Alluvial gold.
Verter Burn is the present name. Post Office Creek is the name when the site was active late 19th century, and early 20th Century. Located at the eastern end of Lake Mahinerangi.
The sites were worked by European alluvial diggers ground sluicing, then Chinese diggers re-worked the claims, hydro sluicing, and finally dredging. The auriferous gravels are up to 150 feet thick along areas covering 6 miles of the valley. Some of the gravels are found away from the stream, as a deep lead, caused as an ancient stream channel within a schist gorge. Tunnelling occurred into some of the spurs onto this lead. When inspected in 1918, only four sluicing claims remained active. The gold was very fine, but coarser at the base of the deep lead.
