Abstract

In the late eighteenth century New Zealand was a world leader in the application of electricity to mining, the introduction of the cyanide process of gold extraction and the adaptation of the bucket ladder dredge to the extraction of gold from alluvial deposits. This paper discusses the history and features of the New Zealand style dredge and its influence on later American designs. Advances in gold dredge design are illustrated by the Kohinoor dredge, Redman's Creek and Rimu dredge. Both operated on the West Coast, South Island, New Zealand. Although New Zealand's progress was eventually supported by the agricultural and pastoral industries the gold mining industry of which dredging was an integral part provided markets for the fledgling farming industry, generated overseas capital, encouraged investment and attracted the man power necessary for growth.
