Non-profit geological work has promoted the first batch of 47 comprehensive exploration areas in China to make significant progress in prospecting (Figure 5-3). According to preliminary statistics, in 20 1 1 year, the newly-increased resources (above 333) in 47 comprehensive exploration areas are 4.24 billion tons of iron ore, 21270,000 tons of copper, 48.72 million tons of bauxite, 0/77.3 tons of gold, 6.54.7 tons of silver and 2.7 tons of lead and zinc.

Continue to assess the potential of important minerals. Complete the compilation of provincial basic geological maps and the construction of basic databases. National * * * completed 687 actual material drawings of1:250,000 and 730 architectural structure drawings of1:250,000; Complete basic geological mapping and database construction of provincial gravity, magnetic survey, geochemical exploration, remote sensing and natural heavy sand; Complete the maintenance of the provincial-level basic geological database, adding mineral data 1. 1.9 million, adding geological work data records 1.65 million, and a large number of geophysical survey data and vectorization data of geological maps; The compilation of national comprehensive maps and the construction of databases have been steadily advanced.
Complete the resource potential evaluation of coal, uranium, iron, copper, aluminum, lead, zinc, tungsten, antimony, gold, rare earth, potassium and phosphorus 13 minerals. The potential evaluation of copper resources shows that the national 500-meter shallow forecast resources are 65.438+92 million tons, 65.438+0.000-meter shallow forecast resources are 274 million tons, and 2000-meter shallow forecast resources are 306 million tons (Figure 5-4).
Hunan Huayuan-Fenghuang lead-zinc mine has added 3 million tons of resources. More than 500 million tons of iron ore resources have been added to the periphery of Dataigou iron mine area in Benxi, Liaoning Province. Tibet is rich in Tsukagoshi Hirotaka super-large copper and gold deposits, with an estimated copper resource of 5.77 million tons and gold of 260 tons. Xinjiang Awulale iron and copper mine has added 260 million tons of iron ore resources. Morach, Cikl and other iron mines have been newly discovered in Tashkurgan, West Kunlun, with an estimated resource of 800 million tons. Two super-large iron polymetallic mines and four large copper polymetallic mines have been discovered in Qimantage, Qinghai, with iron ore resources of 480 million tons and copper, lead and zinc resources of 4.2 million tons. The proven gold resources of Da Qiao Gold Mine in Gansu Province are 70 tons.
Investigation of sea sand resources. We will continue the comprehensive investigation and evaluation of mineral resources in the coastal zone of South China, the investigation of offshore sand and related resources potential in Liaodong Bay, the investigation of offshore sand and related resources potential in the west coast of Taiwan Strait, and the investigation and evaluation of offshore sand resources potential in Hainan Island. At the same time, a joint survey of marine sand resources in the North Yellow Sea was carried out.
