2012年全球金矿探勘预算创新高
关键字：金矿开采
SNL金融经济集团发布报告指出，2012年的金矿探勘预算创下历史新高达到逾60亿美元。不过数据也显示，金矿储量的增加远不能弥补每年被开采出来的数量。
报告显示，1990-1997年期间，全球金矿商的年度探勘预算由9.3亿美元增加1倍以上至22亿美元，期间总共发现了103处大型金矿（黄金资源200万盎司以上），平均的发现成本为9,440万美元；1998-2002年期间发现了31处金矿，平均的发现成本为1,327美元。2003-2012年期间，金矿商的年度探勘预算平均年增为31%，2003-2009年发现的69处大型金矿的平均发现成本为2.025亿美元。SNL MEG指出，确定一处大型金矿通常需要三年的时间。
报告称，依据75%的资源储量转换率，以及90%的开采率计算，1990-2012年期间所发现的金矿的生产潜力为每年5,730万盎司，此仅为同期全球金矿年产量7,630万盎司的75%。而过去15年，全球36个国家总计发现107处的大型金矿，并令全球的黄金产量增加了8.008亿盎司，但此仅为同期12亿盎司金矿产量的56%。
就主要地区来看，过去15年，北美新发现的金矿资源占全球发现总量的23%，平均发现成本为每盎司49美元；拉丁美洲占21%比重，平均发现成本同为49美元；非洲占19%比重，平均发现成本为33美元；欧洲占10%比重，平均发现成本为13美元；澳洲占8%比重，平均发现成本为61美元。
