Cut and fill stoping is a more selective mining method than sublevel caving, which is expected to achieve greater recovery of ore as well as reducing the dilution of ore with unmineralised material. It is a bottomup mining method involving drilling, blasting and mucking out of ore before filling voids. Backfill
