Lead/Zinc (Pre 1840s to 1858+)

Geology
Silurian Upper Llandovery formation. A lead/zinc vein strikes NW-SE in a quartz gangue.

Workings
The main level which was abandoned prior to the 1840s is still visible. There are also two shafts with an adit and trials centred on SN75559465.

Transport
There are short lengths of tramway leading onto the spoil tips outside the shafts, levels and on the dressing floors.

Power
The power source was the Nant Y Gog stream which supplied water to the pumping and crusher house waterwhweels.

Processing
A poorly preserved crusher house and round buddles can be seen on site, there are also remains of ore bins and a picking/washing floor. The processing machinery was apparently brought in from Brynfedwen Mine in 1858. The crusher waterwheel was made in Newtown and the large axle still exists in situ.

Other features
No evidence.

Comments
Very small scale 19th century mine, probably only worked for a few years. (CPAT 1987).
