Today, the Ministry of Land and Resources held a press conference on the results of deep gold prospecting in Jiaodong area in Beijing. Yu Haifeng, Director of the Geological Prospecting Department of the Ministry of Land and Resources, Gao Ping, Deputy Director of the Department of Science, Technology and International Cooperation, and Li Hu, Director of the Department of Land and Resources of Shandong Province Attending the meeting, the press conference announced to the society the major achievements in the deep prospecting of gold mines in the Jiaodong area, which is also a major achievement of the deep exploration technology innovation strategy to the deep earth. At the same time, Yu Haifeng and others gave detailed answers to questions from the reporters on the spot (questions include: Does deep prospecting have economic value? What is the strategic direction of prospecting exploration under the current geological prospecting industry situation? The potential value of gold in Jiaodong area?)

Since the implementation of the prospecting breakthrough strategy in 2011, the deep exploration of gold mines in the Jiaodong area of ​​Shandong Province has achieved significant results. A batch of large and extra-large gold mines have been discovered. The newly-added gold resource reserves are more than 2,400 tons, exceeding the 61 years since the founding of New China ( From 1949 to 2010), the total amount of resource reserves (1932 tons) found in Jiaodong has made great contributions to the achievement of the 10-year goal of national gold prospecting five years in advance.

The situation is as follows:

1. Major breakthroughs in deep exploration of gold mines in Jiaodong area have world-class influence

The gold deposits in Shandong Province are mainly distributed in the Jiaodong area, with the Sanshandao fault zone, Jiaojia fault zone and Zhaoping fault zone in the northwest of Jiaodong as the main ones, followed by the Qixia-Penglai gold metallogenic belt and Muping-Rushan gold metallogenic belt.

Since 2011, more than 70 large and medium-sized and above gold deposits have been newly discovered in the Jiaodong area, of which large-extra-large gold deposits are all distributed in the "Shandong Laizhou-Zhaoyuan Gold Mine Integral Exploration Area".

Among them, the extra-large gold deposits with reserves exceeding 100 tons include the gold mine in the northern sea area of ​​Sanshan Island, Laizhou City (reserves of 470.47 tons), Laizhou Xiling Gold Mine (reserves of 382.58 tons), Laizhou Shaling Gold Mine (reserves of 309.93 tons), Laizhou Tengjia Gold Mine (reserves of 206 tons), Zhaoyuan City Shuiwangzhuang Gold Mine (reserves of 170.543 tons), Laizhou City Xinli Village Gold Mine (reserves of 141.81 tons).

There are nearly 10 gold deposits with reserves greater than 50 tons and less than 100 tons. Among them, the Taishang mining area in Zhaoyuan City, Shandong Province added 59.4 tons of gold, Linglong Gold Mine added 50 tons of gold, and Sanshandao Gold Mine added 60 tons of gold.

In addition, a large-scale Liaoshang gold deposit was newly discovered in Muping District, Yantai City, with a resource reserve of 69 tons, breaking the previous situation of "only the stars but not the moon" in the eastern part of Jiaodong, and expanding the scope of prospecting in the Jiaodong mining area. The major achievements of deep gold exploration have achieved a historic breakthrough in China’s gold prospecting. Three thousand-ton gold fields represented by Sanshan Island, Jiaojia and Linglong have been formed, making Jiaodong the world’s largest The three major gold mining areas have consolidated its position as the country's largest gold production base. At present, the gold mines in the Jiaodong area have reserves of 3694 tons. In 2016, the mine gold production in the Jiaodong area was 71 tons, accounting for about one-sixth of the national gold output (453 tons).

While making major breakthroughs in prospecting, scientific and technological innovation capabilities in geological prospecting have also been significantly improved.

One is to deepen the understanding of mineralization theory. Carried out research on prospecting and metallogenic model of deep large-super-large gold deposits in the northwestern Jiaodong gold deposit concentration area in Shandong Province, created the "hot-long-extension" metallogenic theory and stepped metallogenic model of Jiaodong-type gold deposits, and obtained national science and technology Progress second prize;

The second is to enrich the gold prospecting prediction theory, and for the first time to create the Jiaodong gold deposit based on the "trinity" prospecting prediction geological model based on the "metallogenic geological body, metallogenic structure and metallogenic structural surface, and mineralization characteristic signs". Greatly enriched and developed the theoretical system of gold prospecting and exploration in China.

The third is to innovate the gold prospecting method, systematically summarize the lateral overburden law of vein-like ore bodies, and significantly improve the effect of deep prospecting.

