Canada-based, AIM-listed Nautilus Minerals (in which Anglo American is a major shareholder) is in dispute with Papua New Guinea as to the parties’ obligations to complete the agreement reached in March last year for its Solwara 1 copper project. The company, the first to explore the ocean floor for polymetallic seafloor massive sulphide deposits, warned Solwara 1 copper project could be delayed or cancelled because of the dispute with Papua New Guinea over their ownership agreement for the underwater mine.
