GSI 2016 Paper III Q7 (b) Calculate ore reserve of a 5 m thick ore blocked out between two levels, separated by 30 m, and ready for immediate extraction. The length of the ore block is 40 m and the bulk density of the ore is 2-73 gm/cc. Assuming 0-63% average grade of copper, how much copper metal can be obtained from the block with 90% recovery ?
