The exploration area is located in Shujiadian, Zhongming Town, Tongling County, Anhui Province, and the administrative division is under the jurisdiction of Zhongming Town, Tongling County, Tongling City. The survey area is 7.58 square kilometers. The exploration area is 5 kilometers north of Tongling-Nanjing Railway and 4 kilometers north of Jiang Yan Expressway. Tongling City and Tongling Changhang Port can reach other places through provincial highway 32 1, and the land and water transportation in the area is very convenient. This area belongs to subtropical humid monsoon climate. This area mainly produces grain, and the crop economy is not very developed. Farmers' income is mainly radiated by urban economy, and the economy is relatively developed.
From 2007 to 20 13, 1 1, East China Institute of Metallurgical Geology carried out exploration work, and the exploration mineral was copper, with a census work and exploration fund of 48.63 million yuan.
(2) Brief introduction of achievements
The mineralization of the deposit is strictly controlled by Shujiadian pyroxene diorite, and the diagenesis and mineralization are related to Shujiadian anticline and its derived NE-trending faults. The ore types are mainly copper-bearing disseminated, veinlet and veinlet pyroxene diorite, and the deposit is porphyry. The future mining mode of copper resources in this deposit is early open-pit mining and later underground mining. The main section of open-pit mining is 6 ~ 16 line -400 meters above.
* * * Found 699,400 tons of metallic copper with an average grade of 0.32%, including 350,400 tons of industrial grade metallic copper with an average grade of 0.47% and 349,000 tons of low-grade metallic copper with an average grade of 0.24%. Associated (333) sulfur is 6,482,200 tons, with an average grade of 2.93%, and metallic gallium is 57,95910 kg, with an average grade of 0.0026%. The amount of associated gold and metal is 13264 kg, and the average grade is 0.12×10-6; Associated silver metal is 292760kg, with an average grade of1.76×10-6; The average grade of molybdenum is 0.0 103%, and the metal content is 2279 kg.
(3) the brief process of achievement
The project was established in Anhui Geological Exploration Fund in 2006 and started in 2007. The first field inspection was conducted from June 5 to February 5, 2008, and continued in 2009. The second field inspection was carried out in October11August, and the work continued. 201June 3 19 third field acceptance, and approved to continue again. 201311kloc-0/October 10 for the fourth field acceptance in the second half of the year. From 2007 to 20 13, 1 1, East China Metallurgical Geological Exploration Institute carried out exploration work, and * * * completed the drilling workload of 3 1394m. The project passed the first phase evaluation meeting of "Anhui Geological Prospecting Breakthrough Strategic Action" organized by Anhui Public Welfare Geological Survey Center.
