Liangbizhou Tungsten Mine Holds 2,76.09 Tons of Tungsten

According to the announcement of the Department of Natural Resources of Jiangxi Province, as of July 31, 2020, the assessment base date, the assessment value of the income from the transfer of the mining right of the Liangbizhou tungsten mine in Suichuan County was RMB 7,222,800. Including the value of proceeds from the sale of tungsten ore of RMB 6,298,900 and the value of proceeds from the sale of molybdenum (associated ore) of RMB 19,200.

The Liangbizhou Tungsten Mine in Suichuan County is located in the northeast of Suichuan County with an area of 18Km at 80° in the northeast. The mining right assessment area is 1.8556 square kilometers. The validity period is from December 2018 to June 14, 2019. In 1924, the Tungsten Mine was discovered and mined by the Red Army. The mining rights belonged to the Liangbizhou Branch of the Xiaolong Tungsten Mine of Jiangxi Tungsten Group. In September 2002, it was changed to Liangbizhou Tungsten Mine. The mining has been suspended since 2016.

As of July 31, 2019, the retained resources of Liangbizhou Tungsten Mine included 212,694 tons of tungsten ore resources (122b+333), 2,67.09 tons of tungsten metal, with an average grade of 1.26%. The associated molybdenum ore (333) was 213,000 Tons, 35 tons of molybdenum metal, with an average grade of 0.017%.

After September 30, 2006, the resource reserves consumed in the mining license need to be paid for the profit from the transfer of mining rights. The consumed resource ore (122b) was 85,751 tons, tungsten was 852.12 tons, with an average grade of 0.99%.

On the base day of the assessment, the retained resources and reserves of tungsten ore (122B +333) were 298,468 tons, and tungsten was 3528.21 tons, with an average grade of 1.18%. The amount of molybdenum associated ore (333) was 213,000 tons, and the amount of molybdenum metal was 35 tons, with an average grade of 0.017%. The credibility coefficient was 0.65. The amount of tungsten ore used in this evaluation was 257,400 tons, and the amount of tungsten metal was 3001.43 tons, with an average grade of 1.17%.

The comprehensive recovery rate is 90.00%, the design loss is 0, the estimated and utilized recoverable reserves are 231,700 tons, the amount of tungsten metal is 2701.29 tons, the dilution rate is 70.00%, the estimated production scale is 40 thousand tons/year, and the mine service life is 19.31. The evaluation calculation period is 20.31 years (including a one-year reconstruction and expansion period).

Up to now, a total of 37 tungsten veins with industrial value have been identified in the Liangbizhou tungsten mine area, and the main veins are arranged roughly in parallel. The metal minerals in the ore are mainly wolframite, a small amount of scheelite, molybdenite, trace amounts of bismuthite, chalcopyrite, pyrite, sphalerite, and arsenopyrite, etc. The non-metallic minerals mainly include quartz, small amount of fluorite, orthoclase, muscovite, trace calcite, beryl, and pyrophyllite, etc.
