South-west of the Glog mines and on the same lodes. Several shafts and levels between Llethr and the B4343.
Well preserved wheel pit and leat contouring around towards Glog Fawr.
Worked by Probert as Esgair Llethyr in 1785.
About 100 years later, the Taylors drove a crosscut adit to explore the lode for 140fm, and aslo sank a 32fm shaft, driving from the bottom of that.
A more recent level was driven from near the road at a lower altitude.
