Environmental risks associated with submarine tailings discharge in Astrolabe Bay, Madang Province, Papua New Guinea

Abstract

Highlands Pacific Limited is currently seeking finance for the development of a Nickel-Cobalt mine in Madang Province. Papua New Guinea. The mine will be located near the Ramu River, with processing facilities at Basamuk Bay on the Rai Coast. Basainuk Bay is a small embayment of the larger Astrolabe Bay. Highlands Pacific plans to dispose of mill tailings through a submarine outfall into Astrolabe Bay. Oceanographic conditions in Astrolabe Bay make this practise inadvisable if consideration is given to the ecological health of the Madang region.
