“辣条之乡”要变“黄金之乡”?湖南发现千吨级金矿
A massive gold deposit with estimated reserves exceeding 1,000 tonnes has been discovered in central China's Hunan Province, the Geological Bureau of Hunan Province announced on Thursday.
湖南省地质院11月21日宣布,在中国中部湖南省发现了一处储量预测超过1000吨的超大型金矿。
Geologists identified over 40 gold veins, with a reserve of 300 tonnes, within a depth of 2,000 meters beneath the Wangu Goldfield in Pingjiang County, according to the bureau. The total gold reserve at depths reaching 3,000 meters is estimated to surpass 1,000 tonnes, with an estimated value of 600 billion yuan (approximately $83 billion).
据该院监测,在湖南平江县万古金矿田地下2000米以上深度地层发现超40条金矿脉,累计探获黄金资源量300吨。专家会商认为,预测万古金矿田地下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。
The current exploration efforts have been successful largely due to the application of new technologies in conducting exploration at depths above 1,500 meters. According to ore prospecting expert Chen Rulin, the success rate has been exciting – out of 55 drilled holes in regions above 1,500 meters, 48 have revealed the presence of gold, achieving a discovery rate of 87.3 percent. In addition, gold deposits were also found in two drill holes at depths of 2,000 meters, indicating the extraordinary scale of potential reserves.
目前的勘探工作之所以能够取得成功,主要归功于在深度超过1500米的地区应用了新的勘探技术。据探矿专家陈如林介绍,运用新理论、新技术在万古金矿田地下1500米以上勘探,一些区域钻探55孔,就有48个孔发现金矿,见矿率高达87.3%。此外,在两个2000米钻孔也都发现了金矿,这表明潜在的矿藏储量极为可观。
Wu Jun, a director of the Hunan Province Geological Disaster Survey and Monitoring Institute, stated that the Wangu Goldfield is the largest gold deposit discovered in Hunan's history. Nationwide, only around five gold deposits of such scale exist. The exploration efforts have spanned 30 years, during which geological experts have continuously worked on sample collection, drilling, and conducting comprehensive research at the site.
湖南省地质灾害调查监测所地质勘查院长吴俊表示,万古金矿田是湖南历史上发现的最大金矿床。全国范围内,这样的大型金矿床只有大约五个。这项勘探工作已经持续了30年,地质专家们一直在现场进行采样、钻探和全面的研究工作。
While deposits have already been identified at a depth of 2,000 meters, the exploration is ongoing. Wu indicated that based on current predictions, what has been discovered so far represents only a small fraction of this reserve. Upcoming exploration will focus on the fringes and peripheral regions of the field to locate the remaining 700 tonnes of gold resources.
尽管已经在2000米以上深度地层发现了矿藏,但勘探工作仍在继续。吴俊指出,根据现存预测,目前已经发现的资源仅占总储量的一小部分。接下来的勘探将集中在该区域的边缘和外围地区,以寻找剩余的700吨黄金资源。
"Many drilled rock cores showed visible gold," said Chen Rulin, adding that a tonne of ore in the 2,000-meter range contained up to 138 grams of gold.
“许多钻取的岩石芯中都可见到黄金,”陈如林补充表示,“在2000米深度范围内的矿石中,金品位最高达138克/吨。”
Liu Yongjun, deputy head of the Geological Bureau, highlighted that advanced ore prospecting technologies, such as 3D geological modeling, were used at the site. He added that gold was also found during drills conducted in peripheral areas, revealing promising future prospects.
湖南省地质院副院长刘拥军指出,万古金矿田运用了先进找矿技术进行勘探,如三维地质建模等。此外,勘探核心区外围钻孔也发现了金矿,显示勘探前景非常可观。
