Bryngwiog Mine ; Nantygo Mine

Primary Reference Number (PRN) : 103375
Trust : Clwyd Powys
Community : Halkyn
Unitary authority : Flintshire
NGR : SJ19346923
Site Type (preferred type first) : POST MEDIEVAL SILVER MINE / POST MEDIEVAL LEAD MINE / POST MEDIEVAL ZINC MINE

Description :
Lead/Silver/Zinc (Early 19th century-1907)

Geology
The mine lies on the east-west Bryngwiog Vein, which lies to the west of the Nant Figallt Fault in an area where Cefn-y-fedw Sandstone and Lower Coal Measures meet with the Carboniferous Limestone.

Workings
Evidence of workings survive in the form of one large shaft (SJ19196915), serving as a rubbish dump, in an area of mine waste and household rubbish. A second shaft lies to the west of this at SJ18926925. These could be the two engine shafts (Smith 1921), although there is no structural evidence.

The 20th century Bryngwiog Mines Company sett covered 265 acres to the south of Moel-y-crio, incorporating much of the Plas Winter sett, the Bryngwiog Vein and the Bryngoch, Wern, Fron and Pantygo lodes.

Transport
No evidence.

Power
A reference from an 1870 Mining Journal mentions a 30" pumping engine.

Processing
1870 Mining Journal lists a 24" crushing and winding engine.

Other features
A modernised stone cottage, Bella-vista (SJ19166915) lies between the two shafts, retained by a substantial stone wall and could be mine related.
