MINING METHOD OF THE WEEK - SUBLEVEL LONGHOLE!!

This bulk underground mining method involves mining large amounts of material from a single stope – similar to cut and fill, this method starts at the bottom of a level and moves upward. Ore is removed from the bottom, and then more ore is blasted from a higher level that falls to the same level to be removed, with the process repeating up the ore body. The supporting walls need to be very strong in order to support the large underground openings that will be created by this process - New Pacific Metals Corp.
