Mining and Minerals: The Philippines has substantial copper, chromite, and gold deposits, and the country also is rich in many other minerals, including coal, cobalt, gypsum, iron, nickel, silver, and sulfur. There are also lesser deposits, not currently being mined, of bauxite, lead, mercury, molybdenum, and zinc. The latest exploration by the Minerals and Geosciences Bureau in 1996 estimated that the Philippines had 7.1 billion tons of metallic mineral reserves and 51 billion tons of nonmetallic mineral reserves. Of the metallic reserves, copper accounted for 4.8 billion tons, and gold accounted for 110,000 tons. Of the nonmetallic mineral reserves, limestone accounted for 29 billion tons and marble for 8.5 billion tons. The U.S. Department of State estimates that the Philippines possesses untapped mineral wealth of US$840 billion.
