For over 40 years the U.S. Bureau of Mines has issued an annual summary of mining activity in Burma which is now available on-line. These useful reports include information about surveying, mapping, exploration, concession grants, mineral exports and imports and the operations of major mining companies, as well as a valuable five year tonnage table for all major mineral products. The reports cover a wide range of mine products including base metals, precious metals, non-metallic minerals and petroleum. Cement and steel products are also covered. The focus of these reports is on large-scale mining operations and they tend to leave out of consideration the activities of smaller national companies and the mining ?rushes? that occur from time to time, attracting the participation of thousands from around the country. There is little emphasis on the environmental concerns associated with mining activities in Burma. Burmese government reports provide the major sources for the information provided in these reports, but, particularly in recent years, they have also included information from the section on Burma (Myanmar) in the Mining Annual Review produced by the Journal of Mining. The reports are usually a year out-of-date by the time are made available on-line. According to the Department of Geological Survey and Mineral Exploration (DGSME) under the Ministry of Mines, the output share of the mining sector by the state-owned mining enterprises decreased to 5.5% in 2001 from 11.6% in 1998, and the output share by the privately owned companies increased to 93.4% in 2001 from 85.8% in 1998. In 2001, only one gold mine (the Kyaukpahtoe), three nonferrous metals mines (the Bawdwin, the Bawsaing, and the Yadanatheingi), and two coal mines (the Kalewa and the Namma) were still operated by the state-owned mining enterprises; and only one foreign mining company had committed to invest $6.12 million in 2001 compared with $18.5 million committed by three foreign mining companies in 2000. Of the four active foreign exploration companies in 2000, only two were active in 2001. As a result of decreased exploration and development, export earnings from the mining sector dropped in 2001.
