    stoping, the Janelid method (analogous to an inclined cave) and block caving were all considered as mining methods. Sublevel open stoping was introduced in a trial mining block but, after failure of the method due to premature caving ofthe sill, the mine reverted to mechanized block caving in 1989, a method that is still being used. 5.
