Squareset stoping is a flexible method; it can be accommodated to very irregular ore bodies, large or small, and permits following and mining offshoots of ore with minimum dilution and loss of ore. Waste can be sorted out and left in the gob. The method can be adapted where sudden changes in dip of the deposit occur and to following ...
