This mine worked a stockwork consisting of numerous small cracks in a thinly bedded shale that were filled with quartz and cassiterite. The main source of ore however were lenses of almost pure cassiterite, which occurred along the bedding planes.

Although the deposit was small, the extent of the workings was considerable. An adit with two air shafts on its back enters the sett from the west, intersects with Main Shaft at 10 fms below surface and continues another 80 fms to the east. Drives north and south of Main Shaft at adit level connect with two shafts at distances of 125 fms and 85 fms, respectively. Finally, irregular networks of ramifying drives extend within a radius of about 50 fms from Main Shaft at all levels, resulting in "a very complicated mine plan" (Dines, 1956). The ground around the outlying shafts was not further developed, suggesting that they were only sunk to explore the extent of the deposit.

Between 1873 and 1879, the mine produced 586 tons of black tin. Another 24 tons were raised when it was reworked as a part of Trevarran United Mines in 1882-1883.
