(PDF) Stripping Ratios, Pit Limits & Cutoff Grade

For open pit mining the costs are $0.40/ton ore and a stripping cost of $0.50/ton of waste. SR = (3.00 -0.40)/0.50 = 5.2 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.2 it is most economical to mine the deposit by open pit. With mining of bench 8, another 5,000 ft 2 of ore (A 6 ) is removed.
