Despite grand name, little more than a trial just north of the road.

MINING IN CARDIGANSHIRE. - In the neighbourhood of Aberystwith the mines continue to work with great activity; at the California of Wales, Ponterwyd Silver-Lead Mine, the operations are being carried out with spirit, under or the the management of Capt. J. Paull. The western and middle engine-shafts are both commanded by a splendid water-wheel; the western shaft is sunk between two fine- looking lodes, being the same as the adjoining mine, Cwm Bruno, from which con- siderable returns are now being made, both these lodes will be cut in the 24 fm. level in the course of a few days at Ponterwyd, the result of which is being looked forward to with great interest; these lodes, were seen at surface, produced a good pile of ore in cutting down the shaft. There are also three other large lodes laid open, run- ning through the entire length of the sett, a distance of two miles, containing lead up to the surface, and in places where opened on showing a course of ore 1 ft. wide, solid lead, and within 4 yards from grass: these and other proved lodes form a junction in this property, 30 feet wide, one splendid mass of gossan, carbonate of lime, and lead ore. These lodes are laid down in the Geological Survey, and are to be seen at the Museum in Jermyn-street, proving this junction to be the centre or heart of all the mineral veins in the principality of Wales. Levels are also being driven which will cut all the lodes in the sett, and unwater the mine to a depth of 110 fms. There are about 20 tons of lead at surface, which will shortly be increased, and regular samplings continued. The mine has been inspected by the first agents of the day, who fully confirm the favourable opinion hitherto expressed, that this mine presents more than ordinary prospects of making a lasting and dividend mine….

In 1858, amalgamated with Llywernog and Bog as Llywernog United SIlver-Lead Mining Co. Became part of Clara United between 1861-1863.
