Hunan New ShaoTan Tungsten Ore
In November 13, 2014, Xinshao County, Hunan Province, compiled by the 407 team of Hunan Provincial Geological Prospecting Bureau, successfully filed on the Provincial Bureau of land and resources.
The report shows that the size of the tungsten ore mine in Xinshao County, Hunan Province is a large-scale tungsten mine, proven tungsten resources reserves of 70,400 tons, associated gold, silver, antimony and other metal elements, is expected to mine service life of about 17 years, the total total economic value of about 8 billion yuan. News once broadcast, it led to a warm reaction to the capital market, the listed company's market value increased significantly, because it is the first record of nonferrous metal mineral exploration in Hunan province since 2000, and the reserves are huge. In China, the shortage of tungsten resources is becoming more and more urgent, and the good news is encouraging.
Tan Xian tungsten ore is located in the Cao Jia village, Xin Shao county, an area of 10.29 square kilometers, located in the Longshan mountain metallogenic belt, tectonic, magmatic activity is strong, excellent mineralization conditions. Of course, behind the dazzling achievement is full of geological prospecting people's hardships. According to 407 team members described in 2010 when the exploration work began, they found Tan Xi tungsten ore area geological situation is complex, fault fracture zone development, the surface is not obvious, the depth of the exploration line is very wide, the thickness is generally larger than 100m, the distribution range is wide, the area is large and the depth is large. Early drilling is used to expose the construction period, the cost is high and the effect is poor. Later 407 brigade summed up the failure experience and sort out the mineralization of the Tan Xi mine, decided to use geophysical methods to detect. The result is remarkable. It is not only fast, effective, but also saves a lot of costs.
For four years, the project team completed the field work from detailed investigation to exploration, completed a total of 2.15 square kilometers of 1: 2000 geological survey, 34 for construction drilling, 13358.05 meters for drilling footage, 4 for aquatic test and 4 for mineral processing. It is determined that the type of deposit is stratabound skarn type tungsten deposit, and 12 mineralization layers are numbered, and the amount of ore body is estimated, a total of 57 laying ore body, ore body thickness of 0.64 meters to 17.56 meters, the average grade of 0.367%, submitted to the amount of 19.16 million tons of tungsten ore, tungsten resources 70,400 tons.
Relative to the gold, Tan Xi tungsten ore seems to have more comprehensive mining value, in 2013, Hunan Province, 304 Geological Survey team in the mine Li Ping village found a new generation of tungsten antimony ore belt. In the future, the development potential of Tan Xi tungsten mine is abysmal.
