2016-4-4 The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR).This represents the highest possible units of waste that can be handled. If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining.

4.1.7 CUT-OFF STRIPPING RATIO OR BREAK-EVEN STRIPPING RATIO The stripping ratio at which the cost of mining the ore and waste is equal to the revenue from that ore. The cut-off stripping ratio is the same as the break-even stripping ratio. This is the stripping ratio at which the net value of the last increment of ore is just sufficient to pay for the cost of removing the waste to release the ore.
