“义”湖南平江探义矿获突破 一金矿区远景储量超千吨

  中新社长沙11月21日电 (向一鹏 苏媛)湖南省地质院21日宣布,湖南平江县万古金矿田探矿获重大突破,地下2000米以上深度地层发现超40条金矿脉,金品位最高达138克/吨,探矿核心区累计探获黄金资源量300.2吨。据专家预测,地下3000米以上远景黄金储量超1000吨,以现行金价计算资源价值达6000亿元(人民币,下同)。

  据了解,平江县万古金矿位于江南古陆成矿带,也被称为湖南“金腰带”,带内强烈、多期次的构造岩浆活动为金成矿提供了优异条件,在湘东北地区形成了以黄金洞、万古为代表的一批大型、超大型金矿床,是国内最重要的金成矿带之一。

  湖南省地质院副院长刘拥军介绍,多年来,湖南省自然资源厅、湖南省地质院和湖南省矿产资源集团支持湖南省地质灾害调查监测所在万古金矿田深部、边部找矿,在国内首次运用“勘查区找矿预测方法体系”等创新找矿理论,使用三维地质建模、可控源音频大地电磁探测等高新技术,累计完成钻探15万多米,取得新的重大找矿成果。

  刘拥军说,在万古金矿田地下1500米以内勘探,钻探55孔,就有48个孔发现金矿,见矿率高达87.3%。按照相关产业投资主体计划,将在万古金矿矿区建设安全、绿色、规模化的黄金采矿、选矿、金属冶炼产业链,年产黄金将达到5吨以上,年产值将超35亿元。

  中国工程院院士毛景文和中国工程院院士唐菊兴等专家实地考察后认为,万古金矿田找矿实现重大突破,对实现国家新一轮找矿突破战略行动金矿增储目标任务的实现具有重要意义。

  目前,湖南省地质灾害调查监测所正全力攻关万古矿区整合一体化勘查项目,该项目拟完成万古核心区1500米以浅的金矿详查工作,初步估算至2025年底可新增金资源储量55吨。预计“十四五”期间,万古矿区新增金资源储量将超过110吨。(完)
