(1) General situation the No.134 vein extension exploration area is located at 290 north-west of Kangding County ° The direction is 70 kilometers away, belonging to Tagong Township, Kangding County. From the mining area to s215 provincial road, there are 33 kilometers of simple roads, 108 kilometers from Tagong to Kangding, and 477 kilometers to Cheng, with convenient transportation. The mining area is 4100-4820 meters above sea level, with relatively bad climate, large temperature difference between day and night, and poor working conditions. It is a famous lightning strike area in China, with backward economy and mainly Tibetan nomads
108 geological team of Sichuan Bureau of Geology and mineral exploration and development explored the ore blocks below the mining right. The exploration mineral is spomene, and the degree of work is exploration. The exploration fund is 9.75 million yuan
(2) achievement description
the ore deposits are mainly granite pegmatite type organic mineral deposits, the veins are branched lenticular and vein like, and there are 11 branched small veins distributed in the upper and lower walls of the main vein, of which the main vein is 1003m long, 180-385m deep and 19.5-69.66m thick, with NW tendency and steep dip angle °, The main useful minerals are spomene, beryl and niobium tantalite. The average grade of the deposit is Li < sub > 2 < / sub > o 1.42%, BeO 0.04%, Nb < sub > 2 < / sub > o < sub > 5 < / sub > 0.012%, Ta < sub > 2 < / sub > o < sub > 5 < / sub > 0.005%, respectively. Lithium beryllium is easy to be beneficiated. According to the evaluation of Sichuan Mineral Resources Evaluation Center (CBR [2011] No. 216): the original mining right reserves: (111b + 333) ore amount is 5.261 million tons, Li < sub > 2 < / sub > O resources amount is 77207 tons, associated BeO resources amount is 2397 tons, Nb < sub > 2 < / sub > o < sub > 5 < / sub > 723 tons, Ta < sub > 2 < / sub > o < sub > 5 < / sub > 353 tons; The newly added resources in the exploration right (extended exploration section): (111b + 122b + 333) ore amount is 23.734 million tons, Li < sub > 2 < / sub > O resources amount is 335066 tons, associated BeO resources amount is 10376 tons, Nb < sub > 2 < / sub > o < sub > 5 < / sub > 2803 tons, Ta < sub > 2 < / sub > o < sub > 5 < / sub > 1151 tons. Lithium resources have reached the scale of large-scale deposits, and associated minerals have reached the scale of medium-sized or above
(3) the brief process of achievement the exploration work lasted for five months, and the formal exploration results reviewed by Sichuan mineral resources and reserves evaluation center have been submitted to the client (all exploration results are kept by the company)
