Eventually there comes a point where the revenue from the exposed ore is less than the costs involved in its recovery. Mining then ceases. The ratio of the amount of waste rock stripped to ore removed is called the overall stripping ratio. The break-even stripping ratio is a function of ore value and the costs involved. Ore reserves
