Clwyd Metal Mines Survey
(also known as Fagnallt)
lies in the community of Cilcain in the county of Flintshire. It is located at Ordnance Survey national grid reference SJ18606690.
The mine is recorded in the CPAT Historic Environment Record as number 18135 and this number should be quoted in all correspondence.
The old Garreg Boerth Vein runs east-west through the mine and at its'western end is known as the Mwynbyll Vein. It is crossed by a north-south lode believed to be the Caleb Bell cross course and the Engine shaft itself lies on the Coed Du cross course in
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.
The engine house is built of local stone and survives to a height of approx 8m. Although overgrown with ivy its beam wall and one other wall remain intact. Its architectural features remaining are the partly blocked up brick archway, probably the exit for
pipes to the boiler house, and the visible beam sockets.
It stands at SJ18666695 and is probably an early 19th-century example of a Cornish engine house.