Fourth, major and substantial breakthroughs have been made in gold exploration technology. The first deep drill for rock gold exploration in China with a hole depth of 4006.17m has created a precedent for deep exploration of metal minerals in my country.

Fifth, significant achievements have been made in the construction of scientific research platforms and talent teams, and the establishment of the "Key Laboratory of Gold Mineralization Process and Resource Utilization of the Ministry of Land and Resources", "Key Laboratory of Metallic Mineral Mineralization and Resource Utilization of Shandong Province", and post-doctoral research workstation , Academician Expert Workstation, etc., 1 person won the Li Siguang Geoscience and Technology Award, 2 persons were approved as the Taishan Scholar Distinguished Expert, and many won the Young Geological Science and Technology Award of the Chinese Geological Society.

In addition, in the deep prospecting breakthroughs in Jiaodong, we have gained successful experience in implementing new mechanisms to achieve prospecting breakthroughs. The major breakthrough in the deep exploration of gold mines in the Jiaodong area is a successful example of the practice of the new geological prospecting mechanism of "public welfare first, commercial follow-up, fund connection, integrated exploration, and rapid breakthrough". Provincial-ministerial cooperation has played an important role in deep prospecting in the Jiaodong area. The central government’s special project is to improve the level of basic geological work and research, and play a leading role. The provincial financial funds have set up a "special project for integrated exploration", which further reduces the risk of exploration and effectively Stimulating investment in enterprises, while increasing technical research and expert guidance, is the joint action of the linkage of ministries and provinces and the combination of industry, education and research to promote the achievement of major results.

The major breakthroughs made in the deep exploration of gold deposits in the Jiaodong area demonstrate the huge resource potential of deep prospecting. The national mineral resource potential evaluation predicts 3,972 tons of shallow gold resources of 2000 meters in the Jiaodong area. The results of the prospecting prediction project in the integrated exploration area show that the Zhaoping fault zone of the three major metallogenic fault zones in Jiaodong (Sanshandao fault zone, Jiaojia fault zone and Zhaoping fault zone) only predicts gold resources in the Damoqujia-Shangzhuang section The amount is 2,160 tons, and the drilling has been verified in the deep part of Guojiabu and Dayingezhuang, showing the great potential of deep prospecting.

2. The next step

Since the implementation of the prospecting breakthrough strategy, the Jiaodong area has continuously added 6 gold mines with more than 100 tons of resource reserves, which has strengthened the confidence of "advancing into the deep earth". In the next step, we will follow the spirit of General Secretary Xi Jinping’s speech at the National Science and Technology Innovation Conference as a guide in advancing the exploration breakthrough strategy, thoroughly implement the Ministry’s "three deep and one soil" technological innovation strategy, and promote the deep prospecting experience in Jiaodong. Speed ​​up the deep exploration of resources.

The first is to carry out deep prospecting in key mining areas. Relying on the national geological survey special project, organize and carry out deep metallogenic prediction, deep drilling verification and prospecting demonstration in the deep edge of the prospective mining area, guide and pull the mining enterprises in the area to follow-up exploration, and provide large-scale resource bases in the central and eastern regions. Continue resources. In the near future, it is planned to hold an on-site seminar on deep prospecting with the participation of relevant provinces in the central and eastern regions in Yantai to deploy related work.

The second is to strengthen the connection with major scientific and technological projects of deep earth exploration. Closely integrate the major scientific and technological projects of deep earth exploration with the prospecting work in ore concentration areas, and the core technical force of ore concentration areas actively participate in the related research of major scientific and technological projects of deep earth exploration, so that the research results can be quickly transformed into specific practices for guiding deep prospecting. Not only has the research results of deep exploration been obtained, but also the prospecting results of greatly increased resource reserves.

Question from reporter:

[Reporter] Compared with shallow resources, the exploration and development costs of deep mineral resources are higher. May I ask: Is it economically feasible to promote deep resource exploration and development?

[Yu Haifeng, Director of the Geological Prospecting Department of the Ministry of Land and Resources] Since the founding of the People’s Republic of China, most of my country’s mineral development has been near the surface, probably within 500 meters. With the passage of time, more and more mines have entered the late service stage, and the reserve resources have been greatly reduced, coupled with the disturbance of the ecological environment caused by near-surface development, which has seriously affected the sustainable and healthy development of the mining economy.

