G'day,
Dagnabbit Long Reach Excavator Dredge for Placer Gold Mining in Nome Alaska
This video shows Blue Water Mining's "Dagnabbit" long reach excavator dredge. When this dredge enters service in June of 2014 it will be the largest floating gold dredge in operation in Nome.

All that is preventing dredges such as this operating in New Zealand auriferous rivers are the insane "environmental" laws which limit the turbidity that can be added above a rivers usual turbidity levels when machinery in operated in the active river bed. Large New Zealand South Island rivers such as the lower Clutha river would be perfect for such dredges. All of the equipment would be easily sourced ... and there would be no need to design special equipment (more than likely to fail) so a dredge could operate within the regulations. Its not as if it would be the first time large machinery was used in the Clutha ... there were dozens of bucket dredges of a massive size in the Clutha around the year 1900, and in the 1990s a floating barge with an large excavator on-board operated below the Clyde dam to deepen a tail-race in the active riverbed so the electric generators could work more effectively (and there were no resulting detrimental environmental impacts).
