由于东欧国家的黄金价格不景气和对一些金属倾销以及欧洲和北美的经济萧条,导致了金属价格下跌,从而严重地影响了矿物勘探。据估计,世界范围的勘探费用从1990年到1991年下降了约8%(1.6亿美元)。金属经济学组织通过对年费用高于一百万美元的公司进行调查指出,全世界的年勘探费为18亿美元,其中加拿大4.3亿,美国3.4亿,澳大利亚3.53亿,南非2.45亿,拉丁美洲2.0亿,这些费用额很可能在1992年进一步下 Due to the downturn of the gold price in Eastern European countries and the dumping of some metals and the economic depression in Europe and North America, the price of metals has dropped, seriously affecting mineral exploration. It is estimated that worldwide exploration costs have dropped by about 8% ($ 160 million) from 1990 to 1991. The Metals Economics survey of companies that spend more than a million dollars a year notes that the annual exploration bill for the entire world is 1.8 billion U.S. dollars, including 430 million in Canada, 340 million in the United States, 355 million in Australia, 245 million in South Africa, and Latin America 200 million, these costs are likely to be further down in 1992
