The site of a post-medieval lead mine. It is shown on the valley floor of a tributary stream of the Sulby River on the 1870 1:2500 scale Ordnance Survey map. Recorded by geologist G.W. Lamplugh as a trial made about 1866 in the ravine of the western feeder of the Sulby River under Sharragh Bedn, 600 yards north of Croit, where a line of disturbance and faulting traverses the slates. Some lumps of lead ore are said to have been obtained, with one level driven about 50 fathoms, but Warington Smyth's 1866 assessment found it "a level driven and shaft sinking with nothing to recommend it." The lode contained quartz, lead, baryta and oxide of iron, but only in moderate quantities.
