Obtain tungsten deposits in new areas Shixing progress

"Jiangxi Shixing whole region south of tungsten, tin, rare, rare earth mineral investigation and evaluation" was issued by the China Geological Survey Bureau, Nanjing Geological Survey geological and mineral survey undertaken evaluation projects, project work for the 2014-2016 period. Objectives and tasks of tungsten, tin, rare, rare earth minerals as the main ore to tin tungsten skarn, greisen and granite tungsten, tin, rare, rare earth ore is the main type in a shixing Chengjiang Liu Shan Luo dam conduct a regional survey and assessment work.

The project is in the "pit Nanshan Shixing a good source of tungsten tin polymetallic ore evaluation" based on the results in 2014 were in the Nanshan district of Shixing pit mine, good source of mine to carry out exploration work demonstration.

Nanshan pit area n No. belt implementation ZK927, footage 499.73m, of which more than 450m thick skarn. Skarn complex components, mainly diopside, actinolite, garnet, wollastonite, scheelite, chalcopyrite, sphalerite, pyrite, galena, molybdenite, magnetic pyrite mineralization and other development. At 192 ~ 225m to actinolite skarn-based, scheelite mineralization, brass and lead-zinc mineralization of the most intense and uniform mineralization (Figure 1). Head estimated by comparing the strongest parts of the scheelite mineralization grade of more than 2% (samples have been sent to the laboratory test analysis). The ore body is not only the n-4 orebody 7 line corresponds with 11 lines containing tungsten metal ore actinolite skarn also corresponds. In addition, the hole also see a number of copper-containing quartz veins and Bismuthinite, molybdenite ore. Tungsten tin polymetallic ore found the Nanshan, one of main ore pit No. n -4 control over the length of the orebody reach 400m forecast of up to 200 000 tungsten resources like on.

Good source region in 2014 to implement ZK304 (Figure 2), footage of 299.33m, the main ore-bearing rocks containing rubidium tungsten polymetallic deposits greisen containing rubidium albite muscovite granite and quartz vein (sample has been sent to the laboratory test analysis) . The hole and the early implementation of the project trenching, drilling, pitting and other works of the 1st ore joint control of the spread of the range above lkm2 confirmed good source of mine has a good vision of rubidium tungsten ore.

In practice prospecting for tungsten tin region, rare, rare earth minerals important key geological problems geological background, metallogenic regularity and prospecting signs a preliminary study, presented in the area looking for tin and tungsten polymetallic ore stratabound skarn tungsten tin polymetallic deposits related to the Upper Devonian-controlled, double-Yanshanian granite "body body" type of granite type tungsten molybdenum metal ore and Yanshanian granite "scores different evolution prospecting ideas "type granite rubidium tungsten, niobium, tantalum polymetallic ores.

Through implementation of the project to achieve a significant progress tungsten and tin ore, enrich and improve the tungsten tin, rare polymetallic mineralization theory, for the eastern Nanling metallogenic belt tungsten, tin, rare metal ore prospecting offer more experience.
