At the end of March, the Science and Technology Department of Qinghai Province organized experts to conduct an acceptance of the provincial key R & D and transformation plan project "Deep Resources Prediction Research on Large-Scale and Large-Scale Gold Deposits in the Northern and Southern Margin of Qaidam of Qinghai Province."** The acceptance and evaluation results show that the project research has achieved results. The submitted prospecting target area has been verified by the project, adding 43.2 tons of new gold resources, creating potential economic value of more than 20 billion yuan. **

据了解，该项目由青海省第一地质勘查院联合中国地质大学（北京）、都兰金辉矿业有限公司、大柴旦矿业有限公司共同承担，2021年以来在青海省柴达木南北缘滩间山、五龙沟金矿取得找矿重大突破。 The result achieved this time is the first time that Qinghai Province has discovered the second metallogenic enrichment space deep in a large gold deposit, indicating that a large super-large gold deposit on the northern and southern margin of Qaidam in Qinghai Province has the potential to form a world-class "Jiaojia-style" gold deposit in Shandong 。

Known as China's "treasure basin", the Qaidam Basin is located in the Haixi Mongolian and Tibetan Autonomous Prefecture of Qinghai Province, with an area of 256,500 square kilometers. It is one of China's important energy and mineral resource-rich areas. Among them, the Tanjianshan gold deposit located on the northern edge of the Qaidam Basin and the Wulonggou gold deposit on the southern edge of the Qaidam Basin are the most representative large and superlarge gold deposits in Qinghai Province, and are also demonstration mines integrating "scientific research-exploration-development" in Qinghai Province.

The multi-stage characteristics of large-scale gold mineralization in the northern and southern margin of the Qaidam Basin and the multi-stage regional structural and magmatic hydrothermal activities have led to insufficient understanding of gold metallogenic laws and ore-controlling factors in the study area. In addition, the low level of deep gold positioning prediction research and single technical means restrict the rapid evaluation and prospecting breakthroughs in deep gold deposits.

The project carried out research on the theory and technical methods of deep gold prospecting in the northern and southern margins of the Qaidam Basin, and proposed the coupling relationship between large-scale gold metallogenic events in the southern and northern margins of the Qaidam and collision orogeny between the original Tethyan Ocean and the Paleo-Tethyan Ocean. and post-collision orogeny, and established the Tanjianshan and Wulonggou gold metallogenic models and three three-dimensional geological models of the main Qaidam gold ore fields; An effective method combination system for deep prospecting in Wulonggou and Tanjianshan has been developed, 1 deep exploration demonstration project has been established, and 12 deep prospecting targets have been submitted.

** The implementation of the project will help improve the province's deep mineral resource exploration capabilities, accelerate the pace of exploration of advantageous resource gold, achieve new breakthroughs in gold resource exploration, give full play to the supporting role of scientific and technological innovation, and provide strong support for the province's deep mineral resource exploration. **

According to the "Chronicles of Mineral Geology of China·Qinghai Volume·Popularized Edition", as of the end of 2017, Qinghai Province had identified 481.66 tons of gold resource reserves and 347.17 tons of retained resources. So far, 346 gold ore producing areas have been discovered in Qinghai Province. The largest gold mine is the Dachang Gold Mine in Qumalai County, Yushu Tibetan Autonomous Prefecture, with gold resources of 108.63 tons.
