• Ore grade/method cost • Rock quality • Waste Disposal The ore body must be narrow and steeply dipping as the method relies on gravity to draw ore Cut and fill is a very expensive mining method due in large part to the high costs of backfill This cost can be justified if the ore body is of a particularly high grade
