This edition of the Minerals Yearbook discusses the performance of the worldwide minerals and materials industry including Burma?s Mineral industry during 1992 and provides background information to assist in interpreting that performance. Volume III, Minerals Yearbook International Review contains the latest available mineral data on more than 175 foreign countries and discusses the importance of minerals to the economies of these nations. Since the 1989 International Review, this volume has been presented as six reports: Mineral Industries of the Middle East, Mineral Industries of Africa, Mineral Industries of Asia and the Pacific, Mineral Industries of Latin America and Canada, Mineral Industries of Europe and Central Eurasia, and Minerals in the World Economy. The total work force of the mining sector was estimated at 83,000 or about 0.5% of Burma?s labor force in 1992. According to the Burmese Ministry of National Planning and Economic Development, the total output of the mining sector, in 1986 constant producers? prices, was valued at $76 million? or 0.89 % of Burma?s gross domestic product (the total value of net output and services), which was valued at $8.5 billion for fiscal year 1992. Of the total output of the mining sector, about 73% was produced by the State-owned enterprises, 26% by the private enterprises, and 1% by cooperatives. In fiscal year 1992, export earnings from jade and gems alone amounted to about $23.5 million and accounted for more than 60% of Burma?s minerals exports. Additionally, a considerable amount of high-quality jade and gems reportedly are smuggled annually to China and Thailand. Exports of copper concentrate in 1992 were estimated at $3.5 million and accounted for 10% of total minerals exports.
