Popular Answers ( 1) A high grade orebody can support a high stripping ratio. A low grade ore body cannot support a high stripping ratio. The cost is purely driven by the cost of the mining fleet (capital and operating costs) to move the waste ore. Larger scale operations who can maximise the economies of scale can be profitable with low grade and higher strip ratios.
