyn deep level by 1908.
