Clwyd Metal Mines Survey

Waenlas

Geology
Carboniferous Limestone cut by the Llanferres Fault.

Workings
The Llanferres Fault runs eastwards from the River Alyn. The Waenlas Mine worked the Waenlas Bach Vein on the western end of the Pant Du Vein, the line of which appears as a series of shafts running downhill through the woodland westwards as it falls towards fields of pasture (SJ19756010). Two shaft mounds are located to the west of the woods; SJ19456030, being south of the track to Pentre-Cerrig-Mawr, and SJ19306050, which could have been the horse and pulley shaft that Earp (1958) refers to. Smith (1921) states that the vein comes to the surface at the east end of the mine, but any other evidence has disappeared in the Big Covert Woods. Documentary evidence refers to Shone's Shaft and a whim. A drainage level was driven from the River Alyn and the mine seems to have been totally worked out to the adit level by 1868. The proposed Llanarmon District Mines Drainage Scheme (LDMD Co Ltd) was granted an Act of Parliament in 1892 to unwater mines in the Llanferres district, but it never reached fruition.
