The World's First Undersea Mine Is Opening Off The Coast Of Papua New Guinea

Located about 50 kilometers (31 miles) north of New Britain's port city of Rabaul, Solwara 1 is a deposit of what is known as "sea-floor massive sulphides" -- rocks containing high grades of copper, gold, zinc and silver.
