There are two sets of workings exploiting 2 veins. The western workings are exploited by a series of surface stopes with extensive workings underneath. There are a number of routes down to the intermediate shallow adit level (shallow adit open c 2000). One route entered via a short adit leads to a bolted route. A 100’ shaft split in two descends to the deep adit level. Deep adit is blocked by collapse after about 150m. Deep adit entrance can also be entered from near the eastern workings and followed for a short distance to the collapse. The eastern workings is accessed via an adit leading to a stope. Currently blocked passage probably leads to the large stopes which can be entered from above via a surface shaft.
