Two separate sets of workings. The easternmost has a gated deep adit joined to adits above on the hillside. Westernmost had a mill near to the Lake which was obliterated by the pumped power scheme. A number of blocked adits dotted up the hillside to a large, deep and dangerous looking open stope.
Total ore is that attributed to both west and east mines.
