 There was little on the surface to mark the position of these deposits, some deposits were slightly raised above the surface, some showed a small depression, and it was only after mining started that the extent of the deposits became clear.The mine has been closed several times in its history and never became a large production site.The total production of the mine was 7.3 million carats (1460 kg), and the largest gem weighed 139 carats (27.8 g).
