It came from a gold mine at a reef 1600 metres above sea level. The water wheel powered the stamper battery that crushed the gold-bearing quartz.
The water was essential to power the mining operation. At this elevation summer is very brief with the snow melting sometime in December and freeze-ups well under way again by early April.
After the huge effort of establishing the mine at this altitude and remote location, little work was actually done before the mine was abandoned. The machinery wasn’t installed until 27 May 1882 and it was the following April before the plant was in “working order”. In October 1883 it was reported that the Alpine Reef had been abandoned.
This excellent diagram displayed by the water wheel shows how the plant operated.
I was incredulous at the time and effort that was put into establishing this ill-fated gold venture. The battery had been ordered in Dunedin (January 1880) and was transported from Dunedin to Lawrence by rail, then by ‘trains’ of several bullock wagons at a time into Central Otago and on up the Old Man Range, finally reaching the Alpine Reef in March 1882.
