 Record Description THese shafts are located on 'feebly mineralised (with galena and brown carbonate) but persistent fracture crossing below Blea Barf on Crackpot Moor ... this work was being done by J. Davies in 1818-23 when some 65 pieces (about five tonnes) of lead was produced.... production of a similar order continued as late as 1850.' Reference:Dunham K.C. and Wilson A.A., 1985. BGS Memoir: Geology of the North Pennine Orefield. Vol 2 Stainmore to Craven, pp169-170 and Figure 31.
 Dimensions See photgraphs
 Additional Notes This mine is of great interest in the high, at 470m elevation, and lonely situation of the strings of shafts together with the levels on the slopes below Blea Barf on the southern edge of Swaledale. The green turf covered limestone of the shaft mounds contrast greatly with the dark brown heather covered sandstone of Blea Barf Summit at 540m, see photographs.
