Situated adjacent to the A5 opposite Capel Curig training camp the mine is very easy to find, indeed the somewhat wet to explore main adit is right beside the road, in a sort of 'alcove' set in the retaining wall.
The mine almost certainly first worked by the Romans, later it attracted attention in the 190th century, to finally cease working in 1910. The site has stood idle ever since.
At this time of writing the woodlands are up for sale, so access may not be possible to the site in the future. Below the road is no sign of mining activity, the ground has been completely cleared and turned to agricultural use, however above the road in the woodlands there is more to see.
Entry is through a gate, and following the stream up through the site dangerous partially concealed open shafts are over on the right, the main engine shaft being at the top of the site.
The concrete remains of the winding machinery remain, the shaft itself being covered over in an indeterminate manner, a partially concealed hole at the one corner indicating what lies below. The whole area is overgrown and the vicinity of the engine shaft is of some danger to the unwary, we have no knowledge of what is supporting the cap.
Regardless of this, the mine is interesting to explore, full wet gear being required. The engine shaft passes down through the main stope, this area being false floored which at the time of my exploration was below water.
