The method of underhand stoping in which the ore is drawn to the level above (Position B in the figure below), is called Cornish stoping. It finds application only when it is necessary to mine a lens of good ore below a level and it is not practicable or financially possible to do the necessary development to come up from underneath. Its disadvantages are the excessive cost of raising both ore and water. Underhand stoping where the ore is drawn from the bottom (Position A in the figure below), has more merit than is usually accorded it, especially in the Western States. On the Rand it has been used almost exclusively - 911 Metallurgist.
