Located 2.5 km south-west of Roebourne.
The only information found was across 1906-1907. In August 1907 specimens from the mine were displayed in Perth. Described as chalcuperite it is assumed they contained chalcopyrite and cuprite. Chalcopyrite at least was confirmed by Gibb-Maitland, with minor malachite staining of the rocks. The mine had two shafts to a depth of 40 feet, the lode trending north-east and up to 4 feet wide.
A Mr Clark worked the location. He stated the mine was hampered by a lack of communications and 7000 bags awaited export but no ships could be found. The year before John Truslove and F.L. Duncan applied for the lease (10 acres) but sold a portion of it only 3 months later (to Mr Clark?). 997 tonnes of ore was extracted before 1919, averaging 18.75% Cu.
A cupriferous-limonite vein outcropping sub-vertically in a north-east trending shear. The source states overall mineralisation is weak, however 12 metres under the surface a rich shoot was uncovered, 23 metres long by 1.2 metres wide. It contained chalcopyrite and pyrite passing upwards into cuprite and malachite rich pods. An historic open cut and two shafts are mentioned.
