Why is this place significant?
Historic Significance
Historical Significance or Value These tanks are a spectacular physical reminder of the leading role played by New Zealand mining engineers in the development at the turn of the century of a new method of gold extraction from low grade ores. It enabled the Coromandel-Thames-Ohinemuri fields to be more fully exploited, and for a time, to figure as some of the highest producing gold mines in the world. The process was widely employed elsewhere in the world.
Physical Significance
ARCHITECTURAL QUALITY: These cylindrical concrete tanks are the only examples of this type of construction and size in New Zealand. TOWNSCAPE/LANDMARK VALUE: These huge concrete cylinders which dominate the site of the former gold workings have a considerable landmark value.

ARCHITECTURAL DESCRIPTION: These six concrete cylinders are the largest cyanide tanks remaining in New Zealand. The cylinders are 16.7 metres (55ft) high and 3.66 metres (12ft) in diameter. Cyanide tanks elsewhere were smaller in size and variously made of wood, iron or steel.
