The opening to the shaft is 6 by 4 metres (20 ft × 13 ft) wide and is filled with water to approximately 1.5 metres (4 ft 11 in) from the surface. Within the fence there are the remains of one of the mine's head frame leg footings, and outside the fence on the eastern side are some small mullock heaps.
