The Sishen lowergrade project phase 2 is currently in exploration stage. The project aims at producing an additional of iron ore for 20 years with the use of advanced beneficiation technology from the lower grade Sishen resources previously classified as waste.
Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.

Jaguar Mining Reports Q2 2018 Production, 17% Lower Cash Costs, Higher Grades and Record Results at Pilar News provided by Jaguar Mining Inc.
Grade is king. It's a mining adage that's never been more true than it is of today's iron ore market in China. Where the difference in price between a 58 per cent ore product and a 62 per cent product might have been 10 to 15 per cent two years ago, today the gap is as wide as 40 per cent.

While the grade of the uranium ore is lower than many mines or potential mines which have the benefit of open cut operation, the fact that copper is a coproduct with uranium from that same ore (at % Cu in the reserves) means that such grades are viable.
This group of activities is designed for the elementary grades 35 and will help students learn about the properties of minerals mined in Nevada using basic scientific inquiry methods; the locations in Nevada where useful minerals are found; and the uses of minerals in our everyday lives.
