Assume the open pit mining the costs are $2.75/ton of ore (OP) and a stripping cost of $1.85/ton of waste (SC). SR = (UG - OP)/SC SR = (12.00 –2.75)/1.85 = 5.0 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.0 it is most profitable to mine the deposit by open pit. When the stripping ratio exceeds 5.0 it will be more profitable to mine the deposit using the underground
