Located 24 kilometres south south-east of the Ashburton Downs Homestead, and about 10 kilometres north of the Ashburton River, as a bulldozed area across the western end of an east-west trending ridge. It is remote and not easily reached by a long diabolical track from the south-east. The source co-ordinates appear to be incorrect.
Mined in 1951, 1961 and 1963, producing 20.37 tonnes of copper ore, and 115.36 tonnes of cupreous ore grading at 17.73% Cu.
Limonite-quartz veins and pods up to 50 metres thick, and a few metres long, with malachite, chrysocolla, and rarer chalcocite and cuprite, in slate dipping 5-10 degrees north. The source states the deposit is capped by an exotic cuprite gossan but provides no further details. Assuming this still exists (no guarantee) it would make for an interesting study considering other locations in the region like Bali Lo.