Last year, General Secretary Xi Jinping emphasized at the National Conference on Science and Technology Innovation that “the advancement of the deep earth is a strategic scientific and technological problem that we must solve” and cited an example of deep resource exploration and development: “Theoretically speaking, the available mineralization space inside the earth Distributed from the surface to the underground 10,000 meters, the current world advanced level of exploration and mining depth has reached 2500 meters to 4000 meters, while most of our country is less than 500 meters." Experts predict that if the exploration and development depth reaches 2,000 meters, the supply of solid mineral resources in my country can be doubled on the existing basis. With the steady recovery of my country's economy and the start of the Belt and Road strategic infrastructure construction, the price of bulk minerals has rebounded recently, and the benefits of deep resource exploration will surely be further improved.

At present, many countries such as South Africa are promoting the development of deep minerals and are seeking resources from the depths of the earth. The mining depth of some gold mines has exceeded 4 kilometers, indicating that it is completely economically feasible. At the same time, the development of deep resources has less disturbance to the ecological environment, which meets the requirements of ecological civilization construction. Like this time, major breakthroughs have been made in the deep prospecting of gold mines in the Jiaodong area. Although the government’s effective guidance is key, it is mainly based on the “deep potential” initiative of enterprises.

In short, the rich resources in the deep exist objectively, and the development of deep minerals is feasible. Vigorously carry out deep mineral development to achieve a win-win situation of protecting the ecological environment and ensuring the supply of resources. In the future, we will further promote the deep mineral exploration and development experience and promote the deep expansion of mineral development.

[CCTV Financial Reporter] We know that the current mineral product market is still sluggish, and domestic geological exploration investment has been continuously declining in recent years. At the same time, the construction of ecological civilization has higher and higher requirements for geological exploration, and the geological exploration industry is in a severe situation. Then I would like to ask: In this context, is there any countermeasure in the organization and implementation of the prospecting breakthrough strategy?

[Yu Haifeng, Director of the Department of Geological Prospecting, Ministry of Land and Resources] The reasons why the domestic prospecting market is still getting colder are complicated. There are cyclical and structural factors intertwined, so I won’t go into it here. Faced with the current situation, the next step of the prospecting breakthrough strategic action has been adjusted accordingly. The overall idea is to implement the spirit of the 18th National Congress of the Communist Party of China, the 3rd, 4th, 5th, and 6th Plenary Sessions of the 18th National Congress of the Communist Party of China and the National Science and Technology Innovation Conference, and carry out "three adjustments and one march" in accordance with the requirements of supply-side structural reforms.

"Three Adjustments":

The first is to adjust the work layout, advance and retreat, fully exit the nature reserve, and strengthen mineral exploration beyond the ecological red line;

The second is to adjust the target minerals. While continuing to increase the exploration of large-scale scarce minerals such as oil and gas, copper, manganese, tin, and potash, we will focus on strategic emerging minerals such as lithium, graphite, and three rarefied minerals, such as coalbed methane, shale gas, and shale gas. New energy sources such as dry hot rock and geothermal, as well as important non-metallic minerals with high market demand;

The third is to adjust working methods and vigorously promote green surveys in terms of methods and means. The so-called "one march", as mentioned earlier, is to march into the deep part of the earth in accordance with the spirit of General Secretary Xi Jinping's speech to promote deep resource exploration and evaluation.

Taking a foothold at home and improving the ability to guarantee energy resources is always the "ballast stone" for ensuring resource security and actively participating in global resource allocation. Therefore, the prospecting breakthrough strategy must be unswervingly pushed forward.

[Reporter from China News Service] Regarding the deployment of "advance into the deep earth" just mentioned, I would like to ask a question. In September 2016, the Ministry of Land and Resources held the National Land and Resources System Science and Technology Innovation Conference, and proposed the "three deeps and one soil" technology innovation strategy for deep ground exploration, deep sea exploration, deep space earth observation, and land engineering technology. What are the specific measures for advancing the deep exploration technology innovation strategy?

[Gao Ping, Deputy Director of the Department of Science, Technology and International Cooperation, Ministry of Land and Resources] In order to implement General Secretary Jinping’s important instructions for marching into the deep earth, the Ministry of Land and Resources, in conjunction with the Ministry of Science and Technology, the Ministry of Education, the Chinese Academy of Sciences, and the Earthquake Administration, has improved the strategic layout and condensed Mission objectives, implementation of research projects, and jointly promote the implementation of the deep exploration technology innovation strategy.

