77,000 Tons of WO3 Estimated in Youmapo W-Mo Deposit

77,000 tons of WO3 compounds are predicted in Youmapo W-Mo deposit. The Natural Resources Department of Guangxi Zhuang Autonomous Region intends to transfer the mining right of the Youmapo W-Mo deposit in Bobai County. On June 30, 2020, the estimated value of the mining right transfer proceeds is RMB 170,514,100.

Among them, the estimated value of the transfer income corresponding to the estimated utilization of 17.066 million tons of resource reserves is 142.5168 million yuan, and the estimated value of the transfer income of the associated minerals molybdenum, gallium, germanium, and bismuth is not designed to use is 27.9973 million yuan.

The Youmapo W-Mo deposit is located in the southwest section of the Bobai-Cenxi fault zone, and the direction of the structure line is NE-SW. The approved mining area covers an area of 1.168 square kilometers; the mining area is delineated by 10 turning points, and the mining elevation ranges from 262 meters to -560 meters. A total of 77 tungsten, molybdenum, and sulfur ore bodies have been delineated within the scope of prospecting rights, including 29 tungsten ore bodies (20 industrial ore bodies), 41 molybdenum ore bodies (25 industrial ore bodies), and industrial pyrite ore bodies of 7.

According to the evaluation report on the profit from the transfer of the mining right of the Youmapo W-Mo deposit in Bobai County, the mine’s estimated utilization of resource reserves is 17.066 million tons, the amount of WO3 compounds is 77004.00 tons, and the average grade is 0.451%; the total (associated) S ore volume is 4.0758 million tons. , S metal content is 793,639.00 tons, average grade 19.472%; Cu metal content is 15,359.94 tons, average grade 0.090%, Ag metal content is 107.52 tons, average grade is 6.300 g/ton.

The design loss for the evaluation is 1,683,100 tons, (331) and (332) are all involved in the evaluation calculation, the (333) credibility coefficient is 0.65, and the mining recovery rate is 92%.

The estimated utilization of recoverable reserves is 11.9641 million tons, WO3 compound content is 57175.89 tons, average grade 0.478%. Total (associated) S ore volume is 2,848,100 tons, S metal content is 558,237.76 tons, average grade 19.600%. Cu metal content is 10,767.65 tons, the average grade is 0.090%, the amount of Ag metal is 75.37 tons, and the average grade is 6.300 g/ton.

The mine's production scale is 60,000 tons/year, the ore dilution rate is 9%, the theoretical service life of the mine is 19.92 years, the infrastructure period is 3.00 years, and the estimated calculation life is 22.92 years.

The product plan is heavy separation of tungsten concentrate (grade 50%), fine tungsten concentrate (grade 20%), sulphur concentrate (grade 45%), copper concentrate (grade 16%), copper concentrate with silver grade 91.22 G/ton.

The recovery rate of the beneficiation in Youmapo W-Mo deposit is that the tungsten concentrate contains 50.00% WO3, the fine tungsten concentrate contains 20.00% WO3, the sulfur concentrate contains 73.00% sulfur, the copper concentrate contains 69.00% copper, and the copper concentrate contains 5.62% silver.
