Xikeng Tungsten-Tin Mine Holds 6,498.32 Tons of WO3

According to the announcement of the Department of Natural Resources of Jiangxi Province, as of September 30, 2020, the estimated value of the transfer of mining right from Xikeng tungsten-tin mine in Jiangxi Province is 30.368 million yuan with 6,498.32 tons of WO₃.

The estimated value of the profit from the transfer of retained recoverable reserves is 23,844,100 Yuan. From September 30, 2006 to December 31, 2019, the estimated value of the proceeds from the transfer of consumed recoverable reserves without paid disposal is 6,524,700 yuan.

Xikeng tungsten-tin mine is located in Xiaguan Village, Guantian County, Chongyi County. In 1959, the tungsten mine survey and exploration team of Jiangxi Geological Bureau conducted geological exploration in the mining area and determined that the mining area has certain mineral resources reserves.

The genetic type of the deposit is divided into high-temperature hydrothermal filling quartz vein type tungsten-tin deposits. The industrial type of the deposit is divided into wolframite-sulfide-quartz vein type deposits. According to the ore body shape, it is divided into quartz vein type tungsten-tin deposits.

The mining right evaluation area is 3.8457 square kilometers, the production scale is 32,000 tons/year. The evaluation period is 30 years, and the mine service period is 49.95 years.

As of the assessment base date, the retained (122b+333) ore volume is 721,93 tons, WO3 volume is 6,498.32 tons, with an average grade of 0.90%, and Sn volume is 6,581.14 tons with an average grade of 0.91%. Among them, the amount of 122b ore is 181,483 tons, the amount of WO₃ is 2,482.98 tons, the average grade is 1.368%, the amount of Sn is 985.04 tons, the average grade is 0.543%.

The amount of 333 ore is 540,447 tons, the amount of WO₃ is 4015.34 tons, and the average grade is 0.743%. The amount of Sn is 5596.10 tons, with an average grade of 1.035%. There are 721,600 tons of associated (333) ore, 491 tons of Cu with an average grade of 0.068%, and 3.09 tons of Ag with an average grade of 4.28 (10-6).

From September 30, 2006 to December 31, 2019, the (122b) resources in Xikeng tungsten-tin mine used for unpaid disposal are 126,700 tons of ore, 1911.68 tons of WO₃, and 720.6 tons of Sn. The total resources of these two items are 848,800 tons of ore, 8410.00 tons of WO₃, and 7,301.74 tons of Sn. The amount of associated (333) ore is 721,600 tons, the amount of Cu is 491 tons, and the amount of Ag is 3.09 tons.
