山东发现大型金矿

< class='line1'> < class='richContent richContent0'>

原标题:山东发现国内有史以来最大金矿 潜在价值1500多亿

中国山东网3月28日讯 今年初,在中国产金第一大省——山东省发现一个世界级的巨型单体金矿床,山东黄金集团探获的“三山岛矿区西岭金矿”,目前已备案金金属量382.58吨,预计勘探结束后,可提交金资源量550吨以上,有望成为国内有史以来最大的金矿。

3月28日,山东黄金集团在北京召开三山岛矿区西岭金矿探矿成果发布会,就这一信息向社会进行了公开发布。集团党委书记、董事长陈玉民,总经理、矿业股份公司董事长李国红,副总经理崔仑等出席成果发布会。

胶西北莱州-招远地区是我国最重要的金矿集中区,也是国家级整装勘查区,黄金储量和黄金产量均居全国首位,为世界上少有的特大型金矿富集区。这里金矿密集分布、矿床规模巨大,并以玲珑—焦家式金矿床类型享誉全球,目前已是重要的黄金生产基地。西岭金矿床便孕育于该地区,毗邻三山岛金矿,矿区大地构造位置处于华北板块-胶北断隆-胶北隆起西部,西邻沂沭断裂带,东部为玲珑超单元侵入岩,矿区内深大断裂发育,为金富集成矿提供了得天独厚的条件。

该矿床矿体走向长度超过2000米,单矿体局部厚度67米,目前已探获黄金金属量382.58吨,平均品位4.52克/吨,该成果已于2017年3月8日在山东省国土资源厅备案,正式转入勘探阶段,通过钻孔加密施工,预计两年后可累计提交金资源量550吨以上,潜在经济价值可达1500多亿元,将成为国内有记载以来黄金史上最大的单体金矿床。若按生产规模10000吨/日计算,可连续满负荷生产40年。

“十三五”期间,山东黄金集团提出了“资源为先”的经营理念,西岭矿区作为旗下最为重要的优质资源勘查区,该金矿床的成功发现与评价,不仅充实了山东黄金战略资源储备,而且,与集团多个金矿床处于同一区域,更有利于资源整体开发布局和综合利用,将产生可观的经济和社会效益,为实现十三五发展战略提供了强有力的支撑。更为重要的是,西岭金矿床的发现开创了我国岩金深部探矿的先河,推动了深部成矿理论研究和深部勘查技术的进步,不仅对胶西北金矿集区深部找矿具有重要的现实意义,同时也为我国深部找矿工作研究提供了可资参考和借鉴的范本,将对山东省乃至全国深部金矿地质勘探产生重要的指导作用。
