Red Vein and Main Vein in Carboniferous Limestone.
Royle's Shaft remains as a grassed mound, at SJ26525158 with a horse whim circle, to the west of the mineral railway in an area of grassed-over spoil heaps.
A line of old workings to the south-west of Royle's Shaft mark the line of the White Vein.
Reid's Shaft, sunk to 750ft was the centre of mining operations on the Red Vein at SJ26535168. It was originally pumped by a waterwheel before the Darlington's water pressure engine was installed. The shaft remains capped to the north of the railway track.
To the west of Royle's, a collapsed shaft remains fenced off and full of rubbish.
The day level ran from the River Clywedog at SJ26605180, being to the north of Reid's Shaft.
The track of the mineral railway runs between the two shafts and is clearly visible as a public footpath.
The stonework remains of Reid's engine house with some mounting bolts in situ remains in undergrowth in an area of considerable mining evidence.
A 14" horizontal winding engine raised ore at both Reid's and Royle's Shafts.
