Inner Mongolia Xingye Silver&Tin Mining Co. said that Yinman Mining has been in normal production since its technical transformation and put into production. As of now, the registered tin reserves of Yinman Mining have not changed.
Compared with the upper elevation of 810 meters, the geological characteristics of the No. 17 ore body currently mined have changed significantly. The grade of silver has slightly decreased, but the change has not been significant. As of the end of 2022, Yinman Mining has approximately 8,600 tons of silver resources.
No. 17 ore body is currently the main ore body mined in Yinman III area. This ore body can meet the demand for copper and tin ore of Yinman Phase I dressing plant every year. According to statistics on the mining situation in Area III, the scale of No. 17 ore body is within the range of 690 to 920 meters (approximately 200 meters). The scale of No. 17 ore body at 690 meters depth is under investigation. Based on preliminary exploration and phased research, it is believed that the deep parts of the Yinman mining area have the potential for porphyry copper-tin deposits, and the deep ore prospecting potential of the Yinman mining area is huge.
Calculated based on registered reserves and designed production capacity, Yinman Mining has a service life of more than 30 years and will officially enter production at the end of 2016. As of now, Yinman Mining has not re-evaluated the mining life.
