【西德《核化学冶金公司市场报告》1987年8月号第12页报道】美国能源公司正在怀俄明州南部开发绿山(Green Mou-ntain)铀矿。为了确定其矿石储量,至今已花费1000万美元以上。在美国已知的高品位铀矿中,这是最大的一个。它占地77平方公里,计划1989年第4季度投产,到1990年第4季度达到960吨铀的年设计能力。为这个项目筹集资金的工作于1987年底可以完成。其储量为20000吨铀,品位为0.23％。
[West German Nuclear Power & Metallurgical Companies Market Report, August 1987, p. 12] The U.S. energy company is developing the Green Mou-ntain uranium mine in southern Wyoming. In order to determine its ore reserves, more than US$10 million has been spent so far. Among the high-grade uranium known in the United States, this is the largest one. It covers an area of 77 square kilometers and is scheduled to be put into production in the fourth quarter of 1989, reaching the annual design capacity of 960 tons of uranium by the fourth quarter of 1990. The work to raise funds for this project was completed at the end of 1987. Its reserves are 20,000 tons of uranium with a grade of 0.23%.
