Supplied by leat SX56NE/506 which has two sources, the second possibly having been tapped in order to generate enough power to operate the new 8m diameter waterwheel installed here in the early 19th century. Two wheelpits visible. References occur in 1505, 1538, 1600, 1611, 1623, 1639.

(2003) The core part of Keaglesborough Mine, on the lower western slopes of Raddick Hill. The earliest remains probably date from the early 16th century and comprise a series of parallel dumps, representing the remains of an eluvial streamwork. Later openwork mining operations removed the majority of this streamwork. Subsequent mining was carried out underground, with the surface evidence comprising an adit and two shafts. Two tin stamping mills were constructed on the site in the late 18th or early 19th century and both survive as rectangular platforms defined on three sides by a drystone wall revetment. There is a stone-lined wheelpit in the centre of each platform with a tail-race leading from each wheelpit. The water was carried to the wheels via a leat embankment and timber launder. The dressing floor lies to the north, surviving as a series of hollows representing the site of buddles and other devices used to separate the casserite (tin dioxide) from waste materials.
