Drws-y-Coed Mine, Nantlle Vale, Gwynedd (Caernarvonshire), Wales, UK

UK Grid Reference: SH545535
Latitude: 53°3'31"N
Longitude: 4°10'16"W
A very old mine that was reputedly visited by King Edward 1st in 1284. There is a record of Cornish miners working at Drws-y-Coed in 1761 and many miners and "copper ladies" moved here from Parys Mountain in Anglesey during the 1830s as the lodes there became less productive.

Probably at its peak during the period circa 1820-40, the Drws-y-Coed mine remained in production until towards the end of the 19th century. However, by the 1880s output rarely exceeded 200 tons per annum. Attempts to work the mine in the early part of the 20th century were largely unsuccessful.

Although a total output of 13000 tons of ore is recorded, this is thought to be a great underestimate, with the real output possibly about double this figure.
