The mine worked a north-east south-west striking lode and produced tin and copper. Between 1860 and 1882 it is recorded as having produced 412 tons of black tin and 690 tons of 5.5% copper ore.
Details of the mine found in Dines, page 269.
Within the last few months an old gunnis working has been infilled using material from the old waste dumps, although the infill is now showing settlement at surface.
As a result of this some fresh faces of mine waste have been exposed in the remains of the dumps that are accessible for collecting. Whilst the majority of the material is largely barren development rock waste, some lode material has been discovered.
The most interesting material has proven to be blocks of Quartz/Tourmaline and Arsenopyrite, which upon cleaning have shown to contain Cassiterite. Further detailed examination has also shown the presence of small amounts of Wolframite and currently in one specimen, some crystals of Stolzite (thanks to Peter Trebilcock for assisting in identifying this).
Under SW UV light there is also a suggestion that minor quantities of Scheelite may also be present although this cannot be confirmed at this time.
