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. |
