800 meters underground discovery of tungsten and molybdenum Lujiang

Both tungsten and molybdenum mineral resources are very rich in China, the reserves in the world, is also at the forefront, but both before and mineral resources within the scope of Hefei has not been found. Recently, good news from Anhui Geology and Mineral Bureau 327 teams came Luzong basin in the northern region (Lujiang County) discovered a new type of mineralization - tungsten ore, molybdenum ore, these two mineralization types Hefei range within the region and belong to the first time.

800 meters underground discovery of tungsten and molybdenum

December 2014, cold. Lujiang County, located along the harbor areas of Gu Shan copper polymetallic ore pre-inspection of the project site, Anhui Geology and Mineral Bureau 327 team is trying to rig construction, geological team wrapped in a thick coat of arms stick around the rig. Drill cores extracted with upward geological team's heart began hanging up. It has been four months since the start of drilling rigs operating in the 800 meters underground.

"Come and see, if there is something!" From the ground up to a length of 870 Rice on the core, the core of fractures in geological team saw a gray shiny light. Geological team are overjoyed, everyone have gathered around, geological team saw the leaden shiny molybdenite, and with the test equipment into the core invisible scheelite.

Tungsten and molybdenum discoveries like to geological team have injected a shot in the arm, in the cold, geological team to continue to squat core side of the box, carefully observed and recorded the extracted core samples. Outdoor temperature is cold, but the geological team's heart is warm.

Geological team braved the bitter cold on a day like this stick in the next drill, observing from greater depths to extract cores up every day. Recently, the rig drilling the final 1410 meters final hole in the ground to determine the area underground deposits of tungsten ore and molybdenum. In addition to discovering tungsten ore, molybdenum ore, Anhui Geology and Mineral Bureau 327 team is still drilling depth for the first time we found a "granite", which in turn is an important prospecting clues.

According to Anhui Geology and Mineral Bureau 327 team technical staff, he said in Hefei had been not been found tungsten ore and molybdenum, tungsten and molybdenum mine geological team discovered the 327 Luzong basin in the north (Lujiang County), It belongs to the first time in the history of Hefei area.

Good high grade mining prospects

Lujiang County, Port area has a good background in the geological mineralization.

According to Anhui Geology and Mineral Bureau 327 technical staff, said the team from the beginning of the 1960s, 327 geological team already carried out in the region for geological prospecting discovered mineralization is widespread in the region, rich in types.

August 2014, prospecting for early clues, combined with a comprehensive analysis of geological and geophysical and geochemical results of the 327 Geological Team, it was decided that the project team along the harbor area in East Gu Shan "Daikin concave" construction drilling verification. Perhaps "ancient sometime grind", because the area is more complex structure, rig construction encountered great difficulties. To drill inclination to specifications, sometimes drilling technicians around the clock for several days in the field study, op.

With the progress of the construction, although extraction up has been found to have a strong core of "alteration" phenomenon, also we got some mineralization clues, but we have not reached the desired objectives prospecting. Sometimes it does not seem to extract the core mineralization clues, some even younger geological team disappointed, laughing, "underground here is really clean."

But this time the team repeated observation and discussion of research, decided to continue to explore for deep cores extracted. Eventually, when the borehole construction to 870 meters underground fissures found leaden core sparkling molybdenite, and with the test equipment into the core invisible scheelite.

According to reports, the Drilling is ZK2 (Drilling of borehole number), extracted by the drilling core samples and found that depending on the thickness of 32.61 meters tungsten ore body containing an average grade of 0.19% WO3; molybdenum ore body depending on thickness 48.09 meters, containing an average grade of 0.289% Mo. Technical staff, said, according to the data, the discovery of tungsten and molybdenum mine higher grade, with good prospects for exploitation.