The strategic layout for deep exploration of technological innovation has basically taken shape. The first is to incorporate deep exploration into the "Thirteenth Five-Year" National Science and Technology Innovation Plan for major science and technology projects in 2030. The forthcoming national "Thirteenth Five-Year Plan for Science and Technology Innovation in the Resource Field" further clarifies the specific goals and key tasks for in-depth exploration. The second is to promulgate and implement the "Thirteenth Five-Year Plan for the Development of Science and Technology Innovation in Land and Resources" and the "Several Opinions of the Ministry of Land and Resources on Accelerating the Advancement of Science and Technology Innovation", further highlighting the development plans and reforms of scientific and technological innovation and the "13th Five-Year" Land and Resources Industry The layout is closely connected.

In-depth exploration of scientific and technological innovation goals has basically formed a consensus. In order to actively promote the establishment and demonstration of major scientific and technological projects for deep earth exploration research, Minister Jiang Daming of the Ministry of Land and Resources personally took the lead and established a deep exploration research coordination mechanism with the Ministry of Education, the Chinese Academy of Sciences, and the Earthquake Administration, and established a chief expert group and an expert advisory committee. Under the leadership of the coordination mechanism, more than 300 experts in various fields from 53 units across the country have been organized. On the basis of special investigations, after more than 30 discussions, consultations and demonstrations of different scales, the "Major Deep Earth Exploration "Science and Technology Project Proposals", established the overall goal of "seeing the earth, digging deep into resources, and expanding space", and proposed underground space detection and safe use, deep aquifer structure detection, deep mineral resource detection and exploitation, deep oil and gas exploration and exploitation, geothermal There are 8 major tasks in resource exploration and geothermal energy utilization, deep underground observation and crustal activity monitoring, deep exploration frontier technology and equipment, deep exploration and deep process. The expert advisory committee headed by Academician Sun Shu and Academician Li Tingdong unanimously approved the proposal and proposed that it should be implemented as soon as possible. So far, the scientific and technological community has basically reached a consensus on launching and implementing major scientific and technological projects for deep earth exploration.

The task of deep exploration of innovation research has begun. In the national key research and development plan, the key special project of "deep ground resource exploration and mining" was launched, which will build a new mining space of 1500 meters, enter a new exploration depth of 2000-3000 meters, open up a "new continent" for prospecting in coverage areas, and expand oil and gas 10,000 meters deep. New areas, support the breakthrough strategic action of prospecting. At present, the first batch of 11 projects has been launched, and the second batch of projects is in the process of project review.

In order to further strengthen the top-level design and deployment of the “three deeps and one soil” science and technology innovation strategy, the Ministry of Land and Resources and the Ministry of Science and Technology signed the “Science-Finance Cooperation Mechanism Cooperation Agreement”. Under this framework, we are working together with the Ministry of Science and Technology to study and explore Establish a coordinated promotion mechanism for deep exploration technology innovation and the national geological survey project. For example, open the geological survey project deployment and the latest geological survey results data to the scientific research project team, promote innovative research and development areas, pilot demonstration areas, joint research, discussion, and coordinated deployment, so that limited resources can be fully shared and shared, and research and development results can be verified and perfected in time to achieve scientific research The results are directly transformed to accelerate the national geological survey project to quickly realize a major breakthrough in deep resource exploration.

[National Land Daily reporter] I would like to ask how much potential is there for gold resources in Jiaodong area? Can you introduce the future prospecting direction?

[Li Hu, Director of the Department of Land and Resources of Shandong Province] 1. Regarding the issue of the potential of gold resources in the Jiaodong area. We believe that the prediction of the potential of mineral resources is a complex systematic project. As technology advances and geological understanding continues to deepen, the prediction results will continue to change.

The older generation of geologists have made many predictions on the potential of gold resources in the Jiaodong area. Before the liberation and the early days of the founding of the People's Republic of China, only more than 20 tons of gold were discovered in the Jiaodong area. At the end of the 1960s, due to the discovery of the Jiaojia-style gold mine, a series of major breakthroughs were made in the exploration of gold deposits in the Jiaodong area. By 1980, more than 300 tons of gold deposits had been discovered. At the end of the last century, geologists predicted the potential of gold deposits of 1,000 tons. With the continuous improvement of prospecting theory and technical methods, in 2005, it is predicted that the gold deposit potential is 3000 tons. After the completion of the province's important mineral resource potential prediction evaluation in 2012, it is predicted that the potential of shallow gold mines in the Jiaodong area is about 4,000 tons. Since the strategic action of ore prospecting breakthroughs, a series of major breakthroughs have been made in deep ore prospecting in Jiaodong.
