Weilasituo lithium-tin mine unlikely to go into operation in 2020
----Interview with Wang Kexiang

General Manager
Inner Mongolia Weilasituo Mining Co., Ltd.
Founded in 2006 and put into commercial production in 2008, Inner Mongolia Weilasituo Mining Co., Ltd. mainly produces copper, zinc, silver and tungsten. Mining resource began to decline from 2014, so it was hard for the company to reach a new high in terms of output and production volume. Against this background, Weilasituo Mining carried out exploration and discovered a large-scaled lithium-tin polymetallic deposit containing massive lithium and tin ores. The proved reserve and exploitable reserve of tin ore enable the deposit to be one of large-scaled mines of recent years. The discovery of the deposit was one of "2018 top ten geological prospecting achievements" of Geological Society of China. With a great development potential, the deposit has profound influences on tin ore supply in Chinese market.
Asian Metal: Firstly, thank you for accepting our interview. Please give us a general introduction of your company.
Mr. Wang: Located in Baiyinchagan Sumu, Hexigten Banner, Chifeng, Inner Mongolia Weilasituo Mining Co., Ltd. was founded in November 2006 with a registered capital of RMB120 million (USD16.98 million) and 51% interests held by the state. The company started construction in 2007 and went into commercial production in 2008. With a daily beneficiation capacity of 1,000 tons, we can handle 330,000 tons of ore per annum at present. The company focuses on production of copper, zinc, silver and tungsten concentrated mineral products. We halted production of existing zinc-copper polymetallic mine in 2020 due to depleted resources and only run the dressing plant now, which can be in production till this October with raw ore stocks. We discovered a large-scaled lithium-tin deposit within our mining area later by exploring and developing and finished project assessment. Now we are still waiting for approvals from relevant authorities.


Asian Metal: Please tell us something about reserves and ore body of Weilasituo lithium-tin mine.
Mr. Wang: The lithium-tin polymetallic mine in Weilasituo mining area, Hexigten Banner, Inner Mongolia Autonomous Region is a large-scaled lithium-tin polymetallic deposit that was discovered and explored during 2013 and 2017. The total ore reserves are 34.75 million tons, including 6.8 million tons of tin ore and 27.8 million tons of lithium ore, and the total metal reserves include 58,000 tons of tin, 357,000 tons of lithium oxide, 50,000 tons of zinc and 9,000 tons of tungsten trioxide. In particular, tin ore and lithium ore are of massive scale. The average grade of the deposit is 1.3% lithium oxide, 0.85% tin, 1% zinc, 0.2% tungsten trioxide. The exploration report passed the review of Mineral Reserves Accreditation Center of Inner Mongolia Autonomous Region and filing procedure was put to an end. We are applying for designation of mining area at present. The mine of large scale, high grade, many valuable elements and simple beneficiation process is a rare high-quality deposit.
Asian Metal: What are your expectations for the output of tin concentrate and other mineral resources after commercial production of this mine?
Mr. Wang: Based on comprehensive analysis on mineral reserves of the mine, we plan to construct a green environment-friendly mine with an annual ore beneficiation capacity of 2.05 million tons, including 400,000 tons of tin ore and 1.65 million tons of lithium ore. The products will be tin concentrate, lithium concentrate, tungsten concentrate, zinc concentrate and others. After reaching the designed annual production capacity, we will produce about 7,000 tons of tin concentrate 60%min, about 550,000 tons of lithium concentrate 3.12%min, about 4,000 tons of zinc concentrate 50%min and about 560t of tungsten concentrate 65%min on average per annum.
