Songjiagou Molybdenum Mine Utilization Plan Passed Examination

The "Songjiagou Molybdenum Mine Resources Development and Utilization Plan in Luonan County, Shaanxi Province" has recently passed the review of experts from the Oil and Gas Resource Strategy Research Center of the Ministry of Natural Resources. The mine located at the core of the Huanglongpu molybdenum ore field in Luonan County is the second-largest molybdenum mine in Shaanxi Province.

It is reported that Songjiagou Molybdenum Mine has reviewed and filed molybdenum ore resources of 302,497,700 tons, and metal content of 305090.72 tons, with a grade of 0.101%. Among them, the proven intrinsic economic resources (331) are 66,051,000 tons of ore, 63,094.91 tons of metals, and the grade is 0.096%. The controlled intrinsic economic resources (332) are 141,743,400 tons of ore, and the metals are 144,842.59 tons, and the grade is 0.102. %, the inferred inherent economic resources (333) ore amount is 94,703,300 tons, the metal amount is 97153.22 tons with a grade of 0.103%.

Also, the amount of associated lead ore is 302,497,700 tons, the amount of metal is 789,500 tons, and the grade is 0.261%. The amount of associated sulfur ore is 302,497,700 tons, the amount of element is 6.0112 million tons, and the grade is 2.76%. The amount of associated silver ore is 302.4978 million tons, and the amount of metal is 626.17 tons with a grade of 2.07%.

The Songjiagou Molybdenum Mineral Resources Development and Utilization Plan passed the review and the resource reserves are reasonably utilized. The review results pointed out that the "Plan" re-estimated the resource reserves, and the error is smaller compared with the survey report, which can be used as a design basis. The "Plan" is designed to utilize 273.5 million tons of molybdenum ore resources, 283,271 tons of metal, and a grade of 0.104%.

The "Plan" design is based on factors such as mineral reserves, exploration level, ore body storage conditions, mining technology, owner investment and mining area planning, etc. The recommended mine production scale is 6.6 million tons/year, the service life is 67 years which is reasonable. According to the review, the mining method, development system, and mining method are reasonable.

Carrying out beneficiation test work, determined molybdenum-lead mixed flotation, tailings sulfur separation, mixed flotation concentrate molybdenum, lead separation flotation, flotation tailings weak magnetic iron separation process and molybdenum concentrate, lead concentrate, sulfur concentrate, iron ore product plans and design indicators are reasonable, and feasible.

The expert review suggested that the carbonate-type molybdenum deposits in the Huanglongpu area have high associated heavy rare earths and have potential use-value. It is recommended that further research on the occurrence and comprehensive utilization potential of heavy rare earths can be considered in the future production process.

Experts reviewed that the plan met the requirements of the former Ministry of Land and Resources for the "three rates" indicator requirements for the rational development and utilization of the Songjiagou molybdenum mine resources. This plan shall not be used as the basis for the evaluation of the income from the transfer of mining rights.
