Short-term shell-sand dredging, Success Bank, Owen Anchorage

The proposal is to mine 3. 7 million tonnes of shell-sand from a 67ha area of Success Bank over the two year period 1994 - 96.

The proposed mining area is along the western side of the developing "second" shipping channel where high grade shell-sand deposits have been defined. The mining will be carried out by a suction dredge and will result in cutting into the bank at the northern end. The seafloor, currently at 3m to 5m depth, will be taken down to approximately 15m depth.
