On March 28th, Shandong Gold Group held a press conference and found that a world-class giant single gold deposit was discovered, and it is expected to submit more than 550 tons of gold resources. This is expected to become the largest gold mine in the history of China, and it is located in Laizhou, the northwest of Jiaozhou, an important gold mine concentration area in China. Laizhou-Zhaoyuan area in the northwest of Jiaozhou is one of the most important gold mining areas in China. It is also a national-level self-contained exploration area. Gold reserves and gold production rank first in the country, and it is one of the few extra large gold mines in the world. Gathering area. As early as the Tang Dynasty, there was a gold mining history in the Jiaodong area, which has a unique gold-rich integration mine condition. Laizhou City, which belongs to the land, has deep roots with gold. History of prospecting in Laizhou area Since 1949 Wang Xianzhi, Yan Kunyuan, Yuan Huizhuo and others investigated the Jiaodong gold mine and estimated that the Sanshandao gold deposit has a reserve of about 10 tons. 1957 The State Council proposed to vigorously restore and develop gold production, and Jiaodong began the geological work of the system. After 1965 The 87th team of the Shandong Provincial Bureau of Geology and Minerals (the predecessor of the Sixth Geological Team), on the basis of the work of the predecessors, broke through the constraints and continued to explore, and successively discovered a series of fractured altered rock type gold deposits such as Sanshan Island and Jiaojia. . After 1975 The geological work situation of gold mines in Shandong Province has changed. In the Jiaodong gold mine concentration area, in addition to the province's geological, metallurgical, local geological teams, there are many other geological survey departments, armed police gold units and other units infiltrated into Jiaodong. 1985 The "Jiaojia-style new type of gold mine discovery and its outstanding prospecting effect" completed by the relevant personnel of the Sixth Geological Team of Shandong Province won the National Science and Technology Progress Special Award. 2007 After two and a half years of exploration, the Shandong Geological Sixth Team discovered a large gold mine in the deep part of the famous Jiaojia Gold Mine metallogenic belt, the deep gold mine of Laizhou Temple, with a proven reserves of 51.83 tons and a potential economic value of nearly 8 billion yuan. Year 2008 The Shandong Geological Sixth Team discovered a large-scale gold mine in the deep metallogenic belt of Jiaojia Gold Mine in Jiaodong. The proven gold mine has a crude oil resource of 105 tons and a potential economic value of more than 20 billion yuan. After 2011 Shandong Province has defined the “358†target for geological prospecting, established a strategic plan office and technical support organization for mine exploration, coordinated geotechnical exploration, gold, metallurgy, coal, chemical, building materials, nuclear industry, armed police and other geological exploration units and mining enterprises. . Shandong Province has made significant progress in prospecting and formed a number of new resource exploration and development bases. Laizhou City's prospecting results have attracted particular attention. Chen Xiaochuan, academician of the Chinese Academy of Engineering, evaluates the gold resources in Jiaodong In an exclusive interview with reporters, Chen Yuchuan said that China has great potential for gold resources. The Ministry of Land and Resources has conducted an evaluation of resource prospects in the past few years and has been engaged in eight years. They concluded that the total amount of gold resources in China is about 32,000 tons, mainly concentrated in the shallow 2000 meters underground. About 500 meters is about 18,000 tons, and 1000 meters is about 25,000 tons. In the past, our mineral exploration was generally shallow at 500 meters, and the prospects for prospecting outside the existing mines were still very large. For example, some time ago, the mines in the crisis mines were looking for mines. Basically, more than 80% of the projects were mines, and the results were very good. The most typical is the Jiaodong area. Chen Yuchuan said: "The Jiaodong area is one of the few super-large gold mines in the world. It is comparable to the ultra-large metallogenic belts in South Africa and Uzbekistan." The Jiaodong area now has mines with reserves of more than 1,000 tons. For example, the gold resource reserves around the Jiaojia Gold Mine have exceeded 1,000 tons, and the Sanshan Island Gold Mine extends northward to the sea, and the gold resources are also abundant. In addition, Shandong Gold Group has drilled a 4,000-meter deep well in the Jiaodong area, with mines below 2,600 meters, and the grade is high, and the prospects are good. The same is true in other regions. Twenty years ago, Chen Yuchuan went to the Beibei gold mine in Yunnan. At that time, the mine was very small. Now, through continuous exploration, it has been found that the reserves of gold resources are more than 300 tons. This is completely a new mine, the Qinghai-Tibet Plateau. The same is true for gold mines. "I think the reserves of gold resources in the Qinghai-Tibet Plateau are also very large," Chen said. Chen Qichuan said that overall, there is no problem with the reserves of gold resources, and the prospects are very good. The key is to carry out the prospecting.
