On Friday the China Minmetals Corporation signed a 15-year contract with the International Seabed Authority (ISA) for exploration of polymetallic nodules on the deep seabed of the Pacific Ocean. The ISA has now executed nearly 30 exploration contracts for polymetallic nodules, polymetallic sulphides, and ferromanganese in the Atlantic, Indian, and Pacific Oceans. These materials are rich in minerals – such as cobalt, lithium, and tellurium – used to produce batteries and solar panels. Last month British scientists announced the discovery of a deposit of tellurium deep in the Atlantic Ocean sufficient to make solar panels capable of generating 65% of the United Kingdom’s electricity supply.
Created under the United Nations Convention on the Law of the Sea of 1982 (UNCLOS), the ISA regulates seabed activities occurring more than 200 miles offshore (i.e., beyond countries’ Exclusive Economic Zones). The mining part of UNCLOS (aka Part XI) was renegotiated in the early 1990s resulting in the 1994 Implementing Agreement. UNCLOS became effective later in 1994 when a 60th country (Guyana) ratified it. Over 160 countries have now ratified UNCLOS, but the United States has not. As a result, U.S. companies cannot pursue ISA contracts.
