1968年以来,北萨斯喀彻温铀矿勘探一直在不断地扩大,估计1976年的经费开支可能达2千万美元。1968—1976年间,共发现9个互不联系,有经济价值的矿床,成本总计约7千万美元。平均每年发现一个矿床,每个矿床的成本不超过8百万美元。按照这些成功的实例,不言而喻,矿床发现后的勘探原则应该是清楚的,勘探人员应当 Since 1968, exploration for uranium deposits in the North Saskatchewan has been steadily expanding, with estimates of up to $ 20 million in expenditures for 1976. Between 1968 and 1976, a total of nine non-linked, economically valuable deposits were found, costing a total of about 70 million U.S. dollars. On average, one deposit is found each year, and the cost per deposit does not exceed $ 8 million. According to these successful examples, it goes without saying that the principle of exploration after the discovery of the deposit should be clear and that the prospectors should
