Clwyd Metal Mines Survey

Penygelli

Geology
Carboniferous Limestone.

Workings
The Pen-y-gelli Mining Company worked the western end of the Milwr Vein for a span of twenty years within the area of Pen-y-gelli Wood, and to the north of the A5026. At least six large shaft mounds lie on farmland to the south of Pen-y-gelli Farm and to the immediate east of the woods. Shafts are within the woodland to the north of a large Quarry, Chwarel Pen-y-gelli, the most obvious being at SJ13487635, SJ13497637, SJ13557640 and SJ13587651. The dense vegetation (July 1993) prevented a thorough survey of the woodland area. On the 1st edition OS Flintshire Sheet V.11, shafts are located to the south of the new A55. Only two shaft mounds are now visible at SJ13755570 and SJ13705565. The area on the 1st edition map was marked as Ffrith y Garreg Wen Training Ground, possibly these workings were related to Pen-y-gelli.
