Nautilus PEA outlines the low-cost production potential of Solwara 1

Toronto-based Nautilus Minerals has published a new preliminary economic assessment (PEA) for its Solwara 1 seafloor copper/gold project, located in the Bismarck Sea offshore Papua New Guinea (PNG). The Toronto-based prospective marine miner reported an undiscounted after-tax net cash flow of $179-million and a discounted (15%) net cash flow of $56-million a year. The internal rate of return for the base case is 28%, but it rises to 40% using average forward curve metal prices for copper and gold, the company advised earlier this week.
