2007年,受贱金属和铁金属连续走高及贵金属价格飙升的驱动,全球矿产勘查总体活跃。对能源长期供应的关注,导致铀勘查高潮迭起。据金属经济小组对2007年矿产勘查支出的估计,用于非铁金属勘查(包括铀)的支出总计114亿美元。 Driven by the continuous rise in base metals and ferrous metals and soaring precious metal prices, global mineral exploration was generally active in 2007. Concern over the long-term energy supply has led to the climax of uranium exploration. According to the Metals Economic Panel’s estimate of mineral exploration expenditures in 2007, spending on non-ferrous metal exploration, including uranium, totaled $ 11.4 billion.
