Wynnstay Mine

Primary Reference Number (PRN) : 18230
Trust : Clwyd Powys
Community : Penycae
Unitary authority : Wrexham
NGR : SJ24704940
Site Type (preferred type first) : POST MEDIEVAL LEAD MINE

Lead (19th century)

Workings
The sett worked the Wynnstay and Caunter Veins to the south-east of Aber Sychnant. The Wynnstay Vein can be traced by a line of shafts running from the shaft at SJ23954980, being to the north of the road coming up from Minera and west of Gwter Siani Leat, as mapped at SJ24604990, where it crosses the road, in a south eastwards direction towards Youde's Shaft (SJ25454900) and the shafts along the Gomerian Level.

Two open shafts are located at SJ24684945; the north-eastern one having an upper stone lining.

To the south-east of the shafts, the remains of a stone shelter, approx 6m x 4m across stands at SJ24704945.

A group of two shafts and a trial shaft lie to the north-west of the above group.

At SJ24504955, an open shaft has boards over it and recent caving club access facillitated by the new ladders and scaffolding in the shaft. The spoil heap has been reformed.

The vein traverses the road to the south-west of Gwter Siani and the shaft at SJ23924980 is probably on the Wynnstay sett.

To the south-east of the Wynnstay Shaft, Youde's shaft lies at SJ25454900, almost on the interception of the Wynnstay and Youdes' Vein.

The Gomerian Level drained some of the Esclusham Mines and the Caunter Vein supposedly intercepted it (Smith 1921).

Documentary evidence refers to trials at Nant-y-cwm Mawr being in the area of SJ24404970, which would be on the Wynnstay Vein, but according to Brenton Symons map, the Nant-y-Cwm Mawr Vein runs north of the Wynnstay Vein.
