1Includes data available through August 2004.
2Estimated data were rounded to no more than three significant digits; may not add to totals shown.
3In addition to the commodities listed, amethyst, aquamarine, bitumen, diamond, emerald, garnet, granite, lime, phosphate rock, ruby,
rolled-steel products, sapphire, soda ash, talc, tourmaline, tungsten, zinc, and zircon are mined, and a variety of crude construction
materials, (stone and sand and gravel) are produced; but information is inadequate to estimate output.
4Reported figure.
5Considerably more barite is produced (about 250,000 metric tons per year) but is considered to be commercially unusable.
