Nauru Island is rich in phosphate resources, accounting for more than three-fifths of the total export value of the Pacific islands, providing Nauru with a large amount of government revenue.
2. Non-ferrous metals: including nickel, chromium, manganese, copper and other non-ferrous metal minerals, which are also mined and exported in the three Pacific islands.
