The mine developed a section of what may be a continuation of the vein at Frongoch, about 4kms to the WSW. The mine is known to have been worked in the 18th centry. And from 1850 to 1859 the mine was producing some ore, but it was not untill 1870 that a "rich" ore shoot was found. This was cut off by a slide, and was lost.
Recorded output:
348 tons of lead ore

The mine occupies a small north-south valley which the lodes apparently cut on a north-east to south-west strike. The workings are almost exclusively on the eastern hillside. On the south bank of the Mynach river is a wide overgrown fan of what appears to be crushed sands. Above this are a few small tips and the ruins of the building marked as a square below the word 'Aqueduct' on the Ordnance Survey 1887 1:2500 map. The ruin of the magazine is tucked into the hillside nearby. The small side valley is dominated by a large tip associated with a mostly blocked and flooded level. This level would likely have intersected the southerly extension of the open gunnis/shaft northward and further up the hillside. The gunnis extends both north and south, but the southerly extension appears to have a deep open 'shaft' potentially connecting with the level. The northern part of the gunnis is possibly blocked but on the top of the hill is a shaft collar that would be on the strike of the lode. High on the hillside to the south is a further open, flooded level. In the field on the opposite side of the little stream 2 hollows perhaps mark other trials.

The lowest tips contain very little mineralised material. The majority of galena etc is associated with tip by the open gunnis and to a lesser extent the largest tip below. The tip further up the valley below the open level is apparently barren.

Only the gunnis/shaft and the level furthest up the valley are on public access land. Dec, 2020.
