Buller Gorge Goldmining History
 
 
 
 
Sluice and Stack
 
 
 
 

With a supply of high pressure water, miners were able to employ their favourite method of working - hydraulic sluicing. powerful jets of water were played onto terraces, cutting them down and washing them away. Large rocks were rolled aside and neatly stacked while gold-bearing gravels passed into timber sluice boxes. Gold was trapped by wooden bars. Lighter stones carried on down a deeper channel called the tail race to the river.

When the process was completed, nozzles and undamaged pipes were taken to other claims, unsound pipes were left to rust and original native plant species gradually regenerated.
